Sinus pericranii is a vascular anomaly with extra- and intracranial venous connections. Sinus pericranii is categorized into 2 groups according to its contribution to the normal venous circulation. The accessory type sinus pericranii, which does not contribute to the normal major venous circulation, can be managed. Despite several proposed operative maneuvers, a standardized technique is yet to be established to control intraoperative bleeding.
A 2-week-old neonate underwent examination of a subcutaneous mass in the parieto-occipital region. The subcutaneous mass had a major venous connection to the superior sagittal sinus on ultrasonography. The subcutaneous mass was partially thrombolized on magnetic resonance imaging and was minimally enhanced on computed tomography venography. The subcutaneous mass seemed not to contribute to the normal venous circulation. Surgical removal of the subcutaneous mass was performed due to its increased size at the age of 1 year and 3 months. While subcutaneous mass was detached from the scalp, the major venous connection was manually compressed, and minor venous connections were easily detected. The intraoperative bleeding was controllable. The pathological diagnosis was sinus pericranii. The patient is now followed up in the outpatient clinic. No recurrence was seen 18 months after the surgery.
DISCUSSION/CONCLUSION: Intraoperative hemostasis is essential while sinus pericranii is detached from the cranium. Hemostatic agents such as bone wax or absorbable gelatin and heat coagulation seem to be useful. However, complicative hemorrhage concerning to the preceded technique has been also reported. As seen in our case, to detect minor shunting points between the sinus pericranii and the intracranial veins, the major venous connection was manually compressed. Intraoperative manual compression of a major venous connection of sinus pericranii can be an option to manage intraoperative bleeding.
颅骨膜窦是一种具有颅外和颅内静脉连接的血管异常。颅骨膜窦根据其对正常静脉循环的作用分为两组。不参与正常主要静脉循环的副类型颅骨膜窦可以进行处理。尽管提出了几种手术操作方法,但尚未建立控制术中出血的标准化技术。
一名2周大的新生儿接受了顶枕部皮下肿块的检查。超声检查显示皮下肿块与上矢状窦有主要静脉连接。磁共振成像显示皮下肿块部分血栓形成,计算机断层静脉造影显示其强化程度最低。皮下肿块似乎不参与正常静脉循环。由于1岁3个月时肿块增大,遂对皮下肿块进行了手术切除。在将皮下肿块从头皮分离时,手动压迫主要静脉连接,很容易检测到次要静脉连接。术中出血可控。病理诊断为颅骨膜窦。患者现门诊随访。术后18个月未见复发。
讨论/结论:在将颅骨膜窦从颅骨分离时,术中止血至关重要。骨蜡或可吸收明胶等止血剂以及热凝固似乎很有用。然而,也有关于先前技术导致并发症性出血的报道。如我们的病例所示,为了检测颅骨膜窦与颅内静脉之间的微小分流点,手动压迫主要静脉连接。术中手动压迫颅骨膜窦的主要静脉连接可以作为处理术中出血的一种选择。
