ABSTRACT

Objective: To examine the value of intravascular ultrasound (IVUS) for excimer laser ablation (ELA) combined with drug-coated balloon (DCB) in treating lower limb arteriosclerotic obliterans (ASO). Methods: As a prospective case series study, patients who underwent ELA combined with DCB for lower limb ASO with the guidance of IVUS from September 2021 to March 2022 at Department of Vascular Surgery, Zhongshan Hospital, Fudan University were enrolled prospectively. Lesion characteristics, procedure-related outcomes and complications were collected. The therapy outcomes were compared with baseline data by paired t test. Results: There were 8 males and 2 females, aged (72.0±5.9) years (range: 61 to 81 years). Of all the 11 lesions, there were 8 lesions in superficial femoral artery and 3 in popliteal artery. The lesion length was (7.0±2.4) cm (range: 3.2 to 9.8 cm). There were 4 chronic totally occlusion and 7 severe stenosis. All patients underwent the operation successfully. The technical success rate was 10/11. Bailout stenting was performed in one lesion because of flow-limiting dissection. Four lesions were grade 3 to 4 in peripheral artery calcium score system, and 9 lesions with calcification arc≥180°. Larger diameter drug-coated balloons were selected in 5 lesions after measurement of intravascular ultrasound. The follow-up time was (6.0±1.9) months (range: 3 to 9 months). The ankle-brachial index of the patient was significantly improved immediately after surgery (0.97±0.13 vs. 0.48±0.18, t=-7.60, P<0.01) and at 3 months after surgery (0.95±0.12 vs. 0.48±0.18, t=-7.17, P<0.01). The 3-month primary patency rate was 11/11, the target lesion reintervention was 0 and ulcer healing rate was 3/4. Conclusion: IVUS assisted ELA in the treatment of lower limb artery lesions is safe and effective in early stage.

ABSTRACT

The stability of internal fixation of femoral neck fractures can be obtained through surgical techniques, the configuration of screws and bone grafting, etc. However, the blood supply injury caused by fractures could not be completely reversed by the current medical management. Hence, the comprehensive evaluation of the residual blood supply of the femoral neck, to perioperatively avoid further iatrogenic injury, has become a hotspot. The anatomy of the extraosseous blood supply of the femoral neck has been widely reported, while its clinical application mostly involved the assessment of the medial circumflex femoral artery and retinacular arteries. However, further studies are needed to explore the prognosis of patients with these artery injuries, with different degrees, caused by femoral neck fractures. Direct observations of nutrient foramina in vivo are not possible with current clinical technologies, but it is possible to make reasonable preoperative planning to avoid subsequent femoral head necrosis based on the distribution features of nutrient foramina. The anatomy and clinical application studies of the intraosseous blood supply focused on the junction area of the femoral head and neck to probe the mechanism of femoral head necrosis. Thus, the intraosseous blood supply of other regions in the femoral neck remains to be further investigated. In addition, a blood supply evaluation system based on a three-level structure, extraosseous blood vessels, nutrient foramina, and intraosseous vascular network, could be explored to assist in the treatment of femoral neck fractures.

ABSTRACT

OBJECTIVE@#To evaluate the effectiveness and safety of Rotarex catheter system in treating femoropopliteal artery stenosis accompanied with thrombosis.@*METHODS@#From Jun. 2017 to Dec. 2019, the clinical data of 32 femoropopliteal artery stenosis accompanied with thrombosis cases treated with Rotarex catheter system were retrospectively analyzed. There were 23 males and 9 females aged from 50 to 89 years and the mean age was (70.7±10.3) years. Six cases had acute course of disease (≤2 weeks), 17 cases had subacute course of disease (>2 weeks, ≤3 months), and 9 cases had chronic course of disease (>3 months). Mean lesion length was (23.4±13.7) cm, mean occlusion length was (19.9±13.3) cm, and in-stent occlusion 7 cases. The superficial femoral artery (SFA) was involved in 13 cases, the popliteal artery (PA) was involved in 8 cases, and both SFA and PA were involved in the other 11 cases. All the cases were treated with Rotarex catheter system. When necessary, suction with large lumen catheter was enabled. Residual stenosis was treated with percutaneous transluminal angioplasty (PTA). Drug-coated balloon (DCB) was only used in patients with financial status, and stent was used only when it was necessary. Heparin was used for 24 h after procedures, and after that, antiplatelet agents were used. Doppler ultrasonography was taken during the followed-up.@*RESULTS@#Technical success was 100%, and mean procedure time was (107.4±21.5) min. 8F (1F≈0.33 mm) and 6F Rotarex catheter were used in 27 and 5 cases respectively. In 27 cases, forward flow was obtained immediately after debulking with Rotarex catheter, and in the other 5 cases, suction with large lumen catheters were used. PTA was used in all 32 cases. DCB were used in 8 cases, of which 4 were used in in-stent stenosis. Twelve cases were implanted stents. There were no perioperative deaths. The only one procedure related complication was distal embolism. We took out the thrombus with guiding catheter. In all cases, mean hospital stay were (4.6±1.5) d. The ankle brachial index increased from 0.32±0.15 to 0.86±0.10 after treatment (t=-16.847, P < 0.001). The Rutherford stages decreased significantly (Z=-4.518, P < 0.001). All the patients were followed up for 6.0-36.0 months, and the median time was 16.0 months. 2 cases stopped antiplatelet agents, which resulted in acute thrombosis. Another percutaneous mechanical thrombectomy and PTA were taken in one of them. Two cases died of cardiovascular disease during the follow-up, and no amputation was observed. Target lesion restenosis occurred in 7 cases during the follow-up, and target lesion revascularization (TLR) was taken in two of them.@*CONCLUSION@#In treating femoropopliteal artery stenosis accompanied with thrombosis, Rotarex catheter can remove thrombus effectively, and that can expose underlying lesions and reduce stent use and complications rates. It is a safe and effective method.

