Short-term effects of extended adventitial inversion with graft eversion anastomosis technique in the root treatment of acute type A aortic dissection / 中国胸心血管外科临床杂志

@#Objective    To evaluate the short-term therapeutic effect of extended adventitial inversion with graft eversion anastomosis technique in the root treatment of acute type A aortic dissection (ATAAD). Methods    From November 2019 to July 2020, 28 patients with ATAAD were treated by extended adventitial inversion with graft eversion anastomosis technique in the Department of Cardiovascular Surgery, Dalian Municipal Central Hospital, including 19 males and 9 females, aged 60.11±11.11 years. The intima of the ascending aorta was trimed to 5 mm above the sinotubular junction. The adventitia of the ascending aorta was longitudinally cut to the reserved intima margin along the junction of the three aortic valves. The extended adventitial inversion was sutured continuously, no coronary sinus was sutured over the aortic annulus, and the left and right coronary sinus was sutured above the coronary ostium. The anastomotic graft was everted and inserted into the aortic lumen, and the everted graft was continuously sutured at the level of sinotubular junction which was 5 mm away from the edge of graft. Results    There was no intraoperative death, intractable root hemorrhage, residual root false lumen, root dilatation, anastomotic hematoma or other complications. There was no recurrence of the pain in the back of all patients, and the results of the CT angiography were not significantly changed. In 22 patients with no regurgitation, only 1 (4.55%) patient had a mild regurgitation. In 6 patients with mild aortic regurgitation, the disappearance rate of regurgitation was 50.0% (3/6). Conclusion    The treatment of extended adventitial inversion with graft eversion anastomosis technique in the root treatment of aortic dissection eliminates the residual dissection at the root. The anastomotic hemorrhage is prevented, the root structure of aortic dissection is reconstructed and strengthened, the root function is restored, and the possible expansion of the root is prevented. The short-term results are satisfactory.

Tratamiento de la fractura conminuta de patela: ¿existen diferencias entre realizar o no una eversión? / Treatment of comminuted patellar fracture: are there differences between performing or not performing an eversion?

OBJETIVO Comparar los resultados clínicos, funcionales e imagenológicos de dos técnicas quirúrgicas para el manejo de fracturas conminutas de patela: con y sin eversión patelar. MÉTODOS En una serie de casos retrospectivos de fracturas conminutas de patela tratadas en el mismo centro entre 2014 y 2017, con un seguimiento ≥ 3 meses, se hizo una comparación entre el grupo con eversión y el grupo sin eversión. Los criterios de exclusión fueron patelectomía parcial o total, reinserción tendínea, o rehabilitación incompleta. Las variables analizadas fueron edad, sexo, tabaquismo, diabetes mellitus, energía del accidente, tipo de fractura, variables quirúrgicas (banda de tensión, tornillos, alambres, nudos, cerclaje circular), rango de movimiento (RDM) articular postoperatorio, presencia de osteosíntesis sintomática, puntaje de escalas funcionales (de Tegner-Lysholm y de Kujala) al alta definitiva, complicaciones (rigidez articular, infección, trombosis venosa profunda), y variables imagenológicos con tomografías computarizadas pre- y postoperatorias (brecha, desnivel articular > 2 mm, elementos de fijación intraarticular). RESULTADOS En total, 20 de 22 pacientes, 13 con eversión y 7 sin eversión, cumplieron con los criterios de selección. El seguimiento fue de 3 a 12 meses, y no hubo diferencias estadísticamente significativas respecto a las variables demográficas entre ambos grupos, lo cual los hace comparables. Destacaron el tiempo desde el ingreso al alta, con 7 meses para los pacientes con eversión y 5 meses para los sin eversión (p = 0.032), la proporción de pacientes con desnivel articular > 2 mm, con 7.7% para los con eversión y 14.3% para los sin eversión (p = 0.016), y una tendencia a resultados superiores en escalas funcionales para el grupo con eversión. CONCLUSIÓN El tratamiento de fracturas conminutas de patela con eversión parece ser una alternativa viable dados sus resultados imagenológicos y funcionales superiores a los de la técnica habitual.

