Lung function and perfusion after bronchial and pulmonary arterial sleeve resection.
Between January 1985 and December 1991, six patients underwent arterial and bronchial sleeve resections of the left upper lobe. Preoperative and postoperative spirometry, preoperative split pulmonary radionuclide ventilation/perfusion (V/Q) scans and postoperative bronchoscopy were obtained in four patients. Postoperative serial digital vascular images (DVI) of the pulmonary artery were obtained in three patients and one patient had a postoperative V/Q scan. For each patient the preoperative and postoperative forced expiratory volume in is (FEV1) were determined to assess the postoperative ventilatory recovery. At bronchoscopy all patients had a patent bronchial anastomosis. At postoperative DVI, in three patients, vascularization of the residual left lung was delayed and less intense compared with the non-operated right lung. Postoperative V/Q scan, in one patient, showed reduced ventilation and perfusion of the residual lung. Preoperative and postoperative FEV1 of the four patients were 2688/1998 ml, 2154/1752 ml, 2618/2100 ml and 2277/2015 ml. Operative mortality was zero. One patient had a postoperative atelectasis of the left lower lobe. In our series, ventilation and vascularization of the reimplanted and revascularized left lower lobe were reduced. But, in our opinion, the preserved residual lung parenchyma was still a relevant advantage.
