Background and Purpose— Multimodal imaging in acute ischemic stroke defines the extent of arterial collaterals, resultant penumbra, and associated infarct core, yet limitations abound. We identified superficial and deep venous drainage patterns that predict outcomes in patients with a proximal arterial occlusion of the anterior circulation. Methods— An observational study that used computed tomography (CT) angiography to detail venous drainage in a consecutive series of patients with a proximal anterior circulation arterial occlusion. The principal veins that drain the cortex (superficial middle cerebral, vein of Trolard, vein of Labbé, and basal vein of Rosenthal) and deep structures were scored with a categorical scale on the basis of degree of contrast enhancement. The Prognostic Evaluation based on Cortical vein score difference In Stroke score encompassing the interhemispheric difference of the composite scores of the veins draining the cortices (superficial middle cerebral+vein of Trolard+vein of Labbé+basal vein of Rosenthal) was analyzed with respect to 90-day modified Rankin Scale outcomes. Results— Thirty-nine patients were included in the study. A Prognostic Evaluation based on Cortical vein score difference In Stroke score of 4 to 8 accurately predicted poor outcomes (modified Rankin Scale, 3–6; odds ratio, 20.53; P <0.001). On stepwise logistic regression analyses adjusted for CT Alberta stroke program early CT score, CT angiography collateral grading and National Institutes of Health Stroke Scale score, a Prognostic Evaluation based on Cortical vein score difference In Stroke score of 4 to 8 (odds ratio, 23.598; P =0.009) and an elevated admission National Institutes of Health Stroke Scale (odds ratio, 1.423; P =0.023) were independent predictors of poor outcome. Conclusions— The Prognostic Evaluation based on Cortical vein score difference In Stroke score, a novel measure of venous enhancement on CT angiography, accurately predicts clinical outcomes. Venous features on computed tomography angiography provide additional characterization of collateral perfusion and prognostication in acute ischemic stroke.

Background: CT angiography source images (CTASI) improve diagnostic accuracy for ischemic brain infarction compared to non-contrast CT (NCCT). We studied whether CTASI alone or combined with the CTA occlusion status may improve patient selection for thrombolysis in an extended time window. Methods: We prospectively observed patients presenting with anterior circulation ischemic stroke within 12 hours from symptom onset and an NIHSS score ≥ 3. All patients underwent cranial NCCT and CTA. Patients were treated with intravenous and/or intra-arterial thrombolysis at the discretion of the treating stroke neurologist and neuroloradiologist. We determined intracranial occlusion status and applied the Alberta Stroke Program Early CT Score (ASPECTS) to CTASI. Primary clinical outcome measure was independent outcome at 3 months, defined as mRS scores 0-2. We calculated unadjusted risk ratios to assess the effect of thrombolysis on functional outcome in patients with: 1) minor ischemic changes on CTASI (CTASI-ASPECTS >5) and 2) patients with minor ischemic changes on CTASI and middle cerebral artery (MCA) occlusion. Results: We enrolled 102 patients with a mean age of 71 +/- 12 years, median onset-to-CTA time of 112,5 (range 37-898) min, a median NIHSS score of 9.5 (3-39), and a median CTASI-ASPECTS of 8. Sixty-two patients (61%) received any thrombolysis (56 IV, 5 IV/IA, 1 IA). MCA occlusion was present in 57 patients (56%), 80/101 (80%) assessable patients had a CTASI-ASPECTS >5 and 37/101 (37%) patients had a CTASI-ASPECTS >5 in the presence of a MCA occlusion. At 3 months, 52 (51%) patients had an independent functional outcome. When patients with CTA-SI ASPECTS > 5 received thrombolysis, 30/46 (65%) achieved an independent functional outcome, whereas 20/35 (57%) without thrombolysis were functionally independent (RR 1.1, CI 95 0.8-1.6). In patients with CTASI-ASPECTS > 5 and additional MCA-occlusion, 13/24 (54%) with thrombolysis and 3/13 (23%) without thrombolysis achieved an independent functional outcome (RR 2.3, CI 95 0.8-6.8). Conclusion: In our non-randomized study, the extent of CTASI hypoattenuation alone did not identify patients benefiting from thrombolysis. In the presence of an MCA-occlusion, however, CTASI might identify patients with benefit from thrombolysis in an extended time window.

