BACKGROUND: Cement augmented pedicle screw instrumentation (CAPSI) of the thoracolumbar spine is indicated in osteoporosis or osteopenia to improve pullout strength and biomechanical stability of pedicle screws (PS). Only few studies report on the incidence of pulmonary cement embolism or other complications associated with CAPSI. PURPOSE: Aim of this retrospective study was to assess the rate of CAPSI associated complications. STUDY DESIGN: Retrospective cohort study...

Deep vein thrombosis (DVT) with its major complication, pulmonary embolism, is a global health problem. Mechanisms of DVT remain incompletely understood. Platelets play a role in DVT but the impact of specific platelet receptors remains unclear. Platelet C-type lectin-like receptor 2 (CLEC-2) is known to maintain the physiological state of blood vasculature under inflammatory conditions. DVT is a thromboinflammatory disorder developing largely as sterile inflammation in the vessel wall. We hypothesized therefore that CLEC-2 might play a role in DVT...

Our aim was to describe the clinical indications, surgical technique, and clinical outcomes of a pancreas transplantation, performed 4 years after liver transplantation, as treatment for new-onset, uncontrolled diabetes mellitus in a 53-year-old man. Liver transplantation was performed for end-stage liver disease secondary to hepatitis B virus infection and hepatocellular carcinoma. The patient had no history of diabetes prior to the liver transplantation. The decision to proceed with a pancreas transplantation was made when the patient's blood sugar levels could not be normalized despite insulin doses >100 IU/d...

We report a case of extensive early postpartum acute suprarenal inferior vena cava thrombosis in a 14-year-old girl. Management included catheter-directed-thrombolysis, aiming to save renal function and prevent fatal pulmonary embolism. Treatment decisions were mostly based on adult guidelines, as guidelines for the paediatric population are not yet available.

Treatment of large, fresh thrombi in the vascular system can be challenging. AngioVac, a cardiopulmonary pump system, has been used to remove large thrombi and even some tumors by a percutaneous route. We report here a case of a 51-year-old man who presented with a large thrombus (7.5 × 1.5 cm) in his inferior vena cava, extending into his right atrium and right ventricle. Because the surgical risk was high, we attempted percutaneous embolectomy via the AngioVac aspiration system. We also review the literature concerning this emerging technique...

BACKGROUND The surgical technique used in pancreas transplant is essential for patient safety and graft survival, and problems exist with conventional strategies. When enteric exocrine drainage is performed, there is no method of immunologic monitoring other than direct graft pancreas biopsy. The most common cause of early graft failure is graft thrombosis, and adequate preventive and treatment strategies are unclear. To overcome these disadvantages, we suggest a modified surgical technique. MATERIAL AND METHODS Eleven patients underwent pancreas transplant with our modified technique...

The duplication of the inferior vena cava (IVC) is a rare congenital anomaly, which also has some variations regarding the complex embryological development of the IVC. In the typical form, infrarenal IVC segments are duplicated and the left IVC joins the left renal vein, which crosses anterior to the aorta in the normal fashion to join the right IVC. In variant forms, the interruption of the intrahepatic segment of the IVC, azygos or hemiazygos continuation, or retroaortic course of the renal vein may be seen...

BACKGROUND: Children with end-stage kidney disease may have co-existing iatrogenic or congenital vascular anomalies making transplantation difficult. We describe our approach in 5 recipients with vascular anomalies and significant co-morbidities, including one case of blood group incompatibility. METHODS: Five children aged 3 - 17 (median 7) years, weighing 14 - 34 (median 18) kg of whom 4 had occluded inferior vena cava or iliac veins and 2 had previous complex vascular reconstructions prior to transplantation for mid-aortic syndrome and multiple aortic aneurysms, respectively underwent renal transplantation...

Hydatid disease is a rare parasitic disease, which mainly involves liver then lung tissues. Cardiac involvement is very rare, especially when there is not hepatic involvement. We describe a 47-year-old woman with a history of a lung hydatid cyst who was referred to Rajaei Heart Center, Tehran, Iran in 2012. Her chest computed tomographic scan showed a cardiac mass. Echocardiographic examination illustrated a large, well-defined heterogeneous mass (4.5 × 2.5 cm) in the roof of the right atrium with attachment to the crista terminalis without compressive effect on the inferior and superior venae cavae...

