Compartmental pressure monitoring after arterial reconstruction lacks clinical relevance

Anterior compartmental intramuscular pressure was studied by the continuous-infusion technique during and after arterial reconstruction of the abdominal or lower extremity vessels in 23 patients. Although there were significant differences between the mean pressures in those patients who had proximal or distal arterial reconstruction, the mean pressure did not increase in the sequential preocclusion, occlusion, and postoperative periods during a mean follow-up of 26 hours in proximal reconstructions and 19 hours in distal reconstructions. One patient had pressures consistent with a borderline compartmental syndrome but died of a ruptured left ventricle before complete correlation of the clinical course and pressures could be made. We conclude from this study that although routine measurement of compartmental pressures during arterial reconstruction of the lower extremities yields interesting findings, it makes no important contribution to the clinical management of the patient.
