Incrementally Expandable Transjugular Intrahepatic Portosystemic Shunts: Single-Center Experience.

Objective: The purpose of this study is to investigate the long-term safety and efficacy of a small-diameter expandable transjugular intrahepatic portosystemic shunt (TIPS) in the management of portal hypertension.

Materials And Methods: This single-center retrospective study included 28 patients (12 women and 16 men; mean age, 56.9 years) who underwent small-diameter expandable TIPS creation between 2008 and 2010 for refractory ascites (n = 15; mean [± SD] model for end-stage liver disease [MELD] score, 15.

Computed Tomography Angiography of the Extremities in Emergencies.

Computed tomography angiography (CTA) of the extremities offers a noninvasive, rapid means of evaluation of the extremities in vascular emergencies. CTA is now the first-line investigation for this purpose, offering high sensitivity and specificity in diagnosis. The learning objectives of this review article include reviewing normal arterial anatomy and variants of the upper and lower extremity, illustrating CTA findings in traumatic vascular injuries, and exploring the range of vascular pathologies that may cause acute ischemic symptoms in the extremities.

Ovarian Torsion: Multimodality Review of Imaging Characteristics.

We present a case of ovarian torsion in pregnancy with demonstration of vascular flow on sequential Doppler ultrasonography. Magnetic resonance imaging demonstrated ovarian enlargement and edema. Mild symptoms and low clinical suspicion, in addition to risks associated with pregnancy prevented early laparoscopic examination, though torsion was considered.
