Right cervical aortic arch and pseudocoarctation of the aorta associated with aneurysms and steal phenomena: US, CTA, and MRA findings.

A 55-year-old woman presented with right cervical aortic arch with pseudocoarctation of the aorta further complicated by the presence of multiple aneurysms and a high-grade stenosis at the origin of the left subclavian trunk from the aorta causing a discrepancy in blood pressure between the right and left arms. The branching pattern and the resulting complex steal syndromes involving the left carotid and the subclavian system are unique. The computed tomography angiography, magnetic resonance angiography, and Doppler ultrasound findings are described.

[Effect of propranolol on renal hemodynamics in patients with cirrhosis: assessment with Doppler US].

Purpose: To determine the renal resistive index profile in cirrhotic patients before and after propranolol treatment and assess the effects of propranolol on renal hemodynamics.

Materials And Methods: Thirty-six patients with cirrhosis and ascites (decompensated group), 39 patients with cirrhosis but no ascites (compensated group) and 25 patients with normal renal and hepatic functions (control group) were studied. All had normal blood urea nitrogen and serum creatinine levels.

Intrarenal arteriovenous fistula causing a "pseudonutcracker effect".

We report a case in which an intrarenal arteriovenous fistula caused the nutcracker effect. Color Doppler sonography of the left renal artery showed a peak systolic velocity of 150 cm/second and renoaortic ratio of 2.1.