ABSTRACT

Los aneurismas femorales son raros y más aún en la arteria femoral superficial. Estos representan solo el 3 por ciento de todos los aneurismas periféricos. El objetivo de este trabajo fue presentar el caso de un aneurisma verdadero aislado en arteria femoral superficial asociado a síndrome del dedo azul. Se reporta un paciente masculino de 75 años, fumador, con antecedentes patológicos personales de hipertensión arterial, que llega remitido con urgencia desde su área de salud por presentar cambios de coloración (cianosis), frialdad y dolor en la planta y los dedos del pie derecho (microembolias distales). En la tomografía computarizada contrastada se observó aneurisma aislado en la arteria femoral superficial de 4,5 cm de diámetro transversal. Se decidió operar al paciente y se realizó aneurismectomía con interposición de injerto protésico con politetrafluoroetileno, con una configuración de anastomosis término-terminal. Tuvo una evolución clínica posoperatoria inmediata y tardía satisfactoria. Entre los aneurismas femorales, los que afectan a la arteria femoral superficial están menos descritos y pueden complicarse con trombosis, embolización distal o rotura. Existe un alto consenso para su reparación, al eliminar la fuente embólica, prevenir la trombosis, tratar la rotura, eliminar cualquier efecto de masa y restaurar la perfusión de la extremidad distal. Dado que el síndrome del dedo azul puede ser la primera manifestación de esta enfermedad, su rápido reconocimiento, diagnóstico precoz de la fuente embolígena y tratamiento médico-quirúrgico pueden evitar la amputación mayor o la muerte del paciente(AU)


Femoral aneurysms are rare and even more so in the superficial femoral artery. These account for only 3 percent of all peripheral aneurysms. The objective of this study was to present the case of an true isolated aneurysm in the superficial femoral artery associated with blue finger syndrome. A 75-year-old male patient, smoker, with a personal pathological history of arterial hypertension, is reported to be urgently referred from his health area for presenting changes in coloration (cyanosis), coldness and pain in the sole and toes of the right foot (distal microembolisms). The contrasted computed tomography showed an isolated aneurysm in the superficial femoral artery of 4.5 cm transverse diameter. It was decided to operate on the patient and aneurysmectomy was performed with interposition of prosthetic graft with polytetrafluoroethylene, with a configuration of termino-terminal anastomosis. He had a satisfactory immediate and late postoperative clinical evolution. Among femoral aneurysms, those affecting the superficial femoral artery are less described and can be complicated by thrombosis, distal embolization, or rupture. There is a high consensus for their repair by removing the embolic source, preventing thrombosis, treating rupture, eliminating any mass effects and restoring perfusion of the distal limb. Since blue finger syndrome may be the first manifestation of this pathology, its rapid recognition, early diagnosis of the emboligenic source and medical-surgical treatment can prevent major amputation or death of the patient(AU)

ABSTRACT

Objective: To examine the effective and safe outcomes of drug-coated balloon (DCB) angioplasty for the treatment of femoropopliteal long lesions in mid-term and long-term follow-up. Methods: The clinical data of 114 patients with symptomatic (Rutherford 2 to 6) femoropopliteal long lesions who underwent angioplasty with DCB between June 2016 and May 2021 at Department of Vascular Surgery,Beijing Tsinghua Changgung Hospital were retrospectively analyzed. A total of 75 males and 39 females were enrolled, aged (71.9±8.4)years (range: 49 to 89 years). Among 138 lesions in 114 patients, there were 111 de nove lesions (80.4%, 111/138). Total occlusions were recanalized in 116 limbs (84.1%, 116/138). The lesion length was (280.9±78.7)mm (range: 150 to 520 mm). DCB angioplasty combined with debulking devices was used in 59 lesions (42.8%, 59/138).The bail-out stent implantation was performed in 27 limbs (19.6%, 27/138). The Kaplan-Meier method was used to evaluate cumulative primary patency rate, freedom from the clinically driven target lesion revascularization (CD-TLR) rate and accumulate survival rate. Univariate and multivariate analyses with Cox proportional hazards models were performed to determine the significant prognostic factors for primary patency. Results: DCB angioplasty was completed in 114 patients. The technical success rate was 98.2%(112/114). The mean follow-up time was 18 months (range: 3 to 54 months).The results showed that primary patency rates at 12, 24 and 36 months postoperatively were 87.5%, 75.2% and 55.1%, respectively. Freedom from CD-TLR rate at 12, 24 and 36 months postoperatively were 92.4%, 81.8% and 68.7%, respectively. Accumulate survival rate at 12, 24 and 36 months postoperatively were 96.2%, 94.0% and 80.2%. Multivariate Cox's regression analyses showed that chronic limb-threatening ischemia(CLTI) (HR=2.629, 95%CI:1.519 to 4.547, P<0.01) and hyperlipidemia (HR=2.228, 95%CI: 1.004 to 4.948, P=0.026) were independent prognosis factors for primary patency in DCB treatment of femoropopliteal long lesions. Conclusions: DCB provided favorable outcomes for the treatment of femoropopliteal long lesions. CLTI and hyperlipidemia are independent prognosis factors for restenosis after DCB angioplasty.

