✓ Seven cases of giant posterior hemisphere arteriovenous malformations are described. The significance of meningeal feeding vessels from the external carotid artery in addition to the primary cerebral supply through the internal carotid and vertebral arteries to these malformations is discussed. The necessity of bilateral selective external carotid arteriography is stressed, and the value of preoperative embolization is questioned.

Arteriovenous malformations (AVM) are congenital vascular lesions fed by arterial feeders originating from branches of the internal carotid artery (ICA) or vertebrobasilar artery. We experienced unique AVMs arising in the midline Galenic region, receiving blood supply from the ICA/vertebral artery systems and the external carotid artery system. We retrospectively reviewed data on eight patients who had an AVM arising in the Galenic region and were treated in the University of Tokyo Hospital between 1990 and 2019. The median age at diagnosis was 62 years. Three cases (38%) presented with obstructive hydrocephalus due to aqueduct obstruction caused by an engorged vein of Galen. In all cases, feeders from dural arteries were present and the vein of Galen was the primary drainer. All patients underwent stereotactic radiosurgery. Five patients were followed for > two years; nidus obliteration was confirmed in one, and > 75% shrinkage was confirmed in three, while one patient died due to hemorrhage. Altogether, AVMs arising in the Galenic region are rare and exhibit several peculiar characteristics including the presence of dural feeders, an older age at presentation and presentation with obstructive hydrocephalus.

✓ Arteriovenous malformations located within cerebral parenchyma are usually supplied by intracranial vessels. An extracranial blood supply to these lesions is rare. The authors report their experience with two such cases and discuss the 21 comparable reports.

Abstract The operative and histopathological findings in 31 cases of intracranial meningioma after preoperative embolization with Gelfoam and/or lyophilized dura mater are reported. Removal of the tumor after embolization was facilitated in those meningiomas fed exclusively or mainly by branches of the external carotid artery (29 of 31). Large areas of tumor necrosis were never seen on histopathological examination, even when suggested by large regions of decreased density on the postembolization computed tomographic scan. Preoperative embolization of the feeding vessels arising from the external carotid artery system has proven to be a useful adjunct before the resection of intracranial meningiomas.

✓ The reconstruction of the external carotid artery (ECA) and obliteration of an occluded stump or atretic internal carotid artery (ICA) are described. In this method the occluded ICA is used as an autologous patch graft. Satisfactory ICA obliteration and expanded, smooth common carotid artery—ECA contour were obtained in three patients. Advantages of this procedure include ICA obliteration and precise patch placement by using an ideal, autologous, arterial graft.

Pitfall during the embolization and evaluation after the embolization for skull base meningiomas supplied by meningeal arteries of internal carotid artery (ICA) are reported. This study includes 15 cases of skull base meningiomas (two males and 13 females) that supplied by meningeal branches of internal carotid artery. The preoperative embolization was performed by these feeders. MRI findings and serum levels of C-reactive protein (CRP) after the embolization were examined. In ten patients among 15 patients the meningeal branches of ICA were dominant feeders. In ten patients out of 15 patients, the embolization from the meningeal branches of ICA was possible. Eight patients out of these ten patients were suffered from high fever and increase of serum level of CRP after the embolization. During the embolization for skull base meningiomas, the existence of collateral pathways between the ICA system and external carotid artery system were identified. The increase of serum levels of CRP might be recognized in the patients that effective embolization were performed.

✓ Nineteen patients underwent a total of 21 stump angioplasty procedures for an occluded internal carotid artery. Indications for surgery included the preparation of the donor vessel for a subsequent extracranial-intracranial bypass procedure, the occurrence of emboli to the intracranial vasculature from the external carotid artery circulation, and the association with symptomatic occlusive disease of the external carotid artery accompanying occlusion of the ipsilateral internal carotid artery. The technique utilized and the results obtained in these 19 patients are presented. In select patients, the removal of an occluded internal carotid artery stump via a stump angioplasty is beneficial in preventing the catastrophic sequela of embolic cerebrovascular disease.

✓ Over a 2-year period the authors have studied the effects of preoperative subselective embolization of meningiomas. Thirty-six consecutive patients shown by computerized tomography (CT) to have a meningioma underwent selective internal and external carotid artery angiography, and any significant external carotid artery feeders were embolized (27 cases). It was found that CT and dynamic radioisotope scan findings were unable to predict the degree of vascularity of the tumor or its suitability for embolization. Furthermore, these tests, repeated after embolization, were unreliable in detecting either the extent of necrosis or reduction in blood flow. The effects of embolization upon surgery were recorded, and the excised tumor specimen examined for evidence of thrombosis and infarction. Subselective embolization was determined to be a simple, safe, and effective method of producing tumor necrosis and intraoperative hemostasis in selected patients.

✓ Spontaneous hemorrhage into the ventricles in premature babies is a major problem, and neither its cause nor its pathogenesis is understood. A model is presented for the study of germinal matrix and intraventricular hemorrhage in the preterm rabbit. This animal is particularly suitable because like the human, 1) the maximal growth of the brain occurs perinatally; 2) there is an abundant germinal matrix near term, and by birth this is substantially reduced; 3) there is no rete mirabile; 4) the blood flow to the brain is via internal carotid and vertebral arteries; 5) the maturation of the lungs is completed just before term; and 6) the rabbit pup can maintain a separate existence from the dam when delivered prematurely. Eight of 64 such animals were found to have developed spontaneous germinal matrix hemorrhage with or without rupture into the ventricles. Several physiological and chemical features characteristic of the premature rabbit are presented. The hemorrhage in the lagomorph might be a paradigm of that in infants, and its study may aid in the understanding of the pathogenesis of the process.

✓ The authors describe a system comprising a small latex balloon attached to a Teflon catheter. The balloon has a distal calibrated leak which is used for intravascular embolization with isobutyl-2-cyanoacrylate. The balloon is easily detached after embolization. The combination of manual control of the balloon-catheter system, plus the ability of the balloon to navigate intra-arterially with the blood flow, makes this system suitable for superselective angiography and embolization of lesions supplied by the external carotid artery (ECA). This system avoids intimal dissection and concomitant arterial vasospasm when trying to negotiate steep distal curves of the ECA branches. Experimental embolization of several branches of the ECA in the dog, and clinical examples of treatment of dural arteriovenous malformations in three patients are described.

✓ Ligation of the external carotid artery induced an increased flow in the internal carotid artery in the monkey (Macaca radiata). Bilateral external carotid artery ligations were then done in patients with ischemia resulting from “stroke”; studies of internal carotid artery blood flow showed a consistent increase in flow.
