[Perfusion scintigraphy and surgical excision of bronchial cancers].

In a series of 1,800 operated lung cancers, 93 had a unilateral perfusion scan less than or equal to 20% (36 perfusions = 0, 15 between one and 10% and 42 between 11 and 20%). Major amputations were more frequent on the left side and constituted a pejorative but non-decisive factor for surgical nonintervention although was not synonymous with inoperability. The extent of the resection increased with the severity of the amputation.