PURPOSE To compare the clinical, functional and imaging outcomes of two surgical techniques for the treatment of comminuted patellar fractures: with and without eversion. METHODS In a retrospective series of cases of comminuted patellar fractures treated at a single center between 2014 and 2017, with a follow-up 3 months , we performed a comparison between the eversion group and the non-eversion group. The exclusion criteria were partial or total patellectomy, tendon reinsertion, or incomplete rehabilitation. The variables analyzed were age, gender, smoking, diabetes mellitus, the energy of the accident, the fracture type, surgical variables (tension band, screws, wires, knots, circular cerclage), postoperative joint range of motion (ROM), presence of symptomatic osteosynthesis, the scores on the functional scales (of Tegner-Lysholm and of Kujala) at the final discharge, complications (joint stiffness, infection, deep vein thrombosis), and pre- and postoperative computed tomography imaging variables (gap, step-off > 2mm, intra-articular fixation elements). RESULTS In total, 20 out of 22 patients, 13 undegoing eversion and 7 not undergoing eversion, met the selection criteria.. The follow-up ranged from 3 to 12 months, and there were no statistically significant differences regarding the demographic variables between both groups, which makes them comparable. The most remarkable results were the time from admission to final discharge, of 7 months for the patients in the eversion group, and of 5 months for those in the non-eversion group (p » 0.032), the proportion of patients with a step-off > 2 mm, with 7.7% for the eversion group and 14.3% for the non-eversion group (p » 0.016), and a tendency towards higher scores in the functional scales for the eversion group. CONCLUSION The treatment of comminuted patellar fractures with eversion seems to be a viable alternative, given its superior imaging and functional results compared to those of the usual technique.

Plantar Pressure Features under Different Walking Conditions in Patients after Trimalleolar Fracture Surgery / 医用生物力学

Objective To analyze plantar pressure features of patients in injured and healthy sides of the lower limbs under different walking conditions after the trimalleolar fracture surgery, and compare these characteristics with healthy subjects. Methods Twelve Trimalleolar fracture patients and twenty-three healthy subjects were recruited and their plantar pressure characteristics under different walking conditions were tested, including peak pressure, contact area and contact time percentage. Results Comparison between injured and healthy sides: during level walking, peak pressure of the 3rd-5th toe in the injured feet were smaller than those in the healthy sides; in inversion position, peak pressure and contact area of the 3rd-5th toe area in the injured feet were smaller than those in the healthy side; in eversion position, peak pressure, contact area and contact time of the 3rd-5th toe in the injured feet were smaller than those in the healthy sides, and peak pressures of the hindfoot area were larger than those in the healthy sides. Comparison between patients and healthy subjects: under three kinds of walking conditions, peak pressures of the 2nd and 3rd metatarsus bones, the 2nd toe, the 3rd-5th toe, contact area of the 1st-5th toe and contact time percentage of the 2nd toe, the 3rd-5th toe area were all smaller than those of healthy subjects, while contact time of the hindfoot and mid-foot area were all smaller than those of healthy subjects. Conclusions The plantar pressure characteristics of Trimalleolar fracture patients were asymmetrical. Compared with healthy subjects, the plantar pressure features of patients were abnormal during stance phase. Compared with healthy subjects, the motor control ability and stability of patients in eversion positions were decreased. The plantar pressure characteristics at ankle eversion can be used to evaluate ankle joint function.

Dynamic Plantar Pressure Features of Ankle Joints at Different Stress Positions / 医用生物力学

