Management of Arteriovenous Malformations Related to Spetzler-Martin Grading System

Abstract: Advanced technology and improved understanding of the natural history of arteriovenous malformations (AVMs) led to the reconsideration of the management of these lesions, which once comprised purely microsurgical removal. A multidisciplinary approach for both the evaluation and treatment of AVMs has gained acceptance within the past few decades. Treatment options for AVMs include surgical resection, embolization, or stereotactic radiosurgery, or any combination of these procedures. The risk of a chosen managem… Show more

“…In order to evaluate independent factors affecting outcome, a binary logistic regression model was constructed, using the Wald method (first entering variables into the model and then using stepwise backward elimination). Stepwise logistic regression was used in multivariate analysis to identify independent predictors of dichotomized outcomes (favorable vs. poor, defined as GOS 1-2 vs. 3-5, or m RS 0-2 vs. [3][4][5][6]. The association between the timing of surgery and duration of intensive care unit (ICU) treatment was studied using Spearman's non-parametric correlation.…”

“…The definitive treatment of cerebral arteriovenous malformations (AVMs) remains complete microsurgical removal by an experienced surgeon [4,9,12,21,23,24,39,47,51,52]. However, it is considered to be one of the most difficult neurosurgical tasks [1,52].…”

“…Although hemorrhage from an AVM can be disabling or deadly, the course in many non-operated high-grade AVMs (Spetzler Martin grades 4 and 5) can be quite benign, if compared with their intervention risk. This may justify conservative treatment in high-grade/high-risk AVM s. [17,18] As each of these procedures has its own associated complications and limitations, choosing the modality of choice for treatment presents a significant dilemma for every physician. In addition, the numerous variables affecting the results and uncertainties surrounding the natural history have also made treatment selection more difficult.…”

“…From the results of our study, the definite lesion location, size, arterial feeder, and venous drainage all had good specificity in diagnosis. This means that the basic Spetzler-Martin grading of AVM ( 39 ), diagnosed by the nidus and venous drainage, and Borden-Shucart grading system of dAVF ( 40 ), mainly identified by the drainage vein, can be mostly diagnosed on 4D-TRAK MRA. Thus, with the aid of 4D-TRAK MRA, sufficient information for clinical therapeutic decision-making and planning can be obtained ( 30 , 37 , 41 - 43 ).…”
