Review
INTRODUCTION
Favorable midterm outcomes have been reported with the use of low-profile endografts (LPE), but long-term data is still needed. Furthermore, it is unclear if each of these LPE may have advantages over the other, which may, in turn, affect the outcomes. We systematically reviewed the literature about complications and reintervention rates of patients submitted to endovascular aneurysm repair (EVAR) of abdominal aortic aneurysm (AAA) using LPE.
MATHERIALS AND METHODS
A literature search was conducted including articles that reported 30-days and follow-up mortality, complications, and reintervention rates of patients treated with EVAR using Incraft (Cordis), Zenith LP/Alpha (Cook Medical Inc) and Ovation (Endologix) endografts.
RESULTS
36 papers were evaluated, reporting results of 582 patients treated with Zenith device, 1211 with Incraft and 3449 with Ovation. During follow up, similar survival and freedom from reintervention rates were reported among the various types of endograft both at 1 and 3 years. The incidence of limb stenosis/kinking was significantly higher in patients treated with Zenith LP/Alpha (2.1%, = 0.008), while the Incraft device had a significantly lower proportion of type III endoleaks ( < 0.001).
CONCLUSIONS
Long-term survival and freedom from reintervention rates were comparable among the three LPEs. The Cook Zenith device had the highest rates of limb stenosis/kinking, while the Incraft device had the lowest occurrence of type III endoleak.

Meta-Analysis
BACKGROUND/OBJECTIVE
Effective hemostasis has the potential to reduce inflammation and pain, leading to potential benefits in the early rehabilitation of patients who undergo elbow arthrolysis. In the present study, we aim to assesse the effects of tranexamic acid (TXA) on elbow arthrolysis postoperative blood loss, patients' pain perception according to the visual analog scale (VAS), elbow range of motion (ROM), and complications.
METHODS
We systematically searched PubMed, Web of Science, SCOPUS, and Cochrane Library. We included controlled trials, either randomized (RCT) or non-randomized studies of intervention (NRSI) comparing the effects of intravenous tranexamic acid (TXA) treatment with placebo/no treatment on postoperative blood loss, pain VAS score, elbow ROM, and complications, in patients who underwent open or closed elbow arthrolysis surgery.
RESULTS
One RCT, and three NRSIs met eligibility criteria. The meta-analysis determined that tranexamic acid application reduced drain output 34 mm on average (WMD: -34.00; 95% CI: -49.45, -18.55). There was a discrepancy among included articles in terms of intra-operative blood loss; although the study with the largest sample size (291 and 296 patients in the case and control groups, respectively) reported reduced intra-operative blood loss in patients who received TXA. The pooled estimation for the pain VAS score on the first day post-operatively indicates a reduction in pain among patients in the TXA group (WMD: -0.82; 95% CI: -1.36, -0.28). Results for ROM, and complications' rate such as hematoma and ulnar nerve palsy were not different between the two groups.
CONCLUSION
TXA may be beneficial to reduce elbow arthrolysis bleeding volume. However, it dose not seem to affect final elbow ROM and patients' pain score. Further high-quality clinical trials are needed to draw a robust conclusion on this topic.

Meta-Analysis
BACKGROUND
Hydrocephalus is a common complication after aneurysmal subarachnoid hemorrhage (aSAH). This study aimed to evaluate novel preoperative and postoperative risk factors for shunt-dependent hydrocephalus (SDHC) after aSAH via a systematic review and meta-analysis.
METHODS
A systematic search was conducted using PubMed and Embase databases for studies pertaining to aSAH and SDHC. Articles were assessed by meta-analysis if the number of risk factors for SDHC was reported by >4 studies and could be extracted separately for patients who did or did not develop SDHC.
RESULTS
Thirty-seven studies were included, comprising 12,667 patients with aSAH (SDHC 2214 vs. non-SDHC 10,453). In a primary analysis of 15 novel potential risk factors, 8 were identified to be significantly associated with increased prevalence of SDHC after aSAH, including high World Federation of Neurological Surgeons grades (odds ratio [OR], 2.43), hypertension (OR, 1.33), anterior cerebral artery (OR, 1.36), middle cerebral artery (OR, 0.65), and vertebrobasilar artery (2.21) involvement, decompressive craniectomy (OR, 3.27), delayed cerebral ischemia (OR, 1.65), and intracerebral hematoma (OR, 3.91).
CONCLUSIONS
Several new factors associated with increased odds of developing SDHC after aSAH were found to be significant. By providing evidence-based risk factors for shunt dependency, we describe an identifiable list of preoperative and postoperative prognosticators that may influence how surgeons recognize, treat, and manage patients with aSAH at high risk for developing SDHC.

