Résumé
Abstract Paroxysmal nocturnal hemoglobinuria (PNH) is an ultra-orphan disease. We report the first case in the literature of Off-Pump Coronary Revascularization Using Bilateral Internal Thoracic Arteries in a patient with paroxysmal nocturnal hemoglobinuria. A 36-year-old man came to the emergency department with acute non-ST elevation myocardial infarction (NSTEMI). He presented paroxysmal nocturnal hemoglobinuria diagnosed in 2016. Coronary angiography revealed tripple vessel disease. The conduits used for coronary revascularization were both internal thoracic arteries (left ITA-right ITA [LITA-RITA]). We consider that off-pump coronary artery bypass grafting (OPCABG) using Bilateral Internal Thoracic Arteries (BITA) can be safely performed with low in-hospital mortality and complications rates, even in patient with PNH.

PURPOSE: Bilateral in situ internal thoracic artery (ITA) bypassing may result in excellent myocardial revascularization without increasing the risk of deep sternal wound infection. Although there have been concerns with the use of pedicled bilateral ITA, the risk of infection may not be greater than the use of skeletonized ITA. MATERIALS AND METHODS: The present study was retrospectively undertaken to determine if pedicled BITA grafts are associated with a higher risk of sternal wound complications. A total of 207 patients who underwent bilateral ITA bypasses with or without existing diabetes mellitus, and 162 patients of those received bilateral pedicled ITA and 98 patients received unilateral ITA bypass grafts. RESULTS: No sternal wound complications were noted in either the bilateral ITA or unilateral left ITA groups. CONCLUSION: Bilateral pedicled ITA harvesting was not associated with a greater incidence of infectious sternal complications compared to patients receiving unilateral ITA bypass grafts.

PURPOSE: To analyze the late results of patients who underwent left coronary myocardial revascularization with both internal thoracic arteries, with the right internal thoracic through the transverse sinus. METHODS: From July/83 to September/96, 233 patients underwent myocardial revascularization, with ages ranging from 35 to 76 (average of 52.8) years. One hundred and eighty five were male and 48 female. Internal thoracic arteries (466), saphenous veins (192) and epigastric arteries (11) were employed. RESULTS: The hospital mortality was 3and the late mortality was 6.1. The immediate postoperative bleeding was 0.8, mediastinitis 1.7and myocardial infarction 2.1. The immediate and late coronariography showed the rates of patency, respectively: left internal thoracic artery 98and 96, right internal thoracic artery 96and 92, and saphenous vein grafts 80and 67.5. CONCLUSION: The main advantage in using both internal thoracic arteries in the revascularization of the left coronary branches was the better quality of life, the low rates of cardiac events and the absence of reoperation due to occlusion of the grafts.
