血管介入在肝硬化脾功能亢进中的应用研究进展

肝硬化是引起继发性脾功能亢进的常见原因,脾功能亢进常常导致患者外周血细胞降低,当白细胞和血小板严重减少时,患者易发生自发性感染和出血,进而加重病情,增加死亡风险.目前对肝硬化脾功能亢进发生机制尚不十分清楚,亦无脾亢治疗适应症标准和合适推荐方法,临床上脾亢的治疗方式有:脾切除术,血管介入术,局部热消融及脾动脉结扎术等.血管介入术主要涉及经颈静脉肝内门体分流术(transjugular intrahepatic portosystemic shunt,TIPS)和部分脾动脉栓塞术(partial splenic embolization,PSE),其中TIPS是治疗肝硬化门脉高压并发症的有效方法,它能有效降低门脉压力,但能否缓解脾亢仍存在争议;PSE对脾亢有一定程度的缓解;TIPS联合PSE应用,在有效降低门脉高压同时对脾亢也能一定程度缓解.本文就血管介入在肝硬化脾亢应用研究进展进行综述.     

Complications of Partial Splenic Embolization in Cirrhotic Patients

In recent years, partial splenic embolization (PSE) has been widely used in patients with cirrhosis and hypersplenism caused by portal hypertension. We investigated the complications associated with PSE cases seen in our hospital. Seventeen cases of liver cirrhosis that had undergone PSE were examined to investigate the complications associated with it. Mean infarcted area of the spleen was 66.2%. Leukocyte and platelet counts in 16 of 17 patients were seen to improve after PSE and persisted for at least one year. The most frequent side effects were abdominal pain (82.4%) and fever (94.1%). Severe side effects were seen in two of those 17 patients. One patient died from acute on chronic liver failure. The other patients contracted bacterial peritonitis and splenic abscess and needed drainage of splenic abscess before recovery. These two cases were in Child-Pugh class B. In conclusions, PSE is a useful treatment for patients with cirrhosis and hypersplenism caused by portal hypertension. However, the possibility of severe complications, especially in patients with noncompensated cirrhosis, should be kept in mind.

Partial splenic embolization as pretreatment for antiviral therapy in hepatitis C virus infection

Chronic hepatitis C virus infection is frequently complicated by cirrhosis and hypersplenism, which together with several other factors, such as reduced thrombopoietin synthesis in the liver, cause cytopenia. The antiviral combination therapy with pegylated interferon and ribavirin itself is impaired by haematological toxicity. Partial splenic embolization (PSE) by the injection of microspheres via a catheter comprising approximately 30-70% of the splenic parenchyma is now a safe method, which significantly reduces the cytopenia induced by hypersplenism, especially thrombocytopenia. The effect is long lasting up to 20 years and has been documented in a variety of disorders. PSE is now carefully described in a combination modality as a pretreatment to reduce cytopenia in hepatitis C virus-induced cirrhosis patients with hypersplenism, making antiviral therapy possible per se at higher dosages with a sustained duration.     

Partial splenic embolization in patients with liver cirrhosis and hepatocellular carcinoma: Effects on portal hemodynamics

Partial splenic embolization (PSE) was performed on patients with liver cirrhosis to control hypersplenism and gastroesophageal varices. In this study, we evaluated the effects of PSE on the portal hemodynamics and hepatic function of 17 cirrhotic patients with hepatocellular carcinoma. The mean splenic volume and the peak platelet count increased significantly and the splenic vein pressure decreased significantly after PSE. However, the portal blood flow did not change. Changes in the 15-min retention rate of indocyanine green and the arterial ketone body ratio were not significant, but the redox tolerance index increased from 0.24 ± 0.28 × 10^?2 to 0.59 ± 0.35 × 10^?2. These results suggest that PSE may reduce perioperative risks in cirrhotic patients with hepatocellular carcinoma who are candidates for hepatic resection.

Partial splenic embolization.

Partial splenic embolization (PSE) is a non-surgical procedure developed to treat hypersplenism as a result of hepatic disease and thus avoid the disadvantages of splenectomy. A femoral artery approach is used for selective catheterization of the splenic artery. Generally, the catheter tip is placed as distally as possible in an intrasplenic artery. After an injection of antibiotics and steroids, embolization is achieved by injecting 2-mm gelatin sponge cubes suspended in a saline solution containing antibiotics. PSE can benefit patients with thrombocytopenia, esophagogastric varices, portal hypertensive gastropathy, encephalopathy, liver dysfunction, splenic aneurysm, and splenic trauma. The contraindications of PSE include secondary splenomegaly and hypersplenism in patients with terminal-stage underlying disease; pyrexia or severe infections are associated with a high risk of splenic abscess after PSE. Complications of PSE include daily intermittent fever, abdominal pain, nausea and vomiting, abdominal fullness, appetite loss, and postembolization syndrome. Decreased portal-vein flow and a rapid increase in the platelet count after excessive embolization may cause portal-vein or splenic-vein thrombosis.

