In a few cases, postmortem computed tomography angiography (PMCTA) is effective in postmortem detection of cortical artery rupture causing subdural hematoma (SDH), which is difficult to detect at autopsy. Here, we explore the usefulness and limitations of PMCTA in detecting the sites of cortical arterial rupture for SDH. In 6 of 10 cases, extravascular leakage of contrast material at nine different places enabled PMCTA to identify cortical arterial rupture. PMCTA did not induce destructive arterial artifacts, which often occur during autopsy. We found that, although not in all cases, PMCTA could show the site of cortical arterial rupture causing subdural hematoma in some cases. This technique is beneficial for cases of SDH autopsy, as it can be performed nondestructively and before destructive artifacts from the autopsy occur.
在少数情况下，尸检计算机断层血管造影（PMCTA）对于尸检时难以检测到的导致硬膜下血肿（SDH）的皮质动脉破裂的死后检测是有效的。在此，我们探讨PMCTA在检测SDH皮质动脉破裂部位方面的有用性和局限性。在10例病例中的6例中，造影剂在9个不同部位的血管外渗漏使得PMCTA能够识别皮质动脉破裂。PMCTA不会诱发在尸检过程中经常出现的破坏性动脉伪影。我们发现，虽然并非在所有病例中，但PMCTA在某些情况下能够显示导致硬膜下血肿的皮质动脉破裂部位。这项技术对SDH尸检病例有益，因为它可以在尸检产生破坏性伪影之前以非破坏性方式进行。
