Summary
Inferior vena cava (IVC) thrombosis can cause cauda equina syndrome, leading to back pain and leg weakness. Prompt IVC thrombectomy improved symptoms in a 16-year-old patient.
Area of Science:
- Neurology
- Vascular Surgery
- Radiology
Background:
- Cauda equina syndrome (CES) is a rare neurological condition often caused by spinal stenosis or disc herniation.
- Inferior vena cava (IVC) thrombosis, a condition involving blood clots in the large vein that carries deoxygenated blood from the lower and middle body into the liver into the heart, is typically associated with lower extremity swelling and pain.
Observation:
- A 16-year-old female presented with acute low-back pain, bilateral leg pain and weakness, and paresthesias.
- Magnetic resonance imaging (MRI) and MR venography revealed epidural venous plexus engorgement and mild cauda equina compression.
- Pelvic and lower extremity venography demonstrated extensive thrombosis of the iliac veins, femoral veins, and the IVC.
Findings:
- The patient underwent an IVC thrombectomy due to progressive neurological deficits.
- Post-operatively, the patient experienced rapid improvement in symptoms and returned to baseline function within one week.
- Follow-up imaging confirmed resolution of venous engorgement and cauda equina decompression.
Implications:
- This case highlights a rare but significant association between IVC thrombosis and CES.
- Early recognition and intervention, including thrombectomy, may be crucial for managing CES secondary to IVC thrombosis.
- Further research is warranted to elucidate the pathophysiology and optimal management strategies for this condition.

01:18Veins 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...

01:24Esophageal Varices-I: Introduction
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...
01:30Venous Thrombosis I: Introduction
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
01:20Venous 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...
01:29Venous 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...
01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