Objective To explore the characteristics of plantar pressure of ankle joints at different limb laterality and different stress positions. Methods Twenty-three healthy subjects were recruited to perform walking trails. Each subject was tested for plantar pressure in ankle neutral position, ankle inversion and ankle eversion through simple custom-designed walkways and plantar pressure plate. The evaluation indices were peak pressure, contact area, contact time percentage, M/L (ratio of sum of medial plantar peak pressure to sum of lateral peak pressure), A/P (ratio of sum of toe peak pressure to heel peak pressure). Results The peak pressure of the first metatarsus bone in the dominant foot was significantly larger than that in the non-dominant foot, and the peak pressure of the fifth metatarsus bone was significantly smaller than that on the non-dominant foot. The M/L of dominant side was significantly larger than that of the non-dominant side. Except for the peak pressures of the mid-foot and the first toe, there were significant differences in other regions among the three ankle positions. The percentage of contact time in each area during inversion was greater than that in neutral position, and the percentage of contact time of plantar regions during eversion was longer than that in neutral position except the second toe. The M/L in inversion, neutral and eversion position were 1.24±0.46, 1.06±0.26, 0.88±0.25. The M/L of dominant foot was greater than that of the non-dominant foot, and the A/P during inversion and eversion was greater than that in neutral positions. Conclusions The stability of the dominant foot was better than that of the non-dominant foot. The standing stability decreased during inversion and eversion. During inversion, the body shifted inward and forward to maintain the stability. During eversion, the center of gravity shifted outward and forward to maintain the stability.

Síndrome de párpado laxo / The lax eyelid syndrome

RESUMEN El síndrome de párpado laxo es un cuadro que con frecuencia pasa inadvertido. Los síntomas que lo caracterizan son generalmente muy inespecíficos, por lo que a menudo los pacientes son diagnosticados erróneamente con conjuntivitis infecciosa crónica, blefaritis o síndrome del ojo seco, lo que puede llevar a un retraso o falta de tratamiento durante meses o incluso años. Se presenta el caso de una paciente de 54 años, atendida en el Servicio de Cirugía Plástica Ocular del Instituto Cubano de Oftalmología "Ramón Pando Ferrer", quien refirió sensación de arenilla, ardor y secreciones. Durante el interrogatorio se constató la presencia de trastornos del sueño y eversión del párpado superior al dormir. Se le diagnosticó un síndrome de párpado laxo y se decidió realizar tratamiento quirúrgico, con el uso de la técnica de acortamiento horizontal del párpado. Al mes de la cirugía se observó la desaparición de toda la sintomatología y un resultado estético muy favorable. Aunque el síndrome del párpado laxo no es potencialmente mortal, puede conducir a condiciones serias que amenazan la visión y ser un indicador de condiciones sistémicas fatales(AU)

ABSTRACT The lax eyelid syndrome is a condition that often goes unnoticed. The symptoms that characterize it are generally very nonspecific, so patients are often misdiagnosed with chronic infectious conjunctivitis, blepharitis, or dry eye syndrome, which can lead to a delay or lack of treatment for months or even years. The case of a 54-year-old patient is presented. The patient was treated at the Ocular Plastic Surgery Service of Ramón Pando Ferrer Cuban Institute of Ophthalmology and reported gritty sensation, burning and secretions. During the interrogation, the presence of sleep disorders and dislocation of the upper eyelid during sleep was found. The patient was diagnosed with lax eyelid syndrome and it was decided to perform surgical treatment, using the horizontal lid shortening technique. One month after the surgery, the disappearance of all the symptoms and a very favorable aesthetic result were observed. Although lax eyelid syndrome is not life-threatening, it can lead to serious conditions that threaten vision and can be an indicator of fatal systemic conditions(AU)

The efficacy of urinary continence in patients undergoing radical prostatectomy with bladder neck extension and mucosal eversion reconstruction anastomosis / 中华泌尿外科杂志

