Management of isolated non-traumatic renal artery dissection: report of four cases.

Background: Isolated non-traumatic renal artery dissection (RAD) is a rare disorder with uncertain natural history. The management may be surgical reconstruction, endovascular repair, or conservative medical treatment, yet no official consensus had been established.

Purpose: To report the management of four cases of isolated non-traumatic RAD, emphasizing the beneficial role of conservative medical treatment.

Endovascular treatment of eight renal artery aneurysms.

Background: Renal artery aneurysms (RAA) are a relatively rare vascular entity. Treatment could be either surgical or via an endovascular route. The main aim of therapy is to prevent lethal rupture.

Endovascular coil occlusion of 152 middle cerebral artery aneurysms: initial and midterm angiographic and clinical results.

Object: The object of this study was to evaluate the initial and mid-term angiographic and clinical results after endovascular coil occlusion of middle cerebral artery (MCA) aneurysms at the authors' institution.

Methods: The authors conducted a retrospective analysis of a consecutive series of 152 MCA aneurysms (73 ruptured) treated by endovascular coiling in 140 patients. Angiographic and clinical data at initial and midterm follow-up as well as procedure-related complications were prospectively registered.

Balloon-assisted embolization of skull base meningioma with liquid embolic agent.

The authors report a novel technique of balloon-assisted embolization of a skull base meningioma supplied by a branch of the cavernous segment of the internal carotid artery using liquid embolic agent. A temporarily inflated balloon distal to the meningioma's feeding vessel may improve the access to this small branch and may reduce the chances of unintended reflux during delivery of the liquid embolic agent.
