ABSTRACT
INTRODUCTION AND OBJECTIVES: Platelet-rich plasma (PRP) is used as an adjuvant in the treatment of chronic ulcers of the lower extremity and has shown particularly promising results in the case of neuropathic ulcers. There has been less research, however, into its use in venous and hypertensive ulcers. Our aim was to assess the safety and feasibility of using PRP in the treatment of chronic ulcers of the lower extremity and to evaluate its potential benefits in directed healing. MATERIAL AND METHODS: We prospectively selected 11 patients with nonischemic ulcers of the lower extremity that had been present for at least 6 weeks. PRP was injected subcutaneously into the perilesional tissue and applied topically in 4 sessions held at 1-week intervals. We assessed quality of life (SF-12 questionnaire), pain (visual analog scale), and the circumference of the ulcer before and after treatment. RESULTS: There was a predominance of women (8/11, 73%), and venous ulcers (7/11, 64%) were more common than hypertensive ulcers (4/11, 36%). The median age of the patients was 79 years and the median time since onset of the ulcer was 17 months (range, 6-108 months). We observed a significant reduction in pain (P<.05) and a significant improvement in the physical and mental components of the SF-12 (P<.05). The mean reduction in ulcer size was 60%, and complete healing was achieved in 5 cases. No adverse effects were observed. CONCLUSION: The local application of PRP is a valuable and practical procedure that promotes the healing of chronic ulcers of the lower extremity; it can improve patient quality of life and is particularly effective in local pain relief.

Objetivo: Analizar nuestra experiencia y resultados obtenidos en una patología infrecuente, compleja y grave como la fístula aortoentérica (FAE). Material y métodos: La patología aórtica previa y su tratamiento fueron: 4 síndromes de Leriche y 2 aneurismas de aorta y un aneurisma roto tratados con bypass aortobifemoral y dos endovascular aneurysms repair (EVAR). Otros datos recogidos fueron: factores de riesgo cardiovascular, patología y cirugía abdominal previa, la localización de FAE secundaria, periodo de tiempo hasta la FAE, evolución y recidivas. Nueve pacientes (7 hombres y 2 mujeres) con fístula secundaria aortoentérica tratados durante el periodo 2000-2010 se agruparon en función de la estabilidad hemodinámica: 3 hombres estables, 4 hombres y 2 mujeres inestables. Resultados: Las FAE secundarias aparecieron tras una media de tiempo de 85,8 meses (mediana: 104; rango: 5-204). Cuatro se trataron con bypass extra-anatómico, 3 inestables. Tres pacientes con reparación in situ, 2 inestables. Dos de forma endovascular, uno inestable. Hubo una muerte intra-quirófano, inestable, y durante los primeros 30 días fallecieron otros 4 pacientes, 3 inestables y uno estable. Los 4 pacientes que sobrevivieron sufrieron una recidiva de la FAE tras tres meses de media (intervalo: 2-5); solo dos se trataron, uno con endoprótesis y otro con bypass axilobifemoral. Conclusiones: La FAE secundaria es una complicación grave, rara y compleja, con una alta morbilidad y mortalidad. No existe un tratamiento estándar, aunque es fundamental el tratamiento urgente de la hemorragia, incluyendo la terapia endovascular, con o sin una nueva intervención para el tratamiento definitivo(AU()
Objective: To analyse our experience and results of a rare, complex and serious disease, aortoenteric fistula (AEF). Material and methods: Nine patients (seven males and two females) with secondary aortoenteric fistula treated during the period 2000-2010, were grouped according to hemodynamic stability: stable three males. Four males and two females were unstable. Previous aortic pathology and its treatment were: four Leriche syndrome, two aortic aneurysms and a ruptured aortic aneurysm treated by aortobifemoral bypass and two EVAR (endovascular aneurysms repair). Other data collected: cardiovascular risk factors, previous abdominal pathology and its surgery, the location of the secondary AEF, period of time until the appearance of AEF, evolution and recurrence. Results: The secondary AEF appeared after a mean time of 85.8 months (median 104, range 5-204). Four were treated with extra-anatomical bypass, and three were unstable. Three patients with in situ repair, two unstable. Two with endograft, one unstable. There was one death during surgery, unstable, and during the first 30 days, four patients died, 3 unstable, one stable. The four surviving patients had a recurrence of the AEF after a mean of three months (range, 2-5), only two were treated, one patient with endograft and one with axilobifemoral bypass. Conclusions: Secondary AEF is a serious, rare and complex complication, with high morbidity and mortality. No standard treatment exists, although the urgent treatment of bleeding is essential, including endovascular therapy, with or without a new intervention for definitive treatment(AU)

