P98 Purpose: Thrombo-embolic complications associated with the endovascular treatment of intracranial aneurysms with Guglielmi Detachable Coils (GDC) generally occur at the time of the procedure or soon after. The purpose of this report is to determine the frequency of late thrombo-embolic events after GDC. Methods: The records of 189 patients who underwent GDC repair of one or more intracranial aneurysms at our institution were reviewed. The occurence of an ischemic event referrable to a coiled aneurysm was determined by clinical, angiographic, and imaging data. Events occuring within 2 days of the endovascular procedure were considered peri-procedural. Kaplan-Meier analysis of ischemic events over time was performed. Results: Two patients suffered documented thrombo-embolic events. One patient presented 5 weeks after coiling with a transient ischemic attack. Angiography demonstrated thrombus on the surface of the coils at the neck of a large ophthalmic artery aneurysm. The second patient presented with a posterior circulation stroke 4 weeks after coiling of a large superior cerebellar artery aneurysm. Angiography showed no significant proximal disease, with thrombus beginning at the neck of the treated aneurysm and extending out both P1 segments. No intra-procedural problems during the initial coiling had occured with either patient. There was no evidence for protrusion of coils into the parent artery in either patient. Both patients had been receiving daily aspirin (325 mg). One additional patient reporting symptoms suggesting possible ischemics event was evaluated and diagnosed as having atypical migraines. The frequency of a clinical thromboembolic event during the first year after coiling (excluding procedural complications) was 1.1%. Conclusions: Thrombo-embolic events may occur as late as 5 weeks after endovascular treatment of aneurysms with GDC.

Orbital Varix

A case of orbital varix is presented, in which the lesion was successfully treated by means of embolisation with Guglielmi detachable coils, via the superficial temporal vein. Reports of endovascular treatment via transvenous route of orbital varix are lacking, only one case having previously been presented in the literature. We stress endovascular management for such an entity.

Thirteen cases of cerebral aneurysms submitted to endovascular treatment using Guglielmi detachable coils (GDC) are described. Control MRI-angiography 3D TOF was performed three and six months later. In order to spare patients the discomfort and risks related to repeated trauma and iodate contrast injection, we examined the possibility of an alternative non-invasive diagnostic method. For this purpose, the digital subtraction angiograms performed three and six months after embolisation were compared with the MR-angiograms obtained in the same period, all using the same tomograph at middle field intensity (0.5T). We discuss the outcome of this comparison and the limits of the MR-angiography method in the follow-up of aneurysms submitted to endovascular treatment.

Arteriovenous Fistulas

We present diagnostic problems, strategies, techniques and material selection for endovascular treatment of high flow arteriovenous fistula (AVF) of tortuous and fragile vertebral artery (VA) with neurofibromatosis type 1 (NF1). Diagnosis of NF1 was easy in four of our cases because of neurofibromatosis, skin pigmentation and various skeletal abnormalities. These stigmas of NF1 were lacking in one case, and the only clue to the diagnosis was ovoid bone defects of the skull vault. Diagnosis was made by performing biopsy of scalp neurofibromas incidentally found on CT. In two initial cases, venous varix were packed with coils by transvenous approach after the transarterial embolisation failed to completely cure the fistula. In three recent cases, blood flow through the fistula was markedly reduced as an initial step by placing detachable coils into the distal and proximal stumps of the afferent VA. Then a liquid adhesive was injected under systemic hypotension to completely occlude the fistula. Control angiography revealed that the AVFs were completely occluded in all cases. Long-term angiographical and clinical status have been stable in all cases. Trying to attain complete occlusion of fistulas using detachable balloons is not an appropriate treatment option for high flow fistulas situated on markedly dilated, tortuous and fragile VAs of patients with NF1. Also, trapping of fistulas is not justified because of the numerous potential feeding pedicles, and makes the following procedure difficult.
