Summary
A delayed arteriovenous fistula (AVF) presented 25 years after a stab wound, causing leg swelling. Endovascular repair with a covered stent proved effective for this rare condition.
Area of Science:
- Vascular Surgery
- Interventional Radiology
Background:
- Arteriovenous fistulas (AVFs) can arise from trauma.
- Delayed presentations of AVFs are uncommon.
Observation:
- A 64-year-old female presented with unilateral leg swelling and a popliteal artery bruit.
- History revealed a stab wound 25 years prior.
- Arterial duplex ultrasound confirmed a posterior tibial artery-vein AVF.
Findings:
- Successful endovascular management of the AVF was achieved using a covered stent.
- This case demonstrates a rare delayed presentation of a traumatic AVF.
Implications:
- Highlights the potential for late-onset AVFs after seemingly minor trauma.
- Emphasizes the efficacy of endovascular techniques for managing complex AVFs.
- Suggests considering remote trauma in the differential diagnosis of unexplained vascular abnormalities.

01:25Hemodialysis I: Introduction
1.0K
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...

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

201
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
