Zusammenfassung: | Objective : In this study, each of the frequency of nonaneurysmal perimesencephalic subarachnoid
hemorrhage(N-PMSH), and the clinical and radiologic features, incidence and location of aneurysmal
perimesencephalic subarachnoid hemorrhage(A-PMSH), based on aneurysmal rupture and nonaneurysmal
subarachnoid hemorrhage in patients with spontaneous subarachnoid hemorrhage, are investigated for clinical
application.
Methods : Patients who showed perimesencephalic subarachnoid hemorrhage, among the 388 patients with
subarachnoid hemorrhage admitted into the our hospital from March 1994 to November 2002, were extracted ;
and their charts and angiographies were examined retrospectively. They were divided into two groups - aneurysmal
perimesencephalic subarachnoid hemorrhage group and nonaneurysmal perimesencephalic subarachnoid
hemorrhage group - and comparative analysis was conducted on the clinical patterns and radiologic characteristics
of each group.
Results : There were 22 patients(5.68%) with perimesencephalic subarachnoid hemorrhage(PMSH) among 388
patients with spontaneous subarachnoid hemorrhage. Of the 22 PMSH, 8 patients(36%) were aneurysmal
PMSH(A-PMSH), 14 patients(64%) were nonaneurysmal PMSH(N-PMSH). N-PMSH occurred not only in the
posterior circulation(5 cases), but also in the anterior circulation(3 cases). There was no difference in the CT features
of PMSH between aneurysmal and nonaneurysmal cause.
Conclusion : According to the above results, 4-vessel angiography is essential for patients with perimesencephalic
subarachnoid hemorrhage, and CTA and MRA can be used as assisting diagnosis methods. KCI Citation Count: 0 |
