Clinical Characteristics of Ruptured Aneurysms in Jilin Province of Northeastern China: An Analysis of 694 Cases

摘要

Objective: To investigate the clinical characteristics ofruptured aneurysms in Jilin ProvinceDesign: Retrospective analyses of prospectively recordeddataSetting: Department of Neurosurgery, The First Hospital ofJilin University, Jilin Province, ChinaSubject: Data collected from 694 cases of ruptured aneurysmsin 2014Intervention: Each patient’s basic information, aneurysmcharacteristics and whether multiple aneurysms had occurredwere recorded. A summary of the date and time of theincidence of aneurysmal subarachnoid hemorrhage (aSAH)was noted.Main outcome measure: This study recorded thecharacteristics of ruptured aneurysms in Jilin Province andmade comparisons with the established tendencies in otherstudies.Result: Among the 694 cases, there were high incidence ratesof aSAH between March and May and between Septemberand November, as well as between 5 AM and 8 AM. Thecondition was more common in females than in males. Thediameters of 74.2% of the aneurysms were between 3 and 10mm. Anterior communicating artery aneurysms (AcoAs)were the most common (accounting for 37.8% of the anteriorcirculation aneurysms), followed by posterior communicatingartery aneurysms (PcoAs), accounting for 27.6% of theanterior circulation aneurysms. Multiple aneurysmsaccounted for 25.8% of all of the aneurysms. Mirror aneurysmscomprised 6% of all of the aneurysms and 23.4% of themultiple aneurysms, which mainly consisted of bilateralPcoAs and bilateral middle cerebral artery aneurysms(MCAs). The above results were consistent with the tendenciesof other studies, including the seasonal, daytime, age andgender-female predispositions.Conclusion: Although this study demonstrates highconsistency with other studies, the results are onlyrepresentative of Jilin Province in China, which indirectly cancontribute to the understanding of aneurysm rupture risks.
