Midline one-stage complete unifocalization and repair of pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals.
Traditionally patients with pulmonary atresia, ventricular septal defect, diminutive or absent central pulmonary arteries, and multiple aortopulmonary collaterals have been managed by staged procedures necessitating multiple operations. We have taken a different approach to this lesion. Between August 1992 and March 1994, ten patients aged 1.43 months to 37.34 years (median 2.08 years) at the severe end of the morphologic spectrum of this lesion underwent a one-stage complete unifocalization and repair from a midline sternotomy approach. ⋯ One other patient underwent balloon dilation of the reconstructed right pulmonary artery, with a good result. All survivors (9/10) are clinically doing well. This approach establishes normal cardiovascular physiology early in life, eliminates the need for multiple systemic-pulmonary artery shunts and use of prosthetic material, and minimizes the number of operations required.(ABSTRACT TRUNCATED AT 400 WORDS)

Axillary artery: an alternative site of arterial cannulation for patients with extensive aortic and peripheral vascular disease.
The increasing number of patients with extensive aortic and peripheral vascular atherosclerosis or aneurysms who are undergoing cardiac operations present difficult decisions as to the optimal site of arterial cannulation for cardiopulmonary bypass. Femoral artery cannulation is the most common alternative to ascending aortic cannulation, but severe iliofemoral disease or the danger of atheroemboli caused by retrograde perfusion through an atherosclerotic or aneurysmal descending aorta may make this approach impossible or undesirable. We have used axillary artery cannulation for cardiac operations in 35 patients for indications including severe aortic atherosclerosis (n = 16), extensive aortic aneurysms (n = 11), and aortic dissection (n = 8). ⋯ Four patients died in the hospital. We conclude that axillary artery cannulation is a safe and effective means of providing antegrade arterial flow during cardiopulmonary bypass in patients with severe atherosclerotic or aneurysmal disease. This strategy may lower the prevalence of stroke associated with cardiopulmonary bypass in these patients.
