Gluteal compartment syndromes are rare. The pathophysiology and the principles of diagnosis and treatment, however, are the same as those for leg and forearm compartment syndromes. Trauma may not be a salient feature of gluteal compartment syndromes where substance abuse and a prolonged period of unconsciousness, recumbency, or both are more typical. Because of this and the large muscle mass involved, systemic manifestations of a crush syndrome are usually present. Altered mental status and metabolic abnormalities may distract from the primary problem, resulting in delayed diagnosis and treatment. The proximity of the sciatic nerve can result in compression induced neuropathy. Measurement of an elevated compartment pressure confirms the diagnosis. In three patients, aged 37, 31, and 37 years, prompt fasciotomy relieved muscle ischemia, preserved neurologic function, and produced a satisfactory functional result.

Ischemic hepatitis is not an uncommon complication of reversible severe hypotension or cardiac failure. The prognosis usually is determined by the cause of the initial hypotension or cardiac failure, rather than the subsequent hepatic dysfunction. We report a retrospective analysis of nine patients with ischemic hepatitis in which previously unreported clinical and biochemical abnormalities are noted. The clinical and biochemical course of the patients were reviewed until recovery or death from ischemic hepatitis. All the patients had a rapid striking elevation of aspartate aminotransferase, and lactic dehydrogenase, with an equally rapid resolution of these parameters. Abnormal serum glucose levels occurred in six patients (none of whom had a prior carbohydrate intolerance). Insulin therapy was given to three patients for a limited period. Renal impairment was manifest in all nine patients, and it resolved spontaneously within 10 days. Altered mental status was detected in six patients; the changes reverted to normal within 7 days of their onset. A preexisting anemia (hemoglobin less than 11.0 g/dl) was noted on admission in four patients, and it did not appear to potentiate the manifestations of the hepatic ischemia. We conclude that ischemic hepatitis should be anticipated in all patients with a recent history of systemic hypotension. It should be considered in the differential diagnosis of patients with unexplained hepatitis; the early massive rise in lactic dehydrogenase, the rapid fall in transaminases, and the early mild/moderate renal failure strongly suggest ischemic hepatitis. Patients with ischemic hepatitis can manifest reversible renal failure, mental confusion, and hyperglycemia which may require insulin for its control.
