Objective:To explore the relationship between fetal origin of the posterior cerebral artery (FTP) and cerebral white
matter lesion.Methods:A total of 485 hospitalized patients were recruited in our hospital from 2014 January to 2015 June. All patients
underwent brain magnetic resonance imaging scan and angiography. Cerebral white matter lesion, acute cerebral infarction and FTP were
observed. All patients were randomly divided into observation group with white matter lesion and control group without white matter lesion.
The incidence of FTP was compared.Results:The observation group and control group included 232 and 253 cases, respectively.
Fifty-three patients with FTP were detected in observation group (15 cases, 19 cases, 19 cases with left, right and bilateral FTP, respectively).
The incidence of total FTP was 22.8 %. The incidence of left, right and bilateral FTP was 6.5 %, 8.2%and 8.2 %, respectively. In
contrast, there were 98 FTP patients in control group (26 cases, 44 cases, 28 cases with left, right and bilateral FTP, respectively). The incidence
of total FTP was 38.7 %. The incidence of left, right and bilateral FTP was 10.3 %, 17.4 % and 11.1 %, respectively. The incidence
of total and right FTP in observation group was much lower than that in control group (P<0.001 and P<0.01). In our results, there
were 156 and 76 cases with and without acute cerebral infarction, respectively, in observation group with 232 patients. Twenty-eight FTP
cases were found in patients with cerebral infarction (7 cases, 15 cases, 6 cases with left, right and bilateral FTP, respectively). The incidence
of total, left, right and bilateral FTP was 17.9 %, 4.5 %, 9.6 %and 3.8 %, respectively. There were 24 FTP cases without cerebral
infarction (8 cases, 4 cases, 12 cases with left, right and bilateral FTP, respectively). The incidence of total, left, right and bilateral FTP
was 31.6 %, 10.5 %, 5.3 % and 15.8 %. There was significant reduction in the incidence of total and bilateral FTP in observation group
compared with control group (P<0.05 and P<0.01).Conclusion:FTP might reduce the occurrence of white matter lesion and even cerebral
infarction. |
