High-quality 3-dimensional image simulation for pulmonary lobectomy and segmentectomy: results of preoperative assessment of pulmonary vessels and short-term surgical outcomes in consecutive patients undergoing video-assisted thoracic surgery†

Abstract

High-quality 3D-CT images clearly revealed the anatomies of pulmonary vessels, which could play important roles in safe and efficient VATS anatomical resection.

Comparative study of three‐dimensional versus two‐dimensional video‐assisted thoracoscopic two‐port lobectomy

“…The Einstein Vision 3D endoscopic systems that we used can achieve an optical magnification of 10–15 times, while the Karl Storz 2D systems can only deliver an optical magnification of about four times. Therefore, surgery using a 3D system is more precise and, thus, safer 14. The 3D vision allows surgeons to be present virtually “in” the scene, rather than just seeing a photo of it, thereby creating a much stronger sense of depth and position that can reduce the incidence of injury to important organs or tissues 14, 15.…”

3D CT simulation in minimally invasive thoracic surgery

“…In this case, a small branch of pulmonary artery around the bronchus of the lingual segment left unidentified at the time of operation resulted in the injury of PA and conversion to the thoracotomy ( Figure 5). The identification rate of the branch of the pulmonary artery reportedly ranged from 95.1% to 98.7% (4,7,10). Artery with small caliber (smaller than 2 mm) tended to be unidentified, and identification rate was likely low in the branches of the right upper pulmonary artery (7).…”

“…The identification rate of the branch of the pulmonary artery reportedly ranged from 95.1% to 98.7% (4,7,10). Artery with small caliber (smaller than 2 mm) tended to be unidentified, and identification rate was likely low in the branches of the right upper pulmonary artery (7). Some of the unidentified branches by the volume rendering could be detected by careful reading of 0.625 mm contrast enhanced study (7) and to get optimal result in processing the vascular images, careful timing and dose of the injection of the contrast medium is important (1,11).…”

Possibilities of Three-Dimensional Computer Simulation of Pulmonary Vessels Based on Computed Tomographic Angiopulmonography Data in the Planning of Video-Assisted Segmentectomy of Lungs

“…Немногочисленные ложноотрица-тельные результаты были обусловлены малым диаметром ветвей легочных артерий, был опре-делен порог в 2 мм [11 -13]. Также исследова-телями было отмечено уменьшение объема кро-вопотери и длительности оперативного вмеша-тельства у пациентов, которым было выполнено трехмерное моделирование легочных сосудов по сравнению с теми пациентами, у кого оно не проводилось [13].…”
