✓ The authors report two cases of spontaneous carotid-cavernous fistula that occurred during pregnancy. One patient was a 21-year-old woman whose symptoms improved and in whom disappearance of the carotid-cavernous fistula was confirmed by cerebral angiography after she aborted in the 12th week of pregnancy. The other patient was a 25-year-old woman in whom a carotid-cavernous fistula occurred at about the 28th week of pregnancy. The symptoms became aggravated 3 weeks after a normal delivery. Carotid-cavernous fistula was confirmed by cerebral angiography, and the clinical symptoms then improved. On the basis of cerebral angiographic findings, both patients were considered to have dural arteriovenous fistulas in the region of the cavernous sinus and both demonstrated spontaneous improvement.

Angiographic Findings

✓ In patients with intracranial dural arteriovenous fistulas (AVFs), clinical symptoms and angiographic findings vary. The relevance of disturbed venous drainage to clinical symptoms and prognosis has been recognized. However, the roles of cerebral hemodynamics and metabolism, which are impaired by shunt flow or disturbed venous drainage, have not been fully evaluated. The authors studied the cerebral hemodynamic and metabolic status in 10 patients with intracranial dural AVFs using positron emission tomography (PET) scanning. Ten patients with dural AVFs underwent a PET study before treatment. The regional cerebral blood flow (rCBF), regional oxygen extraction fraction (rOEF), regional cerebral metabolic rate of oxygen (rCMRO2), and regional cerebral blood volume (rCBV) were measured using the 15O-labeled gas inhalation steady-state method. The PET parameters that were obtained were analyzed and compared with the patients' neurological and angiographic findings. In six of the 10 patients, a PET study was also performed after treatment. Before treatments, all four patients with cerebral symptoms showed a severe reduction in rCBF and a mild elevation in the rOEF. The areas showing reduced rCBF corresponded with areas in which retrograde venous drainage into the cortical veins and delayed parenchymal circulation were seen on angiograms. In another two patients with occlusion of the affected sinus and/or retrograde drainage into the cortical veins, mild abnormalities were demonstrated in rCBF mapping. In the remaining four patients, all PET parameters except rCBV were within normal limits and venous flow was not impaired on the angiograms. In four patients who underwent surgical excision or transvenous embolization of the affected sinus, the cerebral hemodynamics and metabolism were improved, as were the clinical symptoms. In two patients who underwent transarterial embolization of the feeding vessels only or craniotomy, no hemodynamic improvement was achieved. Our results indicate that hemodynamic insufficiency detected by the PET study corresponded well with cerebral symptoms and angiographic findings of retrograde venous drainage into the cortical veins and delayed parenchymal circulation, but not with sinus occlusion or arterial blood supply. Eradication or prevention of retrograde venous drainage from the affected sinus into the cortical veins should be a treatment goal in patients with dural AVFs.

✓ Spontaneous intracerebral hematoma associated with carotid-cavernous fistula is rare. Three new cases are presented. In each, the hemorrhage originated in the vicinity of localized intracranial venous engorgement, as demonstrated by cerebral angiography. Rupture of one or several of the distended venous channels from increased back-flow is postulated as the etiology of the intraparenchymal hematomas.

Partial Thrombosis

✓ In most cases, intracerebral hemorrhage during pregnancy or puerperium results from cerebral aneurysms or arteriovenous malformations. The authors present a case of a 30-year-old woman whose symptoms from a traumatic carotid-cavernous fistula had completely resolved 1½ years after the event, but recurred 4 years later, causing two hemorrhages during pregnancy (33rd and 35th week of gestation) and one during the postpartum period (10 days after Caesarean section). Partial thrombosis of the cavernous sinus with obliteration of most of the drainage from the fistula accounted for the resolution of clinical symptoms, but also promoted back-flow to the preserved drainage of superficial cortical veins. The hemodynamic changes and the hormonal effects due to the patient's subsequent pregnancy further aggravated the venous engorgement and finally caused rupture. All three hematomas occurred in the vicinity of the extremely dilated veins, suggesting that back-flow with venous hypertension was the probable cause for the intracerebral hematomas. Spontaneous healing of the carotid-cavernous fistula should be confirmed with cerebral angiography.

