Efficacy of mechanical thrombectomy in stroke patients with large vessel involvement

Differences in outcome between left-sided and right-sided mechanical thrombectomy for acute ischemic stroke: A systematic review and meta-analysis

BACKGROUND

Mechanical thrombectomy (MT) is a safe and effective treatment option for acute ischemic stroke due to large vessel occlusion. To investigate differences in outcomes between patients receiving left-sided and right-sided MT, we performed a systematic review and meta-analysis.

METHODS

A systematic literature review was performed using Embase, PubMed, Scopus, and Web of Science databases. Additional literature was searched for manually. Studies reporting safety and efficacy metrics for MT were included. Data regarding the modified Rankin scale (mRS), thrombolysis in cerebral infarction (TICI), symptomatic intracranial hemorrhage (sICH), and 90-day mortality were included. A random-effects model was used to calculate pooled odds ratios (ORs), mean differences (MDs), and 95% confidence intervals (CIs).

RESULTS

The literature search yielded 13 reports consisting of 19 studies ranging from 98 to 5590 patients. Patients presenting with left-sided stroke had a National Institutes of health stroke scale score 2.89 greater than patients presenting with right-sided stroke (MD = 2.89; 95% CI = 2.09-3.68; P-value < 0.001). There were no differences between left-sided and right-sided MT patients for mRS 0-2 (OR = 0.94; 95% CI = 0.85-1.04; P-value = 0.224), TICI 2b-3 (OR = 1.05; 95% CI = 0.88-1.25; P-value = 0.598), sICH (OR = 0.83; 95% CI = 0.61-1.14; P-value = 0.255), or 90-day mortality (OR = 1.06; 95% CI = 0.84-1.33; P-value = 0.610).

CONCLUSIONS

There does not appear to be a difference in outcomes for patients undergoing left-sided or right-sided thrombectomy.

Prevalence of Hemiplegic Shoulder Pain in Iran: A Systematic Review and Meta-analysis

Context

Hemiplegic shoulder pain (HSP) is one of the complications of a stroke.

Objectives

This study aimed to determine shoulder pain prevalence in cerebrovascular accident (CVA) patients.

Methods

This meta-analysis study searched English and Persian descriptive or descriptive-analytical full-text studies on CVA patients. The search was carried out in all databases by two researchers using keywords such as stroke, pain, CVA, hemiplegic, and shoulder pain. Data analysis was done with the software CMA3.

Results

In the initial search, 109 articles were found, and finally, the data from four articles were analyzed. The prevalence of HSP was 23% (confidence interval (CI) = 10.3% - 43.5%).

Conclusions

Considering the HSP prevalence (28.1%) among CVA patients, it is necessary to carry out rehabilitation interventions to prevent such pain in these patients. It is also suggested that rehabilitation interventions be included in the patient education of the healthcare system.
