Malignancy and viability of intraparenchymal brain tumours: correlation between Gd-DTPA contrast MR images and proliferative potentials.

abstract：BACKGROUND:Distal anterior cerebral artery (DACA) aneurysms represent 2-9 % of intracranial aneurysms. They are often more amenable to surgical rather than endovascular treatment due to the size of parent vessels. METHOD:We illustrate surgical approaches for DACA aneurysms arising from different segments of the anteri...

abstract：:The hypothesis is developed that plateau waves (PW) are caused by an abrupt elevation of postcapillary flow resistance induced by compression of the outlets of the leptomeningeal veins. It is shown by means of a physical model that the main prerequisite for venous outlet compression consists in an elevation of the out...
