Cholesterol crystal embolization (CCE) may be triggered by various factors: intra-arterial angiographic procedures, aortic or vascular surgery, anticoagulant or thrombolytic treatments, or both. There are few previous reports of patients undergoing coronary artery bypass grafting (CABG) experiencing and therefore displaying severe systemic CCE. We describe four patients presenting, shortly after ...
Marzelle J - - 1996
Angioscopy has been used in the superficial femoral artery for many years, as well as in the control of vascular surgery procedures. It is more reliable than angiography, which often misses such features as intimal flaps, residual valves in "in situ" vein bypasses or persisting thrombus after embolectomy. As fluid ...

Angioscopy is part of a new armoury of minimally invasive 'keyhole' surgery. Like other 'scopes' it enables the surgeon to have a direct view of the interior of the body with greatly reduced surgical intervention. An angioscope is an ultra thin multi-bundle fibre scope which has manual flexibility. Its tiny ...
Meer, Jannes van der
Coronary artery bypass surgery has improved the quality of life in patients with severe disabling angina. A favourable effect on life expectanca has been demonstrated only in a subgroup of these patients. The results of surgery have been improved with time, mainly due to changes in surgical technique, like the ...

Hurley J P - - 1993
A 59-year-old chronically hypertensive patient developed "man-in-the-barrel syndrome" following urgent coronary artery bypass graft surgery (CABG). This syndrome describes a brachial diplegia with intact motor function of the legs. Magnetic resonance imaging confirmed areas of ischaemia consistent with hypoperfusion leading to border-zone infarction between the territories of the anterior and ...
Kahn J K - - 1993
We report a case of failed coronary angioplasty requiring urgent coronary artery bypass graft surgery. The return of angina pectoris early after surgery led to repeat catheterization, demonstrating a rapidly progressive stenosis of the left main coronary artery. This was treated successfully with coronary angioplasty. In patients with recurrent angina ...
Lewis R W - - 1993
Coronary bypass surgery to provide better blood flow to deficient areas of the heart is commonplace; the arteries of the heart in which blockage occurs are relatively large, and rerouting of blood is readily accomplished. In the penis, the internal pudendal system that provides arterial inflow can be easily bypassed ...
