Virtual-reality robot-assisted inferior vena cava thrombectomy using virtual vascular endoscopy to identify inferior vena cava invasion.

ABSTRACT:

Objective

Partial or segmental inferior vena cava (IVC) resection is indicated for tumor control in patients with renal tumors invading the IVC. This study aimed to introduce a virtual vascular endoscope to assist surgeons in locating IVC invasion, formulate a surgical plan for robot-assisted IVC thrombectomy (RA-IVCT), and evaluate its potential value.

Methods

The reconstruction involves building the construction of deep learning models to predict IVC invasion, which were evaluated via intraoperative findings and pathological analysis. Thirty-six patients with renal tumors and IVC thrombi who underwent RA-IVCT between June 2016 and March 2022 were included in the study. A virtual vascular endoscopy was performed based on preoperative CT findings to identify IVC invasion. Ba
