Chapter 13: Neurovascular Healing and Thromboembolic Disease

These flashcards cover key terms from Chapter 13 on neurovascular healing and thromboembolic disease, useful for exam preparation.

Neurapraxia

Temporary conduction block, reversible.

Axonotmesis

Axonal disruption with intact epineurium.

Neurotmesis

Complete nerve transection.

Neurorrhaphy

Surgical nerve repair.

Vasa nervorum

Blood supply to nerves.

Creep

Time-dependent tissue deformation.

Virchow’s triad

Hypercoagulability, stasis, vessel injury.

Deep vein thrombosis (DVT)

Deep venous clot.

Pulmonary embolism (PE)

Embolus in pulmonary artery.

Epineurium

Outermost protective sheath of peripheral nerves.

Perineurium

Surrounds fascicles of nerves.

Endoneurium

Surrounds individual axons.

Viscoelastic Properties

Nerves deform with sustained load.

Load-to-Failure

Failure occurs at 20–60% elongation.

Neurorrhaphy

Direct surgical coaptation of nerve ends.

Nerve Grafting

Used when direct repair causes excessive tension.

Double Crush Syndrome

Compression at multiple sites along the same nerve.

Medical Research Council Scale

Scale to assess recovery in motor and sensory function.

Virchow’s Triad

The three factors that lead to thrombosis: hypercoagulability, stasis, vessel wall injury.

Doppler ultrasound

A diagnostic study used to assess vascular conditions.

Heparin

A common pharmacological treatment for venous thromboembolism.
