UHFUS Characterization of Normal Lymphatic Anatomy

NCT07677839 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 50

No results posted yet for this study

Summary

This is a prospective pilot study of breast cancer patients undergoing axillary lymph node dissection (ALND) or sentinel lymph node biopsy (SLNB). Participants will undergo ultra-high frequency ultrasound (UHFUS) imaging with indocyanine green (ICG) dye to map lymphatic channels between the wrist and elbow to investigate normal lymphatic anatomy in patients with breast cancer.

Conditions

Interventions

PROCEDURE

Indocyanine green (ICG) solution injection

0.1cc of 2.5 mg/cc Indocyanine green (ICG) solution will be injected intradermally at the 1st and 4th webspaces of the hand, and radial and ulnar volar wrist areas.

DEVICE

Ultra-High Frequency Ultrasound

UHFUS will capture still images at specific landmarks along the wrist-to-elbow axis to characterize lymphatic channels. The following quantitative data of lymphatic channels will be captured: 1\. Outer diameter (i.e., total diameter including wall and lumen); 2. Inner diameter (i.e., diameter of the lumen only); and 3. Wall thickness (i.e., the thickness of the lymphatic channel wall)
