尺动脉变异有较多文献报道【1~6】,但作者在前臂血管神经肌腱探查修复手术中,发现1例尺动脉在前臂中下段走行变异的特殊病例。现报道如下。患者,男,45岁,因左前臂玻璃割伤就诊。急诊行左前臂血管神经肌腱探查修复术。术中见左前臂尺侧中下1/3平面一长约8 cm的横行皮肤挫裂伤口,伤口内见:尺侧腕屈肌腱断裂,环小指指深、浅屈肌腱部分断裂,尺神经断裂,尺神经周围无尺动脉走行(图1)。探查见:指浅屈肌与桡侧腕屈肌之间有一大动脉走行,直径跟尺动脉直径相近,有两条伴行静脉伴行于动脉两侧,该动脉于前臂下1/3走行于指浅屈肌腱及掌
There are many reports of ulnar artery variability in the literature [1 ~ 6], but the author found in the forearm vascular nerve tendon exploration and repair surgery, found in 1 case of ulnar artery in the lower extremity of the special case of walking variation. Report as follows now. The patient, male, 45 years old, was diagnosed with a left forearm glass cut. Emergency line left forearm vascular neurovascular exploration repair. Surgery, see the lower left forearm ulnar 1/3 plane a length of about 8 cm of the transverse skin laceration wound, see the wound see: ulnar flexor tendon rupture, ring little finger deep, shallow flexor tendon partial rupture, ulnar nerve rupture , Ulnar nerve around the ulnar artery walk (Figure 1). Exploration to see: refers to the superficial flexor and flexor carpi radialis between a large artery run, diameter and the diameter of the ulnar artery, there are two accompanying veins accompanied by the artery on both sides of the artery in the forearm, Superficial flexor tendon and palm
