Summary
Arteriovenous fistulae are abnormal connections between arteries and veins. This case report details a rare instance of an arteriovenous fistula developing after anterolateral thigh free flap transfer in hand surgery.
Area of Science:
- Vascular Surgery
- Microsurgery
- Hand Surgery
Background:
- Arteriovenous fistulae (AVFs) are abnormal connections between arteries and veins, bypassing capillary circulation.
- AVFs can lead to complications due to altered blood flow.
- Their occurrence after microsurgical procedures is uncommon.
Observation:
- A patient developed a spontaneous arteriovenous fistula.
- This occurred following a free transfer of an anterolateral thigh flap.
- This represents a rare complication in free flap surgery.
Findings:
- The study presents the first reported case of an arteriovenous fistula arising in a free flap specifically within hand surgery.
- Previous reports documented AVFs after replantation and head and neck free flaps.
Implications:
- This case highlights a previously undocumented complication of free flap surgery in hand reconstruction.
- Awareness of this potential complication is crucial for microsurgeons.
- Further investigation into the etiology and management of AVFs in free flaps may be warranted.

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...
01:26Aneurysm III: Interprofessional Care
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. This...