ABSTRACT

Objective: To analyze the treatment and clinical prognosis of lower extremity arterial injury caused by trauma. Methods: The clinical data of 77 patients with traumatic lower extremity arterial injury admitted to Department of Vascular Surgery,Yichang Central People's Hospital from January 2013 to June 2021 were collected retrospectively. There were 65 males and 12 females, with an average age of 47.4 years (range: 7 to 75 years). Among the 77 patients, 56 cases (72.7%) had open injury and 21 cases (27.3%) had closed injury. Iliac artery was injured in 9 cases (11.7%), common femoral artery in 7 cases (9.1%), superficial femoral artery in 1 case (1.3%), popliteal artery in 11 cases (14.3%) and inferior knee artery in 49 cases (63.6%). The treatment methods and clinical effects were analyzed. Results: One case with pelvic fracture combined the internal iliac artery injury and 1 case with multiple injuries involving the common femoral artery died of circulatory failure before surgery. Seventy-five cases received vascular-related operations, including arterial ligation in 24 cases, arterial reconstruction in 40 cases, stent graft implantation in 1 case, primary amputation in 2 cases, and arterial embolization in 8 cases. The overall mortality rate was 6.5% (5/77), all of which were closed injuries. Except for 2 cases who died before surgery, 3 cases with pelvic fracture combined the internal iliac artery injury died of multiple organ failure after internal iliac artery embolization. There were 8 cases received amputation (10.4%, 8/77), 5 cases with closed injury and 3 cases with open injury. In addition to 2 cases with primary amputation, 6 cases underwent secondary amputation due to ischemia-reperfusion injury after revascularization (4 cases with popliteal artery injury and 2 cases with subpatellar artery injury). The average followed-up time was 17 months (range: 2 months to 8 years). One patient with femoral artery injury underwent autologous great saphenous vein bypass, and lower limb artery CT angiography was re-examined 6 months after the operation, and 30% distal anastomotic stenosis was found. Ankle brachial index<0.8 was found in two patients 1 year after popliteal artery repair, but none of the patients had intermittent claudication symptoms, and no further intervention was performed. Five patients suffered delayed healing due to severe lower limb injury, fracture and skin injury. Among them, 2 cases had poor wound healing at the stump of amputation, which gradually healed 3 to 5 months after several debridements. The other 3 vascular injury combined with tibial fracture patients had delayed tibial healing after surgery, but no symptoms of vascular ischemia occurred. All the other patients recovered well and no other serious complications occurred. Conclusions: The proportion of death and disability in patients with lower limb artery injury caused by trauma is high. Active and orderly surgical repair according to the site and type of injury can reduce the mortality, save the function of the affected limb, and promote the healing of injury.

ABSTRACT

Objective: To summarize the single center experience of transcatheter aortic valve replacement (TAVR) with a simplified operative protocol. Methods: Consecutive patients who underwent transfemoral TAVR (TF-TAVR) from July 2020 to December 2020 in Fuwai Hospital were retrospectively analyzed. We compared the baseline characteristic, procedure information, 30-day follow-up outcomes of the patients who underwent TF-TAVR without the simplified operative protocol (routine group) or with the simplified operative protocol (simplified protocol group). Results: 93 patients were collected, 42 patients belonging to routine group, 51 patients belonging to simplified protocol group. In simplified protocol group, there were 51 patients planned to use ultrasound-guided femoral access puncture, procedure was successful in all 51 patients (100%). There were 49 patients planned to use the radial artery as the secondary access, procedure was successful in 45 patients (92%). There were 48 patients planned to use the strategy of avoidance of urinary catheter, this strategy was achieved in 35 patients (73%). There were 12 patients planned to use the left ventricular guidewire to pace, procedure was successful in 11 patients (92%). There were no differences in baseline characteristics, major clinical endpoints and 30-day follow-up outcomes between the two groups. Meanwhile, the procedure time ((62.5±17.9)min vs. (78.3±16.7)min, P<0.001), operation room time ((133.7±25.1)min vs. (159.2±42.6)min, P<0.001), X-ray exposure time ((17.2±6.5)min vs. (20.2±7.7)min, P=0.027) were significantly shorten in simplified protocol group compared with the routine group. Conclusion: Our study results indicate that the simplified operative protocol of TF-TAVR is as effective and safe as the routine operative protocol, meanwhile using the simplified operative protocol can significantly increase the operative efficiency of TF-TAVR.

