RESUMO
BACKGROUND: Several benefits have been described over the years of the transradial versus femoral endovascular approach to cardiac interventions. Consequently, its use has become habitual at most centers that perform cardiac catheterizations. This paper details a right transradial approach, incorporating a variety of coils or flow diverters, which can be utilized for the endovascular treatment of different cerebral aneurysms. METHODS: From 2014 to 2016, we performed 40 endovascular procedures to treat cerebral aneurysms adopting the same right transradial approach. Five aneurysms were treated with flow diverters and 35 were treated with coils. Seven of these aneurisms were asymptomatic, whereas 33 had already ruptured. RESULTS: Satisfactory treatment was achieved in all cases through the same approach in the absence of any complications. CONCLUSIONS: A right transradial approach may be satisfactory for the endovascular treatment of different cerebral aneurysms, including aneurysms in either hemisphere. This is the largest series of cerebral aneurysms treated through a transradial approach.
RESUMO
Objetive: to determine the possibility of partial clamping and maintaining small arteries flow within a modified clip. To perform an end to side anastomosis in an artery partially clamped and demonstrate its permeability. Method: partial carotid clamping in rats and intraluminal flow measurement. End to side anastomosis suture of the vessels clamped. Histopathologic study of the brains. Results: the persistence of flow during partial clamping of the vessel. Anastomosis remained permeable after the procedures. Eas confirmed no signs of ischemia in brains fixed were reported. Conclusion: this modification in the clip allows an end to side anastomosis with partial clamping of the recipient vessel, keeping the flow within in, in small vessels.
