Abstract BACKGROUND Although extremely rare, acute bilateral large vessel occlusion (LVO) is a morbid condition that requires prompt intervention. OBJECTIVE To report the technique used to achieve recanalization of bilateral internal carotid artery (ICA) terminus occlusions. METHODS This is a case of bilateral ICA terminus occlusions managed with simultaneous bilateral thrombectomies with poor collateral circulation. RESULTS Recanalization of bilateral ICA with thrombolysis in cerebral infarction (TICI) grade 0 to left TICI 2b flow with distal left A1 occlusion and right TICI 3 flow was achieved in 32 min with the use of simultaneous catheterization and aspiration thrombectomies. CONCLUSION The described technique offers an efficient and feasible means to reduce time to recanalization and radiation in cases of bilateral LVO.

Aspiration Technique

Context: Stroke is one of the main leaders of death and disability in the world. Currently, mechanical thrombectomy with stent retrievers is the technique of choice for large vessel occlusion, however, the primary aspiration technique has been proposed as a fast and safe alternative. Case report: J.E.M, male, 57 years old, hypertensive, atrial fibrillation. Started claudication of neurological deficits, with intermittent paresthesia in left upper limb for 2 days. Admitted with NIHSS 2 (nasolabial sulcus erasure and hypoesthesia in LUL), in thrombolysis window, has seen in cerebral and neck angiotomography critical stenosis of the internal carotid artery and in CT scan with perfusion Mismatch volume 72 ml and infinite ratio. Since the patient did not have sufficient criteria for thrombolysis and since the clinical prognosis was unfavorable, a diagnostic arteriography was indicated, which showed ICAR stenosis 90%. The patient proceeded with angioplasty and stenting using the ADPAT technique and mechanical thrombectomy due to occlusion in segment M1 with total recanalization (TICI 3) and NIHSS after and at discharge of 0. Conclusion: The advent of thrombectomy impacts the improvement of functional dependence and the reduction of mortality, especially in stroke with large vessel occlusion, whose treatment with thrombolytic therapy only has a low chance of recanalization.

Intravenous Alteplase

Background and Purpose: Recent trials showed thrombectomy alone was comparable to bridging therapy in patients with anterior circulation large vessel occlusion eligible for both intravenous alteplase and endovascular thrombectomy. We performed this study to examine whether occlusion site modifies the effect of intravenous alteplase before thrombectomy. Methods: This is a prespecified subgroup analysis of a randomized trial evaluating risk and benefit of intravenous alteplase before thrombectomy (DIRECT-MT [Direct Intra-Arterial Thrombectomy in Order to Revascularize AIS Patients With Large Vessel Occlusion Efficiently in Chinese Tertiary Hospitals]). Among 658 randomized patients, 640 with baseline occlusion site information were included. The primary outcome was the score on the modified Rankin Scale at 90 days. Multivariable ordinal logistic regression analysis with an interaction term was used to estimate treatment effect modification by occlusion location (internal carotid artery versus M1 versus M2). We report the adjusted common odds ratio for a shift toward better outcome on the modified Rankin Scale after thrombectomy alone compared with combination treatment adjusted for age, the National Institutes of Health Stroke Scale score at baseline, the time from stroke onset to randomization, the modified Rankin Scale score before stroke onset, and collateral score per the DIRECT-MT statistical analysis plan. Results: The overall adjusted common odds ratio was 1.08 (95% CI, 0.82–1.43) with thrombectomy alone compared with combination treatment, and there was no significant treatment-by-occlusion site interaction ( P =0.47). In subgroups based on occlusion location, we found the following adjusted common odds ratios: 0.99 (95% CI, 0.62–1.59) for internal carotid artery occlusions, 1.12 (95% CI, 0.77–1.64) for M1 occlusions, and 1.22 (95% CI, 0.53–2.79) for M2 occlusions. No treatment-by-occlusion site interactions were observed for dichotomized modified Rankin Scale distributions and successful reperfusion (extended thrombolysis in Cerebral Infarction score ≥2b) before thrombectomy. Differences in symptomatic hemorrhage rate were not significant between occlusion locations (internal carotid artery occlusion: 7.02% in bridging therapy versus 7.14% for thrombectomy alone, P =0.97; M1 occlusion: 5.06% versus 2.48%, P =0.22; M2 occlusion: 9.09% versus 4.76%; P =0.78). Conclusions: In this prespecified subgroup of a randomized trial, we found no evidence that occlusion location can inform intravenous alteplase decisions in endovascular treatment eligible patients directly presenting at endovascular treatment capable centers. Future studies are needed to confirm our findings. REGISTRATION: URL: https://www.clinicaltrials.gov ; Unique identifier: NCT03469206.

