RESUMEN
INTRODUCTION: Surgical treatment of renal artery aneurysms is inevitably associated with temporary renal artery occlusion and risk of ischemic injury. We present a technique for renal artery grafting and aneurysm exclusion without interrupting renal blood flow. REPORT: A symptomatic renal artery aneurysm was bypassed with a venous graft between the abdominal aorta and the very distal renal artery utilizing a distal anastomotic device without interruption of renal blood flow. The aneurysm was then excluded by means of hemostatic clips. CONCLUSION: The presented surgical technique offers the major advantage of avoiding organ ischemia and accelerating the surgical procedure.

Acute or chronic valvular diseases, acute myocardial infarction and its complications, dilated cardiomyopathies, all may became the cause of heart failure leading to different degrees of cardiogenic edema. Today cardiac failure is treated from its the early stage by medical and/or surgical therapy. Thereafter, in a small population of patients, heart failure may became unresponsive to any kind of standard medical treatment. Conventional surgical procedures are often inadequate and carry a high risk of perioperative mortality. This study analyzes the outcome of 139 patients with end-stage cardiomyopathy who underwent heart transplantation between January 1988 and October 1996. We found that patients transplanted while on severe decompensation are at a higher perioperative mortality due to irreversible multi-organ failure. The study also suggests that the implantation of a left ventricle assist device as a bridge to transplantation is a promising maneuver for the most severe patients.
