One Hundred and One Open Abdominal Aortic Aneurysm Repairs: 5 Years’ Experience at Lampang Regional Hospital, Thailand
Keywords:
Abdominal aortic aneurysm, open abdominal aortic aneurysm repairAbstract
Objective: To delineate the natural presentation of abdominal aortic aneurysm (AAA) patients in LampangRegional hospital and audit the results of open AAA repair performed by one surgeon over a 5-year period.
Methods: A survey of 101 consecutive AAA patients during August 2005 and August 2010 was performed.
Outcomes included hospital death, major complication, co-morbidity and causes of death after AAA repair.
Results: Among the 101 AAA patients, 66 (65%) underwent elective repair. Nine (9%) cases had ruptured AAA
(1 case of free rupture, 8 cases of contained rupture). Twenty-six (26%) patients underwent urgent repair for the
symptomatic AAA, including 7 (27%) with distal embolization causing limb and toe gangrene that required further
amputation, 5 (19%) with aortoenteric fistula, 1 (3%) with thrombosed AAA, 6 (23%) with inflammatory AAA, 5 (19%)
with infected AAA, 2 (7%) with infected previous aortic graft, and 3 (11.5%) with painful AAA of unknown cause.
The 30-day hospital deaths included 2 patients (3%) in the elective group, 1 (100%) with free rupture, 2 (25%) with
contained rupture and 3 (12%) in the urgent group. Major causes of death in 8 patients included 4 (50%) from
ischemic heart disease, 2 (25%) from acute renal failure and 2 (25%) from respiratory failure due to chronic
obstructive pulmonary disease (COPD).
Conclusions: The most significant comorbidity and cause of death of patients after AAA repair included
ischemic heart diseases, renal failure and COPD.
