Summary

Introduction. Conventional surgical correction of aortoiliac aneurysmal pathologies in patients who have undergone a pelvic renal transplant implies a high risk of renal ischemia during aortic clamping. Endovascular repair minimises such a risk and does not require additional manoeuvres in order to preserve renal flow. Case report. A 67-year-old male, exsmoker, with hypertension, dyslipidemic, hyperuricemic, with cardiac insufficiency, ischemic heart disease, triple coronary artery bypass, a kidney transplant (allograft in the left iliac fossa), bilateral mesh inguinal and umbilical herniorrhaphy that presented a 4.5cm long infrarenal aortic aneurysm (AAA) and a 3.7cm long aneurysm in the right iliac artery (AAID), both of which were asymptomatic. Given the need to operate on the AAID, together with the coexistence of the AAA and the kidney transplant, it was decided that endovascular repair should be carried out. Under general anaesthetic and systemic heparinisation, an aortoiliac bifurcated Talent ®stent was inserted, the right hypogastric artery was occluded and the patency of the left artery and the anastomosis of the renal transplant were maintained. In the immediate post-operative period no deterioration in kidney functioning was observed. The patient was discharged from hospital five days after the intervention with double antiplatelet treatment (clopidogrel 75mg and ASA 125mg). After 8 months of clinical, analytical and radiological (computerised tomography and simple X-rays) follow up, the renal graft remained patent with normal kidney functioning. Conclusions. The main benefit to be derived from aneurysmal endovascular repair in pelvic renal transplants lies in the absence of clamping and the speed and ease with which it can be performed, as compared with the manoeuvres aimed at preserving renal flow used in conventional surgery. For this reason, in the case of suitable anatomies, endovascular repair must be taken into account as one of the preferred treatments. [ANGIOLOGÍA 2004; 56: 579-86]

Resumen

Introducción. La corrección quirúrgica convencional de la patología aneurismática aortoilíaca en pacientes con trasplante renal pélvico supone un elevado riesgo de isquemia renal durante el clampaje aórtico. La reparación endovascular minimiza dicho riesgo, y no precisa maniobras adicionales para preservar el flujo renal. Caso clínico. Varón 67 años, ex fumador, hipertenso, dislipémico, hiperuricémico, con insuficiencia cardíaca, cardiopatía isquémica, triple bypass aortocoronario, trasplante renal (aloinjerto en fosa ilíaca izquierda), herniorrafía inguinal bilateral y umbilical con malla, que presenta un aneurisma de aorta infrarrenal (AAA) de 4,5cm y aneurisma de arteria ilíaca derecha (AAID) de 3,7cm asintomáticos. Dada la necesidad de intervenir el AAID, junto a la coexistencia del AAA y el trasplante renal, se decide realizar una reparación endovascular. Bajo anestesia general y heparinización sistémi-ca, se coloca endoprótesis Talent ® bifurcada aortoilíaca, se ocluye la arteria hipogástrica derecha, y se mantiene permeable la izquierda y la anastomosis del trasplante renal. En el postoperatorio inmediato no se aprecia empeoramiento de la función renal. Se da de alta al paciente con doble antiagregación (clopidogrel 75mg y AAS 125mg) al quinto día postoperatorio. A los 8 meses de seguimiento clínico, analítico y radiológico (to-mografía computarizada y radiografía simple), el injerto renal sigue permeable con función renal normal. Conclusión. El principal beneficio de la reparación endovascular aneurismática en trasplantes renales pélvicos reside en la rapidez, ausencia de clam-paje y en la facilidad de realización, en comparación con las maniobras de preservación flujorrenal en cirugía convencional. Por este motivo, en caso de anatomías favorables, debe considerarse la reparación endovascu-lar como uno de los tratamientos de elección. [ANGIOLOGÍA 2004; 56: 579-86]

Resumo

Introduçõo. A correcçõo cirúrgica convencional da patologia aneurismática aortoilíaca em doentes com transplante renal pélvico supoe um elevado risco de isquemia renal durante a clampagem aórtica. A reparaçõo endovascular minimiza o referido risco, e não precisa de manobras adicionais para preservar o fluxo renal. Caso clínico. Homem de 67 anos, ex-fumador, hipertenso, dislipidémico, hiperuricémico, com insuficiencia cardíaca, cardiopatia isquémica, triplo bypass aortocoronário, transplante renal (aloenxerto na fossa ilíaca esquerda), herniorrafia inguinal bilateral e umbilical com prótese, que apresenta um aneurisma da aorta infra-renal (AAA) de 4,5cm e aneurisma de artéria ilíaca direita (AAID) de 3,7cm assintomáticos. Dada a necessidade de intervir no AAID, juntamente com a coexistencia do AAA e do transplante renal, foi decidido realizar-se uma reparaçõo endovascular. Sob anestesia geral e heparinizaçõo sistémica, foi colocada a endoprótese Talent ® bifurcada aortoilíaca, ocluindo-se a artéria hipogástrica direita, e mantendo-se permeável a esquerda e a anastomose do transplante renal. No pós-operatório imediato não se verifica deterioracao da função renal. Tem alta, com dupla anti-agregação (clopidogrel 75mg e AAS 125mg), ao quinto dia de pós-operatório. Aos 8meses de segui-mento clínico, analítico e radiológico (tomografia computorizada e radiografia simples), o enxerto renal continua permeável com funçõo renal normal. Conclusão. O principal beneficio da reparaçõo endovascular aneu-rismática em transplantes renais pélvicos reside na rapidez, ausencia de clampagem e na facilidade de realização, em comparacao com as manobras de preservação do fluxo renal na cirurgia convencional. Por este motivo, em caso de anatomias favoráveis, deve ser considerada a reparação endovascular como um dos tratamentos de eleição. [ANGIOLOGÍA 2004; 56: 579-86]
