Efficacy of endovascular embolization versus microsurgical clamping in the treatment of intracranial aneurysms: a meta-analysis

Intracranial aneurysms (IA) can induce increased intracranial pressure, headache, and the development of nausea and vomiting if not treated in time, and failure to receive timely diagnosis and treatment can lead to disability or death. However, the efficacy and prognostic value of craniotomy and endovascular embolization in patients with IA remains a controversial topic. This meta-analysis systematically evaluated the efficacy of endovascular coiling versus cranial aneurysm clamping on the immediate postoperative outcome and prognosis of patients with IA. PubMed, EMBASE, and the Cochrane Library databases were searched for retrieval of relevant references. Literature was screened according to pre-defined inclusion and exclusion criteria, and data were extracted and assessed for quality. A total of 10 studies, including 2,654 cases, were included in the analysis. Among them, 1,313 cases underwent craniotomy clipping surgery (clip group), and 1,341 cases underwent endovascular coiling (coil group). The quality of the studies in 8 articles evaluated using the Newcastle-Ottawa Scale (NOS) was ≥6. Meta-analysis was conducted using Rev Man 5.3 and Stata 17 software. The results of meta-analysis showed that no significant difference in complete occlusion rate [OR=1.76, 95% CI (0.78, 3.96), P=0.17] when comparing the clip and coil group. Compared to the clip group, the coil group had a better clinical short-term outcome [OR=1.55, 95% CI (1.05, 2.27), P=0.03], but an increased rate of postoperative residual or recurrence [OR=0.40, 95% CI (0.17, 0.91), P=0.03]. In addition, there were no significance differences identified in terms of complications, including the rates of postoperative rebleeding [OR=1.60, 95% CI (0.97, 2.63), P=0.07], ischemic stroke [OR=1.12, 95% CI (0.45, 2.79), P=0.81], and cerebral vasospasm [OR=0.90, 95% CI (0.13, 6.03), P=0.91]. Subsequently, we conducted experimental sequence analysis for each indicator, and the results were consistent with the results of meta-analysis. According to the recent clinical prognosis, a funnel plot was constructed, showing significant asymmetry on both sides, indicating some publication bias. However, the results of Begg's test with P=0.734 and Egger's test with P=0.633 suggest no significant publication bias. In general, endovascular coiling and microsurgical clipping appear to be equally effective in achieving vascular occlusion. Endovascular coiling may be more effective in improving the short-term clinical outcomes for patients. However, this approach may increase the rate of postoperative residual issue or recurrence.

Analysis of Clinical Effects of Comprehensive Nursing Based on Enhanced Recovery after Surgery in Patients with Embolization for Intracranial Aneurysms

Objective. This research sets out to elucidate the clinical effect of comprehensive nursing based on the concept of enhanced recovery after surgery (ERAS) in patients with embolization for intracranial aneurysms (IAs). Methods. This study enrolled 119 patients with embolization for IAs in the Zhongnan Hospital of Wuhan University from January 2020 to January 2021 and divided them into two groups according to the perioperative care they received: a control group ( $n=39$ ) treated with routine perioperative nursing and an observation group ( $n=80$ ) treated with ERAS-based comprehensive nursing. Surgical indicators, neurological function (National Institute of Health Stroke Scale (NIHSS) score; Scandinavian Stroke Scale (SSS) score), anxiety and depression (Self-Rating Anxiety Scale (SAS) score; Self-Rating Depression Scale (SDS) score), incidence of adverse events, and patient satisfaction were compared. Results. The observation group had better surgical indicators and lower scores of NIHSS, SSS, SAS, and SDS than the control group, accompanied by a lower incidence of adverse events and higher patient satisfaction. Conclusions. ERAS-based comprehensive nursing can better promote patients’ neurological recovery after embolization for IAs, relieve unhealthy emotions (depression, anxiety, etc.), and reduce the occurrence of adverse reactions, facilitating patient discharge.
