Inserting a VA-ECMO cannula through an inferior vena cava filter during extracorporeal cardiopulmonary resuscitation.

Venoarterial extracorporeal membrane oxygenation (VA-ECMO) has been utilized to treat massive pulmonary embolism (PE) accompanied by cardiac arrest or refractory cardiogenic shock. Our team opted for a femoral-femoral approach for vascular cannulation, using drainage and return cannulas in the common femoral vein and artery, respectively. However, femoral venous cannulation can be limited or challenging due to the presence of thrombus in the inferior vena cava (IVC), making the insertion of the drainage cannula via the femoral vein difficult.

Unexpected normal ROTEM results in protein C deficiency with IVC thrombosis.

Protein C deficiency is a hereditary disorder that increases the risk of thrombotic events but has unclear effects on rotational thromboelastometry (ROTEM) analysis. A man in his 60s with a history of protein C deficiency and multiple thrombotic events underwent inferior vena cava (IVC) filter removal, iliocaval thrombectomy and infrarenal IVC placement for IVC-related complete iliocaval and common femoral vein thromboses. A ROTEM analysis showed normal coagulation in NATEM and EXTEM and only a slight shortening in A10 and A20 in INTEM, which was unexpected given his diagnosis of protein C deficiency.

Suprarenal interrupted inferior cava with azygos continuation in a patient with pulmonary embolism: a case report.

Background: Interrupted inferior vena cava (IVC) is a rare developmental defect characterized by azygos continuation following failure of fusion of one or more of the component parts of the embryological IVC. It occurs in approximately one in 5000 of the general population. It is usually an isolated finding and is generally asymptomatic.

Validating International Classification of Diseases Code 10th Revision algorithms for accurate identification of pulmonary embolism.

Background: Many research investigations for pulmonary embolism (PE) rely on the International Classification of Diseases 10th Revision (ICD-10) codes for analyses of electronic databases. The validity of ICD-10 codes in identifying PE remains uncertain.

Objectives: The objective of this study was to validate an algorithm to efficiently identify pulmonary embolism using ICD-10 codes.

Blood Loss in Women of Childbearing Potential Taking Oral Anticoagulants for Venous Thromboembolism (The BLEED Study).

Background:  Oral anticoagulants (OAC) may exacerbate menstrual bleeding in women of childbearing age; however, the existing literature on this issue has several limitations.

Materials And Methods:  This study investigates abnormal uterine bleeding in women of childbearing age taking OAC-vitamin K antagonists or direct oral anticoagulants-for venous thromboembolism through a retrospective analysis of prospectively collected data. Uterine bleeding was assessed using the Pictorial Blood Assessment Chart (PBAC) and hemoglobin (Hb) values during anticoagulation compared with prior therapy.

Clinical Application of DynaCT in the Study of Vascular Neointimal Hyperplasia Characteristics after Option Filter Placement.

Objective: The objective of this study was to analyze neointimal hyperplasia of the inferior vena cava (IVC) after Option filter implantation by DynaCT and to provide a reference for the safety of effective neointimal hyperplasia cutting after long retrieval window filter implantation in vivo.

Methods: Clinical data on 22 patients with Option filters were retrospectively analyzed. DynaCT was used to analyze the characteristics of neointimal hyperplasia after filter implantation, including the distribution of neointimal hyperplasia and the maximum thickness of the neointimal hyperplasia.

Open and endovascular treatment of the common femoral artery in a tertiary care center.

Objectives: Endovascular treatment of peripheral arterial disease involving the common femoral artery (CFA) remains controversial. This study compares the perioperative and long-term outcomes of open and endovascular lower extremity revascularization (LER) involving the CFA.

Methods: A retrospective analysis of all patients undergoing LER for peripheral arterial disease in a tertiary care center was performed.

Obstructive Shock in Acute Vena Cava Filter Thrombosis: A Rare Presentation.

Inferior vena cava (IVC) filters are commonly placed to prevent the development or worsening of pulmonary emboli. They are also inherently thrombogenic. Here we discuss a case of acute IVC filter thrombosis with the unusual presentation of obstructive shock resulting in death.

Efficacy and safety of a novel vena cava filter on pulmonary embolism prophylaxis: a prospective, multicenter, randomized, parallel, positive-controlled, noninferiority clinical trial.

Background: There are different types of vena cava filter (VCF) available in clinical practice. However, limited data exist to determine whether one type is superior to another, and no single VCF is universally recommended in clinical guidelines. The objective of this study was to investigate the safety and efficacy of a novel VCF, Octoparms, for the prevention of pulmonary embolism (PE) and to compare it with the Celect filter.

Treatment of penetrating injuries of the retrohepatic vena cava: systematic review protocol.

Injuries to the retrohepatic segment of the inferior vena cava require complex procedures, as exposure without prior vascular control can lead to uncontrollable and fatal bleeding. To achieve such control, the classic techniques of hepatic vascular exclusion and the implantation of an atriocaval shunt have been described, and more recently, endovascular strategies have been reported. However, there is no consensus in the literature regarding which of these strategies is associated with lower mortality.

