目的探讨经TIPS途径门静脉属支置管造影观察肝硬化门静脉高压失代偿期(DCPH)门体静脉间侧支血管(PSCV)的可行性及其造影表现。方法回顾性分析经临床确诊为DCPH并接受TIPS治疗的274例患者的资料。术中均经TIPS途径置管至肠系膜上静脉和脾静脉,行门静脉DSA造影。基于造影表现,对PSCV进行分类,并描述其特点。结果对274例患者均成功完成TIPS治疗及门静脉属支造影,根据PSCV在门静脉系统的起源部位,可将其分为4种类型:①门静脉分支型,占2.55%(7/274),为向肝血流且以分流为主;②门静脉主干型,占23.36%(64/274),为离肝血流且血流量较大;③门静脉属支型,占12.77%(35/274),为离肝血流且汇入体循环的途径较多;④混合型,占61.31%(168/274),为门静脉系多起源参与PSCV供血。结论经TIPS途径对DCPH患者进行门静脉属支置管DSA造影安全、可行,可显示PSCV的起源及其分型。各型PSCV具有不同的血流动力学特点。  相似文献

目的观察TACE联合小剂量阿帕替尼治疗肝细胞癌(HCC)合并门静脉癌栓的价值。方法将90例不可手术切除的原发性HCC合并门静脉癌栓患者随机分为治疗组及对照组,其中治疗组38例于TACE治疗后第3天开始口服小剂量(每日250 mg)阿帕替尼;对照组52例接受单纯TACE治疗。术后随访,比较2组间治疗前后甲胎蛋白水平及生存期的差异,分析2组患者的治疗有效率及术后不良反应情况。结果 2组患者TACE治疗的技术成功率均为100%。2组间治疗前甲胎蛋白水平差异无统计学意义(t=20.15,P=0.08),治疗组术后1、3、6、12个月甲胎蛋白水平均较对照组明显下降(P均0.05)。治疗组术后1、3、6、12、24个月肿瘤治疗有效率分别为89.47%(34/38)、84.21%(32/38)、78.95%(30/38)、34.21%(13/38)和10.53%(4/38);对照组分别为75.00%(39/52)、67.31%(35/52)、25.00%(13/52)、3.85%(2/52)和19.23%(10/52)。治疗组患者术后平均生存期明显长于对照组[(17.12±1.55)个月vs (14.21±2.13)个月,P=0.01]。虽然治疗组术后不良反应手足综合征、皮疹、腹泻、腹痛、消化道出血、蛋白尿、血尿、肌酐及尿素氮升高、眩晕、头痛、高血压、红细胞减少、白细胞减少、血红蛋白水平减低、血小板减少、转氨酶升高、胆红素升高的发生率均明显高于对照组(P均0.01),但其中美国国家癌症研究所(NCI)癌症常见毒性反应事件评价标准3级以上者较少。结论 TACE联合小剂量阿帕替尼治疗HCC在控制肿瘤及其合并癌栓进展方面优于单纯TACE,可有效延长患者生存期。  相似文献

Purpose

To compare segmental radioembolization with segmental chemoembolization for localized, unresectable hepatocellular carcinoma (HCC) not amenable to ablation.

Materials and Methods

In a single-center, retrospective study (2010–2015), 101 patients with 132 tumors underwent segmental radioembolization, and 77 patients with 103 tumors underwent segmental doxorubicin-based drug-eluting embolic or conventional chemoembolization. Patients receiving chemoembolization had worse performance status (Eastern Cooperative Oncology Group 0, 76% vs 56%; P = .003) and Child-Pugh class (class A, 65% vs 52%; P = .053); patients receiving radioembolization had larger tumors (32 mm vs 26 mm; P < .001), more infiltrative tumors (23% vs 9%; P = .01), and more vascular invasion (18% vs 1%; P < .001). Toxicity, tumor response, tumor progression, and survival were compared. Analyses were weighted using a propensity score (PS).

