Development of Acute Pulmonary Edema and Death in Dogs With Aortic Insufficiency Following Renal Artery Constriction

A standardized type of experimental aortic insufficiency was produced in dogs by partial removal of the aortic ‘noncoronary’ valve. A transventricular approach was used to perform the valvulectomies. All dogs with this type of aortic insufficiency, when subjected to renal artery constriction died in 2 days on the average with acute massive pulmonary edema and congestion.

Renal Artery Constriction

Prophylaxis against acute pulmonary edema and death in dogs with aortic insufficiency following renal artery constriction by prior constriction of an atrial septal defect. Dogs with the combined cardiac lesions of atrial septal defect and aortic insufficiency were studied. The atrial septal defects were large and were produced under direct vision. The present studies indicate that when such dogs are subjected to renal artery constriction (RAC) they neither die acutely (within 2 days) nor develop acute massive pulmonary edema. These dogs develop varying patterns of ‘congestive failure’ after RAC. The severity and course of this ‘congestive failure’ seemed to depend upon either the size of the aortic valvular ‘leak’ or the degree of RAC produced in a particular dog.

Life Threatening

Sympathetic crash acute pulmonary edema (SCAPE) is a life-threatening injury, which requires early recognition and intervention to prevent mortality. We present a case of 18-year-old woman with no previous comorbidity, presenting with SCAPE who was successfully resuscitated and eventually diagnosed with renal artery stenosis. Pickering syndrome is a rare cause of hypertensive emergency and should be considered in a young patient presenting with SCAPE in emergency department.
