Abdominal Fullness

Extrahepatic portal vein aneurysm is a rare disorder. From 1956 to 2008, we found only 43 published English-language reports, including 67 cases, using Pub Med. We report a case of a 77-year-old woman who had complaints of lower abdominal fullness and residual urine. We performed ultrasonography (US), which demonstrated a congenital extrahepatic portal vein aneurysm. She had no obvious symptoms of the extrahepatic portal vein aneurysm. She had undergone gastrectomy without blood transfusion for gastric ulcer more than 20 years ago. Physical examination revealed no abnormal findings. US revealed a2.2×1.8 cm, round shaped hypoechogenic lesion at the hepatic hilum. Color Doppler US showed bidirectional colors due to circular flow within this lesion. 3D-CT and CT angiography demonstrated that the saccular aneurysm at the hepatic hilum was 3.0 cm in diameter and was enhanced equal to that of portal vein.Twenty-six months after the diagnosis, the aneurysm had not grown in size. Since our patient had no serious complaints or liver disease, surgical procedures had not been employed. US and 3D-CT are noninvasive diagnostic techniques and are helpful in the diagnosis and follow-up of extrahepatic portal vein aneurysms.

Portal Vein Aneurysm

A case of a 70 year old man who was found to have an extrahepatic portal vein aneurysm during an evaluation for hematuria is reported. Extrahepatic portal vein aneurysms are rare with only twenty cases reported in the literature. Typically, patients present with hemorrhage requiring surgical exploration or the aneurysm is discovered during evaluation of another abdominal process. Management includes careful follow-up in the asymptomatic patient without underlying liver disease or portal hypertension.

Background Portal vein aneurysms are rare dilations in the portal venous system, for which the etiology and pathophysiological consequences are poorly understood. Method We reviewed the existing literature as well as present a unique anecdotal case of a patient presenting with a very large portal vein aneurysm that was successfully managed conservatively and non-operatively without anticoagulation, with close follow-up and routine surveillance. Result The rising prevalence of abdominal imaging in clinical practice has increased rates of portal vein aneurysm detection. While asymptomatic aneurysms less than 3 cm can be clinically observed, surgical intervention may be necessary in large asymptomatic aneurysms (>3 cm) with or without thrombus, or small aneurysms with evidence of evolving mural thrombus formation on imaging. Conclusion Portal vein aneurysms present a diagnostic challenge for any surgeon, and the goal for surgical therapy is based on repairing the portal vein aneurysm, and if portal hypertension is present decompressing via surgically constructed shunts.

Uncertain Etiology

Portal vein aneurysm (PVA) is a rare vascular entity of uncertain etiology. Saccular PVA is the less frequently reported morphology but often with more symptoms or complications. Ultrasound, along with color doppler study, is a valuable tool in the diagnosis and follow-up.

Inflammatory Changes

We introduce a case of a 73-year-old man who developed intractable chylous ascites due to portal vein compression as a result of peripancreatic inflammatory changes after acute biliary pancreatitis. After stenting the portal vein stenosis, the chylous ascites improved from requiring weekly paracentesis to requiring no drainage within 4 months of the procedure and at the 15-month follow-up. To our knowledge, it is the first case reported in the literature where portal vein stenting has successfully been used to treat pancreatitis-induced chylous ascites.

Abstract Background Our purpose is to compare the stent patency and clinical outcome of trans-jugular intra-hepatic porto-systemic shunt (TIPS) through the left branch portal vein (TIPS-LPV) to the standard TIPS through the right branch (TIPS-RPV). We retrospectively reviewed all patients (n = 54) with refractory portal hypertension who were subjected to TIPS-LPV at our institute (TIPS-LPV) between 2016 and 2018. These patients were matched with 56 control patients treated with the standard TIPS-RPV (TIPS-RPV). The 2 groups were compared regarding the stent patency rate, encephalopathy, and re-interventions for 1 year after the procedure. Results TIPS-LPV group showed 12 months higher patency rate (90.7% compared to 73.2%) (P < 0.005). The number of the encephalopathy attacks in the TIPS-LPV group was significantly lower than that of the TIPS-RPV group at 6 and 12 months of follow-up [P = 0.012 and 0.036, respectively]. Re-bleeding and improvement of ascites were the same in the two groups [P > 0.05]. Patients underwent TIPS-LPV needed less re-interventions and required less hospitalizations than those with TIPS-RPV [P = 0.039 and P = 0.03, respectively]. Conclusion The new TIPS approach is to extend the stent to LPV. This new TIPS-LPV approach showed the same clinical efficiency as the standard TIPS-RPV in treating variceal bleeding and ascites. However, it proved a better stent patency with lower rates of re-interventions, encephalopathy, and hospital admissions than TIPS through the right branch.
