INTRODUCTION: In the context of Indian combat scenario, maxillofacial injuries from gunshots are uncommon. METHODS: The first section of this study is a case report of a rare instance of metal foreign bodies that were lodged in the parapharyngeal space, deeper to the deep lobe of the parotid right next to the carotid space in the neck. The second section focusses on the unique treatment for blast injuries as well as the variety of imaging procedures that are readily available to assist with surgery, such as plain film, CT, angiography, and occasionally MR imaging...

Afferent baroreflex failure (ABF) is a rare disease. It refers to the clinical syndrome caused by the impairment of the afferent limb of the baroreflex or its central connections at the level of the medulla. The recognized causes include trauma, surgery in related areas (radical neck tumor surgery, carotid endarterectomy), neck radiotherapy, brain stem stroke, tumor growth paraganglioma and hereditary diseases, among which the most common cause is extensive neck surgery or radiotherapy for neck cancer. The main manifestations are fluctuating hypertension, orthostatic hypotension, paroxysmal tachycardia and bradycardia...

There is limited evidence of N-butyl cyanoacrylate (n-BCA) use in endovascular embolization of traumatic face and neck vessel injuries. We investigated the safety and effectiveness of n-BCA for this purpose. We retrospectively analyzed consecutive patients presenting to a Level 1 trauma center between April 2021 and July 2022. We included patients aged ≥ 18 years old with any vessel injury in the face and neck circulation requiring n-BCA embolization. The primary endpoint was n-BCA effectiveness defined as immediate control of active bleeding post-embolization...

Objective: To explore the selection, efficacy and application of indications for parapharyngeal space tumor resection assisted by plasma and HD endoscopic system through oral approach. Methods: The clinical data of 23 patients with parapharyngeal space tumor resection assisted by plasma and HD endoscopic system were retrospectively analyzed in Department of Otolaryngology Head and Neck Surgery, the First Affiliated Hospital of Bengbu Medical University from January 2013 to June 2023. All cases were examined by high-resolution CT and MRI before operation, and some cases were examined by CTA or DSA...

Blunt carotid artery injury (BCI) poses a rare yet severe threat following vascular trauma, often leading to significant morbidity and mortality. We present a case of a 33-year-old male who suffered complete thrombotic occlusion of the right common carotid artery (CCA) following a workplace accident. Clinical evaluation revealed profound neurological deficits, prompting multidisciplinary surgical intervention guided by the Denver criteria (Grade I - disruption inside the vessel that results in a narrowing of the lumen by less than 25%; Grade II - dissection or intramural hematoma causing greater than 25% stenosis; Grade III - comprises pseudoaneurysm formation; Grade IV - causes total vessel occlusion; Grade V - describes vessel transection with extravasation)...

INTRODUCTION: Extracranial carotid artery (CA) pseudoaneurysms are uncommon and can cause embolic stroke, compressive symptoms, or (rarely) can rupture. It is of paramount importance to treat this entity to avoid life-threatening complications. In this study, the authors described a cohort of patients that required open surgical repair. METHODS: This article reported the authors' experience with open surgical repair of extracranial CA pseudoaneurysms by presenting a retrospective review of data at their institution from 2016 to 2022...

We report a case of a 24-year-old patient who presented after a head trauma with a traumatic occlusion of his left internal carotid artery. He underwent diagnostic cerebral angiogram and was found to have a direct left carotid-cavernous fistula (CCF) with retrograde filling from the posterior circulation across the posterior communicating artery. Because of the severe injury to the left internal carotid artery (ICA), reconstructive repair of the ICA was not possible. The patient underwent deconstructive repair of the CCF by coil embolization using a posterior retrograde approach...

BACKGROUND Carotid-cavernous fistula (CCF) is a rare, atypical vascular shunt between the carotid arterial system and the venous channels of the cavernous sinus, classified according to the shunt's anatomy, by etiology (resulting from trauma or occurring spontaneously), or by hemodynamic characteristics (such as low- or high-flow fistulas). CASE REPORT A 62-year-old female patient with poorly controlled arterial hypertension presented with bilateral periorbital edema, conjunctival chemosis, ophthalmoplegia, diplopia, and diminished visual acuity...

BACKGROUND: The stroke rate in blunt cerebrovascular injury (BCVI) varies from 25% without treatment to less than 8% with antithrombotic therapy (ATT). There is no consensus on the optimal management to prevent stroke BCVI. We investigated the efficacy and safety of oral Aspirin (ASA) 81 mg to prevent BCVI-related stroke compared to historically reported stroke rates with ASA 325 mg and heparin. METHOD: A single-center retrospective study included adult trauma patients who received oral ASA 81 mg for BCVI management between 2013 and 2022...

