A 45-year old male with no prior cardiac history, presented with cardiogenic shock in the setting of an anterolateral ST elevation myocardial infarction. We first placed a 2.5 Impella for hemodynamic support, and proceeded with emergent percutaneous coronary intervention to the proximal LAD. Several hours following percutaneous coronary intervention (PCI), the patient became acutely hypotensive and an echocardiogram revealed the Impella catheter was kinked within the left ventricle. The patient was taken back to the cath lab for Impella adjustment; however, damage to the distal catheter required the Impella be exchanged...

BACKGROUND: Vascular occlusion is a rare, but serious complication after kidney transplantation often resulting in graft loss. We therefore aimed to develop an experimental porcine model for stepwise reduction of the renal venous blood flow and to compare an implantable Doppler probe and microdialysis for fast detection of vascular occlusion. METHODS: In 20 pigs, implantable Doppler probes were placed on the renal artery and vein and a microdialysis catheter was placed in the renal cortex...

A wide spectrum of molecules is retained in end-stage kidney disease, normally defined as uremic toxins. These solutes have different molecular weights and radii. Current dialysis membranes and techniques only remove solutes in the range of 50-15,000 Da, with limited or no capability to remove solutes in the middle to high molecular weight range (up to 50,000 Da). Improved removal has been obtained with high cut-off (HCO) membranes, with albumin loss representing a limitation to their practical application...

INTRODUCTION: Negative Pressure Wound Therapy (NPWT) has proven to be a powerful tool in facilitating healing of difficult wounds of a variety of etiologies. The pediatric experience with NPWT has been limited due to concerns about vascular compression and pain associated with treatment. METHOD: A retrospective review was performed to evaluate the therapeutic effect of NPWT on children with difficult wounds due to burns or soft-tissue trauma. NPWT was instituted in the operating room under general anesthesia using a commercially available system...

Catheterization of laboratory mice is commonly performed in biomedical research to infuse substances and for blood sampling. One approach is to catheterize the right common carotid artery and advance the catheter until the tip is positioned in the aorta or the proximal brachiocephalic trunk. Owing to the small body size of the mouse, a catheter tends to occupy a great part of even the larger vessel lumens, and this may increase vascular resistance with potential pathophysiological impacts on the heart. The present study compared cardiac function of catheterized mice, with catheter tip placement in the brachiocephalic trunk, with sham-operated mice and non-operated control mice...

Extracorporeal membrane oxygenation (ECMO) is a life support technique used in patients with respiratory and/or cardiac failure. The ECMO circuit consists of vascular cannulae, a pump and an artificial lung. Infections are among the most common complications associated with ECMO and have a significant impact on the mortality rate. Here we present a narrative literature review regarding the epidemiology, risk factors, pathogenesis and prevention of infectious complications during ECMO support. The prevalence of hospital-acquired infections during ECMO is 10-12% and their occurrence is likely to be more frequent compared with other critically ill patients...

A medical adhesive can be defined as a product used to secure a device (ie, tape, dressing, catheter, electrode, and ostomy pouch) to the skin. Skin injury related to medical adhesive usage occurs across all care settings with medical adhesive-related skin injuries (MARSIs) playing a significant role with patient safety. The purpose of this descriptive prospective study was to assess all adult patients with wounds seen in the vascular clinic for MARSI by the CWOCN NP over a 3-month time period. One hundred twenty patients comprising a total of 207 visits were seen by the CWOCN NP over the 3-month time frame...

BACKGROUND AND OBJECTIVES: People receiving hemodialysis to treat kidney failure need a vascular access (a fistula, a graft, or a central venous catheter) to connect to the blood purification machine. Higher rates of access complications are considered the mechanism responsible for the excess mortality observed among catheter or graft users versus fistula users. We tested this hypothesis using mediation analysis. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We studied incident patients who started hemodialysis therapy from North America, Europe, and Australasia (the Dialysis Outcomes and Practice Patterns Study; 1996-2011)...

Presented is a case of a hepatic calcified mass complicating umbilical vein catheterization in a neonate and diagnosed by wedge biopsy. Wedge biopsy of the hepatic mass, situated in proximity to the falciform ligament, revealed expansion of portal tracts by fibrosis and calcification. Some aggregates of calcified material appeared in ectatic vascular spaces. The biopsy findings accounted for the radiographic appearance of the mass and the constellation of features were deemed indicative of calcification secondary to umbilical vein catheterization...

BACKGROUND: It is technically challenging to design compact yet sensitive miniature catheter radio frequency (RF) coils for endovascular interventional MR imaging. METHODS: In this work, a new design method for catheter RF coils is proposed based on the coaxial transmission line resonator (TLR) technique. Due to its distributed circuit, the TLR catheter coil does not need any lumped capacitors to support its resonance, which simplifies the practical design and construction and provides a straightforward technique for designing miniature catheter-mounted imaging coils that are appropriate for interventional neurovascular procedures...

BACKGROUND/AIMS: All hemodialysis (HD) patients are generally recommended to create a fistula first; but to create a mature arteriovenous fistula (AVF) can be challenging in elderly individuals. It is unclear if elderly incident HD patients derive a survival benefit from an AVF over an arteriovenous graft (AVG) or a tunneled central venous catheter (TDC). METHODS: We examined the association of vascular access type (AVF, AVG, and TDC with and without a maturing AVF/AVG at dialysis transition) at HD initiation with all-cause, cardiovascular (CV), and infection-related mortality in 46,786 US veterans using Cox models with adjustment for confounders...

REVIEW
Richard R Heuser
Even though cardiovascular disease (CVD) is still the leading cause of death in the United States, stroke is the second leading of global cause of death behind CVD . In the 21st Century, less than 40% of overall stroke patients are discharged to home and almost 25% of Medicare beneficiaries do not survive 90days. In spite of the fact that tissue plasminogen activator (TPA) has been approved for stroke care for 20years, only .75% of annual strokes are actually treated with intravenous (IV) TPA. Similar to how interventional cardiologists evolved from IV to catheter mechanical treatment for acute myocardial infarctions (AMI) over 30years ago, over the last few years, neurointerventionists now perform endovascular stroke therapy in many of these patients using stent retrievers...
