Delayed angiography in the investigation of intracerebral hematomas caused by small arteriovenous malformations.

We reviewed the clinical and radiological features of ten patients with small arteriovenous malformations that caused intracerebral hematomas. In six patients, angiography showed a small nidus (less than 1 cm in diameter) with a shunt at the site of the hematoma, and in four only an early-filling vein was evident. Six patients had only delayed angiography (4 weeks or more after the ictus). In three, angiography within 2 days of the ictus failed to reveal the cause of the bleed, but repeat angiography showed an early-filling vein in two, and a nidus with shunting in one. In only one patient did early angiography reveal the malformation. MRI was obtained in eight patients, and in two prominent vessels were evident in the wall of the hematoma cavity. In investigation of an unexplained intracerebral hematoma, MRI may be useful to exclude a neoplasm or cavernoma, although the latter may be not be evident in the presence of a recent hematoma. We suggest early MRI and angiography for investigation of an unexplained, nonhypertensive intracerebral bleed, with follow-up MRI and delayed angiography if the initial studies fail to reveal the cause.

Preoperative embolization of brain and spinal hemangioblastomas.

Large hemangioblastomas can be difficult to resect because of excessive bleeding. We report our experience with two patients whose large hemangioblastomas were embolized preoperatively and were totally resected with minimal blood loss and satisfactory postoperative outcome. Embolizations were carried out within 3 days of surgery, with the patient under general anesthesia, with 150- to 250-microns Contour emboli. A 65-year-old woman with progressive, severe myelopathy from a 4.5 x 2.1 x 1.4 cm intramedullary hemangioblastoma at T4 underwent embolization of the left T2 and T3 intercostal arteries; a 29-year-old man with Lindau's syndrome and posterior fossa hemorrhage from a 3.8 x 1.8 x 1.8 cm right cerebellar hemangioblastoma underwent embolization of the right posterior inferior cerebellar artery, two right anterior inferior cerebellar arteries, and a dural branch of the right vertebral artery. Embolization led to the complete obliteration of the tumoral blush without neurological sequelae. Both lesions were completely resected with a blood loss of 50 to 100 ml, with bleeding occurring mainly from the pseudocapsule of the lesion. Preoperative embolization of hemangioblastomas is a useful and relatively safe procedure that reduces blood loss at the time of surgery and allows complete resection.

The variable presentations of craniocervical and cervical dural arteriovenous malformations.

The authors reviewed four patients with dural arteriovenous malformations in the upper spinal axis. Two were at the foramen magnum and two were lower cervical. The patients presented with subarachnoid hemorrhage, a slowly progressive cervical myelopathy, a rapidly progressive thoracic myelopathy, and tinnitus with a sixth nerve palsy. This report emphasizes the importance of studying both the intracranial dural vessels as well as the supply to the cervical spine in searching for a spinal arteriovenous malformation. Subarachnoid hemorrhage with negative cerebral angiography requires spinal angiography if there are any signs or symptoms suggesting cord or nerve root dysfunction. Embolization by an endovascular approach resulted in an angiographic cure in two patients. A combination of embolization and surgery resulted in obliteration of the arteriovenous malformation in one patient. Embolization achieved a clinical cure in one patient, and clinical improvement in two patients.

Cerebral arteriovenous malformations with associated arterial aneurysms: hemodynamic and therapeutic considerations.

The common vascular anomalies of cerebral aneurysm and arteriovenous malformation may exist independently, or together as part of a closely related hemodynamic pairing. Resection or embolization of an AVM may be followed by a decrease in local blood flow, and lead to regression of a suitably situated proximal aneurysm. However, aneurysms located outside the angioarchitecture of the AVM, which remain flow-unrelated to the malformation, will likely not regress, and may in fact enlarge. Two cases are presented which demonstrate these vascular relationships, in order to better understand the regional hemodynamics of these anomalies prior to surgical or endovascular treatment planning.

Interhemispheric cyst of neuroepithelial origin in association with partial agenesis of the corpus callosum. Case report and review of the literature.

The authors report an adult patient with a symptomatic interhemispheric cyst demonstrated by computerized tomography (CT), angiography, and at surgery. Choroid plexus epithelium was identified arising from the inner aspect of the cyst wall. Partial agenesis of the corpus callosum is postulated on the basis of the CT findings and the presence of choroid plexus in the interhemispheric cyst.

Micro-arteriovenous malformations of the brain: superselective angiography in diagnosis and treatment.

PURPOSE: We assessed the usefulness of superselective angiography in patients with micro-arteriovenous malformations. PATIENTS AND METHODS: Five patients had superselective angiography for either diagnosis or treatment of brain arteriovenous malformations having a nidus of less than 1 cm. All patients presented with an intracerebral hematoma. RESULTS: In one patient superselective angiography confirmed the presence of a shunt that was suspected due to visualization of an early vein on the follow-up angiogram; in another patient superselective angiography was helpful in defining the topography of the malformation; in the remaining three patients, superselective angiography was used for embolization of the malformation. We were unsuccessful in achieving a complete angiographic cure in these 3; however, superselective angiography revealed an aneurysm in one that was obliterated by the liquid adhesive embolic agent. CONCLUSION: With the recent advances in microcatheters, superselective angiography has a promising role in defining the topography and angioarchitecture of micro-arteriovenous malformations. Micro-arteriovenous malformations may not be angiographically evident at the time of initial hemorrhage due to the hematoma. With future technical advances it may be possible to completely obliterate these malformations by embolization alone.
