RT Journal Article SR Electronic T1 Massive pulmonary gangrene: a severe complication of Klebsiella pneumonia JF Canadian Medical Association Journal JO CMAJ FD Canadian Medical Association SP 196 OP 198 VO 112 IS 2 A1 Knight, L. A1 Fraser, R. G. A1 Robson, H. G. YR 1975 UL http://www.cmaj.ca/content/112/2/196.abstract AB Summary: Massive pulmonary gangrene developed in two patients. Review of the literature reveals 10 other case reports of pulmonary gangrene complicating lobar pneumonia. Among the total of 12 patients whose cases have now been reported, all 4 patients who were treated nonsurgically died and the 8 who underwent surgical resection of the gangrenous lung survived. The present report emphasizes the necessity of early recognition and appropriate surgical treatment for a successful outcome.
