Surgical management of torsion of ovarian fibroma: a case report

Ovarian fibromas are solid tumors that belong to sex-cord stromal cell tumors of the ovary and are composed of fibrous tissue. They are the most common benign solid tumors of the ovary. The clinical presentation is variable and can include abdominal pain, bloating and menstrual irregularities. In some cases, the first presentation can be that of torsion. This case report presents a case of a 28-year-old who presented with features suggestive of ovarian torsion. Diagnostic difficulty was faced due to the complex appearance of the mass and presenting age of the patient. However, the Computed Tomography (CT) reported a large 12cm multiloculated cystic lesion likely ovarian in origin. Our patient underwent a laparotomy successfully. The diagnosis was confirmed by histopathology.

Role of ultrasonography in evaluation of right iliac fossa mass compared to CT scan

Background: With the demonstration of origin and nature of RIF mass by high-resolution ultrasound and multidetector CT scan, the patients presenting with clinically palpable mass in RIF need not to undergo time consuming, uncomfortable and unpalatable barium study. The objective is to evaluate the diagnostic precision of CT and ultrasonography in the diagnosis of right iliac fossa masses and to assess the effectiveness of USG in diagnosing various right iliac fossa masses in comparison with CT scan in terms of sensitivity, specificity, and predictive accuracy. Methods: The study was conducted on 35 patients presenting with right iliac fossa mass who were stable enough to undergo USG followed by CT scan. The time gap between these studies had kept to minimum to make the studies comparable. USG and CT scan was performed by 2 expert radiologists, who had been blinded of each other findings. Results: More than 50% cases were related to appendicular pathology. Ultrasound abdomen had a sensitivity and specificity of 88.9% and 94.11% in diagnosis of appendicular mass, 71.42% and 96.42% in diagnosis of appendicular abscess, 66.7% and 96.6% in diagnosis of ileo-caecal tuberculosis, 50% and 100% in diagnosis of carcinoma caecum respectively as compared to CT scan. Conclusions: USG is the most easily available bed side investigation and excellent screening test for RIF mass. However, CECT whole abdomen remains the gold standard investigation for etiological diagnosis of RIF mass.

May-Thurner syndrome: a review

May-Thurner syndrome (MTS) is an underdiagnosed entity and level of suspicious should be raised during evaluation of deep vein thrombosis (DVT) of the left lower limb, especially in women between the third and fifth decades of life. To correctly identify MTS, high clinical suspicion, and imaging studies such as phlebography, magnetic resonance imaging (MRI), computed tomography (CT), and intravascular ultrasound are required. In correct clinical context, CT/MRI venography can be used to facilitate early diagnosis and treatment that includes pharmaco-mechanical thrombolysis with angioplasty and stenting, both of which minimize late morbidity from post-thrombotic syndrome.

Failed limb salvage by microsurgery, resolved by super-microsurgery

Advances in perforating artery flaps have improved reconstruction in various body parts, particularly the lower extremities, offering benefits in patient quality of life and reduced public health service costs. The use of flaps and microsurgery extends beyond trauma to address conditions like osteomyelitis, tumor resection, osteoarthritis, and post-radiation necrosis. Notably, the superficial circumflex iliac artery perforator flap (SCIP) is highlighted for its thin profile and utility in limb coverage, minimizing donor site morbidity. Microsurgical techniques contribute to limb salvage, reducing amputation risks in severe fractures and post-osteosynthesis complications. A 29-year-old male with cerebral palsy suffered bimalleolar fracture from a high-energy motor vehicle accident. Initial ALT flap reconstruction failed, leading to flap removal and osteosynthesis exposure. After 48 hours, removal of the flap was necessary due to venous thrombosis. Salvage with SCIP flap involved anastomosis to perforators of both posterior tibial artery and vein. This case details a patient with a bimalleolar fracture post-motorcycle accident, initially treated with conventional microsurgery using an ALT flap. Complications arose from venous thrombosis, necessitating flap removal. Salvage was achieved through a SCIP flap with supermicrosurgery techniques, employing 0.5 mm anastomosis for improved functionality and reduced complications in flap recovery and donor site comorbidities. Successful outcomes in microsurgery and supermicrosurgery necessitate comprehensive training. Specialized limb salvage centers must possess specific equipment and instruments for these techniques. The literature reviewed doesn't indicate contraindications related to the patient's mental state for the execution of microsurgery and supermicrosurgery.

