Caval vein thrombosis

Anticoagulation represents the first line treatment for venous thromboembolism (VTE). However, inferior vena cava (IVC) filter insertion can be considered as a possible therapeutic strategy when anticoagulant therapy is contraindicated, to avoid embolization from the lower limbs to pulmonary circulation. Other possible indications are debated among experts. Both permanent and retrievable caval filters are available in clinical practice. Retrievable filters can be removed when no longer necessary, as their use may be indicated only for a limited amount of time...

This study aimed to test the accuracy of a magnetic resonance imaging (MRI)-based method to detect and characterise deep venous thrombosis (DVT) in the ilio-femoro-caval veins. Patients with verified DVT in the lower extremities with extension of the thrombi to the iliac veins, who were suitable for catheter-based venous thrombolysis, were included in this study. Before the intervention, magnetic resonance venography (MRV) was performed, and the ilio-femoro-caval veins were independently evaluated for normal appearance, stenosis, and occlusion by two single-blinded observers...

OBJECTIVE: To evaluate the short-term outcomes and safety of syringe-assisted test-aspiration with mechanical aspiration thrombectomy in the treatment of deep venous thrombosis. METHODS: This was a single-center, retrospective study of hospitalized patients with iliofemoral and/or inferior vena caval deep venous thrombosis, excluding those with pulmonary embolism. We collected the following patient data from the electronic medical records: age, sex, provoked/unprovoked deep venous thrombosis, symptom duration, thrombosed segments, and the presence of a tumor, thrombophilia, diabetes, and/or iliac vein compression syndrome...

More than 10 million cases of venous thromboembolisms are reported on an annual basis and are major contributors to morbidity and mortality. Studies have found that ≤90% of pulmonary embolisms originate from the abdominal and lower extremity veins. The mainstay of venous thromboembolism treatment has been, and still continues to be, anticoagulation. However, for patients for whom anticoagulation is contraindicated or has failed, physicians have turned to surgical innovations such as inferior vena cava (IVC) filters to create partial interruption of the IVC...

BACKGROUND: Obstructive shock is extremely rare in clinical practice and is caused by acute blood flow obstruction in the central vessels of either the systemic or pulmonary circulation. Utilizing inferior vena cava filters (IVCFs) to prevent pulmonary embolism (PE) is associated with some potential complications, such as inferior vena cava thrombosis (IVCT). Shock as a direct result of IVCT is rare. We present a case of obstructive shock secondary to extensive IVCT caused by inadequate anticoagulant therapy after the placement of an IVCF...

BACKGROUND: Several orthotopic transcatheter strategies have been developed to treat severe tricuspid regurgitation (TR); however, many patients are deemed unsuitable. Caval valve implantation with the TricValve system addresses this unmet need. OBJECTIVES: This study sought to determine the impact of TricValve on systemic congestion and quality of life (QOL) at 1 year. METHODS: The TRICUS (Safety and Efficacy of the TricValve® Transcatheter Bicaval Valves System in the Superior and Inferior Vena Cava in Patients With Severe Tricuspid Regurgitation) and TRICUS EURO studies were prospective, nonblinded, nonrandomized, single-arm trials representing the early-in-man experience of the TricValve system in NYHA functional class III or IV severe TR patients, optimally medicated and ineligible for open heart surgery, with significant caval backflow...

Given in reperfusion, the use of stable gastric pentadecapeptide BPC 157 is an effective therapy in rats. It strongly counteracted, as a whole, decompression/reperfusion-induced occlusion/occlusion-like syndrome following the worst circumstances of acute abdominal compartment and intra-abdominal hypertension, grade III and grade IV, as well as compression/ischemia-occlusion/occlusion-like syndrome. Before decompression (calvariectomy, laparotomy), rats had long-lasting severe intra-abdominal hypertension, grade III (25 mmHg/60 min) (i) and grade IV (30 mmHg/30 min; 40 mmHg/30 min) (ii/iii), and severe occlusion/occlusion-like syndrome...

After inferior caval vein embolization therapy, post-embolization syndrome (sodium laurate 10 mg/kg, 0.1 mL into rat inferior caval vein, assessment at 15, 30, 60 min, prime lung lesions, thromboemboli occluding lung vessels), as a severe occlusion/occlusion-like syndrome, might be resolved as a whole by stable gastric pentadecapeptide BPC 157 therapy. At 5 min after laurate injection, stable gastric pentadecapeptide BPC 157 was implemented as therapy (10 µg/kg, 10 ng/kg intraperitoneally or intragastrically)...

INTRODUCTION: Outflow obstruction is a rare but critical vascular complication in liver transplantation, which may lead to graft loss and mortality. We report a case of caval vein outflow obstruction due to retrohepatic compression after living donor liver transplantation (LDLT), which was managed by temporary implantation of a vena cava filter. PRESENTATION OF CASE: A 63-year-old male with end stage liver disease presented with caval vein outflow obstruction and massive ascites 12 days after right lobe LDLT...

