with angiographic findings

Aim: Aim of this study was to analyze the distribution of spontaneous intradural cerebral artery dissection in angiographically
with the symptomatology of admitted patients to our hospital.
Materials & Methods: We analyzed retrospectively collected data of the stroke patients’ with 4-vessels angiogram in our
institute from January 2013 to June 2014. Out of 164 of cerebral dissections in angiographic pattern, we found only 16 patients
of intradural dissecting aneurysms that were included in this study. The male-female ratio was 37.5:62.5 and the mean age was
47.56±13.19 years. According to the angiographic finding depicting the location of the dissection plane in the arterial wall,
we categorized to steno-occlusive, aneurysmal and combined (steno-occlusive and aneurysmal) pattern. In each dissection
pattern, we evaluated presenting symptoms and presence of subarachnoid hemorrhage (SAH), infarction and intracerebral
hemorrhage (ICH) or combined.
Results: The most common symptomatic presentation was headache (75%), followed by neck pain (50%), motor weakness of
limb(s) (43.8%) and loss of consciousness (LOC) (37.5%). The most common angiographic pattern was aneurysmal patterns
(68.75%) followed by steno-occlusive (18.75%) and combined (12.5%) patterns. Aneurysmal pattern was most frequently
related to SAH (7/11, 63.63%) in contrast to steno-occlusive pattern was only related to infarction (3/3, 100 %). The most
frequent dissections were in the intradural vertebral arteries (IV) and posterior cerebral artery (PCA), presented with SAH
80% (4/5) and 33.33 % (1/3), respectively. Infarction was common abnormality in patients with the intradural carotid arteries
(IC) 33.33% (1/3), superior cerebellar artery (SCA) 33.33% (1/3) and basilar artery (BA) 33.33% (1/3) each whereas ICH was
common abnormality in patients with the posterior inferior cerebellar artery (PICA) 50% (1/2).
Conclusion: The most common symptomatology of intradural cerebral artery dissection are headache and neck pain followed
by motor weakness of limbs and LOC. SAH with aneurysmal pattern, in the posterior circulation, especially in the IV is the
most frequent diagnosis which requires combined analysis of angiographic pattern and clinical presentations of stroke.
