The intercavernous sinuses (ICSs) connect the cavernous sinuses on both sides. Although the management of ICSs is an important aspect in extended transsphenoidal surgery (eTSS), there has been no report to evaluate ICSs in sellar lesions. In this study, we analyzed ICSs using computed tomographic digital subtraction venography (CT-DSV) in sellar lesions.
We retrospectively analyzed ICSs in 52 cases of pituitary adenoma and 13 cases of tuberculum sellae meningioma using CT-DSV.
In pituitary adenomas, the detection rate of ICSs was lower than that of normal sellae controls. When the tumor volume of pituitary adenomas was greater than 5 ml, we could not detect any ICSs. In tuberculum sellae meningiomas, the detection rate of the anterior intercavernous sinus was high, but this finding was not significant. Meningioma tumor sizes did not have any influence on ICSs.
CT-DSV can be useful for evaluating ICSs in sellar lesions. Preoperative evaluation of ICSs may provide important information for eTSS.
海绵间窦（ICSs）连接双侧海绵窦。尽管在扩大经蝶窦手术（eTSS）中，海绵间窦的处理是一个重要方面，但尚无关于评估鞍区病变中海绵间窦的报道。在本研究中，我们使用计算机断层扫描数字减影静脉造影（CT-DSV）对鞍区病变中的海绵间窦进行分析。
我们使用CT-DSV对52例垂体腺瘤和13例鞍结节脑膜瘤患者的海绵间窦进行回顾性分析。
在垂体腺瘤中，海绵间窦的检出率低于正常鞍区对照组。当垂体腺瘤的肿瘤体积大于5 ml时，我们无法检测到任何海绵间窦。在鞍结节脑膜瘤中，海绵间前窦的检出率较高，但这一发现无统计学意义。脑膜瘤的肿瘤大小对海绵间窦没有任何影响。
CT-DSV可用于评估鞍区病变中的海绵间窦。术前评估海绵间窦可能为扩大经蝶窦手术提供重要信息。
