Abstract:

Symptomatic retrograde thrombosis of afferent arteries is a rare complication from the excision of cerebral AVMs. Advanced
age, large-size AVMs, long and dilated afferent feeding arteries and possibly preoperative hemorrhage are pointed
out as risk factors. Degenerative changes of afferent arteries of AVMs and blood stasis following microsurgical resection
seem to play an important role in the pathophysiology of this complication. A few reports have associated cerebral venous
thrombosis with various forms of spinal meningeal injury. However, it has been rarely documented following spinal surgery
complicated by accidental durotomy or external lumbar CSF drainage. CSF hypovolemia may precipitate CVT in patients
having prothrombotic risk factors. Patients who have or had CSF leaks or lumbar CSF drains who present with symptoms of
intracranial CSF hypotension should remain in the horizontal position to prevent CVT. In that context, the diagnosis of CVT
depends on a high degree of suspicion. New insights into the etiology, pathophysiology, diagnosis and prevention of these two
rare entities are presented along with illustrative cases.
