Bilateral carotid-cavernous fistula are much less frequent and these double lesions are considered as a puzzling therapeutic problem. A case of bilateral traumatic carotid-cavernous fistula was confirmed by bilateral carotid angiography and was managed by method of muscle piece embolization without complications. Neuro-ophthalmological deficits improved progressively except minor bruit. We reviewed bilateral carotid-cavernous fistula in the literatures and discussed the surgical method.

A study on 16 rabbits (9 normal rabbits and 7 rabbits with the vascularization by microsurgery) aimed to evaluate the arterial fistula after experimental microsurgery has shown that although there were a little number of checked fistula (11 arteries), the blood circulation of all fistula were evaluated precisely. The study concluded that the digital angiography was considered as a good method of evaluation of the fistula in experimental rabbit.

Diagnostic radiologic studies for angiosarcoma are usually non-specific, but selective angiography is notablyexceptional, and there had been a few reports of CT or US featurs of hepatic or splenic angiosarcoma. We recentlyexperienced a case of hepatic and splenic angiosarcoma demonstrated by CT, US and selective angiogram in34-year0old man.

Intra-Arterial Digital Subtraction Angiography(IADSA) was performed in 128 patients during 13-month period. Weexperienced the same advantages of IADSA over conventional film-screen angiography:(1) significant reduction incontrast material dose: 1/3 of the dose of conventional angiography, (2) reduced film cost: 18% of the cost ofconventional technique, (3) decreased need for selective catherization,(4) shortened examination time, and (5)more ready detection of cnntrast material.

PURPOSE: The purpose of this study was to assess the relative diagnostic capability of magnetic resonance angiography(MRA) and CT angiography(CTA) in the evaluation of intracranial aneurysm. MATERIALS AND METHODS: MRA and CTA were performed in 14 intracranial aneurysms (Including four which were ruptured) confirmed in the II patients involved by conventional angiography(CA). The size(in largest dimension) of the aneurysms ranged between 3 mm and 20 mm and the mean was 10.5 mm. For MRA, the 3D TOF method, with magnetization transfer suppression, wasused at 1.5T. For CTA, twenty seconds after beginning the injection of contrast media(100mL with use of a power injector at the rate of 3 mL/sec), CT scanning(30-second exposure and 60-mm length) was performed with a table speed of 2 mm/sec and a section thickness of 2mm. The resulting data were reformatted by MIP. MRA and CTA were compared with regard to the detection of aneurysms and their neck, size, shape, direction, intensity and relationship to adjacent bony structures or vessels. RESULTS: All aneurysms were clearly visualized with CTA. Inone case with a 3-mm aneurysm, however, this was not defined on MRA. Of the 13 aneurysms demonstrated by both MRA and CTA, eight were seen equally well with both modalities. CTA was considered to be superior to MRA in fivecases, either because calcification in the aneurysm wall was seen only on CTA(n = 3) or because the relationship with adjacent bony structures were seen better with CTA(n = 2). With CTA, the intensities of the aneurysm were homogeneous in all cases ; with MRA, however, the intensities of three large aneurysms were different. CONCLUSION: MRA and CTA may be useful in the evaluation of intracranial aneurysm, CTA has specific advantages over MRA inthe evaluation of large aneurysms, calcification of aneurysm wall and relationship with adjacent bony structure.

We report the imaging features of four cases with calcified intracranial aneurysm. All four patients underwentCT, CT angiography, MR, magnetic resonance angiography, and angiography. Calcification of the aneurysm wall was clearly demonstrated with CT and CTA in all cases and with conventional angiography in one case. The shape of calcification was curvilinear in two cases and punctate in two. On MR, two curvilinear calcifications were demonstrated as peripheral rim of signal void but two punctate calcifications were not shown.
