Correlation of CT Angiography and Technetium-Labeled Red Blood Cell Scintigraphy to Catheter Angiography for Lower Gastrointestinal Bleeding: A Single-Institution Experience.

Purpose: To investigate the correlation of computed tomography (CT) angiography and Technetium-labeled red blood cell (RBC) scintigraphy to catheter angiography (CA) in the management of lower gastrointestinal bleeding (LGIB) while considering potential nephrotoxic effects of iodinated contrast.

Materials And Methods: From November 2012 to August 2017, 223 CAs performed for LGIB, including massive, ongoing, and obscure bleeding, were retrospectively identified in patients with pre-procedural CT angiography or RBC scintigraphy. Positive correlations and sensitivities were calculated for CT angiography and RBC scintigraphy using CA results as reference.

Volumetric Assessment of Pediatric Vascular Malformations Using a Rapid, Hand-Held Three-Dimensional Imaging System.

The effect of percutaneous, surgical, and medical therapies for vascular malformations (VMs) is often difficult to quantify volumetrically using cross-sectional imaging. Volumetric measurement is often estimated with serial, expensive MRI examinations which may require sedation or anesthesia. We aim to explore whether a portable 3D scanning device is capable of rapid, accurate volumetric analysis of pediatric VMs.

Transsplenic splenoportography and portal venous interventions in pediatric patients.

Background: Data regarding transsplenic portal venous access for diagnostic imaging and endovascular intervention in children are limited, possibly due to concerns regarding high bleeding risks and resultant underutilization.

Objective: To investigate the safety and utility of transsplenic splenoportography and portal venous interventions in children.

Materials And Methods: A retrospective review was performed of all pediatric patients undergoing percutaneous transsplenic portal venous access and intervention at two large tertiary pediatric institutions between January 2012 and April 2017 was performed.

Management of Acute Lower Gastrointestinal Bleeding.

Acute lower gastrointestinal bleeding (LGIB), defined as hemorrhage into the gastrointestinal tract distal to the ligament of Treitz, is a major cause of morbidity and mortality among adults. Overall, mortality rates are estimated between 2.4% and 3.
