REVIEW
Hua Gao, Chunhui Liu, Yazhuo Zhang
The endoscope has traditionally been used in neurosurgery to access a lesion within a natural body cavity. The challenge has been to access and resect deep-seated intraparenchymal lesions using a minimally invasive endoscopic technique. Endoscopic endonasal trans-sphenoidal surgery has gained increasing acceptance by otolaryngologists and neurosurgeons. Surgical procedures of the skull base include exposure, resection, and base reconstruction. These approaches start at the sphenoid sinus, which provides a reference point to important vascular and neural structures...

REVIEW

Central venous catheter use is common among patients undergoing haemodialysis. Catheter related vascular thrombosis is a frequent complication, which results in catheter dysfunction. This may eliminate the affected vein as a potential route of vascular access and leads to significant morbidity of the limbs involved. Despite increasing prevalence, there is a dearth of evidence-based guidelines for managing such catheter related thrombi, often leading to treatment dilemmas in clinical practice. Minimizing the use of central venous catheters for haemodialysis remains the best approach in preventing such adverse complications...

Totally implanted venous access port (TIVAP) systems provide adequate quality of care and life, especially for oncology patients. Long-term vascular access is very important and easy to perform, but in some clinical situations, if patients have a superior caval system occlusion, femoral insertion may be the only option. We present a case of a 70-year-old colorectal adenocarcinoma patient diagnosed with subclavian vein hypoplasia. Her care team decided intraoperatively to implant a port system by the right femoral access...

OBJECTIVES: To assess the safety and efficacy of arteriotomy closure with the intravascular FemoSeal vascular closure device (VCD; St. Jude Medical) compared to manual compression in patients undergoing diagnostic cardiac catheterization via the common femoral artery. BACKGROUND: There is limited evidence on the performance of individual contemporary VCDs compared to manual compression. METHODS: This is a subanalysis of 3018 patients who underwent transfemoral diagnostic coronary angiography and were randomly assigned to arteriotomy closure with either the intravascular FemoSeal VCD or manual compression within the investigator-initiated, large-scale, randomized, multicenter, open-label ISAR-CLOSURE trial...

BACKGROUND: Despite newer generation valves using smaller sized sheaths, 10-20 percent of patients undergoing transcatheter aortic valve replacement (TAVR) require non-femoral artery access for valve delivery. To avoid a trans-thoracic procedure, we have utilized transcarotid (TC) and transcaval (TCav) approaches in these patients. This study compared the results of a contemporary experience with TF, TC and TCav approaches. METHODS: Between January 2015 and March 2017, 491 patients underwent TAVR at our institution of which 463 were included in this analysis...

Patients with end-stage kidney disease who are considering home hemodialysis (HHD) face the challenge of learning to self-cannulate their arteriovenous access. Current practice discourages the use of tunneled central venous catheters, with recent indications that self-cannulating patients have superior outcomes. Patient-level barriers do not appear to preclude a successful HHD program and should not be viewed as insurmountable by healthcare staff or patients. The healthcare team must address patient fears while instructing the patient to perform self-cannulation safely...

OBJECTIVE Cerebrovascular bypass surgery is a challenging yet important neurosurgical procedure that is performed to restore circulation in the treatment of carotid occlusive diseases, giant/complex aneurysms, and skull base tumors. It requires advanced microsurgical skills and dedicated training in microsurgical techniques. Most available training tools, however, either lack the realism of the actual bypass surgery (e.g., artificial vessel, chicken wing models) or require special facilities and regulations (e...

Despite improvements in pre-clinical drug testing models, predictability of clinical outcomes continues to be inadequate and costly due to poor evidence of drug metabolism. Humanized miniature organs integrating decellularized rodent organs with tissue specific cells are translational models that can provide further physiological understanding and evidence. Here, we evaluated 4-Flow cannulated rat hearts as the fundamental humanized organ model for cardiovascular drug validation. Results show clearance of cellular components in all chambers in 4-Flow hearts with efficient perfusion into both coronary arteries and cardiac veins...

BACKGROUND: Transradial access (TRA) for percutaneous coronary intervention (PCI) is associated with a reduced risk of mortality compared with transfemoral access, access site-related bleeding complications, and shorter length of stay. The budget impact from a healthcare system that has largely transitioned to TRA for PCI has not been previously published. METHODS AND RESULTS: Data from 323 656 patients undergoing PCI between 2010 and 2014 were obtained from the British Cardiovascular Intervention Society database...

PURPOSE: Autogenous arteriovenous fistulas are the preferred access for hemodialysis. Yet when created, fistulas often fail to mature, requiring surgical or radiologic interventions before their use. This pilot study measures the vascular wall elasticity and flow gradient using an open-source ultrasound software program designed to aid in assessing fistula maturation. METHODS: A total of seven end-stage renal disease patients were enrolled for our study after providing informed consent...

Vascular access is of vital importance for patients requiring dialysis therapies. AV fistulas have been endorsed by many professional societies as the access of choice, however, subsequent creation does not go without consequences. As the population ages and patients become more medically complex, access failure has become a major cause of treatment complication. For the elderly, this is especially true and there are multiple decision points that require careful reflection before an AVF is placed. This article reviews access considerations for AVF placement in the elderly population and considers the possibility that the fistula first approach to vascular access should not be an absolute...

BACKGROUND: Antiplatelet therapy (APT) is often used on anecdotal grounds to improve vascular access patency. The aim of this study was to assess the role of APT in hemodialysis (HD) patients undergoing arteriovenous fistula (AVF) or graft (AVG) placement. METHODS: All patients in a large HD vascular qualitative initiative database (2011-2017) were included and divided into no antiplatelet therapy (no-APT) vs. any APT [aspirin (ASA) or P2Y12 inhibitors (PI)]. Multivariate [logistic (MLR) and Cox (MCR) regression] analyses were used as appropriate...

BACKGROUND: Femoral arterial access (FAA) during diagnostic coronary angiography (CAG) and percutaneous coronary interventions (PCI) are associated with several vascular complications (VC). VC rate in our experience a decade ago was 3.02% and higher in women (4.7% in women, and 1.67% in men, p < 0.0006), with an OR of 2.81 (95% CI: 1.51-5.22). METHODS: Patients who underwent CAG and PCI utilizing FAA (n = 2617) were separated into Period 1 (2005 to 2008; 1970 patients; Male 1045; Female 925) and Period 2 (2016-2017; 647 patients; Male 357; Female 290)...

PURPOSE: The most preferable vascular access for patients with end-stage renal failure needing hemodialysis is native arteriovenous fistula (AVF) on account of its access longevity, patient morbidity, hospitalization costs, lower risks of infection and fewer incidence of thrombotic complications. Meanwhile, according to National Kidney Foundation (NKF)̸Dialysis Out-comes Quality Initiative (DOQI) guidelines, AVF is more used than before. However, a significant percentage of AVF fails to support dialysis therapy due to lack of adequate maturity...

Intravenous (IV) resuscitation of burn patients has greatly improved outcomes and become a cornerstone of modern burn care. However, the heavy fluids and vascular access required may not be feasible in austere environments, mass casualty, or delayed transport scenarios. Enteral resuscitation has been proposed for these situations; we sought to examine the effectiveness of this strategy on improving burn-induced kidney injury. Anesthetized Yorkshire swine sustaining 40% TBSA full-thickness contact burns were randomized to three groups (n = 6/group): fluid deprivation, ad libitum water access, or 70 mL/kg/d Oral Rehydration Salt solution (ORS)...
