# Sleeve basal segmentectomy with pulmonary artery division for lung cancer: how to do it

## TL;DR

A new surgical technique called sleeve basal segmentectomy is described for lung cancer patients who cannot undergo standard procedures.

## Contribution

The paper introduces a novel surgical approach involving pulmonary artery division to facilitate bronchial reconstruction in lung cancer surgery.

## Key findings

- Sleeve basal segmentectomy was successfully performed in an immunocompromised patient with squamous cell carcinoma.
- Dividing and reconstructing A6 provided sufficient exposure for complex bronchial anastomosis.
- The technique may help minimize blood flow disruption during bronchial reconstructions.

## Abstract

Sleeve segmentectomy was originally developed to preserve the lung volume in patients who were unable to tolerate lobectomy. We herein report an immunocompromised patient with potentially curable peripheral squamous cell carcinoma in whom sleeve basal segmentectomy was performed for a 1.8-cm tumor with endobronchial growth that occluded B7 and invaded the inlet of the middle lobar bronchus and B6. To provide sufficient surgical exposure for complex double-barrel reconstruction after segmentectomy, A6 was divided and reconstructed after the anastomosis was complete. This technique may be applicable to other peripheral bronchial reconstructions to minimize blood flow disruption to bronchial anastomosis.
