Because of the high failure rates, large alveolar cleft defects cannot be successfully closed with bone grafting. Vega introduced the use of the hyrax screw for the closure of such defects by distraction osteogenesis. However, his technique was more invasive with a difficult adaptation of the appliance at the surgical table. To overcome these limitations, a completely tooth-borne trifocal distraction appliance was devised and placed after osteotomy in a 22-year-old repaired group 3 cleft patient who had a 15-mm alveolar defect on the right side. The tooth-borne trifocal distraction appliance was successful in the controlled closure of a large alveolar cleft with minimal invasiveness and low costs making this procedure feasible for a greater number of patients.

Abstract Introduction: Congenital atrioventricular block is diagnosed in uterine life, at birth, or early in life. Atrioventricular blocks can be life threatening immediately at birth so urgent pacemaker implantation techniques are requested. Reasons can be cardiac or non-cardiac, but regardless of the reason, operations are challenging. We aimed to present technical procedure and operative results of pacemaker implantation in neonates. Materials and methods: Between June 2014 and February 2021, 10 neonates who had congenital atrioventricular block underwent surgical operation to implant permanent epicardial pacemaker by using minimally invasive technique. Six of the patients were female and four of them were male. Mean age was 4.3 days (0–11), while three of them were operated on the day of birth. Mean weight was 2533 g (1200–3300). Results: Operations were achieved through subxiphoidal minimally skin incision. Epicardial 25 mm length dual leads were implanted on right ventricular surface and generators were fixed on the right (seven patients) or left (three patients) diaphragmatic surface by incising pleura. There were no complication, morbidity, and mortality related to surgery. Conclusion: Few studies have characterised the surgical outcomes following epicardial permanent pacemaker implantation in neonates. The surgical approach is attractive and compelling among professionals so we aimed to present the techniques and results in patients who required permanent pacemaker implantation in the first month of life.

Тhis article presents a clinical case of the surgical treatment of a fracture in the intercondylar eminences of the knee joint in a 7-year-old child. Closed fractures of the intercondylar exaltation are mainly a characteristic of childhood. This type of damage occurs by dysfunction of the knee resulting from instability. Because the fracture of the intercondylar eminences of the knee joint in children is similar to the damage of the anterior cruciate ligament in adults, the current course of knee surgery is a minimally invasive technique. These include fixation of the intercondylar exaltation using video stroboscopy as well as the assistance of various implants (e.g., screw, wire, and Dacron). In the children's Department of Traumatology and Orthopedics of the Federal Center of Traumatology, Orthopedics and Endoprosthesis Replacement in Barnaul, various surgeries are performed, including arthroscopy of the right knee joint, intercondylar exaltation reposition, and fixation of the intercondylar exaltation latch Lupine (De PuyMitek).

A 42-year-old male admitted with a non-ST elevation myocardial infarction was referred for invasive angiographic assessment. Based on preprocedural assessment, the right radial artery approach was selected. Despite possessing none of the consensus risk factors for radial artery spasm, in addition to receiving standard arterial spasm prophylaxis and conscious sedation, the patient suffered very severe radial artery spasm with initial catheter placement, resulting in entrapment of a 5 Fr pigtail catheter within the left ventricle. After exhausting traditional methods for resolution of radial artery spasm, surgical intervention appeared to be the only remaining option for removal of the entrapped catheter. Prior to committing to surgery, use of an axillary nerve block to hinder sympathetic vascular tone was suggested and attempted. This intervention resulted in atraumatic catheter removal. We present a case of very severe radial artery spasm refractory to customary interventions, alleviated with a novel, minimally invasive technique, which spared surgical intervention.

Invasive Techniques

Minimally invasive techniques for repair of extracardiac anomalies in congenital heart disease have evolved over the last 5 years and laid the foundation for the next phase: the repair of intracardiac defects. Fifteen patients (9 females and 6 males) with a median age of 9.8 years (range, 5.2 to 54 years) underwent closure of a secundum atrial septal defect through a small right anterior thoracotomy. The right external iliac artery was cannulated through a small groin incision and the atrial septal defect was repaired during hypothermic fibrillatory arrest for a mean period of 14 ± 5 minutes. The mean length of the thoracotomy was 4.9 ± 0.8 cm (range, 4.5 to 8.8 cm) while the mean length of the groin incision was 3.9 ± 0.5 cm (range, 2.9 to 5.3 cm). In the 3 youngest patients, the external iliac artery was cannulated with an 8F arterial cannula. Direct closure of the atrial septal defect was possible in all patients. The mean operative time was 109 ± 39 minutes. There was no perioperative or late mortality and no morbidity except for a tear in the right femoral artery of a 19-year-old girl. No residual atrial septal defect was observed in any of the patients. Although minimally invasive techniques for repair of intracardiac defects are not fully developed with regard to indications, the procedure described here provided secure closure of the defects with excellent cosmetic results.

