- Vascular Access for Hemodialysis
- Ischemic Hand After Vascular Access
- Peripheral Dialysis Access
I. Anatomy and Pathophysiology
1. To know that arterial and venous anatomy involved in the commonly palced grafts and sited for hemodialysis in the upper and lower extremities; know the options for unusual grafts sites when extremities are not available.
2. To know the local and systemic, anatomic effects of creating an arteriovenous fistula for the purpose of hemodialysis .
3. To know the anatomic landmarks for the various routes of access to the circulation for the use of chemotherapy, chronic infusion, obtaining blood samples, and physiologic monitoring.
4. To know the hemodynamic and physiologic effects of creating an arteriovenous fistula; understand the effects of large and small fistulae on the adjacent arteries and veins and on the body as a whole.
5. To know the anatomic and physiologic etiologies for arterial steal, decreased extremity flow and venous hypertension in AV fistulas created for hemodyalysis .
II. Diagnostic Evaluation
1. To know the physical exam and diagnostic tests used in selecting a site for a vascular access including Allen's test, use of duplex screening of veins, and steriogrpahy .
2. To know the diagnostic tests used in evaluating an arteriovenous access with high resistance, poor pressure , thrombosis, and infection.
3. To know the complciatiosn of obtaining access to the central curclation and the diagnostic examinations and tests used to diagnose pneumothorax , misplaced line, pseudoaneurysm , venous thrombosis, and hemorrhage.
4. To know the use of duplex scanning in the evalution of AV accesses.
1. To know the uses and benefits of using autologous or synthetic grafts for the purpose of hemodialysis including the locations, timing of placement, maturation of and longevity of the various access routes and grafts.
2. To know the treatment of complications of arteriovenous fistulas for hemodialysis including infection, steal syndrome, aneurysms, venous hypertension, thrombosis, stenosis , and the failing graft.
3. To know the use of revision, patching, extending, banding, angioplasty and stenting as methods of prolonging AV access.
4. To know the advanteages , techniques and commensurate applications of each route of access to the circulation for the use of administering chemotherapy, chronic infusions, obtaining blood samples and hemodynamic monitoring.
5. To know the complications of the above routes and their treatment.
6. To know the catheter types, their advantages, available for gaining access to the circulation.
7. To know the long term outcome and patencies of the various access types.
