MONDAY, Feb. 2 (HealthDay News) -- Computed tomography-guided placement of microcoils to guide video-assisted thoracoscopic surgical (VATS) excision of lung nodules is safe and effective with few complications, according to study findings published in the February issue of Radiology.
John R. Mayo, M.D., and colleagues from Vancouver General Hospital in British Columbia, Canada, examined the safety and effectiveness of using computed tomography to guide the placement of fiber-coated microcoils used to guide VATS excision of small peripheral lung nodules in 69 patients with 75 nodules.
The researchers removed 97 percent of nodules (4 to 24 mm in size) successfully. Microcoil placement was successful in all cases, although 3 percent of coils were displaced during VATS excision. In 3 percent of patients, pneumothorax requiring chest tube placement occurred and in 1 percent of patients asymptomatic hemothorax occurred, the report indicates. The microcoil did not interfere with intraoperative frozen-section histopathologic analysis, and the pre-operative management plan changed in 28 percent of patients after VATS excision, the authors note.
"The use of this technique may help to address the diagnostic dilemma of increasing numbers of small peripheral lung nodules that are detected incidentally or found at serial chest computed tomography to be growing," Mayo and colleagues conclude.
