Abstract: To evaluate the value of CT angiography (CTA) before interventional embolization in patients with acute complex massive hemoptysis, CTA imaging data of 49 patients with acute complex massive hemoptysis were selected retrospectively. Compared with intraoperative digital subtraction 109 angiography (DSA), it was found that the accuracy rate of vascular diagnosis for criminals was 89.33%,and 86.96% for multi-artery anastomosis. The results of CTA and DSA by Kappa test were in good agreement. Receiver operating characteristic curve (ROC) analysis showed that the area under curve (AUC) of CTA in the diagnosis of acute complicated massive hemorrhage criminals was 0.947 (95%CI:0.903~0.990, P=0.000),with sensitivity 89.33% and specificity 100.00%. Follow-up showed that the effective rate of interventional embolization guided by CTA was 91.84%. There was no recurrence of massive hemoptysis in one year after operation.

Key words: CTA, massive hemoptysis, criminal vessels, interventional embolization
