BACKGROUND AND PURPOSE: Non-muscular myosin heavy chain IIA (NMMHC IIA) has been demonstrated to play a key role in tissue factor (TF) expression and venous thrombosis. However, whether natural products could inhibit thrombosis via NMMHC IIA remains unclear. In this study, we identified that a representative natural saponin D39 from Liriope muscari showed anti-thrombotic activity by targeting NMMHC IIA. EXPERIMENTAL APPROACH: TF expression and activity in endothelial cells were analysed in vitro by western blot and simplified chromogenic assays...

Renal cell carcinoma is the most lethal among all urological cancers. The lethality increases with advancing stages of the disease. Renal tumors show a peculiar propensity to invade the venous system. Such invasion not only worsens the disease prognosis but also increases the surgical morbidity making treatment of such tumors challenging. Several small volume series have been published regarding management and outcomes of renal tumors with inferior vena cava (IVC) thrombus which show encouraging results when addressed properly...

Women with complex congenital heart disease, such as those with single-ventricle physiology, are surviving into adulthood and becoming pregnant. Because of their complex physiology, common peripartum complications pose unique risks. We describe a patient with a single ventricle who underwent an external vascular conduit, nonfenestrated Fontan procedure in childhood and then presented during the postpartum period with extensive thrombosis in her lower extremity deep venous system and inferior vena cava. In this article, we will discuss single-ventricle physiology and the implications of pregnancy, anesthetic considerations, and data for maternal and fetal outcomes in this population...

OBJECTIVE: This study aims to investigate the clinical value of contrast-enhanced ultrasound (CEU) before temporary inferior vena cava filter (IVCF) recovery in patients with deep venous thrombosis, in order to provide ultrasound signs for the recovery of IVCF in clinical practice. METHODS: The CEU manifestations of patients with deep vein thrombosis before temporary IVCF recovery were retrospectively analyzed. With the manifestations of digital subtraction angiography (DSA) or results of the surgical recovery of IVCF as the standard, the detection rate of a thrombus in IVCF was compared between conventional ultrasound and CEU; and the role of CEU in detecting complications of IVCF was analyzed...

The inferior vena cava (IVC) is a rare site of focal atrial tachycardia (AT). Here, we report a 20-year-old woman who underwent catheter ablation for anti-arrhythmic drug-resistant AT originating from the IVC. She had undergone open-heart surgery for patch closure of an atrial septal defect 17 years previously and permanent pacemaker implantation for sinus node dysfunction 6 years previously. The AT focus was at the anterolateral aspect of the IVC-right atrial junction, and it was successfully ablated under three-dimensional electroanatomical-mapping guidance...

Background/Aims: Portal hypertension (PH) is a syndrome characterized by chronic increase in the pressure gradient between the portal vein and inferior vena cava. Previous studies have suggested an increased frequency of antral elevated erosive gastritis in patients with PH, as well as an etiologic association; however, there has not been any histological evidence of this hypothesis to date. Our aim was to evaluate the histological features found in elevated antral erosions in patients with portal hypertension...

This study aimed to assess the application of ultrasonography for preoperative diagnosis of retroperitoneal fibrosis (RPF). A total of 51 patients with clinically suspected RPF underwent transabdominal ultrasonography and ultrasound-guided histopathologic biopsy (tAU-UGHB). Retroperitoneal fibrosis was diagnosed in 35 patients; of these, 31 cases (88.6%) received a diagnosis using tAU-UGHB. The ultrasonographic images mainly showed solid, irregular isoechoic masses, which were present behind the retroperitoneum and surrounded the abdominal aorta, inferior vena cava, and ureters and had clear borders with the encapsulated structures...

Inferior vena cava injury as well as major liver injury remains a formidable treatment challenge. The most imminent danger is life-threatening bleeding. In this report, we present a case of polytrauma (Injury Severity Score 35) with arupture of the juxtahepatic inferior vena cava which was successfully treated using two-stage approach. The first part of the treatment consisted of damage control laparotomy at a level I trauma center. After stabilization, the patient was air-transported to receive the definitive treatment at a tertiary care facility experienced in hepatopancreatobiliary and transplantation surgery...

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) often infiltrates to the adjacent major vasculatures; however, direct invasion of PDAC to the inferior vena cava (IVC) is uncommon. CASE PRESENTATION: We report our experience with three cases of PDAC directly invading the IVC wall. All three patients underwent pancreatoduodenectomy along with wedge resection of the IVC wall without severe postoperative complications. Histopathological studies revealed tumor infiltration to the adventitia of the IVC...

Deep-vein thrombosis (DVT) is a common condition that often leads to pulmonary thromboembolism (VTE) and death. The role of prostaglandin-endoperoxide synthase (PTGS)2 in arterial thrombosis has been well established, whereas its impact in venous thrombosis remains unclear. Here, we showed that PTGS2 deletion predisposes to venous thrombosis as suggested by greater clot firmness and clot elasticity, by higher plasma levels of functional fibrinogen, factor VIII and PAI-1 activity, and proved by bigger thrombi detected after inferior vena cava ligation (IVCL) compared to WT mice...

This report describes the technical feasibility of using the filter eversion technique after unsuccessful retrieval attempts of Option and Option ELITE (Argon Medical Devices, Inc, Athens, Texas) inferior vena cava (IVC) filters. This technique entails the use of endoscopic forceps to evert this specific brand of IVC filter into a sheath inserted into the common femoral vein, in the opposite direction in which the filter is designed to be removed. Filter eversion was attempted in 25 cases with a median dwell time of 134 days (range, 44-2,124 d)...

BACKGROUND: Development of a high-fidelity cardiac surgery simulator (CSS) requires integration of a heart model with a mock cardiopulmonary bypass (CPB) circuit that can provide feedback to mimic the pathophysiology of cardiac surgery. However, the cost of commercially available simulators precludes regular use. We describe steps in the construction of a high-fidelity CSS that integrates a pulsatile paracorporeal ventricular-assist device (Pulse-VAD) and a commercially available CPB simulator...

Failure to remove a retrievable inferior vena cava (IVC) filter can cause severe complications with high treatment costs. Polydioxanone (PPDO) has been shown to be a good candidate material for resorbable IVC filters. However, PPDO is radioluscent under conventional imaging modalities. Thus, the positioning and integrity of these PPDO filters cannot be monitored by computed tomography (CT) or x-ray. Here we report the development of radiopaque PPDO IVC filters based on gold nanoparticles (AuNPs). Commercially available PPDO sutures were infused with AuNPs...
