EXPERIMENTAL TRACHEAL RESECTION AND ANASTOMOSIS IN DOGS

Tracheal resection with end-to-end anastomosis was accepted as an ideal method for correction of many congenital and acquired surgical affections of the trachea. Clinical attempts for tracheal grafting had been plagued by infection, ingrowth of fibrous tissue, migration of the graft and evintial stenosis (GREENBERG, 1960 and HARRINGTON et al., 1962).
End-to-end tracheal anastomosis after small or massive tracheal ring resection was indicated for congenital localized tracheal stenosis, diverticulum, collapse, perforation, rupture, fracture, fistulae, tracheo megally and primary or secondary neoplasms (SCHEBITZ, 1960, SHAFF, 1963, PERELMAN, 1972, GRILLO, 1973, SCOTT, 1978, BEAUMONT, 1982 and BEDFORD, 1982).
The amount of cervical tracheal ring resection stated in the available literature in dogs ranged from 4-23 ring (FERGUSON, et al., 1950 and DLL MAN and BOJRAB, 1981).
Many suture patterns were indicated for end-to-end anastomosis (DEDO, et al., 1969, ORDON, 1973, KOTAKE and GRILLO, 1976 and LAU, et al., 1980). The aim of the present study is to determine the possible amount of tracheal ring resection as well as to select the most suitable pattern for trcheal anastomosis in dogs.