ABSTRACT

Introducción: Se presenta un caso clínico de seudoaneurisma de la arteria femoral circunfleja lateral secundario a una fractura pertrocantérica de cadera. Materiales y métodos: Como el cuadro y su localización son infrecuentes, se llevó a cabo una revisión bibliográfica sistematizada que incluyó todos los casos publicados sobre esta enfermedad (n = 40) en los últimos 15 años. Resultados: No se hallaron asociaciones estadísticamente significativas entre ninguna de las variables estudiadas. Sin embargo, parece existir cierto consenso en mantener una alta sospecha clínica para una intervención precoz y así obtener mejores resultados. Tanto su etiología como su localización se relacionan con la morfología de la fractura, el gesto quirúrgico y el material de osteosíntesis. Asimismo, hay una tendencia mayor a utilizar la angiotomografía para el diagnóstico y la localización del seudoaneurisma. Conclusiones: Nuestra paciente es el primer caso de resolución espontánea. Es fundamental conocer esta complicación tan poco frecuente para optimizar los resultados terapéuticos. Esta revisión, la más reciente sobre el tema, es muy útil para enumerar y subrayar los aspectos más importantes sobre el manejo y la prevención de los seudoaneurismas secundarios a una fractura de cadera. Nivel de Evidencia: IV


Introduction: We present a case of a lateral circumflex femoral artery pseudoaneurysm associated with pertrochanteric hip fracture. Materials and methods: We performed a systematic review considering all cases published in the last 15 years about this pathology (n=40). Results: No statistically significant associations were found between any of the variables studied. However, there seems to be some consensus in maintaining a high clinical suspicion for early intervention, thus obtaining better outcomes. Both its etiology and location are related to the morphology of the fracture, the surgical procedure, and the osteosynthesis material. Likewise, there is a greater tendency to use CT angiography for the diagnosis and localization of the pseudoaneurysm. Conclusion: Our patient is the first reported case of spontaneous resolution. Knowing this rare complication is essential to optimize therapeutic results. This review, the most recent on the subject, is very useful in listing and highlighting the most important aspects of the management and prevention of pseudoaneurysms secondary to hip fracture. Level of Evidence: IV

ABSTRACT

Resumo A artéria femoral profunda, devido às suas características anatômicas, se encontra protegida da maioria dos traumatismos vasculares. Relatamos um caso de pseudoaneurisma de ramo perfurante da artéria femoral profunda, associado à fístula arteriovenosa, secundário a rotura completa do músculo vasto medial em paciente jogador de futebol. A ressonância magnética demonstrou lesão muscular associada a pseudoaneurisma, e a angiotomografia confirmou a presença de pseudoaneurisma associado a fístula arteriovenosa de ramo da artéria femoral profunda. Foi realizado tratamento endovascular da fístula através da embolização com micromolas fibradas e drenagem cirúrgica do hematoma muscular. O paciente evoluiu bem, sem queixas clínicas no 30º dia de pós-operatório e também após 1 ano.


Abstract Due to its anatomical characteristics, the deep femoral artery is protected from most vascular injuries. We report a case of a soccer player with pseudoaneurysm of a perforating branch of the deep femoral artery, associated with an arteriovenous fistula and secondary to complete rupture of the vastus medialis muscle. Magnetic resonance imaging showed muscle damage associated with a pseudoaneurysm and angiotomography confirmed the presence of a pseudoaneurysm associated with a deep arteriovenous fistula of a branch of the deep femoral artery. Endovascular treatment of the fistula was performed by embolization with fibrous microcoils and surgical drainage of the muscle hematoma. The patient recovered well, was free from clinical complaints on the 30th postoperative day and also after 1 year.

ABSTRACT

Abstract Co-occurrence of acute limb ischemia (ALI) and arteriovenous fistula (AVF) as a manifestation of inadvertent arterial injury during percutaneous femoral vein dialysis catheter insertion is a rare and dangerous, but preventable complication. Iatrogenic femoral AVF commonly presents late, with leg swelling or high output cardiac failure. However, the co-occurrence of a femoral AVF with both progressive leg swelling, and acute thromboembolism has not been previously reported. We report the case of an iatrogenic femoral AVF with superficial femoral artery (SFA) thrombosis and distal embolism in a 53-year-old female who underwent percutaneous femoral access for temporary hemodialysis. Both the SFA and AVF were managed with open surgical repair.


Resumo A coocorrência de isquemia aguda de membro (IAM) e fístula arteriovenosa (FAV) como uma manifestação de lesão arterial inadvertida durante a inserção de cateter para hemodiálise por via femoral percutânea é uma complicação rara e perigosa, porém evitável. A FAV femoral iatrogênica geralmente tem apresentação tardia, com edema dos membros inferiores ou insuficiência cardíaca de alto débito. No entanto, a coocorrência de FAV femoral com edema progressivo dos membros inferiores e tromboembolismo agudo não foi previamente relatada. Relatamos o caso de uma FAV femoral iatrogênica com trombose da artéria femoral superficial (AFS) e embolia distal em uma paciente do sexo feminino, 53 anos, submetida à acesso femoral percutâneo para hemodiálise temporária. Tanto a AFS quanto a FAV foram manejadas com reparo cirúrgico aberto.