Meta-Analysis Review
Seamguard Buttressing of the Staple Line During Laparoscopic Sleeve Gastrectomy Appears to Decrease the Incidence of Postoperative Bleeding, Leaks, and Reoperations. A Systematic Review and Meta-Analysis of Non-Randomized Comparative Studies.
Leaks and bleeding are major acute postoperative complications following laparoscopic sleeve gastrectomy (LSG). Various staple line reinforcement (SLR) methods have been invented such as oversewing/suturing (OS/S), omentopexy/gastropexy (OP/GP), gluing, and buttressing. However, many surgeons do not use any type of reinforcement. On the other hand, surgeons who use a reinforcement method are often confused of what kind of reinforcement they should use. No robust and high-quality data supports the use of one reinforcement over the other or even supports the use of reinforcement over no-reinforcement. Therefore, SLR is a controversial topic that is worth our focus. The aim of this study is to compare the outcomes of LSG with versus without Seamguard buttressing of the staple line during LSG.

Frontiers in Neurology 2024This study aimed to explore the prevalence and risk factors of early postoperative seizures in patients with glioma through meta-analysis.
OBJECTIVE
This study aimed to explore the prevalence and risk factors of early postoperative seizures in patients with glioma through meta-analysis.
METHODS
Case-control studies and cohort studies on the prevalence and risk factors of early postoperative seizures in glioma patients were retrieved from various databases including CNKI, Wanfang, VIP, PubMed, Embase, Cochrane Library, and Web of Science, and the retrieval deadline for the data was 1 April 2023. Stata15.0 was used to analyze the data.
RESULTS
This review included 11 studies consisting of 488 patients with early postoperative seizures and 2,051 patients without early postoperative seizures. The research findings suggest that the prevalence of glioma is complicated by seizures (ES = 19%, 95% confidence interval [CI] [14%-25%]). The results also indicated a history of seizures (RR = 1.94, 95% CI [1.76, 2.14], = 0.001), preoperative dyskinesia (RR = 3.13, 95% CI [1.20, 8.15], = 0.02), frontal lobe tumor (RR = 1.45, 95% CI [1.16, 1.83], = 0.001), pathological grade ≤2 (RR = 1.74, 95% CI [1.13, 2.67], = 0.012), tumor≥ 3 cm (RR = 1.70, 95% CI [1.18, 2.45], = 0.005), tumor resection (RR = 1.60, 95% CI [1.36, 1.88], = 0.001), tumor edema ≥ 2 cm (RR = 1.77, 95% CI [1.40, 2.25], = 0.001), and glioma cavity hemorrhage (RR=3.15, 95% CI [1.85, 5.37], = 0.001). The multivariate analysis results showed that a history of seizures, dyskinesia, tumor ≥3 cm, peritumoral edema ≥2 cm, and glioma cavity hemorrhage were indicated as risk factors for glioma complicated with early postoperative seizures.
SIGNIFICANCE
Based on the existing evidence, seizure history, dyskinesia, frontal lobe tumor, pathological grade ≤2, tumor ≥3 cm, partial tumor resection, edema around tumor ≥2 cm, and glioma cavity hemorrhage are indicated as risk factors for glioma complicated with early postoperative seizures.

