Aneurysmal disease involving the origins of supra aortic vessels often requires complex open and/or endovascular repair that is not only associated with significant risk of mortality and morbidity but also often with perioperative blood loss requiring transfusion. We report a successful repair of a large thoracic aortic aneurysm (TAA) involving the aortic arch with a custom-made Bolton Relay 2-vessel branched thoracic aortic endograft in a 42-year-old Jehovah's Witness who would otherwise be very unlikely to survive an open repair...

A double left brachiocephalic vein is an uncommon anatomic variation. Among these, a accessory branch with preaortic course is extremely rare. In this case, both branches of the left brachiocephalic vein were anterior to the aortic arch. We describe the computed tomography findings with volume-rendering imaging of this rare anatomic variation.

OBJECTIVES: Endovascular repair of aortic arch pathologies remains challenging. Recently, needle based in situ fenestration (ISF) has shown great potential in endovascular total aortic arch repair (ETAAR). This study aimed to evaluate the feasibility, effectiveness, and safety of ETAAR via needle based ISF, and to present initial experience with this technique. DESIGN AND METHODS: Patients who met the inclusion criteria were enrolled in this prospective study. The supra-arch branches were manually punctured in a retrograde manner using liver biopsy needles (18 gauge/30 cm) in the left common carotid artery (LCCA) and brachiocephalic trunk (BCT), and endo-puncture system or aspiration biopsy needles (21-gauge) in the left subclavian artery (LSA)...

AIM: The aim of this study is to investigate the incidence of variation in the branching pattern of aortic arch (AA) vessels in an Irish population. METHOD: A cadaveric study of 24 subjects was conducted. The vessels of the AA were identified, their branching patterns were noted and photographed and the following measurements were recorded: the angle of the AA to the coronal plane, the distance from the midline to the brachiocephalic trunk (BCT); the left common carotid artery (LCC) ; the left subclavian artery (LSC), the distance between the BCT and the right subclavian artery (RSC); the RSC and the right vertebral artery (RVA), and between the LSC and left vertebral artery (LVA)...

A 16-year-old boy who was a non-smoker presented with a prolonged severe dry cough and malaise of 3 months in duration. Despite an increase in the patient's inflammatory marker levels, no respiratory lesions were radiologically or serologically detected. We suspected that the cough reflex pathway had been stimulated by large vessel vasculitis (a non-respiratory inflammatory condition) and diagnosed the patient with Takayasu arteritis. While inflammation of either the ascending pharyngeal or pulmonary artery have been reported to cause cough in patients with large vessel vasculitis, the present case shows that intense inflammation of the aortic arch and the starting portion of its main branches may stimulate a vagus nerve branch as a novel mechanism causing cough...

PURPOSE: Thoracic endovascular aortic repair (TEVAR) is the preferred treatment of descending thoracic aorta pathology. However, TEVAR in the aortic arch remains challenging. Customized fenestrated TEVAR (fTEVAR) allows extension of the proximal seal zone, while preserving the involved supra-aortic vessels. There is a paucity of information on fTEVAR; hence, we aim to evaluate our early experience and lessons learnt with fTEVAR in the aortic arch. METHODS: This is a retrospective single-centre review of fTEVAR endografts for aortic arch pathology over 24 months...

The available information about anatomical characteristics of the cardiovascular system of the alpaca (Vicugna pacos, Linnaeus 1758) is scarce. The general objective of this work was to describe its heart anatomy. We dissected six adult animals and five neonates. The heart of the alpaca was located in the middle mediastinum, with a craniocaudal extension from the third to the sixth rib. No ligament that connected the fibrous pericardium to the sternum or to the diaphragm was detected. In the right atrium, there was a developed crista terminalis and small pectinate muscles...

Patent ductus arteriosus (PDA) stenting has gained acceptance for palliation in cyanotic congenital heart disease. The PDA in tetralogy of Fallot with pulmonary atresia (ToF-PA) arises, in the left aortic arch, from underneath the arch and connects to the proximal left pulmonary artery, often resulting in stenosis. The PDA is usually elongated and tortuous, making stent implantation challenging. Shorter duration of palliation, aggravation of branch pulmonary artery stenosis resulting in poor growth and difficulty at surgery makes ductal stenting controversial...

This study examined the branching pattern of the aortic arch (AA) and its major branches in the Siberian roe deer (Capreolus pygargus Pallas, 1771) from South Korea. A total of eight of the nine expected types, based on the branching site and bilateral levels of the costocervical trunk (CCT) and subclavian artery (SB), were observed in the arterial silicone casts of 35 deer (16 males, 19 females). This deer has no typical type. The three most common types were present in 28.6%, 25.7%, and 20.0% of cases and resulted from different branching patterns of the left CCT and left SB...

OBJECTIVES: Arch branching has never been shown to influence recoarctation after extended end-to-end anastomosis via thoracotomy, yet in each study bovine arch identification is grossly underreported. This study aims to (1) assess chart review reliability in bovine arch identification; (2) determine recoarctation risk with a bovine arch; and (3) explore an anatomic explanation for recurrent arch obstruction based on arch anatomy. PATIENTS: A total of 49 consecutive patients underwent thoracotomy with extended end-to-end aortic coarctation repair at a single institution (2007-2012)...

A novel custom-made E-Vita Open prosthesis (JOTEC GmbH, Hechingen, Germany) has been designed with 2 additional side branches. The first one, the reperfusion branch, allows distal aortic perfusion after the collar anastomosis of a frozen elephant trunk repair has been performed. The second one, the debranching branch, permits reimplantation of any configuration of supraaortic debranching to the dacron graft. This modified graft provides two main advantages: first, combined with prior carotid-subclavian bypass and bilateral axillary perfusion, it allows continuous bihemispheric antegrade perfusion and arch-first technique under mild hypothermia (32°C); second, it grants distal aortic reperfusion after distal anastomosis completion performed under moderate hypothermia (28°C)...

The reattachment of the supra-aortic vessels during hybrid arch repair using a branched prosthesis is time consuming and sometimes technically challenging. Here, we describe the surgical technique of bridging the end-to-end anastomoses between the graft branches and the supra-aortic vessels by self-expanding covered stents to reduce suturing time, avoid anastomotic bleeding, enhance true lumen remodeling, and improve vessel alignment to the hybrid graft.

PURPOSE: Cardiovascular diseases remain the number one death cause worldwide. Preclinical 4D flow phase contrast magnetic resonance imaging can provide substantial insights in the analysis of aortic pathophysiologies in various animal models. These insights may allow a better understanding of pathophysiologies, therapy monitoring, and can possibly be translated to humans. This study provides a framework to acquire the velocity field within the aortic arch. It analyses important flow values at different locations within the aortic arch...

Here, we present a unique case with 5 branches of the aortic arch (AA), namely the right common carotid artery, left common carotid artery, left thyrocervical trunk, left subclavian artery and right subclavian artery (RSA), from right to left. We found that the left thyrocervical trunk originated directly from the AA rather than the left subclavian artery. In addition, the RSA arose dorsally as the last branch of the AA and passed posteriorly to the oesophagus to supply the right upper limb. In addition, the right vertebral artery originated from the right common carotid artery instead of the RSA...
