Covered stents in neural interventional therapy / 中国组织工程研究

BACKGROUND: With the development of neural interventional therapy, the application of covered stents in neural intervention is becoming a topic of general interest.OBJECTIVE: To introduce the structure of stent-graft, and to summary the application of covered stents in clinical treatment of the neural interventional therapy and the shortage of covered stents.RETRIEVAL STRATEGY:The relevant articled were searched for in Pubmed database by researcher of this article with the key words of "stent graft, covered stents, cerebrovascular disease" in English, and with the key words of "covered stent, cerebrovascular disease" in Chinese in VIP database. 223 English and 196 Chinese articles were selected and reviewed primarily. Inclusive criteria: Articles having a close relation with the application of covered stents in neural intervention, especially in cerebrovascular disease, and the latest articles or articles published in authority journals in the same field were chosen. Exclusive criteria: articles with repetitive studies were excluded.LITERATURE EVALUATION: 223 English and 196 Chinese articles were primarily checked by reading titles and abstracts. Among the 31 collected articles, 4 are reviews, 3 are experimental studies and others are clinical studies.DATA SYNTHESIS: Covered stents show special advantages in neural interventional therapy and become a hot spot in present study. There are individual case reports or small group case reports on the application of covered stents in hemorrhagic cerebrovascular disease. It is reported that the covered stent effectively occludes aneurysm, dissecting aneurysm and arteriovenous fistula, keeps patency of the parent artery. The covered stent isolates ulcerated plaque via physical barriers, avoids the abscission of embolus, which can further reduce the development of embolism in percutaneous carotid artery stenting. After releasing covered stents, polytetrafluoroethylene makes the disepiment smooth. Its good biocompatibility reduces thrombosis, and then decreases the incidence of restenosis. Covered stents in vessel for cerebrovascular disease have achieved good effects, but there are some problems in clinic as follows. ①The main shortage of covered stents is to occlude small branch vessels. ②Thrombosis and restenosis occur after covered stenting. ③Covered stents increase the volume of the stent, reduce the compliance and flexibility of the stents, and increase the pushing difficulty and vascular injury. ④Covered stents cannot be used in vessels of less than 4 mm.CONCLUSION: Covered stents for intracranial ischemic and hemorrhagic diseases shows significant outcomes, but there are disadvantages. With the clarification of the related theories and the improvement of new material technology, there will be a brighter future of the application of covered stents for treatment of cerebrovascular diseases.

Study on the methods for establishing virtual three-dimensional models of cerebral arteries with the three-dimensional moulding software / 生物医学工程学杂志

This study was conducted to establish the methods of virtual three-dimensional cerebral arteries models by use of three-dimensional moulding software. The virtual models of the cerebral arteries were established using the three-dimensional moulding software of 3D Studio MAX R3 with 46 cases of normal cerebral DSA image as the original. The results showed there was similarity in appearance between the virtual cerebral arteries and DSA image. This is of benefit to understanding the vascular three-dimensional spatial relation in visual sense. Several models of different variant anatomy could be easily established on the copy files of the virtual cerebral arteries model. The virtual model could help learners to create and increase the three-dimensional space concept of arteries and aneurysms in clinical teaching. The results indicated that the virtual three-dimensional cerebral arteries models could display the three-dimensional spatial relation of the cerebral arterial system distinctly, and could serve as a morphologic foundation in the researches on vascular disease.
