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...

Retrocaval ureter or circumcaval ureter is a rare congenital abnormality arising from dysgenesis of the inferior vena cava (IVC) that results in the right ureter coursing behind and medial to the IVC. The ideal nomenclature for the anomaly is preureteral vena cava, keeping in mind the aberrant embryology. It can result in hydronephrosis and is a rare cause of long-standing cyclical pain abdomen. Ultrasound, intravenous urography, nuclear scintigraphy, computed tomography urography (CTU) and magnetic resonance urography (MRU) have been used in the diagnosis of this abnormality but CTU, with its ability to depict the abnormality in three dimensions gives the most "wholesome" solution to its diagnosis...

PURPOSE: Inferior vena cava filters (IVCFs) are used in patients with a high risk of pulmonary embolism in situations when the use of blood thinning drugs would be inappropriate. These filters are implanted under x-ray guidance; however, this provides a dose of ionizing radiation to both patient and physician. B-mode ultrasound (US) imaging allows for localization of certain implanted devices without radiation dose concerns. The goal of this study was to investigate the feasibility of imaging the placement of absorbable IVCFs using US imaging to alleviate the dosage concern inherent to fluoroscopy...

BACKGROUND: The intended physiologic response to a fluid bolus is an increase in stroke volume (SV). Several ultrasound (US) measures have been shown to be predictive. The best measure(s) in critically ill surgical patients remains unclear. METHODS: This is a prospective observational study in critically ill surgical patients receiving a bolus of crystalloid, colloid or blood. A transthoracic echocardiogram (TTE) was performed before (pre-TTE) and after. A positive volume response (+VR) was defined as a ≥15% increase in SV...

BACKGROUND: Routine management of patients with acute decompensated heart failure (ADHF) requires careful attentiveness to fluid status and diuretic treatment efficacy. New advances in ultrasound have made ultraportable echocardiography (UE) available to physicians for point-of-care use. The purpose of this study is to explore physiologic measures of intravascular fluid volume derived from UE and explore predictors of diuretic response in ADHF. METHODS: Various echocardiography imaging measurements, particularly diameter and collapse of inferior vena cava (IVC), were collected from 77 patients admitted with a primary diagnosis of ADHF...

OBJECTIVE: Percutaneous recanalization and stenting is currently the standard of care for symptomatic chronic total occlusions (CTOs) of the iliofemoral veins. CTO lesions involving the inferior vena cava (IVC) present a more complex patient subset. In this series we describe our single-center experience with endovascular recanalization of symptomatic occlusions of the IVC. METHODS: Patients were evaluated with duplex ultrasound imaging, venous function tests, and venography before intervention...

This paper deals with two recent cases of Inferior Caval Vein (IVC) duplicity, congenital anomaly often but not always asymptomatic that should be considered in the differential diagnosis of flank pain when other more common disorders have been excluded. Here are described the clinical and surgical significance together with the typical sonographic findings useful for the diagnosis of IVC duplicity. Particular attention is given to a peculiar and easily repeatable sonographic aspect associated with IVC duplicity, not previously reported in Literature and that we called the "Neptune's sign"...

BACKGROUND: Despite Point-of Care Ultrasound (PoC US) rapidly becoming an important tool in perioperative medicine structured education, PoC US is currently rarely integrated into the anesthesiology residency curriculum. The aim of this project was to assess the current ultrasound skills of anesthesiology residents at one institution and evaluate the needs for development of a formal ultrasound curriculum. METHODS: A event containing 6 different OSCE PoC US stations was developed with following stations: vascular, peripheral nerve block, lung ultrasound, transthoracic echocardiography (TTE) human model, pathologic TTE (simulator), and inferior vena cava (IVC) evaluation (simulator)...

BACKGROUND: Focused cardiac ultrasound (FoCUS) is accurate for determining the presence of a pericardial effusion. Using FoCUS to evaluate for pericardial tamponade, however, is more involved. Many experts teach that tamponade is unlikely if the inferior vena cava (IVC) shows respiratory variation and is not distended.

INSTRUCTION: Inferior vena cava (IVC) thrombosis can be a life-threatening complication after liver transplantation (LT). Although this complication is usually related to technical problems associated with vascular anastomosis, we report a case of IVC thrombosis which developed from a ligated large mesenteric-caval shunt. PRESENTATION OF CASE: A 35-year-old man underwent LT from a brain-dead donor for primary sclerosing cholangitis. Enhanced computed tomography (CT) before LT showed a huge collateral vessel of the inferior mesenteric vein (IMV) draining into the infra-renal IVC directly...

Low cardiac output after orthotopic heart transplant (OHT) may be attributed to inadequate preload, vasodilation, and/or reduced inotropy. Inadequate preload because of an inferior vena cava (IVC) thrombus is a rare cause of low cardiac output and not frequently described in the literature. Although the use of prothrombin complex (PCC) has been associated with thrombus formation, its contribution to life-threatening IVC thrombosis has yet to be described. This case report describes the use of perioperative ultrasound in the diagnosis and management of a low cardiac output state induced by an IVC thrombus in an OHT recipient who received PCC...

Congestive heart failure (CHF) is a major cause of morbidity and mortality. Early diagnosis of CHF in patients presenting to the emergency department (ED) with undifferentiated dyspnea would allow clinicians to begin appropriate treatment more promptly. Current guidelines recommend B-type natriuretic peptide (BNP) levels for more accurate diagnosis of CHF in dyspneic patients. Although BNP levels are relatively inexpensive, the test is not usually performed at bedside and results may take up to an hour or more...

Renal Vein Thrombosis (RVT) is a rarely encountered condition. It occurs due to a hypercoagulable state in the body, caused by nephrotic syndrome and membranous nephropathy in the adults. Mode of presentation is variable. In chronic form, it may remain silent for a long time and presenting later with symptoms of pedal oedema, varicocele, proteinuria. In acute state, it manifests as flank pain, nausea or haematuria. We present a case of 25-year-old male, with left sided flank pain, haematuria and nausea for 4 days...

BACKGROUND This study aimed to investigate the relationship between the inferior vena cava respirophasic variation (IVC collapsibility index [IVCCI]) and the general heart end-diastolic volume index (GEDVI). By determining the above relationship, we could evaluate the utility of IVCCI as an indicator. MATERIAL AND METHODS Forty-two septic patients were finally enrolled in this study. The inferior vena cava's diameter was measured with the largest at the end of expiration (IVC3) and with the smallest at the end of inspiration (IVCi) on the ultrasound (IVCCI=[(IVCD e - IVCD i)/IVCD e] ×100%)...
