Abstract Background: Preoperative computed tomography (CT)-guided coil localization (CL) is commonly employed to facilitate the video-assisted thoracoscopic surgery (VATS)-guided diagnostic wedge resection (WR) of pulmonary nodules (PNs). When a scapular-blocked PN (SBPN) will be localized, the trans-scapular CL (TSCL) should be performed. In this study, we investigated the safety, feasibility, and clinical efficacy of preoperative CT-guided TSCL for SBPNs.Materials and Methods: From January 2014 to September 2020, a total of 152 patients with PNs underwent CT-guided CL prior to VATS-guided WR. Among them, 14 patients had the SBPNs and underwent TSCL procedure. Results: A total of 14 SBPNs were localized in the 14 patients. The mean diameter of the 14 SBPNs was 7.4 ± 2.4 mm. Technical success rate of puncture of the scapula was 100%. No complications occurred near the scapula. Technical success rate of CL was 92.9%. One coil dropped off when performing the VATS procedure. The mean duration of the TSCL was 14.2 ± 2.7 min. Two patient (14.3%) developed aysmptomatic pneumothorax after TSCL. Technical success rate of VATS-guided WR was 92.9%. The patient who experienced technical failure of TSCL directly underwent lobectomy. The mean VATS procedure duration and blood loss were 90.0 ± 42.4 min and 62.9 ± 37.2 ml, respectively. The final diagnoses of the 14 SBPNs included invasive adenocarcinoma (n = 4), adenocarcinoma in situ (n = 9), and benign (n = 1).Conclusions: Preoperative CT-guided TSCL can be safely and simply used to facilitate high successful rates of VATS-guided WR of SBPNs.

Background: Preoperative computed tomography (CT)-guided coil localization can increase the technical success of video-assisted thoracoscopic surgery (VATS)-guided diagnostic wedge resection of lung nodules relative to cases treated without localization. When multiple lung nodules (MLNs) are to be resected, preoperative localization for each lung nodule is required. The aim of this study was to explore the feasibility, safety, and clinical efficacy of preoperative CT-guided coil localization of MLNs. Methods: Between November 2015 and July 2019, 31 patients with MLNs were assessed via CT-guided coil localization followed by VATS-guided wedge resection. Rates of technical success for both the localization and wedge resection procedures, as well as data pertaining to patient complication rates and long-term outcomes were recorded and assessed. Results: In total, 68 nodules (average of 2.2 nodules/patient) were localized and resected using this approach. Nodules were unilateral and bilateral in 23 and 8 patients, respectively. The rate of CT-guided coil localization technical success for these nodules was 98.5% (67/68), with a technical success rate of single-stage coil localization on a per-patient basis of 96.8% (30/31). Following localization, asymptomatic pneumothorax occurred in four patients (12.9%). The wedge resection technical success rate was 100%. Mean VATS operative time was 167.3 ± 75.2 min, with a mean blood loss of 92.6 ± 61.5 ml. Patients were followed between 3 and 46 months (median: 24 months), with no evidence of new nodules, distant metastases, or postoperative complications in any patients. Conclusion: Preoperative CT-guided multiple coil localization can be easily and safely used to guide single-stage VATS diagnostic wedge resection in patients with MLNs.

Subintimal revascularization is a mainstay of therapy for lower extremity interventions. This stems from the realization that true lumen traversal is not always possible, subintimal revascularization has a high technical success rate, and the subintimal space may confer advantages over a heavily calcified true lumen. Most commonly in the tibial vasculature, there are times when subintimal recanalization is not possible because the wire and catheter may leave the subintimal plane and enter the periadventitial tissue. Although this is not intentional, exit from the vessel historically results in a technical failure because future passes of the wire and catheter are likely to follow suit, as evidenced by extravasation on contrast injection. This chapter describes two techniques to salvage this scenario and accept an extravascular tract for revascularization: the Outback® extravascular revascularization technique and the percutaneous gun-sight extravascular revascularization technique.

