Prosthetic tracheal replacement.

Prosthetic valve replacement.

1 find it somewhat surprising that after twcnty years of valve replacement the subject is stiii a topic for discussion at major cardiac surgical meetings. This undoubt ediy reflects the status of valves today since there stili rernains no ideal vaive substitute.

Tracheal replacement by autogenous aorta

BACKGROUND Tracheal defects may occur after trauma or prolonged intubation. Resection of tracheal tumors also poses a major challenge for substitution. In an effort to solve this problem, different techniques have been tried with little success. We report on a new animal model which showed acceptable results with fewer complications. METHODS We replaced 5 cm of cervical trachea in 10 dogs wit...

Total prosthetic replacement of the temporomandibular joint.

Twenty-seven patients have been operated on for total replacement of the temporomandibular joint because of ankylosis due to trauma, arthritis, neoplasm, infection, or pain. One prosthesis had to be taken out because of gross infection due to Staphylococcus albus, 2 more were removed for pain and dislocation of the prosthesis, and 1 was removed because of erosion through the skin. The remaining...

Cardioversion following prosthetic mitral valve replacement.

SUMMARY Direct current conversion of atrial fibrillation has been attempted in 60 consecutive patients following prosthetic mitral valve replacement (Starr-Edwards prosthesis). Sinus rhythm was attained and persisted for at least 24 hours after the procedure in 68% (41 patients) and 40% of the entire group (24 patients) were still in normal sinus rhythm an average of 10 months later. Successful...
