Rupture in small abdominal aortic aneurysms

摘要: Abstract Background: The decision of whether to repair small abdominal aortic aneurysms (AAAs), which are those that less than 5 cm in diameter, remains controversial. Methods: We describe 161 consecutive patients who were seen at a single urban hospital with ruptured AAAs (rAAAs) and whom aneurysm size was measured ultrasound scanning, or rarely computed tomography, en route the operating room. Eleven (6.8%) had 5.0 cm. This group compared 150 rAAAs more Results: mortality rates similar both groups—70% for versus 66% large rAAAs. No significant differences between respect prevalence hypertension (60% vs 50%) cardiac disease (20% 22%). However, rate obstructive lung significantly different (64% 25%; P = .02) as diabetes (28% 3%; .004). Five exactly suggests approximately 10% all rupture this series do so less. Conclusion: In view safety elective prohibitive risk associated rupture, good AAA (between 4 cm) should be considered resection. For unclear reasons, greater AAA. Patients these factors given special consideration. (J Vasc Surg 1998;28:884-8.)
