This paper investigates the mechanical properties of blood flow in main arterial system of human. The system includes aorta, subclavian, mesosentric, iliac artery, renal artery, celiac artery. The geometric domain of artery network is obtained using a real patient data. As an input, Womersley velocity profile [2] is used. Combination of thirteen arteries with aorta gives better understanding of...

We report a case of retroesophageal right subclavian artery identified in a 59-year-old Japanese female during routine dissection in Nagasaki University School of Medicine. This kind of variation is relatively rare; however, reports of such cases have accumulated. We paid attention to the intersegmental arteries and above all, the second intercostal artery. On the other hand, there have been re...

Broadly defined, aortopulmonary collateral blood vessels (APCs) arise from the systemic arteries and supply blood to the pulmonary circulation. In the setting of acquired and congenital pulmonary and cardiac disease, the number and caliber of these vessels can increase and lead to a significant systemic-to-pulmonary shunt. APCs typically arise from the descending aorta, subclavian artery branch...

Correspondence To the Editor: Aberrant right subclavian artery (ARSA) is a congenital vascular anomaly. Stanford‑type A aortic dissection with ARSA is rare. We reported a strategy that involved the use of a four‑branch prosthetic graft to reconstruct the four supra‑arch branch vessels for a Stanford type A aortic dissection with ARSA. A 46‑year‑old male was admitted to Beijing Anzhen Hospital b...

Twenty-six consecutive patients with pulsatile neck masses were studied with digital subtraction angiography (DSA) by venous injection, computed tomography (CT), and conventional direct angiography. The neck masses proved to be secondary to tortuous and ectatic carotid or subclavian arteries in 13 cases, resulted from subclavian artery aneurysms in three cases, and resulted from tumor in 10 cas...

Objectives- To provide a reference anatomy of the thoracic cavity vessels of the Rayini goat by using Computed tomography. Design- Experimented study. Animals- Five healthy Rayini goat. Procedures- Spiral CT images (with and without contrast media) were acquired from the thoracic region perpendicular to long axis of the body. CT windows were adjusted as necessary to have optimized images of ...

Variations of major arterial vessels are of clinical significance. The vertebral artery (VA) normally arises from the subclavian artery. The present report describes an anomalous origin of the left vertebral artery (LVA) from the aortic arch between the origin of the left subclavian and the left common carotid arteries. This artery was crossed superficially from medial to lateral by the left sy...

• Warner and Toronto have described a method for detecting and quantitating aortic regurgitation. This method involves simultaneous recording of indicator dilution curves from the left radial and femoral arteries following injections, at specific phases of the cardiac cycle, into the descending aorta at and downstream from the origin of the left subclavian artery. From these measurements they d...

This report describes a solution for a restenosis and for the fracture of a stent in the vertebral artery in a patient suffering from vertebrobasilar symptoms. Angiography demonstrates restenosis of a vertebral stent as well as its fracture and migration into the subclavian artery. This complication was managed percutaneously by passing a guide wire through the fractured stent. Pre-dilatation a...
