Internal maxillary artery to intracranial artery bypass: a case series of 31 patients with chronic internal carotid/middle cerebral arterial-sclerotic steno-occlusive disease.
CONCLUSIONS: By supplying an adequate flow to a larger flow territory of chronically stenotic/occlusive major cerebral arteries, IMA bypass surgery is efficient for restoring hemodynamics in selected patients and improving their neurological deficits.

The syndrome of transient headache and neurological deficits with cerebrospinal fluid lymphocytosis mimicking an acute stroke
ConclusionsThe decision to thrombolyse or perform an LP in HaNDL patients mimicking a stroke is difficult in the acute setting. Perfusion CT can provide misleading results and CTA may be useful in ruling out occlusion of a cerebral vessel.

Case Report - IV Thrombolysis with Subsequent SAH in Setting of Occult Spontaneous MCA Dissection (P4.346)
Conclusions: Spontaneous isolated middle cerebral artery dissection is a rare entity which most commonly presents as ischemic stroke and may complicate the administration of IV-rtPA. It should be considered in cases of thrombolysis and development of subsequent SAH.Disclosure: Dr. Saeed has nothing to disclose. Dr. Chaudhry has nothing to disclose.

Acute Stroke Due to High Voltage Electrocution (P4.347)
We present a case of acute stroke due to high voltage electrocution. Case presentation 38 year old white male accidently grabbed a live wire in the field and got electrocuted. He sustained 2nd degree electric burns at the entry wound in his right palm with a small exist wound in the right foot. On admission, he was stable with total amnesia of the incident event. He had no major medical, psychiatric or substance abuse problems. He remained confused in the hospital with expressive aphasia. Repeat CT scan of the head showed multiple hypo density in both frontal and left partial region. MRI confirmed the presence of acute isc...

Stroke Due to Air Embolism Related to Laser Ablation of Accessory Vein (P4.357)
Conclusions: Air embolism leading to devastating stroke may occur few hours after laser treatment of varicose veins. Chest symptoms associated with the procedure should raise the possibility of air embolism. Immediate therapeutic measures like 100[percnt] oxygen, hyperbaric oxygen chamber and/or hypothermia should be considered to prevent neurologic complications.Disclosure: Dr. Kale has nothing to disclose.

Aortic Sarcoma Mimicking a Thrombus Filling Vascular Lumen: A Rare Cause of Cerebral Infarction (P4.364)
Conclusion- Primary aortic sarcoma is an extremely rare cause of stroke. This sarcoma may be misinterpreted as a thrombus filling vascular lumen on CT angiography, but no elevation of D-dimer is incompatible with a large thrombus. The final diagnosis can be made by surgical biopsy.Disclosure: Dr. Kim has nothing to disclose. Dr. Jeon has nothing to disclose. Dr. Park has nothing to disclose. Dr. Kim has nothing to disclose.

Ischemic Stroke After Plasma Donation (P4.365)
Conclusions: Plasma donation may result in arterial thrombosis in patients with a mild hypercoagulable disorder, which is otherwise not phenotypically expressed. Further studies are needed to evaluate plasma donation as a potential etiology for ischemic stroke.Disclosure: Dr. Salahuddin has nothing to disclose. Dr. Hussaini has nothing to disclose.

Unique CT Perfusion Imaging in a Case of HaNDL: New Insight into Pathophysiology of Acute Attacks (P4.114)
Conclusions: The pattern of global left hemispheric hypoperfusion seen in this case supports previous hypotheses of secondary oligemia induced by a hemispheric wave of cortical spreading depression (CSD). However, the right ACA territory hypoperfusion represents a phenomenon never previously reported in this field. We speculate that the secondary vasomotor changes induced by CSD in the left hemisphere, spread to the right hemisphere via the anomalous vascular supply. Such a mechanism of direct vascular propagation through vessel gap junctions has been described in animal studies. This unique case provides a valuable contri...

Intracranial Fibromuscular Dysplasia in a Middle-Aged Woman with Recurrent Ischemic Stroke (P4.388)
Conclusions: FMD is a rare disease and has very rarely been described in the intracranial arteries. This case illustrates the natural history and progression of FMD in this patient and elucidates the limited treatment options for preventing disease progression and secondary complications. FMD most predominantly affects younger to middle-aged females and if the disease process goes unrecognized it can have devastating consequences. It is important to continue research endeavors into the genetic and biologic determinants of FMD in order to develop better prevention and therapeutic strategies for this condition.Disclosure: Dr...

Mucor Thrombus
Conclusions The endovascular placement of an expandable stent in the setting of angioinvasive mucormycosis restored good cerebral blood flow in a proximal internal carotid artery occlusion. The patient’s aphasia resolved following this intervention. Artifacts of CT angiography may result in the overestimation of acute arterial occlusions. Endovascular carotid stenting may be a palliative measure in the setting of angioinvasive rhino-cerebro-orbital mucormycosis.

De Novo Arteriovenous Malformation Growth Secondary to Implantation of Genetically Modified Allogeneic Mesenchymal Stem Cells in the Brain
CONCLUSION: The development of an AVM within a period of 3 years after implantation of the glucagon-like peptide-1–secreting mesenchymal stem cells suggests a possible relationship. This case exemplifies that further investigations are necessary to assess the safety of genetically modified cell lines for local biological drug delivery in the brain.

Report of Dramatic Improvement after a Lumboperitoneal Shunt Procedure in a Case of Anticoagulation Therapy-Resistant Cerebral Venous Thrombosis
Cerebral venous thrombosis (CVT), which typically progresses from either acute or subacute onset, presents with symptoms related to intracranial hypertension (e.g., headache and papilledema) and brain parenchymal lesions (e.g., aphasia and hemiplegia). Anticoagulation therapy is generally accepted as a treatment for CVT and often leads to good clinical outcomes. However, we experienced a case of CVT with an uncommon clinical course. The patient was a 63-year-old man who presented with headache, papilledema, visual loss, and diplopia; his condition gradually deteriorated, and he was diagnosed with CVT via cerebral angiography.

Takotsubo Cardiomyopathy Following Acute Cerebral Events

A case of atraumatic convexal subarachnoid haemorrhage due to unusual cause
Conclusions This case shows that ICA stenosis can cause convexal SAH and it should therefore be added to the differential diagnosis of atraumatic SAH. The association is under recognised and can be missed due to the unusual location of the blood and failure to image the extra cranial carotid arteries.
