Refractory hypotension and edema caused by right atrial compression in a woman with polycystic kidney disease.
We present the case of a 60-year-old woman with a history of autosomal dominant polycystic kidney disease and long-standing hypertension who developed persistent hypotension. While in the hospital for the treatment of bacteriemia, the patient had low systolic blood pressures (90 to 100 mm Hg), which was thought to be the consequence of infection. After the infection was adequately controlled and the blood pressure did not improve, an echocardiogram was done to further elucidate her hypotension. It was nondiagnostic and revealed an ejection fraction of 70% with left ventricular hypertrophy. Shortly after discharge, she developed significant lower extremity edema and her blood pressure remained low. Due to the low blood pressure it was not possible to mobilize the fluid with her dialysis treatments. A repeat transthoracic echocardiogram at that time revealed that the right atrium was partially compressed throughout the cardiac cycle by polycystic hepatic tissue. This tissue invaginated up through the right hemidiaphragm. A partial liver resection was considered for the patient. Instead, right nephrectomy was performed and the blood pressure improved.
