Massive Hemoperitoneum Secondary to Splenic Laceration After Extracorporeal Shockwave Lithotripsy.

Extracorporeal shock wave lithotripsy (ESWL) is considered a safe technique, but not without complications, though the vast majority are minor complications. We describe a rare case of splenic injury after ESWL. A 33-year-old male presented to the emergency department (ED) after three weeks experiencing severe intermittent left-sided flank pain that he contributed to a previous motor vehicle accident. Then computerized tomography (CT) revealed a left renal stone. ESWL was performed after three weeks. After being discharged home, he returned the same day to the ED with persistent, worsening abdominal pain, hypotension, and multiple syncopes. CT demonstrated the presence of active contrast extravasation from the spleen likely due to active bleeding. Initial resuscitation was with intravenous fluids and blood products. The following day, the embolization of the splenic artery was done. The patient was discharged home after nine days of conservative management. After one month, he had shortness of breath due to a large left-sided pleural effusion and lung collapse managed with thoracocentesis and thoracoscopic surgery. Subsequent follow-up reveals much improvement and successful conservative management. Splenic injury is a rare complication of ESWL, and all of the 11 reported cases in the literature were managed with splenectomy. Our case is unique in being successfully managed conservatively.