Objective To discuss the efficacy of urinary continence in patients undergoing radical prostatectomy with bladder neck extension and mucosal eversion reconstruction anastomosis.Methods From August 2016 to November 2018,31 patients with prostate cancer underwent laparoscopic radical prostatectomy.The patients were 62-85 years old(mean 74.8 years),and the mean PSA score was 16.5 ng/ml(6.8-34.2 ng/ml).The pathological examination confirmed that the Gleason score was 6-9 and the prostate size was 44-83 ml.All patients underwent laparoscopic radical prostatectomy with bladder neck extension and mucosal eversion reconstruction anastomosis.Surgical procedure:After resection of the prostate in laparoscopic radical prostatectomy,the bladder neck was sutured at 6 o'lock position to narrow the bladder neck (" tennis racquet" reconstruction).The interval was 1 cm,and 2-3 needles were sutured,the distance between the neck of the bladder and the ureter was extended.The bladder neck mucosa and urethral mucosa eversion were performed.The posterior wall of the bladder neck was sutured at interval of 1 cm on both sides of the midline.After the knot was tightened,the posterior wall of the bladder was folded and bladder neck was elevated.The posterior wall of the bladder and the posterior wall of the urethra were sutured to reduce the distance between the bladder and the urethra.Finally,the bladder and urethra were anastomosed.The postoperative urinary continence recovery and the clinical effect were recorded.Results The operation time of 31 patients ranged from 80 to 210,with an average of 139.7 minutes.Intraoperative bleeding was 50-330 ml,with an average of 144.2 ml.None of the patients switched to open surgery during the operation,and there was no injury to large vessels and rectum,and no anastomotic leakage.Postoperative pathology showed 21 cases of pT2 stage,10 cases of pT3 stage,2 cases of positive margin,including 1 case of basal part and 1 case of apex part,both of which received medical castration therapy postoperatively.The surgical margin was positive in 2 cases (6.45％).31 patients removed the urinary catheter in ten days after surgery.17 cases (54.8％) recovered instantly urinary continence;7 cases (22.6％) urinary continence in 1 month after operation;4 cases (12.9％) urinary continence in 3 months after operation;and 3 cases (9.7％) urinary control in 6 months after operation.One case had urinary retention after removing the urinary catheter,and cathetered for 2 more weeks.After pulling out again,the urinary continence was good.Conclusions Laparoscopic radical prostatectomy with bladder neck extension and mucosal eversion reconstruction anastomosis may be helpful for early recovery of urinary continence.

Short-term and long-term efficacy of eversion and patch carotid endarterectomy:a meta-analysis / 中国脑血管病杂志

Objective To systematically review the short-term and long-term efficacy of eversion carotid endarterectomy (eCEA) and patch carotid endarterectomy (pCEA) for the treatment of carotid artery stenosis.Methods The published literature on eCEA and pCEA control studies in medline,PubMed,Ovid,CNKI and CBM (1970.5-2016.10) databases were retrieved by computers.Two reviewers selected literature and extracted data independently according to the inclusion and exclusion criteria.Cochrane Collaboration Network Special Software Rev Man 5.2 was used to analyze the meta-analysis of short-term and long-term outcome measures.Results A total of 1 137 articles were retrieved.Ten studies were included and analyzed (3 of them were randomized controlled trial).A total of 3 213 patients were enrolled,including surgical intervention 3 299 case/time (1 512 in the eCEA group and 1 787 in the pCEA group).The results of meta-analysis showed that:(1) the mean operative time in the pCEA group was shorter 22±8 min than that in the pCEA group.The intraoperative utilization ratio of shunt tube,eCEA was significantly lower than pCEA,they were 12.6 %(53/421) and 50.2% (357/711) respectively (OR,0.11,95%CI 0.08-0.15,P<0.01).The postoperative incidence of stroke within 30 d (OR,0.42,95%CI 0.23-0.76,P=0.004) and the incidence of stroke after 30 d in eCEA were lower than those in pCEA (OR,0.26,95%CI 0.09-0.78,P=0.02).There was significant difference.(2) eCEA reduced the incidence of restenosis at day 30 after procedure (OR,0.57,95%CI 0.38-0.86,P=0.008).Conclusion Compared with pCEA,eCEA has the advantages of reducing the operation time and lowering the utilization rate of shunt tube.At the same time,eCEA can reduce the occurrence of stroke within 30 d and 30 d after procedure,and significantly reduce the incidence of restenosis.

