Graded pressure stockings in prevention of deep vein thrombosis following total hip replacement.

The occurrence and distribution of deep vein thrombosis after elective hip surgery were studied in 22 consecutive patients wearing graded pressure stockings as thromboprophylaxis. The frequency of thrombosis, as evidenced by leg-scan and phlebography, was 59%. Thirty-six per cent of the patients developed femoro-popliteal thrombosis.

A clinical and phlebographic study of postoperative deep vein thrombosis following knee meniscus extirpation.

To evaluate the risk of deep vein thrombosis, a clinical and phlebographic examination was performed 7 to 16 days after a bloodless knee meniscus operation in 37 male patients aged 20 to 35 years. Anticoagulant prophylaxis was not administered. Phlebography revealed asymptomatic calf vein thrombosis in three patients and these were not treated.

Tracheo-oesophageal fistula caused by cuffed tracheal tubes.

Two patients with tracheo-oesophageal fistula following endotracheal intubation and tracheostomy are reported. In both cases the fistulas were related to inflammation of the cuffs distal to the tracheostomy. Two kinds of surgical treatment were performed: (1) Resection of 3 cm of the cervical trachea, closure of the oesophageal fistula opening with absorbable sutures and interposing a muscle flap of the left sternohyoid muscle.