Results

Toxicity rates were low, without significant differences. Index and overall complete response rates were 92% and 84% for radioembolization and 74% and 58% for chemoembolization (P = .001 and P < .001). Index tumor progression at 1 and 2 years was 8% and 15% in the radioembolization group and 30% and 42% in the chemoembolization group (P < .001). Median progression-free and overall survival were 564 days and 1,198 days in the radioembolization group and 271 days and 1,043 days in the chemoembolization group (PS-adjusted P = .002 and P = .35; censored by transplant PS-adjusted P < .001 and P = .064).

Conclusions

Segmental radioembolization demonstrates higher complete response rates and local tumor control compared with segmental chemoembolization for HCC, with similar toxicity profiles. Superior progression-free survival was achieved.  相似文献

Purpose

To assess frequency of adverse events, efficacy, and clinical outcomes of percutaneous portal vein embolization (PVE) in patients with bilobar colorectal liver metastases undergoing staged hepatectomy with preservation of segment IV ± I only.

Materials and Methods

Retrospective analysis was performed of 40 consecutive patients who underwent right PVE after successful left lobectomy between 2005 and 2013. Rates of adverse events, future liver remnant (FLR) > 30% compared with baseline liver volume, clinical success (completion of staged hepatectomy with clearance of liver metastases), and overall survival were analyzed.

Results

PVE was performed using polyvinyl alcohol particles (n = 7; 17.5%), particles plus coils (n = 23; 57.5%), and N-butyl cyanoacrylate glue plus ethiodized oil (n = 10; 25%). Technical success was 100%. After PVE, 20% (n = 8) of patients exhibited portal venous thrombosis, ranging from isolated intrahepatic portal branch thrombosis to massive thrombosis of the main portal vein (n = 3) and responsible for periportal cavernoma and portal hypertension in 5 patients. Of patients, 23 (57.5%) had FLR ≥ 30%, and 21 (52.5%) had clinical success. Six patients had significant stenosis or occlusion of the left portal vein or biliary system after original left lobectomy, which was independently associated with FLR < 30% (R2 = 0.24). Clinical success was the only independent variable associated with survival (R2 = 0.25).

Conclusions

PVE for staged hepatectomy with preservation of segment IV ± I only is technically feasible, leading to adequate hypertrophy and clinical success rates in these patients with poor oncologic prognosis. Portal venous thrombosis is greater after the procedure than in the setting of standard PVE.  相似文献

Purpose

To test the hypothesis that a modified approach to portal vein embolization (PVE)—termed ablative liver partition (ALP) and PVE (ALP-PVE)—is feasible and results in greater future liver remnant (FLR) growth compared with PVE alone in a rabbit model.

Materials and Methods

Eighteen rabbits (median weight, 2.7 kg) underwent PVE (n = 9) or ALP-PVE (n = 9). PVE to cranial liver lobes was performed with 100–300-μm microspheres and metallic coils; the caudal lobe was spared as the FLR. In the ALP-PVE cohort, a liver partition between cranial and caudal lobes was created by using microwave ablation (40 W, 1 min). Animals were euthanized and livers were harvested on postprocedure day 7. Caudal and cranial liver lobes were weighed after 4 weeks of oven drying. Ki-67 immunohistochemistry was used to quantify liver mitotic index. ALP-PVE feasibility was determined based on procedure technical success. Standardized FLR (sFLR; ie, FLR divided by whole liver weight) and mitotic index were compared between PVE and ALP-PVE groups by two-tailed independent-samples Mann–Whitney U test.

Results

One PVE-group rabbit died during anesthesia induction and was excluded from technical success calculation. Eight of 8 (100%) and 8 of 9 rabbits (89%) underwent technically successful PVE and ALP-PVE, respectively. There was no difference in sex or weight distribution between groups. sFLR (0.32 vs 0.29; P = .022) and mitotic index (17.5% vs 6.2%; P = .051) were higher in ALP-PVE vs PVE caudal lobes when the first “learning-curve” case from each group was excluded.

Conclusions

ALP-PVE is feasible and may stimulate greater FLR growth compared with PVE in a rabbit model.  相似文献
