Essential thrombocythemia is a chronic myeloproliferative disorder characterized by a sustained proliferation of megakaryocytes, which leads to increased numbers of circulating platelets. Hemorrhagic and/or thrombotic episodes are frequent, and thrombosis of both veins and arteries may develop. Vessels in unusual sites may be involved, e.g., the hepatic veins, mesenteric veins, and the dig...

leiomyosarcoma is one of the soft tissue sarcomas that could originate from different parts of body and are mostly presented as retropritoneal mass. leiomyosarcomas of vascular origin are particularly rare tumors occurring mainly in inferior vena cava (ivc). here, we report the case of a 35-year-old male patient who presented with ascites and jaundice. further evaluation revealed large hepatic ...

Congenital agenesis of the inferior vena cava is an uncommon congenital anomaly which can be misdiagnosed. Agenesis of the inferior vena cava has an incidence of 0.0005% to 1% in the general population [1]. The most common cause of agenesis of the inferior vena cava is the failure of embryological development between the sixth and the tenth weeks of gestation. Heterotaxy syndrome is associated ...

pulmonary adenocarcinoma is one of the major types of lung cancers in which metastasis is not uncommon. hereby, we report a case of pulmonary adenocarcinoma with multiple muscular, cutaneous, pancreatic and peritoneal metastases. actually, all these features occurring in one patient makes it an extraordinary case. a rare anatomic variation, double inferior vena cava (ivcs), was another rare man...

Background: Neonatal thrombotic diseases can cause mortality or serious morbidity and disability.Case report: In this report, we present a case of neonatal inferior vena cava thromboembolism with several underlyingfactors. Hereditary thrombophilia and genetic mutation in plasminogen activator inhibitor-1 and MTHFR A1298C genesin conjunction with cleft palate resulted in poor l...

The renal veins drain the kidney into the inferior vena cava and unite in a variable fashion to form the renal vein. The left renal vein is normally located in front of the aorta. However, the retro-aortic renal vein may course posterior to the aorta due to embryological developmental anomalies. During educational dissection, a rare variation of the left renal vein was found in a 66-year old ma...

Figure 1 Photographs (A; case 1 and B; case 2) and illustrations of Figure 1A (C) and Figure 1B (D) showing double superior vena cava: right connected to right atrium and left to the coronary sinus. pLSVC: persistent left superior vena cava; RSVC; right superior vena cava; CS: coronary sinus; LV: left ventricle; RA: right atrium; AA ascending aorta; IVC: inferior vena cava. In both cases, the v...

The benefits of a baffle fenestration in essentially high-risk Fontan patients have been demonstrated. Described here is the use of a new fenestration between the left atrial appendage and the left superior vena cava after Kawashima operation in a patient with a double-outlet right ventricle with hypoplastic left ventricle, left atrial isomerism, bilateral superior vena cavae with no bridging v...
