Mics cabg or micas stands for minimally invasive coronary artery surgery. It is a relatively new and advanced technique of performing coronary bypass for coronary artery disease. In this technique the heart is approached through the side of the left chest via a small 4cm incision. This cut is placed just under the nipple. The chest is entered between the ribs without cutting any bones and by splitting the muscle.
Similar to a regular heart surgery the operation is performed using all arteries or a combination of arteries and veins removed from the leg. The vessel from the leg in these operations is also removed endoscopically without cutting the skin over the leg. Highly advanced instrumentation and advanced techniques allow for the operation to be performed very safely.
Mics cabg has several advantages over the traditional technique:
First and foremost is the fact that no bones are cut. This has several advantages in reducing pain, retaining function and having a positive effect on breathing. Unlike traditional heart surgery return to normal life including driving or other activities is not disrupted and can be started almost immediately.
Second, blood loss is almost negligible eliminating blood transfusion in most and eliminating blood borne infection.
Third, all infections are reduced whether it be wound infections or post surgical lung infection. This makes the procedure ideal in diabetics and older patients who have poor resistance to infection.
Fourth, the incision is so cosmetic and measures just 2 – 3 inches that it's practically impossible to tell that a heart operation has been done.
Fifth, the procedure lasts only 4 days unlike the conventional heart surgery that takes 9 days.
All these benefits put together make for ultra short hospitalization and recovery. The best part is that all the blocks irrespective of their location in the heart can be bypassed in a safe and predictable manner.
