Abstract
Artery fenestration is a congenital vascular malformation, often of the intracranial arteries, that causes an aneurysm. However, there have been no reports of artery fenestration causing renal aneurysm. We present the case of a 58-year-old man who developed renin-dependent hypertension. He was aware of heaviness of the head, and his blood pressure was 196/134 mm Hg on 5 mg of amlodipine. Laboratory tests showed hypokalemia, hyperreninemia, and hyperaldosteronemia. An enhanced 3-dimensional computed tomography scan showed a 19-mm renal aneurysm in a branch of the left renal artery, and renal arteriography showed a fenestration in the aneurysm-forming branch. Coil embolization was performed on the central side of the artery forming the aneurysm and fenestration, after which blood pressure, serum potassium, and plasma renin levels improved. The patient in the present case had renin-dependent hypertension as a result of decreased renal blood flow caused by the renal aneurysm and fenestration, which is considered an extremely rare etiology of hypertension.

Abstract
BACKGROUND The optimal therapeutic strategy for drainage of malignant pericardial effusion is not yet determined. Several techniques are described, with different benefits and disadvantages. The literature suggests that surgical drainage of pericardial effusions has less effusion recurrence; however, randomized controlled trials are not available. Due to the nature of the disease, quality of life should always be considered while making treatment decisions. METHODS A retrospective analysis of all consecutive patients from November 2016 until June 2019 of our institution in the Netherlands was performed. All patients underwent laparoscopic pericardial fenestration after echocardiography and request for operative treatment by the cardiologist. The same operation technique was performed in every case. RESULTS Four out of five of our patients needed pericardial fenestration because of oncological diseases. No hemodynamically instability was noted during this fast technique, achieving direct relief of symptoms. No treatment-related morbidity or mortality, nor the need for re-intervention was encountered. We compared the outcome of our five patients with the existing evidence in the literature. CONCLUSIONS In this article, we highlight the laparoscopic transdiaphragmatic pericardial fenestration as a treatment of preference in a non-acute palliative setting. This laparoscopic approach is safe, and can be a valuable alternative among the other well-known approaches.

Abstract
Background and Importance: Intracranial artery fenestrations are very rare, however, when found, there is a high association with cerebral aneurysms. Clinical Presentation: This report describes a patient with multiple anterior and posterior circulation intracranial artery fenestrations and an anterior communicating artery aneurysm presenting with a thunderclap headache found to have a subarachnoid hemorrhage (SAH). The patient was treated with open surgery via clipping after a diagnostic angiography and did very well. Conclusion: There is an association between cerebral fenestrations and aneurysms, but it has not been studied in a prospective manner. This case is unusual in that the patient had both anterior and posterior circulation fenestrations, which is uncommon. Clinicians should have a high index of suspicion in patients being evaluated for SAH who have a cerebral artery fenestration with no aneurysm found.

Abstract
A radicular cyst (RC) is one of the types of inflammatory cyst of odontogenic origin. It is usually associated with nonvital teeth and is mostly observed in males. It is routinely treated by nonsurgical endodontic therapy; however, if the cystic lesion does not respond to endodontic therapy, then surgical intervention with or without regeneration is the treatment of choice, depending upon the size, location of lesion, the bone integrity of the cystic lesion wall, proximity to vital structures and residual bone defect elicit after enucleation, etc., We hereby present successful interdisciplinary management of rare true lateral RC in the interproximal site with respect to teeth number 21 and 22 as well as associated mucosal fenestration that was occurred postoperatively other than its apparent etiology and diagnosis.

