Operative management of aortoiliac occlusive disease in presence of horseshoe kidney: report of a case

چکیده
Coexistence of aortoiliac arteriosclerosis with horseshoe kidney in a 57-year-old man is presented. Diagnosis of this unusual combination was made shortly before surgery. Magnetic resonance angiography is the most important preoperative diagnostic tool for surgical planning. A trans-abdominal approach provides excellent exposure of the abdominal aorta in patients with a horseshoe kidney without risk of injury to renal accessory arteries or to a ureter in an anomalous position. Implantation of an aorto-bifemoral Y prosthesis was made using a Dacron bifurcation. By diffuse atherosclerotic lesion and in presence of horseshoe kidney, an end-toside proximal anastomosis of the aorta was carried out. Descriptors: Iliac artery, surgery. Arteriosclerosis. Kidney, abnormalities. Resumo Neste trabalho é apresentado um caso de coexistência de aterosclerose aorto-ilíaca com rim em ferradura, em um homem com 57 anos de idade. O diagnóstico desta combinação rara foi feito pouco antes da cirurgia, com a angio-ressonância magnética constituindo o método diagnóstico pré-operatório mais importante para o planejamento cirúrgico. A abordagem transabdominal proporciona uma exposição excelente da aorta abdominal em pacientes com rim em ferradura, sem risco de lesão das artérias renais acessórias ou de ureter em posição anômala. A reconstrução foi feita com a implantação de uma prótese de Dacron em Y em posição aorto-bifemoral e, por causa da lesão aterosclerótica difusa e na presença do rim em ferradura, foi optado por anastomose proximal términolateral.

Horseshoe Placenta and Preterm Labour: A Case Report
Background and aim: Horseshoe placenta is a variant of ring-shaped placenta. Ring-shaped placenta is a rare anomaly seen in fewer than 1 in 6000 deliveries, which could be seen as horseshoe shape due to atrophy in a portion of the ring. This report refers to a possible relationship between the horseshoe shape placenta and preterm labor; although it has not been yet validated in the literature. ...

Surgical management of advance aortoiliac occlusive disease is time-tested and a widely practiced strategy, particularly when there is significant coronary artery disease associated with aortoiliac occlusive disease. The technological advances in the field of percutaneous techniques have facilitated the use of nonsurgical endovascular alternatives for peripheral arterial disease in patients wit...
متن کاملAnterior Rectal Resection in a Patient with Aortoiliac Occlusive Disease and Coexisting Collateral Pathways: Management and Pitfalls
Chronic aortoiliac occlusive disease most often affects the common iliac arteries and distal aorta but can progress all the way to the renal arteries, occluding the inferior mesenteric artery. A compensatory collateral network typically develops to preserve lower body perfusion. Inadvertent compression or ligation of such collaterals during surgery can have catastrophic consequences. In this ar...

We present a rare case of a patient with aortoiliac occlusive disease on the background of type A crossed renal ectopia, for whom open surgical intervention was required. Aortic exposure in patients with concomitant crossed renal ectopia can present technical challenges to the vascular surgeon. The knowledge of variations in the ectopic renal blood supply is of paramount importance when perform...
