Abstract
ObjectiveTo investigate the clinical application value of RAPID software based on computed tomography perfusion imaging (CTP) in the endovascular treatment of acute basilar artery occlusion (BAO). Materials and MethodsThe data of patients with acute basilar artery occlusion who received endovascular treatment in Taizhou Hospital, Zhejiang Province, between January 2020 and April 2021 were retrospectively analysed. The patients were divided into a perfusion imaging and a no-perfusion imaging group based on whether the image analysis results were obtained by RAPID software. Age, preoperative National Institute of Health stroke scale (NIHSS) score, onset to puncture time (OPT), operation methods, good prognosis at 3 months after surgery (modified Rankin scale (mRS) score ≤3), symptomatic intracranial haemorrhage (sICH) and other clinical data were compared between the two groups. Multivariate logistic regression analysis was used to identify the independent factors affecting the prognosis of BAO patients. ResultsIn total, 61 patients with acute BAO were included: 31 patients in the perfusion imaging group and 30 patients in the no-perfusion imaging group. There were no statistically significant differences between the two groups in age, NIHSS score or operation methods (all P >0.05). However, OPT and the good prognosis rate were significantly higher in the perfusion imaging group than in the no-perfusion imaging group (χ2=8.176, 5.003, P < 0.05). SICH was significantly lower in the perfusion imaging group than in the no-perfusion imaging group (χ2=5.628, P < 0.05). Logistic regression analysis showed that the image analysis results of RAPID software influenced the prognosis of EVT in patients with acute BAO (OR=4.048, 95%CI: 1.276-12.840). ConclusionsRAPID software based on CTP can be used for preoperative screening of patients with acute basilar artery occlusion to identify those suitable for endovascular treatment, which is worthy of clinical promotion.
