Loeys-Dietz syndrome (LDS) is a rare connective tissue disorder (CTD) caused by mutations in the gene encoding transforming growth factor-β receptors Ⅰ and Ⅱ. Patients with LDS manifest spontaneous aneurysms and dissections of the aorta and peripheral artery. We report a successful treatment with a hybrid endovascular repair for a rapidly expanding thoracoabdominal aneurysm in a 41-year-old woman affected by LDS. To overcome the difficulties of anatomical and surgical repair, we applied an original strategy using surgeon-modified fenestrated endografts...

Liver sinusoidal endothelial cells present unique morphology characterized by the presence of transmembrane pores called fenestrations. The size and number of fenestrations in live cells change dynamically in response to variety of chemical and physical factors. Although scanning electron microscopy is a well-established method for investigation of fixed liver sinusoidal endothelial cells morphology, atomic force microscopy is the interesting alternative providing detailed 3D topographical information. Moreover, simple sample preparation, only by wet-fixation, minimizing sample preparation artifacts enable high-resolution atomic force microscopy-based measurements...

Endovascular redo aortic operations are a challenging undertaking. Techniques for treatment date almost as far back as the original open repair itself. Risk factors for failure following aortic repair include larger AAA necks, severe neck angulation, as well as clinical variables such as age, family history, obesity and chronic obstructive pulmonary disease. The armamentarium of endovascular treatments is vast and increasing. Aside from provisional embolization of endoleaks or deferment to open repair conversion, attention should be directed toward obtaining adequate proximal and distal sealing...

BACKGROUND: Cavum Septum Pellucidum (CSP), which are often found incidentally in a small number of populations, rarely, become symptomatic if enlarged significantly. Wilson's disease (WD) is an uncommon, autosomal recessive, inborn defect in copper metabolism characterized by abnormal accumulation of copper in various tissues, particularly in the liver and the brain. Seizure disorder, though rare both in CSP and WD, may happen in a very small percentage of patients in either of the two...

The ventriculus terminalis (VT) is a small ependyma-lined cavity within the conus medullaris that is in direct continuity with the central canal of the spinal cord. Cystic dilatation of the ventriculus terminalis on its own is an extremely rare pathological event in adults whose pathogenesis is uncertain. VT has been described in children as a normal developmental phenomenon. These lesions are often diagnosed incidentally during imaging and are in most cases asymptomatic, especially in children. Symptomatic dilatation of VT in adults is a rare condition with 61cases being reported to date...

BACKGROUND: Cavum septum pellucidum (CSP) and cavum vergae are actually fluid-filled, generally communicating midline cavities located between the third ventricle and corpus callosum. There have been various reports of their association with many behavioral and psychiatric disorders. Infrequently, they have been associated with an obstructive hydrocephalus-like picture. Although the structure and management of CSP has long been known, it has been an enigma as far as functional significance and management indications are concerned...

Cardiopulmonary exercise testing (CPET) aids in clinical assessment of patients with Fontan circulation. Effects of persistent fenestration on CPET variables have not been clearly defined. Associations between fenestration and CPET variables at anaerobic threshold (AT) and peak exercise were explored in the Pediatric Heart Network Fontan Cross-Sectional Study cohort. Fenestration patency was associated with a greater decrease in oxygen saturation from rest to peak exercise (fenestration -4.9 ± 3.8 v. nonfenestration -3 ± 3...

An 18-year-old patient developed multiple infarcts, nine days after endoscopic fenestration of a large arachnoid cyst. We consider vasospasm to be the most likely cause, presumably triggered by a chemical meningitis. Although mostly seen after subarachnoid haemorrhage, vasospasm can also occur after traumatic brain injury, brain surgery or meningitis.

