Reconstructive Surgical Management of Vasopressor-Ischemia Related Distal Extremity Loss

Area of Science:

• Reconstructive Microsurgery
• Limb Salvage Surgery
• Trauma Surgery

Background:

• Severe sepsis and septic shock often necessitate vasopressor use, which can lead to distal extremity ischemia.
• While limb salvage is not the initial priority in critical illness, vasopressor-induced ischemia can result in partial extremity loss, posing complex reconstructive challenges.

Observation:

• A 48-year-old male with a history of septic shock experienced dry gangrenous partial loss of upper and lower extremities, including the left thumb and right foot.
• The patient underwent thumb reconstruction using pollicization of the index finger and a reverse radial forearm flap.
• Foot salvage involved orthopedic procedures and a free neurotized anterolateral thigh (ALT) flap with nerve coaptation.

Findings:

• Successful thumb reconstruction was achieved through pollicization, restoring prehensile function.
• Foot salvage was accomplished using a free neurotized ALT flap, providing sensate reconstruction.
• The case highlights challenges such as flap survival and the necessity of multidisciplinary approaches.

Implications:

• This case demonstrates a viable reconstructive strategy for vasopressor-induced distal extremity loss.
• The techniques presented can help restore function and sensation in severely compromised extremities.
• This approach offers hope for limb salvage in complex cases previously considered unsalvageable.