ABSTRACT

El pseudoaneurisma se puede definir como un hematoma pulsátil repermeabilizado y encapsulado, en comunicación con la luz de un vaso dañado. Los pseudoaneurismas de las extremidades son los más frecuentes; entre ellos se destacan los iatrogénicos de la arteria femoral. Su incidencia es del 2 por ciento-8 por ciento cuando se realizan angioplastia/stent coronarios y del 0,2 por ciento-0,5 por ciento cuando únicamente se hace angiografía diagnóstica. Se presenta un paciente con diagnóstico de pseudoaneurisma femoral derecho posterior a un cateterismo cardíaco, con el objetivo de demostrar la importancia del diagnóstico temprano de las pseudaeurismas para el tratamiento quirúrgico oportuno y evitar complicaciones posteriores. Al mes del procedimiento, el paciente comenzó con aumento de volumen en la región inguinal derecha y a la auscultación se apreció un soplo a ese nivel. Se le realizó exérisis del pseudoaneurisma y reparación quirúrgica de la arteria femoral. En las consultas de evaluación posoperatoria se mostró una evolución clínica y radiológica satisfactoria. El diagnóstico rápido de estas entidades vasculares evita que se presenten complicaciones posteriores y aseguran una evolución rápida y satisfactoria de los pacientes que la padecen(AU)


Pseudoaneurysm can be defined as a repermeabilized and encapsulated pulsatile hematoma, in communication with the light of a damaged vessel. Pseudoaneurysms of the limbs are the most frequent; among them are the iatrogenic of the femoral artery. Its incidence is 2 percent -8 percent when coronary angioplasty/stent is performed and 0.2 percent-0.5 percent when only diagnostic angiography is performed. A patient with a diagnosis of right femoral pseudoaneurysm after cardiac catheterization is presented, with the aim of demonstrating the importance of early diagnosis of pseudoaneurysms for timely surgical treatment and avoiding subsequent complications. A month after the procedure, the patient began with an increase in volume in the right inguinal region and auscultation showed a murmur at that level. Pseudoaneurysm exeresis and surgical repair of the femoral artery were performed. In the postoperative evaluation consultations, a satisfactory clinical and radiological evolution was shown. The rapid diagnosis of these vascular entities prevents subsequent complications from occurring and ensures a rapid and satisfactory evolution of patients who suffer from it(AU)

ABSTRACT

Hyperbaric Oxygen Therapy (HBOT) assumes that high pressure hyperoxygenation causes faster tissue recovery and wound healing. Lower extremity flow rates are affected by leg ulcers that change vasodilation, microcirculation resistance, and local tissue demands; how blood hyper oxygenation influences these factors is still unclear. Peripheral arterial occlusive disease (PAOD) has been mostly associated with HBOT results in the femoral artery than in other arteries. Common femoral artery (CFA) peak systolic velocities (PSV), measured pre and post HBOT, were analyzed to research HBOT hemodynamics. Sixteen patients with leg ulcers who were 65 ± 11 (SD) (38-87) years-old, had HBOT of 90 minutes at 2.6 ATA. Bilateral CFA Doppler velocity waveforms were recorded immediately pre and post HBOT. Ulcerated vs non-ulcerated peak systolic velocity (PSV) data were compared using paired t-test. CFA PSV were significantly equal in the ulcerated and non-ulcerated extremities before HBOT: 114 ± 35 (SD) cm/s vs 116 ± 41 cm/s (p = 0.87 by paired t-test). CFA PSV in the ulcerated extremity increased to 122 ± 35 cm/s after HBOT but were statistically insignificant (p =.19 by one-tailed paired t-test). On the other hand, CFA PSV decreased to 103 ± 28 cm/s (p =.049 by one-tailed paired t-test) in the non-ulcerated extremity and were significantly lower after HBOT, with 103 ± 28 cm/s vs 122 ± 35 cm/s for the ulcerated limb (p =.02 by paired t-test). Blood velocity responses post HBOT showed differences between ulcerated vs non-ulcerated extremities. The non-ulcerated extremity apparently responded to oxygenation more than the ulcerated extremity. Such observation suggests further research on hemodynamic reactions caused by HBOT.


