Insights

Inferior vena cava (IVC) filter retrieval is safe, even for patients on anticoagulation. This study found no increased risk of major complications in anticoagulated patients undergoing IVC filter removal.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Cardiovascular Medicine

Background:

  • Inferior vena cava (IVC) filters are used to prevent pulmonary embolism.
  • Retrieval of IVC filters is a common procedure.
  • The safety of IVC filter retrieval in patients on anticoagulation is not well-established.

Purpose of the Study:

  • To assess the safety of IVC filter retrieval in patients taking anticoagulation.
  • To compare complication rates in anticoagulated versus non-anticoagulated patients undergoing IVC filter retrieval.

Main Methods:

  • Retrospective cohort study of 357 patients undergoing IVC filter retrieval.
  • Data collected included patient demographics, anticoagulation status, and complications.
  • Major complications included IVC injury, filter fracture, and embolization.

Main Results:

  • IVC filter retrieval was technically successful in 349 patients (97.8%).
  • Five major complications (1.4%) occurred: two in the anticoagulated group (1.1%) and three in the non-anticoagulated group (1.7%).
  • No minor complications were recorded.

Conclusions:

  • IVC filter retrieval is a safe procedure with a low complication rate.
  • Anticoagulation status does not increase the risk of major complications during IVC filter retrieval.
  • IVC filter retrieval can be safely performed in patients on prophylactic or therapeutic anticoagulation.

Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants

Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

Tertiary Healthcare System01:21

Tertiary Healthcare System

Specialized care provided over an extended period is called tertiary care. Usually, a primary or secondary care physician will refer a patient to tertiary care. A patient's maximum physical and mental function is restored in tertiary care, which is caused due to the impact of a chronic illness or condition. Tertiary care aims to achieve the highest level of functioning possible while managing chronic illness. For example, a patient who falls and fractures their hip will need secondary care...

Retrieval01:12

Retrieval

Retrieval is the process of getting information out of memory storage and back into conscious awareness. This ability is essential for daily tasks like brushing hair and teeth, driving to work, and performing job duties. Retrieval occurs in three ways: recall, recognition, and relearning.
Recall involves accessing information without cues, such as during an essay test, where individuals must retrieve facts and concepts from memory unaided. Another example is remembering the name of a colleague...

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Nomenclature of Secondary and Tertiary Amines01:12

Nomenclature of Secondary and Tertiary Amines

The secondary and tertiary amines are derivatives of ammonia, where two and three of its hydrogens are replaced by alkyl groups, respectively. Secondary and tertiary amines can be symmetrical with identical alkyl groups attached to the nitrogen atom or unsymmetrical when more than one type of alkyl group is present. The standard nomenclature of secondary and tertiary amines is similar to the names given to the primary amines. They are generally named alkylamines. As depicted in Figure 1, for...
