Diagnosis of coronary artery fistulas by multidetector computed tomography
Main Article Content
Abstract
Objective: Evaluate the characteristics of coronary artery fistulas (CAFs) by multidetector computed tomography (MDCT).
Material and methods: During 21 months (between January 2019 and September 2020), study on 31 patients were diagnosed with CAFs on MDCT at Radiology Centre of Bach Mai hospital, prospective descriptive study.
Result: We enrolled 31 patients (11 male, 20 female, mean age 56 years) with CAFs on MDCT. 18 patients had multiple fistulas (58,1%), 13 patients had single communication (41,9%). 6,5% originated from the right coronary, 35,5% arose from the left coronary artery system and 58,5% from both right and left coronary artery. 87,1% of fistulas drain to the right side of the circulation(74,2% drain to pulmonary artery). 1 patient (3,2%) had fistula drain to the left side of the circulation (bronchial artery). 3 patients (9,7%) had fistulas drain to both right and left side of the circulation (pulmonary artery and bronchial artery).
10 patients had large fistulas (32,3%), 21 patients had small fistulas (67,7%). 19 patients had aneurysm of fistulas (61,3%), most of them drain to pulmonary artery (73,7%). 38,7% of patients were diagnosed with CAFs by echocardiography (38,7%). 6 patients were examined by DSA: 2 patients were not detected origin of fistulas by DSA, 3 patients were not detected drainage of fistulas by DSA.
Conclusion: DSCT is a noninvasive and useful modality for diagnosis of CAFs
