Active clinical trials for "Fistula"

Isometric exercise has been shown to increase the diameter and the blood flow rate of forearm veins.At present, more studies focus on the perioperative period to promote the maturation of arteriovenous fistula(AVF), while there are few reports on functional maintenance measures for the patients with maintenance hemodialysis.This study aims to explore the effect of dumbbell exercise on AVF，and evaluate whether patients can carry a 6-pound item with the fistula limb in a reasonable way.

Autologous ADSVF constitutes an innovative therapeutic strategy that concentrates various types of regenerative stem cells and paracrine factors able to promote angiogenesis and tissue repair. Together with the ease of collection from a minimally manipulated lipoaspirate, the unique properties of ADSVF offer new opportunities for fistulas' healing in patients with CD. The use of ADSVF is currently developed in many clinical fields based on safety and efficacy data. Our ADICROHN pilot study evaluating safety and tolerance of local administration of autologous ADSVF with microfat in CD patients with complex perianal fistula refractory to conventional medical and surgical therapy showed that this novel therapeutic approach appears feasible and safe. However the therapeutic potential of local this combined treatment in healing refractory perianal Crohn's fistulas still remains to be demonstrated. The main objective of this study is to assess the efficacy of local injection of autologous ADSVF and microfat versus placebo for the treatment of complex refractory perianal Crohn's fistulas at week 24. The efficacy will be assessed on clinical assessment of closure of all the external openings that were drained at baseline, and MRI confirmation of absence of collections > 2 cm of the treated perianal fistulas at week 24.

Objectives: Primary Evaluate the primary operator usability of VSI streaming software for realtime streaming of images from video capture devices to a head mounted display (Hololens 2) during Interventional Radiology procedures Secondary Evaluate Radiographer usability of VSI streaming software. Develop suggestions for future research studies to assess the safety and efficacy of the VSI streamer software during other Interventional radiology procedures Evaluate the impact of VSI streaming software on room setup time, procedural time and fluoroscopy time Assess the feasability of remote collaboration by real time image transmission between remote devices through 3D telemedicine

Evaluation of the anesthetic quality and analgesic efficacy of adding ketamine to intrathecal bupivavaine in selective saddle block for perianal surgery.

This study will investigate the effect of pre-operative exercise on hemodynamics in the fistula artery and vein, Pre and Post Arteriovenous Fistula Formation as well as the suitability of Cannulation of Arteriovenous Fistula at 12 weeks Post Surgery. This is a randomised control study with 20 patients each in the Control arm (Group A) or the Exercise arm (Group B). The subjects will be randomised into 1:1 into one of the two groups. The patients will have an ultrasound doppler vein mapping done prior surgery and the necessary follow up visits.

Arteriovenous fistula (AVF) is considered the gold standard for safe and effective vascular access during hemodialytic treatment. It is known that systemic aerobic exercise is capable of promoting peripheral vasodilation, however, its effects on AVF are unknown. For this reason, we will evaluate the effects of aerobic exercise on a stationary bicycle over the AVF caliber.

Objective: To analyze the effect of neuromuscular electrostimulation in the maturation of radiocephalic arteriovenous fistula (RC-AVF) patients with chronic kidney disease (CKD) stage 5-5D Design: Clinical Trial with medical devices, 18-month, single-center, within the hospital setting. Disease or disorder study: vascular Access maturation. Population: Patients with CKD stage 5-5D at the research center. Project duration: 78 weeks Methodology: Patients with CKD stages 5-5D that has undergone a native AV in service stations to give their informed consent and meeting the inclusion criteria will be included. At baseline two study groups were established: Group 1: neuromuscular electrostimulation Group 2: isometric exercises

Urinary fistulas are unfortunately one of the most common post operative complications in hypospadias repairs and bladder neck transections on pediatric and adult populations, an estimated 20%, resulting in multiple repeat operations with prolonged hospitalization. The negative sequelae of these fistulas have significant financial and psychosocial impact and the aim of this study is to evaluate if the fresh frozen preserved amniotic membrane tissue studied, which have live cells and intact naturally occurring growth hormones and peptides that augment healing that have been shown in early studies to be effective facilitating previous failed fistula repairs and leg ulcer healing, respectively, will help reduce the incidence of urinary fistulas in subject populations.

This is an observational study assessing the impact of conventional dose iodinated contrast on the renal function of advanced chronic kidney disease patients undergoing arteriovenous fistula evaluation using a standard sodium bicarbonate prophylaxis protocol. In addition, this model allows for pre and post procedure measurements of kidney function, providing a unique opportunity to assess the utility of novel biomarkers for contrast-induced kidney injury. Our primary hypothesis is that there will be no change in serum creatinine post-procedure when using a standard sodium bicarbonate prophylaxis protocol. Our secondary hypothesis is that there will be no change in urinary kidney-injury marker-1 (KIM-1) post-procedure using a standard sodium bicarbonate prophylaxis protocol. In addition, we will assess the impact of different patient characteristics on the development of contrast-induced kidney injury, such as diabetes, coronary artery disease, hypertension, and angiotensin converting enzyme inhibitor therapy.

The objective of this registry is to collect observational data under local standard of care and evaluate safety and performance of the Serranator® Alto in treatment of peripheral artery disease (PAD), or dysfunctional native or synthetic arteriovenous dialysis fistulae in a real-world scenario.