Role of height of an individual and low lying pubic tubercle as risk factors of inguinal hernia: case controlled study

Background: Hernia is defined as abnormal protrusion of whole or a part of a viscus through the wall that contains it. Among all external abdominal hernias, inguinal hernia is one most typically encountered. Many factors are responsible for the formation of hernia. We intended to study the risk of inguinal hernia in low lying pubic tubercle. Methods: The study was conducted on patients in AJIMS, India. It is a case-control study with 80 cases and 80 control meeting inclusion criteria, in all patients, following parameters SS line, ST line, height, weight was recorded and evaluated. Results: The average SS value for case which was much above the average in control.ST value was higher case group than control group, and p<0.0001 which was significant. when it comes to the mean of (SS/ST ratio)/height was higher in the case group than control group. Results developed show majority of the subjects with a low-lying pubic tubercle were inguinal hernia patients. Conclusions: Based on my study, interspinal distance (SS line) and pubo-spinal distance (ST line) are more in cases compared to control. Configuration of bony pelvis seems to be a major contributing factor in determining the risk of development of inguinal hernia as evidenced by the variations in ST length. This low-lying pubic tubercle is very important before selecting the patient for any surgical correction. So, the proper demonstration of anatomy of inguinal region is very important before selecting the surgical technique.

Application of iliac vein molding and stent implantation through the ipsilateral great saphenous vein approach in daytime treatment mode / 北京大学学报(医学版)

Objective:To explore the feasibility and recent efficacy of iliac vein molding and stenting in daytime treatment mode in patients with iliac vein stenosis.Methods:Medical records of iliac vein molding and stenting performed in the ipsilateral great saphenous vein approach conducted from February 2017 to March 2022 were retrospective reviewed.There were 21 cases,6 males and 15 females.Age ranged from 37 to 79 years[(62.5±10.2)years].The stenosis in the 21 limbs simply involved the common iliac veins in 16 patients,2 patients had the simple and external iliac veins,and both the total and external iliac veins in 3 patients.Both iliac vein molding and iliac vein stenting were performed through the ipsilateral great saphenous vein approach.The patients with simple iliac vein stenosis with great saphenous vein valve insufficiency also underwent radiofrequency closure of great saphenous vein and flexural vein sclerosis therapy simultaneously.Regular postoperative direct oral anticoagulants therapy and stress therapy were followed.All the patients were hospitalized for less than 24 h.Results:All the 21 patients operations were successful(the success rate was 100％),without any intraoperative compli-cations.Immediate postoperative complications were puncture point bleeding in 1 case.The bandage gauze was completely wet.The bleeding was stopped after 5min of recompression.All the patients were hospitalized for less than 24 h.Follow-up results:The 3-month follow-up rate after operation was 100％.Absolute effective 18 cases(18/21,85.7％).Relatively effective(postmentation still after surgery,but with less extent)in 3 cases(3/21,14.3％).The iliac vein stents were unobstructed,and the trunk of the great saphenous vein was well closed in the patients with great saphenous vein radiofrequency treat-ment.The 6-month follow-up rate after operation was 71.4％(15/21).Of these,14 cases(14/15,93.3％)were absolutely effective.Relatively effective(postmentation still after surgery,but with less ex-tent)in 1 case(1/15,6.7％).The iliac vein stents were no restenosis or obstruction,and the trunk of the great saphenous vein was well closed in the patients with great saphenous vein radiofrequency treat-ment.Conclusion:The interventional treatment technique of iliac vein stenosis is feasible in the daytime treatment mode,with clear advantages and satisfactory recent efficacy.

