Abstract：

Objective To summarize the clinical study of modified total aortic arch replacement and stent elephant trunk technique treatment to patients with DeBakey Ⅰ thoracic aortic dissection. Methods From January 2006 to October 2010, 101 cases of DeBakey Ⅰ aortic dissection were treated by modified total arch replacement and stent elephant trunk technique, in which emergency surgery for 73 cases. There were 76 male and 25 female patients, aged from 21 to 77 years with a mean of(49 ±8)years. Intraoperative ascending aortic replacement in 31 cases, Bentall procedure in 29 cases, Wheat procedure in 7 cases, David procedure in 34 cases. At the same time stent elephant trunk in the left subclavian artery corresponding position was windowed to rebuild the blood supply. Deep hypothermic circulatory arrest cerebral protection was completed by bilateral antegrade cerebral perfusion. Results The mean cardiopulmonary bypass time was(212 ±40)min, mean myocardial occlusion time was(95 ± 16)min, mean circulatory arrest time was (42 ±8)min. Operative mortality was 1 case and hospital mortality was 5 case, which died of septicemia,acute renal failure and hemiplegia complicated with multiple organ failure. Compared with selective cerebral perfusion, the incidence of postoperative cerebral vascular accident and transient neurological dysfunction decreased. Seventy-six cases received aorta CTA before discharged, the closure rate of descending thoracic aortic dissection false lumen was 78. 9%. Seventy-one patients were followed up for 5 to 49 months, 50cases was reviewed by CTA, of which closure rate of descending thoracic aortic dissection false lumen was 88.0%, no late death and re-surgery. Conclusions The modified total aortic arch replacement and stent elephant trunk technique treatment for patients with DeBakey Ⅰ thoracic aortic dissection was safe and effective, with less postoperative complications.     

Effects of thoracic epidural analgesia on lower urinary tract function in women

Aims: The need for an indwelling transurethral catheter in patients with postoperative thoracic epidural analgesia (TEA) is a matter of controversy. Subjective observations are ambivalent and the literature addressing this issue is scarce. As segmental blockade can be achieved with epidural analgesia, we hypothesized that analgesia within segments T4–T11 has no or minimal influence on lower urinary tract function. Thus, we evaluated the effect of TEA on lower urinary tract function by urodynamic studies. Methods: In 13 women with no preoperative lower urinary tract symptoms undergoing open kidney surgery by lumbotomy under TEA, we prospectively assessed changes in urodynamic parameters the day before and 2–3 days after surgery with the patients under TEA. Results: Before versus during TEA, there was a significant increase in postvoid residual (median, 5 ml vs. 220 ml, P < 0.001) and a significant decrease in maximum detrusor pressure (median, 23 cmH₂O vs. 5 cmH₂O, P = 0.001), detrusor pressure at maximum flow rate (median, 18 cmH₂O vs. 5 cmH₂O, P = 0.001), maximum flow rate (median, 12 ml/sec vs. 3 ml/sec, P < 0.001), and voided volume (median, 250 ml vs. 40 ml, P < 0.001). In addition, maximum urethral closure pressure at rest decreased significantly under TEA from median 75 cmH₂O to 56 cmH₂O (P = 0.002). Bladder sensation, maximum cystometric capacity, compliance, and functional profile length at rest were not influenced by TEA. Conclusions: TEA has a significant effect on bladder emptying with clinically relevant postvoid residual (PVR) necessitating (indwelling or intermittent) catheterization or monitoring of PVR.

Gilliatt-Sumner hand or true neurogenic thoracic outlet syndrome. A report on seven operated cases

Background and purpose

The clinical picture of hand atrophy related to a cervical rib or elongated C7 transverse process was well described in the modern literature by Gilliatt and Sumner; in 1970, they reported a series of nine patients whose motor status was stabilized following brachial plexus decompression. We report here seven patients suffering from thoracic outlet syndrome (TOS), who developed hand atrophy, sometimes because of diagnostic delay.

Methods

The patient's charts were analysed retrospectively.

Results

The seven patients were all female; the mean age was 43 years. The first complaints were arm pain and paresthesias lasting six months to 5 years. Three patients were treated with C56/C67 discectomy plus disc prosthesis (one patient), ulnar neurolysis at the elbow (the same patient), carpal tunnel release (one patient), and intravenous immunoglobulins (one patient) before TOS diagnosis. Hand atrophy, severe in five patients, was present at presentation. All patients underwent brachial plexus decompression by the anterior (four), posterior (two), or transaxillary (one) approach. This last approach was completed 18 months later by brachial plexus neurolysis via the anterior approach. Postoperatively, motor deficit was improved in two patients and stabilized in five patients.

Conclusions

Physicians’ unfamiliarity with TOS diagnosis or their reluctance to accept the diagnosis without electrical confirmation can lead to hand atrophy. Brachial plexus decompression at this stage usually stabilizes the deficit.     

