目的:为临床结扎或切除一侧横窦或乙状窦及颈内静脉提供依据。材料与方法:对104例窦汇区造影片进行回顾性研究,用双侧颈动脉或加椎动脉造影的方法确定窦汇区分流类型。结果:窦汇区分流可分为5种类型:(1)主要右侧分流占54.8%;(2)对称分流29.8%;(3)主要左侧10.6%;(4)单一右侧3.9%;(5)单一左侧0.9%。发现2例有临床意义的分流变异。左、右横窦在窦汇直接相通者占30.77%。结论:在临床上凡涉及结扎一侧静脉窦的患者,均应术前判明窦汇区分流类型和侧支循环。
Objective: To provide a basis for clinical ligation or resection of transverse sinus or sigmoid sinus and internal jugular vein. Materials and Methods: A retrospective study was performed on 104 cases of Douhui District film. The type of the diversion of the Douhui area was determined by bilateral carotid artery or vertebral artery angiography. Results: There were 5 types of diversion in Douhui area: (1) 54.8% of main right shunt; (2) 29.8% of symmetrical shunt; (3) main left 10.6%; (4) single right 3.9% (5) Single left 0.9%. Two clinically significant shunt variations were found. Left and right transverse sinus in direct contact with sinus exchange accounted for 30.77%. Conclusion: All patients involved in the ligation of the sinuses on one side of the ventricle should be identified preoperatively in terms of the type of bypass and the collateral circulation.
