Abstract

Abstract:

Objective:

Before video-assisted thoracoscope surgery (VATS) , CT-guided percutaneous wire mesh was used to locate the pulmonary nodules accurately and to analyze the accuracy and safety of surgically removing the focal lesions.

Methods:

The patients with small pulmonary nodules (36 cases) from March 2016 to March 2018 in Pu'er People's Hospital were collected, all cases were using the CT-guided percutaneous puncture wire claw localization in small pulmonary nodules, then VATS was performed to resect the lesion, and the puncture success rate, localization time and complications were analyzed.

Results:

The diameter of pulmonary nodules in 36 patients was (15±10) mm, the success rate of CT-guided puncture localization was 100% (36/36) , and the localization time was (17.0±2.6) min. A small amount of pneumothorax was observed in 4 patients after positioning, and pulmonary compression was <5%. Seven patients presented a small amount of bleeding in the localization area, with the bleeding volume <10 ml, without special treatment. All the patients had a slight tingling when the puncture site was foreign body sensation or breathing after local anesthesia failure. No severe pain, pneumothorax, hemoptysis, severe cough and air embolism occurred. There was no shedding or displacement of the probe during VATS operation.

Conclusions:

Using CT-guided percutaneous puncture wire claw positioning for lesions before the resection of small pulmonary nodules was safe, and it can improve the accuracy of lesion resection of VATS.
