Chest wall hematoma after central venous hemodialysis catheter insertion.

There were few case reports discuss about iatrogenic chest wall hematoma. Although it is rare life threatening, it still can result in significant morbidity. A 68-year-old woman with histories of end-stage renal disease under regular hemodialysis and congestive heart failure was sent to our emergency department because of progression of ecchymosis over the anterior chest wall a few hours after hemodialysis. The right subclavian hemodialysis catheter was inserted for hemodialysis on the same day. She did not have a history of bleeding disorders and was not taking any antiplatelet or anticoagulant agents. Additionally, she had no recent trauma episodes. Physical examination revealed a large ecchymosis over the anterior right chest wall with swelling and tenderness. Blood examination showed no specific finding. Contrast-enhanced computed tomography of the chest revealed a hyperdense lesion with extravasation over the right chest wall, suggesting the presence of a hematoma with active bleeding. Local compression was applied. However, hematoma expansion was still noted. Therefore, we consulted a thoracic surgeon concerning surgical intervention. During the operation, active bleeding of the intramuscular arterial branch of the right pectoralis major was encountered. After surgical repair, no more bleeding was noted. It is important to confirm the possible cause of chest wall hematoma. Treating the underlying disease and discontinuing anticoagulation and antiplatelet agents should be considered. For iatrogenic chest wall hematoma, bleeding control should be the priority. Contrast-enhanced computed tomography could be arranged if there are no contraindications.
