肾动脉的段动脉支创伤性血栓形成与创伤性肾动脉分支破裂不同。前者肾实质完整,无肾周及肾内出血;后者常伴有肾裂开,肾之一极或某一段破裂,肾实质大量缺损并出血,需要手术处理。肾外伤时,传统的IVP检查和非手术治疗不能诊断段动段支创伤性血栓形成。随着CT、同位素肾造影和动脉造影广泛应用于肾损伤的估价,该型损伤已常获确诊,但对其应否作积极的手术治疗则不清楚。作者在1959～1985年诊治的1668例肾外伤中见到43例为肾蒂损伤,其中9例段动脉血栓形成(7男 Traumatic segmental arteries of the renal artery traumatic thrombosis and traumatic renal artery rupture different branches. The former renal parenchyma integrity, no perirenal and intrarenal hemorrhage; the latter is often accompanied by open renal rupture, one of the kidney or some rupture, a large number of renal parenchymal defects and bleeding, the need for surgical treatment. Traumatic renal injury, the traditional IVP examination and non-surgical treatment can not diagnose the dynamic segment of traumatic thrombosis. With CT, isotope nephrophy and arteriography are widely used in the valuation of renal injury, this type of injury has been often diagnosed, but its whether or not active surgical treatment is unclear. Of the 1668 renal injuries diagnosed and treated between 1959 and 1985, 43 were found to have renal pedicle injury, of which 9 were segment arterial thrombosis (7 male