BACKGROUND: Renal cell carcinoma (RCC) with isolated lymph node (LN) involvement has historically been associated with poor prognosis. However, a subset of patients may experience long-term survival. OBJECTIVE: To examine the natural history of RCC with isolated LN involvement following surgical resection with long-term follow-up, and to evaluate clinicopathologic features associated with disease progression and survival. DESIGN, SETTING, AND PARTICIPANTS: A total of 138 patients with isolated pN1M0 RCC underwent partial or radical nephrectomy and LN dissection from 1980 to 2010...

PURPOSE: A significant proportion of patients undergoing surgery have an increased incidence of acute pulmonary embolus (PE). We analyzed all patients who had a retrievable inferior vena cava (IVC) filter placed preoperatively for PE prophylaxis and investigated the long-term outcomes of the patients who did not have their filter removed. METHODS: Patients who underwent retrievable IVC filter insertion and attempted removal were identified from the radiology information systems database in a large tertiary referral university teaching hospital...

Cardiac metastasis from renal cell carcinoma (RCC) without inferior vena cava (IVC) involvements is extremely rare with few reported cases. Sarcomatoid RCC with rhabdoid feature is a rare pathologic type of RCC having aggressive behavior due to great metastatic potential. Here, we report a case of rapidly growing cardiac metastasis of RCC which brought on right ventricular outflow tract (RVOT) obstruction without IVC and right atrial involvement in a 61-year-old woman. Cardiac arrest occurred during radical nephrectomy and echocardiography revealed mass nearly obstructing the RVOT which was not recognized by preoperative echocardiography 1 month ago...

BACKGROUND: Ultrasound measurements of the inferior vena cava (IVC) diameter (IVCD), together with its respiratory variation, provide a noninvasive estimate of right atrial pressure (RAP). However, there is a paucity of studies that have compared this technique with simultaneous catheterization. We explored the best cut-off values of IVC parameters for elevated RAP in comparison with RAP measured by catheterization.Methods and Results:We prospectively enrolled 120 East Asian patients who were scheduled for catheterization...

BACKGROUND: This report presents a case of a 57- year old female with advanced Hepatic Alveolar Echinococcosis causing a secondary Budd-Chiari Syndrome due to infiltration of the suprahepatic inferior vena cava treated successfully by liver transplantation. CASE PRESENTATION: A temporary veno-venous bypass was introduced, but a typical end to end cavo-caval anastomosis wasn't possible in this case. In order to access a disease free part of the inferior vena cava, an oval window of the diaphragm was excised, providing communication between the peritoneum and pericardium...

BACKGROUND: Occlusion of vein grafts (VGs) after bypass surgery due to thrombosis and intimal hyperplasia (IH) is a major clinical problem. Apyrases are enzymes that scavenge extracellular ATP and ADP and promote adenosine formation at sites of vascular injury and hence have potential to inhibit vein graft pathology. OBJECTIVES: We examined the effects of recombinant soluble human apyrase, APT102, on platelets, smooth muscle cells (SMCs), and endothelial cells (ECs) in vitro and thrombosis and IH in murine VGs...

BACKGROUND: Long-axis images of the inferior vena cava (IVC) have limitations as surrogates for IVC morphology in grading central venous pressure (CVP) by two-dimensional echocardiography (2DE), because of the various cross-sectional morphologies and the translational motion of the IVC induced by sniffing. On the basis of the relationship between venous pressure and compliance, it was hypothesized that the cross-sectional morphology of the IVC, which was obtained using three-dimensional echocardiography, might estimate CVP more accurately compared with standard grading by 2DE...

The presentation of a patient with a pericardial effusion can range from an incidental finding to a life-threatening emergency. Accordingly, the causes of pericardial effusions are numerous and can generally be divided into inflammatory and non-inflammatory etiologies. For all patients with a suspected pericardial effusion, echocardiography is essential to define the location and size of an effusion. In pericardial tamponade, the hemodynamics relate to decreased pericardial compliance, ventricular interdependence, and an inspiratory decrease in the pressure gradient for left ventricular filling...
