Background: Cerebral emboli is a rare complication of endovascular procedures and foreign bodies in the cerebrovascular system can lead to stroke. When an intravascular foreign body is identified, endovascular retrieval should be attempted due to its high success rate and minimal morbidity. Case Description: A 59-year-old male patient underwent cine-coronario-graphy through a trans-radial approach because of angina. During the study, a 6Fr catheter fragment ruptured, detached and migrated to a right middle cerebral artery branch. We recovered it with a coronary balloon. Conclusion: A coronary angioplasty balloon is an option for retrieving foreign objects or device fragments that have migrated into cerebral vasculature.

We report the successful treatment of multiple ruptured fusiform middle cerebral artery (MCA) aneurysms in a 10-month-old girl. This previously healthy infant presented with subarachnoid haemorrhage and was found to have multiple irregular dilatations of the superior division branch of the right MCA. Cerebral angiography was performed and confirmed the presence of multiple fusiform aneurysms of the MCA. After multidisciplinary team discussion, it was decided to treat the aneurysms with endovascular approach, using a flow-diverter. Microsurgical clipping was deemed risky because of the high likelihood of parent artery occlusion and expectant management was also considered inappropriate because of the risk of re-bleeding. Dual antiplatelet therapy was started, and a flow-diverter was successfully delivered in the superior division branch of the right MCA. The post-operative course was uneventful, MRI at 12 months did not show any sign of recurrence and at 3 years of age the patient had a normal neurological examination.

Abstract Background Although intracranial traumas by penetrating foreign objects are not absolute rarities, the nature of trauma, the kind of object, and its trajectory make them a one of a kind case every time they occur. Whereas high-velocity traumas mostly result in fatalities, it is the low-velocity traumas that demand an individualized surgical strategy. Methods We present a case report of a 33-year-old patient who was admitted to our department with a self-inflicted transorbital pen injury to the brain. The authors recall the incident and the technique of the pen removal. Results Large surgical exposure of the pen trajectory was considered too traumatic. Therefore, we opted to remove the pen and have an immediate postoperative computed tomography (CT) scan. Due to its fragility, the pen case could only be removed with a screwdriver, inserted into the case. Post-op CT scan showed a small bleeding in the right peduncular region, which was treated conservatively. The patient was transferred back to intensive care unit and woken up the next day. She lost visual function on her right eye, but suffered from no further neurologic deficit. Conclusion Surgical management of removal of intracranial foreign bodies is no routine procedure. Although some would favor a large surgical exposure, we could not think of an approach to do so without maximum surgical efforts. We opted for a minimal surgical procedure with immediate CT scan and achieved an optimal result. We find this case to be worth considering when deciding on a strategy in the future.

Abstract OBJECTIVE In this study, we aimed to investigate the use of a radial artery graft for bypass of the maxillary artery (MA) to the proximal middle cerebral artery (MCA) as an alternative to superficial temporal artery-to-MCA anastomosis or extracranial carotid-to-MCA bypass using long grafts. METHODS Five adult cadavers were used bilaterally. After a frontotemporal craniotomy and a zygomatic arch osteotomy, the MA was found easily 1 to 2 cm inferior to the infratemporal crest. A hole was created with a 4-mm-tip drill in the sphenoid bone 2 to 3 mm lateral to the foramen rotundum extradurally, and the dura over the hole was opened. After the carotid and sylvian cisterns had been opened, the M2 segment of the MCA was exposed. The graft was passed through the hole to reach the M2 segment. Then, the MA was freed from the surrounding tissue and was transected before the infraorbital artery branch. The radial artery graft was anastomosed end-to-end to the MA proximally and end-to-side to the M2 segment of the MCA distally. RESULTS The mean thickness of the MA before the infraorbital artery branch was 2.6 ± 0.3 mm. The mean thickness of the largest trunk of the MCA was 2.3 ± 0.3 mm. The average length of the graft was 36 ± 5.5 mm. CONCLUSION MA-to-MCA bypass is as feasible as proximal MCA revascularization using long vein grafts. The thickness of the MA provides sufficient flow; the length of the graft is short, and it has a straight course. MA-to-proximal MCA bypass may be an alternative to superficial temporal artery-to-MCA as well as extracranial carotid-to-MCA bypasses.

Khat is a stimulating agent used by many people in the Horn of Africa and the Arabian peninsula. Khat chewing is a known cardiovascular risk factor and is thought to cause vasoconstriction, systemic hypertension, and thrombogenicity. A 33-year-old Somalian man initially presented with loss of neurological function of the left arm, hazy vision, and headache. He smokes tobacco and chews two bundles of khat a week for more than 10 years. His ECG on admission showed a Q wave in V1 and V2 and 2 mm ST-elevations in V1, V2, and V3 and a terminal negative T wave in I, aVL, V2, V3, and V4, consistent with a recent, evolving anterior infarction. A noncontrast enhanced CT of the brain showed ischemia in the right middle cerebral artery vascular territory. An MRI showed recent ischemia in the vascular territory of the posterior division of the right middle cerebral artery. Coronary angiography showed a 70% stenosis with haziness of the proximal left anterior descending artery. Diagnostic tests and imaging are consistent with recent myocardial infarction in the LAD vascular territory because of coronary spasm and cerebral infarction in the middle cerebral artery vascular territory probably related to khat chewing.

A case of a giant aneurysm of the right middle cerebral artery treated with Guglielmi detachable coils is reported. Extracranial to intracranial bypass had previously been performed and surgical trapping had been attempted. During the endovascular procedure, balloon test occlusion of the middle cerebral artery was performed in order to demonstrate clinical and angiographic tolerance to parent vessel occlusion. A previous occlusion test in the right common carotid artery did not show sufficient flow through the bypass to perform safe parent vessel occlusion. Diagnostic imaging, the endovascular procedure, and haemodynamic aspects in cases in which parent vessel occlusion is required after extracranial-intracranial bypass are described and the literature is reviewed.

The present study was designed to evaluate the neuroprotective effects of Ginkgo biloba leaf extract (EGb761) in male gerbils subjected to focal cerebral ischemia produced by permanent occlusion of the right middle cerebral artery. In this study, gerbils were fed standard chow with or without EGb761 (100 mg/kg/day, i.g.) prior to cerebral ischemia for 1 week. Gerbils were anesthetized and craniectomized to expose the right middle cerebral artery (MCA). The right MCA was constricted with an 8-0 suture to produce a permanent ligation. Infarct volume was assessed by TTC (2,3,5-triphenyl-tetrazolium chloride) staining 24 hours after initiation of cerebral ischemia. Results showed that the EGb761 group had significant reduction of infarct volume 4 and 6 mm from the frontal pole by 40% and 30%, respectively when compared to the control group ( p < 0.05). Mean locomotor activity of gerbils was reduced 24 hours after the occlusion of the MCA in both groups. However, there was no difference in locomotor activity between groups either 30 minutes before or 24 hours after the occlusion ( p < 0.05).
