Part VI of vascular intervention

See, the expansion of Ds vein thrombosis is a contraindication to liver transplantation. The results show that partial portal vein thrombosis for patients with liver cirrhosis, TIPSS is safe, can reduce or even completely disappear thrombosis. For liver transplantation for patients, TIPSS can avoid the increase of blood clots and reduce the risk of liver transplantation. Therefore, Ds venous thrombosis in patients with cirrhosis, TIPSS technique is the preferred method of treatment. 5. Percutaneous transluminal angioplasty Part VII of the key non-vascular interventional therapy, Pei Yi Gang, Fang Lei, Hu Road to the conference of non-vascular intervention to discuss the contents of multiple cells, more dispersed, this compilation category are described below. 1. Radio frequency (heat) ablation of the thyroid: The 236 patients in the treatment of 302 benign nodules, confirming ultrasound-guided radiofrequency ablation of benign thyroid nodules is a safe and effective. Liver Cancer: ① intraoperative radiofrequency ablation (radiofrequencyablation, RFA) percutaneous ablation therapy for hepatocellular carcinoma can not be implemented lesions. In the 6 years of 133 patients (220 lesions) to implement this treatment, 1 year and 5-year overall survival rates were 92.3 and 46.5, complication rate 6.8. Elevated serum alpha-fetoprotein after the treatment performance of poor prognosis. Can not be implemented for the percutaneous treatment of lesions, intraoperative RFA is safe and effective treatment can be used as secondary surgery. ② the left-Ye's line RFA treatment of hepatocellular carcinoma increases the risk of complications and retrospective comparison of the right lobe of the left lobe of RFA treatment of hepatocellular carcinoma tolerated. This group includes 5 years of radiofrequency treatment of hepatocellular carcinoma, 197 cases of consecutive patients,[link widoczny dla zalogowanych], including 38 cases of left lobe (47 lesions), right lobe of the 159 patients (198 lesions). Left lobe and right lobe of the occurrence of complications after radiofrequency ablation were l8 (7 / 38) and 49 / 6 (7 / 159) (P a 0.01). The multivariate analysis confirmed that the left lobe lesions,[link widoczny dla zalogowanych], multifocal hepatocellular carcinoma lesions under the capsule of patients, and can reduce the amount of iodized oil and help protect the remaining kidney function. Percutaneous transluminal angioplasty of the technical parameters,[link widoczny dla zalogowanych], including vessel size, choose the appropriate size of balloon, distending pressure, inflated the number of duration and expansion of application of anticoagulant drugs. Prospective study to assess the arteriovenous fistula after percutaneous transluminal angioplasty balloon time role. 180S balloon prolonged dialysis can significantly improve angioplasty success rate through the stenosis, this technique does not increase health care costs in the case of angioplasty techniques can improve the success rate. Assessment of hepatic artery stenosis after liver transplantation impact on the artery open and to assess the hepatic artery percutaneous transluminal angioplasty (with stent or no stent) to artery patency and graft survival rate. After liver transplantation in patients with hepatic artery stenosis often develop the risk of hepatic artery thrombosis, the use of endovascular techniques for the early treatment can significantly improve arterial patency, but it had no effect on graft survival. (Author: Huazhong University of Science Tongji Hospital, Tongji Medical College of Radiology) (From complication rate of risk factors. Left lobe after RFA of hepatocellular carcinoma is a risk factor for complications. Renal cell carcinoma: ① CT after RFA of renal tumors showed signs of fat within the urinary tract. This study attempts to find the incidence of urinary fat, time of onset and clinical performance. 145 cases of patients over one year follow-up after radiofrequency treatment of fat occurred in urine was 21 (31/145), the treatment of urinary fat after an average period of 1 year (3 years 1 month), 93 occurred in 6 cases months later. Is independent of and clinical performance. ② percutaneous treatment of renal tumors after RFA of renal halo sign (Renalhalosign) the incidence and clinical manifestations. Halo sign of renal imaging findings of the thin edge of the soft tissue around the center of the RF treatment. By enhanced CT or MRI evaluation after 10 years, 101 radiofrequency ablation of renal tumors, 56% (57/lO1) appeared halo sign, seen as early as 6 weeks after RF treatment,[link widoczny dla zalogowanych], no later than 3 years after treatment for RF. This can reduce symptoms but will not disappear. Recognizing the importance of this levy is that it is often not familiar with radio frequency ablation radiologists mistaken for angiomyolipoma. ③ contralateral renal insufficiency or renal cancer has been surgery, many elderly patients with partial or complete required dialysis after nephrectomy. For these patients with renal RFA has become an increasingly widely used treatment. The results show that some or the kidney
