Accidental subclavian artery cannulation is an uncommon but potentially serious complication of central venous catheterization. Removal of a catheter inadvertently placed in the subclavian artery can lead to substantial bleeding, as achieving hemostasis in this area through manual compression presents considerable difficulty. Additionally, surgical treatment might be unsuitable for high-risk pa...

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 ...

The subclavian steal syndrome is a well-recognized clinical and radiographic entity that involves the left subclavian artery far more commonly than the right. Atherosclerotic stenoses are the most common underlying cause [1-3]. Right subclavian stenosis with associated steal is markedly less common. Although an aberrant right subclavian artery is one of the most common anomalies of the great ve...

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...

We present a 55-year-old man with repeated transient symptoms of vertebrobasilar arterial pathology. Physical examination detected no signs that would indicate the stenosis of the proximal subclavian artery segment. Ultrasound detected hemodynamic disorder of right vertebral artery, which correspond to a partial subclavian steal syndrome. Angiography shows fusiform aneurysm of ipsilateral subcl...

BACKGROUND Subclavian artery dissection is a rare entity. It is usually associated with anomalous aortic vasculature. Only with trauma or catheterization procedures is subclavian artery dissection with normal aortic vasculature reported. PATIENT We describe a patient with intrascapular pain, an occipital headache, and 3 distinct infarctions in the nervous system. He had spontaneous subclavian...

Continuous-wave Doppler sonography is a reliable method for detecting severe subclavian stenosis and occlusion as well as subclavian steal. Intermediate stages leading to subclavian steal can also be detected. These are characterized by a cardiac-phase-dependent alternating flow direction in the vertebral artery. Some cases of proximal subclavian or proximal vertebral artery stenosis produce a ...

INTRODUCTION Surgical treatment of symptomatic occlusive lesions of the proximal subclavian artery is infrequently necessary. Carotid subclavian bypass has gained popularity and is now considered standard treatment when stenting is not possible. Exposure of the subclavian artery and bypass grafting onto it is difficult, as the vessel is delicate, thin-walled and located deep in the supraclavicu...

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...
