First Pass

BackgroundFirst-pass effect (FPE), restoring complete or near complete reperfusion (modified Thrombolysis in Cerebral Infarction (mTICI) 2c-3) in a single pass, is an independent predictor for good functional outcomes in the endovascular treatment of acute ischemic stroke. The economic implications of achieving FPE have not been assessed.ObjectiveTo assess the economic impact of achieving complete or near complete reperfusion after the first pass.MethodsPost hoc analyses were conducted using ARISE II study data. The target population consisted of patients in whom mTICI 2c–3 was achieved, stratified into two groups: (1) mTICI 2c–3 achieved after the first pass (FPE group) or (2) after multiple passes (non-FPE group). Baseline characteristics, clinical outcomes, and healthcare resource use were compared between groups. Costs from peer-reviewed literature were applied to assess cost consequences from the perspectives of the United States (USA), France, Germany, Italy, Spain, Sweden, and United Kingdom (UK).ResultsAmong patients who achieved mTICI 2c–3 (n=172), FPE was achieved in 53% (n=91). A higher proportion of patients in the FPE group reached good functional outcomes (90-day modified Rankin Scale score 0–2 80.46% vs 61.04%, p<0.01). The patients in the FPE group had a shorter mean length of stay (6.10 vs 9.48 days, p<0.01) and required only a single stent retriever, whereas 35% of patients in the non-FPE group required at least one additional device. Driven by improvement in clinical outcomes, the FPE group had lower procedural/hospitalization-related (24–33% reduction) and annual care (11–27% reduction) costs across all countries.ConclusionsFPE resulted in improved clinical outcomes, translating into lower healthcare resource use and lower estimated costs.

First Pass

Background and Purpose: Achieving complete revascularization after a single pass of a mechanical thrombectomy device (first pass effect [FPE]) is associated with good clinical outcomes in patients with acute ischemic stroke due to large vessel occlusion. We assessed patient characteristics, outcomes, and predictors of FPE among a large real-world cohort of patients (Systematic Evaluation of Patients Treated with Stroke Devices for Acute Ischemic Stroke registry). Methods: Demographics, clinical outcomes, and procedural characteristics were analyzed among patients in whom FPE (modified Thrombolysis in Cerebral Infarction 2c/3 after first pass) was achieved versus those requiring multiple passes (MP). Modified FPE and modified MP included patients achieving modified Thrombolysis in Cerebral Infarction 2B-3. Primary outcomes included 90-day modified Rankin Scale (mRS) score and mortality. Results: Among 984 Systematic Evaluation of Patients Treated with Stroke Devices for Acute Ischemic Stroke patients, 930 had complete 90-day follow-up. FPE was achieved in 40.5% (377/930) of patients and MP in 20.0% (186/930). Baseline characteristics were similar across all groups. The FPE group had fewer internal carotid artery occlusions compared with MP ( P =0.029). The FPE group had faster puncture to recanalization time ( P ≤0.001), higher rates of 90-day mRS score of 0 to 1 (52.6% versus 38.6%, P =0.003), mRS score of 0 to 2 (65.4% versus 52.0%, P =0.003), and lower 90-day mortality compared with the MP group (12.0% versus 18.7%, P =0.038). Similarly, compared with modified MP patients, the modified FPE group had fewer internal carotid artery occlusions ( P =0.004), faster puncture to recanalization time ( P ≤0.001), and higher rates of 90-day mRS score of 0 to 1 ( P =0.002) and mRS score of 0 to 2 ( P =0.003). Conclusions: Our findings demonstrate that FPE and modified FPE are associated with superior clinical outcomes.

