Background: A hook wire has been most widely used for computed tomography (CT)-guided localization before video-assisted thoracoscopic surgery (VATS). However, microcoils have been suggested to replace wires. The purpose of this study was to compare the efficacy, VATS procedure time, and excised volume of specimens of CT-guided localization using a hook wire and microcoil.
Methods: The medical records of 106 patients with 110 pulmonary nodules who underwent CT-guided localization using a hook wire (group A) or microcoil (group B) before VATS performed between March 2013 and January 2017 were retrospectively reviewed.
Results: The procedure success rate was 100% in both groups. Dislodgement occurred in four patients in group A and not in group B. Patient pain score was significantly lower for group B than group A (4.0 vs. 6.3; P < 0.001). The VATS success rate was higher in group B than in group A (98.1% vs. 91.1%; P = 0.174). The VATS procedure time was significantly shorter for group B than group A (18.8 vs. 23.6 minutes; P = 0.004). The excised volume of surgical specimens was significantly smaller for group B than group A (8.5 vs. 11.7 cm ; P = 0.043). No major complications related to the localization procedure were noted in either group.
Conclusions: This study showed similar effectiveness of VATS localization between groups. However, microcoil is superior to hook wire for localization of pulmonary nodules in terms of VATS procedure time and excised volume of surgical specimens, with the advantages of no dislodgement and less patient pain.

Background: With advancements in imaging testing and surgical procedures, an increasing number of nodules with smaller diameters and deeper locations have been deemed suitable for surgical intervention. The preoperative localization of these nodules has become essential. In this retrospective single-center study, we aimed to compare the effectiveness and patient comfort associated with the use of a four-hook needle versus a hook-wire needle for preoperative localization.

Considering the fault tolerance of EMB (Electro-Mechanical-Brake) braking failure and anti-rollover control at the same time is one of the urgent problems to be solved in the driving safety of X-by-wire vehicles. Accurate rollover index is a key part of anti-rollover control. Aiming at the problem that the traditional rollover index reflects that the unsprung mass of the vehicle is insufficiently affected by road excitation, a tripped vehicle rollover dynamic model is established based on single-wheel braking failure, and a rollover evaluation index NLTR (New Load-Transfer-Rate) suitable for braking failure is proposed.

Background And Objective: The early detection and early treatment of high-risk pulmonary nodules directly affect the long-term survival rate of patients. However, conventional nodule localization methods, such as hook-wire, technetium-99m, and methylene blue are associated with issues such as a high-frequency of complications, low patient tolerance, serious side effects, and inability to identify pigmented lungs. For patients who require segmentectomy, there is often a lack of effective path planning, resulting in insufficient resection margins or excessive loss of lung function.

Background: Pain is a relatively common complication after hook-wire puncture localization. However, the problem of pain occurrence following this localization procedure has not been sufficiently examined. In this prospective study, we aimed to investigate the incidence and risk factors associated with acute pain after preoperative CT-guided hook-wire puncture localization of pulmonary nodules.

Multiple techniques exist for the preoperative localization of small, deeply located solid or subsolid pulmonary nodules to guide limited thoracoscopic resection. This study aims to conduct a multi-institutional comparison of three different tomography-guided tracers' methods. A retrospective multicenter cross-sectional study was conducted.
