RESUMO
PURPOSE: To evaluate liver function improvement and volume gain after percutaneous recanalization of chronic portal vein thrombosis (PVT) in non-cirrhotic patients. MATERIALS AND METHODS: In this retrospective study, five non-cirrhotic participants between 21 and 67 years old with secondary chronic PVT (4-21 years from diagnose) were submitted to percutaneous portal vein recanalization, followed by varices and shunts embolization. RESULTS: After a mean of 12.6 months, all portal veins remained patent and there was complete resolution of portal hypertension (PH) symptoms in all participants. There was a significant increase in liver volume of 39.8 ± 19.0% (p = 0.042), platelets count of 53120 ± 20188/µl (p = 0.042), and a significant decrease in total bilirubin levels from 1.04 ± 0.23 mg/dL to 0.51 ± 0.09 mg/dL (p = 0.043). We also found a non-significant increase in albumin levels from 3.88 ± 0.39 g/dL to 4.38 ± 0.27 g/dL (p = 0.078) and decrease in spleen diameter from 16.88 ± 4.03 cm to 14.15 ± 2.72 cm (p = 0.068). DISCUSSION: In this retrospective study, even with a small number of participants, we were capable of showing a median of 39.8% increase in liver volume, laboratorial liver function improvement, platelets count and resolution of PH symptoms, including gastroesophageal varices disappearance after portal vein recanalization followed by shunt embolization. CONCLUSION: In this small series of cases, recanalization of chronic PVT in non-cirrhotic participants was feasible, successful and safe despite the prolonged time of occlusion. This is a new and promising approaching to an old and still challenging disease.

INTRODUCTION: To evaluate the efficacy and clinical safety of bariatric arterial embolization (BAE) in adults with body mass index (BMI) between 30 and 39.9 kg/m2 and metabolic syndrome (MS). MATERIALS AND METHODS: Between March and August 2018, ten female participants between 21 and 48-years-old, median BMI of 36.37 ± 2.58 kg/m2 and MS were enrolled in this prospective trial. We embolized the fundal branches from the left gastric and other artery sources, which resulted in embolization of at least two arteries in 9 out 10 participants. Six months after bariatric embolization, efficacy was assessed by changes in total body weight (TBW), ghrelin and Homeostatic Model Assessment-Insulin Resistance (HOMA-IR) levels and by changes in quality of life (QOL) and in binge eating scale (BES) scores. Safety was assessed by the identification of any related complications, including gastric ulcers, screened by gastrointestinal endoscopy, performed before and one week and one month after BAE. RESULTS: Six months after embolization, TBW decreased by 6.8% (6.22 kg ± 3.6;p = .01), serum ghrelin dropped from 25.39 pg/ml ± 10.63 to 17.1 ± 8.07 (p = 0.01), and HOMA-IR decreased from 7.29 ± 5.66 to 3.73 ± 1.99 (p = 0.01). The QOL scores improved from 59.64 ± 5.59 to 69.02 ± 11.97 (p < 0.05) and in the BES from 21.50 ± 8.89 to 9.60 ± 4.40 (p = 0.01). Endoscopy revealed symptomatic gastric ulcers in two participants, which had healed without sequelae. In one participant, ultrasound revealed an asymptomatic focal arterial thrombus at the left distal radial artery puncture site. CONCLUSION: BAE is effective in reducing weight, insulin resistance and ghrelin levels and improving BES and QOL scores in patients with class I and II obesity and MS, with no major complications.
