Abstract:
Objective To explore the clinical applications of 3D-CT reconstruction combined with 3D printing in the analysis of anatomical types and variations of bilateral pulmonary arteries. Methods From January 2019 to February 2022, the clinical data of 547 patients who underwent anatomical lung lesion resection in our hospital were retrospectively collected. They were divided into a 3D-CT reconstruction plus printing technology group (n=298, 87 males and 211 females aged 53.84±12.94 years), a 3D-CT reconstruction group (n=148, 55 males and 93 females aged 54.21±11.39 years), and a non-3D group (n=101, 28 males and 73 females aged 53.17±10.60 years). Results In the 3D-CT reconstruction plus printing technology group, the operation time of patients (right: 125.61±20.99 min, left: 119.26±28.44 min) was shorter than that in the 3D-CT reconstruction group (right: 130.48±11.28 min, left: 125.51±10.59 min) and non-3D group (right: 134.45±10.20 min, left: 130.44±9.53 min), which was not associated with the site of surgery; intraoperative blood loss (right: 20.92±8.22 mL, left: 16.85±10.43 mL) was not statistically different compared with the 3D-CT reconstruction group (right: 21.13±8.97 mL, left: 19.09±7.01 mL), but was less than that of the non-3D group (right: 24.44±10.72 mL, left: 23.72±11.45 mL). Variation was found in the right pulmonary artery of 7 (3.91%) patients and in the left pulmonary artery of 21 (17.65%) patients. We first found four-branched lingual pulmonary artery in 2 patients. Conclusion Preoperative CT image computer-assisted 3D reconstruction combined with 3D printing technology can help surgeons to formulate accurate surgical plans, shorten operation time and reduce intraoperative blood loss.
