IVC collapsibility

Jie Zhao, Guolin Wang
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%)...

Intravertebral cleft (IVC) is a common finding in osteoporotic compression fracture. However, since the vertebral collapse attributable to cancer metastasis is rarely associated with IVC, the phenomenon is generally considered as a sign of a benign lesion. In this study, we retrospectively reviewed the radiographs, computed tomography scans, and magnetic resonance images of 111 patients with spinal metastasis. Three cases (2.7 %) had IVC in the collapsed thoracic vertebral bodies (T7, T8, and T11) attributable to cancer metastasis...

OBJECTIVE: To evaluate the correlation between central venous pressure (CVP) and inferior vena cava (IVC) diameters measured by ultrasonography (Ultrasound) in critically ill patients. METHODS: Intubated critically ill patients were enrolled. The CVP values were measured using a U-tube manometer and were compared to the IVC diameters and collapsibility index, which were measured by bedside Ultrasound. Patients younger than 18 years old, who were not intubated, who had an abdominal pressure greater than 12 mmHg, and/or who were admitted for trauma were excluded from the study...

The aim of the study was to explore the long- and short-axis dimensions, shape and collapsibility of the inferior vena cava in 46 trained and 48 untrained females (mean age: 21 ± 2 y). Echocardiography in the subcostal view revealed a larger expiratory long-axis diameter (mean: 24 ± 3 vs. 20 ± 3 mm, p < 0.001) and short-axis area (mean: 5.5 ± 1.5 vs. 4.7 ± 1.4 cm(2), p = 0.014) in trained females. IVC shape (the ratio of short-axis major to minor diameters) and the relative decrease in IVC dimension with inspiration were similar for the two groups...

BACKGROUND: Assessment of circulating volume and the requirement for fluid replacement are fundamental to resuscitation but remain largely empirical. Passive leg raise (PLR) may determine fluid responders while avoiding potential fluid overload. We hypothesised that inferior vena cava collapse index (IVCCI) and carotid artery blood flow would change predictably in response to PLR, potentially providing a non-invasive tool to assess circulating volume and identifying fluid responsive patients...

BACKGROUND: Central venous pressure (CVP) and right atrial pressure (RAP) are important parameters in the complete hemodynamic assessment of a patient. Sonographic measurement of the inferior vena cava (IVC) diameter is a non-invasive method of estimating these parameters, but there are limited data summarizing its diagnostic accuracy across multiple studies. We performed a comprehensive review of the existing literature to examine the diagnostic accuracy and clinical utility of sonographic measurement of IVC diameter as a method for assessing CVP and RAP...

Objective To address the role of transthoracic echocardiography in inferior vena cava (IVC) monitoring in the management of haemodynamically unstable elderly patients subjected to lower limb orthopaedic surgery under spinal anesthesia. Possible implications in the postoperative care unit (PACU) length of stay (LOS) are investigated. Methods 41 elderly patients with cardiac diseases were recruited. Patients experiencing intraoperative haemodynamic instability (diastolic blood pressure ≤ 60 mmHg) were divided into two groups according to right atrial pressure (RAP), (RAP < 5 mmHg and RAP between 5 and 10 mmHg) as measured by inferior vena cava collapsibility index (IVCCI)...

BACKGROUND: Fluid bolus administration is widely recommended as part of the initial treatment of paediatric sepsis, though the physiological benefits and harms are unclear. The primary aim of this study is to determine the effect of fluid bolus administration on cardiac index (CI). Secondary aims are to determine the effect of fluid bolus administration on extra-vascular lung water (EVLW), whether fluid responsiveness can be predicted by inferior vena cava (IVC) collapsibility, and whether fluid responsiveness correlates with changes in vital signs...

BACKGROUND: Both Framingham criteria and natriuretic peptides (NPs) may worsen their diagnostic validity for acute decompensated heart failure (ADHF) in elderly patients with comorbidities, mainly renal failure. Ultrasound of inferior vena cava (IVCu) and bioelectrical impedance analysis (BIA) are useful tools for detecting ADHF, although their utility compared with NP is not fully established. METHODS AND RESULTS: We conducted a prospective study with 96 patients who presented at the emergency department with dyspnea and were classified as ADHF and non-ADHF groups...