Short-term portal hemodynamic effects of partial splenic embolization for hypersplenism

BACKGROUND/AIMS: The purpose of this study was to investigate the short-term effects of partial splenic embolization (PSE) for hypersplenism on portal hemodynamics and liver function. METHODOLOGY: Thirty-seven patients with hypersplenism were included in this study. RESULTS: The wedged hepatic venous pressure before and after PSE were 39 +/- 10 and 33 +/- 8 cmH2O, respectively, showing significant change (p < 0.01). The flow volumes of the splenic vein before and after PSE were 477 +/- 200 and 319 +/-187 mL/min, respectively, also showing significant change (p < 0.05). However, the flow volumes of the portal vein before and after PSE were 713 +/- 284 and 684 +/- 152 mL/min, respectively, showing no significant change. The blood laboratory parameters showed no significant change after PSE. PSE damaged neither the portal blood flow volume nor the liver function, although it improved the local hyperdynamic state in the splenic area and thrombocytopenia. CONCLUSIONS: In conclusion, PSE is a safe and effective treatment for hypersplenism from the portal hemodynamic point of view.

Comparison of total splenic artery embolization and partial splenic embolization for hypersplenism

AIM: To evaluate whether total splenic artery embolization (TSAE) for patients with hypersplenism delivers better long-term outcomes than partial splenic embolization (PSE).METHODS: Sixty-one patients with hypersplenism eligible for TSAE (n = 27, group A) or PSE (n = 34, group B) were enrolled into the trial, which included clinical and computed tomography follow-up. Data on technical success, length of hospital stay, white blood cell (WBC) and platelet (PLT) counts, splenic volume and complications were collected at 2 wk, 6 mo, and 1, 2, 3, 4 years postoperatively.RESULTS: Both TSAE and PSE were technically successful in all patients. Complications were significantly fewer (P = 0.001), and hospital stay significantly shorter (P = 0.007), in group A than in group B. Post-procedure WBC and PLT counts in group A were significantly higher than those in group B from 6 mo to 4 years (P = 0.001), and post-procedure residual splenic volume in group A was significantly less than that observed in group B at 1, 2, 3 and 4 years post-procedure (P = 0.001). No significant differences were observed in red blood cell counts and liver function parameters between the two groups following the procedure.CONCLUSION: Our results indicate that TSAE for patients with hypersplenism not only delivers a better long-term outcome, but is also associated with lower complication rates and a shorter hospital stay than PSE.

Short-term Effects of Hepatic Arterial Buffer Responses Induced by Partial Splenic Embolization on the Hepatic Function of Patients with Cirrhosis According to the Child-Pugh Classification

Objective This study primarily aimed to investigate the short-term effects of partial splenic embolization (PSE) on the Child-Pugh score and identify predictive factors for changes in the score caused by PSE. The secondary aim was to analyze changes in various parameters at one month postoperatively using these identified factors. Methods Between September 2007 and December 2019, 118 patients with cirrhosis and hypersplenism underwent PSE at our hospital. Testing was conducted preoperatively and at one month after PSE. Results Overall, the Child-Pugh score was not significantly changed postoperatively. The Child-Pugh score before PSE was identified as the strongest independent predictor of ameliorated and deteriorated Child-Pugh scores after PSE. Higher pretreatment Child-Pugh scores were correlated with higher posttreatment amelioration rates of the score. A significant decrease in the portal vein diameter and a significant increase in the common hepatic artery diameter were evident at the same level postoperatively in 64 patients with Child-Pugh class A (group A) and in 54 patients with Child-Pugh class B or C (group B/C) preoperatively. According to Murray''s Law, PSE resulted in decreased portal venous flow and increased hepatic arterial flow, suggesting a hepatic arterial buffer response (HABR) induced by the procedure. Despite equivalent splenic infarction rates and similar posttreatment changes in hepatic hemodynamics, PSE significantly increased the Child-Pugh score of group A; however, the procedure significantly decreased the score of group B/C. Conclusion Considering original portal venous-hepatic arterial hemodynamics, PSE is expected to produce HABR-mediated hepatic functional improvements in cirrhosis patients with Child-Pugh class B/C.
