Endovascular Treatment of Congenital Portosystemic Shunt: A Single-Center Prospective Study.

Purpose: To design a prospective study on endovascular closure of congenital portosystemic shunts. The primary endpoint was to assess the safety of endovascular closure. The secondary endpoint was to evaluate the clinical, analytical and imaging outcomes of treatment.

Endovascular Closure Resolves Trimethylaminuria Caused by Congenital Portosystemic Shunts.

This study aimed to report three new cases of an association between two rare conditions, congenital portosystemic shunts (CPSS) and trimethylaminuria (TMAU), and the efficacy of endovascular closure of the CPSS for resolving TMAU. Between November 2014 and April 2017, 15 patients with CPSS were enrolled in this prospective study to assess the efficacy of percutaneous endovascular shunt closure. Three patients presented with clinical symptoms of TMAU that were confirmed by urine analysis of trimethylamine (TMA) and TMA n-oxide.

Validation of the Position of Injection Needles with Contrast-Enhanced Ultrasound for Dynamic Contract-Enhanced MR Lymphangiography.

Purpose: To assess the feasibility of validating the position of the needle in groin lymph nodes using injection of ultrasound (US) contrast prior to magnetic resonance (MR) lymphangiography.

Materials And Methods: In 28 patients (average age, 52 y; 15 women, 13 men), 25G needles were placed in bilateral groin lymph nodes using US guidance outside the MR suite. The confirmation of the position of the needles in lymph nodes and efferent lymphatic flow was performed by injecting 1 mL of the US contrast agent (Lumason) mixed with 2 mL of lidocaine and observing contrast enhancement of the efferent lymphatic ducts leading to the pelvis from the lymph node.
