ABSTRACT

La técnica de la endarterectomía carotídea por eversión no es novedosa como pudiera parecer, pero es cierto que quedó en desuso, a pesar de los excelentes resultados, principalmente debido a la dificultad de inserción del shunt que en las décadas setenta y ochenta del siglo pasado se empleaba de forma rutinaria. Los autores de este artículo describen la modalidad que ellos realizan, una endarterectomía carotídea por eversión modificada, sin seccionar la arteria carótida en ningún momento, y que fue ya descrita por Cooley y modificada por Anderson. Ellos señalan cuidadosamente los pasos e indican los trucos para que el procedimiento sea satisfactorio. En la mayoría de los casos la realizan con anestesia local y hacen una arteriografía de control intraoperatoria.(AU)


The technique of carotid endarterectomy by eversion is not new as it might seem, but it is true that it stopped being used, despite the excellent results, mainly because the difficulty of inserting the shunt that in the seventies and eighties of the last century was routinely used. The authors describe in this paper the modality that they perform, a modified eversion carotid endarterectomy without sectioning the carotid artery at any time, and that was already described by Cooley and modified by Anderson. They carefully point out the steps and describe the tricks to make the procedure successful. In most cases, they do it under local anesthesia and systematically carry out an intraoperative control angiography.(AU)

ABSTRACT

BACKGROUND: Endovascular techniques have become an essential tool for treatment of thoracic aortic pathology. The objective of this study was to analyze indications and results of thoracic endovascular aortic repair (TEVAR) in vascular surgery units, through a retrospective and multicentric national registry called Regis-TEVAR. METHODS: From 2012 to 2016, a total of 287 patients from 11 vascular surgery units, treated urgently and electively, were recruited consecutively. The primary variables analyzed are mortality, survival, and reintervention rate. The following indications for TEVAR were also analyzed: aortic dissections, thoracic aneurysms, traumatisms, and intramural hematomas or penetrating ulcers, as well as results and postoperative complications in accordance with each indication. RESULTS: Of the 287 TEVAR performed (239 men, mean age 64.1 ± 14.1 years), 155 were because of aortic aneurysm (54%), 90 because of type B aortic dissection (31.4%), 36 because of traumatic aortic rupture (12.5%), and 6 because of penetrating ulcers or intramural hematomas (2.1%). Overall mortality at 30 days was 11.5% (18.5% in urgent and 5.3% in elective), being higher in dissections (13.3%). The median actuarial survival was 73% at 4 years. The stroke rate was 3.1%, and the rate of spinal cord ischemia was 4.9%. Aortic reoperations were necessary in 23 patients (8.1%). CONCLUSIONS: This registry provides complete and reliable information on real clinical practice of TEVAR in Spain, with results similar to international series of open surgery. In accordance with these data, TEVAR can be performed with acceptable morbidity and mortality and with low rates of postoperative complications.

ABSTRACT

A 79-year old patient with an asymptomatic 63-mm infrarenal abdominal aortic aneurysm, confirmed on computed tomography, was admitted in our unit. The patient had undergone kidney transplantation years before, due to renal failure secondary to polycystic kidney disease. Renal function at admission was normal. The aneurysm had a very short neck, and a standard endovascular aortic repair procedure was not feasible. Therefore, the 2 renal arteries were embolized with coils and endovascular repair of the aneurysm, covering the ostia of the renal arteries, was achieved placing the endoprosthesis up to the level of the superior mesenteric artery. The course of the patient was uneventful and was discharged without complications. Endovascular repair in patients without infrarenal aortic necks and nonfunctional kidneys secondary to polycystic kidney disease can be achieved with safety embolizing and covering the ostia of the renal arteries.

