Abdominal aortic aneurysm--a plea for early elective excision (aneurysmectomy).
Though peripheral arterial disease is not as common as in the Western countries, abdominal aorit aneurysm (AAA) is the most frequent arterial problem in Malaysia. A prospective study was made of 100 consecutive patients who presented with AAA to the author between January 1986 to September 1988 (31 months' period). There were 88 males and 12 females. The age range was 47-90 years, mean = 68.7. All the major ethnic rates were equally affected. The sizes of the AAA were documented by ultrasonography and the diameters ranged from 3-10 centimetres, mean = 5.8. Aneurysmectomy was performed on 58 patients, 17 of which were emergencies for ruptured AAA. The operative mortality for elective surgery was 2 percent, but that for emergency surgery was 47 percent. Ten patients refused surgery and 28 were not offered an operation. The true incidence of AAA is likely to be much higher than the number of patients referred for treatment. Many cases are not diagnosed or referred for treatment. Many cases of ruptured AAA died at home or in peripheral hospitals without a diagnosis being made. It is estimated that an AAA is present in 17,000 persons in Peninsular Malaysia. The risk of elective surgery is significantly lower than that of emergency. The overall mortality for ruptured AAA is even higher at about 99 percent. Furthermore, AAA is a benign disease and after surgery the patients return to their normal life expectancy. It is recommended that patients with AAA of five centimetres or more should be advised surgery if premature death is to be avoided.