Traditionally, pacing leads are placed transvenously, although smaller pediatric patients who require permanent pacemakers may benefit from delaying tranvenous lead placement until they are larger. Alternative, minimally invasive atrioventricular pacing options have not previously existed for this patient population, leaving many of these children with large sternotomies or thoracotomies. Using three port sites and an adjustable shaft dual-needle suturing device, we placed a steroid-eluting, sew-on epicardial lead on the right atrium of a 9-year-old patient. This is one of the earliest reported cases of a minimally invasive technique for sew-on epicardial lead placement on the atrium of a child. Although based on a single case, we believe that this approach is safe, reliable, and reproducible and that it can be used to place leads on any aspect of the heart. Adoption of this technique will allow for earlier atrioventricular pacing, which may decrease the incidence of pacemaker syndrome, and thus improve overall outcomes in this patient population.

Abstract Background Mechanisms underlying the rising burden of non-AIDS comorbidities (NACM) among persons with HIV (PWH) remain unclear. Microvasculopathy may link HIV-related chronic inflammation and premature multimorbidity, similar to diabetes and other conditions characterized by inflammatory end-organ damage. We used a novel retinovascular imaging tool, optical coherence tomography angiography (OCTA), to evaluate the retina as a convenient assessment of microvascular health among PWH. Methods Data from 4 PWH who underwent OCTA (Zeiss CIRRUSTM HD-OCT 5000) at the Emory Eye Center from 2018-2020 were analyzed. Demographics, HIV-specific indices and NACM were summarized at the time of OCTA. Images were reviewed qualitatively and metrics of microvascular health – the foveal avascular zone (FAZ) area and vessel density (VD) from the superficial capillary plexus (SCP) – were calculated by ImageJ. Results The median age was 39 years, 100% were male, 100% were black, 25% had ever smoked, and median body mass index was 25.4 kg/m2. Median time since HIV diagnosis was 19 years, all patients had a history of clinical AIDS, including 2 with prior cytomegalovirus retinitis. Median current CD4 count was 84 cells/mm3, 100% were prescribed antiretroviral therapy and 50% had HIV viral suppression. Prevalent NACM included (each n=1): hypertension, dyslipidemia, diabetes, chronic kidney disease and asthma. Qualitatively, all 7 of the eyes evaluated by OCTA had evidence of microvascular pathology: 2 eyes demonstrated diffuse capillary nonperfusion, while the remaining 5 eyes had focal areas of nonperfusion around the FAZ. Mean FAZ area was 0.31 (SD±0.10) mm2 and mean VD of the SCP was 43.9% (SD±10.9%). Retinovascular pathology identified by fundoscopy and OCTA is shown in the figure. Figure. Retinal imaging of a PWH with bilateral retinal vasculitis. Fundus photos of the right (A) and left (C) eyes show retinal vasculitis highlighted by the red arrows. OCTA of the right (B) and left (D) maculae (3X3 scan Zeiss AngioplexTM) show the FAZ areas outlined in yellow, both of irregular contour. OCTA of the left macula demonstrates areas of significant flow voids marked by the asterisks and the FAZ area is enlarged. Conclusion Among patients with longstanding HIV, OCTA identified microvascular abnormalities in all retinae examined. Retinovascular evaluation by OCTA is a feasible, non-invasive technique for assessing microvascular health and findings support additional study in a larger, more diverse group of PWH. Screening tools targeting microvasculopathy among PWH may aid in earlier detection of those at greatest risk of NACM and allow for aggressive risk-modification strategies.

Abstract Background The quest for better patient outcomes is driving to the development of minimally invasive spine surgical techniques. There are several evidences on the use of microsurgical decompression surgery for degenerative lumbar spine stenosis; however, few of these studies compared their outcomes with the traditional laminectomy technique. Objectives The aim of our study was to compare outcomes following microsurgical decompression via unilateral laminotomy for bilateral decompression (ULBD) of the spinal canal to the standard open laminectomy for cases with lumbar spinal stenosis. Subjects and methods Cases were divided in two groups. Group (A) cases were operated by conventional full laminectomy; Group (B) cases were operated by (ULBD) technique. Results from both groups were compared regarding duration of surgery, blood loss, perioperative complication, and postoperative outcome and patient satisfaction. Results There was no statistically significant difference between both groups regarding the improvement of visual pain analogue, while improvement of neurogenic claudication outcome score was significant in group (B) than group (A). Seventy-three percent of group (A) cases and 80% of group (B) stated that surgery met their expectations and were satisfied from the outcome. Conclusion Comparing ULBD with traditional laminectomy showed the efficacy of the minimally invasive technique in obtaining good surgical outcome and patient satisfaction. There was no statistically significant difference between both groups regarding the occurrence of complications The ULBD technique was found to respect the posterior spinal integrity and musculature, accompanied with less blood loss, shorter hospital stays, and shorter recovery periods than the open laminectomy technique.
