Surgical Ciliated Cyst of the Maxilla: A Case-Series of Three Cases

The surgical ciliated cyst is an iatrogenic lesion occurring after surgeries in which the Schneiderian membrane has been exposed, such as in orthognathic surgery or maxillary sinus procedures. This lesion has been infrequently documented in western countries. In this case series, we present three cases of surgical ciliated cysts of the maxilla.

Successful Surgical Salvage for a Patient with Ruptured Coronary Sinus during Percutaneous Ablation for Atrial Fibrillation: A Case Report

Herein, we describe the rare anatomy of an abnormal shunt from the left atrium to the coronary sinus, which ruptured during a percutaneous ablation for atrial fibrillation. The iatrogenic lesion was successfully repaired after emergent extracorporeal membrane oxygenation set up followed by surgical exploration. The patient’s postoperative course was uneventful, and she was regularly followed up without any complications.

Surgical correction of iatrogenic lesion of the median nerve after endoscopic decompression: Case report

Introduction: Carpal tunnel syndrome is neuropathy of compressive origin, surgical treatment can present complications that are difficult to solve, among them, painful neuromas of the peripheral nerves, affecting 2–60% of patients with nerve damage. There is no consensus on the ideal treatment for painful neuroma. Consequently, numerous modalities to treat neuroma pain are described. Case report: Female, 45 years old, presented with a left hand carpal tunnel syndrome clinic. There is a report of having undergone a surgical procedure for decompression of the carpal tunnel with endoscopy, progressing with worsening of symptoms. Another surgical procedure was performed (conventional open route) in the region of the left wrist with intra-op visualization of total nerve rupture. Neurorrhaphy of the median nerve was performed. Patient came to our service complaining of severe pain (VAS 9/10) in median nerve topography associated with paresis of the muscles innervated by the same. Neuroma resection and sural nerve grafting for the tenar motor branch, ulnar and radial median group and patient evolved with significant pain improvement (VAS of 2/10). Discussion: A wide variety of surgical techniques are described to treat painful neuroma. In this case, the success of the chosen tchnique is evidenced by the drop of 07 points in the VAS. Conclusion: It is evident that the endoscopic correction of carpal tunnel syndrome is not without complications and should be indicated with caution. It is necessary to carry out more studies that can evidence the best conduct for each case.

Evaluation of Antigenicity of Components of Tracheal Allotransplant and Effect of Immunosuppressant Regime in a Rodent Model

Background Tracheal transplantation seems to be the logical step in the process of reconstruction of the trachea following a long-segment resection, which is usually done to treat malignant disease or benign stenosis of the airway caused by a traumatic, congenital, inflammatory, or iatrogenic lesion. Immunosuppression following transplant is essential but not ideal after oncoresection. Methods The tracheal allografts, harvested from Sprague Dawley rats, were implanted in the Wistar strain rat. The harvested tracheal grafts were divided into groups and subgroups, based on the layers of trachea, method of decellularization, and immunosuppression. The antigenicity of different layers of trachea and the effect of various decellularization methods were studied within three time frames, that is, day 3, 9, and 15. Result On structural analysis, the day 3 and day 15 samples showed no meaningful comparison could be made, due to extensive neutrophil infiltration in all three layers. The day 9 tracheal grafts showed loss of epithelium, with no signs of regeneration in most of the allografts. The subepithelial lymphoid infiltration was found to be severe in nonimmunosuppressed allografts. The group in which both inner and outer layers were removed showed moderate-to-severe infiltrate of lymphoid cells in all the allografts, but there was no cartilage loss, irrespective of the method of decellularization. The irradiated specimens retained the cartilage but showed extensive ischemic damage. Conclusion Rat trachea is a good model for tracheal transplant research but not adequately sturdy to sustain mechanical debridement. Irradiation and chemical decellularization eliminates the immune response but causes intense ischemic damage. Out of the three time frames, day 9 seemed to be the best to study the immune response. To substantiate the results obtained in this study, the immunohistochemical study of the allografts is needed to be performed among a larger group of animals.