The clinical efficacy and safety of bilateral internal iliac artery Fogarty balloon occlusion in uterine curettage for patients with cesarean scar pregnancy / 介入放射学杂志

Objective To discuss the clinical efficacy and safety of bilateral internal iliac artery Fogarty balloon occlusion in uterine curettage for patients with cesarean scar pregnancy(CSP).Methods The clinical data of a total of 80 CSP patients,who were admitted to the Fuyang People's Hospital of China between January 2021 and September 2022 to receive treatment,were retrospectively analyzed.The patients were divided into the observation group(n=40)and the control group(n=40).For the patients of the observation group,the hysteroscopic uterine curettage was carried out under the situation of bilateral internal iliac artery Fogarty balloon occlusion and during the operation the internal iliac artery was intermittently blocked.The embryo was removed,and the hemostasis was accomplished by electrocoagulation or surgical suture.For the patients of the control group,the hysteroscopic uterine curettage was performed within 1-2 days after uterine artery embolization(UAE).The digital subtraction angiography(DSA)fluoroscopy time,body surface radiation dose,blood loss during uterine curettage,time spent for uterine curettage,length of hospital stay,and postoperative follow-up results were compared between the two groups.Results Successful uterine curettage was accomplished and the uterus was retained in all the patients.In the observation group,no balloon-related complications occurred.In the control group,all the 40 patients developed different degrees of fever,pain at uterine area,and other post-embolization symptoms after UAE.In the observation group and the control group,the DSA fluoroscopy time was(9.2±1.1)seconds and(1 273.6±141.1)seconds respectively,the body surface radiation dose was(7.7±0.8)mGy and(1 503.8±101.8)mGy respectively,the differences between the two groups were statistically significant(both P＜0.05);the blood loss during uterine curettage was(30.3±14.7)mL and(27.5±13.2)mL respectively,the time spent for uterine curettage was(41.6±16.2)min and(42.8±15.0)min respectively,the differences between the two groups were not statistically significant(both P＞0.05);the length of hospital stay was(6.0±0.7)days and(7.3±0.8)days respectively,the difference between the two groups was statistically significant(P＜0.05).All patients were followed up for more than 3 months,the time of β-hCG turning to negative,time of vaginal bleeding,time of menstruation returning to normal,and patient satisfaction rate in the observation group were(21.1±2.4)days,(8.2±1.1)days,(29.5±2.2)days and 95.0%(38/40)respectively,which in the control group were(24.6±3.3)days,(13.6±2.6)days,(46.7±7.3)days and 67.5%(27/40)respectively,the differences in the above indexes between the two groups were statistically significant(all P＜0.05).Conclusion In performing uterine curettage for CSP patients,both bilateral internal iliac artery Fogarty balloon occlusion and UAE can significantly reduce the intraoperative blood loss,but bilateral internal iliac artery Fogarty balloon occlusion is superior to UAE in reducing radiation dose,in shortening the patient's hospital stay,the time of β-hCG turning to negative,the time of vaginal bleeding and the time of menstruation returning to normal,and in improving the patient satisfaction rate.

The efficacy of hip arthroscopy for concurrent femoroacetabular and subspine impingement / 中华骨科杂志

