Introduction: Non Cirrhotic Portal Hypertension (NCPH) encompasses a wide range of disorders that are characterised by increased portal pressure with the absence cirrhosis liver. The classified anatomically based on site blood flow obstruction into prehepatic, hepatic and posthepatic causes. These numerous variable aetiological factors lack standardised diagnostic criteria, makes NCPH under-rec...

Budd-Chiari syndrome (BCS) encompasses a group of disorders caused by the obstruction to the hepatic venous outflow at the level of the small or large hepatic veins, the inferior vena cava, or any combination thereof. Clinical manifestation of the subacute form is characterized by supramesocolic abdominal discomfort, abdominal distension, fever, and lower limbs edema. Imaging work-up with hepat...

Superior vena cava (SVC) syndrome is not an uncommon occurrence in patients with malignancy and it is often described as a medical emergency. In majority of the cases, SVC syndrome occurs due to mechanical obstruction of the SVC by extraluminal compression with primary intrathoracic malignancies. However, intraluminal obstruction due to thrombosis can also produce symptoms and signs of SVC synd...

Hepatic vein outflow obstruction induces remarkable changes of intra-hepatic blood circulation; the significance of these changes remains uncertain. Six patients with obstruction of the hepatic veins were evaluated by duplex Doppler ultrasound and computed tomography. The adaptive changes secondary to obstruction were analyzed and their significance was correlated with the clinical findings. Fo...

paroxysmal nocturnal hemoglobinuria (pnh) is a rare hematologic disorder that manifests with hemolytic anemia, thrombosis, and peripheral blood cytopenias.acute abdominal pain is one of the pnh clinical manifestations due to venous thrombosis of intra-abdominal sites including hepatic, portal, mesenteric, and splenic veins.eculizumaband allogeneic bone marrow transplantation (bmt) arethe only w...

Total anomalous pulmonary venous connexion may be conveniently classified into supradiaphragmatic and infradiaphragmatic types (Smith, Frye, and Newton, I96I). Infradiaphragmatic forms are usually associated with obstruction to pulmonary venous flow (Johnson et al., I958) and the supradiaphragmatic types are said only rarely to have pulmonary venous obstruction (Lucas et al., I963). However, ob...

BACKGROUND To study iliofemoral venous thrombosis related to iliofemoral venous obstruction in cancer patients. METHODS In this case series study, 829 cancer patients were surveyed for iliofemoral obstruction/thrombosis within 10 years. The criteria for inclusion were: (1) presence of unilateral lower-extremity swelling; (2) computed tomography (CT) scans showing a tumor with external compres...
