BACKGROUND: What is an aneurysm?
An aneurysm is an area of a localized widening (dilation) of a blood vessel. An aortic aneurysm is a general term for any swelling (dilation or aneurysm) of the aorta, usually representing an underlying weakness in the wall of the aorta at that location. Once an aneurysm reaches 5 cm. in diameter, treatment is usually considered necessary so as to prevent rupture. Below 5 cm., the risk of the aneurysm rupturing is lower than the risk of conventional surgery in patients with normal surgical risks. The goal of therapy for aneurysms is to prevent them from rupturing. Once an abdominal aortic aneurysm has ruptured, the chances of survival are low, with 80 to 90 percent of all ruptured aneurysms resulting in death.
Last week, a 60 year old patient underwent Abdominal Aortic Aneurysm Stenting (Debranching and thoracic abdominal aneurysm stenting) at AHI, in a surgery that was complicated, challenging, SUCCESSFUL.
Case history given by Doctor:
“Patient complained of intermittent abdominal pain and giddiness since 2004, which increased in past few days. The patient is a known case of abdominal aortic aneurysm since 2004.Thoracic and abdominal aortic angiography was done on July 7, 2011, revealing large saccular aneurysm of distal descending thoracic aorta and proximal abdominal aorta stenting at D8 level and extending up to the origin of coeliac artery. The Patient was advised for aortoplasty. Patient is a non-smoker and non alcoholic. He has hypertension since 5 yrs.
The patient suffered from 2 aneurysms, one in the chest and the other in the abdomen. All vital organs in the abdomen such as intestine, kidney, liver were getting the blood supply via the abdominal aneurysm. Hence, stenting it would mean restricting the blood supply to these organs thus proving fatal. Hence, first a new channel was created to supply blood to these organs and then the aneurysm stenting was done. Such a case is very rare and in all likelihood, this surgery WAS THE VERY FIRST OF ITS KIND IN MUMBAI.
