Background: The aim of this study was to define the sonographic evaluation and morphometric measurements of the suprascapular notch.
Methods The suprascapular notch was evaluated by ultrasound on both sides in 50 volunteers (25 males, 25 females). By means of ultrasound,
the notch width, the notch depth and the distance between the skin and the notch base (skin–notch base interval) were measured
and imaging of the superior transverse scapular ligament was attempted. Furthermore, imaging of the suprascapular artery and
vein was performed by Doppler ultrasound.
Results On the measurements performed, the notch was found to be deeper in men than in women on both the right (P = 0.022) and the left (P = 0.011) sides. Taking all volunteers into account without grouping sex, no differences were detected between the two sides
with respect to the measurements of the notch width, notch depth and distance between the skin and the notch base. The superior
transverse scapular ligament was demonstrated in 48 (96%) of 50 volunteers. On color Doppler ultrasound, the artery–vein complex
was visualized in a total of 43 (86%) volunteers.
Conclusions Suprascapular notch measurements and the visualization of the anatomical neighborhood, which may be beneficial for the suprascapular
nerve blockade procedure, can be successfully performed by the use of high-frequency ultrasound imaging. 相似文献

The anatomy of the suprascapular nerve is important to surgeons when focal nerve lesions necessitate surgical repair. Recent experience with a patient who had a complete suprascapular nerve lesion in the retroclavicular region (combined with axillary and musculocutaneous nerve lesions) is presented to illustrate that successful direct nerve repair is possible despite resection of a neuroma. Specifically, we found that neurolysis and mobilization of the suprascapular nerve and release of the superior transverse scapular ligament provided the necessary nerve length to achieve direct nerve repair after the neuroma was removed. A combined supraclavicular and infraclavicular approach to the suprascapular nerve provided excellent visualization, especially in the retroclavicular region. Postoperatively, the patient recovered complete shoulder abduction and external rotation with the direct repair, an outcome uncommonly achieved with interpositional grafting. Based on our operative experience, we set out to quantify the length that the suprascapular nerve could be mobilized with neurolysis. Mobilization of the nerve and release of the superior transverse scapular ligament generated an average of 1.6 cm and 0.7 cm of extra nerve length respectively, totaling 2.3 cm of additional usable nerve length overall. The ability to expose the suprascapular nerve in the retroclavicular/infraclavicular region and to mobilize the suprascapular nerve for possible direct repair has not been previously emphasized and is clinically important. This surgical approach and technique permits direct nerve repair after resection of a focal neuroma in the retroclavicular or infraclavicular region, thus avoiding interpositional grafting, and improving outcomes. 相似文献

Suprascapular nerve entrapment caused by the superior transverse scapular ligament (STSL) causes pain, and limitation of motion in the shoulder. To relieve these symptoms, suprascapular nerve decompression is performed through the resection of STSL. To describe and classify the topographic anatomy of the suprascapular notch, 103 cadaveric shoulders were dissected. The mean length and width of STSLs were 11.2 and 3.4 mm, respectively. The bony bridges replacing STSL in four shoulders were 8.2 mm long and 3.5 mm wide on average. The suprascapular nerve always ran through the notch under the STSL. All shoulders had a single suprascapular artery, while multiple suprascapular veins appeared in 21.3%. The arrangement of the suprascapular vessels was classified into three types: in Type I (59.4%), all suprascapular vessels ran over the STSL; in Type II (29.7%), the vessels ran over and under the STSL simultaneously; in Type III (10.9%), all vessels ran under the STSL. In 48.9% of cadavers, these types were bilaterally matched. The omohyoid muscle originated distantly from the STSL in 38.0%, was adjacent to it in 44.0%, and was partially over the STSL in 18.0%. The number of suprascapular vessels running under the STSL was positively correlated with the size of the STSL and the middle diameter of the suprascapular notch. Age was inversely correlated with the length of STSL. The STSL was wider in males than in females. This study provides details of the structural variations in the region of the suprascapular notch. 相似文献

