Abstract
A 43-year-old woman, who was diagnosed as having a retroperitoneal tumor, underwent a resection of the tumor, but the intraoperative findings proved resection to be impossible. As a result, only gauze packing was placed in the tumor region in order to stop the massive intraoperative bleeding which had occurred. The patient was thereafter referred to our hospital. After she had sufficiently recovered from the initial surgery, we planned to perform a secondary operation. However, at 5 days after admission, iliac vein thrombus and a pulmonary embolism occurred due to the pressure induced by both the gauze packing and the large size of the tumor. We therefore performed an emergency pulmonary thrombus absorption, and inserted a filter in the inferior vena cava. On the 12th hospital day, we then performed a secondary operation. First of all, we performed anastomosis of the left subclavian artery to an artificial vessel during urgent PCPS. The gauze and the tumor were resected as quickly as possible. After the operation, the quantity of perioperative bleeding was 4367 ml and, as a result, neither an MAP 8 unit blood transfusion nor PCPS was performed. The size of the resected tumor was 19×12×8cm, while its weight was 1099g. The tumor was diagnosed as a solitary fibrous tumor based on the immunohistochemical study results. The patient's postoperative condition has proven to be excellent, and she has survived in a disease-free condition for over 12 months.
