The disappearing hook wire: a case report.

ABSTRACT:

Background

The migration of hook wire used for lung nodule localization to the pulmonary artery is an extremely rare complication. We report a case of migration of hook wire used for lung nodule localization to the main pulmonary artery and discuss the management.

Case description

The patient was a 50-year-old female with multiple pulmonary nodules, the largest of which was 7 mm and located in right lower lob. Since the size of the nodules were very small, three computed tomography (CT)-guided percutaneous hook wires were placed to localize the nodules prior to surgery. After entering the thorax, the wires were unable to be located in the right lower lobe and an intraoperative urgent chest CT demonstrated that the markers had migrated to the pulmonary artery. Therefore, the original surgical incision was extended and the superior tip subsegment of the pulmonary artery of the right lung was dissected open and the positioning needle was successfully removed. The patient was recovered without further complication and discharged 5 days later.

Conclusions

When the exact location of a hook wire utilized for lung nodule localization cannot be determined, an exhaustive radiographic evaluation is required to determine the wire's specific location. If conditions permit, it is best to remove the hook wire directly using video-assisted thoracoscopic surgery (VATS). With careful perioperative assessment, surgeons can avoid additional complications and further surgery if they encounter a migrated nodule localization wire.
