Efficacy of high-intensity focused ultrasound cycloplasty in glaucoma and its influencing factor / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To evaluate the efficacy of high-intensity focused ultrasound cyclo plasty(UCP)in the treatment of glaucoma and to investigate related influencing factors.METHODS: The study involved a total of 110 patients(134 eyes)who received UCP treatment between January 2019 and January 2022 at three medical centers: Tianjin Eye Aier Eye Hospital, Chongqing Aier Eye Hospital, and Chongqing Nanping Aier Eye Hospital. Patients were classified into three categories: primary angle-closure glaucoma, primary open-angle glaucoma, and secondary glaucoma. Best corrected visual acuity, intraocular pressure, and the usage of anti-glaucoma medications, etc., were recorded at 6 and 12 mo postoperatively.RESULTS: After 6 months of the UCP procedure, statistically significant differences in intraocular pressure were observed across all groups(all P<0.05). At 12 mo postoperatively, intraocular pressure of the primary angle-closure and primary open-angle glaucoma groups showed differences(all P<0.05). Notably, there were no significant changes in visual acuity at either the 6 or 12 mo compared to preoperative values across all patient groups(all P>0.05). Furthermore, the study identified a statistically significant correlation between the changes in intraocular pressure at 6 mo and factors such as age, history of previous glaucoma surgery, baseline white-to-white(corneal diameter), and the extent of UCP treatment(all P<0.05).CONCLUSION: The UCP procedure has been demonstrated to effectively lower intraocular pressure in patients with glaucoma. The efficacy appears to be influenced by variables including patient age, previous glaucoma surgery history, baseline white-to-white(corneal diameter), and the scope of UCP treatment. Importantly, UCP treatment did not adversely affect visual acuity, underscoring its favorable safety profile.

OBJECTIVE@#To observe the clinical efficacy of intercondylar fossa plasty in preventing intercondylar fossa impingement syndrome after high tibial osteotomy.@*METHODS@#From August 2018 to August 2020, 84 patients with inverted knee osteoarthritis were treated by arthroscopy combined with high tibial osteotomy, and were divided into two groups with 42 cases in each group according to different surgical methods. In the intercondylar fossa plasty group, there were 13 males and 29 females, age ranged from 52 to 67 years old with an average of(58.27±4.32) years old, and arthroscopic intercondylar fossa plasty was performed first, and then high tibial osteotomy. In the arthroscopic cleansing group, 16 males and 26 females, age ranged from 50 to 71 years old with an average of (59.02±5.14) years old, underwent arthroscopic cleansing and then high tibial osteotomy. Postoperative treatment was evaluated using visual analogue scale(VAS), hospital for special surgery (HSS) score for the knee, and the occurrence of intercondylar percussa impingement.@*RESULTS@#All 84 patients were followed up, the duration ranged from 12 to 18 months with an average of (14.1±1.6) months. The VAS and HSS score of knee joint at 6, 12 and 18 months after surgery were significantly improved compared with preoperative period, and there was no significant difference between the two groups (P>0.05), but the incidence of intercondylar fossa index and intercondylar fossa impact between the two groups was significantly compared 18 months after surgery (P<0.05).@*CONCLUSION@#Intercondylar fossa plasty can effectively prevent the incidence of intercondylar fossa impact after high tibial osteotomy, and has a more significant effect on postoperative knee pain and function improvement.

Percutaneous vertebral-disc plasty for very severe osteoporotic vertebral compression fractures / 中华创伤骨科杂志

Objective:To investigate the clinical efficacy of percutaneous vertebral-disc plasty (PVDP) in the treatment of very severe osteoporotic vertebral compression fractures (vsOVCF).Methods:A total of 26 patients with vsOVCF were treated by PVDP at Department of Spine Surgery, The Second Affiliated Hospital, Nantong University from November 2019 to August 2021. They were 8 males and 18 females with an age of (77.9±5.2) years. Fracture sites: T11 in 9 cases, T12 in 13 cases, L1 in 7 cases, and L2 in 2 cases. The loss of vertebral height exceeded 2/3 of its original height. The curative effects were evaluated by comparing the visual analogue scale (VAS), Oswestry disability index (ODI) and local kyphosis angle (LKA) at preoperation, 1 day postoperation and the last follow-up.Results:This cohort was followed up for 12(10, 15) months. No obvious neurological damage or other serious complications occurred. The VAS scores [(2.9±0.7) and (2.2±0.7) points] and ODIs [28.0%±4.8% and 16.9%±4.0%] at 1 day postoperation and the final follow-up were significantly lower than the preoperative values respectively [(6.7±0.8) points and 66.7%±6.0%], and the values at the last follow-up were significantly lower than those at 1 day postoperation ( P<0.05). The LKAs at 1 day postoperation and the last follow-up (18.1°±4.1° and 19.5°±4.4°) were significantly smaller than that before operation (32.0°±5.2°) ( P<0.05), but there was no significant difference between 1 day postoperation and the last follow-up in LKA ( P>0.05). Conclusion:PVDP is an effective surgical treatment of vsOVCF, because it can relieve pain and improve local kyphosis with satisfactory clinical outcomes.

