Microvascular Surgery

Microvascular Surgery in Westminster, California

Microvascular surgery is performed on very small blood vessels, typically 3 to 5 millimeters in diameter, using an operating microscope, specialized surgical instruments, and tiny needles with ultrafine sutures.

Microvascular surgery is used to reattach severed fingers, hands, arms, and another amputated parts to the body. This is done by reconnecting the small blood vessels, thus restoring circulation before the injured tissue begins to die. Microvascular is also used in reconstructive surgery.

The transplanted healthy tissue from a distant site is called a “free flap”. This healthy tissue is moved to the site of the wound where blood circulation is restored.
