Intraosseous Venous Malformation of the Zygomatic Bone: Virtual Surgical Planning and Reconstruction With Customized CAD-CAM Titanium Implant. | LitMetric
Zygomatic intraosseous vascular anomalies are uncommon. Most cases have been reported without a precise diagnosis. The prevalence is 3:1 women during the fourth decade of life. The study of these lesions includes clinical findings, radiological studies, such as computed tomography and magnetic resonance imaging scans, and a postoperative histological study of the specimen. Biopsy is not recommended because of the risk of bleeding. Complete surgical resection remains the gold standard elective treatment.The case of a patient with an intraosseous venous malformation of the zygomatic bone is presented, detailing the clinical, histological, and radiological characteristics and the surgical treatment with a primary reconstruction through Computer-Aided Design/Computer-Aided Manufacturing customized titanium implant guided by virtual surgical planning with a reduction of surgical time and morbidity in the donor area with optimal functional and aesthetic results.
Introduction: The critical role of emergency physicians in military settings underscores the necessity for a broad and proficient skill set, especially in life-saving procedures such as thoracostomies, endotracheal intubations, and cricothyrotomies, to maintain combat readiness. The current peacetime phase, however, presents challenges in maintaining these skills because of decreased exposure to high-acuity medical scenarios. This decrease in exposure jeopardizes skills retention among military emergency medicine physicians, highlighted by studies showing a significant decline in performance over time because of reduced practice.
Myopericytoma is a rare perivascular myoid neoplasm that typically arises in the dermis or subcutaneous tissue, with an intravascular variant also reported. We present a case of an elderly man with a subcutaneous nodule in his lower leg that had persisted for four decades, accompanied by pain in the last several years. Imaging revealed a 20-mm elongated subcutaneous nodule along with a similar intraosseous lesion in the ipsilateral fibula.
The Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care (SIAARTI) has developed a good clinical practice to address the challenges of treating critically ill patients in resource-limited austere environments, exacerbated by recent pandemics, natural disasters, and conflicts. The methodological approach was based on a literature review and a modified Delphi method, which involved blind voting and consensus evaluation using a Likert scale. This process was conducted over two rounds of online voting.
Patients in emergency situations or life distress most often need a intravenous line (IV) to give them the medications they need. The IV route is the preferred route to treat most of the patients in emergency situations out of hospital or in the emergency room but can be very tricky to obtain. Various alternatives have been developed, such as the intraosseous route, particularly useful in cases of venous collapse (shock, cardiorespiratory arrest), the intramuscular route (anaphylaxis, sedation) or the intranasal route (status epilepticus, analgesia).
Objective: An intraosseous arteriovenous fistula (AVF) is a rare fistula with an intracranial shunted pouch. A case of an intraosseous AVF at the squamous part of the occipital bone with spontaneous occlusion of diploic venous drainage is described.
Case Presentation: The patient, a Japanese woman in her 80s, presented with headaches at the back of the head and a history of multiple unruptured cerebral aneurysms but no recent head trauma.