Background and purpose Cervical internal carotid artery (ICA) tortuosity is thought to impede distal catheterization during attempted mechanical thrombectomy in patients with acute ischemic stroke. This study sought to assess the morphologic characteristics of ICAs and the effects of tortuosity on thrombectomy attempts. Methods A retrospective review was completed of neck CTAs of patients with acute ischemic stroke due to a large vessel occlusion that underwent attempted endovascular recanalization. Significant tortuosity of ICAs was defined as the presence of kink(s) (acute (<90°) angulation), loop(s) (C- or S-shaped curvature with 2+ areas of acute (<90°) angulation), or coil(s) (full 360° turn arterial bend). Findings were statistically compared to procedure time, successful recanalization rate, patient demographics, and co-morbidities. Results Of 120 included patients, 47 (39.2%) had some form of tortuosity of one or both ICAs. Twenty-eight patients (23.3%) had a kink of one or both ICAs; this was followed in frequency by loops (n = 20; 16.7%) and coils (n = 8; 6.7%). Kinks were associated with lower rates of successful recanalization (p = 0.02). The presence of any tortuosity (kinks, loops, or coils) was not associated with number of passes during thrombectomy (p = 0.88), successful recanalization (p = 0.11), or total procedure time (p = 0.22). No association was noted between the presence of tortuosity and age (p = 0.96) or prior or current tobacco use (p = 0.75 and p = 0.69, respectively). Conclusion Among patients referred for urgent revascularization for large vessel occlusion, approximately 40% exhibit some tortuosity. Kinks may portend lower likelihood of recanalization success, although tortuosity as a whole seems to have little effect on endovascular thrombectomy.

Abstract INTRODUCTION Thrombectomy for large vessel occlusion (LVO) has become a well-established treatment for acute stroke. Management of tandem internal carotid artery (ICA) stenosis in thrombectomy patients can be challenging, as no formal treatment algorithm exists for this unique pathology. We present a single institution's experience with the acute treatment of ICA stenosis during or after thrombectomy with either carotid artery stent (CAS) or carotid endarterectomy (CEA). METHODS A retrospective analysis was performed on all patients who underwent thrombectomy with tandem ICA stenosis at our institution. All demographic, stroke presentation, stroke treatment, cervical carotid stenosis treatment, and follow-up data were analyzed for these patients. RESULTS From 2015 to 2018, 31 patients with tandem ICA stenosis underwent thrombectomy for LVO. Of these patients, 26 had a CAS placed, 25 of which were done at time of thrombectomy, and 1 placed 5 d after thrombectomy. CAS patients were placed on antiplatelet therapy after stent placement. Of the 25 patients who had CAS placed at time of thrombectomy, 5 patients had a symptomatic ICH, 4 of which did not survive the hospitalization. Two additional CAS patients did not survive hospitalization. There were 5 patients who had a CEA performed during the same hospital stay, ranging from 1 to 10 d post-thrombectomy. Patients who underwent CEA had a smaller area of infarct and a shorter thrombectomy procedure time when compared to the CAS patients, and all CEA patients survived hospitalization, with good outcomes. CONCLUSION CAS placement for tandem ICA stenosis at time of thrombectomy may be less safe than previously published. Early, but not simultaneous, intervention on cervical ICA stenosis after thrombectomy allows for the assessment of infarct volume, patient recovery, and the presence of intracerebral hemorrhage, and thus provides the opportunity to appropriately select patients who would benefit from treatment of the carotid stenosis with either CAS or CEA.

