Magnetic resonance venography confirmed thrombosis of the straight sinus, left transverse sinus, left sigmoid sinus, left internal jugular vein and cortical veins in the left high parietal region. The patient's thrombophilia profile was positive only for heterozygous Factor V Leiden mutation. The patient was treated conservatively with anticonvulsants and low-molecular-weight heparin. The patient recovered completely within a week and was discharged. Cerebral venous sinus thrombosis (CVST) has been rarely reported in the post-operative period following trans-sphenoidal surgery for pituitary adenoma. Early diagnosis and treatment of CVST is necessary for a favourable outcome.","PeriodicalId":218723,"journal":{"name":"Journal of Cerebrovascular Sciences","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128424218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Distal MCA aneurysm in M2, M3 and M4 segments are rare. Here, we discuss an incidental distal M2 segment aneurysm and its management along with a brief literature review. Fifty-one-year-old male, presented to us with a history of the giddiness of 1-week duration. During the evaluation for giddiness, his computed tomography (CT) brain plain showed a small well-defined hyperdense rounded lesion in the left Sylvian fissure. CT angiogram was done and it showed a saccular aneurysm measuring 7.7 mm × 7.3 mm and had a narrow neck of 1.5 mm arising from the distal M2 segment of MCA. The aneurysm was directed superiorly in the distal MCA. Digital subtraction angiogram showed a 6.4 mm × 6.9 mm distal M2 segment bilobed aneurysm with a neck of 3.8 mm and projecting superiorly. Surgical clipping of the aneurysm was done. Perioperative period was uneventful and the patient is doing well at 3 months follow-up. Review of the literature showed that the incidence of distal MCA aneurysm was low. Intra-operative CT angiogram, neuro-navigation, indocyanine green video angiography (ICGV) are some of the useful tools in improving outcomes in surgical clipping of these aneurysms. Distal MCA aneurysms are less frequently encountered. Surgical clipping is the treatment of choice in these cases. Challenge arises in localising these aneurysms and adjuncts such as intraoperative CT angiogram, neuro-navigation, ICGV can be useful to overcome that challenge.","PeriodicalId":218723,"journal":{"name":"Journal of Cerebrovascular Sciences","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127733778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current techniques in the management of AVMs include observation, microsurgery, embolisation and radiosurgery, or combination therapy. AVMs are classically categorised based on the Spetzler-Martin grading and it is generally accepted that Grades I and II are best managed by microsurgical resection. To discuss the technique of astute visual inspection of AVM malformations on the operating table in microsurgical management of AVMs, and the surgical importance and significance of the valuable inferences derived from this routine. It is of utmost importance to visually distinguish between the arterial and venous ends of the nidus, and this can be effectively accomplished through eyeballing techniques by looking at the appearance of the vessels and noticing its colour, thickness, and underlying blood; and the variations in the turgor pressure of the nidus with changes in compression of the arterial and venous ends. It is equally important to visually identify the safe and effective plane to approach the target lesion by identifying the gliotic plane, the discoloured vertex of the underlying haematoma, or the widened subarachnoid spaces. Microsurgical resection is a definite mode of treatment of intra-cranial AVMs and flawless execution of surgery is vital. Eyeballing techniques must be aimed at correctly identifying the nature of the lesion and creating a mind-map before setting out to manipulate the AVM. A good initial visual inspection and survey is a crucial measure of safety and efficiency in AVM surgery.","PeriodicalId":218723,"journal":{"name":"Journal of Cerebrovascular Sciences","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129528297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in 10% of the population, they get blood supply from the internal carotid artery via a posterior communicating artery. This variant is called as fetal type of PCA (fPCA). Whether fPCA is an anatomical variant or a predisposing factor for a cerebrovascular event remains an enigma. Aims: The aim is to assess if fPCA is associated with increased risk of ischaemic stroke or other vascular anomalies. Settings and Design: It is a retrospective cross-sectional observational study. Subjects and Methods: Patients who underwent MR or CT angiography, over 5 years for various neurological illnesses were screened for fPCA. Those patients were assessed for vascular anomalies and ischaemic stroke. Statistical Analysis Used: Chi-square in the Statistical Package for the Social Sciences v23. Results: On analysis of 250 patients, five had aneurysms; three had AV malformation, one with Fenestration and one with vascular loop. And 51% were found to have an ischaemic stroke, in which 34% had large vessel disease, 41% had lacunar infarct, 7% had a cardioembolic stroke and 18% had an embolic stroke of unknown source with predominantly middle cerebral artery territory infarct (55%). Among 127 patients with ischaemic stroke, 45% had infarcts ipsilateral to fPCA vs 28% on the opposite side of fPCA. Conclusions: We conclude that patients with fPCA had increased risk of MCA infarct probably due to poor collaterals from posterior circulation and fPCA is not associated with increased risk of aneurysms or AV malformations.","PeriodicalId":218723,"journal":{"name":"Journal of Cerebrovascular Sciences","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134414808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Balloons and stents are used to assist in coiling the wide-neck aneurysms, but these are associated with increased intra-procedure and peri-procedure risk in ruptured aneurysms. Microcatheter-assisted coiling (MAC) is an alternative salvage technique in these situations which is under reported. Materials and Methods: We describe our experience in a cohort of 16 patients with ruptured wide neck aneurysm treated with MAC technique. Our primary objective of intervention in acute setting was to secure the aneurysm to prevent rebleed. Results: Anterior communicating artery aneurysm was the most common (56.3%) followed by middle cerebral artery bifurcation aneurysm (18.8%), paraclinoid aneurysm (12.5%), posterior communicating artery aneurysm (6.3%) and basilar tip aneurysm (6.3%). Mean greatest dimension of dome and neck were 8.9 mm and 4.6 mm, respectively. Mean neck to dome ratio was 1.8. Fisher grade 3 and grade 4 subarachnoid haemorrhage (SAH) were observed in 56.3% and 43.7% patients, respectively. Immediate post-procedure digital subtraction angiography (DSA) showed Raymond Roy grade 1, grade 2 and grade 3 embolisation in 62.5%, 33.3% and 6.7% patients, respectively. No distal embolus, vessel occlusion, vessel perforation or aneurysm rupture was observed. Immediate post-procedure DSA showed good distal flow in all patients. Infarct was observed at 24 and 48 hours respectively, in two patients with Fisher Grade 3 SAH. Conclusion: Ruptured wide neck aneurysms can be embolised with complete preservation of branching vessel and distal flow. Total occlusion can be achieved in 2/3rd of patients.","PeriodicalId":218723,"journal":{"name":"Journal of Cerebrovascular Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128615989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present two cases of bilateral CCF – one secondary to trauma and other occurred spontaneously. Both the patients presented with the signs of raised intraocular pressure – decreased vision, chemosis, proptosis and ophthalmoplegia. Magnetic resonance imaging and digital subtraction angiography confirmed a bilateral CCF. Both the patients underwent two settings of endovascular embolisation procedures, and complete embolisation of bilateral CCF was achieved. Available literature is unclear about the aetiology of bilateral CCF, technique of endovascular embolisation and the prognosis of bilateral CCF.
