A patient was defined as a smoker if he or she was a current smoker in the last 12 months. Arterial hypertension was defined in 2 ways: (1) if the patient was being treated with antihypertensive drugs or his or her medical record gave such a diagnosis, (2) 2 blood pressure recordings with both a systolic blood pressure >160 mm Hg and a diastolic blood pressure >95 mm Hg. We used the following definitions for vascular risk factors.
There is no standardized selection criteria for performing conventional angiography in our hospital, but angiography is not usually performed in patients who have a known cardiac source of embolism, are elderly, or would not give consent. All patients had been diagnosed by MRI axial T2 (repetition time 2500 ms echo time 80 ms), axial T1, and gadolinium-enhanced T1-weighted scans were performed in the horizontal plane at 3-mm intervals from the medulla to the midbrain. Of these patients, we selected 31 patients in whom (1) MRI showed an appropriate cerebellar lesion and (2) transfemoral conventional angiography was performed. The result that large-artery disease, in which nonterritorial infarcts are more common than territorial infarcts, is more prevalent than in situ branch artery disease or small-artery disease, suggest that even a small cerebellar infarct can be a clue to the presence of large-artery disease.įrom January 1998 through April 1999 we prospectively collected data from patients with cerebellar infarction at Kyungpook National University Hospital. No angiographic disease with hypertension was associated with small-sized cerebellar infarcts within the SCA, anterior inferior cerebellar artery, or SCA cerebellum.Ĭonclusions-Our study indicates that the topographic heterogeneity of cerebellar infarcts are correlated with diverse angiographic findings. The in situ branch artery disease was correlated with the PICA cerebellum lesions, which were territorial or nonterritorial infarct. The subclavian artery or brachiocephalic trunk lesion was associated with small cerebellar infarcts. The intracranial occlusive disease without V1 lesion was usually correlated with small cerebellar lesions in PICA and superior cerebellar artery (SCA) cerebellum. The V1 lesions with coexistent occlusive lesions of the intracranial vertebral and basilar arteries were correlated with cerebellar infarcts, which had no predilection for certain cerebellar territory. The proximal segment (V1) lesions of vertebral artery were the most common angiographic features in patients with large-artery disease in which stroke most commonly involved the posterior inferior cerebellar artery (PICA) cerebellum. Results-The vascular lesions seen on angiograms were subdivided into 3 groups: large-artery disease (n=22), in situ branch artery disease (n=6), and no angiographic disease with hypertension (n=3). We attempted to correlate MRI lesions with the vascular lesions shown in the angiograms. We analyzed the risk factors, clinical findings, imaging study, and angiography results. Methods-The subjects included 31 patients with cerebellar infarcts who underwent both MRI and conventional cerebral angiography. The aim of this study was to correlate the MRI lesions with the vascular lesions seen on conventional cerebral angiography in cerebellar infarction.
