Cerebral circulation characteristics of patients with persistent trigeminal artery combined with cerebrovascular diseases and their clinical relevance

Abstract

Objective To explore the cerebral circulation characteristics of patients with persistent trigeminal artery (PTA) combined with cerebrovascular diseases and their clinical relevance.Methods Eight patients with PTA,admitted our hospital from March 2010 to March 2013 and conformed by DSA,MR radiography (MRA) or CT angiography (CTA),were chosen in our study; their cerebral circulation features and clinical manifestations were retrospectively analyzed.Results In these eight patients,two were combined with cerebral infarction,one with cerebral artery stenosis,two with cerebral infarction and cerebral artery stenosis,one with transient ischemic attack,and the left two with cerebral aneurysm.Four patients complained for paroxysmal dizziness (one of them with one-side weakness),two patients complained for numbness of a limb,One patient had headache and blepharoptosis and one patient had diplopia.Saltzman type Ⅰ was noted in six patients,type H in one and special type in one.The pathogenesis of cerebral infarction was related to PTA.Conclusion The clinical features of the patients with PTA often determine by merger cerebrovascular diseases; PTA can change the normal cerebral circulation; PTA detection can be helpful in the diagnosis of the pathogenesis of multiple cerebral infarction.
