Dissecting aneurysm is the condition produced by separation of the layers of the arterial wall by circulating blood. Although rare, the coexistence of aortic dissection and aberrant right subclavian artery may be catastrophic. In this study we report the endovascular treatment of a patient with thoracic aorta dissection associated with aberrant right subclavian artery. Aortic clamping proximal ...

Right aortic arch with isolation of the left subclavian artery is a rare anomaly. The incidence of bilateral ductus arteriosus is sporadic, and a right aortic arch with isolation of the left subclavian artery in association with bilateral ductus arteriosus is therefore extremely rare. Since the symptoms and signs of isolation of the left subclavian artery can include the absence or underdevelop...

Figure 1: CT image shows the thoracic aorta and supra-aortic trunks seen from anterior (a) and left (b) point of view. The CT measurements are 16 mm for the ascending aorta and 5 mm for the aortic arch and descending thoracic aorta. AA: ascending aorta; AoA: aortic arch; IA: innominate artery; LSA: left subclavian artery; LVA: left vertebral artery; RSA: right subclavian artery. Figure 2: MRI s...

Cervical origin of the right subclavian artery is rare and is associated with DiGeorge syndrome. During total thyroidectomy and right lateral neck dissection for metastatic thyroid cancer in a 26-year-old female, the right subclavian artery was found to be cervical in origin. This was identifiable on preoperative computerized tomography. Screening for DiGeorge syndrome and other cardiovascular ...

Vertebral artery is the first branch of subclavian artery. It merges with the same artery of the opposite side to form basilar artery and becomes one of the important source of blood supply to the brain. Variation in the origin of left vertebral artery was found in 65 year old female during magnetic resonance angiography of the neck vessels. It originated from aortic arch and was longer as ...
