✓ In a series of 1107 patients with cerebrovascular disease studied by four-vessel angiography, the authors have found 10 cases of a bypass anomaly of the vertebral artery. Six of the cases also had cerebral aneurysms, and two cerebral arteriovenous malformations. The authors discuss the possible origins for this relationship.

✓ Wyburn-Mason syndrome is a rare condition associated with multiple cerebral arteriovenous malformations. The disease, also called retinoencephalofacial angiomatosis, includes lesions of the retina, brain, and skin. This disorder stems from a vascular dysgenesis of the embryological anterior plexus early in the gestational period when the primitive vascular mesoderm is shared by the involved structures. The timing of the insult to the embryonic tissue determines which structures are affected. Extensions of the lesions vary widely but cutaneous lesions are unusual. Among reports in the literature, only three cases appear to have manifested without retinal involvement. The authors report the fourth case of Wyburn-Mason syndrome in which there was no retinal involvement and the first to involve neither the retina nor the face.

✓ A patient presented with spontaneous subarachnoid hemorrhage (SAH) from a cerebral arteriovenous malformation (AVM) which was later totally removed at surgery. The patient presented again with a new SAH from a spinal AVM that was also totally removed at surgery. Coexistence of spinal and cerebral arteriovenous malformations are exceedingly rare and hemorrhage from each is not previously reported. This case emphasizes the importance of investigating the spinal canal in otherwise unexplained spontaneous SAH.

✓ We have operated on 12 of 14 cases of arteriovenous malformation (AVM) in the posterior fossa since 1968, with one death. The lesions were in the cerebellum in 10 cases (three anteromedial, one central, three lateral, and three posteromedial), and in the cerebellopontine angle in two; in two cases the lesions were directly related to the brain stem. The AVM's in the anterior part of the cerebellum were operated on through a transtentorial occipital approach.

✓ A series of 250 surgically treated cerebral arteriovenous malformations (AVM's) is presented, in which 22 lesions were located primarily in the thalamus and caudate nucleus. A standardized interhemispheric approach through the posterior corpus callosum and into the atrium of the lateral ventricle was utilized for the surgical removal of these AVM's. Total removal was confirmed by angiography in 18 patients; removal was subtotal in four cases. There were no deaths in this group of patients. Disturbances of recent memory pre- and postoperatively were seen in half of the patients, but most of these deficits were temporary. Other complications included: postoperative homonymous hemianopsia (six cases), transient hemiparesis (three cases), hemisensory loss (two cases), Parinaud's syndrome (one case), and recurrent hemorrhage 2 years after surgery (one case). All 22 patients returned to their previous occupations and are leading independent lives. The results of this experience indicate that thalamocaudate AVM's can be effectively treated by resection.

✓ This report describes the successful excision of a congenital vertebral arteriovenous malformation in an 8-year-old child. There was mild effort dyspnea and left ventricular cardiac enlargement; a left-to-right vertebral artery steal across the basilar trifurcation was a major consideration in planning the surgical approach.

✓ It is believed that surgical excision of arteriovenous malformations is the best treatment when technically feasible without causing significant damage to adjacent brain. The introduction of polymers or particulate emboli by catheter has been used either alone or as an adjunct in attempts to reduce the size of these lesions prior to surgery; however, it is seldom possible to embolize the entire malformation. The authors have used direct injection of a 50% mixture of bucrylate and iophendylate into the feeding arteries supplying the area at craniotomy, with success in three cases. The cases are described to illustrate the method.

✓ A useful variation of an established technique is described for embolization of cerebral arteriovenous malformations. Silastic sponge emboli that fit into No. 16, 17, and 18 stub adapters are passed through standard-sized transfemoral catheters. Of 28 treated patients, obliteration was regarded as very successful in 16. Partial success was achieved in four. Eight were regarded as failures because the reticulum was too large for these microemboli.

✓ Occlusion of the parent artery is a traditional method of treatment of unclippable cerebral aneurysms. Surgical or endovascular occlusion of the parent artery proximal to the aneurysm has been recommended for the treatment of dissecting aneurysms located in the vertebrobasilar circulation. Nevertheless, occlusion of the parent artery may not result in permanent exclusion of the aneurysm from the systemic circulation because, occasionally, postoperative rebleeding occurs after proximal occlusion. Alternatively, endovascular occlusion of the affected site, including the aneurysmal dilation, and parent artery, is a safe and reliable treatment for dissecting aneurysms. The authors present two rare cases of ruptured vertebral artery (VA) dissecting aneurysms that were treated by endovascular occlusion of the affected site including the aneurysm and parent artery by using Guglielmi detachable coils. In both cases the VA recanalized in an antegrade fashion during the follow-up period. Based on these unique cases, the authors suggest that a careful angiographic follow up of dissecting aneurysms is required, even in patients successfully treated with endovascular occlusion of the affected artery and aneurysm.

✓ There is controversy as to the possible toxic effects of isobutyl-2-cyanoacrylate (bucrylate) when this substance is used for purposes of therapeutic embolization. Two cases are presented in which cerebral arteriovenous malformations were resected, one 42 days and the other a year after bucrylate embolization. In both, pathological examination revealed a brisk intimal foreign-body giant-cell reaction wherever bucrylate was present in a vessel, along with chronic inflammation in the vessel walls and adjacent brain parenchyma. The findings are discussed in the light of other observations on the histotoxicity of bucrylate.

✓ The authors report the case of a patient with subarachnoid hemorrhage in whom an intracranial dural arteriovenous malformation coexisted with a spinal arteriovenous malformation. The latter was considered to be the source of the hemorrhage by clinical and radiographic criteria. It is concluded that patients with subarachnoid hemorrhage who show no suitable intracranial source for their bleed in some instances should be investigated for a spinal origin of hemorrhage.
