The Classification And Clinical Significance Of The Superficial Vein Group Of The Cortical Motor Area

Objective :The brain's venous system can be divided into superficial veins, deepveins, posterior fossa veins.The precentral gyrus is the primary motor area .Thefunctional injury of the motor area can cause paralysis of limbs,epilepsy and otherserious complications, affecting patients' quality of life.The superficial venous returnis an important part of the anatomy and function of the motor area.The injury of theintensive superficial venous system here could easily lead to paralysis, coma, cerebraledema, hemorrhagic infarction,and so on,aggravating the disease and affecting theprognosis.The great variation of superficial vein here and the lack of research makeclinicians unfamiliar with them and lead to the unnecessary injury.Based on theanalysis of clinical data,the paper explores the distribution and the clinicalsignificance of the superficial veins of the motor area of normal adult brain.Methods:We adopt retrospective analysis with 43 normal adults' digital substactionangiography(DSA) of the First Affiliated Hospital of Nanjing Medical University. Weobserved and measured the distribution and morphology of the superficial and relatedbackflow veins of the motor areas of the brain.Results: The central sulcus vein and the previous central sulcus vein are the mainsuperficial veins of the motor area,but not all are well developed.By observation,absence of the central sulcus venous rate is 11.6%.Trolard vein,also known asanastomosis veins,often involves in veins of motor areas.Vein group of motor area can be divided into:parallel, human shaped, more dry,alone type.Conclusions: There are great variations in the superficial vein of the cerebral motorarea. Preoperative identification of the anatomy of the vein and rationally designedsurgical approaches can avoid injury during operation and complications.
