Abstract No. 447 Utilization of intravascular ultrasound for identification of thrombus in thoracic veins during tunneled hemodialysis catheter exchange

To evaluate the use of Intravascular ultrasound to identify the incidence of thrombus associated with tunneled hemodialysis catheters, during exchange of said malfunctioning catheters.

CONCLUSION: The technique described allows elevation of the vein to the level of the dermis without division and re-anastomosis or re-tunneling, through several small incisions maintaining virgin skin and normal contour for easier cannulation. PMID: 31992105 [PubMed - as supplied by publisher]

CONCLUSION: Outflow reconstruction through the elbow bypass by cubital vein transposition is a valuable resource to rescue radiocephalic arteriovenous fistula complicated by outflow obstruction, avoiding the use of an interim central vein catheter. Endovascular treatment is vital to maintain functional patency in the mid- and long term. PMID: 31774035 [PubMed - as supplied by publisher]

ández M, Ortiz A Abstract Patients with chronic kidney disease (CKD) are at an increased risk of premature mortality, mainly from cardiovascular causes. The association between CKD on hemodialysis and accelerated atherosclerosis was described>40 years ago. However, more recently, it has been suggested that the increase in atherosclerosis risk is actually observed in early CKD stages, remaining stable thereafter. In this regard, interventions targeting the pathogenesis of atherosclerosis, such as statins, successful in the general population, have failed to benefit patients with very advanced CKD. This ra...

Authors: Tessitore N, Lipari G, Contro A, Moretti F, Mansueto G, Poli A Abstract INTRODUCTION: Guidelines recommend hemodialysis graft screening to identify and repair significant (>50%) stenosis at high risk of thrombosis, but there is insufficient evidence to prefer one or other screening tool due to the lack of studies comparing all available options. METHODS: Seeking an optimal screening approach, we compared the performance of all currently used tools (duplex ultrasound to detect significant stenosis (StD) and measure access blood flow (QaD), ultrasound dilution access blood flow (QaU), static venous in...

Conclusion: Percutaneous ultrasound-guided thrombolytic injection in native hemodialysis fistulas is a rapid, practical, repeatable treatment method that is received on an outpatient basis with low risk of bleeding, and prevents unnecessary endovascular interventions or surgical operations.

We present a male HD patient with cramps during his session, attributed to acute limb ischemia due to thrombosis of a common femoral artery aneurysm (CFAA). The true CFAAs are extremely rare, but the pseudoaneurysms (or false aneurysms) are less uncommon resulting after femoral catheterization for diagnostic and therapeutic procedures. This aneurysm was eccentric in shape which in conjunction with the patient's history of femoral catheterization strongly suggests us to consider it a pseudoaneurysm. Although the patient was operated with the clinical suspicion of arterial embolism due to atrial fibrillation and the subthera...

Authors: Sato T, Otsuka Y, Kikkawa Y, Iwasaki Y, Fukagawa M Abstract Vascular access failure, such as recurrent stenosis and thrombosis, is a major concern in patients with end-stage kidney disease. Neointimal hyperplasia development at the anastomosis site of outflow vessels is a primal cause for recurrent vascular access failure. We previously shed some lights into a role of vitamin D, which exerts a protective effect against neointimal hyperplasia formation. Virtual histology, derived from intravascular ultrasound technology, provides novel insights into plaque composition analysis in atherosclerotic diseases. H...

AbstractPurpose It has been suggested that advanced glycation end products (AGEs) are involved in atherogenesis, vascular calcification and remodeling, including neointimal hyperplasia, in renal and non-renal patients. Their relevance for arteriovenous fistula (AVF) function has been poorly studied to date, with only one clinical study addressing the issue of thrombosis of vascular access in relation to AGEs in dialysis patients. We aimed to evaluate the relationship between serum pentosidine and AVF morphology and function.MethodsEighty-eighth hemodialysis patients with patent native AVF were included. Ultrasound examin...

CONCLUSION: Leaving patients with vascular access dysfunction to fate (no intervention) or AVF ligation is always simpler and easier. However, it should not be forgotten that paternity for vascular access are limited in these patients. We think that the primary target is to demonstrate AVF by physical examination and surgeon-performed detailed US and to make it again available for hemodialysis by reconstructing dysfunctional AVF using the most appropriate surgical strategy. LIMITATIONS: Retrospective, small sample size. PMID: 30899405 [PubMed]