ABSTRACT

BACKGROUND: Ureteroarterial fistulas (UAFs) have a low incidence but are a potentially fatal cause of hematuria. Initially treated by open surgery, endovascular techniques have decreased potential complications. MATERIAL AND METHODS: We present a short series of UAFs (n = 5) treated in our institution in the last 10 years: 1 case showed up after aorta-iliac bypass surgery, 1 case after endovascular aortic repair and embolization of right hypogastric artery, and 3 cases after oncological surgeries. We review the published literature via PubMed. RESULTS: The different approaches (2 open and 3 endovascular procedures) were based on the clinical situation of the patients and on technical limitations. Three patients died after the procedure (2 after open surgery and 1 after endovascular treatment). In our institution, endovascular treatment showed good results in terms of early complications and associated mortality compared with open surgery. CONCLUSIONS: UAF is a rare but a potentially fatal complication in patients with predisposing factors. No long-term follow-up has been published to assess the possible complications arising from the technique, such as prosthetic infection. No antibiotic treatment protocols have been established, so long-term follow-up is necessary to determine late complications.

ABSTRACT

Critical limb ischemia is the end stage of peripheral arterial occlusive disease, with a deep impact in patient's quality of life. In some patients, there is no revascularizing treatment options, that determines major limb amputation in a high percentage of patients, not only for uncontrolled limb pain but also for complications of the trophic lesions. In the last years, several studies have shown the possibility to increase the perfusion in the ischemic tissue, by recombinant proteins, gene therapy or cellular therapy, all of them known as therapeutic angiogenesis. Several good results have been published but the way of treatment, doses and possible adverse effects still lack definitive conclusions. Randomized comparative studies should be carried out to determine the best treatment option.

ABSTRACT

La isquemia crítica es el estadio terminal de la enfermedad arterialperiférica, con gran impacto en la calidad de vida del paciente. En algunoscasos no hay posibilidad de tratamiento revascularizador, loque determina la amputación de la extremidad en un porcentaje elevadode los pacientes, bien por dolor incontrolado, bien por complicaciónde las lesiones tróficas. Diversos estudios han demostrado la posibilidadde mejorar la perfusión tisular mediante el uso de factoresde crecimiento (proteínas recombinantes), genoterapia o tratamientocelular, en lo que se ha denominado angiogenia terapéutica. Sin embargo,la forma de tratamiento, la dosis, la vía de administración y losposibles efectos adversos están todavía en fase de estudio.Aunque los resultados de los trabajos afirman la mejoría de la perfusióntisular, serán necesarios estudios aleatorizados y comparativosque demuestren cuál de los tratamientos ofrece un mejor intervalo deseguridad terapéutica en los casos no revascularizables

ABSTRACT

Introducción. Los aneurismas de las arterias viscerales son entidades poco comunes con una incidencia estimada de 0,01-2%. Su importancia clínica se debe a que su historia natural se caracteriza por una tendencia a la rotura, con una tasa de mortalidad que puede llegar a ser de hasta un 70%. Con el desarrollo de las nuevas técnicas de imagen ha crecido el número de hallazgos casuales de esta patología. El tratamiento clásico de estos aneurismas ha consistido en la cirugía ‘a cielo abierto’, pero con el desarrollo de las técnicas endovasculares, se ha establecido una alternativa terapéutica con menores tasas de morbimortalidad. Casos clínicos. Presentamos un caso de aneurisma de arteria mesentérica superior, tratado mediante cirugía abierta, y otro caso de aneurisma de arteria hepática tratado mediante terapia endovascular, ambos sintomáticos y con buena evolución postoperatoria. Conclusiones. El tratamiento de los aneurismas de arterias viscerales tiene como finalidad evitar su rotura y las complicaciones derivadas. El riesgo de rotura viene determinado principalmente por su tamaño y localización. La terapia endovascular presenta como principal ventaja la menor invasividad del procedimiento; sin embargo, no existen estudios comparativos, por lo que no podemos hablar de la superioridad de una terapia respecto de la otra en el tratamiento de los aneurismas viscerales


