Resection of redundant segment in ulnar artery kinking with subsequent autologous prosthetic repair
Keywords:
ulnar artery, kinking, autologous prosthesisAbstract
Introduction: Kinking of the distal ulnar artery is a vascular anomaly characterized by abnormal twists or folds in an artery, associated with advanced age, female sex, hypertension, and other cardiovascular factors. It is very rare and its prevalence is less than 1 %. It had not been reported to the service before.
Objective: To present the case of a patient diagnosed with kinking of the distal ulnar artery, with another therapeutic option.
Clinical Case: A 57-year-old Caucasian male from an urban area with a history of hypertension had previously presented with asymptomatic enlargement of the left wrist and symptoms of cramping, numbness, and moderate pain in the hand over the past 6 months, suggesting compression of the ulnar nerve due to a possible aneurysm. Physical examination revealed a pulsatile mass in the wrist (synchronous with the heart rate, without a murmur). Imaging (doppler): tortuosity with multiple kinks in the ulnar artery (kinking), without aneurysm. Final diagnosis: kinking of the ulnar artery. Surgical treatment: resection of the tortuous segment plus autologous cephalic vein graft. Outcome: favorable, with follow-up in the outpatient clinic.
Conclusion: Kinking of the ulnar artery is rare, but should be considered in cases of unexplained pain or digital ischemia. Among the therapeutic options, the use of a cephalic vein as a prosthesis to maintain perfusion is considered (as opposed to traditional ligation).
