Abstract

Surgical treatment of toracoabdominal aortic aneurysms (TAAA) represents a difficult problem for the vascular surgeon and may become a formidable challenge in an emergency procedure. In patient with hemodynamic instability, protective measures as cerebral spinal fluid drainage and bio-pump against spinal cord, visceral and renal ischemia, may be ineffective or impracticable. We report our experience of 51 emergency-operated patients with TAAA out of 660 treated between 1994 and 2014; 48 patients (94%) were hemodynamically unstable, 3 (6%) were hemodynamically stable. The TAAA patients were evaluated, according to Crawford classification, as: 18 type I, 13 type II, 15 type III, 5 type IV. Overall mortality was 23 cases out of 51 (43.1%); 8 deaths occurred during the surgical procedure and 14 in the postoperative period. Early deaths, subdivided by Crawford TAAA classification, were: type I 9/18 (50%), type II 9/13 (69.2%), type III 7/15 (46.6%), type IV 3/5 (60%). Paraplegia-paraparesis developed in 6 cases out of 43 (16.2%), excluding 8 deaths during the operative procedure. Acute renal failure was observed in 8 out of 43 patients (18.6%). Dialysis was found to be a risk factor for hospital mortality (p = 0.03). Pulmonary insuf...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.
