Ruptured irregularly shaped aneurysms: pseudoaneurysm formation in a thrombus located at the rupture site.
The authors describe the clinical, radiological, and pathological findings of ruptured cerebral aneurysms with irregular configurations. ⋯ Ruptured irregularly shaped aneurysms may be accompanied by fragile pseudoaneurysm-like cavities located at the rupture point. Because these aneurysms have a high risk of repeated rupture during an endovascular procedure, advancing microinstruments to the weaker portion of the aneurysm should be avoided.
