1 A CASE OF RECURRENT ALTERNATING TRANSIENT HEMIPARESIS Dr. Shunmuga Arumugasamy.S DNB Resident Railway Hospital, Perambur.
2 6 year old school going child. Apparently normal till 3 yrs when she developed In EVENING: Rt. focal clonic seizures -- 2 episodes -- In 1 hr interval -- Each lasting 5 min -- Angle of mouth to Rt. -- No loss of consciousness -- No limb weakness Advised to go to higher centre by a Pvt. practioner.
3 Next day MORNING: Woke with Rt.. sided limb weakness. Loss of speech
4 Admitted in Pvt hospital in Chengalpet CT brain Infarct in Lt. FrontoParietal region. ECHO Heart Coagulation Profile Lipid Profile NORMAL Baseline Inv (CBC,LFT,RFT) - NORMAL
5
6 In a week Speech improved in 6 days with slight stuttering. Minimal distal weakness continued.
7 In ICH, Egmore: MRI BRAIN - Similar findings. Aspirin, Carbamazepine advised.
8
9 New symptoms 2 ½ years later 5 months ago Left sided weakness sudden onset; in MORNING Not able to walk. Unable to hold objects in Lt hand. Lasted for 5 min à then improved. No loss of consciousness. Similar episodic weakness in EVENING Same side Now speech also affected. Lasted 10 min --> then improved.
10 Admitted in our Hospital. O/E Conscious Oriented to time, place & person Comfortable Vitals: Normal. No Neurocutaneous markers seen.
11 CNS Examination Higher Mental Functions: Speech Aphasic Cranial Nerves: 7 th (Lt) UMN type Facial palsy
12 Motor System: Bulk Tone Power UL - 3/5 (L) - 4/5 (R) Normal LL - 5/5 ( R & L)
13 Reflexes: Superficial : Present; Plantar Left Right - DTR : Exaggerated (L) ; Normal (R) No involuntary movements. Gait Hemiplegic gait. Spine and Cranium Normal. Bladder and Bowel Normal. CVS, RS, Abdomen - Normal.
14 Provisional Diagnosis : Rec. Alternating Transient Hemiparesis
15 DD 1. Procoagulant states. 2. Carotid thromboembolic disease 3. Blood dyscrasias and stroke 4. Vasculitides 5. Basilar artery thrombosis 6. Metabolic disorders (MELAS, Homocysteinuria, Methyl malonic acidemia, Fabry disease) 7. Cerebral Aneurysms
16 INVESTIGATIONS Pr C, Pr S, AT-III, Factor V Leiden Normal. AntiPhospolipid, Anticardiolipin, Lupus anticoagulant antibodies Negative. Blood Lactate Normal. Carotid Doppler Normal. PH Normal ESR Normal Serum homocysteine levels - Normal
17 CT angiography - Revealed the Diagnosis
18
19 The petrous, cavernous and supraclinoid parts of right ICA appears thin calibered. Left ICA reveals critical stenosis beyond its P1 segment. Distally reformatted by collaterals. Anterior cerebral arteries appear normal on both sides. Basilar artery and both vertebral arteries are normal. Puff of Smoke appearance of Collaterals.

24 Diagnosis MOYA-MOYA DISEASE
25 Neurosurgical intervention: (VHS,Adyar) Revascularization procedure (Galeo arachnoid synanastamosis) with multiple burr holes done. Carbamazepine and Aspirin continued. Physiotherapy and Speech therapy continued.
26 Presently Able to walk. Able to eat with Rt. hand with minimal spilling. Left side weakness improved. Continues to be Aphasic.
27 Moya-Moya Disease Moya moya disease was first described in Japan in Progressive steno-occlusive disease at terminal portions of the bilateral internal carotid arteries with the development of "moyamoya vessels" as collateral channels of circulation. Moya moya syndrome - same angiographic appearance associated with conditions such as arteriosclerosis, autoimmune disease, Down syndrome, head trauma, meningitis, neurofibromatosis type 1, and previous radiation therapy.
28 Bilateral concentric stenosis or occlusion of the distal internal carotid arteries and the proximal anterior and middle cerebral arteries are consistent pathologic lesions. Rarely, the posterior cerebral artery or other vessels of posterior circulation are involved. Diffuse collateral reticulate network of vessels (moya moya vessels) - Hallmark of the disease.
29 Etiology: Unknown - though myriad bacterial, environmental, genetic, and viral causes have been theorized. HLA class II association + Familial
30 Extracranial involvement: Renal, pulmonary, and coronary vessels.
31 Diagnosis Cerebral angiography - Gold standard. MRI and MRA other methods of diagnosis but inferior to Cerebral Angiogram. Cerebrospinal fluid exmn. Unremarkable EEG - can be abnormal but are usually nonspecific.
32 Management No known treatment is curative. Medical: Anticoagulant and antiplatelet agents have shown no remarkable benefit. Corticosteroids not beneficial.
33 Surgical treatment: Main modality of Treatment. To manage the hemorrhagic and ischemic consequences of moyamoya disease. Revascularization procedures. Direct Indirect
34 Direct usually in adults; Superficial temporal artery to middle cerebral artery bypass or Middle meningeal artery to middle cerebral artery bypass.
35 Indirect - traditionally used in children. GaleoArachnoidsynanastamosisby multiple burr holes. Encephaloduroarteriosynangiosis (EDAS) Encephalomyosynangiosis (EMS) Omental Transposition Encephalomyoarteriosynangiosis (EMAS) Increase perfusion in the cerebrovascular territory of the middle cerebral artery. Do not substantially effect the circulation in the fields of the anterior or posterior cerebral arteries.
