Aortic Root Reconstruction Using Partial Remodeling Technique for Stanford Type A Acute Aortic Dissection：Report of a Case

はじめに　Stanford A型急性大動脈解離において，基部再建術を要する割合は17～35％とされている1，2）．われわれは，大動脈基部に解離が及んだStanford A型急性大動脈解離例に対して，部分リモデリング（PR）法による自己弁温存基部再建術と上行大動脈人工血管置換術を施行し，良好な結果を得たので報告する．

We report a case of Stanford type A acute aortic dissection successfully treated with partial remodeling （PR） technique for aortic root reconstruction. A 60-year-old male presented with chest pain and was diagnosed as having acute aortic dissection with pericardial effusion. Emergency surgery revealed intimal tear in the right coronary sinus. We performed PR technique, reconstructing only the right coronary sinus with a prosthetic patch while preserving the native aortic valve. The patient recovered well and postoperative computed tomography （CT） showed patent reconstructed right coronary artery. PR technique, when appropriately indicated, offers advantages of shorter operative time with native valve preservation, making it a valuable option for selected cases of acute aortic dissection involving the aortic root.
