SPECIFICATIONS OF INTRACRANIAL SACCULAR ANEURYSMS, TREATED BY ENDOVASCULAR APPROACH USING DETACHABLE COILS.

The treatment of intracranial saccular aneurysms remains an actual problem due to this pathology prevalence among the human population (about 1-10%). For definition of efficiency and preventive importance of endovascular treatment, it is necessary to clear define which aneurysms are more suitable and operable for endovascular occlusion with minimal risk of complications and better final outcome. The aim of this study is to analyze anatomical features (location and structure) of intracranial saccular aneurysms and clinical data of patients who have been operated endovascular, with detachable coils in High Technology Medical Center University Clinic,Tbilisi, Georgia for the last 6 years.

VPF and interstitial fluid pressure in brain oedema.

Monitoring of VFP and local brain interstitial fluid pressure was performed in 169 patients after removal of hemispheric gliomas, basal and subtentorial tumours. On the basis of CT-data 97% of the patients had postoperative oedema of various severity and spreading. The location of the tumour determined both the degree and severity of oedema as well as VFP and ISFP.

[Postoperative edema in brain tumors].

CT examination of postoperative edema of the brain in 251 neurosurgical patients showed edema to be determined by the location and histostructure of the tumor. The data obtained suggested that the pathogenesis of edema differs. Thus, vasogenous edema develops predominantly after removal of hemispheric gliomas, cytotoxic (hypoxic) edema--after removal of basal-diencephalic tumors, and hydrostatic edema--after removal of subtentorial tumors.