Objective:To assess the clinical outcomes of hip arthroscopy in patients with concurrent femoroacetabular impingement (FAI) and subspine impingement (SSI).Methods:Data were retrospectively reviewed for patients with both FAI and SSI who underwent hip arthroscopy surgery from August 2021 to May 2022. A total of 23 patients (23 hips) followed up for more than 1 year, including 10 males and 13 females, 9 left hips and 14 right hips, with an average age of 31.3±4.6 years (range, 25-45 years). Subspine decompression by anterior inferior spine (AIIS) shaping for SSI was performed during hip arthroscopy in addition to labral repair and bony correction for FAI in the patients with concurrent FAI and SSI. Clinical outcomes were evaluated using preoperative and 1-year postoperative measures: lateral center-edge (LCE) angle, α angle on 45° Dunn view X-rays, maximum hip flexion angle, hip flexion and knee extension strength, visual analogue scale (VAS) for pain, modified Harris Hip Scores (mHHS), and International Hip Outcome Tool-12 (iHOT-12).Results:Of the 23 patients, 20 had type 2 AIIS and 3 had type 3 AIIS. At 1-year follow-up after surgery, there were significant improvements: LCE angle decreased (33.3°±6.1° to 31.7°±4.1°, t=1.076, P=0.288), α angle reduced (63.7°±8.5° to 50.0°±6.6°, t=6.116, P<0.001), hip flexion angle increased (107.4°±6.0° to 120.2°±4.4°, t=8.269, P<0.001), VAS scores decreased (4.0±1.1 to 1.0±1.1, t=9.591, P<0.001), mHHS improved (62.6±4.9 to 87.5±8.1, t=12.700, P<0.001), and iHOT-12 scores rose (51.4±4.9 to 75.7±7.7, t=12.593, P<0.001). There was no significant difference in the strength of hip flexion and knee extension between preoperative and follow-up ( t=0.930, P=0.357 and t=0.050, P=0.960, respectively). There were no reports of traction-related complications (such as skin necrosis and nerve paralysis), severe adverse events (such as femoral neck fractures, deep vein thrombosis in the lower limbs, intra-articular infections, ectopic ossification and hip instability), or the need for revision surgery. Conclusion:Subspine decompression by anterior inferior spine (AIIS) shaping for SSI during conventional hip arthroscopy is safe and effective, enhancing hip function and alleviating pain at 1-year follow-up without significant complications.

Objective:To investigate the feasibility and clinical value of endovascular treatment of iliac vein disease via the great saphenous vein approach.Methods:Eighty-six patients with nonthrombotic left iliac vein compression lesions identified by anterograde lower limb vein angiography were divided into 2 groups: group A ( n=46) was treated via great saphenous vein and group B ( n=40) was treated via femoral vein. The success rate of puncture, time consuming of puncture catheterization, postoperative bed immobilization and complication rate of puncture were observed and compared between the two groups. Results:The puncture success rate was 97.8% (45/46) in group A and 100% (40/40) in group B, there was no significant difference between the two groups（ P>0.05）. The average puncture time was (9.4±2.7) min in group A and (5.5±1.3) min in group B ( P<0.05). The complication rate of group A was lower than that in group B ( P<0.05). The patency rate of iliac vein stent was 100%, as indicated by venous color ultrasound or angiography. Conclusion:Endovascular treatment of iliac vein disease via great saphenous vein approach is a safe and feasible method with less trauma and easier postoperative care.

Type A Acute Aortic Dissection Complicated with Rupture of the External Iliac Artery / 日本心臓血管外科学会雑誌

A 67-year-old man suffered sudden chest pain. Computed tomography with contrast medium revealed dissection from the ascending aorta to the bilateral iliac arteries and hematoma around the left external iliac artery. Type A acute aortic dissection complicated with rupture of the left external iliac artery was diagnosed. Urgent endovascular repair (stent-graft implantation) was first performed for the arterial rupture more critical than the aortic dissection. On the next day after satisfactory hemostasis and hemodynamical stabilization, semi-urgent ascending aortic replacement was achieved, and the patient survived. Acute aortic dissection complicated with rupture of the aortic branch was extremely rare, and only 5 cases have been reported in the English literature.