Abstract
PURPOSE To evaluate the response of various stent-grafts after laser fenestration and dilation with noncompliant balloons to determine the optimal therapeutic combination for this treatment technique. MATERIALS AND METHODS Five aortic stent-grafts were evaluated ex vivo: the Bolton RelayPlus, Jotec E-vita Thoracic 3G, Medtronic Valiant, Cook Zenith Alpha, and Vascutek Anaconda. Small holes were created using an excimer laser with the grafts submerged in saline. Five rows of 5 fenestrations were created, 4 holes in each row were dilated once with a 6-, 8-, 10-, or 12-mm-diameter noncompliant balloon to the specified nominal pressure (one hole served as the control). The saline solution from each stent-graft was collected and qualitatively analyzed for debris. The fenestrations were evaluated under light and scanning electron microscopes. The maximum diameter and area for each fenestration were measured. The direction and length of tears were assessed. RESULTS The fenestration was feasible and reproducible in all the stent-grafts. The mean area of fenestration ranged from 7.63±1.63 to 14.75±0.73 mm2 when using balloons of 6- and 8-mm diameter, respectively. The 10- and 12-mm-diameter balloons caused a significant increase in area, variability, and tearing. The Anaconda graft tended to tear in the weft direction, while the other devices tore in the warp direction when using the 10- and 12-mm-diameter balloons. Dilation of the RelayPlus and Anaconda grafts with 6- and 8-mm-diameter balloons provided minimal tearing and precise fenestrations. Melted fiber remnants were observed after filtration of the saline solution for all devices. CONCLUSION Laser fenestration and dilation with noncompliant balloons is a relatively simple and reproducible option for revascularization in urgent, complex aortic endovascular repairs. In our model, large balloons (ie, >10 mm) increased the destruction and tearing of the fabric. The maximum dilation recommended is 6 to 8 mm to avoid significant tears. Development of stent-grafts or novel fabrics designed explicitly for fenestration is needed to reduce potential complications.

Abstract
Aims The present study aimed to evaluate the clinical usefulness of endoscopic treatment of suprasellar arachnoid cysts indenting the third ventricle with obstructive hydrocephalus and discuss the clinical features and outcomes of thirteen children treated at our institution. Method We treated thirteen pediatric cases of suprasellar arachnoid cysts indenting the third ventricle with obstructive hydrocephalus between January 2012 and September 2018. Five female and eight male patients were enrolled in the study. The patients had increased intracranial pressure symptoms due to hydrocephaly. Endoscopic treatment was performed in all cases. Results The patients were followed-up for an average of 36.8 months. The postoperative intracranial pressure findings improved. There was a reduction in the size of the cyst and ventricles and enlargement of the cortical sulci. One patient suffered transient oculomotor nerve deficit. No further surgical interventions, such as shunt placement, were required during the follow-up period. The head circumference of two of the patients with macrocephaly were stable during the follow-up. There were no postoperative recurrences detected. Conclusions Endoscopic cyst fenestration and third ventriculostomy are less invasive, safer, and more effective ways to treat suprasellar arachnoid cysts indenting the third ventricle with obstructive hydrocephalus in children with hydrocephaly.

Abstract
Background: Comprehensive knowledge of the internal jugular vein (IJV) regarding its anatomical variations and the pattern of its course is valuable for preventing unexpected injuries during surgical procedures or central venous access. IJV anatomical anomalies such as fenestration and duplication are rare, mainly represented by case reports, and intraoperative findings. Objective: To present two additional cases of IJV anomalies and highlight its clinical presentation, anatomical characteristics, management, and prevalence through an extensive literature review. Methods and Case Reports: From January 2017 to December 2018, we retrospectively collected data of 221 patients undergoing neck dissection (ND) procedures and identified two patients with IJV anomalies (fenestration and duplication) providing a clinical prevalence of ~0.9%. The IJV fenestration referred to an IJV bifurcation that reunites proximal to the subclavian vein, whereas in the IJV duplication both branches remain separated. In both of our cases, the spinal accessory nerve (SAN) crossed the window between the IJV branches. Conclusion: Anatomical variations are more likely to be identified intraoperatively or incidentally, and due to the risk of SAN and vascular injury, special attention should be taken to identify them preoperatively in order to reduce the risk of iatrogenic injury and unexpected complications.

