UASSIGNED:骨间后动脉反流(rPIA)皮瓣是修复手部和上肢缺损的绝佳工具,将主要动脉保留在手上。它的可靠性已经确立。
UNASSIGNED:回顾性分析51例rPIA皮瓣,其中49例。纳入标准是年龄,性别,病因学,缺陷的大小和位置,皮瓣尺寸,包括射孔器的数量,椎弓根长度,襟翼插图,捐助者网站覆盖,并发症,和辅助程序。
未经评估:这项研究包括44名男性和5名女性,年龄在10到73岁之间。受检者手部及上肢软组织缺损主要由外伤所致,包括18例第一网络空间的瘢痕挛缩,拇指截肢6例,先天性缺陷1例。在51个rPIA皮瓣高度中,3例因缺乏适当的椎弓根导致皮瓣失败。45例观察到筋膜皮肤模式,3例观察到肌皮肤模式。在5例不可移植的拇指截肢中,rPIA皮瓣用于动脉流入二次脚趾到拇指转移。7例有不同程度的静脉充血,2例部分坏死。在平均17个月的随访期间,患者对最终结果总体满意.
UNASSIGNED:rPIA皮瓣不仅可以用于手部和上肢的软组织覆盖,还可以作为受体动脉蒂用于二次脚趾到拇指转移。
Reverse-flow posterior interosseous artery (rPIA) flap is an excellent tool for restoration of defects in the hand and upper extremity, sparing the main arteries to the hand. Its reliability has been well established.
Fifty-one cases of rPIA flap involving 49 patients were retrospectively reviewed. The inclusion criteria were age, sex, etiology, size and location of the defect, flap size, number of perforators included, pedicle length, flap inset, donor site coverage, complications, and ancillary procedures.
This study included 44 men and 5 women, ranging in age between 10 and 73 years. The subjects had soft tissue defects of the hand and upper extremity mainly due to traumatic injuries, including scar contractures of the first web space in 18 cases, thumb amputations in 6 cases, and congenital defects in 1 case. Among the 51 rPIA flap elevations, 3 cases involved flap failure due to the absence of proper pedicle. A fasciocutaneous pattern was observed in 45 cases and a myocutaneous pattern in 3 cases. In 5 cases of unplantable thumb amputations, the rPIA flap was performed for arterial inflow to the secondary toe-to-thumb transfer. Venous congestion of varying degrees was noted in 7 cases involving partial necrosis in 2 cases. During the mean 17 months of follow-up, patients were generally satisfied with the final outcomes.
The rPIA flap can be used not only for soft tissue coverage of the hand and upper extremity but also as a recipient arterial pedicle for a secondary toe-to thumb transfer.
