Ε. Ανδριώτης και συν. Διαδερμικός εντοπισμός οζιδίων του πνεύμονα με συρμάτινα άγκιστρα πριν από θωρακοσκοπική εκτομή
Patients And Methods:
12 patients with suspicious
subpleural pulmonary nodules underwent preoperative
CT-guided hook wire localization of the lesions, prior
to video assisted thoracoscopic surgery (VATS). Τhe
diameter of the lesions ranged from 1 to 3cm and their
distance from the nearest pleural surface ranged from 3
to 5cm. Various hook wires, regarding the shape of the
hook were used in each patient. After the localization,
all patients were transferred to the operating room, so
that a video-assisted thoracoscopic surgery could be
performed.
Results:
The placement of the hook was successful
in all patients. The mean time needed to position the
hook was 10min. No major complications were expe-
rienced. Histological analysis of the resected suspicious
pulmonary nodules revealed malignancy in 10 cases,
1 case with granuloma and 1 case with bronchiolitis
obliterans organizing pneumonia (BOOP). Better re-
sults were achieved with the double-thorn hook wire
and when the hook was placed near the lesion and not
through it. Thoracotomy conversion was necessary in
the patient with BOOP, due to limited hemorrhage at
the site of the lesion.
Conclusion:
Preoperative CT guided nodule localization
using hook wire fixation is a useful and safe technique
that helps in the precise localization of suspicious le-
sions, reduces the operation time, the postoperative
complications, and the hospitalization.
