摘要
目的：探讨颈内动脉一后交通动脉（ICA-PCoA）动脉瘤形成的形态学因素。方法：收集2000年1月—2005年5月南方医科大学珠江医院收治的ICA-PCoA动脉瘤患者（41例）和非脑动脉瘤对照者（30例）的病历资料。根据脑血管造影片，测量ICA-PCoA动脉瘤患者和对照者颈内动脉C1段、C2段夹角，并对患侧、对侧及对照组进行比较分析。结果：ICA-PCoA动脉瘤患者年龄31～73岁，平均（49．64±12．50）岁，高峰段为40～50岁。男性17例，占41．46％，女性24例，占58．54％。18例（43．9％）有高血压史。3例为多发性动脉瘤，均为两侧各有1个ICA-PCoA动脉瘤。在44个ICA-PCoA动脉瘤中，26个位于右侧，18个位于左侧。ICA-PCoA动脉瘤患侧颈内动脉C1段、C2段平均夹角（90．80±22．87°）显著小于对侧（99．34±19．70°，P=0．002）和对照组（114．33±34．98°，P〈0．001）。结论：ICA-PCoA动脉瘤的形成可能与高血压和颈内动脉C1、C2段转折处夹角大小有关。
Objection.. To investigate the morphological factors of internal carotid-posterior communicating artery （ICA-PCoA） aneurysm formation. Methods： The medical records in patients with ICA-PCoA aneurysm （n = 41 ） and non-aneurysm controls （n =30）, who were admitted to Zhujiang Hospital, Southern Medical University from January 2000 to May 2005, were collected. The angles at C1 and C2 segments were measured in patients with ICA-PCoA and the controls according to their angiograms; and the affected sides, the contralateral sides and the controls were compared and analyzed. Results： The patients with ICA-PCoA ranged in age from 31 to 73 years （mean 49.64 ± 12.50）, and most of them were 40 to 50 years old; 17 patients （41.46%） were male and 24 （58.54%） were female. Eighteen patients （43.9%） had a history of hypertension, Three patients had multiple aneurysms; an ICA-PCoA aneurysm was on both sides. Of the 44 ICA-PCoA aneurysms, 26 were on the right side and 18 were on the left side. The average angle of the affected ICA-PCoA aneurysms at C1 and C2 segments was 90. 80 ± 22. 87°, which was significantly less than that on the contralateral side （99.34 ± 1.70°, P =0. 002） and in the control group （114.33 ±34.98°, P 〈0. 001）. Conclusion.. The formation of ICA-PCoA aneurysms may be associated with hypertension and the size of angle at C1 and C2 segments of the ICA.