BACKGROUND: Appropriate fluid management is one of the most important elements of early goal-directed therapy after cardiothoracic surgery. Reliable determination of fluid responsivenss remains the fundamental issue in volume therapy. The purpose of the study was to assess the usefulness of dynamic IVC-derived parameters (collapsibility index, distensibility index) in comparison to passive leg raising, in postoperative fluid management in mechanically ventilated patients with left ventricular ejection fraction ≥ 30 %, immediately after elective coronary artery bypass grafting...

Few previous studies have monitored hemodynamic parameters to determine the physiological process of dengue or examined inferior vena cava (IVC) parameters to assess cardiac preload during the clinical phase of dengue. From January 2013 to July 2015, we prospectively studied 162 hospitalized adults with confirmed dengue viral infection using non-invasive cardiac output monitoring and bedside ultrasonography to determine changes in hemodynamic and IVC parameters and identify the types of circulatory shock that occur in patients with dengue...

Evaluations of intravascular fluid volume are considered to be one of the most important assessments in emergency and intensive care. Focusing on pulse-induced variation of the internal jugular vein (IJV) area, i.e., cardiac variation, we investigated its correlation with various hemodynamic indices using newly developed software. Software that automatically can track and analyze the IJV during ultrasonography was developed. Eleven healthy patients were subjected to an exercise load to increase their stroke volume (SV) and a dehydration load to decrease their central venous pressure (CVP)...

STUDY OBJECTIVES: Hypotension is a common side effect of propofol, but there are no reliable methods to determine which patients are at risk for significant propofol-induced hypotension (PIH). Ultrasound has been used to estimate volume status by visualization of inferior vena cava (IVC) collapse. This study explores whether IVC assessment by ultrasound can assist in predicting which patients may experience significant hypotension. METHODS: This was a prospective observational study conducted in the operating suite of an urban community hospital...

BACKGROUND: Fluid redistribution rather than fluid accumulation plays an important role in the development of acute heart failure (HF) syndrome. Patients with fluid redistribution develop acute HF without prominent volume overload. We investigated volume status by measuring the diameter of the inferior vena cava (IVC) and examining variations in hemoglobin and hematocrit. METHODS AND RESULTS: Seventy-four consecutive patients admitted for acute HF syndrome were analyzed...

Retained inferior vena cava (IVC) filters can lead to significant complications. Six patients underwent open surgical removal of complicated IVC filters that could not be removed endovascularly. Struts of the filter perforated the IVC wall in all patients and the adjacent viscera in five. Caval clamping and longitudinal cavotomy with direct closure were used in two patients to remove permanent filters. IVC clamping was not needed in three patients, in whom the filter was first collapsed and then removed through a stab venotomy in the IVC (n = 2) or lumbar vein (n = 1)...

BACKGROUND: Point-of-care ultrasound (POCUS) often includes cardiac ultrasound (CU). It is commonly used to evaluate cardiac function in critically ill patients, but lacks the specific quantitative anatomic assessment afforded by standard transthoracic echocardiography (TTE). We developed the Focused Rapid Echocardiographic Evaluation (FREE) - a hybrid between a CU and TTE that places an emphasis on cardiac function rather than anatomy. We hypothesized that data obtained from FREE correlates well with TTE while providing actionable information for clinical decision-making...

Point-of-care ultrasound has been increasingly used in evaluating shocked patients including the measurement of inferior vena cava (IVC) diameter. Operators should standardize their technique in scanning IVC. Relative changes are more important than absolute numbers. We advise using the longitudinal view (B mode) to evaluate the gross collapsibility, and the M mode to measure the IVC diameter. Combining the collapsibility and diameter size will increase the value of IVC measurement. This approach has been very useful in the resuscitation of shocked patients, monitoring their fluid demands, and predicting recurrence of shock...
