[Doppler scanning in aneurysm surgery].
Subarachnoid hemorrhage still represents important medical problem, from both, ineffective prevention and high morbidity and mortality rate of the condition. On the other hand, majority of patients who survive initial hemorrhage and successful clipping of their aneurysm can live without major medical restrictions. Apart from surviving the initial attack the most important condition is properly clipped aneurysm. Doppler scanning control allows precise placement of the clip on the neck of an aneurysm. Since January 1997 through December 1999 the authors have surgically treated 204 aneurysms in 181 patient. In 40 surgeries the Doppler scanning was employed after the aneurysm complex was dissected free. Using 20 MHz PW Doppler probe the flow within the aneurysm and in the involved arteries was measured (usual depth 1.5 mm, range 1-2.5 mm). After the clipping the flow was evaluated again, to ensure proper exclusion of an aneurysm and good flow in involved arteries. The authors consider the Doppler scanning to be important technical aid in aneurysm surgery, especially in anatomically complex situations.