Strategy of laparoscopic treatment of right posterior bile duct hepatolithiasis / 中华消化外科杂志

Hepatolithiasis is a common biliary disease in China. Surgical treatment principles of hepatolithiasis include "removing lesions, cleaning stones, correcting strictures, recovering the drainage and preventing the recurrence". Laparoscopic techniques have been increasingly applied in surgical treatment of hepatolithiasis recently. Right posterior bile duct is a predilection site of hepatolithiasis. Due to its unique anatomy, right posterior lobectomy, right posterior bile duct lithotomy and plasty remain challenging under laparoscopy. Based on relevant literatures and clinical experiences, the authors explore the strategy of laparoscopic treatment right posterior bile duct hepatolithiasis, aiming to provide reference for surgical colleagues.

New progress in diagnosis and treatment of congenital laryngomalacia in infants / 临床耳鼻咽喉头颈外科杂志

Congenital laryngomalacia is the most common disease causing laryngeal stridor in infants. The pathogenesis has not yet been clearly concluded. It may be related to abnormal development of laryngeal cartilage anatomical structure, neuromuscular dysfunction, gastroesophageal and laryngeal reflux disease, etc. The typical manifestations of the disease are inspiratory laryngeal stridor and feeding difficulties, which can be divided into mild, moderate and severe according to the severity of symptoms. The diagnosis is mainly based on clinical symptoms, signs and endoscopy, among which endoscopy is an important diagnostic basis. The treatment of laryngomalacia depends on the severity of symptoms. Mild and some moderate congenital laryngomalacia children can be relieved by conservative treatment, and severe and some moderate congenital laryngomalacia children should be treated by surgery. Supraglottic plasty is the main surgical method, which can effectively improve the symptoms of laryngeal stridor, dyspnea, feeding difficulties and growth retardation in most children, and the surgical effect is good.

Application and development of totally thoracoscopic mitral valve plasty / 中国胸心血管外科临床杂志

@#Thoracoscopic minimally invasive technology has been used in mitral valve plasty since 1990s. Totally thoracoscopic mitral valve plasty has the advantages of small trauma, beautiful incision and rapid postoperative recovery. It is favored by more and more patients and cardiac surgeons. However, according to the reports, the proportion of totally thoracoscopic mitral valve surgery in China is still low. Mitral valve plasty via the totally thoracoscopic approach is still controversial in terms of population adaptation, perioperative complications and long-term prognosis. In addition, the technical difficulty and the long training cycle of surgeons also limit the popularization of this technology. By summarizing the existing literature, this paper analyzes the application and development of totally thoracoscopic approach in comparison with the traditional median thoracotomy mitral valve plasty.

A Case of Mitral Regurgitation and Aortic Regurgitation Complicated with Coronary Sinus Ostium Stenosis / 日本心臓血管外科学会雑誌

Retrograde myocardial protection plays an important role in cardiac surgery and is widely used. We herein report a rare cardiac surgical case complicated with small coronary sinus ostium in which the cannula of retrograde cardioplegia could not be inserted. A 58 years old man was referred for the treatment of regurgitation and aortic regurgitation. Preoperative ECG gated computed tomography (CT) showed that the orifice of the largest coronary sinus was located in the right atrium with a diameter of only 4 mm with an other 3 smaller orifice in the right atrium and ventricle, which appeared to make it difficult to perform retrograde myocardial protection. The operative finding was consistent with the preoperative CT finding and mitral valve repair and aortic valve replacement were performed using only selective antegrade myocardial protection. We should bear in mind that small coronary ostium exists and preoperative assessment of the size of coronary sinus might be important.

