Hemodialysis Catheters: Update on Types, Outcomes, Designs and Complications
Semin intervent Radiol 2022; 39: 090-102 DOI: 10.1055/s-0042-1742346Hemodialysis catheters (HDCs) are an essential part of kidney replacement therapy. While these catheters are considered only the bridge to long-term vascular access such as arteriovenous fistulas and grafts, they are associated with significant morbidity and mortality and subsequent increased health care expenditures. However, despite these risks, a large proportion of end stage kidney disease population initiates dialysis using these catheters. The pathogenicity of HDCs stems from its invasive nature to the venous vasculature tree resulting in both mechan...

HeRO Graft: Indications, Technique, Outcomes, and Secondary Intervention
Semin intervent Radiol 2022; 39: 082-089 DOI: 10.1055/s-0042-1742391The Hemodialysis Reliable Outflow (HeRO) graft is a nontraditional, surgical, and endovascularly placed access that offers options in failing arteriovenous fistula/arteriovenous graft or catheter-dependent patients. The HeRO graft provides a unique option and is specifically referred to in the 2019 Kidney Disease Outcomes Quality Initiative (KDOQI) vascular access update. The interventional radiologist has a role and opportunity to work collaboratively with surgeons in assisting with (1) the identification, selection, preparation for, and placement of HeRO...

Stent Graft Outcomes in Dialysis Circuits: A Review of Clinical Trials and Literature
Semin intervent Radiol 2022; 39: 075-081 DOI: 10.1055/s-0042-1742390End-stage renal disease is a prevalent medical condition causing significant problems as the majority of patients are being treated with dialysis. While dialysis provides a means to compensate for the renal impairment, arteriovenous grafts and fistulas are often complicated by neointimal hyperplasia, loss of primary patency, and graft failure. Over the last decade, stent grafts have emerged as an alternative to balloon angioplasty and bare metal stents for revascularization in the event of arteriovenous graft occlusion or stenosis. Several randomized contr...

Devices and Techniques for Percutaneous Creation of Dialysis Arteriovenous Fistulas
Semin intervent Radiol 2022; 39: 066-074 DOI: 10.1055/s-0042-1742381Dialysis treatment for chronic kidney disease was first developed by Dr. Willem Kolff in 1943, and its availability began to grow in 1962 after which it has become a mainstay treatment for patients with chronic kidney disease. It is estimated that, in 2021, 15% of adults in the United States (∼37 million people) have chronic kidney disease, of which 661,000 individuals have renal failure, and 468,000 individuals require dialysis. There have been several advancements in dialysis treatment since its advent, most notably the creation of arteriovenous fistul...

Management of Central Venous Stenosis and Occlusion in Dialysis Patients
Semin intervent Radiol 2022; 39: 051-055 DOI: 10.1055/s-0041-1742152Central venous occlusions (CVOs) of the major intrathoracic veins (jugular, subclavian, brachiocephalic, superior vena cava) can cause debilitating symptoms, negatively impact arteriovenous fistula/graft function, or limit potential access creation options in end-stage kidney disease (ESKD) utilizing hemodialysis (HD). This review summarizes the incidence, pathophysiology, indications/contraindications, and management options of CVOs in the ESKD on HD population and concludes with considerations and examples when planning endovascular central recanalizatio...

Why Peritoneal Dialysis is Underutilized in the United States: A Review of Inequities
Semin intervent Radiol 2022; 39: 047-050 DOI: 10.1055/s-0041-1741080Given a choice, most patients with end-stage renal disease prefer home dialysis over in-center hemodialysis (HD). Peritoneal dialysis (PD) is a home dialysis method and offers benefits such as absence of central venous access and therefore preservation of veins, low cost, and decreased time per dialysis session, as well as convenience. Survival rate for patients on PD has increased to levels comparable to in-center HD. Despite endorsement by leaders in the medical field, professional societies, and those in government, PD has reached only 11% adoption amon...

Complications of Percutaneous Peritoneal Dialysis Catheter
Semin intervent Radiol 2022; 39: 040-046 DOI: 10.1055/s-0041-1741484A functional peritoneal dialysis (PD) catheter is the cornerstone for the success of renal replacement therapy. This success is largely dependent on adhering to best practices during catheter insertion, which starts with a comprehensive preoperative evaluation that helps in determining the catheter configuration type and both entry and exit sites. Additionally, following the best practice guidelines during PD catheter insertion minimizes undesirable complications and provides a durable functional access for dialysis. However, adverse complications are stil...

Patient Selection and Planning for Image-Guided Peritoneal Dialysis Catheter Placement
Semin intervent Radiol 2022; 39: 032-039 DOI: 10.1055/s-0041-1741078Image-guided percutaneous peritoneal dialysis (PD) catheter insertion has become increasingly relied upon to provide urgent access for late presenting kidney failure patients, to overcome surgical backlogs and limited operating room access, to avoid general anesthesia in high-risk patients, and, by itself, as an alternative approach to surgical PD access. Advanced planning for the procedure is essential to assure the best possible outcome. Appropriate selection of patients for percutaneous PD catheter placement, choosing the most suitable catheter type, de...

Peritoneal Dialysis Catheter Placement: Percutaneous and Peritoneoscopic Techniques
Semin intervent Radiol 2022; 39: 023-031 DOI: 10.1055/s-0041-1740940Chronic peritoneal dialysis (PD) is an underutilized renal replacement therapy in treating end-stage renal disease that has several advantages over hemodialysis. The success of continuous ambulatory PD is largely dependent on a functional long-term access to the peritoneal cavity. Several methods have been developed to place the PD catheter using both surgical and percutaneous techniques. The purpose of this article is to describe the percutaneous techniques using fluoroscopy guidance and peritoneoscope method. While fluoroscopic method uses fluoroscopy gu...

Endovascular Management of Thrombosed Dialysis Vascular Circuits
Semin intervent Radiol 2022; 39: 014-022 DOI: 10.1055/s-0041-1740941A functional hemodialysis vascular access is the lifeline for patients with end-stage kidney disease and is considered a major determinant of survival and quality of life in this patient population. Hemodialysis therapy can be performed via arteriovenous fistulas, arteriovenous grafts, and central venous catheters (CVCs). Following dialysis vascular access creation, the interplay between several pathologic mechanisms can lead to vascular luminal obstruction due to neointimal hyperplasia with subsequent stenosis, stasis, and eventually access thrombosis.

KDOQI 2019 Vascular Access Guidelines: What Is New
Semin intervent Radiol 2022; 39: 003-008 DOI: 10.1055/s-0041-1740937The new Kidney Disease Outcomes Quality Initiative (KDOQI) Vascular Access Guidelines have a patient focus for comprehensive vascular access management. The patient's unique circumstances and individualized needs are the foundation of their dialysis access strategy, which is interlinked with the patient's End Stage Kidney Disease (ESKD) Life-Plan. The ESKD Life-Plan is an individualized and comprehensive map for dialysis modalities and vascular access for the lifetime of the patient. New targets are introduced that align with this patient-centered approach...