Abstract
Dehiscence and fenestration are commonly confronted alveolar defects. But the combined mucosal and alveolar fenestration is uncommonly reported in the literature as they less often cause pain, and in majority of the cases, only aesthetic complaint is present. This article highlights the case report of a 28-year-old female patient who presented with aesthetic concern about gingival/mucosal fenestration in her right lower central incisor. She had a history of surgical endodontic treatment in the same tooth. In this case, mucosal fenestration was treated with regenerative therapy using bioactive glass with platelet-rich fibrin and free connective tissue graft. The treatment resulted in excellent aesthetic outcome and satisfactory bone healing.

Abstract
OBJECTIVE With the aim of contributing to the discussion on treatment of patients with arachnoid cysts (AC) and their neuropsychological functioning, we present the case of a patient who has undergone surgery of AC located in the left Sylvian fissure. Case description: The patient had no cognitive deficits and no seizures before the cyst's fenestration. After the procedure, however, occurrences of seizures have been observed. Along with the concomitant epileptic seizures, aphasia and serious memory problems also developed. The initial pharmacological treatment of the seizures brought about unsatisfactory results. The treatment was therefore modified a number of times and ultimately, seizures were brought under control to some extent. Despite the varied efforts at neuropsychological rehabilitation, cognitive impairment was still persistent up to a year after the surgery. Conclusions: 1) While referring patients with AC for surgery, one should always consider both the positive outcomes and the unintended and deleterious consequences. A cyst fenestration could in some cases lead to epilepsy and cause neuropsychological symptoms such as anomic aphasia and cognitive deterioration with memory function impairment. 2) Neurological patients, especially the ones qualified for surgery, should always undergo neuropsychological examination. The lack of data from presurgical neuropsychological examination may impact further treatment of neurosurgical patients.

Abstract
Fenestration of the supraclinoid internal carotid artery (ICA) is extremely rare and may occasionally be associated with saccular aneurysms; nevertheless, the natural history remains unclear. The authors reviewed the cases of fenestration of the supraclinoid ICA and evaluated the clinical characteristics and angioarchitecture with particular focus on the incidence for aneurysm development and rupture. Previously reported 24 cases and 1 new case from our institute were examined for the presence of aneurysms (including size and presence of bleb) leading to subsequent subarachnoid hemorrhage (SAH). Furthermore, 16 cases with sufficient information were classified into one of the three types according to the developmental condition of fenestration and fusion site: Type A (developed fenestration in which the ICA appears to duplicate [two cases]); Type B (hypoplastic fenestration fused to the ICA at the origin of the posterior communicating artery [Pcom] [six cases]); and Type C (hypoplastic fenestration fused to the Pcom itself or appeared to be a duplicated Pcom [eight cases]). In type A, the two cases had an aneurysm (100%), one of which caused SAH (50%). In type B, all six cases had an aneurysm (100%), and one of five led to SAH (20%) (one case lacked information regarding SAH). In type C, five of the eight cases had an aneurysm (62.5%), with no SAH (0%). The result suggested that the extent of development of fenestration and the location of fusion are related to the incidence of aneurysms and risk for rupture.

Abstract
It has been reported that Cavin1 deficiency causes lipodystrophy in both humans and mice by affecting lipid metabolism. The ablation of Cavin1 in rodents also causes a significant deviation from Mendelian ratio at weaning in a background-dependent manner, suggesting the presence of undiscovered functions of Cavin1. In the current study, the results show that Cavin1 deficiency causes neonatal death in C57BL/6J mice by dampening the storage and mobilization of glycogen in the liver, which leads to lethal neonatal hypoglycemia. Further investigation by electron microscopy reveals that Cavin1 deficiency impairs the fenestration in liver sinusoidal endothelial cells (LSECs) and impacts the permeability of endothelial barrier in the liver. Mechanistically, Cavin1 deficiency inhibits the RhoA-Rho-associated protein kinase 2-LIM domain kinase-Cofilin signaling pathway and suppresses the dynamics of the cytoskeleton, and eventually causes the reduction of fenestrae in LSECs. In addition, the defect of fenestration in LSECs caused by Cavin1 deficiency can be rescued by treatment with the F-actin depolymerization reagent latrunculin A. In summary, the current study reveals a novel function of Cavin1 on fenestrae formation in LSECs and liver glycogen metabolism, which provide an explanation for the neonatal death of Cavin1 null mice and a potential mechanism for metabolic disorders in patients with Cavin1 mutation.