Venous Thromboembolism after Hospital Discharge: Temporal Trends in Baseline Characteristics, Prevention, Treatment, and 90-day Outcomes.

Venous thromboembolism (VTE) after hospital discharge poses a serious health risk. Assessments of patient characteristics, prophylaxis, treatment, outcomes, and over time changes lack consistency. Data on 16,901 hospitalized patients in the Registro Informatizado Enfermedad TromboEmbolica registry (2003-2022) were analyzed to evaluate trends in baseline characteristics, prophylaxis, treatments, and 90-day outcomes among medical (6,218) and surgical (10,683) patient cohorts.

Management of antithrombotic therapy in patients undergoing dental procedures.

A growing number of patients receiving antithrombotic therapy require dental procedures. Dental interventions in these patients can be challenging, as the risk of bleeding from the continuation of antithrombotic therapy needs to be weighed against the thromboembolic risk associated with drug interruption or de-escalation. Most minor dental procedures, including simple dental cleaning and filling, pose minimal bleeding risk, and antiplatelet or anticoagulation therapy can be continued without interruption.

Surgical Strategies and Perioperative Outcomes of Robot-Assisted Vena Cava Reconstruction.

Background: This study aimed to describe robot-assisted vena cava reconstruction by summarising surgical strategies and perioperative outcomes.

Methods: A retrospective review was performed on all robotic surgeries involving dissection and repair of the inferior vena cava (IVC) at our institution. Patient characteristics, operative reports, and follow-up visits were analysed.

Thrombus Burden, Caval Thrombosis, and Retrieval of the Denali Inferior Vena Cava Filter.

The purpose of this study was to evaluate outcomes of the Denali inferior vena cava filter (Bard Peripheral Vascular, Tempe, Arizona). Five hundred patients had 508 filters placed between 2015 and 2022. Filters were retrieved at the study site in 284 patients: 159 (31.

The impact of diabetes mellitus on the outcomes of revascularization for chronic limb-threatening ischemia in the BEST-CLI trial.

Objective: Several observational studies have demonstrated an association between diabetes mellitus (DM) and above-ankle amputation after lower extremity revascularization (LER). However, data from prospective randomized trials is lacking. This analysis compares the outcomes of patients with and without DM enrolled in the Best Endovascular vs Best Surgical Therapy in patients with Chronic Limb-Threatening Ischemia (BEST-CLI) trial.

Pharmacokinetic and Pharmacodynamic Interactions between Food or Herbal Products and Oral Anticoagulants: Evidence Review, Practical Recommendations, and Knowledge Gaps.

Interactions between food and oral anticoagulants (OACs), particularly vitamin K antagonists such as warfarin, are widely recognized and may also be clinically relevant for direct OACs. Pharmacokinetic and pharmacodynamic interactions with food or herbs can lead to anticoagulation potentiation, increased risk of bleeding, or reduced drug efficacy, all compromising patient safety. We conducted a systematic search for randomized controlled trials (RCTs) on PubMed for assessments of interactions between OACs and various ingestants.

Endovascular recanalization for filter-bearing inferior vena cava occlusion in a dialysis patient.

Central venous occlusion (CVO) or stenosis (CVS) is a common complication of long-term hemodialysis catheters. Endovascular intervention, primarily balloon angioplasty and occasionally stent placement, is the primary approach for managing CVS/CVO lesions. The presence of a filter within the inferior vena cava (IVC) lumen makes recanalization of the IVC more challenging.

Appropriateness guidelines for inferior vena cava filter utilization: A contemporary review.

Concern regarding the exponential increase in optional utilization of inferior vena cava filters (IVCFs) in the early 2000s with a persistent low retrieval rate nationwide has resulted in increased scrutiny regarding clinical application of IVCFs. IVCFs are used in a variety of clinical scenarios, ranging from thromboembolic protection in patients with deep venous thrombosis and contraindication to anticoagulation to prophylactic deployment in multitrauma and critically ill patients. Evidence supporting IVCFs as mechanical thromboembolic protection in certain clinical scenarios has been established through evidenced-based guidelines.

Finding the Balance: Venous Thromboembolism Prophylaxis during Hematochezia in Crohn's Disease.

Introduction: Despite heightened risk of venous thromboembolism (VTE) in hospitalized patients with inflammatory bowel disease (IBD), pharmacologic prophylaxis remains underutilized, particularly in those presenting with hematochezia. Although placement of retrievable inferior vena cava filters (rIVCF) may be considered in those with contraindications to anticoagulation and VTE risk, current recommendations from clinical guidelines are incongruent, leading to wide variation in practice.

Case Presentation: This report highlights a case of rIVCF used in the management of recurrent VTEs in a patient hospitalized for persistent gastrointestinal bleeding.
