Successful renal revascularization of unilateral traumatic renal artery thrombosis.

We report 3 patients with traumatic renal artery thrombosis treated successfully with revascularization. The diagnosis was made preoperatively in 2 cases and intraoperatively in 1. Treatment consisted of reanastomosis with a saphenous vein patch on the side of the arteriotomy in case 1, an aortorenal artery saphenous vein bypass in case 2 and a bypass graft from the aorta to the distal renal artery in case 3.

Cryolesions of bone. An experimental study. part II: Results of cryosurgery on bone.

After freezing-devitalisation of rabbit tibia bone, a slow resorption and substitution by new bone within a period of 6 months could be demonstrated. Intramedullary freezing combined with internal fixation of an osteotomy in the frozen area was followed by a delayed healing. Angiographic studies showed an almost normal circulation after freezing of the main vessels.

[Active and passive vascular involvement in tumours and tumour-like processes in the extremities (author's transl)].

Angiography for tumours of the extremities may demonstrate active or passive involvement of vessels by the tumour. This technique has been used for a considerable time for the diagnosis and differentiation of bone tumours. Angiography is particularly suitable for distinguishing between benign and malignant tumours of soft tissues.
