Congenital Stenosis of the Inferior Vena Cava
Congenital Stenosis of the IVC

Presentation

OBJECTIVE: To present the prevalence, clinical, and imaging findings of interruption or congenital stenotic lesions of the inferior vena cava (IVC), associated malformations, and their clinical relevance. [ncbi.nlm.nih.gov]

These IVC anomalies may present with serious pathology that don’t correlate with the history of presenting complaint, across the age spectrum. [eposters.net]

Hepatomegaly may be present. [evtoday.com]

In the first case, typical double IVC was present (Fig. 9 ). [link.springer.com]

[…] heart defects may not show signs or symptoms until later stages of the child’s life and have a delayed diagnosis. [3] Congenital stenosis of the inferior vena cava is asymptomatic in many patients. [4] Adolescent males with the condition have shown to presents [en.wikipedia.org]

Workup

Hematologic workup also discovered a factor V Leiden mutation, further predisposing the patient to DVT. [dovepress.com]

Workup revealed liver cirrhosis. Imaging revealed prolapse of both transvenous leads into the inferior vena cava (IVC), resulting in complete obstruction at the level of the hepatic veins and large azygous collateralization. [innovationsincrm.com]

All patients with chronic iliocaval obstruction due to thrombus should undergo medical workup for hypercoagulability including antithrombin 3, protein C and S deficiencies, anticardiolipin antibody, lupus anticoagulant, prothrombin, MTHFR, and factor [vasculardiseasemanagement.com]

Treatment

The fulminant or chronic forms with irreversible hepatic damage require definitive treatment, such as orthotopic liver transplantation. [aetna.com]

Jugular vein access may be used for treatment of IVC lesions, but evaluation and treatment of distal disease is also more difficult from this approach. [vasculardiseasemanagement.com]

TREATMENT OF IVC OCCLUSIONS Although the specifics of treatment vary from patient to patient, there are some general principles governing the treatment approach. [evtoday.com]

Prognosis

Overall, mortality is high in the early phase of the disease but once the acute episode is terminated, prognosis is good. [karger.com]

Whether this would have altered the initial management or prognosis is open to debate. [jmedicalcasereports.biomedcentral.com]

These also constitute the indications for liver transplantation as they predict poor prognosis. In HVCS these symptoms occur before the development of cirrhosis or during early liver cirrhosis. [tropicalgastro.com]

The worse the patient’s liver function is, the worse their prognosis will be. This dangerous condition can be controlled if patients are compliant with dietary restrictions, and they abstain from alcohol and drugs. [hitachimed.com]

Patrick_Collier,_MD,_PhD: An echo is often performed in patients with arrhythmia to carefully assess for the presence of structural heart disease which can impact the prognosis and treatment of such symptoms. [my.clevelandclinic.org]

Etiology

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. [icd10coded.com]

[…] cava or renal veins or both, was first recognized and reported by Derow in 1939. 1 Pollak subsequently reported 13 cases with renal vein thrombosis. 2 Membranous obliteration of the hepatic portion of the inferior vena cava has been implicated in the etiology [jamanetwork.com]

In patients with iliac or IVC thrombosis, thrombolytics can be of help in delineating the underlying etiology of the occlusion (see Table 30–3 ), which then may be treated. [radiologykey.com]

Caval occlusion of malignant etiology is an insidious pathologic entity, resulting in substantial morbidity and limiting quality of life in severely ill and/or terminal patients. [evtoday.com]

Pathophysiology

Therefore, we subsequently sought for potential mechanisms by which iron may be linked to the pathophysiology of AS. [academic.oup.com]

However, more research must be conducted to determine the exact pathophysiological mechanism of action. In those patients found to have an IVC anomaly, clinicians must also evaluate patients for renal hypoplasia or horseshoe kidney. [dovepress.com]

Approach Considerations Once the diagnosis has been confirmed, the clinician must choose an appropriate treatment regimen for inferior vena cava (IVC) thrombosis (IVCT) on the basis of the underlying pathophysiology. [emedicine.medscape.com]

On presentation, patients should be evaluated on the Clinical, Etiologic, Anatomical, and Pathophysiological (CEAP) classification system 15,16 to grade the severity of CVD. [vasculardiseasemanagement.com]