Prolapso uterino em gata - Relato de caso / Uterine prolapse in a cat - A case report / Prolapso uterino en gata ­ Relato de caso

O prolapso uterino em cadelas e gatas é uma emergência reprodutiva na qual ocorre eversão de um ou ambos os cornos uterinos através da vagina, durante ou após o parto. Tal patologia não é frequente em gatas, por isso o presente relato tem o objetivo de descrever um caso de prolapso uterino em uma gata atendida no Hospital Veterinário da Universidade Federal do Piauí. Na anamnese o proprietário se queixou de massa avermelhada na vulva após a expulsão de dois filhotes. Ao exame clínico, observou-se que a massa era o útero prolapsado. O animal foi encaminhado imediatamente ao centro cirúrgico para redução do útero prolapsado e realização de ovariosalpingohisterectomia (OSH). Após a OSH, o animal permaneceu internado durante 24 horas. Findo este período o animal teve alta e apresentou boa recuperação.

Uterine prolapse in dogs and cats is a reproductive emergency in which there is the protrusion of one or both uterine horns through the vagina during or after delivery. This condition is not common in cats, so this report aims to describe a case of uterine prolapse in a cat treated at the Veterinary Hospital of the Federal University of Piaui. Upon anamnesis, the owner complained of a reddish mass in the vulva after the expelling of two kittens. Clinical examination revealed that the mass was the prolapsed uterus. The animal was immediately sent to the operating room for reduction of the prolapsed uterus and an ovariosalpingohisterectomy (OSH) was performed. After OSH, the animal remained hospitalized for 24 hours. After this period, the animal was discharged and recovered well.

Comparative results of conventional and eversion carotid endarterectomy

PURPOSE: Comparative results of conventional carotid endarterectomy (cCEA) and eversion carotid endarterectomy (eCEA) have been reported in many studies. But in Korea, there have been no reports to compare the outcome of the two techniques. Thus, we investigated the results of eCEA compared to cCEA in Yeungnam University Medical Center. METHODS: A total of 120 subjects who underwent CEA were included in this study. Of them, cCEAs were performed in 63 patients and eCEAs were performed in 57 patients. We analyzed the results divided into the early (within 30 days after surgery), midterm (from 30 days up to 1 year after surgery) and late (over 1 year after surgery). RESULTS: Mean age of the patients was 65.9 +/- 7.1 years in cCEA group and 66.8 +/- 7.7 years in eCEA group (P = 0.523). Carotid shunt frequency was higher in the cCEA group (39.7% vs. 19.3%, P = 0.015). There were no statistical differences in the early complications with the exception of a significantly higher risk for new brain lesions in the cCEA group (34.9% vs. 14.0%, P = 0.008). The frequency of complication was same between cCEA group and eCEA group in the midterm. Although there was no statistical significance, the frequency of late complications was higher in the cCEA group compared to eCEA group. Mean follow-up duration was 29.4 +/- 23.5 months. CONCLUSION: These data showed that eCEA was an acceptable procedure and had some advantage compared to cCEA in the aspect of the early and late complication.

The Results of Eversion Endarterectomy for Carotid Artery Stenosis / 대한혈관외과학회지

PURPOSE: Potential benefits of eversion carotid endarterectomy (eCEA) compared with conventional carotid enderterectomy (cCEA) are more simple and faster reanastomosis with a low risk of restenosis. However, in Korea, eCEA is not popular having only one report of eCEA. This study aimed to investigate the results of eCEA. METHODS: From July 2008 to September 2010, authors performed 36 eCEAs for patients with carotid artery stenosis in our hospital. Patients' demographics and clinical data were retrospectively reviewed. Regarding early (<30 days) results including the frequency of postoperative stroke, myocardial infarction, cerebral hyperperfusion syndrome, bleeding, cranial nerve palsy, new brain lesions (NBLs) on diffuse-weighted MRI (DW-MRI) and mortality were examined. Mid-term results such as stroke, death and restenosis after over thirty days were also examined. RESULTS: Mean age was 66.6 years old and 88.9% of the patients were male. Twenty-four patients (66.7%) had a previous neurological event in the preceding 6 months. A carotid shunt was used in 3 cases (8.3%) and mean carotid clamping time was 25.4 minutes. One case (2.8%) of non-disabling ipsilateral stroke, 1 case (2.8%) of wound hematoma and 1 case (2.8%) of cranial nerve palsy developed after operation. DW-MRI was conducted in 27 patients (75.0%) and NBLs were detected in 4 patients (11.1%). One case (2.8%) of restenosis was discovered during the follow-up period (mean, 9.0 months), and there were no strokes or death. CONCLUSION: Early and mid-term postoperative stroke and complication rates of eCEA were acceptable in our series. However, to assess efficacy of eCEA, further large-volumed and long-term follow-up studies are needed.

