Purpose. To determine the possibilities of three-dimensional computer simulation of pulmonary vessels based on computed tomographic angiopulmonography data in the lung angioarchitectonics estimation in patients with planned video-assisted segmentectomy of lung. Materials and methods. The prospective study included 52 patients with 61 planned and performed video-assisted segmentectomy for peripheral lung mass lesions. In all the cases 3D computer simulation of pulmonary vessels based on computed tomographic angi-opulmonography with optimised scanning protocol data was performed. The results of 3D computer simulation were compared to the intraoperative surgical revision data, the number of pulmonary arteries was estimated in the region of interest. Results. By means of 3D computer simulation of pulmonary vessels data, 253 (96,9%) of 261 pulmonary arteries branches detected during intraoperative revision were successfully visualized at the preoperative stage. 66 (92,9%) of 71 branches were detected during the planning stage of the upper segmentectomies on the right, 66 (95,6%) of 69 branches – during the planning stage of the upper segmentectomies on the left, 64 (100%) of 64 branches – during the planning stage of the lower segmentectomies on the right, 57(100%) of 57 branches – during the planning stage of the lower segmentectomies on the left. Conclusion. 3D computer simulation of pulmonary vessels data was consistent with intraoperative revision results in the vast majority of cases, with rare false-negative results, related to the small vessels diameter observed only in case of upper segmentectomies. 3D computer simulation of pulmonary vessels is a sensitive method, which allows highly effective estimation of the angioarchitectonics in the area of interest, and that is, without a doubt, crucial in case of video-assisted technique.