A oxigenoterapia hiperbárica (HbOT) assume que a oxigenação de alta pressão resulta em mais celeridade na recuperação do tecido e na cicatrização de feridas. As taxas de fluxo nas extremidades inferiores são afetadas por úlceras nas pernas que alteram a vasodilatação, a resistência da microcirculação e as demandas locais de tecido; esses fatores podem ser influenciados pela hiperoxigenação sanguínea de maneiras ainda não claramente compreendidas. A doença arterial oclusiva periférica femoral (DAOP) tem sido associada a melhores resultados de HBOT quando comparada a outras artérias. As velocidades sistólicas de pico (PSV) da artéria femoral comum (CFA) medidas antes e depois da HBOT foram analisadas como parte de um projeto de pesquisa da hemodinâmica da HBOT. Dezesseis pacientes com úlceras de perna, com idade 65 ± 11 (DP), 38-87 anos, realizaram HBOT com duração de 90 minutos a 2,6 ATA. As formas de onda de velocidade do Doppler CFA bilateral foram registradas imediatamente antes e depois da HBOT. Os dados de PSV ulcerado vs. não ulcerado foram comparados usando o teste t pareado. Pre HBOT CFA PSV não foi significativamente diferente nas extremidades ulceradas e não ulceradas: 114 ± 35 (DP) cm/s vs 116 ± 41 cm/s (p = 0,87 pelo teste t pareado). O PSV pós HbOT CFA na extremidade ulcerada aumentou para 122 ± 35 cm/s, mas não atingiu significância estatística (p = 0,19 pelo teste t pareado unicaudal). Em contraste, CFA PSV na extremidade não ulcerada diminuiu para 103 ± 28 cm/s (p = 0,049 pelo teste t pareado unicaudal). O pós-HbOT CFA PSV foi significativamente menor no membro não ulcerado, 103 ± 28 cm/s vs 122 ± 35 cm/s para o membro ulcerado (p = 0,02 pelo teste t pareado). As respostas da velocidade do sangue após HbOT mostraram diferenças entre as extremidades ulceradas e não ulceradas. Aparentemente, a extremidade não ulcerada respondeu mais significativamente à oxigenação do que a extremidade ulcerada. Tal observação sugere pesquisas adicionais sobre as reações hemodinâmicas decorrentes da HbOT.


La terapia de oxígeno hiperbárico (HbOT) asume que la hiperoxigenación a alta presión da como resultado una recuperación más rápida de los tejidos y una cicatrización de heridas. Las tasas de flujo de las extremidades inferiores se ven afectadas por úlceras en las piernas que alteran la vasodilatación, la resistencia de la microcirculación y las demandas de los tejidos locales; estos factores pueden verse influenciados por la hiperoxigenación de la sangre, de formas que aún no se han entendido con claridad. La enfermedad oclusiva arterial periférica femoral (PAOD) se ha relacionado con los mejores resultados de HbOT que otras arterias. Las velocidades sistólicas máximas (PSV) de la arteria femoral común (CFA) medidas antes y después de la HbOT se analizaron como parte de un proyecto para investigar la hemodinámica de la HbOT. Dieciséis pacientes con úlceras en pierna, 65 ± 11 (DE) (38-87) años, 12 hombres, 11 diabéticos, tenían HbOT de 90 minutos a 2,6 ATA. Se registraron formas de onda de velocidad de CFA Doppler bilaterales inmediatamente antes y después de la HbOT. Se compararon los datos de la velocidad sistólica máxima (PSV) ulcerada frente a la no ulcerada mediante la prueba t pareada. Pre HbOT CFA PSV no fue significativamente diferente en las extremidades ulceradas y no ulceradas: 114 ± 35 (DE) cm/s vs 116 ± 41 cm/s (p = 0,87 por prueba t pareada). Post HbOT CFA PSV en la extremidad ulcerada aumentó a 122 ± 35 cm/s pero no alcanzó significación estadística (p =.19 por prueba t unilateral pareada). En contraste, CFA PSV en la extremidad no ulcerada disminuyó a 103 ± 28 cm/s (p =.049 por prueba t unilateral pareada). El PSV después de la HbOT CFA fue significativamente menor en la extremidad no ulcerada, 103 ± 28 cm/s frente a 122 ± 35 cm/s para la extremidad ulcerada (p = 0,02 según la prueba t pareada). Las respuestas de velocidad sanguínea post HbOT mostraron diferencias entre las extremidades ulceradas y no ulceradas. Aparentemente, la extremidad no ulcerada respondió más significativamente a la oxigenación que la extremidad ulcerada. Tal observación sugiere una mayor investigación sobre las reacciones hemodinámicas debidas a la HbOT.

ABSTRACT

SUMMARY OBJECTIVE: The objective of this study was to compare the interventions of percutaneous transluminal drug-coated balloon angioplasty (DCB PTA) and standard PTA in the treatment of patients with the below-the-knee peripheral artery disease (BTK PAD). METHODS: Overall, 196 patients (113 males and 83 females; mean age: 63.56±11.94 years; 45-83 years) were treated with PTA for BTK PAD between June 2014 and March 2019. RESULT: Standard PTA (group 1; 96 patients) and DCB PTA (group 2; 100 patients) results were analyzed and compared retrospectively. No statistically significant difference was found between the mean ages of group 1 and 2 patients (p=0.371, p>0.05). Demographic and clinical data were compared and no any statistically significant differences was found between the two groups. Comparing in terms of the iliac lesion, there was no statistically significant difference between the two groups. However, a statistically significant difference was found between the two groups in terms of frequency of popliteal lesions (p=0.001; p<0.05). There was not a statistically significant difference between the two groups in terms of other lesions. In addition, limb salvage rates were 82.0% (18 amputations) and 65.6% (33 amputations) in the drug-release balloon group and the naked balloon group, at the end of 1 year, respectively. No distal embolism, limb-threatening ischemia, and mortality were observed in any patients. CONCLUSIONS: Based on this study, patients in the DCB group had significantly higher rates of primary patency as compared with the other patients.

