No experimental studies have substantiated the claim that fasciocutaneous flaps are superior to skin flaps. Using fasciocutaneous flaps designed in the pig, both flap survival and blood flow were assessed. The forelimb and hindlimb fasciocutaneous flaps survived to 8.2 +/- 0.3 cm and 7.9 +/- 0.3 cm, respectively, compared with 7.3 +/- 0.3 cm and 6.7 +/- 0.3 cm for the comparable cutaneous flaps, a statistically significant finding (p less than 0.01). Random fasciocutaneous flaps survive 12 to 18 percent longer than skin flaps. Using the radioactive microsphere technique, blood flow was measured after flap elevation, and flap survival was estimated using fluorescein. Again, a significant difference in flap survival was found, but there was no significant difference in measured blood flow. This can be explained by the relatively large interval between blood flow measurements (2 cm) compared with the observed difference in survival length (1.0 +/- 0.3 cm).
尚无实验研究证实筋膜皮瓣优于皮瓣这一说法。利用在猪身上设计的筋膜皮瓣，对皮瓣存活情况和血流情况进行了评估。前肢和后肢筋膜皮瓣分别存活至8.2±0.3厘米和7.9±0.3厘米，相比之下，同类皮瓣分别为7.3±0.3厘米和6.7±0.3厘米，这是一个具有统计学意义的发现（p小于0.01）。随意型筋膜皮瓣的存活时间比皮瓣长12%至18%。采用放射性微球技术，在掀起皮瓣后测量血流，并使用荧光素估计皮瓣存活情况。同样，在皮瓣存活方面发现了显著差异，但在测量的血流方面没有显著差异。这可以通过与观察到的存活长度差异（1.0±0.3厘米）相比，血流测量之间的间隔相对较大（2厘米）来解释。
