Results of Coronary Angiography Rafter CABG: Comparison Between No-touch and Conventional Vein Graft
Coronary Angiographical Results in Patients With Angina After CABG: Comparison Between No-touch and Conventional Vein Graft
Coronary artery disease is one of the biggest health issue worldwide: It is estimated that cardiovascular diseases cause around 45% of all death in Sweden and in the West World. The treatment, in a large part of the patients, implicates a so called bypass-operation, that consists in to connect new vascular conduits (grafts) beyond the narrowed coronary vessels to improve the blood supply to the heart. One of the graft that is commonly used is the saphenous vein from the leg. The disadvantage of the saphenous vein graft is the predisposition to early obstruction. The international literature shows the following grades of occlusion: 15% in the first year and 40% after 10 years.
At the Cardio-Thoracic Clinic of the University hospital of Örebro has been developed a new method to harvest the saphenous vein together with the surrounding fat-tissue. This technique, called no-touch technique, has the advantage to reduce the damages to the vein during the harvesting, showing a substantially reduced risk for future occlusion (5% after 18 months and 10% after 8,5 years).
2020-05-20 2020-11-16 Project created in: FoU Region Örebro län Resultat av Koronarangiografi hos patienter som tidigare CABG opererats Project number : 274418 Created by: Gabriele Ferrari, 2020-05-20 Last revised by: Gabriele Ferrari, 2020-11-16 Ongoing The aim of the PhD project is to evaluate the results of the no-touch technique in compare to the conventional technique for the venous graft harvesting. The focus of the study is to analyze all the operated patients in our clinic who underwent a post-operative coronary angiography do to angina pectoris (heart pain). One will compare the patency rate, the rate of MACE (major adverse cardiac events) and the quality of life in the two groups (no-touch vs. conventional). This study is the first and the only one in the world that will examine the long-term angiographic results of the no-touch technique in patients that had angina pectoris after the operation.
