Analysis of anatomical variations of the lingular artery of the left upper lobe using 3D computed tomography angiography and bronchography.

ABSTRACT:

Background

Thoracic surgeons must be familiar with the anatomy of the pulmonary artery during segmentectomy and segmentectomy. But pulmonary arteries have numerous variations and aberrant branching patterns. The purpose of the present study was to analyze the anatomical variations and frequencies of the lingular artery of the left upper lobe (LUL) using 3D computed tomography angiography and bronchography (3D-CTAB).

Methods

We retrospectively studied 166 patients having undergone lobectomy or segmentectomy from January to December 2020 at Fujian Medical University Cancer Hospital's Department of Thoracic Surgery. All patients underwent 3D reconstruction using 3D-CTAB before surgery.

Results

The lingular segment was supplied by 1 artery in 45.18% of cases, 2 arteries i