Introducción. La leiomiomatosis intravenosa (LIV) es un tumor poco frecuente que puede crecer a través devena cava inferior hasta extenderse a las cavidades cardíacas derechas. Es un tumor originado por las células de músculoliso y normalmente se encuentra confinado al sistema venoso pélvico. Se han descrito no más de 100 casos de LIV,de los cuales, tan sólo 30 presentaban afectación cardíaca. Aunque histológicamente es benigno, la afectación de las cavidadescardíacas derechas puede producir síntomas graves como síncopes y arritmias, y en algunos casos puede llegara producir la muerte súbita. Caso clínico. Mujer de 40 años con extensión cardíaca y que no presentaba síntomas previos.La extensión del tumor se producía tanto por ambas venas ilíacas internas como por la vena ovárica izquierda, algo quetan sólo se había descrito en otros dos casos anteriormente. La escisión quirúrgica se realizó en un único tiempo quirúrgicomediante circulación extracorpórea y abordaje abdominal y torácico. Conclusión. A pesar de ser un tumor poco frecuente,el retraso en la presentación de los síntomas (incluso 20 años) puede infravalorar su incidencia. Dado el gravecuadro clínico que puede provocar, su tratamiento es en todos los casos la extirpación quirúrgica, lo que supone un importantereto para el cirujano vascular. La escasa incidencia de la LIV y el tipo de extensión del tumor en este caso clínicolo hacen realmente excepcional
Introduction. Intravenous leiomyomatosis (IVL) is a rare tumour that may spread along the inferior venacava until it reaches the cavities on the right-hand side of the heart. It is a tumour that has its origins in smooth musclecells and is normally restricted to the pelvic venous system. No more than 100 cases of IVL have been reported, of whichonly 30 presented cardiac involvement. Although histologically it is benign, the involvement of the right cavities of theheart can give rise to severe symptoms such as syncopes and arrhythmias and in some cases it can even lead to suddendeath. Case report. A 40-year-old female with extension to the heart and who had no previous symptoms. The tumourspread along both the internal iliac veins and the left ovarian vein, something which had only previously been reportedin two other cases. Surgical excision was performed in a single session of surgery by means of a heart-lung bypass andusing an abdominal and thoracic approach. Conclusions. Despite being an infrequent tumour, its incidence may beunderestimated due to the fact that its symptoms often appear very late on in the course of the disease (up to 20 years).Given the severe clinical features that it may cause, its treatment always involves surgical removal, which is animportant challenge for the vascular surgeon. The low incidence of IVL and the type of extension of the tumour in thiscase make it truly exceptional

Introducción. Los pseudoaneurismas de la arteria peronea son una patología rara asociada a traumatismos de la pierna, a cirugía traumatológica o a lesiones de la pared arterial secundarias a embolectomía con balón. Pueden ser asintomáticos o, por el contrario, debutar con dolor y sensación de masa, lo que puede asociar una fístula arteriovenosa o un síndrome compartimental. El tratamiento endovascular mediante embolización representa una solución novedosa a este tipo de lesiones. Caso clínico. Mujer de 71 años que con el diagnóstico de isquemia arterial aguda en el miembro inferior derecho de probable origen cardioembólico fue intervenida de tromboembolectomía transfemoral derecha; recuperó los pulsos distales y fue dada de alta a los cinco días de la intervención. Acudió al servicio de urgencias a los 10 días del alta con clínica de dolor en la región aquílea del miembro inferior derecho y edema, y mediante eco-Doppler se diagnosticó un pseudoaneurisma de la arteria peronea derecha. Se le realizó arteriografía a través de la arteria femoral contralateral; se cateterizó selectivamente la arteria peronea, que confirmó la presencia del pseudoaneurisma, y se procedió a su embolización con coils
Introduction. Pseudoaneurysms of the fibular artery are a rare pathological condition associated with traumatic injuries to the legs, trauma surgery or lesions in the walls of the artery secondary to balloon embolectomies. They can be asymptomatic or, in contrast, they may begin with pain and the presence of a mass, which can be associated to an arteriovenous fistula or compartment syndrome. Endovascular treatment by embolisation is a novel solution to this type of lesion. Case report. We report the case of a 71-year-old female who was diagnosed as having acute arterial ischaemia in the lower right limb that probably had cardioembolic origins; the patient was submitted to a right transfemoral thromboembolectomy. Distal pulses were restored and she was discharged from hospital five days after the operation. She visited the emergency department again 10 days after discharge with symptoms of pain in the Achilles region of the right lower limb and oedema; Doppler ultrasound recording was used to reach a diagnosis of pseudoaneurysm of the right fibular artery. Arteriography was performed through the contralateral femoral artery; the fibular artery was selectively catheterised, which confirmed the presence of a pseudoaneurysm and this was then embolised using coils
