1/43. Traumatic fracture of the hyoid bone: three case presentations of cardiorespiratory compromise secondary to missed diagnosis.hyoid bone fractures secondary to blunt trauma other than strangulation are rare (ML Bagnoli et al., J Oral Maxillofac Surg 1988; 46: 326-8), accounting for only 0.002 per cent of all fractures. The world literature reports only 21 cases. Surgical intervention involves airway management, treatment of associated pharyngeal perforations, and management of painful symptomatology. The importance of hyoid fracture, however, rests not with the rarity of it, but with the lethal potential of missed diagnosis. We submit three cases with varying presentations and management strategies. All three of our cases incurred injury by blunt trauma to the anterior neck. Two patients required emergent surgical airway after unsuccessful attempts at endotracheal intubation. One patient presented without respiratory distress and was managed conservatively. After fracture, the occult compressive forces of hematoma formation and soft tissue swelling may compromise airway patency. It is our clinical observation that hypoxia develops rapidly and without warning, leading to cardiorespiratory collapse. With endotracheal intubation prohibited by obstruction, a surgical airway must be established and maintained. Recognition of subtle clinical and physical findings are critical to the diagnosis of laryngotracheal complex injuries and may be life-saving in many instances. To ensure a positive outcome, a strong degree of suspicion based on mechanism of injury is mandated.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
2/43. Femorofemoral bypass, even in pregnancy--a case report.A 29-year-old pregnant woman sustained blunt, left lower abdominal trauma, with hip and pelvic fractures, and progressive dissection of an intimal flap in the left iliac artery, which manifested two days later as profound ischemia of the left leg. The patient underwent distal thromboembolectomy, fasciotomies and revascularization of the leg by femorofemoral polytetrafluoroethylene bypass. The patient recovered completely and gave normal birth three months later to a healthy child. Four years after the operation she gave uneventful birth to another child. Various considerations pertinent to this complex traumatic-vascular-gestational state are discussed.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
3/43. Planned complex suicide: report of three cases.Three cases of planned complex suicide in a 3-year period are reported. A 40-year-old man was found dead, in his garage, hanging by his neck, with a gunshot in the head from a pen gun. A 50-year-old man was found dead in the sea with a gunshot to his head. A third man was found in a field hanging by a tree and burned. The investigation of the scenes and the methods used pointed toward a suicidal etiology. The main difference between planned complex suicide and those cases defined in medicolegal literature as combined suicides lies in the complex mechanism used by the victim as a protection against the failure of one of the mechanisms.- - - - - - - - - - ranking = 7keywords = complex (Clic here for more details about this article) |
4/43. Combined brachial plexus and vascular injury in the absence of bony injury.Neurovascular injury to the axillary vessels is well described in association with fracture or dislocation involving the shoulder joint or the humerus. Such injury however can also occur in the absence of bony injury. A case is presented of damage to the axillary artery and brachial plexus following blunt trauma. This case demonstrates that complex neurovascular damage can occur in the absence of fracture or dislocation. The importance of a thorough clinical assessment is highlighted and priorities with regard to diagnosis and management are discussed.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
5/43. Fatal carotid dissection after blunt head trauma.Occurrence of internal carotid artery injuries associated with skull base fracture has been reported. A. report a case of fatal intracranial carotid dissection related to petrous fracture involving the carotid canal. Identification of carotid lesions may be difficult and generally related to appearance of unexpected neurological deficit. skull base fractures may be considered an indirect sign for detection of vascular injury. Patterns of the fracture are of paramount importance; routine CT scan may fail to detect basilar fractures and high definition fine-cut CT scan should be executed to carefully identify and evaluate fractures. Temporal and sphenoid bone fractures are common in head trauma and involvement of the course of the carotid artery is frequent. The involvement of the intracranial carotid artery course represents a direct risk factor for lesions of the petrous, lacerum and cavernous segments of the carotid artery. early diagnosis of post-traumatic vascular injury may lead to prognosis improvement because of effectiveness of heparin anticoagulant therapy. Then vascular screening is recommendable in cases with complex fractures of the skull base and particularly fracturing along the course of the carotid artery. magnetic resonance angiography may be considered the first line diagnostic tools for vascular screening. Angiography may be reserved for patients with a proven lesion or rapid neurological deterioration taking into account the possibility of interventional treatment.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
