Evaluation of imaging characteristics and clinical application value of multi-slice spiral CT angiography in subarachnoid hemorrhage / 中国医师进修杂志

ABSTRACT

Objective:To evaluate the imaging characteristics and etiology of subarachnoid hemorrhage (SAH) by multi-slice spiral CT angiography (CTA).Methods:A total of 68 SAH patients admitted to Xinchang People′s Hospital from July 2018 to December 2019 were selected as study subjects. CTA and digital subtraction angiography (DSA) were performed on all subjects to compare the detection results of CTA and DSA.Results:Taken DSA results as the "gold standard", this study included 68 SAH patients, including 44 cases of aneurysm detected by DSA correctly, 16 cases of arteriovenous malformation and 8 cases of normal. CTA correctly detected 61 cases, including 45 cases of aneurysms, 16 cases of arteriovenous malformations and 7 cases of normal cases. One case was misdiagnosed as aneurysm, and the diagnosis coincidence rate was 98.53% (67/68). There was no significant difference between CTA and DSA in the detection results of tumor body width and neck width [(6.63 ± 0.75) mm vs. (6.58 ± 0.77) mm, (3.55 ± 0.47) mm vs. (3.49 ± 0.45) mm] ( P > 0.05). Conclusions:CTA has the advantages of non-invasive, rapid and convenient diagnosis of the etiology of SAH, which is conducive to the selection and assessment of clinical surgical treatment.
