Vascular complications remain a major cause of graft loss after pancreatic transplantation. They include vascular thrombosis, pseudoaneurysm, and arteriovenous fistula (AVF). We report a case of an AVF that appeared 3 months after a simultaneous pancreas-kidney transplantation (SPKT). Doppler ultrasonography followed by magnetic resonance angiography and later angiography provided a definitive diagnosis of a mesenteric AVF. An endovascular approach is becoming the treatment of choice owing to the high risk of graft loss associated with open surgical correction. Microcoils alone, or in conjunction with detachable balloons, are frequently used; still, a new generation of vascular plugs seem to offer a therapeutic option for AVF closure, because it is a "1 shot" procedure that avoids the risk of accidental coil migration. A new-generation Amplatzer Vascular Plug 4 was deployed over the distal arterial branch of the superior mesenteric artery stump, leading to complete exclusion of the AVF and restoring normal vascular flow.

Background: Maintenance hemodialysis (MHD) is an effective treatment for patients with end-stage renal disease. Although MHD can prolong the survival of patients, their quality of life is lower and the fatality rate is higher. This work analyzed the factors related to the autogenous arteriovenous fistula (AVF)-like expansion of non-diabetic MHD patients by vascular ultrasound (VUS).

Expansion of home hemodialysis (HHD) provides an opportunity to improve clinical outcomes, reduce cost of care, and address the staffing challenges currently faced in caring for patients with kidney failure on replacement therapy. To increase HHD expansion, current practices and barriers to home dialysis must be examined and addressed. One such barrier is vascular access for HHD; although tunneled hemodialysis central venous catheters (CVCs) have been used for decades, physicians still hesitate to send patients home without a mature, functional arteriovenous access.

Angiosarcoma is a rare and aggressive malignant tumor arising from vascular or lymphatic endothelial cells. Angiosarcoma at an arteriovenous fistula site is exceptionally rare. We report a case of a 37-year-old male renal transplant recipient who developed a high-grade epithelioid angiosarcoma at the site of an arteriovenous fistula six years post-transplant.

This article presents the rationale, challenges, and adaptive strategies employed during the initiation and execution of the arteriovenous (AV) access trial-a multicenter randomized controlled trial (RCT) comparing AV fistulas and AV grafts for hemodialysis in older adults with major comorbidities. Motivated by shifts in epidemiologic landscapes and evolving guidelines moving away from a fistula-first approach and to more patient-centric approaches, the objective of this randomized controlled trial was to fill critical knowledge gaps in determining the optimal vascular access for this complex patient population. We outline the challenges encountered in patient recruitment along with measures employed to overcome these obstacles in recruitment.

Arteriovenous grafts (AVG) can be the only bailout solution for patients who require kidney replacement therapy but are unsuitable for arteriovenous fistula (AVF) creation. Currently, high-level evidence on the effectiveness and safety of antithrombotic therapy in AVG patients is scarce. Following the PICO (patient; intervention; comparator; outcome) model and the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, a data search of the English literature in PubMed, SCOPUS, Central Cochrane was conducted, until March 1st, 2023 (PROSPERO Protocol Number: CRD42023401785).
