Objective To explore the appearances of DSA and therapeutic methods of tanscatheter hepatic artery chomoembolization (THACE) of hepatic carcinoma with arteriovenous fistula(avf).Methods The indirect hepatic portal vein angiography (Superior mesenteric artery angiography) and celiac trunk angiography (common hepatic artery) were performed in 673 cases with hepatic carcinoma confirmed by pathology,then hepatic artery infusion-chemotherapy and/or embolizations were done. Results Heptic carcinoma to be accompanied with arteriovenous fistula(AVF) 151 was totally cases(22.4%),including artery-portal vein fistula 127 cases,artery-vein fistula 15 cases, mixed 9 cases.Of them, hepatic artery embolizations in 131 cases with artery-vein fistula(86.6%) were performed once or more times, in 20 cases due to the embolization of artery-vein fistula couldn’t be performed and/or with tumor embolus inside common portal vein while only arterial infusion-chemotherapy were performed.Conclusion DSA is accurate and direct diagnostic method in hepatic carcinoma with artery-vein fistula. Hepatic artery embolization and infusion-chemotherapy is an effective way for the patients with artery-vein fistula.

Objective To explore the clinical application value of ultrasound-guided intrahepatic biliary puncture combined with internal double biliary stenting under DSA in elderly patients with malignant hilar biliary obstruction (MHBO).Methods Totally 108 elderly MHBO patients received interventional treatment were analyzed retrospectively.Half of patients were treated with ultrasound-guided intrahepatic biliary puncture (ultrasound group),and another 54 patients were treated with DSA intrahepatic biliary puncture (DSA group).After successful puncture,the patients received percutaneous transhepatic cholangial drainage (PTCD) with 4 methods under DSA guidance,namely internal double biliary stenting,contralateral external PTCD with single biliary stenting,complete external PTCD and external PTCD on the dominant side.The recent complications of intrahepatic biliary puncture at two groups and the curative effect with four methods were observed.Results The frequency of intrahepatic biliary puncture,the dosage of contrast agent,the incidence of pain at the puncture point and hemobilia in ultrasound group were all lower than those in DSA group (all P＜0.05),the successful rate of intrahepatic biliary puncture in first time was significantly higher compared with DSA group (P＜0.05).The liver function indicators at 14 days postoperation and total bilirubin at 21 days postoperation had statistical differences between any two biliary drainage methods (all P＜ 0.05).Conclusion Ultrasound-guide intrahepatic biliary puncture combined with internal double biliary stenting under DSA can significantly benefit elderly patients with MHBO.

Objective To evaluate the role of mesenchymal stem cells (MSCs) derived from mouse bone and embryo dorsal aorta(DA) area in the treatment of irradiation induced lung injury of mouse model. Methods The mice were divided into four groups as normal control group, irradiation group,bone MSCs treatment group and DA MSCs treatment group. Immunohistochemical Analysis of lung tissue was observed after 9 months of treatment. Results Fibrosis and alveolar infiltration were scored in each group. The score for fibrosis and alveolar is 0. 17 in normal control group, 2 in irradiation group, 1 in bone MSCs treat group and 1.38 in DA MSCs treat group. Conclusion The extent of irradiation Induced Lung Injury could be reduced thorough the treatment of MSCs derived from mouse bone and embryos dorsal aorta ( DA ) area.

Objective To investigate the causes of recurrent hemoptysis one week after interventional treatment.Methods 56 patients with massive hemoptysis were included in this study.All patients underwent emergent interventional therapy, including angiography and embolization therapy of bronchial artery, intercostal artery, internal thoracic artery, external thoracic artery and phrenic artery via femoral artery puncture.Results 6 cases had rebleeding within one week after interventional therapy,including 2 cases with primary lung cancer,1 case with bronchiectasis,1 case with pulmonary tuberculosis,1 case with esophageal cancer after surgery,1 case with esophageal cancer after radiotherapy.Then, these patients once again underwent angiography and embolization therapy of bronchial artery,intercostal artery,internal thoracic artery,external thoracic artery and phrenic artery.Conclusion The use of vasoconstrictive drugs before intervention, diversification of pulmonary feeding artery, wide range of lesions, inappropriate embolic material and poor image quality can lead to recurrent hemoptysis after interventional treatment.

Objective To probe the blood supply of liver metastasis by celiac artery,proper hepatic artery DSA.portal vein perfusion CT during superior mesenteric arterial poaography(PCTAP).Methods One hundred patients with liver metastases were examined prospectively by plain CT scan,multiphase enhanced CT scan,celiac arteriography and proper hepatic artefiography.Of them,56 patients were examined by PCTAP.All primary lesions wero confirmed by operation and(or)pathology examination.In order to investigate the blood supply of metastasis lesions.the software of Photoshop Was used to obtain the time-attenuation cugves(TDC)of tumor center,tumor edge,portal vein and normal liver parenchyma adjacent to the tumor to talculate liver perfusion for DSA image analysis,while a deconvolution model from CT perfusion software Was designed for the dual blood supply.Results DSA findings:TDC of proper hepatic arteriography showed:the mean peak concentration(K value)in tumor centers was(67±12)%,and it was(76±15)%for peritumor tissue,(51±10)%in normal liver parenchyma.TDC of celiac arteriogaphy showed that the contrast concentration of tumor centers and tumor edge increased fast in early stage.then maintained a slight upward plateau,in the meanwhile,the contrast concentration of normal liver parenchyma kept increasing slowly.PCTAP findings:tumors exhibited no enhancement during 30 s continued scans.Conciusion The blood supply of liver metastasis mainly comes from hepatic artery,but barely from portal vein.