@#Objective To analyze and compare the treatment of HeppleⅤ talus osteochondral injury(OLT)with autologous periosteal iliac bone graft and allogeneic bone powder combined with platelet rich gel(PRP).Methods Totally 62 HeppleⅤOLT patients admitted to our hospital from October 2018 to October 2022 were selected as the research subjects.They were divided into a transplantation group(31 patients received autologous periosteal iliac bone transplantation treatment)and a combination group(31 patients received allogeneic bone powder combined with PRP treatment)based on their treatment methods.Conduct a 12 month postoperative outpatient follow-up study on patients,evaluate and compare the treatment effectiveness,ankle joint range of motion(ROM),American Society of Orthopedic Foot and Ankle Surgeons(AOFAS)ankle posterior foot score,pain score,satisfaction,and incidence of complications between the two groups of patients at 12 months after surgery.Results The total effective rate of the transplantation group(96.77%)was not significantly different from that of the combination group(93.55%,P>0.05).At 12 months after surgery,the ROM and AOFAS scores of both groups improved(P<0.05),and there was no statistically significant difference between the groups(P>0.05).At 1 month,3 months,6 months,and 12 months after surgery,the pain scores of both groups decreased compared to before surgery(P<0.05).The subjective overall satisfaction of patients in the transplantation group(77.42%)was lower than that in the combination group(96.77%,P<0.05).The total incidence of complications in the transplantation group(19.35%)was significantly higher than that in the combination group(3.23%,P<0.05).Conclusion Allogeneic bone powder combined with PRP can avoid additional surgical incisions,increase patient subjective satisfaction,and increase the incidence of postoperative complications.

La morbilidad del sitio donante de injerto de cresta ilíaca posterior podría ser un hecho sobreestimado. Estudio en pacientes con fusión lumbar posterolateral abierta / The morbidity of the posterior iliac crest bone graft harvesting could be an overestimated fact. Study in patients with open posterolateral lumbar fusion

Resumen: Introducción: la fusión espinal es utilizada para tratar, entre otras patologías, las enfermedades degenerativas discales. El injerto óseo autólogo de cresta ilíaca es el estándar de oro para aumentar las probabilidades de fusión; sin embargo, no está exento de complicaciones. Objetivos: investigar si los pacientes a los que se les recolecta injerto de cresta ilíaca posterior y son cegados al lado del sitio donante, pueden identificar de qué lado se tomó dicho injerto y si la intensidad de este dolor está en relación con la cantidad de injerto obtenido. Material y métodos: trabajo prospectivo, experimental, aleatorizado y comparativo, simple ciego. Se incluyeron pacientes adultos operados entre Julio de 2019 hasta Abril de 2020, a los cuales se les realizó una cirugía primaria de artrodesis lumbar posterolateral abierta instrumentada, con colocación de injerto óseo autólogo de cresta ilíaca. Se dividió a los pacientes en dos grupos aleatorizados. La cantidad de injerto a recolectar fue de acuerdo a las necesidades quirúrgicas. Se interrogó por el dolor según escala visual analógica al primer, tercer y sexto mes de la cirugía, siempre solicitando que se identifique el lado más doloroso. Resultados: se analizaron 44 pacientes (n = 23 cresta derecha, n = 21 cresta izquierda). La mayoría de los pacientes no lograron identificar el lado del cual se obtuvo el injerto óseo, con una diferencia estadística ampliamente significativa (p = 0.0001). Conclusión: la obtención de injerto óseo de cresta ilíaca es un procedimiento efectivo y seguro, que mejora las probabilidades de fusión sin aumentar la morbilidad del paciente.