Abstract BACKGROUND AND IMPORTANCE: High-grade cavernous sinus (CS) dural arteriovenous fistulae with cortical venous drainage often have a malignant presentation requiring urgent treatment. In the absence of a venous access to the lesion, transarterial embolization can potentially cure these lesions; however, the high concentration of eloquent arterial territories adjacent to the fistula creates a precarious risk of arterial-arterial reflux. In such cases, a combined surgical and endovascular approach may provide the least invasive option. CLINICAL PRESENTATION: We describe a patient presenting with a venous hemorrhagic infarct caused by a high-grade CS dural arteriovenous fistula (Barrow type D caroticocavernous fistula) with isolated drainage via the superficial middle cerebral vein into engorged perisylvian cortical veins. No transfemoral or ophthalmic strategy was angiographically apparent, and the posterior location of the involved CS compartment mitigated a direct puncture. The patient underwent direct puncture of the superficial middle cerebral vein via an orbitozygomatic craniotomy and the CS was catheterized under fluoroscopic guidance. The CS was coil-embolized back into the distal superficial middle cerebral vein with complete obliteration of the fistula. The patient did well with no new deficits and made an uneventful recovery. CONCLUSION: This novel combined open surgical and endovascular approach enables obliteration of a CS dural arteriovenous fistula with isolated cortical venous drainage and avoids the additional manipulation with direct dissection and puncture of the CS itself.

OBJECT The drainage of the superficial middle cerebral vein (SMCV) has previously been classified into 4 subtypes. Extradural procedures and dural incisions during the anterior transpetrosal approach (ATPA) may interrupt the route of drainage from the SMCV. In this study, the authors examined the relationship between anatomical variations in the SMCV and the corresponding surgical modifications to the ATPA that are necessary for venous preservation. METHODS This study included 48 patients treated via the ATPA in whom the SMCV was examined using 3D CT venography. The drainage patterns of the SMCV were classified into 3 types: cavernous or absent (Type 1), sphenobasal (Type 2), and sphenopetrosal (Type 3). Type 2 was subdivided into medial (Type 2a) and lateral (Type 2b), and Type 3 was subdivided into vein (Type 3a), vein and sinus (Type 3b), and sinus (Type 3c). The authors performed 3 ATPA modifications to preserve the SMCV: epidural anterior petrosectomy with subdural visualization of the sphenobasal vein (SBV), modification of the dural incision, and subdural anterior petrosectomy. Standard ATPA can be performed with Type 1, Type 2a, and Type 3a drainage. With Type 2b drainage, an epidural anterior petrosectomy with subdural SBV visualization is appropriate. The dural incision should be modified in Type 3b. With Type 3c, a subdural anterior petrosectomy is required. RESULTS The frequency of each type was 68.7% (33/48) in Type 1, 8.3% (4/48) in Type 2a, 4.2% (2/48) in Type 2b, 14.6% (7/48) in Type 3a, 2.1% (1/48) in Type 3b, and 2.1% (1/48) in Type 3c. No venous complications were found. CONCLUSIONS The authors propose an SMCV modified classification based on ATPA modifications required for venous preservation.

IntroductionPrevious trials rejected a role of extracranial-to-intracranial bypass surgery for managing symptomatic atheromatous disease. However, haemodynamic insufficiency may still be a rationale for surgery, provided it can be performed with low morbidity and that patency is robust.MethodsConsecutive patients undergoing bypass surgery for non-moyamoya symptomatic intracranial arterial stenosis and occlusion were retrospectively identified. The clinical course and surgical outcomes of the cohort were evaluated at six-weeks, six-months, and annually thereafter.ResultsBetween 1992 and 2017, 112 patients underwent 127 bypasses. The angiographic abnormality was arterial occlusion in 80% and stenosis in 20%. Procedures were to prevent future stroke (76%) and stroke reversal (24%), with revascularisation using an arterial pedicle graft in 80% and venous interposition graft (VIG) in 20%. A poor outcome (bypass occlusion, new stroke, new neurological deficit, or worsening neurologic deficit) occurred in 8.9% of patients. The risk of poor outcome was significantly lower with arterial pedicle grafts (Odds ratio=0.15), bypass for prophylaxis against future stroke (Odds ratio=0.11), or anterior circulation bypass (Odds ratio=0.17). Over the first eight years following surgery there were no poor outcomes in the 66 cases exhibiting all three of these characteristics.ConclusionProphylactic arterial pedicle bypass surgery for anterior circulation ischemia is associated with high graft patency and low stroke and surgical complication rates. Higher risks are associated with acute procedures, typically for posterior circulation pathology and requiring VIGs. A carefully selected subset of individuals with haemodynamic insufficiency and ischaemic symptoms are likely to benefit from cerebral revascularisation surgery.

