OBJECTIVES: The purpose of this research was to define the predictors of the "slow-reflow" phenomenon during carotid artery intervention with filter-type embolic protection devices (EPDs) and to determine its prognostic significance. BACKGROUND: During carotid artery intervention using filter-type EPDs, we have observed cases in which there is angiographic evidence of a significant reduction in antegrade flow in the internal carotid artery proximal to the filter device, termed "slow-flow." The predictors of this phenomenon and its prognostic significance are unknown. METHODS: Using a single-center prospective carotid intervention registry, patients with slow-flow were compared to patients with normal flow during carotid intervention with respect to clinical, procedural, and lesion characteristics, and the 30-day incidence of death and stroke. RESULTS: A total of 414 patients underwent 453 carotid artery interventions using EPDs. Slow-flow occurred in 42 patients (10.1%) undergoing 42 carotid interventions (9.3%), and most commonly occurred after post-stent balloon dilatation (71.4%). Multivariate logistic regression analysis identified the following predictors of slow-flow: recent history (<6 months) of stroke or transient ischemic attack (odds ratio [OR] 2.8, 95% confidence interval [CI] 1.4 to 5.6, p = 0.004), increased stent diameter (OR 1.4, 95% CI 1.02 to 1.94, p = 0.044), and increased patient age (OR 1.05, 95% CI 1.01 to 1.09, p = 0.025). Among patients with slow-flow, the 30-day incidence of stroke or death was 9.5% compared to 2.9% in patients with normal flow (chi-square = 4.73, p = 0.03). This difference was driven by the disparity in the 30-day incidence of stroke (9.5% vs. 1.7%). CONCLUSIONS: Slow-flow during carotid intervention with EPDs is a frequent event that is associated with an excess risk of periprocedural stroke. The association of the phenomenon with clinically symptomatic carotid lesions and use of larger stent diameters suggests that embolization of vulnerable plaque elements may play a pathogenic role. 相似文献

- Complex arch anatomy (type 2, type 3) and bovine configuration were identified in 34.4% and 20.5% of carotid stent patients, respectively.
- Catheter manipulation time (CMT), rather than arch complexity per se, was the only independent predictor of adverse events after carotid stenting.
- Careful attention to patient selection, preprocedural planning, and stent technique are important to ensure success.

Purpose:
The objective of this study was to evaluate the interrater reliability, construct validity, and sensitivity of Toronto Rehabilitation Institute–Hand Function Test (TRI-HFT), within an interventional randomized control trial.Method:
Twenty-one participants with subacute C4 to C7 spinal cord injury (SCI) were recruited. Based on randomization, participants were allocated to either the functional electrical stimulation therapy group or the conventional occupational therapy group. Baseline and follow-up assessments of participants were videotaped. For testing interrater reliability, videotaped images were transferred to DVDs that were later observed by 2 observers. Construct validity was determined by comparing total scores on TRI-HFT to self-care subscore components of the Spinal Cord Independence Measure (SCIM) and FIM. To establish sensitivity of TRI-HFT, we compared pre- and posttreatment scores on all 3 measures (ie, TRI-HFT, FIM, and SCIM).Results:
TRI-HFT was found to have high interrater reliability with an intercorrelation coefficient (ICC) of 0.98. Moderate to strong correlations were found between TRI-HFT total scores and self-care components of FIM and SCIM for both hands individually post therapy. Due to a floor effect of the FIM and SCIM, there was weak correlation between pretherapy scores of the said measures and TRI-HFT. TRI-HFT was found to be highly sensitive in determining difference in function pre and post therapy.Conclusions:
This study demonstrated that the TRI-HFT is a reliable and sensitive measure to assess unilateral hand gross motor function in persons with tetraplegia, with moderate to strong construct validity. 相似文献109.
