ABSTRACT
OBJECTIVES:
To demonstrate the usefulness of intrapericardial inspection of pulmonary vessels by video assisted thoracoscopy (VAT), for determining whether suspicion indicated by computed axial tomography (CAT) or magnetic resonance (MR) scanning is justified or not. PATIENTS ANDMETHOD:
Since 1993 we have used exploratory VAT for final staging and assessment of lung cancer resectability. Intrapericardial vascular exploration (IVE) is a complementary method of assessing resectability in cT4 cases. We have performed 20 IVE among 460 VAT when intrapericardial involvement of pulmonary vessels has been suspected (19 men, 1 woman, mean age 64.6 years, range 50-77). VAT demonstrated invasion for 11 patients with previous suspicion based on hilar and vascular invasion shown by CAT scan; in 9 others such involvement was found during IVE for assessing resectability. VAT-IVE was performed through three or sometimes four entrance approaches, from which intrapericardial vessels were explored easily.RESULTS:
Five cases were non-resectable four due to invasion of the pulmonary artery to its point of origin and one due to extensive invasion of pulmonary veins and the left auricle. The remaining 15 cases were resectable and lesions were removed by posterolateral thoracotomy with intrapericardial dissection and ligature of the vessels. Five had been considered non-resectable by teams at other hospitals where they were classified as advanced cT4 cancers after imaging. The mean duration of IVE was 23 minutes (range 16 to 33); mean postprocedural stay was 48 h in non-resected patients, who were sent for neoadjuvant therapy on the third day. These patients, who underwent only IVE, had no complications and there were no deaths, with five unnecessary thoracotomies avoided.CONCLUSIONS:
IVE allows correct staging of the T parameter in patients for whom T4 classification is suspected, avoiding unnecessary thoracotomies in non-resectable cases and allowing for surgical removal in cases where CAT or MR imaging results are unclear.
