目的：探讨将一侧颈外静脉与双侧颈总动脉吻合建立侧壁动脉瘤的可行性。材料与方法：对10只犬应用显微外科技术进行颈外静脉、颈总动脉端侧吻合，作血管造影证实瘤腔存在及载瘤动脉通畅。结果：10只犬均成功地建成颈总动脉侧壁动脉瘤，其中8例为宽颈动脉瘤。结论：应用犬一侧颈外静脉与双侧须总动脉吻合建立双侧颈总动脉动脉瘤特别是宽颈动脉瘤切实可行。
Objective: To explore the feasibility of establishing an aneurysm of lateral wall by anastomosing one external jugular vein with bilateral common carotid artery. Materials and Methods: Ten dogs were treated with microsurgical technique for external jugular and common carotid artery anastomosis. Angiography was performed to confirm the existence of tumor cavity and the patency of the parent artery. Results: Ten dogs were successfully established carotid artery aneurysms, of which 8 cases were wide-necked aneurysms. Conclusion: It is practicable to establish bilateral common carotid artery aneurysms, especially wide-necked aneurysms, by using an anternal canine external jugular vein and bilateral aortic common anastomosis.