Meta-Analysis Review
BACKGROUND
The management of concomitant valvular lesions in patients undergoing left ventricular assist device (LVAD) implantation remains a topic of debate. This systematic review and meta-analysis aimed to evaluate the existing evidence on postoperative outcomes following LVAD implantation, with and without concomitant MV surgery.
METHODS
A systematic database search was conducted as per PRISMA guidelines, of original articles comparing LVAD alone to LVAD plus concomitant MV surgery up to February 2023. The primary outcomes assessed were overall mortality and early mortality, while secondary outcomes included stroke, need for right ventricular assist device (RVAD) implantation, postoperative mitral valve regurgitation, major bleeding, and renal dysfunction.
RESULTS
The meta-analysis included 10 studies comprising 32 184 patients. It revealed that concomitant MV surgery during LVAD implantation did not significantly affect overall mortality (OR:0.83; 95% CI: 0.53 to 1.29; p = 0.40), early mortality (OR:1.17; 95% CI: 0.63 to 2.17; p = 0.63), stroke, need for RVAD implantation, postoperative mitral valve regurgitation, major bleeding, or renal dysfunction. These findings suggest that concomitant MV surgery appears not to confer additional benefits in terms of these clinical outcomes.
CONCLUSION
Based on the available evidence, concomitant MV surgery during LVAD implantation does not appear to have a significant impact on postoperative outcomes. However, decision-making regarding MV surgery should be individualized, considering patient-specific factors and characteristics. Further research with prospective studies focusing on specific patient populations and newer LVAD devices is warranted to provide more robust evidence and guide clinical practice in the management of valvular lesions in LVAD recipients.

Review
OBJECTIVE
The primary objectives of this scoping review were to assess the rate of and risk factors for type Ib endoleak and to evaluate the extent of the evidence base that links type Ib endoleak to short and long term outcomes in patients undergoing endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA).
METHODS
Potentially eligible studies were searched in the Cochrane Central Register of Controlled Trials, MEDLINE, Web of Science Core Collection, SciELO Citation Index, Russian Science Citation Index, and KCI-Korean Journal Database. A scoping review was performed according to PRISMA extension for Scoping Reviews.
RESULTS
A total of 27 articles (four prospective registries and 23 retrospective cohort studies) dealing with type Ib endoleak were included in the final analysis. The number of patients reported on was 7 197, with follow up ranging between 12 months and 93 months. The reported frequency of type Ib endoleak in patients treated with EVAR ranged from 0% to 8%, Patient and or procedure related factors associated with risk of type Ib endoleak were (1) common iliac artery (CIA) diameter ˃ 18 mm requiring use of flared stent graft limbs (FLs) ˃ 20 mm, (2) length of CIA landing zone ˂ 20 mm, (3) marked iliac tortuosity, and (4) large initial AAA diameter. Depending on the study, 50 - 100% of type Ib endoleaks were corrected by endovascular means, with a reported immediate technical success of 100% in the studies providing this information.
CONCLUSION
Type Ib endoleak after EVAR has been reported to occur in 0 - 8% of cases. Several anatomical features, including CIA diameter ˃ 18 mm or requiring the use of FLs ˃ 20 mm, length of CIA landing zone ˂ 20 mm, marked iliac tortuosity, and large initial AAA diameter, could increase the risk of type Ib endoleak and may require alternative therapeutic options and or more stringent follow up. Therefore, this updated scoping review provides a comprehensive summary of the frequency, risk factors, prognosis, and treatment of type Ib endoleaks, and has identified knowledge gaps in the literature to guide further studies.

Review
A complete understanding of the rare neurosurgical phenomenon of co-occurring meningioma and intracranial aneurysm is important to improve the quality of life and decrease future complications in these patients. In this review, we searched the literature for cases of this rare phenomenon to highlight the most important historical, investigation, and treatment-related factors to improve the accuracy of intraoperative procedural decisions. We searched the PubMed database for case reports on this neurological rare phenomenon to create organized data for our review. Then, we extracted information from these cases and organized it in a table. We identified 19 cases in the literature. In the published studies, there was a predominance of the female sex (73.68%). The mean age of the patients was 54.11 years, with the cases relatively evenly distributed among patients in their 30s, 40s, 50s, 60s, and 70s. Posterior communicating artery aneurysm was the most common among the 19 cases. For meningioma, the frontal lobe and clinoid were the two most affected locations, and the meningothelial histopathology was the most common. Complete tumor resection and aneurysmal clipping were done for the majority of the cases (57.8%) unless there was a complication that deferred simultaneous intervention. Fortunately, most patients (78.95%) recovered completely after surgery. The coexistence of meningioma and intracranial aneurysm has a very high cure rate, postoperative symptom resolution, and a very low recurrence rate. For most cases, neuroimaging investigations are recommended for simultaneous management. This imaging can also highlight other potentially suspicious findings.

