Background and Objective Pulmonary vascular variations are a major factor in thoracic surgeries. Minimally invasive techniques, such as video-assisted thoracic surgery (VATS) used in non-small lung cancer treatment, have a limited field of view and no haptic feedback. Additionally, new studies suggest that segmentectomies are beneficial for patients. Accurate knowledge of vascular patterns and variants is crucial for conducting such procedures safely. The aim of this review was to systematize data in a useful manner from studies and case reports concerning pulmonary vascular variations and patterns. Methods We conducted a search on the PubMed and Embase databases. We used classifications of Nagashima, Yamashita, Boyden, Maciejewski, and Shimizu. Key Content and Findings The analysis showed that more data on the incidence rate and vascular patterns of certain bronchopulmonary segments are needed. Venous variations are a major factor in segmental resections, but additional data regarding incidence and pattern types are needed. Surgeons need to be aware of vascular variations as they can influence procedures in seemingly unrelated areas. The majority of studies emphasize the use of three-dimensional (3D) reconstruction of computed tomography (CT) for accurate planning of any thoracic procedures. Conclusions Abnormal vessels pose a risk in various procedures performed within the thorax, and the data in this review could be valuable in different medical areas in this regard.

Background: Knowledge of the anatomy of pulmonary arteries is essential in many invasive procedures concerning pulmonary circulation. In the diagnosis and treatment of chronic thromboembolic pulmonary hypertension (CTEPH), two-dimensional (2D) pulmonary angiography is used. Recognizing the topographic course of the pulmonary arteries and understanding the status in three dimensions (3D) is paramount. This study aimed to evaluate and describe the branching variant of pulmonary arteries in a single case, as well as morphological parameters of the segmental arteries, like length, diameter and branching angles. Methods: One pair of embalmed human cadaver lungs was dissected by a scalpel and surgical forceps and was measured up to the subsegmental arteries. Results: The diameters (ranging from 3.04 to 9.29 mm) and lengths (ranging from 9.09 to 53.91 mm) of the pulmonary segmental arteries varied. The proximal branching angles were wide and close to perpendicular, while distally, the angles between the segmental and subsegmental arteries were narrower (30–45°). Upon evaluating the branching, rare variations were identified and delineated, notably in the lower lobes of both lungs. Conclusions: Utilizing knowledge and data in clinical settings is instrumental for effectively diagnosing and treating CTEPH. Further research is required to explore the complications in invasive procedures related to various anatomical variations.
