Study Evaluating the Safety and Efficacy of Tri-wire Balloon for Treatment of Dysfunctional AV Fistula...

Arteriovenous Fistula

This prospective, multicenter, randomized, controlled study is designed to evaluate the safety and effectiveness of the Tri-wire Peripheral Balloon Dilatation Catheter compared to a standard PTA Catheter in treating subjects presenting with clinical and hemodynamic abnormalities in native arteriovenous (AV) fistulae located in the upper extremity.

Conservative Treatment of Gastrointestinal Fistulas by Endoscopic Injection of tSVFem

Gastrointestinal Fistula

Gastrointestinal (GI) fistula is a complex condition with high mortality and requiring a multidisciplinary management. The aim of this study is to exploit the regenerative-tissue capacities of autologous emulsified adipose tissue-derived stromal vascular fraction (tSVFem, widely used in other medical fields - like plastic surgery -for different purposes) harvested and delivered locally by endoscopy to close the GI fistula. The proposed technique for the treatment of GI fistulas with tSVFem requires a minimal, inexpensive, easily reproducible mechanical manipulation of autologous adipose tissue without necessity of any enzymatic digestion or cell expansion.

Fistulectomy and Primary Sphincter rEconstruction vs. endorectaL Advancement Flap in the Treatment...

Anal Fistula

The optimal method of surgical treatment of complex anorectal fistulas has not been found yet. The aim of this study is to compare two techniques in treatment of high anorectal fistulas. This study purpose to demonstrate that the fistulectomy with dissection from 1/3 to 2/3 of the height of the sphincter complex with primary suturing is technically simpler, equally effective and safe in comparison with muco-muscular endorectal advancement flap.

Dexmedetomidine and Propofol As Sole Sedative Agent for Patients Undergoing Arteriovenous Fistula...

Arteriovenous Fistula

The investigators designed a prospective randomized study to compare the conventionally used sedative drug propofol with a latest alternative dexmedetomidine (DEX), in patients with end-stage renal disease undergoing arteriovenous fistula (AVF) surgery.

A Trial of Interrupted vs Continuous Suturing Techniques for Radiocephalic Fistulae

End Stage Renal Failure

Patients with end-stage renal failure require dialysis to remove toxins from their blood. Haemodialysis is best provided through a native arterio-venous fistula (AVF). Creation of an AVF requires a short (~1hr) surgical procedure to join the artery and vein together. There are limited potential sites for fistula creation. Generally it is preferrable to utilise the most distal sites at the wrist first, as more proximal elbow procedures preclude subsequent use of the wrist should the initial fistula fail. The small diameter of artery and vein at the wrist requires precise surgical technique. There are two potential techniques in common use for creating the arterio-venous anastomosis (the join between artery and vein) - continuous suturing and interrupted sutures. Whilst there are theoretical advantages to the interrupted technique, it is uncertain if these translate clinically into better success of creating the fistula. The aim of this study is therefore to compare the clinical success of the two techniques.

Far Infrared Therapy on AV Fistula Flow, Endothelial Function and Echocardiography in ESRD Patients...

End Stage Renal Disease

Vascular access complications are the leading cause of morbidity in hemodialysis (HD) patients, and are responsible for a significant percentage of hospitalization, with annual costs approaching one billion dollars in the United States. Thrombosis is the most common cause of vascular access failure, and usually develops from stenotic lesions in the venous outflow tract. It has been reported that far infrared (FIR) therapy can improve access flow and unassisted patency of AV fistula, however, the effect of FIR on cardiac function is unknown. The aims of this study are to evaluate (1) the change of access flow of AV fistula and the effect of AV fistula on echocardiographic parameters and (2) the effect of FIR on access flow of AVF and echocardiographic parameters and the serum levels of endothelial markers in patients with end stage renal disease (ESRD) during the first 6 months after the creation of AV fistula.
