dc.description.abstractBACKGROUND: Intraoperative pulmonary artery (PA) hemorrhage is one of the leading reasons for conversion from uniportal VATS to open thoracotomy, especially for the small incision (≤3 cm) uniportal VATS performed by our department. So, We designed a technology called pretreatment clamping of the pulmonary artery, which may be helpful to solve the problem. METHODS: A retrospective analysis of 19 patients who had pulmonary artery bleeding during uniportal thoracoscopic lobectomy in which one group had undergone preventive pulmonary artery clamping, the clamping group (n = 11), and one group which did not receive preventive clamping, the non-clamping group (n = 8). We compared the rates of conversion from the uniportal VATS approach to open thoracotomy or multi-incision operation, duration of pulmonary artery repair, blood loss, length of postoperative hospital stay and postoperative complications of the two groups. RESULTS: Compared to the non-clamping group, the clamping group had lower rates of conversion to open thoracotomy (0% vs 62.5%, p < 0.05) and lower rates of conversion to multi-incision operations (18.2% of non-clamping converted to 2-port approach vs 12.5% of clamping converted to 2-port approach and 12.5% converted to 3-port approach, p < 0.05). Duration of pulmonary artery repair was reduced in the clamping group (10.1 ± 3.2 min vs 18.3 ± 5.5 min, p < 0.05). The clamping group also had decreased blood loss (23.6 ± 11.2 ml vs 47.5 ± 14.9 ml, p<0.05). There were no significant differences in postoperative hospital stay and postoperative complications between the two groups. CONCLUSION: Pretreatment clamping of the pulmonary artery in VATS lobectomy can decrease conversion rates, decrease blood loss, shorten repairing time of the pulmonary artery, and feasibly can be applied in uniportal thoracoscopic lobectomy.en_US
