Radial Arteriovenous Fistula after Coronary Angiography = Radial Arteriovenous Fistula after Coronary Angiography

다국어 초록 (Multilingual Abstract)

Introduction: Transradial approach for Coronary angiography has become an increasingly popular technique since it was first introduced in 1989. Because of fewer vascular access complications and a shorter length of hospital stay, use of transradial approachis getting more popularity. We report an extremely rare case of delayed radial arteriovenous fistula formation, 3 months after transradial coronary angiography, which was treated successfully with surgical repair. Case report: A 67-year-old man presented chest pain. He underwent diagnostic coronary angiography via right radial artery, and it was found that he didn’t have coronary artery atherosclerosis. He was discharged one day after the procedure. About 3 months after the day of the diagnostic coronary angiography, he complained of a swishing sensation on the right wrist at the outpatient clinic. An upper extremity angiography revealed arteriovenous fistula between the right radial artery and the adjacent cephalic vein around the right wrist. He was referred to a vascular surgeon and received surgical ligation of the arteriovenous fistula. Discussions: Arteriovenous fistula after transradial approch is an extremely rare complication because of the absence of large veins near the radial artery. Since first noticed in 2005, a few cases were demonstrated to have arteriovenous fistula formation after transradial approch. In this case, upper extremity angiography was performed for diagnosis of AVF formation and surgical repair was done without any complication.
