Objective To assess the clinical value of pre-operative embolization for nasopharyngeal angiofibroma. Methods 13 patients with nasopharyngeal angiofibroma confirmed by surgery and biopsy were retrospectively analysed. Bilateral carotid artery angiograpy was perfomed for demonstration of the arterial supply of tumor. According to the size and different caliber of arteries, embolization were seperately undertaken by different types of coil via 4.1or 5F Head-Hunter catheter. The embolization efficacy, embolization was evaluated by amount of blood loss. Results After coil embolization , no complication happened ranging 1~4 days (mean 2 days) in all 13 patients and then all the tumor masses were totally resected with mean blood loss of (584.6?379.4) ml (range 250~1500 ml). Conclusions Preoperative coils embolization is safe, reliable with less complication especially for reducing intraoperative blood loss and promoting the prognosis.

0.05). The most frequent side-effects were abdominal pain and fever. The degree and duration of abdominal pain were higher and longer in group B than those in group A, but the occurrance rate of fever was lower in group B. The occurrance rate of severe complications showed no significant differences for both groups. The increase of embolization degree may aggravate post-embolization side-effects and raise the incidence of complications. Conclusions PVA may be used as the embolic material of PSE with embolization degree ranging from 50% to 70% which may alleviate hypersplenism in patients with cirrhosis, relieve post-embolization syndrome and decrease the incidence of severe complications.

Objective To study the therapeutic effect, side-effect and safety of uterine artery embolization of hysteromyoma with pinyangmycin and lipiodol emulsion. Methods Embolization carried out selectively through uterine artery with pinyangmycin and lipiodol emulsion of 158 hysteromyoma was followed up for 3-18 months with observation of the size of hysteromyoma, the change of corpus uteri and the degree of reactions. Results All cases were embolized successfully including 150 cases of bilateral and 8 cases of unilateral uterine arterial embolization. The appearance of uterine arteries showed obvious arterial enlargement with spiral hypervasculature, tumor staining and prolonged opacification. Six patients underwent hysteroectomy 1 week after the embolization. The specimens demonstrated flaky necrosis with small bloody specks under pathologic examination. The alleviation rate of symptoms were 90.5% with recovery of normal menstrual cycle as 89.4%. The compressive symptoms of hypogastric pain and abdominal distention disasppeared in 91.3%. The reduction in size of hysteromyoma and corpus utei were 80% and 48% on average respectively. Conclusion The primary results demonstrates that uterine artery embolization of hysteromyoma is safe and effective, with low complication rate and more advantage over surgical approach.

Objective To investigate the prognosis and prognostic risk factors of hepatic artery complications after orthotopic liver transplantation (OLT) treated with the interventional techniques.Methods The clinical data of 21 patients with hepatic artery complication after liver transplantation receiving thrombolysis, PTA, and stent placement in our institute from November 2003 to April 2007 were retrospectively analyzed. Based on the prognosis of grafts, 21 patients were divided into poor-prognosis group and non-poor-prognosis group. Fifteen variables (including biliary complication, hepatic artery restenosis,early or late artery complication, and so on) were analyzed in both groups with binary logistic regression analysis to screen out the risk factors related to prognosis of percutaneous interventional treatment for hepatic artery complications after OLT. Results Twenty-one patients were followed for mean 436 days, median 464 days (3-1037 days). The poor-prognosis group included 11 patients (5 cases received retransplantation, and 6 died). The mean survival time of grafts in poor-prognosis group was 191 days, and median survival time was 73 days (3-616 days). The mean survival time of grafts in non-poor-prognosis group which included 10 patients was 706 days, and median survival time was 692 days (245-1037 days).Univariate analysis showed there were significant difference in biliary complication, total bilirubin and indirect bilirubin between the two groups. The binary logistic regression analysis showed the risk factor related to prognosis was with biliary complication before the interventional management (P = 0.027, OR =22.818). Conclusion Biliary complication before interventional management is the risk factor related to poor prognosis of patients with hepatic artery stenosis or thrombisis receiving interventional treatment.

Objective To evaluate the therapeutic effect of transarterial chemoembolization (TACE) combined with CT-guided 125I seed implantation in treating hepatocellular carcinoma (HCC) complicated by portal vein tumor thrombus(PVTT), and to discuss the technical points. Methods A total of 48 HCC patients with PVTT were enrolled in this study. TACE combined with CT-guided 125I seed implantation was carried out in all 48 patients. Based on the sites of PVTT, the lesions were classified into type A (PVTT within main portal vein), type B(PVTT within level-1 portal branch) and type C(PVTT within level-2 or more distal portal branch). According to whether the 125I seeds were directly implanted into the PVTT or not, the patients were divided into direct in-tumor thrombus implantation group (group A) and around tumor thrombus implantation group (group B; the 125I seeds were implanted in the liver parenchyma or in tumor tissue around the tumor thrombus within 1.7 cm region). The tumor thrombus control rate(TTCR), the disease control rate(DCR), the time to progress(TTP) and the overall survival rate of patients(OS) were determined, and the results were compared among different types and groups. Results TACE combined with CT-guided 125I seed implantation was successfully accomplished in all 48 patients. The median OS of type A, B and C was 8, 11.5 and 15 months respectively(P=0.003);the TTCR of type A, B and C was 61.5%, 70.8%and 72.7%respectively(P=0.548); the DCR of type A, B and C was 69.2%, 75%and 81.8% respectively (P=0.483); the median TTP of type A, B and C was 4.5, 8 and 11 months respectively(P=0.030);the median TTP of intra-hepatic tumor of type A, B and C was 5, 9 and 9.5 months respectively(P=0.012). The median OS in group A and group B was 10 and 11.5 months respectively (P=0.239); the TTCR in group A and group B was 69.2% and 68.2%respectively(P=0.591); the DCR of intra-hepatic tumor in group A and group B was 73.1% and 77.3%respectively(P=0.502); the median TTP of tumor thrombus in group A and group B was 7 and 10 months respectively(P=0.276); and the median TTP of intra-hepatic tumor in group A and group B was 8 and 9.5 months respectively(P=0.089). Conclusion For the treatment of hepatocellular carcinoma complicated by portal vein tumor thrombus, TACE combined with CT-guided 125I seed implantation can effectively control the progress of both the tumor thrombus and the intra- hepatic tumor and prolong patient’s survival time. Implantation of 125I seeds into the portal vein tumor thrombus and implantation of 125I seeds into the liver parenchyma around the tumor thrombus have the same therapeutic results.