Early Results of Eversion Carotid Endarterectomy

PURPOSE: Eversion carotid endarterectomy (ECEA) has been used in western countries with acceptable early and late results. However, there has been no report of ECEA in Korea with regard to its safety and efficacy. The goal of the present study was to determine the early results of ECEA in Korea. METHODS: From October 2008 to December 2009, 19 ECEAs were performed on 18 patients by one vascular surgeon. The patient data and radiology results were prospectively collected according to the hospital protocol. The frequency of early postoperative stroke, myocardial infarction and mortality were evaluated. In addition, the frequency of procedure-induced new brain lesions (NBL) detected by diffusion-weighted MRI (DW-MRI) within one day after the procedure and the post-procedural complications were evaluated. RESULTS: All ECEAs were performed under regional anesthesia; shunts were not necessary in any of the cases. Among a total of 19 ECEAs, there were no cases of early postoperative stroke, myocardial infarction or mortality. Other early postoperative complications included one case of temporary cerebral hyperperfusion syndrome and two hematomas that spontaneously resolved. No NBL was detected on the postoperative DW-MRI. The external carotid artery lesion was aggravated in five cases and was detected on CT angiography before discharge. CONCLUSION: The results of this study showed no strokes or NBLs after ECEA under regional anesthesia. ECEA may be used safely for the management of atherosclerotic severe carotid stenosis in Korean patients; however, further study for long-term complications of ECEA is necessary.

Objective:To study the effect of cervical canal mucosa dng excision on cervical columnar eversion in Loop electrosurgical excision procedure(LEEP).Methods:A prospective randomized control trail was performed in 125 cervical intraepithelial neoplasia(CIN)patients.Cervix and cervical canal were conically excised with triangle electrode in 62 patients in the control group;in the study group,a small ring electrode was put into the cervical canal and the cervical canal mucosa was excised about 0.5～0.8cm,after excision as the control group.Follow-up was performed postoperatively in 1,3,6 months respectively.The operation time,the bleeding volume,the rate of cervical columnar eversion and cervical adhesion or stenosis were compared between the two groups.Results:The rate of cervical columnar eversion in the study group (1/63,1.59%)was lower than that in the control group(9/62,14.52%).There was significantly statistical difference between them(P=0.008).There was no statistical differences between them in the operation time,the bleeding volume,and the rate of cervical adhesion or stenosis (P>0.05).Conclusions:The cervical canal mucosa ring excision in LEEP can effectively prevent postoperative cervical columnar eversion.

Defining Inversion/Eversion of the Foot : Is it a Triplane Motion or a Coronal Plane Motion? / The Japanese Journal of Rehabilitation Medicine

The purpose of this study was to resolve the confusion existing in the terminology for describing foot motion, particularly the definitions of inversion and eversion. First, the definitions of foot motion used by the Japanese Association of Rehabilitation Medicine and the Japanese Orthopedic Association were compared with those used by the American Orthopaedic Foot and Ankle Society (AOFAS) and with those used by the International Society of Biomechanics (ISB), to identify agreements and differences. Next, the terminology utilized in the literature was explored by examining several major textbooks and related academic papers retrieved through a search of the PubMed medical literature database. In the definitions of AOFAS and ISB, inversion and eversion, which correspond to triplane motions in the definition used in Japan, were regarded as motions in the coronal plane. Terminology in the textbooks was very diverse. Of the 141 academic papers explored, 92 papers (66%) regarded inversion/eversion as coronal plane motion, and 4 papers (3%) regarded it as a triplane motion. In the remaining 43 papers (31%), the definition was unspecified. In academic articles addressing foot motions, to avoid confusion in terminology, the definitions of inversion and eversion need to be specified.

