An 85-year-old-woman presenting with low back pain developed shortness of breath and right-sided chest pain. She was found to have perfusion defects indicative of pulmonary embolus (PE). Heparin was at first employed, but had to be discontinued because of gastrointestinal bleeding. Caval filtration was the obvious course, but it was found on computed tomography (CT) scan that the suprarenal portion of the inferior vena cava was 55 mm in diameter, and the infrarenal portion 44 mm. These measurements were too large for insertion of a Greenfield filter, for which the maximum diameter should be 28 mm. The right common iliac vein was 28 mm in diameter, and the left external iliac vein 25 mm. Two filters were inserted percutaneously in these vessels. The patient was followed for 9 months. No clinical evidence of recurrent PE or venous insufficiency occurred.

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...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

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...

Hemodialysis I: Introduction

Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...
