Hyper-attenuating brain lesions on CT after ischemic stroke and thrombectomy are associated with final brain infarction.
Conclusions Hyper-attenuating lesions on head NCCT scans performed after endovascular treatment of AIS may predict final brain infarcted areas. The prediction appears to be higher in the deep brain regions compared with the cortical regions. PMID: 28950737 [PubMed - as supplied by publisher]

Flat-panel dual-energy head computed tomography in the angiography suite after thrombectomy for acute stroke: A clinical feasibility study
CONCLUSION: We demonstrate that intra-procedural DE-CBCT after thrombectomy is feasible and provides clinically meaningful images. There was close agreement between findings on DE-CBCT and standard DECT. Our findings suggest that DE-CBCT could be used in the future to improve stroke thrombectomy patient workflow and to more efficiently guide the postoperative management of these patients.PMID:36788203 | DOI:10.1177/15910199231157462

ASPECTS evolution after endovascular successful reperfusion in the early and extended time window
CONCLUSION: ASPECTS evolution is a strong predictor of functional and safety outcomes after successful endovascular therapy. Higher number of EVT attempts and incomplete reperfusion are associated with ASPECTS evolution at day 1.PMID:37671452 | DOI:10.1177/15910199231196953

Evaluation of pure subarachnoid hemorrhage after mechanical thrombectomy in a series of 781 consecutive patients
CONCLUSION: We suggest that dual-energy computed tomography could better distinguish between blood and pure contrast stagnation. Still, SAH was not associated with an unfavorable outcome in stroke patients undergoing thrombectomy.PMID:36916147 | DOI:10.1177/15910199231163046

Contrast extravasation after angioplasty for symptomatic stenosis of the middle cerebral artery: A case report.
Authors: Wang X, Yang B, Zhu H, Jiao L Abstract Contrast extravasation is a common phenomenon in acute ischaemic stroke patients who are treated with endovascular therapy, but it is rarely reported in selective angioplasty of intracranial artery stenosis. In this case we present the treatment and follow-up studies of a patient with severe stenosis in the M1 segment of the middle cerebral artery. We observed extravasation of contrast medium in the brain tissue around the stent after the operation by a computed tomography scan taken immediately, but the patient did not experience any neurological deficits during the ...
