What Is Microvascular Surgery?
Microvascular surgery focuses on repairing tiny blood vessels and is often combined with microsurgical repair of nerves and soft tissues in complex injuries.
It is also used in reconstructive procedures to transfer healthy tissue from one area of the body to another.
With advanced microscopes and delicate tools, our microvascular surgeon in Houston reconnects blood vessels, often a few millimeters in diameter. This meticulous repair restores blood circulation, which supports tissue survival and proper healing.
Common Conditions Our Microvascular Surgery Specialist Treats
Microvascular surgery is important for treating many conditions that affect the hand and upper extremity, such as:
- Traumatic amputations of the finger or hand
- Severe cuts that affect arteries and nerves
- Complex fractures with associated injury to the blood vessel
- Loss of soft tissue that needs tissue transfer
- Reconstructive surgery following infection or after removing a tumor
What to Expect During Microvascular Surgery?
Microvascular surgery is done while you are under anesthesia and can take several hours, depending on how complex the injury is.
Our surgeon uses special microscopes to find and reconnect damaged blood vessels and nerves with very fine stitches. This helps restore blood flow and improves the likelihood of successful tissue healing.
After surgery, we carefully check your blood flow to make sure everything is working as it should. You may need rehabilitation therapy to help you regain movement and strength. Our microvascular surgery specialist will give you detailed post-operative guidance and follow-up care to help you recover.
