Abdominal venous thrombosis presenting in myeloproliferative neoplasm with JAK2 V617F mutation: a case report

The Significance of Serum CA-125 Elevation in Chinese Patients with Primary Budd-Chiari Syndrome: A Multicenter Study

Objective. To investigate the serum level of CA-125 and its corresponding clinical significance in Chinese patients with primary BCS. Methods. Serum CA-125 was measured in 243 patients with primary BCS receiving interventional treatment in the participating hospitals and in 120 healthy volunteers. The correlation between serum CA-125 levels and ascites volume, liver function, and prognosis was analyzed. Results. Serum CA-125 was significantly elevated in BCS patients compared to healthy volunteers (P < 0.001). Higher levels of CA-125 were found in BCS patients with abnormal hepatic function and low serum albumin levels and in patients with high volume of ascites compared to patients without these abnormalities. Serum CA-125 levels significantly correlated with ascites volume, serum level of alanine aminotransferase, aspartate aminotransferase, albumin, and Rotterdam BCS scores. The follow-up study indicated that the survival rate and asymptomatic survival rate after interventional treatment were lower in BCS patients with serum CA-125 > 175 U/mL (P < 0.05). Conclusion. Serum CA-125 was significantly higher in patients with primary BCS and had a positive correlation with the volume of ascites, severity of liver damage, and poor prognosis. Thus the serum CA-125 levels may be used to estimate the severity and prognosis of BCS in Chinese patients.

Initial imaging analysis of Budd-Chiari syndrome in Henan province of China: most cases have combined inferior vena cava and hepatic veins involvement

AIM

To evaluate the type of venous involvement in Chinese Budd-Chiari syndrome (BCS) patients and the relative diagnostic accuracy of the different imaging modalities.

METHODS

Using digital subtraction angiography (DSA) as a reference standard, color Doppler ultrasound (CDUS), computed tomography angiography (CTA), and magnetic resonance angiography (MRA) were performed on 338 patients with BCS. We analyzed the course of the main and any accessory hepatic veins (HVs) and the inferior vena cava (IVC) to assess the etiology of obstructed segments and diagnostic accuracy of CDUS, CTA and MRA.

RESULTS

Among the 338 cases, there were 8 cases (2.4%) of isolated IVC membranous obstruction, 45 cases (13.3%) of isolated HV occlusion, and 285 cases (84.3%) with both IVC membranous obstruction and HV occlusion. Comparing with DSA, CDUS, CTA had a diagnostic accuracy of 89.3% and 80.2% in detecting BCS, and 83.4% of cases correctly correlated by MRA.

CONCLUSION

In Henan Province, most patients with BCS have complex lesions combining IVC and HV involvement. The combination of CDUS and CTA or MRI is useful for diagnosis of BCS and guiding therapy.

Clinical features and etiology of Budd-Chiari syndrome in Chinese patients: a single-center study

BACKGROUND AND AIM

The clinical features and etiology of Budd-Chiari syndrome (BCS) vary from region to region, and there is lack of large sample studies about BCS in China. The aim of the present study was to study the clinical features and etiology of patients with incident BCS in China prospectively.

METHODS

A consecutive case series of patients with incident BCS who were diagnosed in the Affiliated Hospital of Xuzhou Medical College (Jiangsu, China) were enrolled from September 2010 to December 2011. All of the patients had continuous follow-ups to record the symptoms, body features, laboratory and radiology findings, and treatment methods through May 2012.

RESULTS

A total of 145 incident cases of BCS were identified. BCS was caused by hepatic venous obstruction in 31% of the patients, inferior vena cava obstruction in 6% of the patients, and 63% suffered from a combination of the two conditions. At least one etiological factor was present in 82% of the patients, with the most common being membranous obstruction (61%). Only 5% of the patients had myeloproliferative neoplasms with a JAK2 V617F mutation, and none of the patients had a factor V Leiden mutation. Eighteen months after a percutaneous transluminal angioplasty was performed, the survival rate and the asymptomatic survival rate were 99% (95% confidence interval, 95-100%) and 93% (95% confidence interval, 89-98%), respectively.

CONCLUSION

The most prevalent etiological factor for BCS in China is membranous obstruction. Moreover, most Chinese patients with chronic BCS are treated with percutaneous transluminal angioplasty and have an excellent clinical outcome.
