Filter by:Many older adults require hemodialysis for advanced chronic kidney disease, but it is not clear which permanent vascular access method (fistula or graft) is best with respect to access effectiveness and patient satisfaction. In this pilot study, the study team will test the hypothesis that older adults undergoing graft access placement will more effectively transition from catheter-based to arteriovenous access-based hemodialysis; have fewer following vascular access procedures; have better upper extremity function; have better self-sufficiency with daily activities; and better health-related quality of life compared to those who undergo arteriovenous fistula access placement. The study will establish feasibility of randomizing older adults to the two types of arteriovenous access surgeries; evaluate relationships between measurements of pre-operative physical function and vascular access development; compare vascular access outcomes between the two groups; and gather longitudinal assessments of upper extremity muscle strength, performance of activities of daily living, and patients' reports of satisfaction with their vascular access and quality of life.
Our objective is to validate the CT / MRI combination of non-injected rock for the rapid positive diagnosis of perilymphatic fistulas.
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.
Colovesical fistulas are well-recognized but relatively uncommon pathology to both the general and colorectal surgeon. It is a complication arising from an underlying primary acute to chronic inflammatory process. Although colovesical fistulas are uncommon, they are associated with significant morbidity, affect quality of life, and may lead to death, usually secondary to urosepsis. Early diagnosis and management is essential. The purpose of the study is to determine the objective use of cystographic evaluation on postoperative day two to guide early Foley catheter removal post colovesical fistula takedown. The hypothesis is that a cystogram showing no extravasation of contrast on postoperative day two will predict safe removal without increased morbidity. This is an uncontrolled, single arm trial. Patients who meet criteria to undergo either minimally invasive or open colovesical fistula takedown with sigmoid colectomy, without evidence of the need for bladder repair will be eligible to participate. An indwelling Foley catheter is placed intraoperative and continued postoperative. All patients who consent to participate would undergo a cystogram on postoperative day two. The cystogram will be conducted by a radiologist and technician well-trained in the techniques and interpretation of the study. The colorectal surgery enhanced recovery protocol will be followed on all patients with the exception of the cystogram being conducted on post-op day two. If there is no evidence of extravasation of dye is seen on the cystogram the Foley catheter will be removed. Patients will be monitored closely following catheter removal to ensure self-diuresis.
The aim of the present prospective study was, first, to verify the correlation between biliary colonization and postoperative infectious complications, and secondarily to asses morbidity and mortality for patients who underwent pancreaticoduodenectomy. The hypothesis is that a proportion of post-operative infections after pancreaticoduodenectomy is due to bacteria that colonize the bile ducts during the preoperative period.
The purpose of this study is assessment of safety, efficacy, and short-term outcome of SQUID™ in the embolization of Dural Arteriovenous Fistula
This prospective, global, multicenter, single arm post-approval study is designed to investigate the clinical use and safety of the Lutonix® 035 AV Drug Coated Balloon (DCB) PTA Catheter in subjects presenting with clinical and hemodynamic abnormalities in native arteriovenous (AV) fistulae located in the upper extremity.
This trial aims to determine if intra-operative use of human dehydrated amnion chorion allograft improves post-operative patient healing outcomes.
The primary objective of this study is to demonstrate that mucous fistula refeeding between enterostomy creation and enterostomy closure reduces the time to full enteral feeds after enterostomy closure compared to standard of care.
This study is a prospective, multicenter, single-arm study. Patients with Dural Arteriovenous Fistulas (dAVF) have a few choice for safe treatment. In this study, all patients with qualifying dAVFs will be treated with PHIL® Liquid Embolic material.