The suprascapular nerve can be compressed by the inferior transverse scapular ligament (ITSL), also known as the spinoglenoid ligament, and this entrapment results in dysfunction of the external rotation of the upper arm owing to isolated weakness of the infraspinatus muscle. The morphology of the ITSL has not been adequately characterized. The aim of this study was to clarify the morphological characteristics of the ITSL. In total, 110 shoulders from 72 cadavers were dissected in this study. The ITSL was present in 73 (66.4%) of the 110 specimens, and comprised membrane in 40 (36.4%), ligament in 25 (22.7%), and both membrane and ligament in eight (7.3%). This structure could be classified into three types on the basis of its shape: band‐like (33.6%, type I), triangular (15.5%, type II), or irregular (17.3%, type III). In the spinoglenoid notch, the suprascapular nerve was always close to the lateral margin of the scapular spine. The length of the ligament between its origin and insertion sites ranged from 8.7 to 23.4 mm at its superior margin and from 8.9 to 17.5 mm at its inferior margin. The ligament width and thickness at its midportion ranged from 1.6 to 10.0 mm and from 0.1 to 1.2 mm, respectively. The results of this study improve understanding of the ITSL and will be helpful for successful diagnoses and treatments for selective suprascapular nerve entrapment. Clin.

目的 探讨经食管超声心动图(TEE)在微创心脏外科直视手术(MIDCS)中的应用价值。方法 回顾性研究。纳入淮北矿工总医院2018年7月-2019年11月接受MIDCS的患者20例,其中男8例、女12例,年龄(57.5±10.2)岁。术前诊断:先天性心脏病6例,瓣膜病13例,左心房黏液瘤1例。20例患者术前均常规行经胸超声心动图(TTE)检查,术中均采用TEE监测。麻醉诱导后TEE检查修正诊断,指导建立体外循环,开放升主动脉前指导心腔排气;术中,于病变处理完成后即时TEE监测心内血流、瓣膜及心功能情况;于手术操作完成、心脏复跳后,应用TEE评价手术疗效,以无残余分流、瓣周漏、瓣膜关闭不全及左心室射血分数(LVEF)>50%为治愈。结果 经术中引导,20例患者均准确置于引流管、排空心脏。经TEE检查修正诊断5例:1例下腔型房间隔缺损术中发现另有一小的房间隔缺损,术中一并予以修补;1例房间隔缺损者房水平仅有微量分流,无需处理;2例三尖瓣关闭不全患者合并三尖瓣前叶裂,均行瓣叶修复后再予三尖瓣成形术;另1例则排除了左心房血栓。病变处理完成后,因术中TEE即时评估疗效不满意而更改手术方式2例:1例三尖瓣成形术后瓣膜关闭不满意者改行三尖瓣置换术,1例室间隔修补术后残余分流者改行胸骨正中切口继续修补。另有2例术毕即时通过TEE发现低心排血综合征,行主动脉内球囊反搏术。全组未见食管损伤和相关并发症,无手术死亡病例。术后均无残余分流、瓣周漏及少量以上反流,黏液瘤完全切除;术后患者症状明显缓解,LVEF为54%~69%(61.40%±3.65%),与术前[44%~67%(58.70%±5.19%)]比较差异有统计学意义(t=2.896, P<0.05)。本组患者治愈率100%。结论 术中TEE监测应用于MIDCS中,在补充修正诊断、引导体外循环建立、手术操作完成后监测心内排气、评价手术疗效等方面具有明显优势,为微创心脏外科直视手术的成功提供重要保障。 相似文献

Clinical results of minimally invasive mitral valve surgery were retrospectively reviewed, and two different surgical approaches were compared in this study. Between 1997 and 2004, a total of 86 patients with mitral valve disease underwent minimally invasive surgery at the Yonsei University Cardiovascular Center. Age of patients averaged 41.6 +/- 14.0 years and 69 patients were female. Surgical approach included low- sternal incisions with mini-sternotomy, and right parasternal or thoracotomy approach. Either direct aortic or femoral arterial and bicaval cannulations were used in all patients. Patients were divided into two groups according to the method of surgical approach (parasternal (P) vs low-sternal (L)), and the results were compared. Postoperative NYHA functional class improved to 1.1 +/- 0.4 in all patients (no significant statistical difference between two groups). Mean wound length (P: 9.21 +/- 1.10 vs L: 11.24 +/- 0.82 cm, p < 0.05), and mechanical ventilation time (P: 10.42 +/- 4.36 vs L: 12.90 +/- 5.00 min, p=0.04) was significantly shorter in parasternal group, and mean operation time(P:294.74 +/- 59.41 vs. L:259.31 +/- 54.36 min, p=0.03) was significantly shorter in low-sternal group. Mean cardiopulmonary bypass time, and aortic cross clamp time was also shorter in low-sternal group without statistical difference. There were 2 minor wound complications in all patients (p=NS), and no hospital death. Comparing the two different surgical approach of minimally invasive mitral valve surgery, parasternal approach is thought to be more beneficial in reducing postoperative scar, and intubation time. 相似文献
