CT-angiographic Follow up of Patients That Underwent Coronary Bypass Surgery Between 1993-1997

2014-08-27 04:00:36 | BioPortfolio

Summary

Coronary artery surgery (CABG) is necessary to improve blood circulation in many patients with coronary artery disease. This is done by using alternative blood vessels (grafts) to bypass the stenosed coronary arteries. In CABG, vein grafts are traditionally used where surrounding tissue is removed, this may damage the vessel and influence its patency.

The "no-touch" technique was developed by Professor Domingos Souza at the Department of Cardiovascular and Thoracic Surgery, Örebro University Hospital. This technique includes taking out the vein with its surrounding tissue and by this way the vessel is less damaged. The first two follow ups have shown that no-touch grafts had better patency than conventionally extracted graft at 18 months and 8.5 years.

This long term follow up is a continuation of the randomized trial started in 1993 where the patency and incidence of stenoses in the no touch and conventional vein grafts has been studied.

Medical and Biotech [MESH] Definitions

Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion.

Use of a balloon catheter for dilatation of an occluded artery. It is used in treatment of arterial occlusive diseases, including renal artery stenosis and arterial occlusions in the leg. For the specific technique of balloon dilatation in coronary arteries, ANGIOPLASTY, TRANSLUMINAL, PERCUTANEOUS CORONARY is available.

Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.

A complication of INTERNAL MAMMARY-CORONARY ARTERY ANASTOMOSIS whereby an occlusion or stenosis of the proximal SUBCLAVIAN ARTERY causes a reversal of the blood flow away from the CORONARY CIRCULATION, through the grafted INTERNAL MAMMARY ARTERY (internal thoracic artery), and back to the distal subclavian distribution.

A congenital coronary vessel anomaly in which the left main CORONARY ARTERY originates from the PULMONARY ARTERY instead of from AORTA. The congenital heart defect typically results in coronary artery FISTULA; LEFT-SIDED HEART FAILURE and MITRAL VALVE INSUFFICIENCY during the first months of life.
