PURPOSE We aimed to evaluate the safety and effectiveness of percutaneous transluminal angioplasty (PTA) for dysfunctional femoral arteriovenous graft and analyze clinical or anatomic predictors of graft patency. METHODS The records of 45 patients who underwent PTA or thromboaspiration for dysfunctional or thrombosed femoral arteriovenous graft from 2005 to 2012 were reviewed retrospectively....

BACKGROUND Although ultrasonography before a vascular access (VA) operation has become popular in recent years, benchmarks for the diameter or blood flow of arteries or veins are not defined in Japan. The objective of the present study is to analyze the relationship between preoperative US findings and the patency rate of VA in Japanese hemodialysis patients. METHODS 139 patients with end sta...

BACKGROUND AND OBJECTIVES Vascular access standards are predominantly based on older, single-center reports; however, the hemodialysis population has changed dramatically and primary arteriovenous fistula failure is a huge problem. This prospective, multicenter study used standardized definitions to analyze patency rates and potential risk factors that affect functional patency and late arterio...

UNLABELLED The incidence of vasal injury during inguinal herniorrhaphy is estimated at 0.5%. We sought to assess the patency rates and long-term fertility outcome after microsurgical repair of vasal obstruction related to prior inguinal herniorrhaphy. METHODS Twenty procedures were performed on 13 men diagnosed with infertility and vasal injury secondary to previous inguinal herniorrhaphy. Ei...

 Abstract Background: The optimal therapy of acute iliofemoral venous thrombosis is still a matter of debate. The purpose of our study was to evaluate the late results of iliofemoral thrombectomy with regard to the prevention of the development of a Post Thrombotic Syndrome (PTS). Methods: During 2000-2003, 18 patients underwent transfemoral venous thrombectomy for acute iliofemoral venous thro...

This study was a retrospective analysis of the efficacy of thrombectomy plus local catheter-directed thrombolysis (CDT) for the treatment of lower extremity deep venous thrombosis (LDVT). The experimental group underwent thrombectomy plus LCDT, whereas the control group underwent thrombectomy plus systemic thrombolysis via the dorsalis pedis vein. Venography and vascular color Doppler ultrasoun...

BACKGROUND Robotic-assisted coronary artery bypass grafting (CABG) has been shown in short-term studies to increase patient satisfaction and to reduce surgical morbidity and recovery times. However, the long-term patency rate of robotic-assisted CABG is unknown. Therefore, the objective of this study was to assess the long-term patency rate of robotic-assisted coronary artery bypass grafts. M...

patients with end stage renal disease need a good vascular access for hemodialysis. arteriovenous fistula is the method of choice for vascular access in these patients. however, failure of arteriovenous fistula due to thrombosis is a major problem. the aim of this study was to evaluate the effect of the heparin on the patency of the arteriovenous fistula. this prospective interventional case co...

OBJECTIVE This study explored the long-term outcomes of arteriovenous fistulas treated with vonapanitase (recombinant human elastase) at the time of surgical creation. METHODS This was a randomized, double-blind, placebo-controlled trial of 151 patients undergoing radiocephalic or brachiocephalic arteriovenous fistula creation who were randomized equally to placebo, vonapanitase 10 μg, or von...

BACKGROUND Patency of the revascularization conduit is an essential predictor of long-standing survival after coronary artery bypass grafting. OBJECTIVES We have conducted this study to compare the mid-term patency rates of radial artery (RA), left internal thoracic artery (LITA) and also saphenous vein (SV) grafts in asymptomatic patients following coronary artery bypass graft surgery (CABG)...
