【摘要】 目的　了解腹主动脉瘤的形态学特点对腔内修复术 (EVR)治疗方法的影响。　方法应用螺旋CT血管造影检测了 30例腹主动脉瘤并收集解剖学数据。　结果　动脉瘤平均最大直径5 9cm (4 0～ 12 2cm) ,腹主动脉瘤直径与瘤颈的角度呈正相关 (r=0 47,P <0 0 5 ) ;与瘤颈长度呈负相关 (r =- 0 41,P <0 0 5 )。本组病例中有 12例 (4 0 % )符合EVR要求的解剖条件 ,18例不适合EVR手术 ,其中 16例 (5 3 3% )因瘤颈角度过大 (平均 88 8° ,范围 70°～ 110° ,其中 4例合并髂总动脉瘤 ) ,1例 (3 3% )因瘤颈过短 ,另 1例 (3 3% )单侧髂总动脉闭塞伴瘤颈附壁血栓。　结论　影响腹主动脉瘤EVR手术最主要的单一因素是瘤颈角度过大。这是与欧美腹主动脉瘤病例不同的形态学特点更多还原

【Abstract】 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°, range 70°-110°)(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.更多还原