Abstract
OBJECTIVES This study was conducted to investigate the combined use of fenestrated atrial septal occluder (F-ASO) and targeted medical therapy (TMT) in patients with secundum atrial septal defect (ASD) and severe pulmonary arterial hypertension (PAH). BACKGROUND Treatment of patients with ASD and severe PAH is still challenging. METHODS After ethical approval was obtained, 56 consecutive patients with ASD with severe PAH were included (7 men, 49 women; median age 50.5 years; mean ASD size 26.9 ± 4.6 mm). After 3 months of TMT, transcatheter closure was performed using F-ASO in patients with ratios of pulmonary to systemic blood flow ≥1.5. TMT was continued post-operatively together with 6 months of dual-antiplatelet therapy. The hemodynamic variables during baseline, TMT alone, and combined treatment with F-ASO were compared. RESULTS After only TMT, systolic pulmonary arterial pressure (-14.5 mm Hg; p < 0.001), pulmonary vascular resistance (-3.9 Wood units; p < 0.001), and exercise capacity (+72.0 m; p < 0.001) improved. Ratio of pulmonary to systemic blood flow increased by 0.9 (p < 0.001), with adverse cardiac remodeling (right ventricular dimension +3.5 mm; p < 0.001). Closure with F-ASO (median size 34.0 mm) led to further decrease in systolic pulmonary artery pressure (-6.0 mm Hg; p < 0.001). Follow-up (median duration 10 months) revealed further improvement in exercise capacity (+60.5 m; p < 0.001), with favorable cardiac remodeling (right ventricular dimension -9.9 mm; p < 0.001). In addition, all fenestrations were stable (p = 0.699), with negligible shunt (median ratio of pulmonary to systemic blood flow 1.1) and no complications. One year later, pulmonary artery pressure was normalized in 8 of 19 patients, and PAH recurred in 5 patients after discontinuation of TMT. CONCLUSIONS In patients with ASD and severe PAH, combination of F-ASO and TMT was a safe and effective procedure. Compared with TMT alone, the combined treatment further improved exercise capacity, with favorable cardiac remodeling.

Abstract
Liver sinusoidal endothelial cells (LSECs) form a highly specialized microvasculature that plays a critical role in liver function and disease. To better understand this role, we developed a strategy to generate LSECs from human pluripotent stem cells (hPSCs) by first optimizing the specification of arterial and venous angioblasts and derivative endothelial populations. Induction of a LSEC-like fate by hypoxia, cyclic AMP (cAMP) agonism, and transforming growth factor β (TGF-β) inhibition revealed that venous endothelial cells responded more rapidly and robustly than the arterial cells to upregulate LSEC markers and functions in vitro. Upon intrahepatic transplantation in neonates, venous angioblasts engrafted the liver and generated mature, fenestrated LSECs with scavenger functions and molecular profiles of primary human LSECs. When transplanted into the liver of adult mice, angioblasts efficiently gave rise to mature LSECs with robust factor VIII (FVIII) production. Humanization of the murine liver with hPSC-derived LSECs provides a tractable system for studying the biology of this key liver cell type.

