The incidence of postoperative venous thrombosis and pulmonary embolism was assessed in 87 patients undergoing 96 major lower extremity amputations for ischemia. Prospective surveillance for deep leg vein thrombosis was carried out by Doppler ultrasound in 35 patients. ⋯ This study suggests that clinically significant venous thromboembolism following current techniques of lower extremity amputation is not as common as previously reported. Doppler ultrasound is the most suitable technique for surveillance of venous thrombosis in these patients.

Tracheal stenosis following assisted ventilation is becoming recognized as a major complication of tracheostomy, and the use of cuffed tracheostomy tubes. The possible causes and surgical management of this condition are discussed together with recommendations to minimize the possibility of post-tracheostomy tracheal stenosis.

Angel-closure glaucoma following scleral buckling operations.
We have observed 22 patients with angle-closure glaucoma following scleral buckling operations. These patients did not have narrow anterior chamber angles preoperatively, and several were aphakix with surgical iris colobomas. ⋯ A likely pathogenic mechanism is congestion and swelling of the ciliary body due to a temporary interference by the scleral buckle with venous drainage. Episcleral implants accounted for a statistically significant higher incidence of angle-closure glaucoma as compared to intrascleral implants.

Additional operations were necessary in 67 (41%) of 162 renal allograft patients. General anesthesia was employed in all but 5 patients with no morbidity or mortality. All patients were immunosuppressed and no additional steroids were used before, during, or after the procedure. ⋯ Nine patients (6%) required operations unrelated to transplantation. The data indicate that transplant patients frequently need additional procedures which are directly related to the transplant operation, immunosuppression, or metabolic alterations of their past uremic condition. Mortality is related to the degree of toxicity from the immunosuppressive therapy.
