Summary
Spasms in groin flaps during free transfers can cause complications. This study identifies four spasm types and evaluates methods to assess blood circulation and local medications to manage spasms.
Area of Science:
- Vascular Surgery
- Microsurgery
- Experimental Surgery
Context:
- Free tissue transfers, particularly groin flaps, are crucial in reconstructive surgery.
- Neurotized flaps aim to restore sensation and function.
- Vascular pedicle spasms are a known complication that can compromise flap viability.
Purpose:
- To identify and classify different types of vascular spasms observed in neurotized groin flaps during free transfers.
- To develop and present a method for assessing blood circulation within the flap.
- To evaluate the efficacy of local medications in mitigating vascular spasms and improving flap perfusion.
Summary:
- Four distinct types of vascular spasms were identified in neurotized rat groin flaps: segmental artery spasm, whole artery spasm, flap artery spasm affecting circulation, and tissue shock involving pedicle spasm.
- A method to quantify blood flow through the flap was established.
- Local administration of Mesocain, Marcain, and Solutio Vischnjevskij was tested for their spasmolytic effects.
Impact:
- Understanding these spasm types can lead to improved surgical techniques for free flap transfers.
- The developed assessment method aids in real-time monitoring of flap perfusion.
- Findings on local medications offer potential strategies to reduce flap complications and improve outcomes in reconstructive microsurgery.