ABSTRACT

Introducción: La arteria femoral común y sus ramas suministran la mayor parte del flujo sanguíneo al muslo, así como a la totalidad de la pierna y el pie, lo que da lugar a la mayor rama del triángulo femoral: la arteria femoral profunda. Objetivo: Exponer la efectividad de la profundaplastia femoral en la "era endovascular". Reporte del caso: Se presenta un caso de enfermedad arterial periférica de múltiples sectores, sin criterio de cirugía revascularizadora (derivación protésica aorto bifemoral). El paciente manifestaba claudicación intermitente a menos de 30 metros, localizada en pantorrilla derecha. En el estudio hemodinámico se apreciaron los índices de presiones tobillo/brazo disminuidos en arteria tibial posterior (0,46) y pedia derecha (0,33). La ecografía doppler del sector femoral derecho evidenció una estenosis de la arteria femoral profunda en su origen, que producía aumento de las velocidades picos sistólicos (479 cm/s), con flujo desorganizado, dilatación posestenótica y oclusión de la arteria femoral superficial en su origen. Se realizó endarterectomía femoral común y profunda con colocación de parche de politetrafloroetileno. El paciente evolucionó sin complicaciones posoperatorias. En el seguimiento se observó mejoría clínica en relación con la distancia de claudicación y un aumento de los índices de presiones tobillo/brazo en arteria tibial posterior y pedia derecha (0,50), respectivamente. Conclusiones: La profundaplastia femoral, aún en la "era endovascular", permanece como un proceder eficaz que resulta alternativa de tratamiento revascularizador en la enfermedad arterial periférica de localización infrainguinal(AU)


Introduction: The normal femoral artery and its branches supply most of the blood flow to the thigh, as well as to the whole leg and foot, which forms the largest branch of the femoral triangle: the deep femoral artery. Objective: Show the effectiveness of femoral deep plasty in the "endovascular era". Case report: It is presented a case of peripheral artery disease in multiple sectors, without surgical criteria of revascularization (derivación protésica aortobifemoral). The patient presented intermittent claudication in less than 30 meters, and it was located in the right calf. In the hemodynamic study, the ankle-arm pressure indexes were dicreased in the posterior tibial artery (0,46) and right dorsalis pedis artery (0,33). The doppler echocardiography of the right femoral sector confirmed a stenosis in the deep femoral artery in its origin, which produced an increase in the peak systolic velocity (479 cm/s), unorganized flows, poststenotic dilatation and occlusion of the superficial femoral artery in its origin. It was performed a common and deep femoral endarterectomy with colocation of polytetrafluoroethylene patch. The patient evolved without post-surgical complications. In the follow-up, it was observed a clinical improvement in relation with the claudication distance and the increase of the ankle-arm pressure indexes in the posterior tibial artery and right dorsalis pedis artery (0,50), respectively. Conclusions: The femoral deep plasty, still in the ´´endovascular era´´, is an efficient procedure that is an alternative to the revascularization treatment in the peripheral artery disease with infrainguinal location(AU)

ABSTRACT

Abstract With transcatheter aortic valve implantation (TAVI) technology expanding its indications for low-risk patients, the number of TAVI-eligible patients will globally grow, requiring a better understanding about the second-best access choice. Regarding the potential access sites, the transfemoral retrograde route is recognized as the standard approach and first choice according to current guidelines. However, this approach is not suitable in up to 10-15% of patients, for whom an alternative non-femoral access is required. Among the alternative non-femoral routes, the transaxillary approach has received increasing recognition due to its proximity and relatively straight course from the axillary artery to the aortic annulus, which provides a more accurate device deployment. Here we discuss some particular aspects of the transaxillary access, either percutaneously performed or by cutdown dissection.

ABSTRACT

RESUMEN El pseudoaneurisma es aquel hematoma pulsátil y encapsulado producido tras la rotura de todas las túnicas del vaso y contenido por tejidos vecinos circundantes. Es considerado una complicación tardía en la cirugía protésica aorto-ilíaca. Se presenta un paciente de 72 años al que se le realizó un baipás aorto-bifemoral 13 años atrás, y que posteriormente se le diagnosticó un pseudoaneurisma para-anastomótico que se dejó evolucionar por presentar varias comorbilidades asociadas. Transcurridos 2 años fue necesario realizarle una intervención quirúrgica por presentar crecimiento excesivo de la tumefacción y complicación isquémica con necrosis cutánea. La aparición de un pseudoaneurisma está relacionada con el sexo, el material protésico y con el tiempo que transcurre desde la cirugía. El seguimiento ultrasonográfico durante el postoperatorio es primordial para identificar tempranamente esta complicación.


ABSTRACT Pseudoaneurysm is that pulsatile and encapsulated hematoma produced after the rupture of all vessel layers and contained by surrounding neighboring tissues. It is considered a late complication in aorto-iliac prosthetic surgery. We present a 72-year-old patient who underwent an aorto-bifemoral bypass grafting 13 years ago, and who was subsequently diagnosed with a para-anastomotic pseudoaneurysm that was allowed to evolve due to presenting several associated comorbidities. After two years, it was necessary to perform a surgical intervention due to the excessive growth of the swelling, and ischemic complication with skin necrosis. The appearance of a pseudoaneurysm is related to sex, prosthetic material as well as the time that elapses since the surgery. Ultrasound follow-up during the postoperative period is essential for an early identification of this complication.

