Tortuosity of the cavernous internal carotid artery (cICA) complicates neuro-endovascular access. Improved assessment cICA tortuosity could improve procedural outcomes. This study attempts to refine classification through analysis its effect on mechanical thrombectomy (MT) outcomes and externally validate previously scales. Retrospective single center review 191 patients who underwent transfemoral anterior circulation MT over 5 years. Four parameters were measured. Regression was performed...
OBJECTIVE Many low-risk unruptured intracranial aneurysms (UIAs) are followed for growth with surveillance imaging. Growth of UIAs likely increases the risk rupture. The incidence and factors UIA or de novo aneurysm formation require further research. authors retrospectively identify annual in an protocol. METHODS Over 11.5-year period, recommended imaging to 192 patients 234 UIAs. was assessed. With logistic regression, patient compliance protocol RESULTS During 621 patient-years follow-up,...
The basilar bifurcation aneurysm (BBA) is still considered to be one of the most challenging aneurysms for micro- and endovascular surgery. Classic surgical approaches, such as subtemporal, lateral supraorbital (LSO), modified presigmoid, are reliable effective.To analyze clinical radiological factors that affect selection these classic approaches their outcomes.A retrospective analysis was conducted on data from computed tomographic angiography BBA have been clipped in Department...
Introduction Analysis of computed tomography perfusion (CTP) studies before and after superficial temporal artery to middle cerebral (STA-MCA) bypass is warranted better understand steno-occlusive pathology. Methods Retrospective review was performed STA-MCA patients with disease CTP surgery. parameters were evaluated for change bypass. Results A total 29 hemispheres bypassed in 23 patients. After bypass, mean transit time (MTT) peak (TTP) improved. When analyzed as a ratio the contralateral...
BACKGROUND Cerebral arterial vasospasm is a rare complication after supratentorial meningioma resection. The pathophysiology of this condition may be similar to aneurysmal subarachnoid hemorrhage, and treatment options similar. OBSERVATIONS authors present two cases cerebral resection perform systematic literature review cases. LESSONS associated with significant morbidity due ischemia if not addressed in timely manner. Treatment paradigms adopted from the management hemorrhage.
The optimal duration for dual antiplatelet therapy (DAPT) after stent-assisted coiling (SAC) of intracranial aneurysms is unclear. Longer-term may reduce thrombotic complications but increase the risk bleeding complications.
<h3>BACKGROUND AND PURPOSE:</h3> The modified TICI score is the benchmark for quantifying reperfusion after mechanical thrombectomy. There has been limited investigation into reliability of this score. We aim to identify intra-rater and inter-rater mTICI among endovascular neurosurgeons. <h3>MATERIALS METHODS:</h3> Four independent neurosurgeons (raters) reviewed angiograms 67 patients at 2 time points. κ statistics assessed inter- intrarater compared raters'-versus-proceduralists' scores....
Occlusion of blood vessels using high-intensity focused ultrasound (HIFU) is a potential treatment for arteriovenous malformations and other neurovascular disorders. However, attempting HIFU-induced vessel occlusion can also cause rupture, resulting in hemorrhage. Possible rupture mechanisms include mechanical effects acoustic cavitation heating the wall.HIFU exposures were performed on 18 ex vivo porcine femoral arteries with simultaneous passive detection. Vessels insonified by 3.3-MHz...
<b>Background</b> One structure, the ligamentum flavum, nearly always encountered in lumbar spinal operations, has not been examined as an important anatomical landmark. In this context, we describe its relevance corridors of small surgical exposures created by minimally invasive approaches. <b>Material and Methods</b> cadaveric intraoperative dissections, introduce a systematic technique for resection ligament clarify relationships with exiting nerve roots, pedicles, facet capsule, midline...
Brain arteriovenous malformations (AVM) are commonly treated with endovascular embolization. Due to the rapid evolution of technology and lack consistent practice guidelines regarding AVM embolization, further study embolization outcomes is warranted.We conducted a retrospective review AVMs embolized at single center from 2002-2019. Patient demographics, characteristics, intention angiographic clinical outcome after were recorded. We compared results those n-butyl cyanoacrylate (n-BCA)...