A Case of Tricuspid Valve Repair with a Flexible Band in a Patient with Situs Inversus Totalis / 日本心臓血管外科学会雑誌

Tricuspid annulus has an asymmetric three-dimensional structure with the posteroseptalportion lowest toward the apex from the right atrium and the anteroseptal portion the highest. The tricuspid annulus of a patient with situs inversus has a mirror image of a patient with situs solitus, and the posteroseptal and the anteroseptal portion remains the lowest and the highest toward the apex, respectively, as the situs solitus. Therefore, we assumed that the posteroseptal portion would become higher and the anteroseptal portion would become lower using a conventional three-dimensional rigid ring turned over for tricuspid regurgitation in the situs inversus, and the coaptation of the three leaflets would be poor. In this case, we performed tricuspid annuloplasty using a tricuspid flexible band, mitral valve plasty, left atrial plication, left atrial appendage closure for a situs inversus dextrocardia patient with tricuspid regurgitation, mitral regurgitation, and chronic atrial fibrillation.

Objective:To explore the clinical efficacy of the double eyelid plasty with incision in eyelids margin position and internal fixation.Methods:A retrospective analysis was carried out in 47 patients who underwent double eyelid surgery in the outpatient department of our hospital from September 2015 to June 2017. There were 5 males and 42 females, aged from 17 to 32 (25±4) years. The skin was incised above the eyelid margin of 1-2 mm after anesthesia, orbicularis oculi muscle under the eyelid line, loose organization, and orbital septum fat were stripped and removed. The dermis and the tarsus were sutured under the double eyelid line, and the skin was sutured without any tension.Results:After collecting and analyzing 47 cases from September 2015 to June 2017 in our hospital with this method, we found that all 47 patients achievedⅠincision healing, which showed slight swell, natural and smooth radian of double eyelid, and without complications such as infection, hematoma and ptosis. And this method showed no obvious scar hyperplasia around incision line and thus possessed high patient satisfaction.Conclusions:With the advantage of less trauma, quick recovery, unobvious scar, natural and beartiful double eyelids, this method can be used as a supplementary method for the reconstruction of the blepharoplasty, which is worth promoting.

" Watching without dealing" aortic root repair in the treatment of acute Stanford type A aortic dissection: a prospective observational study / 中华胸心血管外科杂志

Objective:To evaluate the clinical effects of " watching without dealing" aortic root repair technique in acute Stanford type A aortic dissection(ATAAD).Methods:From October 2017 to October 2018, " watching without dealing" technique was performed in ATAAD patients with mild aortic root involvement. The proximal aortic anastomosis was at the level of the sinotubular junction, without " pursuing" complete excision of the intra-sinus dissections. The perioperative clinical data and follow-up imaging results of the patients were collected and analyzed to evaluate early and mid-term efficacy of the technique.Results:A total of 20 patients received " watching without dealing" technique in our hospital, including 15 males and 5 females with a mean age of(48.0±12.1) years old(34-73 years old). The preoperative aortic sinus diameter was(41.3±3.6)mm and the aortic sinotubular junction diameter was(43.9±6.6) mm. All patients underwent ascending aortic replacement and total arch replacement plus frozen elephant trunk surgery. The cardiopulmonary bypass time was(179.5±41.5)min(132~255 min), the cross-clamp time was(120.3±23.7) min(95~180 min), and the circulatory arrest time was(8.8±7.6) min(2~22 min). During perioperative period, no adverse events such as death, secondary opening, renal failure, cerebral infarction, and paraplegia occurred. The CTA examination of the aorta before the patients were discharged showed that all residual false lumen in the sinus disappeared, the diameter of the aortic sinus was(30.8±2.6) mm, and the diameter of the aortic sinotubular junction was(27.2±2.5) mm. The patients were followed up for mean(28.5±7.8) months(3~35 months). No surgical re-intervention of the aortic root occurred. The aortic CTA during follow-up period showed no residual or new dissection in the aortic sinus, the diameters of the aortic sinus and aortic sinotubular junction were(30.9±2.4) mm and(27.5±2.7) mm respectively; the ultrasonic cardiogram showed normal aortic valve structure and function. No statistically significant differences were found when comparing the aortic sinus diameter and aortic sinotubular junction diameter between two time points of at discharge and follow-up.Conclusion:The " watching without dealing" aortic root repair technique for ATAAD is relatively simple to learn and safe in the perioperative period. Early and mid-term follow-up imaging showed normalization of the aortic sinus structure. Further follow-up and observation were necessary to figure out the long-term clinical outcome of this modified aortic root repair.