6/43. Bronchial repair with pulmonary preservation for severe blunt trauma.After a motorcycle accident, a 22-year-old male was diagnosed with multiple rib fractures, left-sided tension pneumothorax, hemothorax and left upper lobe bronchus rupture at its origin. An emergency left thoracotomy revealed an almost complete avulsion of the upper lobe bronchus from the main stem bronchus, a severely damaged pulmonary artery, and a concurrent deep intraparenchymal lower lobe laceration. Since the patient was hemodynamically stable, a decision was made to preserve as much lung as possible. In the event of complex pulmonary trauma, pulmonary preservation is desirable since emergency pneumonectomy is usually associated with high mortality. Early bronchoscopic assessment, careful anesthetic management, and meticulous surgical technique with liberal use of fibrin glue were crucial to successful outcome.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
7/43. Left bronchial disruption and aortic rupture after blunt chest trauma.A 25-year-old male who had been involved in a traffic accident presented with a neurological disorder, bilateral pneumothoraces, and pneumomediastinum. bronchoscopy revealed a complex rupture of the left bronchial tract. MRI revealed a sinus valsalva aneurysm. The bronchial lesion was first repaired via left thoracotomy. 10 days later, the aorta was repaired via sternotomy. In cases of combined bronchial and aortic lesion, a concomitant repair is not mandatory, at least when the aortic lesion appears limited and shows no signs of dissection.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
8/43. Traumatic aortic regurgitation: aortic valvuloplasty controlled by aortoscopy.Traumatic aortic insufficiency is a rare occurrence after blunt chest trauma, and requires surgical treatment. aortic valve replacement has been proposed as the procedure of choice, but primary valve repair is being performed increasingly more often. In a plead for conservative surgery, we report a case of valvuloplasty that was controlled by intraoperative aortic endoscopy. When operative conditions permit aortic valve repair, this should be carried out in order to avoid aortic valve replacement and its potential complications, especially in young patients with healthy valves. Replacement is the safest treatment for complex or multiple injuries of the aortic valve, however.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
9/43. A blunt complex abdominal trauma: total hepatectomy and liver transplantation.A victim of a motor accident was referred to the Emergency Department. He was unconscious, breathing was rapid and shallow, and had a mean arterial pressure of 60 mmHg with a distended abdomen. A peritoneal lavage was positive for blood. An immediate laparotomy showed a massive hepatic injury with bilobar disruptions. After an unsuccessful hepatorrhaphy an extensive perhepatic gauze packing was done. During the operation the patient was massively transfused and high doses of dopamine were used. At the end a relative stability was reached, but a few hours later, due to the high risk of sepsis and abdominal compartment syndrome, a second laparotomy was performed. Despite efforts to reach a good hemostasis, it was decided to perform a total hepatectomy and portocaval shunt. The patient was put on the waiting list for a compatible liver. After 36 h in this anhepatic state, the patient received the new graft. The graft showed immediate recovery. In cases of severe and complex liver trauma, performing a total hepatectomy followed by liver transplantation is justified.- - - - - - - - - - ranking = 5keywords = complex (Clic here for more details about this article) |
10/43. Video-assisted repair of an eventrated left hemidiaphragm.Video-assisted thoracoscopic surgery is emerging as a viable approach to increasingly complex intrathoracic therapeutic procedures. Here, we present a case of eventrated left hemidiaphragm caused by a blunt trauma in an elderly man. The diaphragm was repaired successfully using a video-assisted procedure, thus giving the patient the advantages of a minimally invasive operation.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