Abstract: Introduction: spinal fusion is used to treat, among other pathologies, the degenerative intervertebral disc disease. Autologous iliac crest bone grafting is the golden standard treatment for increasing the rate of fusion; however, it isn't free of complications. Objectives: to investigate whether patients who have posterior iliac crest graft harvesting and are blinded to the donor site, can identify from which side the graft was harvested, and whether the intensity of this pain is related to the amount of graft obtained. Material and methods: prospective, experimental, randomized and comparative, single-blind study. Adult patients who underwent primary instrumented open posterolateral lumbar fusion with autologous iliac crest bone graft between July 2019 and April 2020 were included. Patients were divided into two randomized groups. The amount of graft to be harvested was according to surgical needs. The patients were asked about pain according to the visual analogue scale in the first, third and sixth months after surgery, always requesting that the most painful side be identified. Results: a total of 44 patients (n = 23 right crest, n = 21 left crest) were analyzed. Most patients were unable to identify the side from which the bone graft was harvested, with a statistically significant difference (p-value 0.0001). Conclusion: iliac crest bone graft harvesting is an effective and safe procedure that improves the rates of fusion without increasing the patient's morbidity.

Aneurisma micótico de ilíaca derecha / Right iliac mycotic aneurysm

Salmonella es una de las principales causas de gastroenteritis y bacteriemia a nivel mundial. En determinadas ocasiones, puede ser, además, el agente causal de aneurisma de la arteria ilíaca en pacientes con factores predisponentes: mayores de 60 años, diabéticos, hipertensos y sometidos a intervenciones quirúrgicas. El objetivo de la publicación fue evidenciar la presencia de aneurisma micótico por salmonella en iliaca derecha, en un paciente masculino que presentó fiebre, deposiciones líquidas y masa tumoral en región inguinal; para el cual, el diagnóstico clínico, de laboratorio, la ultrasonografía vascular y el Angiotac, ayudaron a tomar la conducta terapéutica más adecuada. Los aneurismas de iliacas de causa bacteriana no son tan infrecuentes, y el cirujano vascular debe saber qué conducta terapéutica elegir en cada caso. Los procederes endovasculares y la cirugía a cielo abierto son dos opciones que deben ser combinadas siempre con la terapia antimicrobiana(AU)

Salmonella is one of the main causes of gastroenteritis and bacteremia worldwide. On certain occasions, it can also be the causative agent of iliac artery aneurysm in patients with predisposing factors: older than 60 years, diabetics, hypertensive and undergoing surgery. The objective of the publication was to show the presence of mycotic aneurysm due to salmonella in the right iliac artery, in a male patient who presented fever, liquid stools and tumor mass in the inguinal region. Clinical and laboratory diagnosis, vascular ultrasonography and Angiotac, helped to take the most appropriate therapeutic approach. Bacterial iliac aneurysms are not so uncommon, and the vascular surgeon must know which therapeutic approach to choose in each case. Endovascular procedures and open surgery are two options that should always be combined with antimicrobial therapy(AU)

Aneurisma de arteria iliaca: una causa de dolor abdominal agudo de alto riesgo

El dolor abdominal de alto riesgo es una condición común en los servicios de emergencia y está asociado a una alta morbilidad y mortalidad, si no se diagnostica y trata de manera rápida y precisa. Un hombre con síntomas de cólico nefrítico se presentó en emergencia con dolor abdominal intenso y deterioro clínico. Después de una tomografía, se encontró una imagen aneurismática en la arteria iliaca común primitiva izquierda. El paciente fue trasladado a sala de operaciones para una reparación quirúrgica, pero falleció. El dolor abdominal de alto riesgo requiere un abordaje diagnóstico integral y tratamiento individualizado para prevenir complicaciones graves. El aneurisma de la arteria iliaca complicado es una causa potencialmente grave de dolor abdominal en hombres fumadores de edad avanzada con antecedentes de hipertensión y aterosclerosis.

Life-Threatening abdominal pain is a common condition in emergency departments and it is associated with high morbidity and mortality, if not promptly and accurately diagnosed and treated. A man with symptoms of renal colic presented to the emergency room with severe abdominal pain and clinical deterioration. After a CT scan, an aneurysmatic image was found in the left primitive iliac artery. The patient was taken to an operating room for surgical repair but died. Life-Threatening abdominal pain requires a comprehensive diagnostic approach and individualized treatment to prevent serious complications. The complicated iliac artery aneurysm is a potentially serious cause of abdominal pain in elderly male smokers with a history of hypertension and atherosclerosis.

