Skin necrosis overlying an arteriovenous fistula at the cannulation site is a common and potentially life-threatening problem, often associated with underlying aneurysm formation. Arteriovenous fistula-skin necrosis generally requires resection of surrounding skin margins and the underlying aneurysmal vessel wall, allowing repair with healthy tissue of the arteriovenous fistula in addition to closure of soft tissue and skin. In patients with insufficient fistula length, salvage of these arteriovenous fistulas may result in difficult or insurmountable cannulation issues leading to attempts at one-needle cannulation dialysis or, most often, catheter placement...

This study was designed to evaluate the application effect of single balloon catheters and dinoprostone on promoting cervical ripening of pregnant women in late-term pregnancy and their influences on stress and inflammatory responses. A total of 160 pregnant women with indications of labor induction were included and randomly divided into the control (n=80) and observation (n=80) groups. Patients in the control group received labor induction by administration of dinoprostone at the vaginal vault, while those in the observation group received labor induction by domestic single balloon catheters...

OBJECTIVE: Although percutaneous transluminal angioplasty is an effective therapy against vascular access failure in hemodialysis patients, recurrent stenosis imposes enormous burden for hemodialysis patients. A nitinol scoring element-equipped helical balloon catheter (AngioSculpt® ) has been altered the landscape for treating several vascular diseases. It is not, however, fully elucidated whether AngioSculpt for advanced vascular access stenosis, difficult to expand by conventional balloons, successfully provides bailout angioplasty...

BACKGROUND: Noncompressible junctional and truncal hemorrhage remains a significant cause of combat casualty death. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an effective treatment for many junctional and noncompressible hemorrhages. The current hospital standard for time of placement of REBOA is approximately 6 minutes. This study examined the training process and the ability of nonsurgical physicians to apply REBOA therapy in an austere field environment. METHODS: This was a skill acquisition and feasibility study...

BACKGROUND: The management of noncompressible torso hemorrhage remains a significant issue at the point of injury. Resuscitative endovascular balloon occlusion of the aorta (REBOA) has been used in the hospital to control bleeding and bridge patients to definitive surgery. Smaller delivery systems and wirefree devices may be used more easily at the point of injury by nonphysician providers. We investigated whether independent duty military medical technicians (IDMTs) could learn and perform REBOA correctly and rapidly as assessed by simulation...

INTRODUCTION: Benign strictures of the biliary system are challenging and uncommon conditions requiring a multidisciplinary team for appropriate management. PRESENTATION OF CASE: The patient is a 32-year-old male that developed a hilar stricture as sequelae of a gunshot wound. Due to the complex nature of the stricture and scarring at the porta hepatis a combined interventional radiologic and surgical approach was carried out to approach the hilum of the right and left hepatic ducts...

Percutaneous coronary intervention (PCI) of mammary artery bypass grafts through a trans-radial (TR) approach can present unique challenges, including coaxial vessel engagement of the guiding catheter, adequate visualization of the target lesion, sufficient backup support for equipment delivery, and the ability to reach very distal lesions. The GuideLiner catheter, a rapid exchange monorail mother-in-daughter system, facilitates successful interventions in such challenging anatomy. We present a case of a patient undergoing PCI of a right internal mammary artery (RIMA) graft via TR access in whom the graft could not be engaged with any guiding catheter...

Esophageal pressure monitoring provides a minimally invasive method to assess the pleural pressure, which can be used to differentiate the lung and chest wall mechanics. The information of transpulmonary pressure, work of breathing, intrinsic positive end-expiratory pressure and respiratory muscle performance can facilitate the proper setting of mechanical ventilation. Esophageal pressure monitoring is still not routinely used in the clinical setting because of difficulty in esophageal balloon catheter placement and data interpretation due to esophageal pressure monitoring has certain technical requirements, and the measurement results are influenced by many factors such as airbag volume, location, esophageal wall elasticity and mediastinal organ weight...

We report three consecutive patients with limb ischemia, where symptoms appeared several days to weeks prior to presentation. In all cases, initial over-the-wire thrombectomy failed due to adherence of the thrombus to the arterial wall. We adopted a new approach of stretching the whole obstructed segment by a series of ballooning using a percutaneous transluminal angioplasty (PTA) catheter. A subsequent thrombectomy was successful in all three cases. No further intervention, such as stenting or bypass surgery, was required...

PURPOSE: Patients admitted to cardiac intensive care unit need administration of drugs intravenously often in concomitance of therapeutic techniques such as non-invasive ventilation, continuous renal replacement therapy and intra-aortic balloon counterpulsation. Therefore, the insertion of central venous catheters provides a reliable access for delivering medications, laboratory testing and hemodynamic monitoring, but it is associated with the risk of important complications. In our study, we tested the efficacy and safety of peripherally inserted central catheters to manage cardiac intensive care...

Standard intravenous chemotherapy delivery to neoplasms relies on simple diffusion gradients from the intravascular to the interstitial space. Systemic perfusion creates untoward effects on normal tissue limiting both concentration and exposure times. Regional intra-arterial therapy is limited by drug recirculation and vascular isolation repeatability and does not address the interstitial microenvironment. Barriers to delivery relate to chaotic vascular architecture, heterogeneous fluid flux, increased interstitial and variable solid tumor pressure and ischemia...

PURPOSE: A complicated course of the femoral route for neurointervention can prevent approaching the target. Thus, we determined whether transcervical access in the hybrid angiosuite is applicable and beneficial in real practice. METHODS: From January 2014 to March 2017, this approach was used in 17 of 453 (3.75%) cases: 11 cerebral aneurysms (4 ruptured, 7 unruptured), 4 acute occlusions of the large cerebral artery, 1 proximal internal carotid artery (ICA) stenosis, and 1 direct carotid cavernous fistula (CCF)...

PURPOSE: As an alternative to cylindrical applicators, air-inflated balloon applicators have been introduced into high-dose-rate (HDR) vaginal cuff brachytherapy to achieve sufficient dose to the vagina mucosa as well as to spare organs at risk, mainly the rectum and bladder. Commercial treatment planning systems which employ formulae in the AAPM Task Group No. 43 (TG 43) report do not take into account tissue inhomogeneity. Consequently, the low-density air in a balloon applicator induces different doses delivered to the mucosa from planned by these planning systems...

A 70-year-old woman with hepatitis C cirrhosis underwent balloon-occluded retrograde transvenous obliteration for hepatic encephalopathy due to spleno-renal shunt. Because the shunt was thick, long, and winding, we used a coaxial and double interruption system, which enables the effective occlusion of the drainage route, and shape-memory coils, which are more physically stable than conventional metallic coils because they form three-dimensional loops. The patient was successfully treated with the combined usage of these devices, resulting in a normal serum ammonia level...

INTRODUCTION: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a technique to control haemorrhage by placing a retrograde catheter in an artery and inflating a balloon at its tip. This retrospective study aimed to evaluate the proportion of injured people who could potentially have benefited from this technique prior to hospitalisation, including on the scene or during transport. METHODS: A retrospective analysis was conducted of all patients with trauma registered in the Paris Fire Brigade emergency medical system between 1 January and 31 December 2014...
