[Surgical correction of post-vertebroplasty kyphosis by pedicle substraction osteotomy. Regarding three cases].

We report a case of three patients treated with pedicle subtraction osteotomy for post-vertebroplasty kyphosis. These patients were initially treated with a vertebroplasty for vertebral fracture (two cases) and spinal lymphoma (1 case). All of these patients worsened progressively on a clinical and radiographic level with progression of the spinal deformity in the form of kyphosis.

[Surgical treatment of stenosis-thrombosis of internal carotids by extra-intracranial arterial anastomosis and endarterectomy].

The surgery of the remaining carotid artery is a very difficult procedure considering the high risk related to the peroperative clamping. Extracranial to intracranial by pass of the thrombosed side permit to carry out in better conditions the contralateral endarterectomy without using intravascular shunt.

[Evaluation of the clinical benefit of decompression hemicraniectomy in intracranial hypertension not controlled by medical treatment].

Through the findings in the literature on the basis of 9 personal cases, we review the indications and value of decompressive hemicraniectomy with plasty of the dura mater in cases of medically uncontrolled and decompensated intracranial hypertension. Seven patients had a pseudo-tumoral brain infarction. Five patients survived and their functional recovery is consistent with an autonomous daily life.

[Idiopathic giant cell granulomas of the pituitary gland. Apropos of 2 cases].

Two cases are reported of two women who had developed progressive hypopituitarism without visual disturbances. Pituitary tumors were evoked by radiological findings. The patients underwent surgical removal of invasive intrasellar tumor by transphenoidal route.
