The clinical case of simultaneous endovascular bloodstream exclusion of arteriovenous malformation and saccular aneurysm in parturient woman is presented. Onyx liquid adhesive composition and monospiral aneurysm occlusion technique were used. Patient X., 31, was hospitalized to the clinic on the 10th day of the postpartum period. From the anamnesis: twice (at 20th and 27th weeks of pregnancy) patient suffered intraventricular hemorrhage due to the rupture of arteriovenous malformation in the posterior third of the corpus callosum, left lateral ventricle and left parietal lobe of the brain. After the first hemorrhage a conservative treatment tactic was determined, given the high risk of complications associated with the surgical intervention for the mother and fetus. After the second hemorrhage endovascular embolization of malformation was suggested, however, the patient and her husband refused surgery, preferring conservative therapy with subsequent surgical treatment after delivery. In addition to the malformation, according to the data of selective cerebral subtraction angiography multiple cerebral saccular aneurysms of the left Anterior Cerebral – Anterior Communicating Artery and 2 Anterior Cerebral Artery aneurysms (A2-A2, A3-A4-segments) on the right side were diagnosed. Endovascular subtotal embolization of arteriovenous malformation and occlusion of the right Anterior Cerebral Artery (A2-A3-segment) saccular aneurysm were performed during the operation. A control angiographic examination after 3 months showed a complete exclusion of these arteriovenous malformation and saccular aneurysm and disappearance of all aneurysms of the left Anterior Cerebral Artery – Anterior Communicating Artery and right Anterior Cerebral Artery (A3-A4-segment).

Background: The circle of Willis (CW) is a vascular network formed at the base of skull in the interpeduncular fossa. Its anterior part is formed by the anterior cerebral artery, from either side. Anterior communicating artery connects the right and left anterior cerebral arteries. Posteriorly, the basilar artery divides into right and left posterior cerebral arteries and each join to ipsilateral internal carotid artery through a posterior communicating artery. Anterior communicating artery and posterior communicating arteries are important component of circle of Willis, acts as collateral channel to stabilize blood flow. In the present study, anatomical variations in the circle of Willis were noted.Methods: 75 apparently normal formalin fixed brain specimens were collected from human cadavers. 55 Normal anatomical pattern and 20 variations of circle of Willis were studied. The Circles of Willis arteries were then colored, photographed, numbered and the abnormalities, if any, were noted.Results: Twenty variations were noted. The most common variation observed is in the anterior communicating artery followed by some other variations like the Posterior communicating arteries, Anterior cerebral artery and posterior cerebral artery (PCA) was found in 20 specimens.Conclusions: Knowledge on of variations in the formation of Circle of Willis, all surgical interventions should be preceded by angiography. Awareness of these anatomical variations is important in the neurovascular procedures.

Large artery atherosclerosis and cardioembolism are the two major subtypes of ischemic stroke. We herein describe a 75-year-old man with acute complete cerebral infarction in the typical territories of the bilateral anterior cerebral artery (ACA) and left middle cerebral artery. Brain magnetic resonance angiography showed that the right A1 segment of the ACA was affected by severe arteriosclerosis and that the right ACA other than the A1 segment was compensated by the left ACA through the anterior communicating artery. Acute cardioembolism only occluded the left anterior circulation but simultaneously blocked the right ACA due to decompensation. We presume that the bilateral cerebral infarctions were caused by chronic atherosclerosis and acute cardioembolism.

Abstract Cortical somatosensory evoked potentials (SSEPs) reflect the functional integrity of somatosensory pathways from the site of stimulation to the primary somatosensory cortex. We used intraoperative monitoring of cortical SSEPs to determine whether the right anterior cerebral artery (RACA), the major feeding vessel of a large arteriovenous malformation (AVM), could be sacrificed without compromising sensorimotor function in the left lower extremity. The SSEPs recorded after test occlusion of the RACA showed preservation of the initial cortical positivity, and the RACA was divided. The AVM was excised completely, and the patient suffered no neurological deficit.

AbstractThis report highlights an unusual variation of Anterior communicating artery of the circle of Willis found during dissection for studying circle of Willis. The brain was carefully extracted out of the skull so that arteries forming the circle of Willis do not get tom. The circle of Willis was identified in the interpeduncular cistern. Fine dissection was done to identify any variations. In this specimen there were double anterior communicating arteries joined in the midline by a short longitudinal segment of artery. Length and external diameters of both the Anterior communicating arteries were measured using Vernier calipers. Also, a medial striate artery (recurrent artery of Heubner) was seen originating from the right anterior cerebral artery just between the junctions of the proximal and distal Anterior communicating arteries with the right Anterior cerebral artery. Knowledge of this variation is valuable to neurosurgeons in planning surgical treatment and has clinical significance in relation to stroke.

The anterior communication artery (ACOM) connects the right and left anterior cerebral artery and establishes contra-lateral flow, permiting perfusion of brain at both sides. While the artery itself is very short in length and small in size, 35% of ruptured aneurysms are found to form at the ACOM [1] and these aneurysms also rupture when they are small [2].

Background: Saccular aneurysm in the distal segment of the middle cerebral artery (DMCA) occurs very rarely and often represents with a rupture. We report a successful surgical case of a DMCA aneurysm rupture with large cerebral and subarachnoid hemorrhage. Case Description: A 44-year-old female presented a sudden onset headache and coma (the Glasgow Coma Scale was 3). Head computed tomography (CT) revealed a subarachnoid hemorrhage around the right Sylvian fissure and large intracranial hematoma in the right parietal lobe. The CT angiography showed a saccular aneurysm in the peripheral cortical segment of the right angular branch of the right DMCA. We decided to perform a right craniotomy to evacuate hematoma and interrupt the aneurysm. Just after the dural incision, the aneurysm ruptured again. We applied a temporary clip on the artery proximal to the aneurysm before excising it. Conclusion: Aneurysm in DMCA can be treated safely with surgical excision and risk of sudden recurrent hemorrhage needs to be anticipated.

The growing dependence on electricity in our daily lives has increased the incidence of electrocution injuries. Although several neurological injuries have been described previously, acute stroke due to electrocution is rare. Our patient, a previously healthy man, was electrocuted after he grabbed a “live” high-voltage wire. Although he was hemodynamically stable, he remained confused with language defects. MRI of the brain showed acute stroke in the bilateral anterior cerebral artery territory and watershed regions of the left middle cerebral artery territory. MR angiogram incidentally showed A1 segment aplasia of the right anterior cerebral artery. Electrocution is known to cause vasospasm leading to end-organ damage similar to that seen in stroke. In our patient, vasospasm of the left anterior circulation likely led to watershed infarcts in the left parietal lobe and bilateral frontal lobes. Due to aplasia of the A1 segment on the right side, perfusion to both frontal lobes was solely from the left anterior cerebral artery.

Cerebral Artery Aneurysm

It is not common for an isolated visual symptom to be the first indication of an aneurysm compressing the optic nerve. The compression can lead to blindness, and a recovery from the blindness is rare. We report a female with a left painless optic neuropathy caused by an unruptured anterior cerebral artery aneurysm. The patient had a temporal hemianopic visual field defect, which progressed to blindness in the left eye, while the right visual function was not affected. A coil embolization of the aneurysm completely restored her visual acuity to 20/20. These findings suggest that aneurysmal lesions should be ruled out in case of unilateral optic neuropathy with hemianopic visual field defects and progressive visual loss.