Introduction. Aneurysms in the visceral arteries are uncommon conditions with an estimated incidence of 0.01-2%. Their clinical importance derives from the fact that their natural history is characterised by a tendency to rupture, with a mortality rate that can reach up to 70%. With the development of the latest imaging techniques the number of chance findings of this pathology has grown. Treatment of these aneurysms has traditionally consisted in open surgery, but the advances in endovascular techniques have made it possible to establish a therapeutic alternative with lower morbidity and mortality rates. Case reports. We report one case of superior mesenteric artery aneurysm, which was treated using open surgery, and another case of hepatic artery aneurysm that was treated by means of endovascular therapy; both of them were asymptomatic and post-operative progress was good in the two cases. Conclusions. The aim of treating aneurysms in visceral arteries is to prevent rupture and the ensuing complications. The risk of rupture is chiefly determined by their size and location. The main advantage of endovascular therapy is that the procedure is less invasive. Nevertheless, to date no comparative studies have been conducted and so we cannot talk of one therapy being better than the other in the treatment of visceral aneurysms

ABSTRACT

Introducción. La isquemia aguda por embolización distal de un aneurisma cubital es infrecuente. La mayoría de los casos descritos en la bibliografía se relacionan con el síndrome del martillo hipotenar (SMH). Caso clínico. Varón de 45 años, con dolor, parestesias y frialdad de inicio súbito en el cuarto y el quinto dedos del miembro superior derecho. En la exploración física había pulsos presentes y simétricos en miembros superiores. Frialdad y subcianosis en el quinto dedo derecho y en menor grado en el cuarto, leve disminución de la sensibilidad y movilidad conservada. Sensación de masa no pulsátil en la región hipotenar derecha. El eco-Doppler mostró una curva de oclusión distal cubital y un aneurisma trombosado de arteria cubital de 0,4 × 0,8 cm en la región hipotenar. La fotopletismografía era plana en el cuarto y quinto dedos. La angiorresonancia mostraba un aneurisma de arteria cubital distal con ausencia del arco palmar profundo y la arteriografía una arteria cubital de fino calibre con retraso en su opacificación. Conclusiones. Por los hallazgos clinicorradiológicos, y al referir el paciente el traumatismo repetitivo en la eminencia hipotenar por el uso del ordenador personal, se estableció el diagnóstico de SMH atípico. La evolución clínica fue favorable con tratamiento médico (heparina de bajo peso molecular y analgesia), desapareciendo la sintomatología durante las primeras 24 horas


Introduction. Acute ischaemia due to distal embolisation of an ulnar aneurysm is infrequent. Most of the cases reported in the literature are related to hypothenar hammer syndrome (HHS). Case report. We report the case of a 45-year-old male who suffered the sudden onset of pain, paresthesias and coldness in the 4th and 5th fingers of the right hand. The physical examination showed that pulses were present and symmetrical in the upper limbs. There was also coldness and pallor in the fifth finger of the right hand and to a lesser extent in the fourth, slightly reduced sensitivity and preserved mobility. A non-pulsating mass could be felt in the right hypothenar region. Doppler ultrasound scan revealed a distal ulnar occlusion curve and a 0.4 × 0.8 cm thrombosed aneurysm in the hypothenar region of the ulnar artery. The photoplethysmography recording was flat in the fourth and fifth fingers. Magnetic resonance angiography showed a distal ulnar artery aneurysm with the absence of the deep palmar arch and the arteriography scan revealed the presence of a thin ulnar artery with delayed opaquing. Conclusions. The clinical-imaging findings and the patient’s reporting repeated traumatic injury to the hypothenar eminence from using a personal computer led us to establish a diagnosis of atypical HHS. Clinical progress was favourable with medical treatment (low-molecular-weight heparin and analgesics) and the symptoms disappeared within the first 24 hours

ABSTRACT

Introducción. Las tumoraciones carotídeas paracervicales son una entidad rara y con una incidencia baja, sobre todo si las comparamos con las malformaciones aneurismáticas intracraneales. La localización varía en función de la etiología: sífilis, tuberculosis y otras infecciones locales fueron la causa más común hasta hace 50 años, y hoy día lo son los traumatismos y la cirugía carotídea previa. Caso clínico. Varón de 58 años con una tumoración cervical surgida tras la realización de un acceso venoso yugular temporal para hemodiálisis. Los estudios complementarios confirmaron la presencia de un pseudoaneurisma carotídeo. No hubo sintomatología neurológica o local asociada. El paciente precisó cirugía reparadora con buena evolución postoperatoria. Conclusiones. El acceso venoso yugular suele ser la vía más utilizada para el catéter temporal de diálisis por su comodidad y fácil acceso, así como por la baja incidencia de yatrogenia. Una de las complicaciones más frecuentes es la punción accidental de la arteria carótida, que no suele ser problemática, puesto que la retirada de la aguja y la compresión de la zona evitan la aparición y progresión del hematoma. Los aneurismas carotídeos son una entidad poco frecuente, y es aún menor la incidencia de pseudoaneurismas postraumáticos