Abstract
Cerebral artery fenestration is a rare variant of the vascular architecture, but its existence is well documented. The common site of fenestration is the vertebra-basilar artery and it may be found incidentally with subarachnoid hemorrhage. However, fenestration-related cerebral infarction is rare. We analyzed the clinical characteristics, stroke etiology, and image findings of fenestration-related cerebral infarction of the vertebrobasilar artery. We reviewed our hospital records and previously published reports to find cases of fenestration-related cerebral infarction. We excluded those with unknown clinical features or radiological findings. We retrieved 4 cases of fenestration-related infarction from our hospital, in which vascular change, headache, vertigo/dizziness, and dissection in stroke etiology were detected. In eight previously reported cases of fenestration-related infarction, similar vascular changes were noted, but they were mainly diagnosed as embolic stroke of undetermined source. However, based on the criteria for dissection in this study, dissection as the stroke etiology was suspected in the previously reported cases. Many hypotheses have been proposed for the development of dissection, thrombus, and aneurysms in fenestration. Although an embryological and morphological study is needed, clinicians must consider basilar artery fenestration-related infarction as a differential diagnosis and intensive non-invasive image study is recommended.

Abstract
Purpose: To present a simple method to avoid favored passage of a guidewire into the profunda femoris artery (PFA) after antegrade puncture of the common femoral artery. Technique: A 6-F conventional introducer sheath with a radiopaque distal marker is placed on the nurse's table with its side port orientated to the 12 o'clock position. A small (2-2.5 mm) oval fenestration is created on the superior aspect of the sheath about 3 cm from its tip with a size 11 surgical blade. The modified introducer is passed over the angled 0.035-inch guidewire into the PFA and gently retrieved until the tip marker is ~3 cm from the femoral bifurcation. The dilator is removed, and the guidewire is withdrawn to the level of the fenestration, manipulated through it, and advanced further into the superficial femoral artery under fluoroscopic guidance. Conclusion: When repeated passage of the guidewire down the PFA persists despite conventional manipulation of the wire or needle, an on-site modification of the sheath is an easy alternative approach for the catheterization of the superficial femoral artery.

Abstract
A complete excision is the most reliable therapy for bronchogenic cysts (BC) but is often accompanied by technical difficulties due to severe adhesions. An 83-year-old-woman with poorly controlled diabetes noted worsening upper abdominal pain after meals and paroxysmal atrial fibrillation. Magnetic resonance imaging revealed a cystic mass in the subcarinal region, and she underwent a thoracoscopic prone position surgery. The cyst wall was found to have strictly adhered to the adjacent organs, and the lesion was not amenable to a complete excision. We performed a fenestration of the cyst wall with the aspiration of an yellowish mucus content. After opening the cavity wide enough, the remnant luminal epithelium was ablated by electrocautery. Her clinical symptoms disappeared immediately after the surgery without any surgical morbidity. A prone-position thoracoscopic palliative fenestration is a feasible option for a symptomatic subcarinal BC.

Abstract
OCT in a 74-year-old woman highlights how an angiographic coronary fenestration can be acquired through calcific nodule atherosclerosis in the coronary arteries. We demonstrate how tandem anatomic and physiologic assessment can be used to diagnose, functionally evaluate, and effectively treat this rare finding.