Conservative management of supination-eversion fractures of ankle / 中华创伤骨科杂志

Objective To study middle-and-long-term results of the conservative management of the supination-eversion fractures of ankle. Methods A retrospective study was done for the 43 patients with supination-eversion fracture of ankle who were treated from February 1999 to August 2004 in our department, and followed up. Five patients belonged to stage Ⅰ , 10 to stage Ⅱ , none to stage Ⅲ and 28 to stage Ⅳ . The average duration of follow-up was 69 months (16 to 84 months). Results The middle-and-long-term results were graded according to the Ankle Hindfoot Clinical Rating System of the American Orthopaedic Foot & Ankle Society(AOFAS). Of the stageⅠ patients, five got satisfactory results. Of the stage Ⅱ patients, nine got satisfactory results and one unsatisfactory. Of the stage Ⅳ patients, 26 got satisfactory results and two unsatisfactory. Conclusions The middle-and-long-term follow-ups show that most of the supination-eversion fractures of ankle can be treated conservatively with a satisfactory result. Surgical treatment should be indicated for those whose conservative management cannot reach satisfactory results.

Scleral Eversion Technique for Porous Polyethylene Orbital Implant after Evisceration

PURPOSE: This study is to describe scleral eversion technique as a modification of evisceration to improve its disadvantages for placement of porous orbital implant and to report the results of placement of porous orbital implants with this technique. METHODS: The medical records of 27 patients with 27 eyes who had undergone evisceration and placement of porous polyethylene orbital implant with scleral eversion technique between November 1998 and January 2000 were reviewed. Surgical technique involved the removal of corneal button and the intraocular contents. Optic nerve was severed, scleral shell was everted, and porous polyethylene orbital implant was implanted into the retroscleral and intraconal space. RESULTS: Orbital implants of 20 mm in diameter were implanted in all patients. The average postoperative follow-up interval was 22.4 months. No patient experienced severe complications like exposure of implant. All of patients showed good motility of orbital implant and 19 patients were satisfied with motility of prosthesis. Eight patients (29.6%) got placement of motility coupling post without significant problems to enhance motility. CONCLUSIONS: Scleral eversion technique is safe and useful for evisceration and placement of porous polyethylene orbital implant. This technique can provide adequate space for adequate size of implant without any tension on wound, thick anterior scleral barrier for implant and more vascular source for fibrovascular ingrowth. Therefore, it decrease exposure rate of implant.

Modification of Horizontal Mattress Suture

Proper suturing technique is essential for obtaining good cosmetic results and for preventing scarring and poor healing of the wound. Characteristics of an ideal wound closure technique include: providing maximal wound eversion; maintaining tensile strength throughout the healing process; being technically simple and fast for the surgeon to perform; and allowing for precise wound edge approximation without leaving suture marks. There are a large variety of suturing methods available to the plastic surgeon and more than one of these techniques may be appropriate for any single wound closure. The simple interrupted suture is the simplest and most frequently employed type of suture. The vertical mattress suture is used principally to ensure eversion of skin edges, but is rarely indicated on the face. A common technique for wound closure is to alternate a vertical mattress suture with a simple interrupted suture along the length of the wound. This report outlines a new method for closing skin wounds which combines the horizontal and vertical mattress sutures. This horizonto- vertical mattress suture is easy and quick to perform, achieves precise wound approximation, provides good eversion of skin edges maintaining uniform tensile strength, reduces the risk of suture marks and gives good cosmetic results, and it can be widely applicable to the whole body area wound, including the face.

