BackgroundThis clinical study was conducted to present the clinical features, treatment and outcomes of rectus sheath hematoma (RSH), which is a complication of anticoagulation therapy that can present as acute abdomen.MethodsTwenty-two spontaneous RSH cases who were on anticoagulation therapy were reviewed. Patient characteristics, anticoagulant therapy form and indications, clinical presentation, radiologic work-up, treatment modalities, recurrence, morbidity, and follow-up data were analyzed.ResultsThe majority of the patients were female (64%), and the mean age was 60.6 years. All of the patients (100%) were receiving at least one form of anticoagulation therapy; most (72%) were on warfarin therapy. History of coughing was found in 45% of the cases. The most common presenting signs and symptoms were abdominal pain and mass (77%). International normalized ratio (INR) was >3.0 in all patients on warfarin therapy. The diagnosis was made by abdominopelvic ultrasonography (US) and computerized tomography (CT). CT showed 100% sensitivity. The majority of patients (87%) were treated conservatively. Three patients (13%) were operated and 2 patients (9%) died as a result of RSH. Two patients experienced recurrence in one year.ConclusionRSH should be suspected in elderly, coughing patients on anticoagulation therapy, who present with clinical manifestations of acute abdomen. Early diagnosis can help to avoid increased morbidity or unnecessary surgical intervention.
