Virtual-assisted lung mapping using dual staining with indocyanine green and indigo carmine enhanced marking detectability.

ABSTRACT:

Background

Virtual-assisted lung mapping (VAL-MAP) is a preoperative bronchoscopic multispot dye-marking procedure to facilitate sublobar lung resection for unidentifiable lung nodules. To increase detectable markings, we performed VAL-MAP using dual staining (VAL-MAP DS) with indocyanine green (ICG) and indigo carmine. This study was designed to evaluate the efficacy and safety of the modified technique.

Methods

We retrospectively reviewed the records of patients who underwent VAL-MAP DS. Twenty patients with 27 lesions underwent 72 VAL-MAP DS markings. We investigated the overall detectable marking rate, visible marking rate, successful resection rate, and complications.

Results

The overall detectable marking rate, thanks to both ICG and indigo carmine, tended to be