The Impact

Background: Mechanical thrombectomy (MT) has significantly improved outcomes of acute ischemic stroke (AIS) patients due to large vessel occlusion (LVO). The first-pass effect (FPE), defined as achieving complete reperfusion (mTICI3/2c) with a single pass, was reported to be associated with higher functional independence rates following EVT and has been emphasized as an important procedural target. We compared MT outcomes in patients who achieved FPE to those who did not in a real world large database. Method: A retrospective analysis of LVO pts who underwent MT from a single center prospectively collected database. Patients were stratified into those who achieved FPE and non-FPE. The primary outcome (discharge and 90 day mRS 0-2) and safety (sICH, mortality and neuro-worsening) were compared between the two groups. Results: Of 580 pts, 261 (45%) achieved FPE and 319 (55%) were non-FPE. Mean age was (70 vs 71, p=0.051) and mean initial NIHSS (16 vs 17, p=0.23) and IV tPA rates (37% bs 36%, p=0.9) were similar between the two groups. Other baseline characteristics were similar. Non-FPE pts required more stenting (15% vs 25%, p=0.003), and angioplasty (19% vs 29%, p=0.01). The FPE group had significantly more instances of discharge (33% vs 17%, p<0.001), and 90-day mRS score 0-2 (29% vs 20%, p<0.001), respectively. Additionally, the FPE group had a significant lower mean discharge NIHSS score (12 vs 17, p<0.001). FPE group had better safety outcomes with lower mortality (14.2% vs 21.6%, p=0.03), sICH (5.7% vs 13.5, p=0.004), and neurological worsening (71.3% vs 78.4%, p=0.02), compared to the non-FPE group. Conclusion: Patients with first pass complete or near complete reperfusion with MT had higher functional independence rates, reduced mortality, symptomatic hemorrhage and neurological worsening. Improvement in MT devices and techniques is vital to increase first pass effect and improve clinical outcomes.

A New Technique

BackgroundThe development of new revascularization devices has improved recanalization rates and time, but not clinical outcomes. We report a prospectively collected clinical experience with a new technique utilizing a direct aspiration first pass technique with large bore aspiration catheter as the primary method for vessel recanalization.Methods98 prospectively identified acute ischemic stroke patients with 100 occluded large cerebral vessels at six institutions were included in the study. The ADAPT technique was utilized in all patients. Procedural and clinical data were captured for analysis.ResultsThe aspiration component of the ADAPT technique alone was successful in achieving Thrombolysis in Cerebral Infarction (TICI) 2b or 3 revascularization in 78% of cases. The additional use of stent retrievers improved the TICI 2b/3 revascularization rate to 95%. The average time from groin puncture to at least TICI 2b recanalization was 37 min. A 5MAX demonstrated similar success to a 5MAX ACE in achieving TICI 2b/3 revascularization alone (75% vs 82%, p=0.43). Patients presented with an admitting median National Institutes of Health Stroke Scale (NIHSS) score of 17.0 (12.0–21.0) and improved to a median NIHSS score at discharge of 7.3 (1.0–11.0). Ninety day functional outcomes were 40% (modified Rankin Scale (mRS) 0–2) and 20% (mRS 6). There were two procedural complications and no symptomatic intracerebral hemorrhages.DiscussionThe ADAPT technique is a fast, safe, simple, and effective method that has facilitated our approach to acute ischemic stroke thrombectomy by utilizing the latest generation of large bore aspiration catheters to achieve previously unparalleled angiographic outcomes.

Study Results

Background: Ostomy seals are an accessory product used to enhance the fit of an ostomy skin barrier. Research into the clinical and health economic impact of ostomy seals is limited. Aims: To evaluate the clinical and economic impact of two commercially available ostomy seals when used on patients with a newly created stoma, 1–2 days postoperatively. Methods: A non-powered, exploratory, multi-centre, two-country, open-label, parallel-randomised clinical study was conducted. Patients were randomised to the Dansac TRE Seal (Dansac A/S, Fredensborg, Denmark) or the Coloplast Brava Protective Seal (Coloplast A/S, Humlebæk, Denmark) and were followed up to 9 weeks after the stoma was created. Clinical outcomes were primarily assessed via the validated Pittman Ostomy Complication Severity Index (OCSI). Economic outcomes were assessed via the collection of stoma-related healthcare resource use. Satisfaction measures with seal performance were also collected. Findings: In total, 42 participants were enrolled (20 TRE and 22 Brava). Lower peristomal skin complication (PSC) incidence (TRE 50.0% vs Brava 72.7%; p=.16), greater PSC resolution (TRE 70.0% vs Brava 43.8%; p=.22) and slightly less severe peristomal and stomal complications (average OCSI score TRE 2.2 vs Brava 3.4; p=.19) were observed in the TRE group. On average, participants in the TRE group used 1.3 seals per day compared with 1.4 seals per day for those in the Brava group (p=.83). Lastly, 100% of clinicians and 100% of patients reported positive satisfaction with the overall performance of TRE and Brava seals. Conclusions: Participants randomised to TRE seal were observed to have lower PSC incidence, greater PSC resolution and slightly less severe peristomal and stomal complications relative to participants using the Brava seal. No substantive differences were found in stoma-related healthcare resource use. Positive satisfaction was noted for both ostomy seals. Study results provided valuable insights into the postoperative use of ostomy seals for individuals with newly created ostomies.
