The presence of malperfusion syndrome in cases of complicated acute type B aortic dissection is a negative predictive factor and urgent intervention is indicated. Anatomic variations, such as the Arc of Buhler, contribute anastomotic channels and can preserve the visceral blood supply. In this case report, we describe the overall management of a 54-year-old man who presented with a type B aortic dissection. Initially, conservative management was chosen, as indicated for an uncomplicated type B dissection, but the dissection deteriorated. Despite the fact that severe occlusion of the celiac artery was detected on Computed Tomography (CT) angiography, the Arc of Buhler anatomical variation was present, contributing adequate visceral blood supply. After considering this finding, the patient was treated effectively with thoracic endovascular aortic repair (TEVAR).

Disseminated intravascular coagulopathy (DIC) is a very rare outcome post endovascular repair of aortic aneurysm dissections. We present a case of a 70-year-old male who presented with DIC post a thoracic endovascular aortic repair (TEVAR) procedure due to a type 1A endoleak. Initially, the patient was treated with red blood cells and blood products; however, when failing to improve, he underwent a hybrid arch replacement. In this study, we will analyze the management of DIC post TEVAR and look at its presentation more extensively, as it is currently a topic that is poorly studied.

Ligation of the left innominate vein (LIV) expands the surgeon’s surgical field for ascending aorta and aortic arch procedures. Although it is considered a safe technique by most surgeons in that it is associated with only minor drawbacks, conflicting views exist regarding this method. We herein describe a 70-year-old woman who underwent ascending aorta replacement due to an aneurysm with subsequent cerebral dysfunction caused by extended brain edema, possibly related to LIV ligation, leading to her death.
