[Reoperations in primary hyperparathyroidism].

We report on 14 patients suffering from persistent (n = 13) and truly recurrent (n = 1) primary hyperparathyroidism. Reoperations were successful in 13 cases. Cervical reexploration was only required for 5 patients who had previous operations by unexperienced surgeons in other clinics.

Clinical aspects of surgery in primary hyperparathyroidism.

60 patients suffering from primary hyperparathyroidism were operated during the period from 1980 till september 1988. The operation was successful in 55 cases. Most patients had single adenomas of the parathyroid glands.

[Diagnosis of primary hyperparathyroidism by selective determination of parathyroid hormones].

Due to a hypercalcaemia and changeably appearing hypercalciuria 13 patients with relapsing urolithiasis were under suspicion of a primary hyperparathyroidism. After selective sounding and withdrawal of blood from the cervical veins in all cases the determination of parathormones was performed and always an increased activity of parathormones was found. The exploration of the cervical region carried out could in 11 performed operations in 8 cases prove an adenoma and in 3 cases a hyperplasia as cause of hyperparathyroidism.

[Surgical treatment in deep venous thrombosis of the legs and pelvis (author's transl)].

The only effective causal therapy in thromboses of the deep pelvic and femoral veins is fibrinolysis or operative thrombectomy. Concerning the contraindications, fibrinolysis is successful only up to the 5th day. After that time patients with deep vein thrombosis were submitted to thrombectomy and at the same time, to prevent renewed thrombosis secondary to a slowing down of the flow, a peripheral arteriovenous fistula was temporarily positioned.