BACKGROUND: Vertebral artery injury is a rare condition in trauma settings. In the advanced stages, it causes death. CASE: A 31-year-old Sundanese woman with cerebral edema, C2-C3 anterolisthesis, and Le Fort III fracture after a motorcycle accident was admitted to the emergency room. On the fifth day, she underwent arch bar maxillomandibular application and debridement in general anesthesia with a hyperextended neck position. Unfortunately, her rigid neck collar was removed in the high care unit before surgery...

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is used to control non-compressible hemorrhage not addressed with traditional tourniquets. However, REBOA is associated with acute kidney injury (AKI) and subsequent mortality in severe trauma patients. Herein, we investigated how the degree of aortic occlusion alters AKI in a porcine model. Female Yorkshire-cross swine (n=16, 68.1±0.7Kg) were anesthetized, and had carotid and bilateral femoral arteries accessed for REBOA insertion and distal and proximal blood pressure monitoring...

Bilateral traumatic dissections of the cervical internal carotid artery (ICA) are rare complications of polytrauma. A thorough literature review was performed, and data from selected studies were analyzed to assess the trends in clinical presentation, modes of trauma, management protocols, and clinical outcomes. The reported outcomes were categorized and graded into optimal, intermediate, and poor outcomes. We describe a rare case of bilateral dissection of ICA in a 31-year-old woman who was involved in a motor vehicle accident...

BACKGROUND: Three-point seat belt restraints have been attributed to blunt cerebrovascular injury (BVCI), injury to the carotid or vertebral arteries. Although previous studies have not found a seat belt sign to be a significant predictor for BCVI, it is still used to screen patients for BCVI. OBJECTIVE: This study aims to determine risk factors for BCVI within a cohort of patients with seat belt signs. METHODS: We conducted a retrospective cohort study using our institutional trauma registry and included patients younger than 18 years with blunt trauma who both had a computed tomography angiography (CTA) of the neck performed and had evidence of a seat belt sign per the medical record...

OBJECTIVE: This study aimed to utilize a hemorrhagic shock pig model to compare two hemodynamic monitoring methods, pulse index continuous cardiac output (PiCCO) and spectral carotid artery Doppler ultrasound (CDU). Additionally, we sought to explore the feasibility of employing CDU as a non-invasive hemodynamic monitoring tool in the context of hemorrhagic shock and fluid resuscitation. DESIGN: Animal experiments. SETTING AND SUBJECTS: Female pigs were selected, and hemorrhagic shock was induced by rapid bleeding through an arterial sheath...

A 3 yr old female spayed Labrador retriever was referred for the treatment of a chronic oropharyngeal stick injury. After computed tomography scan evaluation, the cervical area was explored surgically and a right-sided cervical abscess that contained a wooden stick was identified adjacent to the vagosympathetic trunk and carotid artery. The ipsilateral mandibular salivary gland was resected concurrently given its abnormal appearance, and histology confirmed inflammation and necrosis of the gland, which was suspected to be due to direct trauma from the foreign body...

A 16-year-old warmblood mare was referred with a progressive history of behavioral changes and left-sided blindness. Following neuroanatomical localization to the forebrain, magnetic resonance imaging of the head revealed a well-delineated, 4.5 cm in diameter, round pituitary mass causing marked compression of the midbrain and optic chiasm. Euthanasia was recommended but declined by the owners. Veterinary specialists and a human neurosurgeon collaboratively prepared for surgical case management. A novel navigated transmandibular lateral transsphenoidal approach was developed to access the region of the sella turcica and practiced on cadaver specimens...

INTRODUCTION: Cervicocephalic arterial dissections (CADs) occur in 3 cases per 100,000 individuals across all ages. Multiple simultaneous CADs are found in 13 to 22% of cases, and three or more dissections occur in approximately 2%. CADs might result from multifactorial intrinsic deficiencies of vessel wall integrity and extrinsic factors, e.g., minor trauma. CASE PRESENTATION: A young gentleman presented to the emergency department with a sudden onset of a spinning sensation of surrounding, left side arm weakness, blurring of vision, and an NIHSS score of 4...

BACKGROUND: The optimal stenting approach for traumatic pseudoaneurysms (PSA) of the extracranial internal carotid artery (ICA) remains underinvestigated. We present a case of a traumatic pseudoaneurysm of the extracranial ICA managed with stenting and review of prior published similar cases. METHODS: The systematic review followed PRISMA-S guidelines and included studies that investigated traumatic pseudoaneurysms of the extracranial ICA managed by stent placement...
