[Experience with transluminal stent-assisted angioplasty for intracranial vascular diseases].

Objective: To assess the value of stent-assistant angioplasty for intracranial vascular diseases.

Methods: Thirteen patients with intracranial vascular diseases were treated consecutively by stent-assistant angioplasty for different purposes. Of these patients 7 had symptomatic intracranial artery stenosis, 3 intracranial wide-neck aneurysms, 2 intracranial pseudoaneurysms, and 1 bilateral transverse sinus stenosis.

[Three dimensional digital subtraction angiography in volume embolization ratio measurement of densely packing experimental aneurysms].

Objective: To calculate the volume embolization ratio of densely packing experimental aneurysms by three dimensional digital subtraction angiography (3D-DSA).

Methods: Six experimental crotch aneurysms were created microsurgically in the common carotid artery of white rabbits. Two weeks later, each aneurysm's volume was measured with 3D-DSA surface shaded display(SSD) and the correction of lacteprene balloon calibration method.

[Spinal dural arteriovenous fistulae associated with perimedullary arteriovenous fistulae: imaging characteristics and surgical treatment].

Objective: To enhance the clinical doctors' cognizance of atypical spinal dural arteriovenous fistulae (SDAVFs) associated with perimedullary anteriovenous fistulae (PMAVFs).

Methods: The clinical imaging and surgical therapy of 3 patients with PMAVFs were analyzed retrospectively.

Results: The clinical presentations of the 3 patients were not significantly different from those of typical SDAVFs.