Introduction. Paracervical carotid tumours are a rare condition with a low incidence, especially if we compare them with intracranial aneurysmal malformations. The location varies according to the causation: syphilis, tuberculosis and other local infections were the most common cause up 50 years ago, and today these have been replaced by traumatic injuries and previous carotid surgery. Case report. We report the case of a 58-year-old male with a cervical tumour that appeared after a temporary jugular venous access had been opened for haemodialysis. Complementary studies confirmed the presence of a carotid pseudoaneurysm. There were no associated neurological or local symptoms. The patient required restorative surgery and post-operative progress was good. Conclusions. Venous access through the jugular is usually the most commonly employed opening for a temporary dialysis catheter, due to its practical, easy access and also owing to the low rate of iatrogenic effects. One of the most frequent complications involves accidental puncture of the carotid artery, which does not usually represent a problem because withdrawal of the needle and application of pressure to the area prevent haematomas from appearing and developing. Carotid aneurysms are a rare condition and the incidence of post-traumatic pseudoaneurysms is even lower

ABSTRACT

Introducción. Con el fin de seleccionar pacientes para angioplastia carotídea, algunos estudios han fijado criteriospara definir grupos de alto riesgo. Objetivo. Analizar y comparar los resultados de la endarterectomía carotídea(EAC) según criterios de riesgo. Pacientes y métodos. Revisión retrospectiva de 669 EAC realizadas entre 1991 y 2004. Elriesgo se estratificó según los criterios NASCET y SAPPHIRE. El grupo A (alto riesgo) estuvo formado por 184 EAC(27,5%): 32 mayores de 80 años, 81 oclusiones contralaterales, ocho con enfermedad pulmonar grave –volumen espiratoriomáximo en el primer segundo (FEV1) 3 mg/dL) y 61 con cardiopatía grave(angina inestable, infarto reciente, insuficiencia cardíaca clase III/IV, fibrilación auricular o cirugía cardíaca combinada).En el grupo B (ausencia de criterios) se incluyeron 485 EAC (72,5%). Se analizaron la morbilidad neurológica y cardíacay la mortalidad perioperatorias. El análisis estadístico se realizó mediante el test de chi al cuadrado. Resultados.Para los grupos A y B la morbilidad neurológica fue, respectivamente, del 5,9 y 2,4% –p = 0,02; riesgo relativo (RR):2,41; intervalo de confianza al 95% (IC 95%): 1,08-5,37–; la morbilidad cardíaca, del 1,6 y 0,4% (NS); y la mortalidad,del 0,5 y 0,6% (NS). La morbimortalidad global (ictus, infarto de miocardio o muerte) para el grupo A fue de 8,1%, y parael grupo B, de 3,5% (p = 0,013; RR: 2,32; IC 95%: 1,18-4,56). De todos los criterios utilizados, la oclusión contralateralse correlacionó con un aumento de la morbilidad neurológica (p = 0,001; RR: 4,66; IC 95%: 2,08-10,41). Conclusión.Nuestra serie confirma que la oclusión contralateral aumenta el riesgo de ictus


