Diagnosis of spina bifida requires the systematic examination of each neural arch from the clerical to the sacral region both transversely and longitudinally .

结果骶前区静脉由骶前静脉丛和骶椎椎体静脉组成，有广泛的侧支循环，骶骨C区骨折及严重的B区骨折易损伤骶前静脉丛。

Results The anterior sacral veins consist of the venous plexus of presacral region and conus veins of sacral vertebrae .

CT所见：（1）骶前区单发分叶状或结节状肿块，或多发性肿块。

The CT scanning findings included : ( 1 ) Mono-segmented or nodular masses in the sacre-anterior region , or multiple masses .

目的：研究骶前区静脉丛（Venousplexusofpresacralregion，VPPSR）的解剖学特点，为骶前区静脉破裂大出血的防治提供解剖学基础。

To provide anatomic basis for precaution and treatment of the massive hemorrhage of venous plexus of presacral region ( VPPSR ) in Mile 's operation .

骶前区静脉丛的解剖学特点及临床意义

Anatomic characteristics and clinical significance of the venous plexus of presacral region

藏毛窦是一种骶尾部区常见的的慢性疾病。

Pilonidal sinus is a common chronic disease of the sacrococcygeal region .

目的：为直肠癌根治术引起骶前区静脉破裂大出血的防治提供形态学基础。

Objective : To supply the anatomical data for the massive hemorrhage during the surgery of rectal carcinoma .

冷脓肿分布于骶前区、髂窝区和/或臀肌区。

The cold abscess were distributed at the presacral , unilateral iliac fossa and / or the gluteal region .

腰背部包括腰骶中线区、骶髂关节区域、髂部后上棘、髂骨嵴以上范围和骶尾部。

The midline lumbosacral area , the sacroiliac joint region , the posterosuperior iliac spine , the high iliac crest area , and the low midline sacrococcygeal region are all included in the back .

两种平卧承托位头枕区、肩胛区及骶尾区界面压力比较，均有统计学意义（均P<0.05）。

In terms of interface pressures of occipital , scapular , and sacrococcygeal region of patients , there were statistical significance between the two backlying support ⅰ and ⅱ positions ( P < 0.05 ) .

由于骶前区静脉的解剖特点，造成远侧骶前区静脉的最大静水压可以达到17~23cmH2O，可在短时间内丢失大量静脉血。

Determined by the anatomic features of the presacral region , the hydrostatic pressure of the distal presacral veins can reach as high as 17 to 23 cm H_2O , approximately double or triple that of the normal inferior vena cava .

[结果]测得的压力均集中在头枕区、肩胛区和骶尾区，且自动交替承托时，压力点有明显移动，压力值改变，压力值改变最大达10.87kPa；

Result : The detected pressures of patients were centralized on occipital , scapular , and sacrococcygeal region . Moreover , pressure point of patients moved obviously as the support points changed automatically , and pressure value was also changed which reached 10.87 kPa .

结果182例患者骶髂关节区（SIJ）阳性热图98.3%，X线SIJ炎≥Ⅱ级者73.1%。

Results The positive rate of SIJ infrared thermography in 182 patients was 98.3 % , while X-ray was 73.1 % .

方法：对26具（52侧）成人尸体进行骶前孔区血管、神经走行特点的观察，对具有临床意义的数据进行解剖学测量。

Methods : The blood vessels , sacral nerve of presacral region and piriformis were observed and measured on 26 adult cadaveric specimens .

胎儿及新生儿骶椎椎体软骨区的血管

The blood vessels of sacral vertebral cartilages in fetuses and newborns

结论：后路骶神经管扩大减压术是相对安全的，但应避免损伤骶前孔区的血管；

Conclusions : Posterior approach enlargement of sacral nerve canal is relative safty , and should avoid injury the presacral vessels .

方法取60具骶骨干标本及26具完整骨盆标本，测量S1棘突与S1后孔间位置关系、骶前区血管、骶神经及梨状肌之间关系。

Methods The blood vessels , sacral nerve of presacral region and piriformis , S1 spinous process and S1 posterior sacral foramina were observed and measured on 26 adult cadaveric specimens and 60 adult sacrals .