PURPOSE: This study investigated physician compliance with indications for inferior vena cava (IVC) filter placement according to the 2012 American College of Chest Physicians (ACCP) and the 2011 Society of Interventional Radiology (SIR) guidelines. MATERIALS AND METHODS: A retrospective medical record review of 231 retrievable IVC filters placed between August 15, 2016, and December 28, 2017, at a large urban academic medical center. Guideline compliance to the 2012 ACCP and the 2011 SIR guidelines, and indications for IVC filter placements were assessed through an adjudication protocol...

BACKGROUND: Pulmonary embolism (PE) is one of the most common causes of death from cardiovascular disease. Although deep vein thrombosis (DVT) is the leading cause of PE, its prognostic role is unclear. This study investigated the incidence and prognostic value of DVT in predicting in-hospital mortality (IHM) in patients admitted from the emergency department (ED) for PE. METHODS: This retrospective cohort study was conducted in the ED of a third-level university hospital...

BACKGROUND: Acute deep vein thrombosis (DVT) affects more than 350,000 patients each year in the United States. Contemporary rehospitalization rates and predictors of acute DVT have not been well characterized. We aimed to evaluate the all-cause 30 days readmission rate and its association with CDT and vena cava filters in patients with proximal and caval DVT. METHODS: Patients with index hospitalization for acute proximal lower extremity DVT were evaluated for unplanned readmission rates at 30 days using Nationwide Readmission Database from 2016 to 2017...

BACKGROUND: Using rat stomach perforation as a prototypic direct lesion applied in cytoprotection research, we focused on the first demonstration of the severe occlusion/ occlusion-like syndrome induced by stomach perforation. The revealed stomach-induced occlusion/occlusion-like syndrome corresponds to the previously described occlusion/occlusion-like syndromes in rats suffering multicausal pathology and shared severe vascular and multiorgan failure. This general point was particularly reviewed...

We focused on the first demonstration that antiarrhythmics, particularly class II and class III antiarrhythmic and beta-blocker sotalol can induce severe occlusion/occlusion-like syndrome in rats. In this syndrome, as in similar syndromes with permanent occlusion of major vessels, peripheral and central, and other similar noxious procedures that severely disable endothelium function, the stable gastric pentadecapeptide BPC 157-collateral pathways activation, was a resolving therapy. After a high dose of sotalol (80 mg/kg intragastrically) in 180 min study, there were cause-consequence lesions in the brain (swelling, intracerebral hemorrhage), congestion in the heart, lung, liver, kidney, and gastrointestinal tract, severe bradycardia, and intracranial (superior sagittal sinus), portal and caval hypertension, and aortal hypotension, and widespread thrombosis, peripherally and centrally...

OBJECTIVES: Chronically indwelling inferior vena cava filters (IVCFs) can have multiple adverse sequelae, including IVCF-associated IVC thrombosis. Inari ClotTriever and FlowTriever mechanical and aspiration thrombectomy systems (Inari Medical, Irvine, CA) can be used for acute caval thrombosis associated with IVCFs if appropriate proximal IVCF protection is used intra-procedurally. This study reports a single institution's outcomes following ClotTriever and FlowTriever thrombectomy of acute IVCF-associated iliocaval thrombus...

Even before behavioral disturbances, neuroleptics, amphetamine, and domperidone application rapidly emerged severe occlusion/occlusion-like syndrome, shared innate vascular and multiorgan failure in rats, comparable to occlusion/occlusion-like syndrome described with vessel(s) occlusion or similar noxious procedures application. As therapy, i.e., activation of the collateral pathways, "bypassing key" (activated azygos vein pathway, direct blood flow delivery), the stable gastric pentadecapeptide BPC 157 is a novel solution...

(1) Background: We aim to present our experience with resection of the inferior vena cava (IVC) without reconstruction in two patients diagnosed with renal tumors. (2) Case Report: The first case was diagnosed with right renal vein sarcoma and the second case was diagnosed with clear cell renal carcinoma; both presented signs of invasion and thrombosis of the IVC at infrarenal and cruoric levels, along with the development of collateral circulation with the help of the paravertebral plexus. In both patients, en bloc right nephrectomy was performed along with the resection of the thrombosed IVC without further reconstruction...

Phlegmasia alba dolens is a rare sequela of acute extensive venothrombus of the iliofemoral segments. Rarely, phlegmasia alba dolens can also result from clotted inferior vena cava filter. A 39-year-old with protein S deficiency, and prior inferior vena cava filter placement after remote trauma presented to the emergency department with progressive bilateral lower extremity pain and swelling. Venous duplex revealed extensive bilateral deep vein thromboses from the external iliac veins to popliteal veins, as well as thrombophlebitis of the left great saphenous vein...

OBJECTIVE: This study investigated the trend of venous thromboembolism (VTE) in China during the past 10 years and assessed the clinical application of inferior vena cava filters (IVCFs).
