Abstract:
Objective:To explore the correlation between subclavian artery stenosis disease (SASD) classification and posterior circulation ischemia.Methods:A retrospective study was performed; the clinical data, and Doppler vascular ultrasound and vascular imaging results of 81 SASD patients, admitted to Cerebrovascular Stenosis Diagnosis and Treatment Center, Second Affiliated Hospital of Qiqihar Medical College and Department of Neurology, Rocket Force Specialty Medical Center from May 2018 to August 2023, were collected. SASD was categorized into 2 types (single type and concurrent type) based on the presence or absence of other posterior circulation artery (basilar artery, vertebral artery, or subclavian artery distal segment) stenosis/occlusion, and into 3 groups (non-posterior circulation ischemia group, posterior circulation transient ischemic attack group and posterior circulation cerebral infarction group) based on the presence or absence of posterior circulation ischemia. Blood stealing pathways in different SASD classifications were analyzed, and correlation of SASD classification with posterior circulation ischemia was discussed.Results:Single-type SASD was noted in 44 patients (54.3%), mainly initiating blood stealing through the vertebral artery to the vertebral artery and then to the subclavian artery ( n=26); concurrent-type SASD was noted in 37 patients (45.7%), mainly initiating blood stealing through the occipital artery to the costocervical trunk and then to the subclavian artery ( n=10). Sixty-five patients (80.2%) were into the non-posterior circulation ischemia group, 4 (4.9%) into the posterior circulation transient ischemic attack group and 12 (14.8%) into the posterior circulation cerebral infarction group. Among the 44 patients with single-type SASD, 39 did not have posterior circulation ischemia, and 3 had posterior circulation cerebral infarction. Among the 37 patients with concurrent-type SASD, 26 did not have posterior circulation ischemia, and 9 had posterior circulation cerebral infarction. Conclusion:Initiation of blood stealing in SASD patients is related to SASD classification, and concurrent-type SASD patients trend to have posterior circulation ischemia.
