Summary
A case of graft occlusion due to thrombus in a blind pouch was treated. A covered stent successfully restored graft flow when conventional methods failed.
Area of Science:
- Vascular Surgery
- Interventional Radiology
Background:
- Brachial cephalic fistulas are created for hemodialysis access.
- Conversion to a graft may lead to complications like blind pouch formation.
- Graft inflow occlusion by thrombus is a significant complication.
Observation:
- A patient presented with occlusion of a graft.
- The occlusion was caused by residual thrombus in a blind pouch at the graft inflow.
- Conventional treatments, including Fogarty balloon and angioplasty, were ineffective.
Findings:
- A covered stent was deployed at the graft inflow, covering the thrombus.
- This intervention successfully restored blood flow through the graft.
- Angiographic evidence confirmed the stent placement and flow restoration.
Implications:
- Covered stent placement is a viable endovascular solution for graft inflow occlusion.
- This technique can salvage failing vascular access grafts.
- It offers an alternative to surgical revision in complex thrombotic cases.

01:25Hemodialysis I: Introduction
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...
