Preoperative Computed Tomography-Guided Pulmonary Lesion Marking in Preparation for Fluoroscopic Wedge Resection-Rates of Success, Complications, and Pathology Outcomes.

PURPOSE: In this study, we describe our experience of lesion marking with fiducial markers (FM) and microcoils (MC) facilitating same-day surgical wedge resection, including success rates, pathology outcomes, and complications. We also explored patient/nodular characteristics associated with developing complications.

MATERIALS AND

METHODS

An IRB-approved single-institutional retrospective study of 136 patients who had 148 pulmonary nodules was conducted. All patients had CT-guided pulmonary nodule labeling with either FM (121) or MC (15) patients with plan for same-day fluoroscopic-guided wedge resection.

RESULTS

Of 136 (98%) patients, 133 had successful same-day wedge resection as planned; 2 had delayed but successful wedge resection surgery due to complications at the time of marker placement (fiducial embolization and hemorrhage/pneumothorax, respectively). A third patient ultimately needed lobectomy due to deep lesion location. Eighty percent [118/148] of resected nodules were malignant. Further, 68% of the total group of patients [93/136] had mild complications of various types including hemorrhage [44/136, 32%], pneumothorax [35/136, 26%], a combination of both hemorrhage and pneumothorax [10/136, 7%], or migration/embolization [4/136, 3%]. Depth of nodule from skin (P = 0.011) and pleura (P = 0.027) was significantly associated with complications.

CONCLUSION

CT-guided marking of small or deep pulmonary lesions using either fiducial markers or microcoils provides an effective means to aid surgeons to accomplish minimally invasive wedge resection. The importance of the success of this technique is supported by the high incidence (80%) of malignant lesion etiology found at postresection pathology. Although complications occurred, the vast majority were mild and did not alter planned same-day resection.
