OBJECTIVES: The authors sought to study the safety and efficacy of the MANTA Vascular Closure Device (VCD), a novel collagen-based technology dedicated to closure of large-bore arteriotomies. BACKGROUND: Novel transfemoral therapeutic interventions requiring large-bore catheters have become valid minimally invasive options but have inherent access management challenges. To date, no dedicated vascular closure devices exist for large arteriotomies. METHODS: A prospective, single-arm clinical investigation enrolling patients who underwent elective percutaneous interventions with large-bore catheters and planned percutaneous arteriotomy closure in 3 European institutions...

Persistent left superior vena cava is the most common congenital venous anomaly of the thoracic venous system, occurring in 0.3% to 0.5% of individuals in the general population. It may remain asymptomatic throughout life and be incidentally found in healthy individuals undergoing vascular procedures such as venous access device placements and endovascular cardiac interventions. Here we present a case of persistent left superior vena cava incidentally realized during chemoport insertion in a patient with breast cancer...

Mesenchymal stem cells (MSCs) represent a promising alternative source for cartilage tissue engineering. However, MSC culture is labor-intensive, so these cells cannot be applied immediately to regenerate cartilage for clinical purposes. Risks during the ex vivo expansion of MSCs, such as infection and immunogenicity, can be a bottleneck in their use in clinical tissue engineering. As a novel stem cell source, pericytes are generally considered to be the origin of MSCs. Pericytes do not have to undergo time-consuming ex vivo expansion because they are uncultured cells...

Vascular access maintenance is vital for hemodialysis patients. Conventional balloon angioplasty is the gold standard of treatment in endovascular therapy according to published guidelines, accompanied by bare metal stents as a bail-out method. Several devices have been used so far with a view to improve patency outcomes, but only covered stents have been proposed as a valid alternative and only for venous juxta-anastomotic stenosis of arteriovenous grafts. Paclitaxel-coated balloons (PCBs) have been extensively investigated in the last few years in pilot studies with small numbers of patients in dialysis access...

The need to have consistent methods and consistent technique to optimize hemodialysis outcomes is behind the concept of the Optiflow™ device. This device was created to allow for consistency in size of the arterial anastomosis and consistency in angle of the vein to the artery at the anastomosis. Early data suggest that allowing these two technical entities can improve outcomes in regards to flow and maturity in arteriovenous fistula creation. This article is a summary of early data that demonstrate the impact the Optiflow device on brachial cephalic fistulas...

Swing-segment lesions are a fairly common reason for access failure and predispose to repeated interventions. The pathophysiology, hemodynamic circumstances and the primary intervention might all play a role in early recurrence. Mainly, percutaneous transluminal angioplasty (PTA), bare metal stenting and stent graft implantation have been performed to prolong lesion patency and access circuit patency. The available data on endovascular treatment of swing-segment lesions are scarce, heterogeneous and of poor quality...

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is used to mitigate bleeding and sustain central aortic pressure in the setting of shock. The ER-REBOA™ catheter is a new REBOA technology, previously reported only in the setting of civilian trauma and injury care. The use of REBOA in an out-of-hospital setting has not been reported, to our knowledge. METHODS: We present a case series of wartime injured patients cared for by a US Air Force Special Operations Surgical Team at an austere location fewer than 3km (5-10 minutes' transport) from point of injury and 2 hours from the next highest environment of care-a Role 2 equivalent...

Safe vascular access is a prerequisite for intravenous drug admission. Discrimination between intra- and extravascular needle position is essential for procedure safety. Spectral tissue sensing (STS), based on optical spectroscopy, can provide tissue information directly from the needle tip. The primary objective of the trial was to investigate if STS can reliably discriminate intra-vascular (venous) from non-vascular punctures. In 20 healthy volunteers, a needle with an STS stylet was inserted, and measurements were performed for two intended locations: the first was subcutaneous, while the second location was randomly selected as either subcutaneous or intravenous...

OBJECTIVE: Barriers to cervical cancer screening in low-resource settings include lack of accessible, high-quality services, high cost, and the need for multiple visits. To address these challenges, we developed a low-cost, intravaginal, optical cervical imaging device, the point-of-care tampon (POCkeT) colposcope and evaluated whether its performance is comparable with a standard-of-care colposcope. MATERIALS AND METHODS: There were 2 protocols, which included 44 and 18 patients...

Sternal intraosseous devices are widely used in both civilian and military trauma when vascular access is difficult to establish. We discuss a rare complication of intraosseous needle insertion in two patients where the needle tip remained in the sternum after the device had been removed. Neither patient had evidence of any complication of the retained intraosseous needle tip after >6 years of follow-up.

Background During aneurysm surgery, neurosurgeons may need to look at the cerebral angiograms again to better orient themselves to the aneurysm and also the surrounding vascular anatomy. Simplification of the intraoperative imaging review and reduction of the time interval between the view under the microscope and the angiogram review can theoretically improve orientation. Objective To describe the use of a smartphone as a remote touchpad to simplify intraoperative visualization of three-dimensional (3D) cerebral angiograms and reduce the time interval between the view under the microscope and the angiogram review...

Central line-associated bloodstream infections (CLABSIs) are preventable through vigilant and thorough care. When CLABSIs occurred at a facility in Southwest Arizona, the root cause analysis discovered that declotting agents, such as alteplase, were not given routinely when nonhemodialysis (non-HD) central vascular access devices (CVADs) lacked blood return. A PICO question was developed that guided the review of literature and central line care standards of practice: In the adult patients with non-HD central lines, what medications are currently recommended to restore patency? As a result of this project, our facility instituted a new protocol using a reduced dose of alteplase to restore patency to non-HD CVADs...

Success of cell therapy in avascular sites will depend on providing sufficient blood supply to transplanted tissues. A popular strategy of providing blood supply is to embed cells within a functionalized hydrogel implanted within the host to stimulate neovascularization. However, hydrogel systems are not always amenable for removal post-transplantation; thus, it may be advantageous to implant a device that contains cells while also providing access to the circulation so retrieval is possible. Here we investigate one instance of providing access to a vessel network, a thin sheet with through-cut slits, and determine if it can be vascularized from autologous materials...

BACKGROUND: Surgical site infections (SSI) represent a significant public health problem as the most common nosocomial infection and a leading cause of unplanned hospital readmissions among surgical patients. Many develop following hospital discharge and often go unrecognized by patients. Telemedicine offers the opportunity to leverage the mobile technology to remotely monitor wound recovery in the transitional period between hospital discharge and routine clinic follow-up. However, many existing telemedicine platforms are episodic, replacing routine follow-up, rather than equipped for continued monitoring; they include only low-risk patient populations and those who already have access to and comfort with the necessary technology; and transmit no visual information...