Abstract
Background: Prolonged pleural effusion (PPE) contributes to adverse outcomes after total cavopulmonary connection (TCPC) completion. We aimed to identify risk factors for PPE following TCPC surgery. Methods: We studied a retrospective cohort of 525 who undergoing TCPC surgery from 2010 to 2019. We defined PPE as the duration of pleural effusion exceeding 14 days. Logistic regression was applied to identify risk factors for PPE and Cox regression was used to identify risk factors for predicting the duration of pleural effusion. The impacts of PPE on the short-term outcomes were evaluated. Results: The rate of PPE was 27.4% in our study and independent risk factors for PPE included: young age, no fenestration, low postoperative total protein, prolonged mechanical ventilation and chylothorax. These predictors were also achieved in the Cox regression for predicting the duration of pleural effusion. The applicability of the model was acceptable in different subgroups, which derived from the total cohort. Patients with PPE were associated with more renal replacement treatment, longer length of ICU and hospital stay, more hospitalization costs and a higher rate of in-hospital mortality. Conclusions: PPE in our study occurs at a relatively lower rate than that reported in previous studies and patients with PPE was associated with higher rate of in-hospital mortality when compared to patients without PPE. Young age, no fenestration, low postoperative total protein, prolonged mechanical ventilation, and chylothorax were identified as independent risk factors to predict PPE. A preventive strategy that targets the identified risk factors to reduce the incidence of PPE following TCPC surgery could be beneficial for in-hospital outcomes, and the model needs further validation before its application.

Abstract
Symptomatic seminal vesicle cysts (SVCs), especially those of a large size, can be removed by surgical treatments. Currently, open surgeries for SVC are rarely performed due to their extensive surgical trauma, and minimally invasive surgical therapies for treating seminal vesicle cysts are still in the early stages. In addition, relevant studies are mostly confined to case reports. In this study, we retrospectively reviewed 53 patients who had received transperitoneal laparoscopic unroofing or fenestration under seminal vesiculoscopy for SVC in our institution. Both surgeries decreased the cyst volume to a significant extent; however, according to the remnant lesion size after rechecking images, seminal vesiculoscopic fenestration tended to have a higher recurrence than laparoscopic unroofing. Regarding complications, two individuals in the laparoscopic unroofing group experienced ureteral injury and rectal injury, while patients in the fenestration group only had temporary hemospermia, which indicates that fenestration surgery tends to have less severe complications than laparoscopic unroofing. There was no solid evidence confirming semen improvement after these surgical therapies in our study. Future studies with a prospective design, larger sample size, and longer follow-up period are required to verify and further explore our findings.

Abstract
A new approach was used in the percutaneous treatment of two patients with severe recoarctation involving the origin of the left subclavian artery. A tiny handmade fenestration was created in a NuMED-covered Cheatham-platinum stent before its implantation to avoid left subclavian artery occlusion. The stent placement was performed using a two-guidewire technique in which the different stiffness helped a proper positioning of the stent. After the stent deployment, the fenestration was enlarged performing a balloon angioplasty to improve flow in left subclavian artery.

Abstract
OBJECTIVE To evaluate the bony support around the teeth adjacent to the unilateral cleft lip and palate (ULCLP) using cone-beam computed tomography. METHODS AND MATERIALS Cone-beam computed tomographies of 48 cleft-adjacent teeth (28 anterior and 20 posterior to the cleft) and 48 noncleft control teeth were evaluated. The alveolar bone thickness at 3 and 6 mm apical to the cement-enamel junction (CEJ), the distance between the alveolar crest and CEJ (Alv-CEJ), and the presence of fenestration were assessed in buccal, palatal, and proximal surfaces. RESULTS The alveolar bone on the buccal and palatal sides of the teeth anterior to the cleft was significantly thinner than the noncleft teeth (all P < .05). The Alv-CEJ was significantly greater on the buccal and distal surfaces of the teeth anterior to the cleft (P < .001 and P = .010, respectively) and on the palatal and mesial surfaces of the teeth posterior to the cleft (P = .024 and P = .003, respectively) when compared to the noncleft teeth. The frequency of reduced alveolar bone height (>2 mm) was higher than noncleft side for buccal and distal sides of the teeth anterior to the cleft (P = .016 and .006, respectively) and the buccal and mesial sides of the teeth posterior to the cleft (P = .008 and <.001, respectively). The teeth anterior to the cleft had a higher prevalence of fenestration (P = .004). CONCLUSION Reduced alveolar bone height is more common in the cleft side compared to the control side. The teeth anterior to the ULCLP have thinner alveolar bone support and higher frequency of fenestration.
