Computed tomography-guided patent blue vital dye localization of pulmonary nodules in uniportal thoracoscopy

Abstract

Preoperative CT-guided PBV dye localization is a feasible, safe, and accurate procedure. It makes uniportal VATS easy for small, poorly located pulmonary nodules with GGO predominance and synchronous multiple nodules.

Nonintubated uniportal thoracoscopic wedge resection for early lung cancer

“…In uniportal VATS, it can be difficult for surgeons to determine how deep their staple applied to obtain free section margins, especially when patients present with deep and non-palpable nodules. In previous studies, we have used two 2-0 silk anchoring retraction sutures at the proximal and distal side of the nodule (16,17) to extracorporeally retract and lift up the nodule. This practice not only avoids the long instruments that have been conventionally used for lung parenchyma grasping, but also provides sufficient space within which to achieve an adequate section margin.…”

“…If the tumor is small, located far from the lung surface, or predominantly composed of groundglass component, it is difficult to localize the tumor intraoperatively, especially in a uniportal thoracoscopic setting. Therefore, a preoperative CT-guided patent blue vital (PBV) dye localization technique, the details of which we described elsewhere, was arranged under the consensus of both surgeon and radiologist (16). The dye localization was performed preoperatively by experienced radiologists.…”

Preoperative computed tomography-guided dye injection to localize multiple lung nodules for video-assisted thoracoscopic surgery

“…The CT-guided PBV dye localization procedure has previously been described in detail (13). All of the patients were required to stop taking antiplatelet agents 5 days before the procedure, had a platelet count of more than 80×10 3 /μL, and normal prothrombin and activated partial thromboplastin time.…”

Non-intubated single-incision video-assisted thoracic surgery: a two-center cohort of 188 patients

“…In patients with such lesions, preoperative CT-guided dye localization and intraoperative frozen section were routinely performed to ensure satisfactory oncological treatment (13,14).…”
