Acute Pulmonary Edema Due to Arteriovenous Shunt Placement After Lung Transplantation.

Lung transplant recipients often have complications of immunosuppressant-induced nephropathy, which may require renal replacement therapy. We report a case of unilateral lung edema and pulmonary hypertension due to arteriovenous fistula placement in a patient with unilateral chronic lung allograft dysfunction after bilateral living-donor lobar lung transplantation. Lung transplant recipients with limited residual vascular beds, such as lobar graft or severe deviation in lung perfusion, are vulnerable to the acute increase in blood flow due to arteriovenous fistula placement and pulmonary edema can easily develop regardless of the left ventricular function. Hence, careful volume control is required.
