“…Similar findings have been recently published for the technique of pre-operative CT-guided microcoil placement and resection with or without intraoperative fluoroscopy (8)(9)(10). Successful use of embolization coils has also been reported in several small series (11)(12)(13), Similar techniques have been described, with pre-operative CT-guided insertion of radiopaque markers attached to sutures that lie on the surface of the lung (14,15), placement of metallic clips (16), fragmented coils (17). One series describes intentional creation of a pneumothorax during the coil placement, by inserted a pigtail catheter to instil air into the pleural space.…”

Background: Video-assisted thoracoscopic surgery (VATS) is standard of care for small lung resections at many centres. Computed tomography (CT)-guided insertion of microcoils can aid surgeons in performing VATS resections for non-palpable lung nodules deep to the lung surface.Methods: Retrospective analysis of CT-guided microcoil insertions prior to VATS lung resection at a single institution from October 2008 to January 2014.Results: A total of 63 patients were included (37% male, mean age 61.6±11.4 years). Forty-two patients (67%) had a history of smoking, with 10 current smokers. Sixty one (97%) patients underwent wedge resection and 3 (5%) patients had segmentectomy. Three (5%) patients required intra-operative staple line re-resection for positive or close margins. Eleven (17%) patients had a completion lobectomy, 5 of which were during the same anaesthetic. The average time between the CT-guided insertion and start of operation was 136.6±89.0 min, and average operative time was 84.0±53.3 min. The intra-operative complication rate was 5% (n=3), including 1 episode of hemoptysis, and 2 conversions to thoracotomy. The post-operative complication rate was 8% (5 patients), and included 2 air leaks, 1 hemothorax (drop in hemoglobin), 1 post chest tube removal pneumothorax, and one venous infarction of the lingula after lingula-sparing lobectomy requiring completion lobectomy. . Average post-operative length of stay was 2.2 days. A diagnosis was made for all patients.Conclusions: CT-guided microcoil insertion followed by VATS lobectomy is safe, with short operative times, short length of stay and 100% diagnosis of small pulmonary nodules. This technique will become more important in the future with increasing numbers of small nodules detected on CT as part of lung cancer screening programs.

“…7 Reinschmidt et al reported localization of pulmonary nodules using suture-ligated microcoils in 2001. 8 The study is a pioneer attempt to test the microcoil positioning method that included five patients, which may need further research to investigate its advantages. Rodrigues et al demonstrated that VATS and CT-guided microcoil localization was associated with excellent recurrence-free survival for superficial premalignant, minimally invasive, and small invasive lung tumors.…”

Background The localization of small pulmonary nodules (SPNs) during video-assisted thoracoscopic surgery (VATS) is challenging thoracic surgeon, especially in patients with severe pleural adhesion or visceral pleura pigmentation due to low success rate and future conversion to thoracotomy. This study aims to compare the efficacy and safety between modified microcoil and methylene blue in preoperative localization of small nodules, particularly patients with severe pleural adhesion or visceral pleura pigmentation. Materials and Methods From January 2018 to February 2019 in our institute, 342 patients who underwent computed tomography-guided localization of SPN were recruited in this retrospective cohort study and divided into the modified microcoil group (n = 239) and the methylene blue group (n = 103) according to the localization method. Clinical characteristics and perioperative complications were collected to analyze. Results All SPNs were successfully marked in both groups. Location-related complications, the duration of localization procedure, and the length of hospital stay were not different between the two groups. The operation time of modified microcoil and the duration of removal of nodule in operation were both shorter than the methylene blue (p = 0.014 and p = 0.047). The analysis stratified by gender showed that similar results were found in male patients (p = 0.01 and p = 0.00), while in female patients, no significant difference was found. Additionally, in senior patients (older than 60 years), the operation time in modified microcoil groups was less than methylene blue group (p = 0.024). Conclusion Compared with methylene blue, modified microcoil achieved a shorter operation time of removal of nodule in VATS, especially for patients with pleural adhesion and the pigmentation of the lung surface as well as the male patients and the patients older than 60 years.

“…The third group of preoperative targeting techniques involves percutaneous hook-wire [6][7][8][9][10][11] or wire coil devices [8,28,29]. Percutaneous localization using a mammographic needle and hook wire is one of the oldest and most common methods [6].…”

“…All hook wires cause damage to the lung parenchyma if dislodged [31], and massive air embolism has been reported [32]. Modifications of this technique using short hook wires and short platinum microcoils [28] attached to sutures have been reported, with limited success.…”

Platinum microcoils were placed in porcine lungs to determine the feasibility for use as a lung nodule marker. Using computed tomography (CT) guidance, the microcoils were successfully deployed in 17 out of 19 attempts. Coil deployment depth ranged from 7 mm to 34 mm below the pleural surface. Moderate pneumothorax was detected after 3 of 19 microcoil insertions. No hemothorax or significant pulmonary hemorrhage was noted. Fluoroscopic guided thoracoscopic resection was successful in 10 of 12 attempts. Platinum microcoils can be safely and easily deployed into the lung parenchyma with minimal complication risk, and can be used to guide subsequent thoracoscopic wedge resection.
