The Graduate School of Medicine at Chiba University is planning to introduce computed tomography (CT) images of donated cadavers to the gross anatomy laboratory. Here we describe an anomaly of the right subclavian artery that was detected by interpretation of CT images prior to dissection. The anomaly was verified to be the right subclavian artery, as the last branch of the aortic arch, by subs...

BACKGROUND AND PURPOSE We report a management strategy for cerebral revascularization in a patient with an occluded common carotid artery by first performing a subclavian to external carotid artery bypass, followed by superficial temporal artery middle cerebral artery (STA-MCA) bypass. METHODS The patient presented with symptomatic left hemispheric hemodynamic insufficiency, associated with o...

the thyrocervical trunk most commonly arises from the upper portion of the first segment of the subclavian artery, close to the medial edge of the scalenus anterior muscle and after short distance is divided to the inferior thyroid, transverse cervical, and suprascapular artery. this study reports important variations in branches of the thyrocervical trunk in a singular female cadaver. on the r...

Background  An aberrant right subclavian artery (RSA) or arteria lusoria is the most common congenital abnormality of the aortic arch with an incidence of 0.3 to 3.0%. Case Description  We report a case of a perforated aneurysmal aberrant RSA, managed using a hybrid approach. Conclusion  In emergency cases with acute bleeding, we recommend an endovascular approach to avoid the lethal sequel of ...

Tracheomalacia is one of the rarest etiologies of chronic cough. Herein, we present the case of an elderly woman with chronic cough who on detailed evaluation was found to have focal (localized) tracheomalacia due to compression by an aberrant right subclavian artery (arteria lusoria). The absence of dysphagia in this patient also deserves particular mention.

Coronary-subclavian steal syndrome is a rare clinical entity, which results from the atherosclerotic disease of the origin of the subclavian artery in patients in which the internal mammary artery was used as a conduit for coronary artery by-pass. This complication causes reversal of the flow in the internal mammary artery and the recurrence of myocardial ischemia. The therapeutic options are a...

Aneurysms of the internal mammary artery are extremely rare. Immediate treatment is necessary because of the high risk of rupture that can be life-threatening. Here we describe a case of idiopathic internal mammary artery aneurysm in a 54-year-old woman in the setting of aberrant right subclavian artery. The aneurysm was successfully treated with coil embolization without complications.

OBJECTIVES The repair of extensive thoraco-abdominal aortic aneurysms (TAAAs) is invasive and carries a high risk for spinal cord injury (SCI). The aim of this study was to assess the early results and collateral circulation to the spinal cord after hybrid repair for Crawford extent II aortic aneurysms. METHODS Between 1997 and 2013, we performed 128 thoracic endovascular aortic repair (TEVAR...

PURPOSE To evaluate the feasibility and safety of Guglielmi detachable coils for endovascular treatment of extracranial aneurysm and arteriovenous fistula. MATERIALS AND METHODS Embolization with Guglielmi detachable coils delivered through Tracker-18 microcatheters was performed in 16 patients. This patient group had eight renal artery aneurysms and 11 arteriovenous fistulas (three cases of ...

A 69-year-old woman with syncopes and recently diagnosed hypertrophic cardiomyopathy was referred to our imaging unit to complete a cardiac magnetic resonance study. This confirmed the hypertrophic cardiomyopathy (mediobasal septum 17 mm) with left ventricular outflow tract obstruction and anterior systolic motion of the mitral valve (Figure 1). In the anatomical axial planes, we observed an im...
