Treating Myomatous Erythrocytosis Syndrome With Uterine Artery Embolization.

Background: Myomatous erythrocytosis syndrome, a form of secondary polycythemia associated with uterine leiomyomas, increases the risk of thrombosis and traditionally has been treated with hysterectomy.

Case: The patient is a 68-year-old woman with 7-year history of polycythemia initially thought to be secondary to a gastrointestinal stromal tumor that persisted after resection. A subsequent search for an alternative etiology led to the discovery of an 11.

The Value of Needle-Guidance Technology in Ultrasound-Guided Percutaneous Procedures Performed by Radiology Residents: A Comparison of Freehand, In-Plane, Fixed-Angle, and Electromagnetic Needle Tracking Techniques.

Objectives: Radiology residents typically learn ultrasound-guided procedures by performing supervised procedures on patients who may experience longer procedure times and higher complication rates. The purpose of this study was to determine if existing technologies, such as in-plane, fixed-angle guidance (IPFA) and electromagnetic needle tracking (ENT), can improve resident procedure time and accuracy.

Methods: Radiology residents (18 total) were randomized to 1 of 3 ultrasound-guidance technique groups-freehand, IPFA, or ENT-and instructed to place a needle into 4 liver lesions in a humanoid phantom, each increasing in difficulty.
