Separation and reconstruction of the shared venous sinuses of craniopagus twins / 中华显微外科杂志

ABSTRACT

Objective To explore the importance of the separation and reconstruction of the shared venous sinuses of a craniopagus twins Methods The shared superior sagittal sinus, confluence of sinuses, transverse sinus and straight sinus were separated using microsurgical techniques Meantime, one bypass was established from the superior sagittal sinus and the straight sinus to the internal jugular vein with help of the bypass shunt in twin B (right) The above mentioned sinuses were reconstructed with the artificial vessels The normal superior sagittal sinus and confluence of sinuses were preserved in the twin A (left) Results Twin A recovered with no nervous deficits Unfortunately, twin B died of renal failure and hyperkalemia 22 hours after the operation Conclusion The shunt and reconstruction of the venous sinus are the key techniques for the success of separation of craniopagus twins using the microsurgical techniques
