Effectivity and safety of endovascular coiling versus microsurgical clipping for aneurysmal subarachnoid hemorrhage: A systematic review and meta-analysis

BACKGROUND

There is an ongoing lack of consensus among clinicians regarding on the optimal aneurysmal subarachnoid hemorrhage (aSAH) management approach between endovascular coiling and microsurgical clipping.

METHODS

Comprehensive literature search for randomized controlled trials (RCTs) was conducted in Medline and Cochrane databases until January 1st, 2023 without language constraints. Effectivity outcomes included one-year mortality, one-year poor outcomes, and one-year complete aneurysmal occlusion, while safety outcomes comprised the incidence of vasospasms, rebleeding, post-operative complications, and cerebral ischemia.

RESULTS

Eight RCTs, involving 3585 aSAH patients, underwent comprehensive quantitative analysis. Among them, 1792 underwent endovascular coiling and 1773 patients had microsurgical clipping. Regarding effectivity, the rates of one-year mortality (OR: 0.79, 95% CI: 0.61-1.03, p = 0.08) exhibited no significant difference. However, endovascular coiling demonstrated an inferior one-year complete aneurysmal occlusion rate (OR: 0.33, 95% CI: 0.21-0.53, p < 0.00001), although with significantly lower rates of poor outcomes (OR: 0.68, 95% CI: 0.57-0.81, p < 0.00001) compared to the microsurgical clipping group. As for safety, endovascular coiling group exhibited lower rates of vasospasm (OR: 0.58, 95% CI: 0.36-0.92, p = 0.02), post-operative complications (OR: 0.40, 95% CI: 0.23-0.71, p = 0.02), and cerebral ischemia (OR: 0.36, 95% CI: 0.20-0.63, p = 0.0004). No significant effect on the incidence of rebleeding was observed (OR: 1.09, 95% CI: 0.73-1.63, p = 0.68).

CONCLUSIONS

Endovascular coiling proves superior and safer for aSAH patients, but consideration of resources, patient condition, and surgeon preferences is crucial for selecting the optimal approach.

Mechanical thrombectomy in M1 and M2 segments of middle cerebral arteries: A meta-analysis of prospective cohort studies

BACKGROUND

Recent studies indicate that endovascular therapy is superior to intravenous thrombolysis in treating M1 segment MCA occlusions, however, the effectiveness of mechanical thrombectomy in MI vs. M2 segment occlusions is unclear.

METHODS

The meta-analysis was conducted by searching databases from January 2016 to January 2023, without language constraints. The quality of the studies was assessed using the Newcastle-Ottawa Scale. Pooled data analysis of outcomes, pre-existing medical comorbidities, and baseline scores were performed.

RESULTS

Six prospective cohort studies with 6356 patients were included (4405 vs. 1638). Patients with M2 occlusion had a significantly lower mean baseline NIHSS at admission (MD: -2.14; 95 %CI: -3.48 to -0.81; p = 0.002). Conversely, patients with M1 occlusion had a lower ASPECTS at admission score (MD: 0.29; 95 %CI: 0.00-0.59; p = 0.05). No significant difference was found between segments in terms of pre-existing medical comorbidities (OR: 0.96; 95 %CI: 0.87-1.05; p = 0.36), mortality rate at 90 days (OR: 0.88; 95 %CI: 0.76-1.02; p = 0.10), and hemorrhage occurrence within 24-hours (OR: 1.06; 95 %CI: 0.89-1.25; p = 0.53). Patients with M2 occlusion were more likely to have good outcomes after therapy (OR: 1.18; 95 %CI: 1.05-1.32; p = 0.006). Successful recanalization rates were comparatively higher among patients with an M1 occlusion (OR: 0.79; 95 %CI: 0.68-0.92; p = 0.003). Functional outcomes at 90 days are better in M2 occlusion patients, while successful recanalization rates are higher in M1 occlusion patients. No significant differences were found in mortality rates or hemorrhage incidence.

CONCLUSIONS

These results suggest that mechanical thrombectomy is a safe and effective treatment for MCA occlusions in both M1 and M2 segments.

The Association between Smartphone Addiction and Insomnia Incidence in Students of the Faculty of Medicine Udayana University Batch of 2020 during the Coronavirus Disease-19 Pandemic

BACKGROUND: The use of smartphones is increasing in the coronavirus disease (COVID-19) pandemic for various purposes, this encourages smartphone addiction. In addition, the incidence of insomnia has also increased in the pandemic era. AIM: This study was conducted to find an association between smartphone addiction and the incidence of insomnia, especially among students of the Faculty of Medicine, Udayana University. METHOD: This research is a descriptive-analytic study with the cross-sectional method, using two main questionnaires, Smartphone Addiction Scale-Short Version, and Insomnia Severity Index. Questionnaires were distributed using Google forms and then collected and analyzed using software SPSS version 25. RESULT: Overall the total research respondents with the inclusion criteria in this study amounted to 364 people. The results showed that 212 respondents (58.24%) had a high level of smartphone addiction and 152 respondents (41.76%) had a low level of smartphone addiction. In addition, 187 respondents (51.37%) experienced mild insomnia, 87 respondents (23.9%) experienced moderate insomnia, 13 respondents (3.57%) experienced severe insomnia, and 77 respondents (21.15%) did not experience insomnia. Based on the results of data analysis, it was found that smartphone addiction had a significant relationship (p = 0.002) with weak and positive correlation (r = 0.162) to the incidence of insomnia. CONCLUSION: It was found that the majority of respondents experienced high levels of smartphone addiction and mild insomnia. Another finding suggests the higher addiction to the smartphones, the more severe insomnia suffered.