Brown-Sequard syndrome revealing intradural thoracic disc herniation

Brown-Sequard syndrome (BSS) is a rare form of severe myelopathy characterised by a clinical picture reflecting hemisection of the spinal cord. This syndrome is mostly due to a penetrating injury to the spine but many other non-traumatic causes have been described. Intradural thoracic disc herniation (TDH) is one of the rare aetiologies of this syndrome. Despite progress in imaging techniques, diagnosis and treatment remain difficult. We retrospectively reviewed one of the largest reported series of six patients with BSS revealing intradural TDH between 2003 and 2007. There was a marked female predominance and the mean age was 44 years. Before surgery, half of the patients had a severe neurological deficit. The mean duration of symptoms until surgery was 8.5 months (range 0.5–24 months). Spine magnetic resonance imaging (MRI) or spine computer tomography scan showed calcified TDH between T5–T6 and T9–T10. The intradural location of the thoracic herniation was strongly suspected from the clinical data. All the patients underwent posterolateral transpedicular surgery with an operative microscope to open the dura mater. The intradural location of the herniation was overlooked in one case and the patient underwent a second procedure. The dura mater was carefully closed. Two patients’ condition worsened immediately after the surgery before slowly improving. All the other patients improved their neurological status immediately after the surgery and at 12 months follow-up. BSS with TDH on the spine MRI scan may be a warning symptom of the intradural location of the herniated disc. In such cases, spine surgeons are advised to use an operative magnification and to open the dura mater to avoid missing this potentially curable cause of severe myelopathy.     

胸部皮肤神经活性监测在心房颤动诊疗中的临床意义

目的：研究胸部皮肤神经活性与心房颤动发生的关系,总结胸部皮肤神经活性监测在心房颤动诊疗中的临床意义。 方法：选取2017.03-2017.05在我科拟接受胸腔镜辅助下房颤微创外科射频消融的孤立性房颤患者36例,其中,阵发性房颤20例,持续性房颤16例。在房颤消融术前,应用Powerlab数据采集分析系统,采集、分析房颤患者的胸部皮肤神经活性。比较分析持续性房颤患者与阵发性性房颤患者之间胸部皮肤神经活性的差异。 结果：持续性房颤患者的胸部皮肤神经活性[1.27±0.27μV（95% CI [1.16,1.41]）]明显高于阵发性房颤患者的胸部皮肤神经活性[1.00±0.34μV（95% CI [0.87,1.14]）]（P=0.013）,持续性房颤患者的心室率[89.44±19.74bpm（95% CI [80.81,99.17]）]也明显快于阵发性房颤患者的心室率[71.25±12.34bpm（95% CI [66.35,76.36]）]（P=0.004）。持续性房颤患者的胸部皮肤神经活性与心室率呈明显的正相关（r=0.719,P=0.002）;阵发性房颤患者的胸部皮肤神经活性与心室率亦呈明显的正相关（r=0.634,P=0.003）。 结论：胸部皮肤神经活性可有效用于评估心脏交感神经活性,与心室率变化呈正相关;不同类型房颤,其胸部皮肤神经活性有所不同,持续性房颤的胸部皮肤神经活性明显高于阵发性房颤,表明持续性房颤的自主神经重构可能较阵发性房颤更严重。

The stability of bilateral sagittal ramus osteotomy and vertical ramus osteotomy after bimaxillary correction of class III malocclusion

Introduction

The purpose of this retrospective cephalometric study was to compare the stability of bilateral sagittal split osteotomy (BSSO) with extra-oral vertical ramus osteotomy (VRO) after correction of class III malocclusion by means of bimaxillary orthognathic surgery.

Methods

The sample comprised 51 consecutively treated patients, 38 females and 13 males, with a mean age of 19.1 years. All had a one-piece Le Fort I osteotomy with maxillary advancement and mandibular setback. VRO was performed in 30 cases, and BSSO was performed in 21 cases. Lateral cephalograms were obtained before surgery, within 1 week of surgery and 1 year after surgery.

Results

The mean forward movement of the maxilla was 5.6 mm in both groups (p < 0.001). The mean horizontal surgical change in the VRO group was 4.4 mm (p < 0.001), and in the BSSO group it was 5.4 mm (p < 0.001). In the VRO group, the horizontal relapse was 1.2 mm (p < 0.001), and in the BSSO group, it was 1.4 mm (p < 0.001).

Conclusion

There was no difference in the stability between the BSSO and VRO groups. The average relapse in the whole sample was 26% of the surgical movement.     

Bilateral cleft lip and nose repair

Over the last three decades bilateral cleft lip and nose repair has been characterised by a trend towards more detailed reconstruction of the nasolabial muscles together with simultaneous correction of the deformity. An understanding of the true nature of the nasal deformity in bilateral cleft lip and palate (BCLP) has gradually emerged, and has inspired new approaches to their repair. This article discusses recent trends and controversies in primary cheilorhinoplasty for BCLP.
