Arterial compression by an adjacent venous stent graft in a patient undergoing dialysis.

CONCLUSION: This case demonstrates the possibility of arterial compression by an adjacent venous stent graft, especially in a patient with a thin habitus and a brachial-brachial arteriovenous graft. Detailed identification of the outflow vein anatomy before stent implantation is mandatory to avoid such a complication. PMID: 31825299 [PubMed - as supplied by publisher]

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...

DISCUSSION: The factors we have identified as linked to poor outcome may help to identify patients in whom a balloon angioplasty is unlikely to provide a durable outcome. This may prompt exploring alternative treatment or dialysis options at an early stage. PMID: 31084389 [PubMed - as supplied by publisher]

We describe a case of arteriovenous graft outflow stenosis, which led to complete thrombosis of the graft, which was rescued by surgical thrombectomy and stent graft placement across the venous end of the anastomosis with good results.

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...

Authors: Ali H, Attallah K, Awad K, Thabet B Abstract BACKGROUND: To report our experience and evaluate the results of a hybrid procedure comprising of surgical thrombectomy and adjuvant high pressure balloon angioplasty for management of thrombosed arteriovenous grafts (AVGs) with underlying venous anastomotic stenosis. METHODS: Between January 2015 and June 2017, 148 patients with first-time thrombosis of AVGs were considered for treatment with surgical thrombectomy followed by high pressure balloon angioplasty of the underlying venous anastomotic lesions. Monitoring and surveillance was subsequently performe...

This study from Herzog et al (from our own Hennepin County Medical Center) included patients from a national registry and compared 3049 patients on dialysis admitted and eventually found to have acute MI compared with 534,395 patients not on dialysis admitted with an eventual diagnosis of acute MI. Of these groups, only 22% of dialysis patients had an admission diagnosis consistent with acute MI while 43.8% of nondialysis patients had the correct admission diagnosis of acute MI.  Dialysis patients had double the rate of cardiac arrest (11% vs 5%), were less likely to receive reperfusion therapy when eligible (47% vs. ...

In this study, all venous stenoses were treated percutaneously with traditional balloon angioplasty. Although guidelines have not yet recommended drug-eluting balloons for thrombosed fistulas, the superiority of drug-eluting balloons over plain balloons has recently been reported for failed AVFs and arteriovenous grafts.

The objectives of central venous percutaneous transluminal angioplasty are to dilate the venous lesion and to extend the life of arteriovenous fistula for hemodialysis. It is reasonable to perform percutaneous transluminal angioplasty for central venous lesions if this interventional therapy is required to maintain stable dialysis therapy. However, the presence of large fresh thrombus at central venous lesion site represents a contraindication to percutaneous transluminal angioplasty unless the thrombus can first be removed by thrombectomy. Balloon angioplasty is a basic treatment for central venous lesion, but stent impla...

Maintaining vascular access patency represents a tremendous challenge in hemodialysis patients. Although “native” arteriovenous fistula (AVF) is currently recommended as primary vascular access, neointimal hyperplasia stenoses frequently develop, with a risk for AVF thrombosis and vascular access loss. For years, first-line treatment of AVFs stenoses has been percutaneous transluminal angioplasty, generally with high-pressure or cutting uncoated balloons. However, restenosis and reintervention rates remain incredibly high and occur, according to recent studies, in up to 60% and 70% of patients at 6 and 12 months, respectively.
