Agenesis of inferior vena cava (IVC)is a rare cardiovascular malformation that occurs between the sixth and tenth week of embryogenesis. It may be associated with cardiac and abdominal malformations, besidescomplications such as deep vein thrombosis (DVT). The present study reports the case of a patient randomly diagnosed with total IVC agenesis associated with malformation of the portohepatic system and polysplenia. Female patient, 9 years old, being monitored for hemorrhagic dengue, withcomputed tomographyand abdominal ultrasound revealing anomaly of the development of the hepatic portal system associated with the absence of inferior vena cava with continuation inretrocrural azygos vein, in addition to multiple accessory spleens. When the anastomoses of the IVCprimitive veins are not formed properly, partial or total agenesis of this vessel may occur. Consequently, the blood is diverted to the retrocrural azygos. Identification of these malformations is important for the patients receive proper guidance about DVT prevention, in additionto monitoring them for diagnosis of other possible malformations.

Abstract Case A 74 year-old white male with COPD, type 2 Diabetes, Atrial Fibrillation and a Pacemaker presented to our hospital for a routine echocardiography follow-up for mild to moderate Aortic Stenosis. His past social history was positive for moderate alcohol consumption but negative for tattoos, recent travel, illicit drug use, blood transfusion or chemical exposure. During evaluation in the echocardiography lab the patient had symptoms of dyspnea, fatigue and abdominal distension. He was hemodynamically stable and physical examination was positive for signs os ascites and inferior limb oedema, but disclosed no scleral icterus, asterixis, spider angiomata or overt hepatomegaly. There was a recent weight gain of 10kg. Cardiac and pulmonary auscultation was unrevealing. The echocardiogram revealed moderate left ventricle dysfunction (EF ∼40%), moderate aortic stenosis and a dilated inferior vena cava (31mm) with an image of a mobile mass in the confluence of the central hepatic vein with the inferior vena cava with extension to the right atrium. Initial blood chemistry and blood count revealed macrocytic anaemia; slight increased y-GT, C-reactive protein and NT-proBNP (6210pg/mL). The patient was admitted and anticoagulation with subcutaneous enoxaparin was initiated with echocardiographic follow-up. An abdominal ultrasound was performed which a hyperecogenic mass (71x47mm) adjacent to the right and left supra-hepatic veins, highly suggestive of hepatocelullar carcinoma. A triple-phase abdominal CT confirmed a nodular lesion 70x50mm on segment VIII, compatible with hepatocellular carcinoma (Fig.1). A cardiac magnetic resonance was performed documenting the tumor extension to the inferior vena cava and right atrium, suggestive of tumor thrombus (Fig.2). Multidisciplinary meeting enrolled the patient in palliative care. The right heart failure picture was refractory to medical treatment and the patient progressed to multi organ failure and a consumptive state. He died approximately 20 days after diagnosis. Discussion Intravascular tumor extension, also known as Tumor thrombus (TT) is a rare complication of some forms of cancer. In the late stages of Hepatocellular carcinoma (HCC) a TT can form in the portal or hepatic vein. These are usually detected during tumor workup or during evaluation of cardiorespiratory symptoms in a patient with a known abdominal carcinoma. Tumor invasion to the portal system is quite common while invasion to the inferior vena cava (IVC) and/or heart without invasion of the portal system is rare. Tumor extension to the RA or IVC, most patients were either symptomatic, had cirrhosis, or both. Our patient presented mainly with signs of right heart failure refractory to medical treatment and had no signs of portal invasion or hypertension in the various image modalities. The prognosis for a HCC with extension to the IVC or RA is grim, with a 1 to 4 months of mean survival regardless of treatment choice. Abstract P883 Figure.