INTRODUCTION: Changes in venous drainage imaging have been directly related to parenchymal damage in acute ischemic stroke during endovascular treatment. Venous asymmetry assessed by CT prior to treatment may be directly related to delayed flow in the hypoperfused territory. We investigated the prevalence of asymmetry in internal cerebral vein (AIV) drainage and its correlation with collateral flow in patients with acute ischemic stroke by a multimodal CT protocol. Subjects and methods: We retrospectively evaluated clinical and radiological data of 29 consecutive patients with acute anterior circulation ischemic stroke within 6 hours from symptoms onset. Collateral status was graded as good or poor depending on the extent of contrast visualized distal to the occlusion on CT angiography (CTA). Presence and AIV (analyzed by density units, time to peak and volume) and arterial collateral score were blinded assessed on CT perfusion (PCT), CTA source images (CTASI) and MIP reconstructions. Results: We included 29 patients, with a median age of 77 ± 15 y, and 31% of them were men. Median baseline NIHSS was 11 ± 7. Mean infarct ASPECTS was 9.3 ± 1 and size 2 cm3 ± 4. Asymmetrical veins were present in 33% of patients. This sign was more prevalent in patients with proximal occlusions than in distal occlusions (67% versus 33%) and in patients with poor collaterals compared to those with good collaterals (62% versus 29%). AIV was significantly associated with increasing age (p= 0.03), increasing baseline NIHSS (p= 0.02) and poor collaterals (p=0.01). Presence of AIV reached high specificity (93%) and good sensitivity (66%) for poor arterial collaterals prediction (p=0.001). Conclusion: Impairment of venous circulation, assessed by means of AIV, is present in one third of the patients and was associated with stroke severity and low effectiveness of collateral flow. Presence of internal veins asymmetry is highly specific in detecting poor collateral circulation in acute stroke and may be a predictor of clinical and radiological severity, possibly useful for patients selection in planning reperfusion therapy strategies.

Thrombolysis with intravenous rt-PA is the current therapy for acute ischemic stroke. Unlike other outcome factors, relatively little is known about the prognostic value of the occlusion site on treatment outcome. We compared the effectiveness and safety of intravenous thrombolysis in patients with different levels of occlusion identified by CT angiography (CTA) in anterior circulation stroke, and analyzed the influence of the occlusion site on treatment outcome in relation to other outcome factors. We selected 71 patients from a stroke database collected between June 2007 and December 2011 at our hospital. All of the studied patients had anterior circulation stroke with intracranial occlusion detected by CTA and were treated with intravenous rt-PA. They were divided into two groups according to the site of occlusion along the middle cerebral artery course: proximal (carotid “T”, complete M1 and mild M1 occlusions) and distal (M2/M3 occlusions). Treatment effectiveness was assessed by modified Rankin Scale (mRS) at three months, considering a positive outcome a mRS value ≤ 2. Treatment safety was assessed by evaluating the rate of hemorrhagic complications seen on unenhanced CT at 24 hours. Binary logistic regression was performed to evaluate the interaction between occlusion site and other variables such as sex, age, ASPECT score on admission and baseline NIHSS value in determining treatment outcome. The degree of effectiveness and safety differed when considering patients with proximal and distal occlusions. The percentage of successfully treated cases was 28.6% in the first group compared to 72% in the second, and the rate of hemorrhagic complications was 28.6% and 6% respectively. After adjustment for sex, age, ASPECT score on admission and baseline NIHSS value, occlusion site was the only variable significantly influencing treatment safety and, together with baseline NIHSS value, the only valid predictor of treatment effectiveness. We demonstrated a correlation between the site of arterial occlusion and outcome of intravenous thrombolysis. By helping the choice of the best therapeutic strategy depending on the identified occlusion site, CTA could be usefully added to the examinations included in the Stroke Protocol for the baseline evaluation of patients with suspected acute stroke.

✓ A unique case of spontaneous regression of giant arteriovenous fistulae during infancy is described in this report. A female infant, the product of normal labor and delivery, demonstrated severe ventriculomegaly and an intracranial hemorrhage at birth. Cerebral angiography at 5 days of age revealed several large fistulae fed by the anterior and middle cerebral arteries draining into the deep venous system through a dilated internal cerebral vein and ectatic vein of Galen. Two days following the angiogram, a second intracranial hemorrhage occurred. Active hydrocephalus developed over the next 6 months and was treated with ventriculoperitoneal shunting. When the child was 8 months of age, angiography failed to demonstrate the fistulae. It was postulated that pressure effects from the intracranial hematoma and long-standing intracranial hypertension as well as stenosis in the anomalous venous outflow resulted in vascular stasis, venous thrombosis, and selective arterial occlusion. Hydrocephalus was a result of the compression of the intraventricular foramina by dilated embryonic vessels. This anomaly, predominantly involving the anterior circulation, may be homologous to the vein of Galen aneurysm in the posterior circulation.