Introduction. In order to select patients for carotid angioplasty, some studies have set criteria for defininghigh-risk groups. Aim. To analyse and compare the outcomes of carotid endarterectomies (CEA) according to riskcriteria. Patients and methods. We conducted a retrospective review of 669 CEA carried out between 1991 and 2004.Risk was differentiated according to the NASCET and SAPPHIRE criteria. Group A (high risk) was made up of 184(27.5%) CEAs: 32 patients over the age of 80, 81 contralateral occlusions, eight with severe lung disease –forcedexpiratory volume in the first second (FEV1) 3 mg/dL); 61 with severe heart disease(unstable angina, recent infarction, class III/IV heart failure, atrial fibrillation or combined heart surgery). Group B(absence of criteria) was made up of 485 (72.5%) CEAs. Perioperative mortality and cardiac and neurologicalmorbidity were analysed. The statistical analysis was performed by means of the chi-squared test. Results. For groups Aand B, neurological morbidity rates were 5.9% and 2.4% –p = 0.02; relative risk (RR): 2.41; 95% confidence interval(CI 95%): 1.08-5.37–; cardiac morbidity rate 1.6 and 0.4% (NS) and mortality rate 0.5 and 0.6% (NS), respectively.Overall morbidity and mortality (stroke, myocardial infarct or death) for group A was 8.1% and for group B it was 3.5%(p = 0.013; RR: 2.32; CI 95%: 1,18-4,56). Of all the criteria that were used, there was a correlation between contralateralocclusion and increased neurological morbidity (p = 0.001; RR: 4.66; CI 95%: 2,08-10,41). Conclusion. Ourseries confirms that contralateral occlusion increases the risk of a stroke

ABSTRACT

Introducción. Diversos estudios han relacionado la degeneración aórtica aneurismática con la disección previa, sobre todo en pacientes con hipertensión arterial. Objetivo. Analizar la tasa de degeneración aneurismática en los pacientes con diagnóstico previo de disección aórtica. Pacientes y métodos. Estudio observacional retrospectivo de 70 pacientes que sobrevivieron al episodio agudo de disección aórtica toracoabdominal, entre 1994 y 2003. La media de edad fue de 65,3 años. Control anual con tomografía axial computarizada. Se analizan los factores de riesgo cardiovascular, comorbilidades asociadas y estado de la falsa luz. Resultados. El seguimiento medio fue de 30 meses. Se observó degeneración en 44 pacientes (62,8%). El tiempo medio de degeneración aneurismática fue de 31,6 meses. La degeneración aneurismática fue más frecuente en la disección tipo B (67,5% frente al 57,5% tipo A). Se realizó cirugía urgente por rotura aneurismática en seis pacientes, cirugía electiva en 18 pacientes, y 20 recibieron tratamiento conservador. La hipertensión arterial –riesgo relativo (RR): 1,01; intervalo de confianza (IC) 95%: 1,1-2,4– y la permeabilidad de la falsa luz (RR: 1,88; IC 95%: 1,1-5,3) se relacionaron con la degeneración aneurismática. Se relacionaron con la degeneración en la fase aguda de la disección la edad superior a 70 años (p = 0,025) y la permeabilidad de la falsa luz (p = 0,013). Una falsa luz permeable (RR: 9,6; IC 95%: 1,2-91,1) y el diámetro aórtico mayor de 5 cm (RR: 1,3; IC 95%: 1,1-1,6) son factores predictivos de rotura. Conclusiones. Existe una alta tasa de degeneración aneurismática en la disección con afectación aórtica toracoabdominal, respecto a la que la hipertensión arterial y la permeabilidad de la falsa luz son los principales factores relacionados (AU)


Introduction. A number of studies have related aneurysmal aortic degeneration to prior dissection, above all in patients with arterial hypertension. Aim. To analyse the rate of aneurysmal degeneration in patients previously diagnosed with aortic dissection. Patients and methods. We conducted a retrospective observational study involving 70 patients who survived an acute episode of thoracoabdominal aortic dissection between 1994 and 2003. Mean age was 65.3 years. Patients were submitted to annual controls using computerised axial tomography scans. Cardiovascular risk factors, associated comorbidities and the false lumen status were all analysed. Results. Mean follow-up time was 30 months. Degeneration was observed in 44 patients (62.8%). The mean time of aneurysmal degeneration was 31.6 months and was more frequent in type B dissections (67.5 versus 57.5% in type A). Urgent surgical treatment was performed to treat aneurysmal rupture in 6 patients, 18 patients were submitted to elective surgery and 20 patients received conservative treatment. Arterial hypertension –relative risk (RR): 1.01; 95% confidence interval (CI): 1.1-2.4– and false lumen patency (RR: 1.88; CI 95%: 1.1-5.3) were related to aneurysmal degeneration. An age above 70 years (p = 0.025) and false lumen patency (p = 0.013) were linked to degeneration in the acute phase of the dissection. A false lumen patency (RR: 9.6; CI 95%: 1.2-91.1) and an aortic diameter above 5 cm (RR: 1.3; CI 95%: 1.1-1.6) are factors predicting rupture. Conclusions. The rate of aneurysmal degeneration in dissection involving the thoracoabdominal aorta is high: arterial hypertension and false lumen patency are the main related factors (AU)

