Shear Wave Elastograph and Contrast Enhanced Ultrasound for the Treatment of Lymphedema

Overview

About this study

Lymphaticovenous anstomosis is an effective surgery to treat lymphedema in the upper extremities secondary to cancer treatment. A crucial step is to identify patent lymphatic channels. Contrast enhanced ultrasound (CEUS) with intradermal injection of microbubbles is a promising method for lymphatic mapping in the upper extrmeities with lymphedema. The goals of the study are(1) to establish the preferred FDA approved microbubble agent (Lumason, Optison, Definity) for CEUS lymphatic mapping, (2) to identify lymphatic channels with CEUS and high-frequency ultrasound in patients receiving lymphaticovenous anastomosis surgery for upper extremity lymphedema, (3) and to validate the use of shear wave elastography for detecting improving in lymphedema prospectively.
