4 proptosis, hyperemic conjunctiva, and chemosis
proptosis, hyperemic conjunctiva, and chemosis. Slit lamp examination revealed tortuous conjunctival and episcleral vessels tortuous corkscrew-type blood vessels in the conjunctiva that come up to the limbus and appear different from those seen with other causes of red eye. In contrast to generalized conjunctivitis, these vessels are localized to certain areas, such as the interpalpebral conjunctiva.

6 MRI On CT, there is dilation of the superior ophthalmic vein and mild right-sided prop-tosis (2). The MRA demonstrates the abnormal signal in the left and posterior right cavernous sinus (3,4). enlargement of extraocular muscles 1. Distension of Rt. superior ophthalmic vein 2. Soft tissue swelling in right orbit, either by inflammation or congestion. 3. Fluid collection with diffusion restriction in the Lt. maxillary sinus with dark SI involving Lt. maxillary sinu, maxillary infundibulum, and hiatus seminlumaris, accompanying destruction of Lt. med. orbital wall : RO fungal sinusitis. 4. A small cystic change in left frontal periventricular region, suggesting old lacunar infarction. 5. Probable reversed venous flow at left internal jugular vein and sigmoid sinus (left).

18 Risk factors Systemic vascular diseases
DM, Hypertension, carotid insufficiency Ocular diseases Open angle glaucoma, ischemic optic neuropathy, pseudotumor cerebri, tilted optic nerve heads Hematologic alterations Hyperviscosity syndromes, dysproteinemias, blood dyscrasias, anemia, elevated plasma homocysteine, factor XII deficiency, anti-phospholipid antibody syndrome, activated protein C resistance, protein C or S deficiency Inflammatory/autoimmune vasculitis : SLE Medications : oral contraceptives, diuretics, Hepatitis B vaccine Infective vasculitis : HIV, syphilis, herpes zoster, sarcoidosis

19 CCF 발생기전 유발원인 아직 명확히 밝혀져 있지는 않음 선천질환 ?
해면정맥동내에 정맥혈전이 형성된 후 경막동맥의 얇은 벽이 파열되어 동정맥루가 형성 - 폭넓은 지지. 유발원인 고혈압, 동맥경화 등의 혈관질환 Ehlers-Danlos 증후군과 같은 교원질환 드물게 수술이나 경한 외상 후

23 During early phase visual impairment is initiated by stagnant-flow anoxia -> ischemia of optic nerve, mechanical, axonal conduction block of optic nerve caused by elevated IOP or compression of optic nerve or chiasm by distended cavernous sinus retina appears normal visual impairment is reversible

24 if high pr. generated by fistula continues
irreversible optic neuropathies, optic nerve atrophy, infarction,trauma to nerve CCF with visual impairment, fistula obliteration is urgently required to prevent irreversible change when vision worsen to blindness, recovery is not possible despite successful CCF embolization

25 증상 결막충혈, 안구돌출, 복시, 시력저하, 안구운동마비 등 안과적 증상이 가장 흔함
주로 중년 이후의 여성 드물게 남성, 소아, 영아 합병증 폐쇄각녹내장,망막중심정맥폐쇄, 증식성 망막병증, 허혈성 시신경병증 뇌피질정맥 으로 배출로가 형성되어 뇌내출혈 증상 결막충혈, 안구돌출, 복시, 시력저하, 안구운동마비 등 안과적 증상이 가장 흔함 두통, 이명, 청진상 잡음

26 Orbital Sxs: retrograde venous flow or pressure of CS -> elevation of venous pr. in orbit chemosis, exophthalmos, bruit, eyelid swelling, decreased vision, increased IOP, ocular pain, retinal hemorrhage ٭ Visual loss mech. 1. retinal ischemia blood away from ophthalmic a. in high flow 2. marked elevation of intraorbital venous pr. -> reduce AV gradient in retina -> compromise retinal perfusion

27 Cavernous Sx: steal phenomenon of blood supply to CN bulging or elevated pressure of CS ptosis, diplopia, anisocoria, ophthalmoplegia 6th palsy (m/c in Type A, location) ٭ diplopia mech 1. cranial n. dysfx. resulting from arterialized pr. within CS and ischemia of the vasa nervosum 2. restriction of extraocular m. (vascular engorgement of m.) Cerebral Sx: reflux into petrosal vein into perimesencephalic, cerebellar vein hemorrhage, infarction

28 이러한 증상을 결정하는 요소로 특히 해면정맥동에서의 배출로의 방향이 중요.
이러한 증상을 결정하는 요소로 특히 해면정맥동에서의 배출로의 방향이 중요. 후방의 상추체정맥동(superior petrosal sinus)이나 하추체정맥동 (inferior petrosal sinus) 안구운동신경의 마비나 외안근의 이상으로 복시가 나타나기도 하나 대부분 무증상 전방의 상안정맥 대부분 결막충혈, 안구돌출, 이명과 같은 증상과 안압상승, 망막혈관 확장 .

29 Diagnosis CT MRI MRA Cerebral arteriography
relatively low sensitivity for detection of AVMs calcification and hypodensity may be noted MRI more sensitive in detection of small hemorrhagic foci ass. with AVM cavernous sinus tumors that may mimic CCF MRA demonstrate feeding a. and draining v. Cerebral arteriography ‘‘gold standard’’

30 Barrow et al, 1985 (based on angiographic criteria(a. supply pattern)
Type A (Direct) direct shunts btw the ICA and CS mainly due to trauma (including iatrogenic) intracavernous ICA aneurysm abnormalities in collagen deposition and the media of a. (Ehlers-Danlos syndrome, fibromuscular dysplasia, pseudoxanthoma elasticum) high-flow lesion not to resolve spontaneously Type B,C,D (Indirect); dural AVF based on source of the feeding arteries cause:unclear high or low flow likely to spon. thrombosis therapy; Sxs, drainage pattern

31 Type B feeding vessels from the intracavernous ICA Type C from only the external carotid artery Type D from ICA and external carotid artery

32 Treatment cause symptoms and clinical course angiographic features
Decision: cause symptoms and clinical course angiographic features patient’s medical condition manual carotid compression microsurgery endovascular treatment radiosurgery combine
