A Large Pleural Effusion following Abdominal Aortic Surgery

Abstract EN

Chylous ascites and coexistent chylothorax is a rare but important complication following retroperitoneal abdominal surgery.

We report a 70-year-old male who developed gradual abdominal distension, chest tightness, and dyspnea five months after having an uncomplicated aortobifemoral bypass performed.

Physical examination was consistent with a large right sided effusion and ascites which were confirmed by computed tomography.

Thoracentesis yielded an opaque milky fluid with analysis consistent with a chylothorax with a paracentesis revealing fluid that was similar in both appearance and biochemistry.

The patient failed initial conservative management so a chest tube was placed followed by chemical pleurodesis.

We review the literature of the pathophysiology and treatment approach to such a pleural effusion.
