Abstract

The number of patients with thoracic aortic aneurysm has been increasing in Japan. The annual report by the Japanese Association for Thoracic Surgery 2001 demonstrated that 4,133 patients underwent surgery for thoracic aortic aneurysm. Among them, ruptured cases consisted of 11% (460 patients) and its early mortality was 32%. At the emergency room, initial accurate diagnosis, using echocardiography and computed tomography (CT), is mandatory for the next step and catastrophic shock status should be corrected if possible, such as pericardiocentesis or transfusion. For patients with ruptured descending or thoracoabdominal aortic aneurysms, the endovascular stent-grafting should be first choice of treatment. Otherwise, patients should be sent for the operation room as quickly as possible for initialing cardiopulmonary bypass and for controlling bleeding. Special attention should be paid for not injuring the left lung after left thoracotomy. Mycotic false aneurysms, including the aorto-esophageal fistula and prosthetic graft infection, remained as one of challenging entities in aortic emergency. The standard treatment for this fatal disease resection of the infected both aneurysm and esophagus, and has been reconstruction with an ex...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.
