“…Only one case of sICH was reported in this series of patients (2.2%) and apparently it was not related to the use of the Q Catheter, but rather to the evolution of infarction and massive reperfusion phenomenon 2 days after thrombectomy. The mortality rate was 13.3%, similar to that reported with other aspiration catheters (10%–22.9%) 10–16. Finally, a favorable clinical outcome at 3 months was seen in 55.6% of our patients, similar to or slightly higher than the rates observed in populations treated with other aspiration catheters (23%–61%) 10–17…”

“…First-pass mTICI 2B/3 rates for other large bore catheters like ARC,11 AXS Catalyst,12 and SOPHIA10 13 14 range from 24% to 60%, which are similar to our first-pass results (55.3%). Interestingly, overall Q Catheter results reached mTICI 2B/3 reperfusion rates superior to 65% in our series of patients.…”

“…The final successful revascularization mTICI 2B/3 rate in this series is 93.3%, comparable to the range of 84%–98% obtained by the ARC,11 AXS Catalyst,12 ACE 64/68,15 React 68,16 and SOPHIA catheters 10 13 14. Since final revascularization rates include the use of different thrombectomy devices and techniques, our results illustrate the compatibility and efficacy of the Q Catheter with other materials in order to achieve a reopening of the vessel in complicated or resistant occlusions.…”

BackgroundThe Q Aspiration Catheter (MIVI Neuro) has demonstrated greater aspiration flow rates and ingestion forces compared with conventional catheters in vitro. The safety and performance of the Q Catheter was assessed using a direct aspiration first pass technique in patients with acute ischemic stroke at four neurointerventional centers in Spain.MethodsWe included adult patients who underwent mechanical thrombectomy between March 2019 and March 2020 using the Q Catheter as first-line therapy. Performance endpoints included final successful revascularization of the target vessel (defined as modified thrombolysis in cerebral infarction (mTICI) grade 2B/3), first pass revascularization, and overall Q Catheter revascularization. Safety endpoints were symptomatic intracranial hemorrhage (sICH), embolization to new territory (ENT), and procedural complications. Modified Rankin Scale (mRS) score and all-cause mortality were also assessed.ResultsForty-five subjects were enrolled. The Q Catheter successfully navigated to the lesion in 95.5% (43/45) of patients. Final successful mTICI 2B/3 revascularization was achieved in 93.3% (42/45), first pass mTICI 2B/3 revascularization with the Q Catheter was 55.3% (21/38), and overall with Q Catheter mTICI 2B/3 revascularization was 65.8% (25/38). Favorable clinical outcome of mRS 0–2 was achieved in 55.6% (25/45). There were no cases of ENT. sICH and mortality rates were 2.2% (1/45) and 13.3% (6/45), respectively.ConclusionIn this multicenter, observational study, the Q Aspiration Catheter used as first-line therapy demonstrated a good and safe profile in terms of navigation, revascularization, and safety in patients with acute ischemic stroke.

BackgroundDirect aspiration thrombectomy is a well-established method for mechanical thrombectomy in acute ischemic stroke. Yet, the influence of aspiration catheter internal diameter (ID) on aspiration thrombectomy efficacy is incompletely understood.MethodsA systematic literature review and meta-regression analysis was completed to evaluate the impact of primary aspiration thrombectomy outcomes based on the ID of the aspiration catheter. Primary outcome measures were: final recanalization of modified Thrombolysis In Cerebral Ischemia (mTICI) 2b-3 with aspiration only and with rescue modalities, first pass effect (FPE), need for rescue modalities, intracranial hemorrhagic complication rates, and functional outcomes of 90-day modified Rankin Scale (mRS) of 0–2.Results30 studies were identified with 3228 patients. Meta-regression analysis revealed a significant association between increasing aspiration catheter ID and FPE (p=0.032), between ID and final recanalization with aspiration only (p=0.05), and between ID size and recanalization including cases with rescue modalities (p=0.002). Further, subgroup analysis indicated that catheters with an ID ≥0.064 inch had a lower rate of need for rescue than smaller catheters (p=0.013). Additionally, catheters with an ID ≥0.068 inch had a higher rate of intracranial bleeding complications (p=0.025). Lastly, no significant association was found in functional outcomes overall.ConclusionsLarger aspiration catheters are associated with a higher rate of FPE, final recanalization with only an aspiration catheter, and in cases with rescue modalities, though with a higher rate of hemorrhagic complications. These findings confirm that aspiration catheter size functions as a variable in aspiration thrombectomy, which should be considered in future study and trial design.
