Venous Thrombosis III: Interprofessional Care01:29

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
Veins of the Abdomen and Pelvis01:18

Veins of the Abdomen and Pelvis

The human body is a complex system of interconnected parts, and the circulatory system plays a crucial role in maintaining overall health. One key component of this system is the inferior vena cava, a large vein responsible for returning blood from the abdominopelvic viscera and abdominal walls to the heart.
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...
Overview of Systemic Veins01:11

Overview of Systemic Veins

Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the middle...
Veins of Thorax01:19

Veins of Thorax

The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.

Overview of Systemic Arteries01:11

Overview of Systemic Arteries

The human body is a complex, well-organized machine, and at the heart of its operations lies the circulatory system. This network of blood vessels, which includes systemic arteries, plays a vital role in maintaining life by transporting nutrients, oxygen, and waste products to and from cells throughout the body.
Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body's tissues and returns deoxygenated blood back to the heart.
Venous Return01:04

Venous Return

The circulatory system plays a crucial role in ensuring the optimal functioning of the human body. One of its critical components is venous return - the process that completes the blood circulation cycle. This article will delve into the concept of venous return, how it works, and its significance to our health.
What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system as it...

Area of Science:

  • Critical Care Medicine
  • Vascular Surgery
  • Thrombosis Management

Background:

  • Anticoagulation is standard for venous thromboembolism (VTE) but contraindicated or ineffective in some critically ill patients.
  • Recurrent VTE occurs despite adequate anticoagulation in a subset of critically ill individuals.
  • Vena cava filters present an alternative VTE prophylaxis and treatment strategy.

Purpose of the Study:

  • To review the indications, techniques, and complications associated with vena cava filter use in critically ill patients.
  • To highlight the advantages of retrievable vena cava filters.
  • To emphasize the feasibility and importance of bedside insertion in the intensive care unit.

Main Methods:

  • Review of current literature on vena cava filter use in critically ill populations.
  • Analysis of indications for filter placement, including contraindications to anticoagulation and recurrent VTE.
  • Examination of filter insertion techniques, focusing on bedside procedures.
  • Assessment of filter-related complications and retrieval outcomes.

Main Results:

  • Vena cava filters are indicated for critically ill patients with contraindications to anticoagulation or recurrent VTE.
  • Filter insertion techniques, including bedside procedures, are feasible in the intensive care unit.
  • Retrievable filters offer the potential for temporary protection, reducing long-term complications.
  • Complications associated with filter placement and retrieval are reviewed.

Conclusions:

  • Vena cava filters are a valuable option for VTE management in select critically ill patients.
  • Retrievable filters and bedside insertion enhance the safety and applicability of this intervention in intensive care settings.
  • Careful patient selection and procedural technique are crucial for optimal outcomes.
