Venous Thrombosis Has a Constellation of Different Risk Factors: A Case Report and State-of-the-Art Review.

Splanchnic venous thrombosis and cerebral venous thrombosis are uncommon manifestations of venous thromboembolism (VTE) that have been associated with inherited thrombophilias. Hyperhomocysteinemia is an established risk factor for thrombosis, and methylenetetrahydrofolate reductase (MTHFR) mutation is the most common genetic alteration in this condition. The association between MTHFR mutations, mild to moderate elevations in homocysteine, and the risk for thrombosis is controversial. Pylephlebitis, also known as suppurative portal vein thrombophlebitis, usually originates from an intra-abdominal infectious process. It is a condition with high morbidity and mortality, partly due to its late diagnosis, and antibiotics are the gold standard treatment. The purpose of anticoagulation is dubious. We describe the case of a 60-year-old male with a previous history of venous sinus thrombosis and MTHFR A1298C mutation with mild homocysteine ​​elevation who presented with signs and symptoms of intra-abdominal infection and whose abdominopelvic computed tomography (CT) with intravenous contrast showed splanchnic-vein thrombosis. Through this complex case, the authors present a review of the current state of the art on VTE, hyperhomocysteinemia, and pylephlebitis, emphasizing the need for a holistic view of the patient in the decision-making process.

Symptomatic bilateral coronary artery fistula to pulmonary artery in elderly patient.

We report the imaging findings of an uncommon coronary vascular termination anomaly, with fistula to the pulmonary artery. This 70 year old female patient presented unstable angina, showing a coronary artery fistula depicted in coronary angiogram from the left coronary to the pulmonary artery, with no significant atherosclerotic pathology. Due to development of ventricular tachycardia in stress echocardiogram examination, she was proposed for coronary fistula closure. Coronary CT was performed for procedure planning and allowed the identification of a second unsuspected fistula from the right coronary to the right pulmonary artery. Congenital coronary anomalies are a possible cause of symptomatic coronary pathology in patients of any age. In older patients, coronary artery fistulas are rare, especially when symptomatic. Adequately performed CT examinations, using its post processing capabilities, with 3D and MIP reconstructions are invaluable in delineating coronary anatomy, essential for further treatment planning.

Collteral loop approach from left to right liver lobe: Endovascular recanalization of a hepatic vein in Budd-Chiari syndrome.

We report the approach to a 29 year old patient presenting with the diagnosis of a Budd-Chiari Syndrome, with clinical deterioration after initial anticoagulation treatment. The patient was proposed to endovascular treatment. Through intra-hepatic shunting seen at angiography, and from a left to right liver lobe, a guide-wire was passed retrogadely and allowed sufficient support to perform hepatic vein angioplasty and stenting. The patient responded favourably and liver transplant was avoided.
