Comparative Study[Lung resection surgery in patients with functional limits].
To determine whether there exists in our area concordance between forced expiratory volume in one second (FEV1) estimated before surgery by ventilation/perfusion scintigraphy and real values after surgery in patients undergoing pneumonectomy and lobectomy. Prospective descriptive study. We studied 15 patients undergoing pneumonectomy (M/F 14:1, age 62 +/- 7.5 years) and 11 undergoing lobectomy (M/F 11:0 age 66 +/- 3.5 years) in the thoracic surgery unit of Hospital de Cruces between 1 March 1990 and 1 March 1993. ⋯ Correlation was statistically insignificant in lobectomy patients (0.28 by the method of Ali and 0.35 by Wernly's; p = 0.19 and 0.13, respectively). Ventilation scintigraphy offers an acceptably reliable prediction of FEV1 after lung resection. The reliability of measurements estimated by scintigraphy in lobectomized patients is not acceptable.