Antiplatelet Effect of Hirudin in a Rabbit Carotid Artery Eversion Model

BACKGROUND AND OBJECTIVES: Thrombin and its interaction with platelets play a pivotal role in arterial thrombus formation. Hirudin, an anticoagulant agent derived from medicinal leeches(Hirudo medicinalis), is a unique and specific thrombin inhibitor with no effect on other serine protease. We investigated the inhibitory effect of hirudin on platelet deposition in a rabbit carotid artery eversion model of acute arterial thrombosis. MATERIALS AND METHODS: The everted arterial segments were perfused with 111 Indium-labeled human platelets only(control, n=8), and a mixed solution of 111 Indium-labeled human platelets and hirudin(30, 45, 60, 90 microgram/ml, n=3, respectively). Platelet deposition was calculated by a gamma-counter and confirmed by scanning electron microscopy. RESULTS: 1) Indium-111 labeling efficiency of platelets was 87.0+/-6.6%, and the aggregation of platelets was not changed after labeling. The number of platelets perfused through each arterial segment was 4.3 +/-0.2x10(8) platelets/ml. 2) The control group showed a platelet deposition rate of 23.9+/-7.0 % and a number of platelet deposition of 9.8+/-2.5x10(8) platelets/cm2 . 3) Platelet deposition of arteries perfused with hirudin(60 microgram/ml) was significantly decreased compared with that of the control group(2.9+/-0.6 vs 9.8+/-2.5x10(8)/cm2 , p<0.05). 4) The number of deposited platelets in hirudin-perfused arteries was dose-dependently decreased(30 microgram/ml:6.7+/-1.4x10(8) /cm2 , 45 microgram/ml: 4.8+/-1.7x10(8) /cm2 , 60 microgram/ml: 2.9+/-1.8x10(8)/cm2, 90 microgram/ml:2.9+/-1.4x10(8)/cm2: p<0.05 vs. control, respectively). 5) Scanning electron microscopic examination revealed significantly reduced platelet deposition in hirudin-perfused groups compared with control group. CONCLUSION: Hirudin inhibits effectively platelet deposition and arterial thrombus formation in a rabbit carotid artery eversion model. The antiplatelet effect of hirudin in this model suggests that hirudin may be an useful antithrombotic agent therapeutically useful in the prevention of acute arterial thrombus formation.

Isokinetic Evaluation of Ankle Invertor and Evertor in Patients with Chronic Ankle Sprain

OBJECTIVE: The purpose of this investigation was to document the isokinetic performance deficiencies of the invertor and evertor muscles of chronically sprained ankles. METHOD: Eversion/Inversion testing was performed by a Cybex 6000 isokinetic dynamometer at the speeds of 60degrees/sec and 120degrees/sec on 17 subjects who had unilateral chronic ankle sprain. Values were compared between the involved and uninvolved sides. RESULTS: The inversion peak torque deficits between the involved and uninvolved extremities were significantly greater than eversion deficits at 60degrees/sec and 120degrees/sec. Evertor/Invertor peak torque ratios of involved sides at 60degrees/sec were significantly greater than uninvolved sides. CONCLUSION: We conclude that chronic ankle sprains associate an ankle invertor weakness rather than an evertor weakness. Ankle invertor weakness might be resulted from a disuse atrophy and painful ankle inversion. Further prospective study is needed to determine the relationship between the invertor weakness and the chronic ankle sprain.

The 2 Cases of the Sacrospinous Ligament Fixation for the Massive Eversions of the Vagina after Total Abdominal Hysterectomy / 대한산부인과학회잡지

Massive eversion of the vagina is one of the most disturbing disorders confronting a woman. It is a complex disorder that always surgical, and all defects. The managements is always surgical, and all defects must be repaired concomitantly. Current surgical practice relies primarily on the strength of the endopelvic fascia and certain ligaments. Massive eversion of the vagina can be treated by a variety of transvaginal and transamdominal surgical technique. In most instances a transvaginal approach is useful. If strong cadinal and uteroscral support in not available fiocation of the vginal vault to the sacrospinous ligment is useful. In 1987, Miyazaki introduced his Miya Hook ligature carrier. With this instrume nt, introduction of the needle became safer and easier than with the Deschamp aneurysm needle. We had experienced two cases of massive eversion of vagina after the total abdominl hyst erectomy who were treated succesfully with sacrospinous ligement fixation by using Miya Hook. We report above two cases and review briefly.
