BACKGROUND Reconstruction of the aortic major branches during thoracic endovascular aortic repair is complicated because of the complex anatomic configuration and variation of the aortic arch. In situ laser fenestration has shown great potential for the revascularization of aortic branches. This study aims to evaluate the feasibility, effectiveness, and safety of in situ laser fenestration on t...
OBJECTIVES The purpose of this study was to determine the frequency of chromosome 22q11 deletions in patients with isolated anomalies of the aortic arch and its branches. BACKGROUND Chromosome 22q11 deletions are often present in patients with certain forms of congenital cardiovascular disease, including tetralogy of Fallot, truncus arteriosus and interruption of the aortic arch. Among patien...
Background/Introduction Congenital anomalies of the aortic arch gather a wide spectrum of malformations concerning the aortic arch or some of its branches and the pulmonary artery. These malformations are rare (1 in 1000 live births) and sometimes responsible of complete (vascular ring) or partial (vascular sling) encirclement of the oesophagus, trachea or bronchi. In cases of symptomatic airwa...
BACKGROUND Aortic dissection (AD) represents a clinically uncommon aortic pathology which predicts a dismal prognosis if not promptly treated. In acute Debakey type I AD (ADIAD), aortic lesion extends from aortic root to even distal abdominal aorta among which aortic arch and its three main branches still remain a great surgical challenge for repair and reconstruction. Several decades have witn...
This is the first case performed in world of a complete endovascular aortic arch repair using an endograft with three retrograde branches requiring only unilateral femoral artery access. design simplifies steps for by eliminating need supra-aortic exposure and/or demonstrates evolution minimally invasive technologies and represents transformative change approach to aneurysmal disease. eyJraWQiO...
INTRODUCTION Double aortic arch is a congenital vascular abnormality in which the connected segments and their branches course between and compress the trachea and esophagus, often resulting in invariable airway compression. CASE PRESENTATION A 4-year-old boy with a history of recurrent wheezing was admitted to our hospital for evaluation of asthma based on his past medical history, persisten...
INTRODUCTION This study aimed to evaluate the feasibility of total endovascular repair of the aortic arch in pigs using improved integrated double-branched stent grafts. METHODS Improved self-expandable stent grafts with a main body and two integrated branches were prepared for the repair of the aortic arch in six pigs. The feasibility of using these stent grafts was evaluated with arteriogra...
Variations of the branches of the aortic arch are likely to occur as a result of the altered development of certain branchial arch arteries during the embryonic period of gestation. In the present investigation the pattern of branches of the aortic arch was studied in 81 cadavers from a recent South Australian population of European descent, who have migrated to (n = 38) or were born and lived ...
