Abstract:
A 51-year-old man was referred to our institution for patent ductus arteriosus (PDA) complicated by left ventricular dysfunction and pulmonary hypertension. Surgical closure of a PDA is usually carried out via a small posterior thoracotomy. However, thoracoscopic procedures are probably not appropriate in adults because of the frequency of calcification and the greater risk of rupture while ligating the ductus. To minimize surgical trauma, we used hybrid endovascular stent grafting combined with revascularization of the left subclavian artery, which enabled us to eliminate shunt flow to the pulmonary artery. At 11-month follow-up, the patient was asymptomatic and showed no complications.