Tromboembolismo pulmonar asociado a COVID-19 en paciente con síndrome de May-Thurner / COVID-19-associated Pulmonary Thromboembolism in a Patient with May-Thurner Syndrome

Introducción: El síndrome de May-Thurner es una enfermedad cuya prevalencia real es desconocida. Suele ser asintomática y las manifestaciones clínicas aparecen en el contexto de las complicaciones asociadas a la enfermedad. La aproximación diagnóstica se realiza por medio de imágenes, donde se identifican alteraciones patognomónicas que permiten descartar diagnósticos diferenciales. Se ha demostrado que la COVID-19 genera un estado protrombótico, que en contexto del síndrome de May-Thurner puede derivar en complicaciones tromboembólicas. Objetivo: Comparar la clínica y la posible relación de la enfermedad tromboembólica venosa en el curso de la COVID-19 en pacientes con SMT. Caso clínico: Mujer de 24 años, secretaria de profesión y residente en Bucaramanga. Presentó un cuadro clínico de 20 días de evolución que inició con rinorrea hialina, tos ocasional y mialgias; cinco días después manifestó fiebre no cuantificada y tos con expectoración hemoptoica. Conclusiones: Dentro de la fisiopatología de la infección por SARS-CoV-2 se desarrollan mecanismos procoagulantes, lo cual incrementa el riesgo de eventos trombóticos en pacientes con o sin factores de riesgo(AU)

Introduction: May-Thurner syndrome is a disease whose actual prevalence is unknown. It is usually asymptomatic and clinical manifestations appear in the context of complications associated with the disease. The diagnostic approach is performed by imaging, where pathognomonic alterations are identified to rule out differential diagnoses. It has been demonstrated that COVID-19 generates a prothrombotic state, which particularly in patients with May-Thurner syndrome would lead to thromboembolic complications. Objective: To compare the clinical and possible relationship of venous thromboembolic disease in the course of COVID-19 in patients with May-Thurner syndrome. Clinical case: 24-year-old woman, secretary by profession and resident in Bucaramanga, Colombia. She presented a clinical picture of 20 days of evolution that began with hyaline rhinorrhea, occasional cough and myalgias; five days later she manifested unquantified fever and cough with hemoptotic expectoration. Conclusions: Within the pathophysiology of SARS-CoV-2 infection, procoagulant mechanisms develop, which increases the risk of thrombotic events in patients with or without risk factors(AU)

Rotura espontánea de vena ilíaca: una causa infrecuente de abdomen agudo hemorrágico / Spontaneous rupture of the iliac vein: a rare cause of intra-abdominal hemorrhage

RESUMEN La rotura espontánea de la vena ilíaca es una causa poco frecuente de hemorragia retroperitoneal exanguinante. Generalmente está asociada con un traumatismo y las lesiones iatrogénicas durante la cirugía de hemiabdomen inferior o pelviana. Ocurre con frecuencia del lado izquierdo y afecta indistintamente a la vena ilíaca común como a la externa. Con el objetivo de destacar las características clínicas e imagenológicas de esta infrecuente entidad, presentamos un caso fatal de rotura espontánea de la vena ilíaca externa izquierda. El tratamiento se basa en la reparación quirúrgica abierta o, en casos seleccionados, en la colocación de prótesis por vía endovascular. Es necesario un alto índice de sospecha, ya que el diagnóstico y el tratamiento tempranos son fundamentales para mejorar las altas tasas de morbimortalidad que conlleva esta entidad.

ABSTRACT Spontaneous rupture of the iliac vein is a rare cause of fatal retroperitoneal hemorrhage that is generally associated with trauma and iatrogenic injury during lower abdominal or pelvic surgery. It usually occurs in the left common and external iliac veins. We report a fatal case of spontaneous rupture of the left external iliac vein to emphasize the clinical and imaging characteristics of this rare condition. Treatment is based on open surgical repair or endovascular stenting in selected cases. High level of suspicion is essential for early diagnosis and treatment to improve the associated morbidity and mortality.

