Developmental Venous Anomaly Complicated by Cerebral Venous Infarction
Radiology Case Reports
|June 16, 2016
Summary
Developmental venous anomalies, a type of vascular malformation, can cause stroke. A case study shows a thrombosed draining vein in a developmental venous anomaly leading to neurological deficits.
Area of Science:
- Neurology
- Vascular Malformations
- Neuroscience
Background:
- Developmental venous anomaly (DVA) is a congenital vascular malformation, typically considered a benign embryologic variant.
- DVAs are the most common intracranial vascular malformations, often identified incidentally.
- While generally asymptomatic, DVAs can rarely be associated with neurological symptoms.
Observation:
- A patient presented with acute focal neurological deficits and paresthesia.
- Neuroimaging revealed an infarct in the brain parenchyma.
- The infarct was associated with a developmental venous anomaly exhibiting a thrombosed draining vein.
Findings:
- The patient's neurological deficits were attributed to an ischemic stroke.
- The stroke was directly linked to a thrombosed draining vein within the developmental venous anomaly.
- This case highlights a rare but serious complication of DVAs.
Implications:
- Developmental venous anomalies, despite their typical benign nature, can lead to significant neurological events like stroke.
- Thrombosis of the draining vein in a DVA is a critical factor in the development of infarcts.
- Increased awareness and vigilance are necessary for managing patients with DVAs, particularly those with atypical presentations or risk factors for venous thrombosis.

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...

422
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...

456
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...

The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...

01:26Varicose Veins I: Introduction
307
Varicose veins, or varicosities, are abnormally dilated and twisted superficial veins caused by venous valve incompetence. This condition commonly affects the lower extremities, especially the saphenous veins, due to the higher pressure from prolonged standing and walking. However, varicosities can also occur in other areas, such as the esophagus, vulva, spermatic cords, and anorectal region.Etiology and typesPrimary varicose veins, often idiopathic, are more common in women due to inherent...
