Fiber Optic RealShape (FORS) Technology for Endovascular Navigation in Severe Tortuous Vessels

Purpose: The purpose of this study was to describe the use of a wire and catheters embedded with optical fiber (Fiber Optic RealShape [FORS]) to catheterize tortuous target vessels avoiding radiation. Technique: A virtual biplane vies was simulated coupling traditional x-ray system, preoperative CT scan, and FORS system to treat an isolated hypogastric aneurysm. Despite the complex anatomy, catheterization of all target vessels was possible in 12 minutes with 19 seconds of fluoroscopy time (Radiation Exposure 3.8 mGy×cm2). A minimal invasive endovascular exclusion of the aneurysm was achieved through selective coil-embolization of the iliolumbar artery and implantation of balloon expandable covered stents, thus preserving the perfusion of the superior gluteal artery. Conclusion: FORS guidance allowed catheterization of a target vessel with challenging anatomy with a low radiation exposure.

Outcome of Closure of Wide Based Defects by Various Rotational Flaps

Aim: To observe the outcome of closure of wide based defects by various rotational flaps for meningomyelocele defects. Study setting: Neurosurgery Department, Sheikh Zayed Hospital, Rahim yar khan Duration: From Oct 2018 to Oct 2020, Methodology: We included 15 patients with wide based myelomeningocele anomalies in the neurosurgery department, Sheikh Zayed Hospital, Rahim yar khan. Age ranged from four days to eight years. The flaw had a diameter of between 8x5cm and 12x8cm. Rotational flaps were used to restore soft tissue defects in all cases. Result: In this study, we did posterior intercostal artery perforator flap(superiorly based) in 40% patients, double rotation flap (yin yang) in 26.7% patients, superior gluteal artery perforator flap in 20 % patients and z plasty in 13.3 % patients. Regarding complications, 2 (13.3%) individuals had a superficial wound dehiscence. One individual (6.7%) developed necrosis of the distal portion of the flap, which was conventionally handled. Postoperatively, no neurosurgical problem occurred. After an average of 6 months, no patient experienced reappearance or dural sac herniation. Conclusion: Restoration of large meningomyelocele defects using local rotational flaps is a secure and reliable approach for abnormalities in the lumbosacral region. Keywords: Meningomyelocele, rotational flaps

Complications of Acute Acetabular Fractures Surgical Treatment: Systematic Review

Background.The combination of classical anterior and posterior approaches, as well as their modifications, is recognized as the most effective in acetabular fractures surgical treatment. The use of classical and modified approaches is accompanied by serious intra- and postoperative complications associated primarily with the duration of surgery, significant blood loss, tissue trauma, surgical site infection. The aim of review — to determine the main and most frequent complications associated with surgical approaches to the acetabulum. material and methods. Access to literature sources is carried out in the information systems and databases PubMed/Medline, Embase, Scopus, Сochran Library, eLibrary, Wiley Online Library. Keywords: acetabular fractures, surgical treatment, approach to the acetabulum, total hip replacement.Results. The most common intraoperative complications are incorrect fragments reduction, sciatic nerve injury, less often — intraarticular implant position, damage to the superior gluteal artery and other vessels, among the early postoperative complications - wound infection, both superficial and deep, less often — venous thrombosis. Late postoperative complications are mainly represented by the development of heterotopic ossification, post-traumatic coxarthrosis, less often revealed aseptic necrosis of the femoral head, residual protrusion and secondary femoral head lesion. Conclusion. The main approach to the acetabulum are the ileo-inguinal and the Kocher-Langenbeck approach, as well as their combination.Complications were more common using two approaches, especially in cases of simultaneous use. The main intraoperative complications are the sciatic nerve and the superior gluteal artery injury with posterior approaches, the femoral lateral cutaneous nerve with expanded ilio-femoral approach, and the obturator nerve with anterior approaches.

Surgical anatomy of the superior gluteal artery and internal iliac vein in individuals of the brahimorphic somatotype

Objective: to determine the variants of the syntopy of the internal iliac vein (IIV) and superior gluteal artery (SGA) in individuals of the brachimorphic somatotype.Materials and methods. The material for research was 29 dead bodies of males (from 25 to 82 years) and 11 dead bodies of females (from 28 to 78 years) who had died of causes not related to pelvic pathology. The vascular injection, preparation methods, and statistical processing of the obtained data were used to achieve the objective.Results. It has been found that, regardless of gender, the frequency of variants of the spatial localization of IIV and SGA, in which it is relatively safe to perform a. glutea superior ligation, is approximately equal, which is ≈ 24 % for men and ≈ 23 % for women.Conclusion. The performed study has showed that the variants of IIV and SGA syntopy, in which it is advisable to perform IIA ligation, are much more common than types of the spatial localization of v. iliacainterna and a. glutea superior in which selective ligation of SGA is possible.
