Abstract
Preoperative detection of the arteria praebronchialis (AP), a rare variant mediastinal branch of the left pulmonary artery, can be crucial to a successful left-lung surgery; if the AP is overlooked and ligated during surgery, the blood supply to the remaining lobe may be compromised. The purpose of this study was to update the incidence and branching patterns of the AP. From 18 April 2012 to 31 December 2022, contrast-enhanced CT was screened by one radiologist for the presence of AP. Branching patterns of the AP were analyzed by three thoracic radiologists. The incidence of AP was updated to 0.068% (18/26,310) from the previously reported 0.03%; the incidence of AP for male and female patients was 0.110% and 0.017%, respectively. AP supplied only the LLL in 10 cases and both the lingular division of LUL and LLL in nine cases. Dual segmental supply by both the AP and the normal left descending pulmonary artery existed in 15 cases; exclusive segmental supply by either artery existed in four cases. The AP supplies either the LLL alone or both LLL and the lingular division of LUL, and its incidence is not negligible in the male population, necessitating routine surveillance prior to pulmonary resection.

[PMID: 37151862 PMCID: PMC10157644 DOI: 10.3389/fsurg.2023.1173602] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Accepted: 03/27/2023] [Indexed: 05/09/2023] Open
Abstract
Background With the development of anatomical segmentectomy, the thoracic surgeons must master the anatomical variations of the pulmonary bronchi and vessels. However, there are only a few reports showing anatomic variations of the lingular segment (LS) using three-dimensional computed tomography bronchography and angiography (3D-CTBA). Thus, the present study aimed to analyze the bronchovascular patterns of the LS and explore the correlation between the lingular segment artery (LSA) and left superior division veins (LSDV). Materials and methods The 3D-CTBA data of the left upper lobe (LUL) were collected from patients who had undergone lobectomy or segmentectomy at Hebei General Hospital between October 2020 and October 2022. We reviewed the clinical characteristics and variations in bronchi and pulmonary vessels and grouped them according to different classifications. Results Among all 540 cases of 3D-CTBA, the branching patterns of LSA included 369 (68.3%) cases with the interlobar origin, 126 (23.3%) cases with the interlobar and mediastinal origin, and 45 (8.3%) cases with the mediastinal origin. The branching pattern of LSDV could be classified into three forms: Semi-central vein type (345/540, 63.9%), Non-central vein type (76/540, 14.1%), and Central vein type (119/540, 22.0%). There were 51 cases (9.4%) with Non-central vein type, 50 cases (9.3%) with Central vein type, 268 cases (49.6%) with Semi-central vein type in the interlobar type, and 7 cases (1.3%) with Non-central vein type, 9 cases (1.7%) with Central vein type, 29 cases (5.4%) with Semi-central vein type in the mediastinal type. Moreover, the Non-central vein type, the Central vein type, and the Semi-central vein type accounted for 18 (3.3%), 60 (11.1%), and 48 (8.9%) in the interlobar and mediastinal type. Combinations of the branching patterns of the LSA and LSDV were significantly dependent (p < 0.005). The combinations of the interlobar and mediastinal type with the Central vein type, and the interlobar type and the mediastinal type with the Semi-central vein type were frequently observed. Conclusions This study found the relationship between the LSA and LSDV and clarified the bifurcation patterns of the bronchovascular in the LS. Our data can be used by thoracic surgeons to perform safe and precise LS segmentectomy.

Abstract
BACKGROUND For thoracic surgeons, three-dimensional computed tomography bronchography and angiography (3-DCTBA) is a convenient way to analyze pulmonary variations before segmentectomy. Mediastinal lingular artery (MLA) is one of the representative variations. METHODS The 3-DCTBA data of left upper lobe (LUL) were collected from patients who underwent pulmonary surgery from January 2018 to December 2019. We reviewed the patterns of bronchi and pulmonary vessels and grouped them according to different classifications. RESULTS Among all the 404 cases of 3-DCTBA, mediastinal lingular artery (MLA) was found in 107 cases (26.49%). The patterns of B3 and the vein in left upper division (LUD) are distinct between mediastinal (M-type) group and interlobar (IL-type) group. The patterns of bronchi and veins in lingular division, as well as the pattern of pulmonary artery in LUD, have no differences between M-type and IL-type groups. CONCLUSIONS Mediastinal lingular artery is speculated to originate from the variation of B3, and the MLA independently influences the venous pattern in LUD in turn.

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 in 46.39% of cases, and 3 arteries in 8.43% of cases. The branching patterns of the lingular artery included 119 (71.68%) cases with interlobar origin, 35 (21.08%) cases with interlobar and mediastinal origin, and 13 (7.83%) cases with mediastinal origin. The interlobar lingular artery include superior lingular artery (A4) and inferior lingular artery (A5). The interlobar lingular artery type was A4a, A4b, A5 in 7.23% of cases; A4 and A4b+5 in 3.01% of cases; and A4b and A4a+5 in 4.82% of cases. The mediastinal lingular artery was divided into the following 5 types: 'A4', 'A4b', 'A4b+5', 'A4b+5a', and 'A4+5'. The most common type was A4 (12.05%, 20/166) in 166 patients. The interlobar lingular artery had the following 5 patterns of variation: 'A4+5', 'A4, A5', 'A4a, A4b, A5', 'A4a, A4b+5', and 'A4b, A4a+5'. The single interlobar lingular artery (A4+5) was the most common type in 38.55% of cases. In 24.10% of cases, A5 came from A8 or A8+9. Besides In 8.43% of cases, the origin of A5 was close to A8 or A8+9. Conclusions We identified the left various lingular artery branching patterns with 3D-CTAB in patients and defined the frequency of anatomic variations. 3D-CTAB is useful for finding these variations.

ANNALS OF TRANSLATIONAL MEDICINE 2021; 9:325.

Abstract
Background Sarcopenia characterized by skeletal muscle loss may influence postoperative outcomes through physical decline and weakened immunity. We aimed to investigate clinical significance of sarcopenia in resected early-stage non-small cell lung cancer (NSCLC). Methods We retrospectively reviewed 315 consecutive patients with pathologic stage I NSCLC who had undergone lobectomy with systematic nodal dissection. Sarcopenia was defined as the lowest quartile of psoas muscle area on the 3rd vertebra on the high-resolution computed tomography (HRCT) image. Clinicopathological variables were used to investigate the correlation to postoperative complications as well as overall and recurrence-free survival. Results Upon multivariable analysis, male sex [odds ratio (OR) =5.780, 95% confidence interval (CI): 2.681–12.500, P<0.001], and sarcopenia (OR =21.00, 95% CI: 10.30–42.80, P<0.001) were independently associated with postoperative complications. The sarcopenia group showed significantly lower 5-over all survival (84.4% vs. 69.1%, P<0.001) and recurrence-free survival (77.2% vs. 62.0%, P<0.001) comparing with the non-sarcopenia group. In a multivariable analysis, sarcopenia was an independent prognostic factor [hazard ratio (HR) =1.978, 95% CI: 1.177–3.326, P=0.010] together with age ≥70 years (HR =1.956, 95% CI: 1.141–3.351, P=0.015) and non-adenocarcinoma histology (HR =1.958, 95% CI: 1.159–3.301, P=0.016). Conclusions This is the first study which demonstrates that preoperative sarcopenia is significantly associated with unfavorable postoperative complications as well as long-term survival in pathologic stage I NSCLC. This readily available factor on HRCT may provide valuable information to consider possible choice of surgical procedure and perioperative management.
