3 cases of intracranial aneurismal residue following clipping at Viet Duc Hospital were studied. The causes of this condition were anatomical and technical. It is necessary to identified prior surgery the cause of hemorrhage, to limit the disruption of aneurism, to expose entirely the neck of aneurism before the setting of clip and to explore throughly the place of clip- Anterigraphy or systematic Xray control should be made for checking the results

This association had been reported for long time with a frequency of 2.7-23% of cases of intracerebral arteriovenous connection. This association increases the risk of cerebral meningo hemorrhage. 3 cases of cerebral meningo hemorrhage associated with intracerebral arteriovenous connective malformation were studied retrospectively and treated at Viet Duc Hospital from January 1999 to January 2004. The presence of aneurysm in cerebral arteriovenous connection was an important predictive factor for the hemorrhage possibility, leading to cerebral hemorrhage

Meningocerebral haemorrhage due to the rupture of malformation of cerebral arterio venous fistula is neurosurgical emegency that requires the radical management to prevent from relapsed haemorrhage. Currently in Vietnam, the operation for malformation removal is an unique technique. The restrespective study on 16 cases suffered the rupture of malformation of cerebral arterio venous fistula in Vietduc during 1999-2000 showed the encourage results. 81.3% of malformations were radically removed, 18.7% of malformation were partial removed and experienced ligation of artery the outcomes: good (81%) and no death

A retrospective study on 14 case of ruptured cerebral cranial carotid aneurysm operated in Viet Duc Hospital during 1998 - 2000 has shown that the clinical outcome and method of operation found well in 78.6% of patients. The time for operation was usually late (often 2-3 weeks of bleeding).

Objective To investigate the application of butterfly-like transparent dressing in tracheotomy.Methods 62 cases of patients treated with tracheotomy for acute respiratory failure were adopted in this study and divided into the observation group(32 cases)and the control group(30 cases).The observation group WaS covered with butterfly-like transparent dressing and the control group Was covered with common adhesive plaster.Noninvasive ventilation after withdrawal of endotracheal intubation calmula,tolerance,reaction of local skin and mean time of concrescence were observed.Results The observation group showed greater tolerance,lesser local adverse reaction and shorter mean time of concrescence than those of the control group.Conclu-sion Butterfly-like transparent dressingis a kind of good dressing for incision of trachcotomy.

Objective To explore the clinical features of tubal pregnancy and summarize the diagnosis and treatment.Methods The clinical data of 287 cases were reviewed including routine test,ultrasound examination,and laparoscopic surgery.The clinical features and indicators of surgery were evaluated,193 cases treated by laparoscopic surgery and 94 cases treated by traditional surgery.Results ( 1 ) The major clinical manifestations of tubal pregnancy were abdominal pain ( 100％ ),menopause ( 80.8％ ) and irregular vaginal bleeding (62.4％).(2) By ultrasound examination mass was found in 257 cases (89.5％ ),and pelvic cavity accumulates liquid in 167 cases (58.2％ ).In accessories division 32 cases ( 11.1％ ) had blastocyst and 19 cases (6.6％ ) had embryo or fetal heart.The positive rate of urine pregnancy test was 86.4％,and the average level of blood 3-HCG was (545.0 ± 231.6) U/L.( 3 ) The past medical history was as follows:Tirty-four cases ( 11.8％ ) with ligation or other method of contraception,43 cases ( 15.0％ ) with surgery,87 cases (30.3％ )with artiflcal abortion,and 33 cases ( 11.5％ ) with hepatitis,malaria or tuberculosis.(4)All the surgery succeed with an average surgery time of (44.5 ± 6.7 ) min.Ninety-seven cases were treated with blood transfusion and there were no complications.Operative wound of all patients were healed first term,and the time stay in hospital was (4.1 ± 2.7 ) d,and the levels of blood β-HCG all dropped ≥50％ by 24 h after surgery.Conclusion ( 1 ) Abdominal pain,menopause,and irregular vaginal bleeding are the major clinical manifestations of tubal pregnancy.(2)The best method of diagnosis in tubal pregnancy is blood β-HCG and ultrasound examination.(3) Laparoscopic gynaecological surgery has such merits as minimal invasion,and it is the best way for diagnosis and treatment of tubal pregnancy.

Hepatic echinococcosis(HE)is a zoonosis seriously affecting the population in west China.Computed tomography(CT),magnetic resonance angiography,ultrasound angiography can be used for detection of HE with the advantages of multiple angles and high definition.CT perfusion imaging,magnetic resonance perfusion imaging,diffusion weighted imaging and magnetic resonance spectrum may provide molecular imaging to visualize HE in vitro.Total cystectomy is a radical method for the treatment of hepatic cystic echinococcosis (HCE),but has the drawbacks of HE recurrence and bile leakage;subradical cystectomy not only eliminate residual cavity of HAE,but also effectively avoids the risks which might be caused by total cystectomy.Radical hepatectomy is the first choice for the treatment of hepatic alveolar echinococcosis(HAE),while for patients with end-stage HCE,liver transplantation is the final choice of treatment.

Though CT scan is the main diagnostic method of pancreatic diseases, it is less than satisfying in ear-ly diagnosis and differential diagnosis of pancreatic diseases. As a new technology, pancreatic CT perfusion imaging shows abnormal blood perfusion caused by local pathological changes, by mean of measuring parameters BF, BV, PS, etc. Used in imaging diagnosis, CT perfusion imaging can improve early diagnosis ability and raise the accuracy of differential diagnosis. Accordingly, the prospect of pancreatic CT perfusion imaging is promising.

Objective: To discuss the effect of bone marrow mobilization on chemotaxis of aggregation of macrophages in venous thrombosis. Methods:SD adult rats were divided randomly into normal group,sham operation group,thrombus group and rhG-CSF group.Peripheral blood was harvested at 30min before operation and on the 7th and 14th day after operation.Level of MCP-3 in peripheral blood was detected by ELISA.Inferior vena cava specimens of thromus group and rhG-CSF group were collected at postoperative 7th and 14th day. With the application of RT-PCR,expression of MCP-3mRNA in thrombus was detected.Results:The level of MCP-3 in peripheral blood of rhG-CSF group was significantly higher than that before operation and also higher than the levels of MCP-3 in peripheral blood of sham operation group and thrombus group on the 14th day after operation(P<0.05),and the difference was significant.On the 7th and 14th day after operation,compared with thrombus group,the expression of MCP-3 mRNA in rhG-CSF group remarkablely increased,and the difference Was significant beween these two groups(P<0.01).Conclusion:Brone marrow cell mobilization enhances the chemotaxis of MCP-3 on macrophages.
