ABSTRACT
Objective To discuss the selection of diagnosis for intracranial aneutysms,and to analyze thera-peutic efficacy of microsurgical treatment and endovascular embolizafion in the treatment of intracranial aneurysms.Methods 190 pailents suffeming from intracranial aneurysms experienced brain CT examination.37 cases detected by MRI.31 cases detected by MRA,134 were confirmed by computered tomographic angiography(CTA)or 3D-CTA,and 142 cases were confirmed by digital subtract angiography(DSA).96 patients underwent microsurgical treatment,4 of whom failed in endovascular embolization.92 cases underwent endovascufar therapy,2 of whom were embolized by ONYX,and the other were embolized by guglielmi detachable coil(GDC).Results 9 patients died,2 of whorn died of re-hemorrhage,3 died of severe vasospasm,4 died of pneumonia and other complications,and the others were cured.Conclusion CT is the first choice for the subarachniod hemorrhage;MBA could be a choice for the detection of intracranial aneurysm without hemorrhage,but is not suit for the aneurysm clipping.The size-form,relationship with patent arteries,and even the raptured point of aneurysms can be clearly demonstrated by CTA-and CTA can be used to the operation for intracranial aneurysms directly.DSA-especially 3D-DSA Call display the blood supply of the complicated aneurysms clearly,and can guide the treatment for intracnmial aneurysms directly.Endo-vascular therapy and aneurysm clipping seem like complimentary than competitive,patients with acute cerebral edema should try to undergo endovascular therapy,while the patients with severe vasespasm should be treated with microsur-gical operation immediately and resolutely.The ruptured aneurysms in multiple intracraniul aneurysm should be iden-tified correctly and treated in the early stage.
ABSTRACT
Objective To study the causes, significance of alteration of PtiO 2, PtiCO 2 and pHti in liver tissue during liver ischemia reperfusion (I R). Methods After rabbits were anesthetized, liver ischemia was induced by complete occlusion of the hepatoduodenal ligment for 45 min, then the portal and arterial flow were released, and observed for 120 min for measuring the PtiO 2, PtiCO 2 and pHti in liver tissue and the pathology of the liver during ischemia reperfusion. Results After 15 min of hepatic vascular occlusion, PtiO 2 decreased to 4 mmHg, PtiCO 2 increased fast to (149.63?9.80) mmHg (P
ABSTRACT
Twenty- five patients with severe head injury underwent early total parenteral nutrtion (TPN) support,and the blood glucose,serum albumin,body nutritional index and nitrogen balance were monitored in our case- controll study.We find that the patients with severe head injury could get more energy and protein from TPN than from enteral nutrition (EN) ,the mortality of the patients with TPN was significantly lower than the patients with EN.The total nutrient admixture(TNA) in our study can provide sufficient energy and protein,but cannot raise blood glucose,so it can make a good condition for the recovery of the severe head injuries.
