Liberal use of axillary artery cannulation for aortic and complex cardiac surgery.

Objectives: Axillary artery cannulation for cardiopulmonary bypass has been described previously as a safe and reliable technique, with a low risk of atheroemboli, avoidance of malperfusion in aortic dissection and facilitation of selective antegrade cerebral perfusion during hypothermic circulatory arrest. The aim of this study was to document the broad applicability of axillary cannulation and its associated morbidity and identify where it was not possible to use planned axillary cannulation.
Methods: A retrospective review of a single surgeon's 10-year experience of axillary cannulation using the side-graft technique in 184 consecutive patients (age 22-92 years) in aortic and complex cardiac surgery from July 2002 to June 2012.

Aortic plaques are a manifestation of the general process of atherosclerosis in which there is a progressive accumulation of cholesterol and other lipids in the intimal-medial layer of the aorta with secondary inflammation, repetitive fibrous tissue deposition, and eventually luminal surface erosions and appearance of often mobile thrombi protruding into the lumen of the aorta. Aortic plaques may give rise to two types of emboli: thromboemboli and atheroemboli (cholesterol crystal emboli). Thromboemboli are relatively large, tend to occlude medium to large arteries, and cause strokes, transient ischemic attacks, and renal infarcts and other forms of peripheral thromboembolism.

Background: Cannulation of the axillary artery for cardiopulmonary bypass (CPB) avoids manipulation of an atherosclerotic, aneurysmal, or dissected ascending aorta. Advantages include: low risk of atheroemboli, low risk of malperfusion in dissections, and facilitates selective antegrade cerebral perfusion (SACP) during hypothermic circulatory arrest (HCA).
Methods: A single surgeon's seven year experience of axillary cannulation using the side-graft technique in 116 consecutive patients (age 22-87 years) in aortic and cardiac surgery where the ascending aorta was unapproachable.

Long-term follow-up of renal artery stenting in an Australian population.
Heart Lung Circ
April 2007
Cardiology Department, St. Vincent's Hospital, Sydney, NSW, Australia.
Background: Renal artery stenosis comprises both atherosclerotic renovascular disease and fibromuscular dysplasia, and may be associated with refractory hypertension, acute 'flash' pulmonary oedema and renal failure. The long-term clinical effects of renal artery stenting remain unclear.
Aim: To assess the procedural and long-term safety and efficacy of renal artery stenting and its effect on blood pressure, antihypertensive medication usage and serum creatinine.
