    Abstract: Carotid endarterectomy (CEA) with patch angioplasty has been favored due to its lower reoccurrence of restenosis compared to primary CEA. There are multiple types of patch angioplasty material available. However, selection of patch material is based on uncertain criteria. The aim of this study is to determine the ideal criteria for selecting the best patch material for CEA. Methods: We conducted a comprehensive literature search for studies that describe the ideal criteria for selecting patch material for CEA. We compiled all of the criteria mentioned into one table and selecting the criteria which were most frequently mentioned with a simple scoring system. Results: A total of 65 studies out of 784 studies were assessed for its full-text eligibility. Thus, we found 23 studies that were eligible for analysis. There are 22 ideal criteria that were mentioned in the analyzed studies. We grouped these criteria into physical characteristics, safety, contribution to hemodynamic, contribution in tissue healing, economic aspect, and ability to prevent postsurgical complication. We proposed 10 ideal criteria for guiding vascular surgeon in selecting the best patch angioplasty material. Conclusion: To this day, no material has been discovered which meets all ten criteria. This study’s proposed ideal criteria serve as the foundation for the creation of the best patch angioplasty material.

    Abstract: Several reports on stem cell administration have emerged proving it to be an ideal therapeutic approach for improving neurological functions in ischemic stroke patients. However, some studies also show disappointing results, with some reporting no statistically significant improvements among several different parameters. Several challenges also arise relating to safety and nonscientific aspects, such as ethics. Methods: We performed a systematic review and meta-analysis to evaluate the effect of stem cell therapy on the clinical outcomes of ischemic stroke patients. A systematic review and meta-analysis were performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. A thorough literature search was conducted on PubMed, Scopus, and Cochrane databases. Articles were selected systematically based on the PRISMA protocol and reviewed completely. A total of 19 publications pertaining to stem cell therapy on the ischemic route were included and reviewed. Efficacy outcomes were measured with the National Institutes of Health Stroke Scale, modified Rankin Scale, or Barthel Index. Results: The results of the meta-analysis indicate that the efficacy outcomes suggest favorable results after stem cell therapy, although not all study results are statistically significant. Stem cell therapy in stroke cases showed a better outcome than standard conservative therapy alone, although our analysis shows that many factors can influence this outcome, and significant effects can only be seen after several months. Conclusion: The results of this study show promising and satisfying efficacy and a relatively low rate of serious adverse events.

    Clear-cell renal cell carcinoma and glioblastoma multiforme coexistence: Double primary malignancy, does it have a causal relationship?

    Abstract: Multiple primary malignancies (MPMs), especially coexistence of renal cell carcinoma (RCC) and glioblastoma multiforme (GBM), are rare. The most likely clinical diagnosis in patient with tumor in another organ is metastatic brain tumor. Although GBM is the most common brain tumor, it is rarely coexistent with other malignancies. Case Description: A 64-year-old female presented with headache and dizziness, along with abdominal pain for 2 weeks before being admitted. The abdominal computed tomography (CT) scan showed a kidney tumor. The patient developed left hemiplegia, and the brain CT scan showed an intracranial tumor. The patient suggested for radical nephrectomy and craniotomy tumor removal. Histopathology of the kidney and brain tumor revealed two different features, which showed RCC and GBM. Immunohistochemistry result confirmed the diagnosis of GBM and IDH1 wild type; coexistent with clear cell RCC. Conclusion: The coexistence of carcinoma and glioma should be regarded as coincidental cases if it did not accomplish the criteria for tumor-to-tumor metastasis or proven to be a genetic syndrome. This case report provides an addition to the literature about double primary malignancy in a single patient. More studies are needed to confirm whether they have causal relationship or merely coincidental findings.

    Abstract: Therapeutic reperfusion with endovascular treatment (EVT) for acute ischemic stroke is typically associated with better long-term functional outcome compared to standard medical care. However, post-procedural brain edema remained present in around half of EVT patients. Malignant brain edema (MBE) is a serious condition that can lead to increased intracranial pressure, rapid neurologic deterioration, and cerebral herniation, neutralizing the favorable efficacy of EVT on functional outcomes. Case Description: A 51-year-old man with a history of atrial fibrillation presented with acute onset of hemiplegia and severe bradyarrhythmia. A head computed tomography-scan demonstrated hyperdense middle cerebral artery (MCA) sign. Intravenous thrombolysis was administered before temporary pacemaker insertion. The digital subtraction angiography confirmed occlusion of the M1 branch of the right MCA with no collaterals in the territory of the occluded vessel. Mechanical thrombectomy (MT) was performed 6 h after onset and successfully achieved modified thrombolysis in cerebral infarction 3 revascularization in 6 h 20 min. The patient later experienced massive brain edema that required emergent decompressive craniectomy. The modified Rankin scale score was 4 in 1- and 3-month’s follow-up. Conclusion: MBE after MT results in unsatisfactory functional outcomes, even if it has successful revascularization. No collateral in the territory of the occluded vessel in the initial angiogram is one of the predictors of MBE after MT.

    Abstract: As the largest and most complex cerebral artery, the middle cerebral artery (MCA) patterns and anomalies are not fully reported. At present, there is confusion about the criteria for the different subtypes. The study of MCA patterns and anomalies is important because variants such as accessories or duplicates represent a high risk of failure during endovascular embolization or navigation during treatment for ischemic stroke. This study conducted a systematic review of studies on the neuroangiography patterns and anomalies of MCA. Methods: We conducted a systematic review of four articles online databases and included English articles from PubMed, the Cochrane Library, Directory of Open Access Journals, and EBSCOhost. Results: The proportion of the MCA branching pattern was 1.9% (range from 0% to 6.3%) for monofurcation, 1.0% (range from 0% to 1.4%) for tetrafurcation, 69.9% (range from 58.1% to 92.7%) for bifurcation, and 27% (ranging from 7.3% to 40.4%) for trifurcation. The proportion of MCA anomalies for accessory is 0.03% (range from 0% to 1%), duplication is 0.17% (range from 0% to 3%), and fenestration is 0.15% (range from 0% to 2%). Conclusion: The proportions of the branching pattern and anomalies of MCA based on the systematic review are described in this study. This study is the first to systematically review the neuroangiography pattern of MCA and neuroangiography variations/anomalies of MCA in the literature.
