We describe a case of total arch replacement with frozen elephant trunk for chronic type B aortic dissecting aneurysm, which resulted in inadvertent landing of the frozen elephant trunk into the false lumen. A radiofrequency puncture system-assisted controlled endovascular fenestration of the dissection flap was performed at the upper abdominal aorta and subsequent thoracic endovascular stenting, successfully redirecting the blood flow from the false to the true lumen. Our case illustrated a possible way to seal distal reentry in chronic type B aortic dissection...

The outer blood-retina barrier is established through the coordinated terminal maturation of the retinal pigment epithelium (RPE), fenestrated choroid endothelial cells (ECs) and Bruch's membrane, a highly organized basement membrane that lies between both cell types. Here we study the contribution of choroid ECs to this process by comparing their gene expression profile before (P5) and after (P30) the critical postnatal period when mice acquire mature visual function. Transcriptome analyses show that expression of extracellular matrix-related genes changes dramatically over this period...

BACKGROUND AND IMPORTANCE: Tarlov cysts, also known as perineural cysts, have been described as meningeal dilations of the spinal nerve root sheath between the peri- and endoneurium at the dorsal root ganglion. Most often they are found in the sacrum involving the nerve roots. Normally asymptomatic, they have been reported to present with radiculopathy, paresthesias, and even urinary or bowel dysfunction. Sacral insufficiency has not been a well-documented presentation. CLINICAL PRESENTATION: The patient is a 38-year-old female who started to develop left low back pain and buttock pain that rapidly progressed into severe pain with some radiation down the posterior aspect of her left leg...

PURPOSE: To describe a novel endovascular bailout technique for successful completion of target vessel stenting during branched stent-graft repair of thoracoabdominal aortic aneurysms (TAAA) after encountering difficulties with standard catheterization techniques. TECHNIQUE: Technical difficulties when using fenestrated and branched grafts should be expected, especially in difficult anatomy or when an off-the-shelf device (eg, standard 4-branch device) is used that does not perfectly "match" the anatomy...

Arachnoid cysts are intra-arachnoid sacs filled with cerebrospinal fluid representing a rare occurence in neonates. We report the case of a suprasellar arachnoid cyst diagnosed prenatally at 21 weeks gestation on routine obstetric ultrasound. A cystic lesion was picked up incidentally at routine antenatal scan. The cyst was noted to be increasing in size over a series of radiological scans. The cyst was diagnosed as a suprasellar arachnoid cyst compressing the third ventricle and bilateral lateral ventricles...

BACKGROUND: Ankle impingement is a common cause of chronic ankle pain. We retrospectively studied the effectiveness of ultrasound-guided percutaneous needle fenestration of the pathological soft tissues combined with corticosteroid injection to treat this condition. METHODS: We administered a telephone survey to patients who underwent the procedure. Patients were asked questions on the Foot Function Index and queried about their overall satisfaction with the procedure on a scale of 0 (completely unsatisfied) to 10 (very satisfied)...

Although presacral developmental cysts, including epidermoid cysts, are relatively rare diseases, an intrapelvic mass found for the first time in early pregnancy should be followed-up with the possibility of presacral developmental cysts in mind to be alert to the signs of local infection and malignancy. We treated a pregnant patient with presacral cystic disease. During pregnancy, percutaneous fenestration was performed because the cyst caused severe compression symptoms and complicated bacterial infection...

BACKGROUND: Blunt traumatic aortic injury is the second leading cause of death in trauma patients age 4 to 34. Of the patients that are able to receive treatment, mortality rates as high as 40% have been reported. Endovascular repair options have allowed for more expeditious repairs with reduced iatrogenic trauma; however, when the injury involves the ascending aorta or arch, current endografts lack fenestrations needed for cerebral blood flow. Traditionally, on pump cardiopulmonary bypass with systemic anticoagulation has been used to repair these injuries...

An 81 year-old woman was referred for the treatment of a 79 mm-diameter short neck abdominal aortic aneurysm with highly tortuous iliac arteries. She was considered at high risk for open repair and not suitable for standard endovascular repair given the short length of the proximal neck. Delay for a manufactured custom-made fenestrated stent-graft was too long given the diameter of the aneurysm. A flexible stent-graft was preferred because of severe iliac tortuosity. Endovascular repair was performed using a physician-modified Anaconda stent-graft with one fenestration for the left renal artery...

BACKGROUND: Most of the experience on fenestrated endovascular aneurysm repair (F-EVAR) involves the custom-made Zenith® endograft (Cook). The fenestrated Anaconda® endograft (Vascutek) was introduced with the potential advantages of complete repositioning and lack of stent material on the main aortic body for more versatility. However, few data are available. Our objective was to assess its mid-term results in the treatment of complex aortic aneurysms. METHODS: Consecutive patients treated with the custom-made Fenestrated Anaconda® Endograft in France and the Principality of Monaco, from December 2010 to October 2015, were included...

A1899 is a potent and selective inhibitor of the two-pore domain potassium (K2P) channel TASK-1. It was previously reported that A1899 acts as an open-channel blocker and binds to residues of the P1, P2 regions, the M2, M4 segments and the halothane response element. The recently described crystal structures of K2P channels together with the newly identified side-fenestrations indicate that residues relevant for TASK-1 inhibition are not purely facing the central cavity as initially proposed. Accordingly, the TASK-1 binding site and the mechanism of inhibition might need a re-evaluation...

Myung-Hyun Kim
To review recent advances in endoscopic techniques for treating intraventricular lesions via transcortical passage. Articles in PubMed published since 2000 were searched using the keywords 'endoscopy,' 'endoscopic,' and 'neuroendoscopic.' Of these articles, those describing intraventricular lesions were reviewed. Suprasellar arachnoid cysts (SACs) can be treated with ventriculo-cystostomy (VC) or ventriculo-cysto-cisternostomy (VCC). VCC showed better results compared to VC. Procedure type, fenestration size, stent placement, and aqueductal patency may affect SAC prognosis...

REVIEW
Yun Ho Lee, Young Sub Kwon, Kook Hee Yang
Multiloculated hydrocephalus (MLH) is a condition in which patients have multiple, separate abnormal cerebrospinal fluid collections with no communication between them. Despite technical advancements in pediatric neurosurgery, neurological outcomes are poor in these patients and the approach to this pathology remains problematic especially given individual anatomic complexity and cerebrospinal fluid (CSF) hydrodynamics. A uniform surgical strategy has not yet been developed. Current treatment options for MLH are microsurgical fenestration of separate compartments by open craniotomy or endoscopy, shunt surgery in which multiple catheters are placed in the compartments, and combinations of these modalities...

INTRODUCTION: Medical treatment, cerebrospinal fluid (CSF) shunting, and optic nerve sheath fenestration are standard treatments for increased intracranial pressure (ICP) in patients with idiopathic intracranial hypertension (IIH). Venous sinus stenting provides a novel alternative surgical treatment in cases of venous sinus stenosis with elevated ICP. METHODS: 12 consecutive subjects with papilledema, increased ICP, and radiological signs of dural sinus stenosis underwent cerebral venography and manometry...
