Abstract

Arteriosclerotic aneurysm of the thoracoabdominal aorta, involving one or more visceral branches, was successfully operated on in eight patients. Two of the aneurysms had ruptured. The left diaphragm-splitting thoracoabdominal incision through the 8th intercostal space, using a retroperitoneal route, gave unrestricted exposure. A temporary aortofemoral shunt effectively protected abdominal organs and spinal cord from perioperative ischemic damage. The step-by-step reattachment technique into ready-made side limbs in the woven Dacron graft ensured that visceral and renal ischemic times remained within acceptable limits. Perfusion cooling of the abdominal organs was done in one patient in whom shunt could not be used. A standby autotransfusion device was life-saving in another case. All the patients recovered without major complications. Moderate elevation was found as regards serum creatinine levels in seven patients and liver enzymes in four patients, but the values normalized within a month. No paraplegic complications occurred, although all bleeding intercostal and lumbar arteries were ligated intra-aneurysmatically in seven of the eight patients. Seven patients are well 20 to 60 months postoperatively, with patent and well f...Continue Reading

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
