ABSTRACT
Objective To evaluate the size,aspect ratio and configuration in ruptured aneurysms. Methods Three-dimensional CT angiogram of 61 confirmed ruptured saccular aneurysms were analyzed.The maximum diameter and aspect ratio were measured,and the configuration of the aneurysms were observed. Results The average maximum diameter was 8.54 mm,and 78.8% of the aneurysms were less than 10 mm in maximum diameter.The average aspect ratio was 2.15,and more than 65% of the aneurysms had an aspect ratio over 1.6.45.9% of the aneurysms harbored a bleb or were multi-lobular in shape. Conclusion Aneurysms less than 10 mm in maximum diameter are also easy to rupture.More than 60% of the ruptured aneurysms had an aspect ratio over 1.6.Bleb and multi-lobular change are common in ruptured aneurysms.
ABSTRACT
The potential of hypothermia in reducing neuronal damage has been demonstrated in several animal models of focal cerebral ischemia. The feasibility and safety of this technique for acute stroke has been only examined in one study, describing a total of 25 patients. We analyzed the data from 50 consecutive patients with acute stroke treated with moderate hypothermia in neurocritical care units of 4 university clinics to evaluate the feasibility and safety of moderate hypothermia.
