Pseudoaneurysm of the ascending aorta after cardiac surgery is a rare but life threatening complication, which can result in rupture. Pseudoaneurysms are usually related to the aortic cannulation, the proximal site of graft anastomosis, or the suture line of aortotomy, and often occur after mediastinal infection. We report a case of pseudoaneurysm of the ascending aorta associated with aortic c...

BACKGROUND The role of portal vein embolization to increase future liver remnant (FLR) is well-established in the treatment of colorectal liver metastases. However, the role of hepatic vein embolization is unclear. CASE REPORT A patient with colorectal liver metastases received neoadjuvant chemotherapy prior to attempted resection. At the time of resection his tumor appeared to invade the lef...

BACKGROUND Factor V Leiden has been reported in 2%-30% of patients with portal vein thrombosis. This wide variation makes it difficult to assess the importance of factor V Leiden as a predisposing factor. METHODS Factor V Leiden was determined by restriction fragment length polymorphism in 112 patients with portal vein thrombosis, 104 with deep vein thrombosis and 98 control subjects. RESUL...

Biliary obstruction often follows advanced cancers of the biliary system, such as pancreas cancer, which requires a resection of the involved portion of the portal vein. To improve the patient's state of obstructive jaundice, bile drainage should be performed before the operation. Temporaryocclusion of the portal vein is inevitable for a resection and reconstruction of the portal vein, and its ...

Deep vein thrombosis is a common condition thought to be caused by impaired venous blood flow or hypercoagulable blood states. However, often no predisposing cause can be found. We describe a deep vein thrombosis formed in association with femoral osteochondroma and popliteal artery pseudoaneurysm. It is an interesting combination that has only been described once before.

AIM To evaluate the palliative therapeutic effects of transjugular intrahepatic portosystemic shunt (TIPS) in portal vein tumor thrombosis (PVTT) complicated by portal hypertension. METHODS We performed TIPS for 14 patients with PVTT due to hepatocellular carcinoma (HCC). Of the 14 patients, 8 patients had complete occlusion of the main portal vein, 6 patients had incomplete thrombosis, and 5...

Traumatic false aneurysm of the femoral vein has never been reported in the English literature. The case is here reported of a footballer with a traumatic false aneurysm of the common femoral vein which was initially misdiagnosed as an arterial pseudoaneurysm. This is a very rare clinical condition, but this diagnosis should be among those considered for post-traumatic unexplained thigh pain af...

Endoscopic ultrasound (EUS) offers access to many intra-abdominal vessels that until now have only been accessible to the surgeon and interventional radiologist. In addition to assisting with diagnostics, this unique access offers the potential for therapeutic intervention for a host of indications. To date, this has had the most clinical impact in the treatment of gastroesophageal varices, wit...

We have previously shown that intrasplenic fluid extravasation is important in controlling blood volume. We proposed that, because the splenic vein flows in the portal vein, portal hypertension would increase splenic venous pressure and thus increase intrasplenic microvascular pressure and fluid extravasation. Given that the rat spleen has no capacity to store/release blood, intrasplenic fluid ...

UNLABELLED Current recommendations for early anticoagulation in acute portal vein thrombosis unrelated to cirrhosis or malignancy are based on limited evidence. The aim of this study was to prospectively assess the risk factors, outcome, and prognosis in patients managed according to these recommendations. We enrolled 102 patients with acute thrombosis of the portal vein, or its left or right b...
