Tortuous Vessel

Accordion or concertina effect is the angiographic appearance of pseudostenosis caused by interaction of a stiff guidewire with a tortuous vessel during endovascular procedures. This phenomenon may often mislead the interventionist into performing unnecessary and potentially harmful procedures in a bid to treat the ‘stenotic’ lesion. The resolution of ‘stenosis’ on withdrawal of the guidewire clinches the diagnosis. While well described in coronary vessels, the occurrence of this phenomenon in arteriovenous fistula or graft has not been reported. We describe a case of accordion effect observed during endovascular intervention for arteriovenous graft salvage.

Steal Syndrome

We discuss a case of a 58 year old male who presented for left upper extremity steal syndrome including ischemic monomelic neuropathy (IMN) 1.5 months after arteriovenous fistula creation. He presented after three surgical attempts to salvage his fistula with rest pain, complete loss of function with contracture of the 4th and 5th digits, and loss of sensation in the ulnar distribution for more than three weeks. At our institution, he underwent surgical ligation of the distal fistula and creation of a new fistula proximally, resulting in complete resolution of his vascular steal symptoms almost immediately despite the chronicity prior to surgical presentation. Our patient provides a unique perspective regarding dialysis access salvage versus patient quality of life. The patients’ functional status and pain levels should take precedence over salvage of an arteriovenous access site, and early ligation of the access should be completed prior to chronic IMN development. However, if a patient presents late along the IMN course, we recommend strong consideration of access ligation in order to attempt to regain the full neurovascular function of the extremity as we experienced in our patient.

The Mean

Objectives Percutaneous dialysis access interventions are routinely used to maintain the patency of dialysis access despite the lack of data regarding their long-term effectiveness. This retrospective study was undertaken to study the effectiveness and safety of percutaneous dialysis access interventions in arm fistulas and bridge grafts in an office-based endovascular center. Methods Patients who had a percutaneous dialysis access intervention in their upper extremity access site, performed at a single office-based endovascular center over a nine-year period (2007–2016) were included in this study. The patients’ demographic factors, patency, and complications were analyzed. Patients were entered in the study after first percutaneous dialysis access intervention. Results A total of 298 limbs in 259 patients had 913 procedures carried out over a nine-year period. There were 190 access arteriovenous fistulas and 108 arteriovenous grafts. The two most common arteriovenous fistulas were the brachiocephalic fistula ( n = 74, 39%) and radio cephalic fistula ( n = 69, 36%). Arteriovenous grafts were most commonly placed in the upper arm ( n = 66, 61%) followed by the forearm ( n = 42, 39%). The mean overall patency for all limbs was 50.86 months. Arteriovenous fistulas had a significantly longer patency than arteriovenous grafts (51.65 vs. 42.09 months; P = 0.01). In addition, patients with two or more percutaneous dialysis access intervention in their arteriovenous fistula had significantly greater patency than those with only one percutaneous dialysis access intervention (58.5 vs. 7.6 months; hazard ratio 0.41; P = 0.0008). This was not true for the arteriovenous graft group. Women represented 49% of the patient group. Their accesses had shorter patency than men (39.8 vs. 60 months; P = 0.0007). Conclusions This data support the use of repeated percutaneous dialysis access intervention to maintain long-term patency of dialysis access sites in an office-based endovascular center. Overall, fistulas have longer patency than grafts and women have poorer outcomes as compared to men

Liquid Embolic

N-butyl-2 cyanoacrylate (NBCA) is a liquid embolic material that is widely used in various endovascular procedures because of its permanent and rapid vascular occluding effect regardless of the coagulation profile of the patient. However, NBCA migration to unintended vessels may result in serious complications. This report describes the retrieval of a migrated NBCA cast from the transverse-sigmoid sinus during dural arteriovenous fistula embolization using a transvenous snaring technique.

Innovative Techniques

Background: Conflicting data continue to surround the optimal dialysis access for the elderly. Many propose that catheters are the best option for this population; others emphasize the creation of an arteriovenous fistula. Summary: While an arteriovenous access is the best available access, it has a high early failure rate, particularly in the elderly. However, significant differences exist in forearm (men ≥65 years ~70%; women ≥65 years ~80%) versus upper arm (men ≥65 years ~40%; women ≥65 years ~38%) fistula failure rates in the elderly, with upper arm having much lower failure rates. Two percutaneous innovative techniques that successfully establish fistulas at the upper arm using proximal radial/ulnar ­artery as the inflow have been recently introduced. These procedures have been successfully performed in the elderly. Importantly, these techniques bypass the open surgical exploration and as such avoid the surgical manipulation of the juxta-anastomotic region (a common cause for the development of juxta-anastomotic stenosis and early fistula failure). Key Message: This article discusses the arteriovenous fistula creation in the elderly, highlights the factors necessary for successful fistula creation, and describes the 2 innovative techniques that can be used to provide a robust platform for successful fistula creation in this population.

Interventional radiologists developed and refined the endovascular approaches to maintenance of the permanent arteriovenous vascular accesses that are integral to the provision of hemodialysis for patients with end stage renal disease. As methods of percutaneous arteriovenous fistula creation expand the scope of IR, this chapter reviews the clinical indications and preferences pertinent to dialysis access creation with respect to National Kidney Foundation Recommendations. Accesses remain imperfect, plagued by the development of flow-limiting intimal hyperplastic stenoses, and require monitoring and maintenance to minimize complications, morbidity and mortality. The measures of dialysis access function used in the surveillance of vascular accesses that indicate potential stenosis, and the utility of pre-occlusion recanalization of these stenoses are discussed. Complications specific to dialysis access interventions are also addressed.

Objective: Arteriovenous fistulas are a principal mainstay of long-term dialysis access for patients with end stage renal failure. However, the patency of arteriovenous fistulas is limited, often requiring percutaneous transluminal angioplasty as a salvage procedure. We report a case of percutaneous method of arteriovenous fistula salvage. Methods: A gentleman with brachiocephalic arteriovenous fistula created in 2015 was admitted under us for dialysis access issue. His fistula history was notable for recurrent and refractory venous outflow stenosis of the cephalic vein and the cephalic arch with multiple previous interventions. Ultrasound showed cephalic arch occlusion with high venous pressures. He underwent left brachicephalic fistula percutaneous bypass. We describe the percutaneous creation of a brachial–subclavian arteriovenous fistula via a bypass graft from a worsening brachial-cephalic fistula with cephalic arch occlusion that is not amendable to angioplasty. Results: Final angiogram showed smooth flow to central vein. He is 2 years post procedure, and his fistula remained patent with no interventions required. Conclusion: Percutaneously created jump bypass grafts can reliably produce sustained long-term patency.
