Surgical Management of Cavernous Malformations and Venous Anomalies
2021, Stroke: Pathophysiology, Diagnosis, and ManagementEvolution of Developmental Venous Anomalies in the Setting of a Torcular Dural Arteriovenous Fistula and Cerebrofacial Venous Metameric Syndrome
2020, World NeurosurgeryCitation Excerpt :Given their pivotal and critical role as compensatory connection between the “deep” and the “superficial” venous systems (with the direction of flow dictated by the primary underlying phenomenon) in a situation of altered drainage, interruption of this critical pathway has disastrous consequences that have been known to surgeons for many years.10 Careful analysis of angiograms in patients with large DVAs shows an absence of the normal venous drainage with the DVA representing a compensatory anatomically enlarged vein.10 The patient's clinical condition was further complicated by the presence of multiple de novo cavernous malformations, some of which clearly developed in the venous radicles of the growing DVA.
Surgically Treated Epilepsy due to Developmental Venous Anomaly of the Brain: Case Report and Review of the Literature
2020, World NeurosurgeryCitation Excerpt :Venous infarction followed, resulting in prolonged hospitalization and permanent neurologic deficit. Senegor et al.19 reported a case of surgically treated large fourth ventricular DVA. The draining veins were clipped, and the patient did not wake up after surgery and died 4 days later.
Long-Term Outcome of Gamma Knife Radiosurgery for Brain Cavernoma: Factors Associated with Subsequent De Novo Cavernoma Formation
2018, World NeurosurgeryCitation Excerpt :Some previous studies have suggested that the surgical removal or the radiosurgical obliteration of DVAs should not be performed.30,31,34 During the surgery, fatal venous infarction can develop if the venous drainage of the normal tissue is abruptly obstructed by an injury to the DVA.30,32-34 Therefore, most neurosurgeons make efforts to save the associated DVA during the resection of the cavernoma.30-32,34
