Objective Clarify the safety and efficacy of the endovascular treatment of distal anterior cerebral artery (DACA) aneurysms, reporting outcomes of the aneurysms coiled in our service were compared with series of microsurgical treatment. The impact of embolization on ruptured or unruptured aneurysms remains controversial according to the current data, considering aneurysm from this topography should be aggressively treated due to their high incidence of rupture, currently there is a tend to prefer endovascular treatment. Methods We conducted a retrospective cohort study with 1092 patients admitted with cerebral aneurysm from October 2005 to March 2015 in our service. There were 31 cases of DACA aneurysms treated with the endovascular technique. These were compared with same topography aneurysms underwent to clipping. Results A total of 21 (67%) of 31 cases presented with ruptured aneurysms, 13 (59%) suffered clinical or radiological vasospasms, with modified Rankin Scale (mRS) scores of 3–5 in 7 patients (31%), and 4 deaths (mRS 6), reaching 92% of occlusion at one year. Conclusion Endovascular approach is associated with high angiographic occlusion rates and security.

Objective Compare 30 days mortality of patients harboring acute subdural hematomas in two series, one treated only by wide aspiration of hematoma and other with aspiration followed by decompressive craniectomy. Methods Comparing retrospectively two series of ASD with and without DC. Involved 81 TBI patients with acute subdural hematoma and GCS ≤ 8 (Jan 2000 to Nov 2014) arranged into two groups. Group 1 - 58 cases underwent to DC. Group 2 - 23 patients underwent only hematoma aspiration. Results Group 1 showed 44.8% mortality directly due to brain lesion within 30 days. The most frequent associated lesion were contusion in 37.2%. Group 2 the mortality within 30 days was 47.8%. The majority of deaths (82%) resulted from uncontrollable brain swelling, midline shift was present in 94.7% of patients. Conclusion High admission GCS and age less than 50 remain better outcome predictor in 30 days survival for patients undergoing surgery of traumatic ASDH.
