1Updates in the management of cranial dural arteriovenous fistula显示文摘Dural arteriovenous fistula(dAVF)accounts for approximately 10%of all intracranial vascular malformations.While they can be benign lesions,the presence of retrograde venous drainage and cortical venous reflux makes the natural course of these lesions aggressive high risk of haemorrhage,neurological injury and mortality.Endovascular treatment is often the first line of treatment for dAVF.Both transarterial and transvenous approaches are used to cure dAVF.The selection of treatment approach depends on the angioarchitecture of the dAVF,the location,the direction of venous flow.Surgery and,to a lesser extent,stereotactic radiosurgery are used when endovascular approaches are impossible or unsuccessful.Humain Baharvahdat Yinn Cher Ooi Wi Jin Kim Ashkan Mowla Alexander L Coon Geoffrey P Colby 2020Stroke & Vascular Neurology2020,5,1:10

4Procedural complexity independent of P2Y12 reaction unit(PRU)values is associated with acute in situ thrombosis in Pipeline flow diversion of cerebral aneurysms显示文摘background Acute in situ thrombosis is an ischaemic phenomenon during Pipeline embolisation device(PED)procedures with potentially high morbidity and mortality.There is controversy regarding the role of platelet function testing with P2Y12 assay as a predictor of intraprocedural thromboembolic events.There is limited knowledge on whether procedural complexity influences these events.Methods Data were collected retrospectively on 742 consecutive PED cases at a single institution.Patients with intraprocedural acute thrombosis were compared with patients without these events.results A cohort of 37 PED cases with acute in situ thrombosis(mean age 53.8 years,mean aneurysm size 8.4 mm)was matched with a cohort of 705 PED cases without intraprocedural thromboembolic events(mean age 56.4 years,mean aneurysm size 6.9 mm).All patients with in situ thrombosis received intra-arterial and/or intravenous abciximab.The two groups were evenly matched in patient demographics,previous treatment/subarachnoid hemorrhage(SAH)and aneurysm location.There was no statistical difference in postprocedural P2Y12 reaction unit(PRU)values between the two groups,with a mean of 156 in the in situ thrombosis group vs 148 in the control group(p=0.5894).Presence of cervical carotid tortuosity,high cavernous internal carotid artery grade,need for multiple PED and vasospasm were not significantly different between the two groups.The in situ thrombosis group had statistically significant longer fluoroscopy time(60.4 vs 38.4 min,p<0.0001),higher radiation exposure(3476 vs 2160 mGy,p<0.0001),higher rates of adjunctive coiling(24.3% vs 8.37%,p=0.0010)and higher utilisation of balloon angioplasty(37.8% vs 12.2%,p<0.0001).Clinically,the in situ thrombosis cohort had higher incidence of major and minor stroke,intracerebral haemorrhage and length of stay.Conclusions Predictors of procedural complexity(higher radiation exposure,longer fluoroscopy time,adjunctive coiling and need for balloon angioplasty)are associated with acute thrombotic events during PED placement,independent of PRU values.Bowen Jiang Matthew T Bender Erick M Westbroek Jessica K Campos Li-Mei Lin Risheng Xu Rafael J Tamargo Judy Huang Geoffrey P Colby Alexander L Coon 2018Stroke & Vascular Neurology2018,3,3:2
