When combined with computed tomography, IV DSA is usually of sufficient quality to replace conventional angiography in most patients with abnormalities of the larger intracranial veins and sinuses. Preoperatively, IV DSA can be used to evaluate normal anatomic variations of venous outflow to determine what sinuses can be safely occluded if necessary in the region of the temporal bone, jugular fossa, and base of the skull. Patients with glomus jugular tumors and carotid-cavernous fistulas also need conventional angiograms to define the feeding vessels of these lesions for obliteration by embolization or surgery.
与计算机断层扫描相结合时，静脉数字减影血管造影（IV DSA）的质量通常足以在大多数患有较大颅内静脉和静脉窦异常的患者中替代传统血管造影。术前，IV DSA可用于评估静脉流出的正常解剖变异，以确定在颞骨、颈静脉窝和颅底区域必要时哪些静脉窦可安全闭塞。颈静脉球瘤和颈动脉海绵窦瘘患者也需要传统血管造影来明确这些病变的供血血管，以便通过栓塞或手术进行闭塞。
