Vascular/Transplantation Surgery

About Vascular/Transplantation Surgery Research

What are the subjective and objective improvements following surgery on varicose veins? The effectiveness, durability and cost-effectiveness of endo-vascular intervention on peripheral vascular disease. Combined kidney and pancreas transplantation for Type I Diabetics with end-stage renal failure. These are some of the questions our team are asking to help improve the outcomes of vascular/transplantation surgery.

Vascular/Transplantation Surgery research projects

  • Combined kidney and pancreas transplantation for Type I Diabetics with end-stage renal failure
    • Following kidney and pancreas transplantation, patients have improved renal function and no longer require insulin to control diabetes. The transplanted pancreas may drain into the bladder or small bowel. This study would examine the differences (clinically, biochemically and immunologically) between these different methods of pancreas transplant exocrine management
  • The effectiveness of endo-vascular intervention on peripheral vascular disease
    • Major technological advances have obviated the need for peripheral bypass surgery for many patients. We have a long experience in the introduction of new technology to vascular surgery. The aim of this project is to analyse the outcome of percutaneous vascular procedures for occlusive vascular disease at a patient and limb level, particularly with respect to efficacy, durability and cost-effectiveness in the acute presentation as well as chronic ischaemia.
  • Endoluminal stent graft repair of aortic aneurysms
    • This project is essentially a review of abdominal aortic aneurysm repair by stent grafting since its inception in late 1994. This reviews all patients treated at Southern Health.  Apart from overall review of the experience over the last 15 years or so, this project will also analyse various factors such as the use of balloon expandable stents to reduce Type 1 proximal endoleak, the role of sac coiling in the reduction of endoleak and downward displacement of the stent graft over time, the effect of internal iliac coiling and risk factors associated with buttock ischaemia, ectatic iliac arteries with customised large iliac extension graft and complex stent grafting with customised fenetrated stent grafts and branch grafts.
  • Varicose vein project
    • This project involves analyses of venous disability scoring and the impact of surgery on the subjective and objective improvements following surgery on varicose veins.  The outcomes of surgery will be assessed.
  • CT angiogram comparison with digital subtraction angiography in failing arterio-venous fistula for haemodialysis access
    • This project is in collaboration with the Renal Unit and the Radiology Unit. There is very little data from current literature to support the use of CT angiogram in failing arterio-venous fistula management. This prospective study compares the effectiveness, sensitivity and specificity of CT angiogram with standard digital subtraction angiography and their impacts on further management of AV fistula.
  • Prospective database for Vascular Access in Dialysis Patients
    • This prospective online database aims at providing outcomes including the usefulness of preoperative vein mapping, primary and secondary patencies of AV fistula and types of AV fistula, braciobasilic fistula patency, management strategies on various complications including the cephalic arch segment and central vein stenosis, ischaemic steal and management, role of percutaneous endovascular procedures.
