상지혈류를 보전한 쇄골하동맥피판 대동맥성형술

Repair of the Coarctation of the Aorta Using the Subclavian Artery as a Flap and Preservation of Arterial Blood Flow to the Left Arm

From April 1990 through June 1990, three patients underwent subclavian flap aortoplasty for relief of the coarctation of the aorta. The age of the patients were 13 days, 7 months and 39 months and their weights were 3.3kg, 6.5kg, and 11kg, respectively. Two patients had persistence of the ductus arteriosus and all patients had associated intracardiac anomalies. We used the technique devised by Mendonca, namely, repair of the coarctation of the aorta using the subclavian artery as a flap and preservation of the arterial blood flow to the left arm. In one patient with long narrowing of isthmus, significant residual pressure gradient was remained by this technique and we added patch aortoplasty. There were no hospital deaths and follow-up over a one year period shows all patients in good condition.
