Abstract:
Objective To investigate the clinical application value of contrast-enhanced chest CT in the detection of responsible vessels for hemoptysis before selective arterial embolization(SAE).Methods The clinical data of 74 patients with hemoptysis trea-ted with interventional therapy and preoperative contrast-enhanced chest CT and digital subtraction angiography(DSA)were ana-lyzed retrospectively.The responsible vessels were identified and then embolized via angiography.The detection of the responsible vessels via preoperative contrast-enhanced chest CT was analyzed.The patients were followed up to observe the efficacy and compli-cations,and the influencing factors of interventional efficacy and recurrence were analyzed.Results A total of 245 responsible ves-sels were detected by preoperative contrast-enhanced chest CT,including bronchial arteries(n=178),ectopic bronchial arteries(n=10)and non-bronchial systemic artery(NBSA)(n=57),which could accurately show the anatomical information of responsible vessels.A total of 4 posterior intercostal arteries were missed.The diagnostic accuracy was 98.4％(245/249).All patients were followed up for 12 to 25.6 months.The immediate hemostasis rate was 93.2％(69/74)and the effective rate was 79.7％(59/74),respectively.The factors affecting the efficacy were bronchial artery to pulmonary circulation fistula,pleural thickening at the bleeding site,and underly-ing lung disease.Among the 59 patients with effective treatment,underlying lung disease was the influencing factor for postoperative recurrence.Conclusion Contrast-enhanced chest CT can provide anatomical information about the responsible vessels for interven-tional therapy of hemoptysis,improving surgical efficiency and reducing the recurrence rate of hemoptysis.
