Central venous catheterization via an internal jugular vein or subclavian vein has become a common procedure in monitoring CVP and managing severely ill patients. However, there have beennumerous reports of complications associated with central venous catheterization. These include vessel injury, pneumothorax, hemothorax, nerve injury, arrhythmias, arteriovenous thrombosis, pulmonary embolism, and infection at the insertion site. We report a case of hemothorax after subclavian vein catheterization failure, along with successful treatment.

We report a case of a 48-year-old woman with end-stage renal failure who had a Polytetrafluoroethylene graft for hemodialysis and who had developed complications of venous outflow stenosis and venous backflow. Although venous backflow is an harbinger of graft failure, it is not enough reason to abandon the graft immediately. The patient was able to utilize her graft for 6 further months.

The efficacy of injection sclerotherapy for treatment of acute esophageal variceal bleeding is well established. But several complications of endoscopic sclerotherapy have been reported. One of the complications is mesenteric venous thrombosis which develops when vasopressin is used for the sclerotherapy. We report a case of superior mesenteric venous thrombosis which developed after endoscopic sclerotherapy for control of esophageal variceal bleeding.

Tissue defect reconstruction using radial forearm free flap (RFFF) is a common surgical technique whose success or failure is mainly dependent on venous drainage. RFFF has two major venous outflow systems, superficial and deep vein. Drainage methods include combining both systems or using one alone. This review aims to recapitulate the vascular anatomy and network of RFFF as well as shed light on deep vein as a reliable venous drainage system. We also discuss basic evidence for and advantages of single microanastomosis with coalesced vein to overcome technical difficulties associated with the deep vein system.

The studies were conducted to ramify the splenic trabecular veins by injection of vinylite into the splenic veins in twenty five adult Korean cattle. The following results were obtained. 1. Splenic trabecular veins of bovine were collected from 3 chief Rami lienales: Rr. superior, inferior and V. polaris superior of the splenic veins, and the splenic parenchyma was ramified to 5-11 intralienal venous segments by the course of the trabecular veins. 2. Each one of the intralienal venous segments was dealt with 2-4 minute segments therefore, the splenic parenchyma was ramified from 13 minute segments in minimum to 35 minute segments in maximum. 3. The distribution of the veins in the spleen was divided into 7 types by the number of intralienal venous segment, and also was 15 kinds by collecting veins, Rr. superior et inferior and V. polaris superior. 4. The anastomosis was observed in the intralienal venous segments or minute segments. 5. Generally the splenic veins and arteries were like each other, but when observed minutely, they were unlike.

Dural ateriovenous fistula (DAVF) at the craniocervical junction is rare. We report a patient presenting with brainstem dysfunction as an uncommon onset. Brainstem lesion was suggested by magnetic resonance image study. Angiogram revealed a DAVF at a high cervical segment supplied by the meningeal branch of the right vertebral artery, with ascending and descending venous drainage. Complete obliteration of the fistula was achieved via transarterial Onyx embolization. Clinical cure was achieved in the follow-up period; meanwhile, imaging abnormalities of this case disappeared. Accordingly, we hypothesize that a brainstem lesion of this case was caused by craniocervical DAVF, which induced venous hypertension. Thus, venous drainage patterns should be paid attention to because they are important for diagnosis and theraputic strategy.

Central venous catheter (CVC) insertion is commonly used in the operating room and intensive care unit to monitor central venous pressure and secure an intravenous route to deliver medications and nutritional support that cannot be safely infused into peripheral veins. However, CVC insertion may be associated with serious complications such as arterial puncture, hematoma, pneumothorax, hemothorax, catheter infections, and thrombosis. Several methods have been recommended to prevent these complications. Here we report a case of massive hemothorax caused by attempts of CVC insertion into the internal jugular vein and subclavian vein in a patient with multiple trauma. CVC placement should be performed or supervised by an experienced physician to decrease the incidence of CVC-related complications. CVC insertion under ultrasound guidance is recommended.

Adventitial cystic disease of the vein is a rare vascular disease. Herein, we report a case of adventitial cystic disease of the common femoral vein that was initially misdiagnosed as deep venous thrombosis in a 41-year-old male who presented with leg swelling. We focused on the imaging findings and compared them with those of deep venous thrombosis.

Prognosis of patients with pancreatic cancer is poor due to difficulty in early diagnosis and low resectability rate at the time of diagnosis. Apart from the progression of cancer, venous thromboembolism - a complication that can increase patient mortality - is known to occur frequently in pancreatic cancer. This review was aimed at identifying whether venous thromboembolism is more common in pancreatic cancer than in other cancer types. In addition, we reviewed several studies to determine whether thromboprophylaxis increases the survival rates of patients with pancreatic cancer.

Portal cavernoma cholangiopathy is defined as an obstruction of the biliary system due to distended veins surrounding bile ducts that mainly occur in patients with extrahepatic portal venous obstruction. The periductal venous plexuses encircling the ducts can cause morphological changes which may or may not become symptomatic. Currently, non-invasive techniques such as ultrasonography, computed tomography, magnetic resonance cholangiopancreatography, and dynamic contrast enhanced magnetic resonance images are being used to diagnose this disorder. Only a few patients who have symptoms of biliary obstruction require drainage which might be accomplished using endoscopic stenting, decompression of the portal venous system usually via a lienorenal shunt, a difficult direct hepaticojejunostomy, and rarely a liver transplant.