ABSTRACT

BACKGROUND AND OBJECTIVE: Our objective was to assess the effect of renal revascularization on renal function and blood pressure control. PATIENTS AND METHOD: Retrospective analysis of primary renal revascularization procedures performed during a 6-year period. Parameters of renal function and blood pressure control were assessed before and after the procedure. RESULTS: Forty consecutive renal artery revascularizations were performed in 36 patients (12 aorto-renal bypasses and 28 percutaneous transluminal angioplasties, 4 bilateral). At the first month, the renal function improved in 50% cases, but at the mean follow-up it improved only in 26%. At the first month, blood pressure control improved in 50% patients, but at the mean follow-up, it only improved in 28%. CONCLUSIONS: Renal revascularization does not offer a medium-term benefit in most patients.

ABSTRACT

FUNDAMENTO Y OBJETIVO: Conocer el efecto de la revascularización renal sobre el control de la presión arterial y la función renal. PACIENTES Y MÉTODO: Se analizaron retrospectivamente las revascularizaciones renales realizadas durante 6 años. Se valoraron parámetros de función renal y del control de la presión arterial pre y posprocedimiento. RESULTADOS: Se realizaron 40 procedimientos en 36 pacientes (12 derivaciones aortorenales y 28 angioplastias, 4 bilaterales).Al primer mes del seguimiento la función renal mejoró en el 50 por ciento de los casos, pero al final del seguimiento medio sólo mejoró en el 26 por ciento. El control de la presión arterial mejoró al primer mes del tratamiento en el 50 por ciento de los pacientes, pero al final del seguimiento medio sólo mejoró el 28 por ciento. CONCLUSIONES: A medio plazo la revascularización renal no aporta ningún beneficio sobre el control de la presión arterial y de la función renal en la mayoría de los pacientes. (AU)

ABSTRACT

Introducción. La utilización de catéteres implantados para la administración de quimioterapia es cada vez más frecuente. El síndrome del pellizco costoclavicular (SPCC) es una rara complicación de dichos catéteres, produce la obstrucción y finalmente la sección del catéter, y su eventual embolización a cavidades cardíacas derechas o a arterias pulmonares. Casos clínicos. Se presentan los casos de dos pacientes portadoras de sistemas reservorio-catéter implantados por vía subclavia que presentaron dicha complicación. El primer caso es una mujer de 42 años a la que se le implantó un sistema reservorio-catéter para la administración de quimioterapia adyuvante por una neoplasia de mama. A las seis semanas de su colocación se detectó su obstrucción y se retiró a las 15 semanas. Durante su retirada la porción proximal del catéter se fragmentó y quedó alojada en el ventrículo derecho, se extrajo por vía percutánea. El segundo caso es una mujer de 60 años en tratamiento paliativo por una neoplasia de mama diseminada. A las diez semanas de tratamiento, la paciente inició dolor infraclavicular durante la administración de la quimioterapia. En la radiografía, realizada con administración de contraste, se observó la extravasación del mismo. En el momento de su retirada se objetivó la sección parcial del catéter. Conclusiones. El SPCC es una complicación infrecuente de los catéteres implantados por vía subclavia. En este trabajo se describe dicha complicación, su incidencia, sus signos diagnósticos y las medidas sugeridas para evitarlo (AU)
