Heart - Coronary Artery Stents and Cosmetic Surgery

Heart (coronary) artery blockage is a local blocking or narrowing in the arteries on the outer surface of the heart by accumulated deposits of plaque, which is mostly bad cholesterol. Every artery in the body is a blood pipeline. These pipelines get blocked with accumulation of bad cholesterol. When a cardiologist suspects blockage or narrowing of any of these heart arteries he/she will perform an angiography (threading a catheter up a thigh artery to the heart to inject a dye that is visible on X-ray) to view the inside of the arteries. When an area of artery narrowing or blockage is identified a catheter with a balloon is inserted along the same path and inflated at the problem area to open it up. This is called angioplasty. Increasingly stents are placed at these angioplasty sites to keep them open in the long term. In some cases multiple stents are sequentially placed in the same artery. If the area cannot be treated in such a fashion open heart surgery is required which involves …

Blood Clots, Venous Thromboembolism, Pulmonary Embolus and Cosmetic Surgery

In a previous blog I discussed Bleeding Disorders and Cosmetic Surgery focusing on bleeding tendencies and abnormally low blood clotting. This blog deals with the other side of the coin abnormally high blood clotting. These clots usually form in large veins of the leg or pelvis or in the chambers of diseased hearts.

Because these clots form in a direct pipeline to the heart and lungs without an intervening bed of capillaries to filter out large clots they can be life threatening when they travel up to and get stuck in the hear or lungs, especially when large in size. The chance of this occurring in otherwise normal patients during any surgery under general anesthesia is reduced by applying pneumatic compression devices on the legs to pump venous blood back up to the heart during surgery as stagnant blood is clotting blood. A multitude of factors such as traumatic injuries, cancer, reaction to certain medications (birth control pills) etc can cause or provoke the initial clot formation.…
