内容記述 |
A woman in her 70s underwent her first lumbar spinal fusion (L4-5) for lumbar disc herniation approximately 9 years ago. She underwent a second lumbar spinal fusion (L2-5) because the symptoms recurred. She went into shock intraoperatively and was transferred to another emergency and critical care center; however, the resuscitation efforts were unsuccessful. A forensic autopsy was performed at Yokohama City University to determine the cause of death because medical malpractice was suspected. A postmortem CT scan was performed prior to the autopsy and the radiologist was asked to interpret the CT images. An extensive retroperitoneal hemorrhage noted on CT which was thought to be the cause of death. Although the screw trace was visualized in the L5 spine bony structures, the right L5 pedicle screw was not demonstrated, suggesting that the screw was removed intraoperatively but not re-inserted for unknown reasons. Therefore, the radiologist assumed that removal of the screw caused a large vessel injury. On high-resolution CT images with 1 mm-slice thicknesses the frontal tip of the screw trace was close to the collapsed right common iliac vein. Thus, the radiologist advised the forensic pathologists to meticulously inspect the right common iliac vein. The autopsy revealed a major tear of the right common iliac vein and a large retroperitoneal hematoma, which was determined to be the cause of death. The right common iliac vein also had an ulcer-like lesion near the tear, suggesting the presence of chronic inflammation and adhesions between the vein and the removed screw. Based on these autopsy findings and the additional information from the surgeon that bleeding had occurred from the screw trace upon removal of the right L5 screw, it was concluded that the right common vein tear occurred by strong deviation of the vein into the L5 spine screw trace by chronic inflammation and adhesions. Careful observation of the postmortem CT by experienced radiologists can contribute to accurate autopsies performed by forensic pathologists. |