3D printing-assisted percutaneous balloon dilatation plasty for treatment of osteoporotic calcaneal fractures of Sanders type Ⅱ or Ⅲ in the elderly patients / 中华创伤骨科杂志

Objective:To compare the clinical efficacy between 3D printing-assisted percutaneous balloon dilatation calcaneal plasty (3D-PCP) and conventional open reduction and internal fixation (ORIF) via the extended lateral L-shaped approach in the treatment of osteoporotic calcaneal fractures of Sanders type Ⅱ or Ⅲ in the elderly patients.Methods:Retrospectively analyzed were the data of 36 elderly patients with osteoporotic calcaneal fracture of Sanders type Ⅱ or Ⅲ who had been surgically treated at Department of Orthopaedics, Yixing People's Hospital from June 2012 to June 2018. According to their treatment methods, the patients were divided into a 3D-PCP group [16 cases, 9 males and 7 females with an age of (73.0 ± 3.4) years] and an ORIF group [20 cases, 8 females and 12 females with an age of (71.4 ± 2.6) years]. The 2 groups were compared in terms of hospital stay, operation time, intraoperative fluoroscopy frequency, suture removal time, weight bearing time, fracture healing time, visual analogue scale (VAS) for the surgical site 2 days and one year after surgery, American Foot and Ankle Surgery Association (AOFAS) ankle-hindfoot score, calcaneal imaging parameters (B?hler angle, Gissane angle, and length, width and height of the calcaneus axis) at 2 days and one year after surgery, and postoperative complications.Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability ( P > 0.05). All patients were followed up for 14 to 18 months (mean, 15.6 months). Compared with the ORIF group, the 3D-PCP group had significantly shorter hospital stay, significantly shorter operation time, significantly earlier suture removal, significantly earlier weight-bearing, significantly lower VAS scores at 2 days after surgery, significantly higher AOFAS ankle-hindfoot scores at one month after surgery, but significantly more times of intraoperative fluoroscopy (all P < 0.05). In all patients, the VAS scores at 2 days after surgery were significantly lower than those before surgery, and those at one year after surgery significantly lower than those at 2 days after surgery ( P < 0.05). In all patients, the AOFAS ankle-hindfoot scores at one month after surgery were significantly higher than those before surgery ( P < 0.001). In the ORIF group, the AOFAS ankle-hindfoot scores at one year after surgery were significantly higher than those at one month after surgery ( P < 0.05), but in the 3D-PCP group there was no such a significant difference between one year and one month after surgery ( P > 0.05). There was no significant difference in VAS score, AOFAS score, fracture healing time or postoperative imaging parameters between the 2 groups at one year after surgery ( P > 0.05). There was no significant difference either in the incidence of complications between the 2 groups ( P > 0.05). Conclusion:In the treatment of osteoporotic calcaneal fractures of Sanders type Ⅱ or Ⅲ in the elderly patients, compared with conventional ORIF, 3D-PCP shows advantages of shorter operation time, minimal invasion, quicker incision healing, shorter hospital stay, earlier weight-bearing exercise, and better functional recovery but a disadvantage of increased times of intraoperative fluoroscopy.

Profundaplastia femoral como un proceder inusual en la "era endovascular" / Femoral deep plasty as an unfrequent procedure in the "endovascular era"

Introducción: La arteria femoral común y sus ramas suministran la mayor parte del flujo sanguíneo al muslo, así como a la totalidad de la pierna y el pie, lo que da lugar a la mayor rama del triángulo femoral: la arteria femoral profunda. Objetivo: Exponer la efectividad de la profundaplastia femoral en la "era endovascular". Reporte del caso: Se presenta un caso de enfermedad arterial periférica de múltiples sectores, sin criterio de cirugía revascularizadora (derivación protésica aorto bifemoral). El paciente manifestaba claudicación intermitente a menos de 30 metros, localizada en pantorrilla derecha. En el estudio hemodinámico se apreciaron los índices de presiones tobillo/brazo disminuidos en arteria tibial posterior (0,46) y pedia derecha (0,33). La ecografía doppler del sector femoral derecho evidenció una estenosis de la arteria femoral profunda en su origen, que producía aumento de las velocidades picos sistólicos (479 cm/s), con flujo desorganizado, dilatación posestenótica y oclusión de la arteria femoral superficial en su origen. Se realizó endarterectomía femoral común y profunda con colocación de parche de politetrafloroetileno. El paciente evolucionó sin complicaciones posoperatorias. En el seguimiento se observó mejoría clínica en relación con la distancia de claudicación y un aumento de los índices de presiones tobillo/brazo en arteria tibial posterior y pedia derecha (0,50), respectivamente. Conclusiones: La profundaplastia femoral, aún en la "era endovascular", permanece como un proceder eficaz que resulta alternativa de tratamiento revascularizador en la enfermedad arterial periférica de localización infrainguinal(AU)