The role of gadoxetic acid-enhanced magnetic resonance cholangiography in the evaluation of postoperative bile duct injury: pictorial essay

Iatrogenic lesion of the bile ducts is a relatively common occurrence during liver surgery, increasing morbidity and mortality rates. T2-weighted magnetic resonance cholangiography and gadoxetic acid-enhanced functional magnetic resonance cholangiography (fMRC) with administration of hepatobiliary-specific contrast medium (gadoxetic acid) are fundamental to the diagnostic imaging approach in patients with such lesions. Here, we present a review of the literature and suggest an imaging approach to biliary tract injury, focusing on clinical cases in which fMRC had an impact on the decision-making process for the management of the affected patients.

The Use Of The Gore® Hybrid Vascular Graft For Treatment Of Complex Iliofemoral Revascularization Procedures

Purpose: To describe the uses and advantages of hybrid vascular grafts (HVGs) for complex iliofemoral revascularization procedures. Case Report: We report 3 cases of iliofemoral occlusions repaired with the Gore HVG, used as an alternative technique to standardized common femoral artery (CFA) endarterectomy associated with iliac stenting or open repair. The indication in each of the 3 cases was different: In the first case, there was an absent CFA secondary to a mycotic pseudoaneurysm, in the second case, an iatrogenic lesion of the posterior wall of the CFA during the intervention was performed, and in the third case, the indication was because of thrombosis of a previous iliofemoral revascularization procedure. Conclusion: Although we only present 3 cases, the Gore HVG can be useful for complex iliofemoral revascularizations, serving as an alternative to standardized CFA endarterectomy plus iliac stenting in cases where there is a damaged or absent CFA, especially in high-surgical risk patients.

Management of an Endodontic-periodontal Lesion caused by Iatrogenic Restoration

ABSTRACT Aim This clinical case report demonstrates the successful management of a complex endodontic-periodontal iatrogenic lesion following a critical evaluation and decision-making process with interdisciplinary treatment strategies. Background Defective dental restorations can affect the periodontal and endodontic health of the teeth. Case report An endodontic-periodontal lesion that resulted from a faulty restoration in a 30-year-old male patient is reported. The management of the case is done through periodontal and endodontic treatment. The detailed method of managing of this type of cases is discussed. Conclusion In conclusion, the use of a systematic diagnosis process will help in the identification and treatment of iatrogenic endodontic-periodontal lesions. Clinical significance The correct management of endodontic-periodontal lesions can impede the loss of the involved teeth. How to cite this article Alfawaz Y.

Intraoperative Macula Protection by Perfluorocarbon Liquid for the Metallic Intraocular Foreign Body Removal during 23-Gauge Vitrectomy

Purpose.To evaluate visual and safety outcomes of 23-gauge (G) pars plana vitrectomy (PPV) with application of perfluorocarbon liquid (PFCL) for intraoperative protection of the macula during intraocular foreign body (IOFB) removal.Methods.Retrospective study of 42 patients who underwent 23 G PPV for IOFB removal from posterior segment with intraoperative PFCL application for the macula shielding. Collected data included corrected distance visual acuity (CDVA), size of IOFB, and complication rate. The mean follow-up period was 12 months.Results. The mean preoperative CDVA was 0.54 logMAR (SD 0.46), and the final mean CDVA was 0.68 logMAR (SD 0.66). All IOFBs were metallic with mean dimensions of 4.6 mm × 2.1 mm. Twenty-two IOFBs were removed through the corneal tunnel and 20 IOFBs through the sclerotomy. No intraoperative iatrogenic lesion of the macula was observed. As a tamponade, silicon oil was applied in 31 eyes, SF6gas in 5 eyes, air in 4 eyes, and 2 eyes required no tamponade. Secondary retinal detachment was observed in 17% of cases, but at the end of the follow-up, all the retinas were attached.Conclusion. PFCL application during PPV is a safe method of protecting the macula from unexpected falling of the metallic IOFB during its removal.
