In 1981 we received the Gore-Tex PTFE vascular prostheses, 12 mm in diameter, in order to test their value. Experimental studies were carried out on 6 piglets, in which 5 cm long sections of the prostheses under study were grafted into surgical defects of the thoracic aorta. The dissections were made 1, 3, 6 months after grafting, each time detailed pathomorphological studies were carried out. The results show that PTFE prostheses, grafted into a piglet thoracic aorta was surrounded by fibrinous connective tissue. The tissue on the outside of the prostheses differs in histological structure from that inside. After 6 months it was found that the prosthesis has inside a thin layer of fibrinous connective tissue, connected to the prostheses wall; the layer did not constrict the internal diameter. The Gore-Tex prostheses fulfill biological requirements on vascular prostheses after their grafting into operational defects of the aorta.
1981年，我们收到了直径为12毫米的戈尔特斯聚四氟乙烯血管假体，以测试其价值。对6只仔猪进行了实验研究，将所研究的5厘米长的假体节段移植到胸主动脉的手术缺损处。在移植后1个月、3个月、6个月进行解剖，每次都进行详细的病理形态学研究。结果表明，移植到仔猪胸主动脉的聚四氟乙烯假体被纤维结缔组织包围。假体外部的组织在组织结构上与内部不同。6个月后发现，假体内部有一层薄薄的纤维结缔组织，与假体壁相连；该层并未收缩内径。戈尔特斯假体在移植到主动脉手术缺损处后满足了对血管假体的生物学要求。
