[Morphology of abdominal aortic aneurysm and its clinical importance]
1Department of Surgery, First Teaching Hospital, China Medical University, Shenyang 110001, China.
Objective:
To investigate the morphology of abdominal aortic aneurysms(AAA) and anatomical importance in endovascular surgery.
Methods:
The images of AAA were measured by spiral CT angiography in 30 patients from January 1998 to December 2000.
Results:
The mean diameter of AAA was 5.9 cm (range: 4.0-12.2). The diameter of AAA was positively correlated with neck angle (r = 0.47, P < 0.05) and negatively correlated with neck length(r = -0.41, P < 0.05). Twelve patients(40%) were anatomically feasible for endovascular repair (EVR); 18 patients were excluded for EVR due to angulated proximal necks (mean 88.8 degrees, range 70 degrees-110 degrees) (16 patients; 53.3%), short neck (1; 3.3%), and unilateral common iliac artery occlusion with thrombosis in neck (1; 3.3%).
Conclusion:
The angulated neck was a major single factor for excluding Chinese patients from EVR.
