To analyze the impact of hematoma location and vascular territory on the clinical symptoms and signs, neuroimaging findings, and clinical prognosis of striatocapsular hemorrhage.The data of 181 cases of striatocapsular hemorrhage, 124 males and 57 females, aged 28 - 89, including medical history, symptoms, and signs were analyzed. On the basis of hematoma locations and arterial territories, the striatocapsular hemorrhage was divided into six types: anterior type (with the blood supply from Heubner's artery), middle type (with the blood supply from medial lenticulostriate artery), posteromedial type (with the blood supply from anterior choroidal artery), posterolateral type (with the blood supply from posteromedial branches of lateral lenticulostriate artery), lateral type (with the blood supply from the most of lateral branches of lenticulostriate artery), and massive type (with the hematoma occupying the whole or greater part of striatocapsular region). The short-term clinical outcome and prognosis were evaluated by Modified Rankin Scale (MRS). The relationship between the type and outcome was analyzed.There were 22 cases of anterior type, accounting for 12.15%, of which 68.18% showed an excellent outcome (MRS = 0 - 2) and only 1 case died. There were 12 cases of middle type, accounting for 6.63%, of which 6 cases (50%) showed a poor outcome (MRS = 5) but without dead case. There were 19 cases of posteromedial type (10.50%), of which 52.63% had excellent outcome (MRS = 0 - 2) without dead case. There were 19 cases of posterolateral type (18.78%), of which 76.47% were with poor outcome (MRS = 5) and 17.65% died. Accounting for 39.23%, lateral type was the most common condition, of which 38.03% patients had a poor outcome (MRS = 5) and 8.45% cases died. The incidence rate of massive type was also high (12.71%), of which 47.82% showed a poor outcome (MRS = 5) and 47.83% cases died.Hematoma location and vascular territory are the determinating factors of prognosis of striatocapsular hemorrhage. The six-type classification system provides a simple and reliable means to predict the clinical outcomes and to guide therapeutic options of striatocapsular hemorrhage. |
