“…Another series of 41 patients in which the Catch Mini retriever (BALT, Irvine, California, USA) was used in distal vessels (including M2, M3, ACA, and PCA) reported a final mTICI 2b–3 reperfusion rate of 78%. The highest recanalization rate was for M2 (82%), and one patient (2%) developed a parenchymal hematoma 10. This is similar to our 85% rate of final mTICI 2b–3 with the 3 mm Trevo.…”

“…While first-pass reperfusion has been associated with less disability,17 we were unable to show a difference in clinical outcome. This presumably relates to the heterogeneity of tissue at-risk eloquence across subjects, variability of volume of tissue at risk, and type of occlusion at presentation (isolated distal occlusion vs distal occlusion in the setting of a concomitant larger vessel/proximal occlusion vs emboli to the same or new territory) 7–13 18. In proximal occlusions, collateral strength has been demonstrated to be inversely associated with NIHSS and directly associated with improved reperfusion rates 19.…”

“…Although aspiration and stent retriever mechanical thrombectomy (MT) perform similarly in proximal occlusions, data on more distal occlusions are limited 5 6. The 3×20 mm Trevo Retriever (3 mm Trevo) and the Penumbra 3MAX reperfusion catheter have been reported in distal occlusions with good reperfusion rates and low safety concerns 7–13. However, the optimal approach for distal intracranial occlusions in thrombectomy for AIS is unclear since no comparative data are available.…”

BackgroundAlthough aspiration and stent retriever thrombectomy perform similarly in proximal occlusions, no comparative series are available in distal occlusions. We aimed to compare the 3 mm Trevo Retriever against the 3MAX thromboaspiration catheter in distal arterial occlusions.MethodsA single-center retrospective review of a prospectively maintained databank for patients treated with the 3 mm Trevo stent retriever or 3MAX thromboaspiration as the upfront approach for distal occlusions (middle cerebral artery mid/distal M2/M3, anterior cerebral artery A1/A2/A3 or posterior cerebral artery P1/P2) from January 2014 to July 2018 was performed. The primary outcome was the rate of distal occlusion first-pass reperfusion (modified Thrombolysis in Cerebral Infarction (mTICI) 2b–3).ResultsOf 1100 patients treated within the study period, 137 patients/144 different arteries were treated with the 3 mm Trevo (n=92) or 3MAX device (n=52). The groups had comparable demographics and baseline characteristics. There was a higher rate of first-pass mTICI 2b–3 reperfusion (62% vs 44%; p=0.03), a trend towards a higher rate of final mTICI 2b–3 reperfusion (84% vs 69%; p=0.05), and lower use of adjuvant therapy (15% vs 31%; p=0.03) with the 3 mm Trevo compared with the 3MAX. The median number of passes (p=0.46), frequency of arterial spasm (p=1.00), rates of parenchymal hematomas (p=0.22)/subarachnoid hemorrhage (p=0.37) in the territory of the approached vessel were similar across the two groups. The 90-day rate of good outcomes (45% vs 46% in the 3 mm Trevo and 3MAX groups, respectively; p=0.84) was comparable. Multivariable regression identified baseline NIH Stroke Scale (NIHSS) score (OR 0.9; 95% CI 0.8 to 0.97; p<0.01) and use of 3 mm Trevo (OR 2.2; 95% CI 1.1 to 4.6; p=0.02) independently associated with first-pass mTICI 2b–3 reperfusion.ConclusionsIn the setting of distal arterial occlusions, the 3 mm Trevo may lead to higher rates of first-pass reperfusion than direct 3MAX thromboaspiration. Lower NIHSS was found to be associated with improved reperfusion rates as observed in more proximal lesions. Further studies are warranted.

“…Recently proposed techniques such as blind exchange mini-pinning ( 11 ), in which the aspiration catheter is advanced introduced over the bare pusher wire once the stent-retriever is deployed, can circumvent problems related to catheter length and, at the same time, provide effective aspiration during the retrieval process. Techniques and specific tools for medium-sized arteries, such are mini stent-retrievers, are under development ( 17 , 23 ); thus, it can be expected that more data on the safety and efficacy of these techniques will emerge soon.…”

Background: Endovascular treatment (EVT) for stroke due to medium vessel occlusion (MeVO) can be technically challenging. Devices and tools are rapidly evolving. We aimed to gain insight into preferences and global perspectives on the usage of endovascular tools in treating MeVOs.Methods: We conducted an international survey with seven scenarios of patients presenting A3, M2/3, M3, M3/4, or P2/3 occlusions. Respondents were asked for their preferred first-line endovascular approach, and whether they felt that the appropriate endovascular tools were available to them. Answers were analyzed by occlusion location and geographical region of practice, using multinomial/binary logistic regression.Results: A total of 263 neurointerventionists provided 1836 responses. The first-line preferences of physicians were evenly distributed among stent-retrievers, combined approaches, and aspiration only (33.2, 29.8, and 26.8%, respectively). A3 occlusions were more often treated with stent-retrievers (RR 1.21, 95% CI: 1.07–1.36), while intra-arterial thrombolysis was more often preferred in M3 (RR 2.47, 95% CI: 1.53–3.98) and M3/4 occlusions (RR 7.71, 95% CI: 4.16–14.28) compared to M2/3 occlusions. Respondents who thought appropriate tools are currently not available more often chose stent retrievers alone (RR 2.07; 95% CI: 1.01–4.24) or intra-arterial thrombolysis (RR 3.35, 95% CI: 1.26–8.42). Physicians who stated that they do not have access to optimal tools opted more often not to treat at all (RR 3.41, 95% CI: 1.11–10.49). Stent-retrievers alone were chosen more often and contact aspiration alone less often as a first-line approach in Europe (RR 2.12, 95% CI: 1.38–3.24; and RR 0.49, 95% CI 0.34–0.70, respectively) compared to the United States and Canada.Conclusions: In EVT for MeVO strokes, neurointerventionalists choose a targeted vessel specific first-line approach depending on the occlusion location, region of practice, and availability of the appropriate tools.

“…Clot removal failure is usually due to the presence of an organized large, clot. In such instance the stent does not penetrate the clot, but remains compressed between the clot and the vessel wall and during the retrieval, the device slides beside it without retrieving it [14][15][16][17][18][19]. The penetration of the struts within the clot is promoted by device radial force and large openings between device filaments [20].…”
