Artéria axilar na instalação de circulação extracorpórea: indicações e resultados

Abstract

Objectives: To determine indications and results of axillary artery cannulation for cardiopulmonary bypass.Methods: From January 2005 through December 2008, axillary artery cannulation was used in 48 patients. Mean age was 62 ±11 years and 33 patients (69%) were males. Axillary artery was approached by infraclavicular incision and the cannula introduced in a 8 millimeter Dacron side graft.Results: Indications were calcified aorta (N=18, 38%), aortic dissection (N=15, 31%), ascending and/or aortic arch aneurysm (N=11, 23%) and prior to reoperative median sternotomy (N=4, 8%). Changes in intraoperative planning occurred most often in patients with calcified aorta (100% versus 10%, P<.0001) than in patients with other indications, which follow their preoperative plan. Cardiopulmonary bypass (deep hypothermic circulatory arrest in 55% and conventional in the remaining) was uneventfully conducted in all patients but one (success rate 98%) due to undiagnosed inominate artery stenosis. Local complication was lymphatic drainage in three patients (6.2%). Bras Cir Cardiovasc 2009; 24(3): 404-408 Conclusions Rev

A review of cardiopulmonary research in Brazilian medical journals: clinical, surgical and epidemiological data

“…Coronary artery bypass surgery was the topic of four separate studies: Atik et al described indications for and results of the use of the axillary artery for cardiopulmonary bypass 35. Brito et al surveyed risk factors for the development of acute renal failure following cardiopulmonary bypass 36.…”
