Background: To evaluate Interventional Radiology (IR) procedural volume changes at a large Midwest health system between March 17, 2020 and April 30, 2020 following a state-mandated shutdown of nonessential procedures during the initial phase of COVID-19.

Methods: IR procedural volumes were compiled, stratified by location and compared with Diagnostic Radiology (DR) volumes during the same timeframe. Procedure volume was categorized by type, including oncology, dialysis interventions, and drainage procedures with comparisons made using Z-score test for proportions.

In the setting of portal hypertension, intractable bleeding from anorectal varices is a rare occurrence. In this review, clinical presentation and management of this dilemma are presented in a case-based fashion. Bleeding may occur in the absence of prior history of cirrhosis or gastroesophageal varices and measurement of hepatic venous pressure gradient and liver biopsy could help to establish the diagnosis.

Ultrasound has been established as an important diagnostic tool in assessing vascular abnormalities. Standard B-mode and Doppler techniques have inherent limitations with regards to detection of slow flow and small vasculature. Contrast-enhanced ultrasound (CEUS) is a complementary tool and is useful in assessing both the macro- and microvascular anatomy of the aorta.

Peritoneal Dialysis.

Semin Intervent Radiol

March 2016

Peritoneal dialysis is becoming more important in the management of patients with end-stage renal disease. Because of the efforts of the "Fistula First Breakthrough Initiative," dialysis venous access in the United States has become focused on promoting arteriovenous fistula creation and reducing the number of patients who start dialysis with a tunneled catheter. This is important because tunneled catheters can lead to infection, endocarditis, and early loss of more long-term access.

Study Design: Retrospective study of a consecutive series of patients undergoing lumbar spine magnetic resonance imaging (MRI) for low back pain at a single institution.

Objective: To determine the prevalence and nondetection rate of incidental extraspinal findings (IESFs) in adult patients undergoing MRI of the lumbar spine performed for low back pain by using a structured approach.

Summary Of Background Data: Extraspinal findings are depicted on lumbar spine magnetic resonance image.

Primary tumors of the major body veins arising intraluminally are rare clinical entities. As such, few cases have been reported in the literature. As a primary tumor, hemangiomas arising in the internal jugular vein are extremely rare, while those arising in the external jugular vein are only slightly more common.
