Filter by:Arterio-Venous Fistula (AVF) is the most recommended vascular access for hemodialysis. Steal syndrome is a potential complication of AVF implantation and occurs secondary to diversion of the arterial flow of a limb to the venous system resulting in limb ischemia. Measuring wrist pressure compared to arm pressure before and after fistula implantation can be a suitable tool in predicting the possibility of Steal syndrome. In this study, the ratio of wrist to arm pressure and its relationship with Steal syndrome symptoms before and after fistula implantation are investigated.
The aim of this work was to compare primary failure rates and the primary functional patency of one-stage vs two stage brachiobasilic fistulas to compare the two surgical techniques .
The aim of this study is to evaluate the role of stellate ganglion blockade (SGB) for preserving arteriovenous fistula in hemodialysis patients undergoing major lower limb orthopedic surgery.
The purpose of this study is to identify functional vascular changes and clinical factors correlated with the occurrence of short- or medium-term hand ischaemia after arteriovenous fistula creation.
Arteriovenous fistulas (AVF) are considered essential and the primary vascular access for end-stage renal disease patients to receive hemodialysis (HD) treatment. The maturation failure rate of AVFs is approximately 23%. The aim of our study is to compare intraoperative fistula flow and measurements of vascular structures' diameters with postoperative fistula maturation, following the completion of the fistula operation, to reveal the relationship between them. Providing insights into the need for intraoperative intervention and/or postoperative fistula management based on these measurements is intended to contribute to the literature by offering predictions and perspectives.
It was conducted to investigate the effect of ice application to the kaleidoscope and hoku point on the management of cannulization-related pain in patients receiving hemodialysis treatment.
The objective of this prospective，multi-center，single arm study is to obtain further data on the safety and performance of the Acotec Orchid＆Dhalia Drug-coated Balloon catheters for the treatment of for the obstructive lesions in the native Arteriovenous Dialysis Fistulae (AVF).
This study is a retrospective cohort study aimed at evaluating the impact of autologous arteriovenous fistula (AVF) on the heart, especially the left atrial structure, in patients with end-stage renal disease (ESRD) through a retrospective cohort study. The aim is to further clarify the relationship between the establishment of AVF and the occurrence of atrial fibrillation, and provide a theoretical basis for exploring the relevant mechanisms of AVF induced atrial fibrillation in the future.
This is a prospective, multi-center, two-arm, randomized trial to quantify the performance of the EchoMark®/EchoSure® System for AVF diagnostic ultrasound when used under a protocol of biweekly use for assessing fistula maturation and reducing time to Clinical Maturation.
The main objectives of this observational study are to compare the results of the sonographic parameter hand acceleration time (HAT) measured before and after creating an arteriovenous fistula (AVF) for hemodialysis and assess if it is associated with the incidence of hemodialysis access-induced distal ischemia (HAIDI). The secondary objectives are to study the incidence of HAIDI in patients intervened for the creation of an AVF in the last 6 months, study the AVF permeability at 6 months, and study the AVF-related complications at 6 months.
