Evaluation of the Diagnostic and Therapeutic Value of Tissue Ultrafiltration in Patients at Risk of Acute Compartment Syndrome (ACS)

The goal of this clinical trial is to learn if tissue ultrafiltration (TUF) catheters can reduce intramuscular pressure and prevent acute compartment syndrome (ACS) in adults ages 18-60 with severe proximal tibia or tibial shaft fractures. The main questions it aims to answer are: Will intramuscular pressure (IMP) be lower in the TUF cohort compared to controls? Will the consensus likelihood of ACS, incidence of fasciotomy, and 6-month functional outcomes be better in the TUF cohort? Are interstitial fluid biomarkers predictive of ACS? Researchers will compare patients randomized to TUF catheters (n=30) versus control patients receiving standard-of-care only (n=30) to see if TUF lowers ACS risk and improves recovery. Participants will: Be enrolled within 14 hours of injury or prior to high-risk surgery within 48 hours. Receive continuous anterior compartment pressure monitoring. Undergo standard-of-care clinical evaluation and treatment. (TUF arm only) Have three TUF catheters placed in the injured limb to remove interstitial fluid. Return for a 6-month follow-up to assess complications, healing, muscle function, and patient-reported outcomes. (Hennepin Healthcare subset) Provide interstitial fluid samples for biomarker analysis.

The Research About the ACS After Femoropopliteal Arterial Injuries

Crural Compartment syndrome is a well-known sequela after femoropopliteal arterial injuries in the lower extremity, particularly when there has been a long period of ischemia,need for ligation of a major vein, or when there is severe associated soft tissue.There is conteoversy in the treatment.

The Research About Acute Compartment Syndrome

Acute compartment syndrome (ACS) is defined as a clinical entity originated from trauma or other conditions, and remains challenging to diagnose and treat effectively. Threre is the controversy in diagnosing, treating ACS. It was found that there was no criterion about the ACS, and result unnecessary osteotomy. The presence of clinical assessment (5P) always means the necrosis of muscles and was the most serious or irreversible stage of ACS. Besides pressure methods, the threshold of pressure identifying ACS was also controversial.
