Seat line method of pineal region tumor

Hydrocephalus, such as tight adhesion between tumor and surrounding structures, can not all be cut,[link widoczny dla zalogowanych], or not sure aqueduct has been smooth, free of the silicone tube diameter of 2.0mm line the third ventricle of a cistern diversion to relieve obstructive hydrocephalus. The group 2 patients 1 month after review in CT,[link widoczny dla zalogowanych], showed obstructive hydrocephalus, consider the long-term suppression of tumor and postoperative adhesions induced ventricular aqueduct system infection, a shunt line effect of intracerebroventricular good. 4. Common complications and their treatment (1) air embolism: a seat by the tentorium, the cerebral approach on the removal of the serious complications of pineal region tumors], store location sitting head than the heart surgery or in combination mean intrathoracic chamber pressure decreases, blood volume reduction, central venous pressure decreased, the heart increases above the level of negative venous pressure, increased the incidence of air embolism can be difficult to damage some of the hard contraction or closure of the vein, as well as air into the blood vessels caused by . Its incidence has been reported as high as 25, but there was no reported air embolism]. Gas tied to those in the early surgery is about 73. There was no way to prevent a case before the craniotomy placed a tourniquet on the neck, such as intraoperative end-tidal concentration of CO show down, or a large vein bleeding, it can tighten the tourniquet, the intracranial venous pressure and to avoid the gas into the venous air embolism occurs Erzhi. However, if tied to large amount of gas or air embolism occurs rapidly, this method is difficult to work. Another catheter may be placed to monitor the pulmonary artery exclusion Huixin gas pressure and reduce complications, but the operation is more complex. The basic method of prevention is to avoid intraoperative rupture of a large vein or venous sinus to reduce bleeding. (2) cranial tension pneumocephalus: Since sitting gravity drainage of cerebrospinal fluid during surgery and ventricular drainage and other diuretic, making the brain collapse and subdural expansion of air into the subdural or intraventricular, intracranial, or the formation of gas, said tension down bottle effect dual-head CT examination common temporal subdural or double brow product gas, then you can set ventricle or continuous drainage of the subdural drainage, changing the head position of patients can be excluded from most of the gas, reducing gas cranial reaction, reduce intracranial pressure . This group of patients had postoperative air Lufa Sheng, only 2 cases of tension pneumocephalus cranial form, line after ventricular puncture and drainage tube placement, symptoms improved. (3) epidural hematoma: The group of 4 patients within 2 days headache, vomiting, CT examination revealed the top of the right temporal epidural hematoma, about 8oral. by surgery to remove the hematoma, the recovery was good. 5. by sitting Another major drawback is that the operation the surgeon fatigue, so the position of the patient placed in demanding operating table to avoid the surgery to minimize the operational difficulties raising of hands. In addition to shorten the operation time as much as possible.
