The paper describes a double symmetrical aortic arch in a dog trapping the oesophagus. Thoracotomy was performed in the fourth inter-costal space under general, isoflurane-maintained, anaesthesia. Cutting of the arterial ligament failed to free the oesophagus. Dissection of further vascular structures revealed the left and right aortic arches to be of similar diameter. A vascular clamp was put ...
A 36-year-old male patient with no remarkable medical history was admitted to our hospital for a health check up. On chest radiography, bilateral aortic notches at the level of aortic arch were shown suggesting aortic arch anomaly without any clinical symptoms. Two aortic arches were almost same-in-size on suprasternal view of transthoracic echocardiography. In addition, multidetector computed ...
OBJECTIVE Thoracic, arch, and proximal descending thoracic aorta diseases are still considered an enormous challenge. The hybrid approach developed in recent years (supra-aortic trunks debranching and thoracic endovascular repair aortic repair; TEVAR) may improve the morbidity and mortality of the population at risk. The aim of this study was to analyze retrospectively our experience in the hyb...
Thoracic endovascular aortic reconstruction (TEVAR) is increasingly used in the management of descending aortic pathology including aneurysms, dissections and transaction. When treating aortic arch pathology, hybrid procedures have been devised, in which major supra-aortic arteries are translocated using a variety of techniques. Such hybrid procedures offer an attractive alternative to open arc...
OBJECTIVE The aim of our study was to analyse experience with repair of truncus arteriosus with interrupted aortic arch. METHODS Between 1993 and 2004, eight consecutive patients underwent repair of truncus arteriosus with interrupted aortic arch. The median age was 6.5 days (range 1-85 days) and median weight was 3.2 kg (range 2.6-4.8 kg). Five patients had type A and 3 patients had type B a...
Progressive dilatation of the false lumen in the arch and descending aorta has been encountered in one-third of survivors as a late sequelae following repair of ascending aortic dissection. Conventional treatment for the same requiring cardiopulmonary bypass and deep hypothermic circulatory arrest is associated with high morbidity and mortality especially in the elderly cohort of patients. Here...
OBJECTIVE A number of factors limit the effectiveness of current aortic arch studies in assessing optimal neuroprotection strategies, including insufficient patient numbers, heterogenous definitions of clinical variables, multiple technical strategies, inadequate reporting of surgical outcomes and a lack of collaborative effort. We have formed an international coalition of centres to provide mo...
Knowledge of the branching pattern of aortic arch is important during supra-aortic angiography, aortic instrumentation, thoracic and neck surgery. The purpose of this study is to describe different branching pattern of arch of aorta in Indian subjects, in order to offer useful data to anatomists, radiologists, vascular surgeons while relating it to the embryological basis. Seventy five arches o...
OBJECTIVES To elucidate the role of fluid mechanical factors in the localized genesis and development of atherosclerotic lesions in man. METHODS Flow patterns and preferred sites of atherosclerotic lesions in the human aortic arch were studied in detail using isolated transparent aortic trees prepared from humans postmortem and by means of flow visualization of tracer polystyrene microspheres...
