The latest news on new surgical techniques involves a radical new life-saving pinhole surgery that was successfully performed at the American Hospital in Dubai by a team of highly skilled specialists led by consultant interventional cardiologist, Dr Omar Kamel Hallak. The surgery aimed at repairing the largest artery in the body, using complex stenting techniques. Stenting typically involves inserting tubes known as stents into the arteries. These tubes that are inserted do the function of supporting the walls of the arteries.  

In the operating theatre, Jodhpur, India Dr. Hallak and his team used an interventional cardiology procedure known as stenting to repair the abdominal aorta. The abdominal aorta, which is the largest artery in the body, is about the size of a garden hosepipe. 

According to a statement released by Dr. Hallak, endovascular repair or stenting is a common procedure in interventional cardiology where it is used to repair coronary arteries. He and his multidisciplinary team used their experience and expertise in this procedure across new surgical areas breaking the barriers that have so far restricted the use of this technique to other applications.

This minimally invasive surgical procedure, which lasts around two hours, dramatically reduces the risk to the patient and leaves little or no scarring, while also speeding up the recovery process.

Patients for this procedure are selected very carefully as it is not suitable for every individual. Suitability and success of the process is dependent on the size as well as the position of the aneurysm or ballooning. Aneurysms can occur in any artery but they most commonly occur in the aorta. These are called Abdominal Aortic Aneurysms (AAA). The normal diameter of the aorta in the abdomen is about 20 mm but with an aneurysm a section of the aorta within the abdomen is 30 mm or more in diameter. These patients are at risk of the aortic artery rupturing due to the aneurysm, which is often lethal.

Abdominal Aortic Aneurysms can vary greatly in size and location. Usually, once they develop, they keep growing and getting larger in size. The growth rate is typically about 10 % per year. As the size increases, so does the risk of it rupturing. The repair is usually done when the size of the AAA is larger than 55 mm.

So far, the results for patients that have been treated using this procedure have been excellent. Most patients have just needed an overnight stay in hospital and are discharged the day after surgery.