Aim: The aim of this paper is to present a case of a deep femoral artery pseudoaneurysm secondary to a penetrating trauma in the left thigh, its management and a literature review. Clinical Case: 21-year-old male referred to the emergency department of our institution 5 months after he was injured with a knife on his left thigh, with severe local swelling, local pain, and difficulty to the mobilization of the left leg. A 2.3 cm x 2.1 cm x 2.7 cm deep femoral artery pseudoaneurysm was diagnosed with a 13.5 cm x 12.6 cm x 23 cm adjacent hematoma. Endovascular exclusion was made with coils and evacuation of the hematoma with open surgery. Results: The patient was discharged on the third day postop without pain and walking with antibiotics and follow-up to a month did not reveal any complications. Discusion and Conclusion: Exclusion with coils is an adequate management in deep femoral pseudoaneurysms that facilitates the evacuation of the hematoma lowering the risk of bleeding.

ABSTRACT

OBJECTIVE@#To evaluate the role of Rotarex mechanical thrombectomy system in treating instent restenosis of peripheral artery disease (PAD).@*METHODS@#The clinical data of 7 in-stent restenosis (ISR) cases of lower extremity PAD from June 2017 to Dec 2018 were retrospectively analyzed. There were 5 males and 2 females and the mean age was (70.0±7.6) years from 59.0 to 76.0 years. All the cases were treated by Rotarex mechanical thrombectomy system. In the 7 cases, time interval from the previous stent implantation to ischemia recurrence was 1.0 to 72.0 months, and the median time was 6.0 months. The period from ischemia recurrence to endovascular therapy was 3 days to 2 years, and the median time was 62 days. Rotarex mechanical debulking catheter and percutaneous transluminal angioplasty (PTA) were used in all the cases, and the stent was used only when it was necessary. Anticoagulation was used for 24 hours after procedures and then antiplatelet agents were used as usual. Doppler ultrasonography was taken during the followed-up.@*RESULTS@#All the 7 cases were successful in technology, 3 of which were implanted with new stents for the fracture of the old ones. while for the other four cases, no new stent was implanted. The ankle-brachial index (ABI) increased from 0.31±0.08 to 0.86±0.08 after treatment (t=-12.84, P < 0.001). Thrombectomy was applied urgently in one case because of acute thrombosis in the stent, and the result was good. There was no other complications in hospital. All the patients were followed up for 5.0-22.0 months, and the median time was 14.0 months. No death and amputation occurred during the follow-up. One patient stopped antiplatelet agents because of gastrointestinal bleeding, which resulted in acute thrombosis. in-stent restenosis reappeared in 3 cases.@*CONCLUSION@#Debulking using Rotarex catheter is safe and effective in treating in-stent restenosis of PAD, especially in reducing stents implantation, but is not good at dealing with old thrombus and proliferating intima, and can do nothing about fractured stents and hyperplasia of intima, so it needs to be combined with stents and drug coated balloons.

ABSTRACT

Objective: To analyse the clinical application of thoracodorsal artery perforator flaps (TDAPF) in the repair of head and neck defects. Methods: A retrospective review was conducted on 38 patients with oral and maxillofacial head and neck malignant tumors who underwent radical resection of oral and oropharyngeal carcinoma and TDAPF repair in the Department of Oral and Maxillofacial Head and Neck Oncology of the Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from June 2017 to November 2018. Among them, 32 were males and 6 were females, aged 30-74 years. Flap size, vessel pedicle length, diameter and number of perforators, and flap fat thickness were recorded and counted. Elasti Meter and Skin Fibro Meter were applied to measure the skin elasticity and hardness in the donor areas of 4 kinds of skin flaps before the flap preparation. SPSS 19.0 statistical software was used for statistical analysis of the data. Results: All the flaps survived (100%). The mean elasticity of TDAPF [(41.2±12.9) N/m] was significantly lower than that of anterolateral thigh [(77.6±23.3) N/m, χ²=88.89, P<0.05], anterolateral thigh [(62.6±17.7) N/m, χ²=59.99, P<0.05] and or forearm flap [(51.7±8.6) N/m, χ²=37.82, P<0.05]. The hardness of TDAPF [(0.037±0.016) N] was also significantly lower than that of anterolateral femoral [(0.088±0.019) N, F=93.27, P<0.05], anteromedial femoral [(0.059±0.020) N, F=25.71, P<0.05] or forearm flap [(0.062±0.016) N, F=29.11, P<0.05]. Follow-up period ranged from 2 to 14 months. The 38 patients treated with TDAPF had a good recovery of the functions in the recipient areas, and the scars of the donor areas were not obvious after surgery, without serious complications. Conclusion: TDAPF is suitable for reconstruction of head and neck defect, with ductile texture and good recovery of the morphology and function of head and neck.