Objective. To assess prospectively the first experience of subintimal angioplasty of superficial femoral artery occlusions. Patients and methods. Within a period of 36 months, 45 patients with 45 chronic occlusions in superficial femoral artery were treated at Kaunas University of Medicine Hospital. Results. The technical success rate was 84.4%, and four failures were treated by conventional surgery. The following complications occurred: one hematoma at the arterial puncture site, one artery spasm, and two distal embolizations. The mean length of occlusions was 14.2±1.4 cm. The mean ankle-brachial index improved from 0.41±0.15 to 0.81±0.04 after successful subintimal angioplasty (P<0.001). Primary assisted patency rates were 94.7%, 92.1%, 84.2%, 81.6%, and 81.6% at 1, 3, 6, 12, and 24 months, respectively. The limb salvage rates were 100% and 97.8% at 1–3 and 6–12–24 months, respectively. There were no treatmentrelated amputations. Conclusions. Subintimal angioplasty of occluded superficial femoral artery is a safe and minimally invasive procedure with a high initial technical success rate, low complication rate, and good early results, and in case of failure, subsequent surgery can be performed.

AbstractRecently, antegrade dissection re-entry (ADR) with re-entry device for chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has evolved to become one of the pillar techniques of the hybrid algorithm. Although the success rate of the device is high, it could be improved. We sought to evaluate the current trends and issues associated with ADR in Japan and evaluate the potential of cardiac computed tomography angiography (CCTA) for ADR procedure. A total 48 patients with CTO suitable for ADR evaluated by baseline conventional angiography and CCTA were enrolled. Procedural success and technical success were evaluated as the primary and secondary observations. Furthermore, all puncture points were analyzed by CCTA. CT score at each punctured site depended on the location of plaque deposition (none; + 0, at isolated myocardial site; + 1, at epicardial site; + 2) and the presence of calcification (none; + 0, presence; + 1) was analyzed and calculated (score 0–3). Overall procedure success rate was 95.8%. Thirty-two cases were attempted with the ADR procedure and 25 cases of them were successful. The technical success rate was 78.1% and myocardial infarction or other major complications were not observed in any cases. CT score at 60 puncture sites in 32 cases were analyzed and the score at technical success points was significantly smaller compared to that at technical failure points (0.68 ± 1.09 vs 1.77 ± 1.09, p < 0.0001). CTO-PCI with Stingray device in Japan could achieve a high procedure success and technical success rate. Pre procedure cardiac CT evaluation might support ADR procedure for appropriate patient selection or puncture site selection.

Objectives: To compare the efficacy and safety of preoperative localization of ground glass nodule (GGN) using embolization microcoils and the locating needles designed for pulmonary nodules. Methods: From June 2019 to December 2020, 429 patients who received CT-guided localization of single GGN before video-assisted thoracoscopic surgery (VATS) were enrolled. The diameter and depth of GGNs were 0.84 ± 0.39 cm and 1.66 ± 1.37 cm. Among 429 cases, the first 221 GGNs were marked with microcoils (the microcoil group), and the remaining 208 GGNs were marked with the locating needles designed for pulmonary nodules (the locating needle group). SPSS 17.0 statistical software was used to compare the marking success rate, marking time, marking-related complications between two groups. p values < 0.05 were considered statistically significant. Results: The marking time in the microcoil group was longer than that in the locating needle group (11.1 ± 3.9 vs 8.2 ± 2.0 min, t = −7.87, p = 0.000). The marking success rate in the microcoil group was lower than that in the locating needle group (91.4% vs 98.6%, χ2 = 11.27, p = 0.001). In the microcoil group, marking failures included 16 cases of microcoil dislocation and 3 cases of unsatisfactory microcoil position, while all 3 cases of marking failure in the locating needle group were due to unsatisfactory anchor position. No significant differences in the incidence of total complications (23.1% vs 22.1%), pneumothorax (18.1% vs 19.2%), hemorrhage (9.5% vs 9.1%), and hemoptysis (1.8% vs 1.4%) were observed between the two groups. All the complications were minor and did not need special treatment. Except for one case in the microcoil group, which was converted to thoracotomy, the remaining 428 GGNs were successfully resected by VATS. Conclusions: It is safe and effective to perform preoperative localization of GGN using either embolization microcoil or the locating needle designed for pulmonary nodules. The locating needle is superior to microcoil for marking GGN in terms of procedure time and the success rate. The complication rate of both methods is similar. Advances in knowledge: The locating needle designed for pulmonary nodules has recently been used to mark pulmonary nodule. Its structure can effectively avoid dislocation after localization, and the marking process is simple and quick. Compared with localization using microcoil, it takes less time and has higher success rate to mark GGNs using the locating needle. The complication rate of both methods is similar.