Introduction: The normal femoral artery and its branches supply most of the blood flow to the thigh, as well as to the whole leg and foot, which forms the largest branch of the femoral triangle: the deep femoral artery. Objective: Show the effectiveness of femoral deep plasty in the "endovascular era". Case report: It is presented a case of peripheral artery disease in multiple sectors, without surgical criteria of revascularization (derivación protésica aortobifemoral). The patient presented intermittent claudication in less than 30 meters, and it was located in the right calf. In the hemodynamic study, the ankle-arm pressure indexes were dicreased in the posterior tibial artery (0,46) and right dorsalis pedis artery (0,33). The doppler echocardiography of the right femoral sector confirmed a stenosis in the deep femoral artery in its origin, which produced an increase in the peak systolic velocity (479 cm/s), unorganized flows, poststenotic dilatation and occlusion of the superficial femoral artery in its origin. It was performed a common and deep femoral endarterectomy with colocation of polytetrafluoroethylene patch. The patient evolved without post-surgical complications. In the follow-up, it was observed a clinical improvement in relation with the claudication distance and the increase of the ankle-arm pressure indexes in the posterior tibial artery and right dorsalis pedis artery (0,50), respectively. Conclusions: The femoral deep plasty, still in the ´´endovascular era´´, is an efficient procedure that is an alternative to the revascularization treatment in the peripheral artery disease with infrainguinal location(AU)

Bupivacaine-induced myotoxicity during a continuous perineural femoral block: case report / Miotoxicidad inducida por bupivacaína durante un bloqueo continuo del nervio femoral: reporte de caso

Abstract Introduction: Regional anesthesia is widely used for postopera tive analgesia in total knee arthroplasty (TKA). Although it is a safe and effective procedure, serious complications may still develop. In the event of an unusual or torpid evolution, the possibility of local anesthetic-induced myotoxicity should be suspected. Case presentation: A 54-year old patient, American Society of Anesthesiologists (ASA) II, underwent TKA due to primary gonarthrosis.. The analgesic technique used was a femoral nerve block associated with continuous perineural infusion. 24 hours later, the patient's medical condition deteriorated presenting pain, edema, and functional limitation of the thigh of the operated extremity. The symptoms were suggestive of myotoxicity, confirmed with diagnostic images leading to the removal of the catheter. The patient experienced then a significant improvement and was discharged 5 days after surgery. Conclusion: The diagnosis of myotoxicity from local anes thetics is rare, since its manifestations may be masked by the usual symptoms of the postoperative period. Early identification of the condition is fundamental to reduce its negative impact on the patient's recovery and satisfaction. Since the scope of the damage depends particularly on the concentration and duration of the exposure to the local anesthetic agent, there is a need to implement protocols that enable an effective block with the lowest concentration and volume of the medication.

Resumen Introducción: La anestesia regional es ampliamente usada para la analgesia posoperatoria en la Artroplastia de Reemplazo de Rodilla (ARR). Aunque son procedimientos seguros y efectivos, la posibilidad de complicaciones graves existe. Ante una evolución inusual o tórpida se debe sospechar la posibilidad de miotoxicidad inducida por anestésicos locales. Presentación del caso: En un paciente de 54 años, American Society of Anesthesiologists (ASA) II, se llevó a cabo ARR por gonartrosis primaria. Como técnica analgésica se usó el bloqueo de nervio femoral asociado a infusión continua perineural. 24 horas después el paciente presenta deterioro clínico dado por dolor, edema y limitación funcional en muslo de extremidad operada. Ante síntomas sugestivos de miotoxicidad confirmada por imágenes diagnósticas, el catéter fue retirado. Posteriormente, presentó una mejoría significa tiva y egresó del hospital al quinto día posoperatorio. Conclusiones: El diagnóstico de miotoxicidad por anestésicos locales es poco frecuente debido a que sus manifestaciones pueden estar enmascaradas por los síntomas habituales durante el periodo posoperatorio. Su identificación temprana es funda mental para disminuir el efecto negativo sobre la recuperación y la satisfacción del paciente. Dado que la magnitud del daño depende especialmente de la concentración y la duración de la exposición al anestésico local, es necesario implementar proto colos que permitan lograr un bloqueo efectivo con la menor concentración y volumen posible del medicamento.
