[Abdominal organ infarction encountered immediately after surgery of primary lung cancer]

Very rare cases of abdominal organ infarction after surgery of primary lung cancer were reported. Case 1: Patient 1 was a 70-year-old man who underwent left upper lobectomy and ND 2a in June 1999 based on the clinical diagnosis of stage IA lung cancer. On the 4th postoperative day, the patient developed fever and right flank pain. Abdominal computed tomography (CT) demonstrated a specific finding compatible with renal infarction. The etiology could not be determined. The patient was treated conservatively. However, severe atrophy of right kidney was demonstrated by following CT performed 3 years later. Case 2: Patient 2 was a 70-year-old woman who underwent left upper lobectomy and ND 2a in December 2002 based on the clinical diagnosis of stage IA lung cancer. On the 4th postoperative day, the patient developed abdominal pain in the left upper quadrant, nausea and vomiting which had lasted for 10 days. Abdominal CT demonstrated a wedge-shaped filling defect at spleen compatible with splenic infarction. The etiology could not be determined. The patient was treated conservatively with prophylactic antibiotic therapy and followed closely. Partial atrophy of spleen was demonstrated by following CT performed 4 months later.