OBJECTIVE
Delayed cerebral ischemia (DCI) associated with vasospasm is well described in the setting of aneurysmal subarachnoid hemorrhage (SAH). In addition, DCI is very infrequently encountered in patients who have undergone resection of a brain tumor with unclear pathophysiology. The occurrence of DCI in the pediatric population is exceedingly rare, and outcomes in this population have, to the authors' knowledge, never been systematically reviewed. Therefore, the authors present what is to their knowledge the largest series of pediatric patients with this complication and systematically reviewed the literature for individual participant data.
METHODS
The authors conducted a retrospective review of 172 sellar and suprasellar tumors in pediatric patients who underwent surgery at the Montreal Children's Hospital between 1999 and 2017 to identify cases of vasospasm occurring after tumor resection. Descriptive statistics, including patient characteristics, intraoperative and postoperative findings, and outcome status, were collected. A systematic review was also conducted using three databases (PubMed, Web of Science, Embase) to identify reported cases available in the literature of vasospasm after tumor resection in children and collect individual participant data on these patients for further analysis.
RESULTS
Six patients treated at Montreal Children's Hospital were identified, with an average age of 9.5 years (range 6-15 years). The prevalence of vasospasm after tumor resection was 3.5% (6/172). Vasospasm in all 6 patients occurred after craniotomy was performed to treat a suprasellar tumor. The average interval from surgery to symptoms was 3.25 days (range 12 hours-10 days). The most common tumor etiology was craniopharyngioma, seen in 4 cases. Extensive tumor encasement of blood vessels requiring significant operative manipulation was described in all 6 patients. A rapid decrease in serum sodium (exceeding 12 mEq/L/24 hrs or below 135 mEq/L) was seen in 4 patients. On final follow-up, 3 patients were left with significant disability, and all patients had persistent deficits. A systematic review of the literature revealed a total of 10 other patients whose characteristics and treatment were compared with those of the 6 patients treated at Montreal Children's Hospital.
CONCLUSIONS
Vasospasm after tumor resection in children and youth is likely a rare entity, with a prevalence of 3.5% in this case series. Suprasellar tumor location (particularly craniopharyngioma tumor etiology), significant encasement of blood vessels by the tumor, and postoperative hyponatremia may be predictive factors. Outcome is poor, with most patients having significant persistent neurological deficits.

Annals of Vascular Surgery Aug 2023We investigated the safety and feasibility of single branched endografts in the treatment of zone II thoracic endovascular aortic repair (TEVAR). (Meta-Analysis)
Meta-Analysis Review
BACKGROUND
We investigated the safety and feasibility of single branched endografts in the treatment of zone II thoracic endovascular aortic repair (TEVAR).
METHODS
We performed a systematic research on Medline, Scopus and EMBASE for articles published up to February 2023. Primary end points included technical success, 30-day mortality, stroke and spinal cord injury (SCI) as well as unassisted left subclavian artery (LSA) branch patency by the end of follow-up. Secondary end points included early 30-day and persistent endoleaks, new onset dissection and reintervention by the end of follow-up.
RESULTS
Fourteen studies, three prospective case series and 11 retrospective case series comprised of 727 patients were finally included. The pooled technical success and 30-day mortality rates were 94.86 % (95% confidence interval (CI): 90.95-97.86) and 0.14% (95% CI: 0.00-0.87). The 30-day stroke and SCI rates were 0.45% (95% CI: 0.00-1.39) and 0.08% (95% CI: 0.00-0.99), respectively, while the unassisted LSA branch patency estimate was 99.12% (95% CI: 97.97-99.86). The early 30-day and persistent endoleak rates were 5.19% (95% CI: 2.45-8.65) and 2.57% (95% CI: 0.36-6.02), whereas new onset dissections and reinterventions estimates were 0.94% (95% CI: 0.17-2.11) and 2.40% (95% CI: 0.41-5.42).
CONCLUSIONS
While we have displayed the safety and feasibility of single branched endografts in the treatment of zone II thoracic aortic lesions, physicians should be aware of the persistency displayed by early type I endoleaks eventually requiring reintervention. The variations in device and lesion characteristics accompanied by the short-term follow-up presented in our review do not allow for definite conclusions to be drawn, necessitating further research through high-quality randomized controlled trials.
