Plasmablastic lymphoma presenting as a brachial artery aneurysm associated with haemodialysis arteriovenous access ligation in a renal transplant patient.
CONCLUSION: Brachial artery aneurysms are a rare complication in kidney transplant recipients after ligation of arteriovenous access for haemodialysis. Here, we report a case in which this condition is associated with an even rarer plasmablastic lymphoma. A common aetiology, due to immunosuppressive therapy, is postulated for the two coexisting diseases. PMID: 31244374 [PubMed - as supplied by publisher] (Source: The Journal of Vascular Access)

FemoSeal ® vascular closure device for antegrade common femoral artery access: Safety and technical notes.
CONCLUSION: The low rate (7%) and grading of the adverse events, combined with the high technical success rate (100%), in an unselected group of patients treated in daily routine, suggest high safety and efficacy of FemoSeal vascular closure device in antegrade common femoral artery puncture site hemostasis when using vascular sheaths ranging from 5 to 8 Fr. Therefore, FemoSeal could be considered as a first-line hemostasis strategy in such cases. PMID: 31232151 [PubMed - as supplied by publisher] (Source: The Journal of Vascular Access)

Transposition of external jugular to proximal internal jugular vein for relief of venous thoracic outlet syndrome and maintenance of arteriovenous fistula access for chronic hemodialysis: A new approach.
Authors: DeGiovanni J, Son A, Salehi P Abstract We are reporting a case of venous thoracic outlet syndrome with recurrent subclavian vein thrombosis in the setting of an ipsilateral brachiocephalic arteriovenous fistula for hemodialysis that was malfunctioning due to the central vein obstruction. The patient also had a concomitant external jugular vein origin stenosis. Given her body habitus and aversion to recovery after traditional first rib resection, we elected for an alternative treatment with an external jugular vein to internal jugular vein transposition with balloon angioplasty of the stenosed external jugu...

Prone positioning for peripherally inserted central catheter on a patient with anal cancer.
Authors: Longo F, Costa F, Piliego C, Agrò FE Abstract Peripherally inserted central catheters are usually inserted in supine patients. What should we do when facing a patient who cannot tolerate this position? In this article, we are describing a particularly difficult patient: not only supine decubitus was intolerable to her but lying on the side was unbearable, too. That is why, to manage a patient who required a central access but could not tolerate the usual position for placing it, we tried to do that in prone position.

Advances in technology have allowed the addition of this universally available, portable, non-invasive tool to the nephrologist's armamentarium, which provides information on both morphology and physiology without the need for contrast or radiation. Ultrasound may be used across the spectrum of dialysis access, including central venous catheter placements, vascular mapping, regional anesthesia, creation, maintenance and assessment of hemodialysis access as well as assessment of the ab...

CONCLUSIONS: Anatomical variations in depth and diameter as well as the collapsibility due to intrathoracic pressures changes represent common challenges that face clinicians during central venous catheterization of the axillary vein. A noteworthy increase in vessel size as patients transition from spontaneous to mechanical ventilation may theoretically improve first-pass cannulation success with practitioners skilled in both ultrasound and procedure. As a result, placing a centrally inserted central catheter after the induction of anesthesia may be beneficial. PMID: 31204560 [PubMed - as supplied by publisher] (Source...

Multiple complications of a 14-year-old hemodialysis catheter.
We describe a case of a 65-year-old woman undergoing hemodialysis treatment since 1986 after a bilateral nephrectomy due to complicated nephrolithiasis. Her last access, two Tesio® tunneled cuffed catheters implanted via the right internal jugular vein functioned correctly for 14 years without complications, and so, was not replaced in the meantime. She was referred to our hospital due to a rupture in a catheter lumen, which was corrected conservatively by creating a more proximal tunnel and excising the affected area. A few weeks later, a new rupture in the same lumen was identified, so the catheter was replace...

The effect of vascular access type on intra-access flow volume during hemodialysis.

Quality assessment of vascular access procedures for hemodialysis: A position paper of the Vascular Access Society based on the analysis of existing guidelines.
In conclusion, there is a weak recommendation in the guidelines on quality control in vascular access surgery. Quality assessment criteria should be defined in this field of surgery. According to these criteria, patients and nephrologists could choose the best vascular access center or surgeon. Centers with best results should be referral centers, and centers with poorer results should implement quality improvement programs.

For patients reliant on haemodialysis, vascular access is a lifeline. Survival differences relating to the type of vascular access are evident and many initiatives have focussed on increasing absolute rates of arteriovenous fistulas and/or decreasing central venous catheter use. While these have achieved some success quantitatively, the qualitative effects are less obvious. The aims of this review article are to explore t...

Intraoperative pneumatic tourniquet use may improve the clinical outcomes of arteriovenous fistula creations.
Authors: Wang S, Wang MS Abstract OBJECTIVES: A major pathology affecting the usability of arteriovenous fistulas for hemodialysis is juxta-anastomosis stenosis. Intraoperative pneumatic tourniquet eliminates the use of vascular clamps, reduces vascular trauma, and may then reduce the juxta-anastomosis stenosis. The aim of this study was to compare the outcomes of arteriovenous fistula creations using the tourniquet-assisted approach versus the clamp-assisted approach.

Semiquantitative analysis of virtual histology derived from intravascular ultrasound images at vascular access stenosis.
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...

Dialysis therapy: Its past, present, and future? My personal recollection of dialysis therapy.
Authors: Ohira S, Kukita K Abstract In Dr Ohira's era, hemodialysis was done using an external arteriovenous shunt. External arteriovenous shunts surely made repeated hemodialysis possible, but they also brought about serious complications which necessarily produced the arteriovenous fistula. Arteriovenous fistula is definitely the most important contribution to long-term survival of the hemodialysis patient. Hemodialysis therapy soon became very common, so that various kinds of patients appeared for it. Then came the era of arteriovenous grafts, because many patients lost good vessels in order to create the arteri...