Carotid Blowout Syndrome

Carotid blowout syndrome (CBS) is a fatal complication of head and neck cancer. Endovascular treatment, particularly deconstructive embolization, is effective for CBS, but it might result in thromboembolic events. We report the case of a 57-year-old man with underlying recurrent head and neck cancer who had CBS. The patient received endovascular embolization of the right internal, external, and common carotid arteries. Right internal carotid artery to middle cerebral artery embolic occlusion was noted immediately after the procedure, and left-sided weakness and facial palsy were found. Ipsilateral suprabulbar cervical internal carotid artery puncture was performed under fluoroscopic guidance, and rescue suction thrombectomy was successful. The patient had no significant neurological sequela. Transcarotid intraarterial thrombectomy is a reasonable method for managing postembolization large vessel occlusion, even in the neck, after irradiation.

The authors demonstrate the use of an endovascular plug in securing a carotid artery pseudoaneurysm in an emergent setting requiring craniotomy for a concurrent subdural empyema.They describe the case of a 14-year-old boy with sinusitis and bifrontal subdural empyema who underwent transsphenoidal exploration at an outside hospital. An injury to the right cavernous segment of the ICA caused torrential epistaxis. Bleeding was successfully controlled by inflating a Foley balloon catheter within the sphenoid sinus, and the patient was transferred to the authors’ institution. Emergent angiography showed a dissection of the right cavernous carotid artery, with a large pseudoaneurysm projecting into the sphenoid sinus at the site of arterial injury. The right internal carotid artery was obliterated using pushable coils distally and an endovascular plug proximally. The endovascular plug enabled the authors to successfully exclude the pseudoaneurysm from the circulation. The patient subsequently underwent an emergent bifrontal craniotomy for evacuation of a left frontotemporal subdural empyema and exenteration of both frontal sinuses. He made a complete neurological recovery.Endovascular large-vessel sacrifice, obviating the need for numerous coils and antiplatelet therapy, has a role in the setting of selected acute neurosurgical emergencies necessitating craniotomy. The endovascular plug is a useful adjunct in such circumstances as the device can be deployed rapidly, safely, and effectively.

Background: Endovascular treatment (EVT) is a widely proven method to treat patients diagnosed with intracranial large vessel occlusion (LVO). Through this method of treatment, it has been hypothesized that a lower number of thrombectomy passes is an indicator of higher rates of modified Thrombolysis in Cerebral Infarction 2b-3 (mTICI) and favorable outcomes defined as modified Rankin Scale 0-2 (mRS). Methods: Through the utilization of a prospectively collected endovascular database between 2012-2020, variables such as demographics, co-morbid conditions, intracerebral hemorrhage, mass effect, mortality rate, and good/poor outcomes in regard to mTICI score and mRS assessment at discharge were examined. The outcomes between patients receiving EVT who were treated with < 3 thrombectomy passes or ≥ 3 passes were compared. Results: Out of 454 patients treated with mechanical thrombectomy of qualifying intracranial internal carotid artery or middle cerebral artery occlusion, site of occlusion (internal carotid artery, M1 and M2), a total of 372 (81.9%) were treated with < 3 thrombectomy passes (average age 70.34 ± 13.75 years, 46.0% women), and 82 (18.1%) were treated with ≥ 3 thrombectomy passes (average age 70.30 ± 13.72 years, 48.8% women). Significantly higher rates of mass effect (p=0.043), mRS score 3-6 (p=0.029), and mortality (p=0.025) were noted in patients treated with ≥ 3 thrombectomy passes. Further analysis revealed that patients presenting 6-24 hours from symptom onset had significantly lessened chance of effective recanalization (TICI 2B-3; p=0.021). Conclusion: A higher number of thrombectomy passes, characterized as ≥ 3 passes in this study, was associated with significantly worsened patient outcome in regard to functional outcome, and mortality. Further research is required to determine whether the number of thrombectomy passes is an accurate indicator of treatment outcome and whether delayed presentation time increases risk of poor outcome.
