BACKGROUND: In many clinical trials endovascular procedures are suggested as the treatment of choice for aneurysmal Subarachnoid Hemorrhage (aSAH) whenever possible. However, in clinical practice this management is often controversial. The aim of this study was to analyze factors involved in this decision.
METHODS: Our study included 317 consecutive cases of aSAH between 2010 and 2016, assessing clinical and neuroradiological features to evaluate their role in this choice.
RESULTS: In our series coiling was preferred in 119 (37.6%) patients, while 198 (62.4%) were treated surgically. On univariate analysis location of aneurysms (P<0.001), GCS score on admission (P=0.105), degree of midline shift (P=0.015), Fisher’ score (P=0.002) and presence of vessels in the aneurysmal neck (P=0.071) proved the most relevant factors in the choice. Also, multivariate analysis confirmed the location and Fisher’ grade as influential factors. Conversely, other radiological parameters, such as morphology, aspect and dome-neck ratio, presence of pre-operative vasospasm or hydrocephalus were not associated with this decision.
CONCLUSIONS: The decision process in aSAH requires a multidisciplinary team, to singularly evaluate each patient. We found that the location of aneurysms in vertebro-basilar circulation, PcomA and ICA, greater GCS score, absence of vessels in the aneurysmal neck, lower midline shift and Fisher’ score are factors influencing in choosing coiling. Conversely, morphology, Aspect and Dome-Neck ratio proved not relevant to this decision, due to technological improvement and increasing skills in the endovascular treatment.