BACKGROUND: Multiple surgical techniques are advised to safely perform cholecystectomy in difficult cases, such as conversion to open surgery or subtotal cholecystectomy (STC). A reconstituting and a fenestrating STC are techniques for STC. The aim of this study was to investigate short and long-term morbidity and quality of life associated with STC and to compare the outcomes after fenestrating and reconstituting STC. STUDY DESIGN: Patients who underwent STC were identified...

OBJECTIVE The endoscopic third ventriculostomy (ETV) is an established and effective treatment for obstructive hydrocephalus. In its most common application, surgeons plan their entry point and the endoscope trajectory for the procedure based on anatomical landmarks, then control the endoscope freehand. Recent studies report an incidence of neural injuries as high as 16.6% of all ETVs performed in North America. The authors have introduced the ROSA system to their ETV procedure to stereotactically optimize endoscope trajectories, to reduce risk of traction on neural structures by the endoscope, and to provide a stable mechanical holder of the endoscope...

PURPOSE: To evaluate outcomes of physician-modified thoracic stent-grafts for the treatment of aortic arch aneurysms. METHODS: A retrospective dual-center analysis was performed involving 36 patients (mean age 74.7±9 years, range 58-91; 27 men) with an aortic arch lesion who were treated between November 2013 and June 2016 using physician-modified thoracic stent-grafts. Half of the patients had a degenerative aneurysm; the remainder had type B dissection (n=9), traumatic transection (n=3), type Ia endoleak after previous endografting (n=5), or aortoesophageal fistula (n=1)...

BACKGROUND: Gangrenous cholecystitis is associated with a higher conversion rate of conversion from laparoscopic to open than acute non-gangrenous cholecystitis. New strategies and techniques are needed to decrease conversion rates and improve outcomes. METHODS: In this article, we provide a richly detailed, illustrated description of a modified fundus-first technique that we have developed over the last 15 years and now use routinely with rare conversions. We also compared outcomes of laparoscopic (LC) and open (OC) approaches for pathologically confirmed gangrenous cholecystitis in 146 patients during 1995-2005, the first 10 years during which these two approaches were performed contemporaneously at our institution on comparable patients...

Patients with wide patent ductus arteriosus and significant pulmonary hypertension not treated in time constitute a significant problem for cardiologists. For these patients, tests that could aid in decision-making for further planning include reversibility and balloon occlusion tests performed in the catheterization laboratory. Devices developed for the closure of ductus as well as different devices with off-label use may be employed in patients scheduled for transcatheter occlusion. When result of reversibility test is borderline positive, the use of fenestrated device may be applicable for selected patients...

Fenestrated vertebrobasilar junction aneurysms are rare vascular lesions. Microsurgical intervention is extremely difficult due to the complex anatomy in the vicinity of these aneurysms. Endovascular neurosurgery appears to be safe and should be considered as the first modality of treatment. This case study details the treatment of an unruptured fusiform fenestrated vertebrobasilar junction aneurysm with endovascular occlusion with stent-assisted coiling. The optimal angiographic exposure and selective microcatheterization of the aneurysm were challenging due to the patient's body habitus, and the aneurysm was large with one dominant fenestrated limb...

Desmoplastic ameloblastoma (DA) is one of the 6 histopathological subtypes of ameloblastoma. Hybrid lesions in which histopathologically conventional ameloblastoma coexists with areas of DA are rare. A 40-year-old male was referred to our hospital complaining of a swelling in the right premolar region of the mandible. A panoramic radiograph showed an area of radiolucency with a well-defined corticated border, whereas computed tomography revealed a unilocular radiolucent lesion and buccal expansion together with cortical perforation...

We estimated the inpatient resource use for a Fontan patient from birth to adulthood and explored factors that might induce cost differences (2014 US dollar). Inpatient costing records from 4 hospitals with greatest numbers of Fontan patients in Australia and New Zealand were linked with the Fontan registry database. Inpatient records between July 1995 and September 2014 for 420 Fontan patients were linked, and the most frequent primary diagnoses were hypoplastic left heart syndrome (20.7%), tricuspid atresia (19...