Nefroprotección en frío para reparo de ectasia aórtica y aneurismas ilíacos bilaterales ante la presencia de riñón ectópico pélvico / Cold nephroprotection for repair of aortic ectasia and bilateral iliac aneurysms in the presence of pelvic ectopic kidney

Resumen Los riñones ectópicos pélvicos solitarios asociados a degeneración aneurismática de las arterias ilíacas y la aorta abdominal son eventos muy raros. Los enfoques quirúrgicos para la corrección de aneurismas con compromiso renal son un desafío por la falta de consenso actual, en especial cuando cursan con riñones ectópicos pélvicos solitarios funcionales asociados. Por tal motivo, una de las estrategias que ha demostrado buenos resultados a corto y mediano plazo es la nefroprotección en frío, la cual puede ser usada con seguridad en estos pacientes. En el caso que se presenta, se evidenció una ectasia aórtica con aneurismas ilíacos bilaterales asociados con un riñón ectópico pélvico solitario en un paciente masculino de 75 años, con hipertensión arterial y dislipidemia. Se realizó una reconstrucción aortoilíaca bilateral y una reconstrucción de la arteria hipogástrica, además de reimplante de la arteria renal ectópica bajo irrigación renal en frío, sin complicaciones y preservación de la función renal.

Abstract Solitary pelvic ectopic kidneys associated with aneurysmal degeneration of the iliac arteries and abdominal aorta are very rare events. Surgical approaches for the correction of aneurysms with renal involvement are challenging due to the lack of current consensus, especially when they are associated with functional solitary pelvic ectopic kidneys. For this reason, one of the strategies that has shown good results in the short and medium term is cold nephroprotection, which can be used safely in these patients. In the present case, aortic ectasia with bilateral iliac aneurysms associated with a solitary pelvic ectopic kidneys was evidenced in a 75-year-old male patient with arterial hypertension and dyslipidemia. Bilateral aortoiliac reconstruction was performed with hypogastric artery reconstruction and reimplantation of the ectopic renal artery under cold renal irrigation, without complications and preservation of renal function.

Simultaneous innervated and vascularized iliac bone flap for reconstructing mandible and nerve defects / 口腔疾病防治

@#The functional reconstruction of large maxillofacial defects is a major issue in oral and maxillofacial surgery, and autologous bone transplantation is the main method. However, bone is readily absorbed following an autologous bone transplant. Even with vascular anastomosis, spontaneous osteoporosis of transplanted bone is still serious, which affects dental implantation and functional recovery. Therefore, osteoporosis of the grafted bone has become one of the main complications of jaw reconstruction, and there is no preventive measure. The problem that autologous bone with sufficient blood supply cannot avoid osteoporosis suggests that systemic factors such as nerves, which have been neglected in traditional methods, may regulate the internal environment of the transplanted bone. Based on previous studies on the regulation of mesenchymal stem cells by the neural microenvironment, we initiated a new surgical procedure for innervated and vascularized iliac bone flaps based on animal model and cadaver studies. In the innervated and vascularized iliac bone flap, vascular microanastomosis was performed in conjunction with microneuronal anastomosis between the simultaneously harvested ilioinguinal nerve (which innervates the iliac bone and is usually sacrificed and neglected in the conventional vascularized iliac bone flap) and the inferior alveolar nerve proximally and with the mental nerve distally. By conducting clinical retrospective studies and prospective randomized controlled trials, we proved that the novel method of simultaneous innervated iliac bone transplantation can not only prevent bone resorption but also restore the sensation of adjacent soft tissues such as the lip. This may solve the key problems of sensory loss and osteoporosis after mandibular reconstruction, ensure the success of dental implant dentures, and put forward the new concept of "blood supply + innervation" bi-system bone transplantation.