✓ The author describes a technique for directly closing a carotid cavernous fistula with electrothrombosis while preserving the intracranial arterial circulation. Copper wires are introduced through the superior ophthalmic vein or a frontotemporal craniotomy, and thus directly into the portion of the sinus into which the fistula drains; if posterior, into the posterior segment of Parkinson's triangle, if inferior, into the pterygoid plexus, and if anterior, through the sphenoparietal sinus and/or middle cerebral vein to the anterior-inferior portion of the sinus. A direct current is applied until a thrombus is confirmed angiographically and the wires are left in place. Four patients treated by this method are presented.

Transvenous Approach

✓ An attempt at transfemoral transarterial balloon occlusion of a high-flow spontaneous carotid-cavernous fistula was unsuccessful because the carotid artery rent was too small for this approach. During a subsequent transvenous approach to the cavernous sinus through the jugular vein, the inferior petrosal sinus was perforated. A minor subarachnoid hemorrhage occurred before the tear could be sealed by the deposition of three Gianturco coils in the vein. The patient was taken to the operating room for emergency obliteration of the fistula and petrosal sinus in order to remove the risk of further hemorrhage. Under the guidance of intraoperative digital subtraction angiography, isobutyl-2-cyanoacrylate was injected directly into the surgically exposed cavernous sinus. Successful obliteration of the fistula was achieved with preservation of the carotid artery, and the angiography catheter was removed safely from the petrosal sinus. Although initially after surgery the patient had nearly complete ophthalmoplegia, at her 1-year follow-up examination she had normal ocular motility and visual acuity. The transvenous approach to the cavernous sinus and alternative methods of treatment of carotid-cavernous fistulas are discussed.

✓ The results of 61 cases of stereotaxic thrombosis of intracranial berry aneurysms indicate that the technique in selected cases is comparable to, but not necessarily superior to standard surgical methods. The results of wire-induced thrombosis in 15 cases of giant intracranial aneurysm suggest that this method is effective in situations where clipping and encapsulation are inapplicable. The results of thrombosis in six cases of carotid cavernous fistula suggest that intracavernous wire thrombosis may prove to be the treatment of choice in that it seals the fistula without impairing carotid blood flow.

✓ A carotid-cavernous fistula was occluded by a detachable latex balloon. Because of technical problems, the contrast-filled balloon was left in a precarious position in the ostium of the fistula. Premature deflation of the balloon would have resulted in intra-arterial migration of the device. Approximately 1 week is required for the balloon to become secured in place by fibrous attachment to the vascular wall. For success, if the ligature is adequate, a detachable Debrun balloon should remain inflated for this period of time. The deflation process was monitored radiographically in this patient. The balloon remained inflated for at least 2 weeks. A short summary of the experience with deflation of various contrast-containing balloon devices in the treatment of carotid-cavernous fistulas is given. Metrizamide may be the best contrast agent for use in these devices.

Spinal Dural Arteriovenous Fistulas

Spinal dural arteriovenous fistulas (AVFs), the most common type of spinal cord vascular malformation, can be a challenge to diagnose and treat promptly. The disorder is rare, and the presenting clinical symptoms and signs are nonspecific and insidious at onset. Spinal dural AVFs preferentially affect middle-aged men, and patients most commonly present with gait abnormality or lower-extremity weakness and sensory disturbances. Symptoms gradually progress or decline in a stepwise manner and are commonly associated with pain and sphincter disturbances. Surgical or endovascular disconnection of the fistula has a high success rate with a low rate of morbidity. Motor symptoms are most likely to improve after treatment, followed by sensory disturbances, and lastly sphincter disturbances. Patients with severe neurological deficits at presentation tend to have worse posttreatment functional outcomes than those with mild or moderate pretreatment disability. However, improvement or stabilization of symptoms is seen in the vast majority of treated patients, and thus treatment is justified even in patients with substantial neurological deficits. The extent of intramedullary spinal cord T2 signal abnormality does not correlate with outcomes and should not be used as a prognostic factor.
