Analysis of Venous Drainage Patterns and DSA Cerebral Circulation Time in 44 Cases of Lacunar Infaction
Abstract：Objective To investigate the characteristics of venous drainage patterns and its relationship with cerebral circulation time in lacunar infaction.Methods Digital subtraction angiography ( DSA) were performed in 44 non-acute cases of lacunar infaction , and venous drainage patterns were observed and cerebral circulation time (CCT) was assessed.Results Of the 44 cases,the number of patterns with I type,Ⅱtype and Ⅲtype venous drainage patterns was respectively 8(18.18%),10(22.73%)and 26(59.09%).The patients with ⅢtypevenousdrainagepatternshowedlongerCCTthanthoseofItypeandⅡtypevenousdrainagepatterns.Conclusion Ⅲtypevenous drainage pattern may affect the changes of cerebral hemodynamics ,which may be one of risk factors of cerebral infaretion.
