Neck irradiation, carotid injury and its consequences.

Carotid stenosis is a major sequela of head and neck irradiation that has not received the attention it deserves. Its impact on the quality of life of patients can be substantial. This review discusses the incidence, pathogenesis and consequences of radiation-induced carotid stenosis following head and neck irradiation. This review is based on literature search (Medline and Pub Med) and cross-referencing. The incidence of significant carotid stenosis following head and neck irradiation range from 30% to 50%. Patients with carotid stenosis are at increased risk for stroke. Factors such as hypertension, diabetes, smoking and obesity increase the risk. Increased attention to the clinical signs of carotid stenosis and evaluation of these patients with appropriate imaging studies, together with strict implementation of management of hypertension and diabetes and, counseling on obesity and smoking have the potential to reduce the incidence of this sequela of head and neck irradiation. Those patients with severe carotid stenosis can be managed with endarterectomy or carotid artery stenting.

Selective surgical management of zone II gunshot injuries of the neck: a prospective study.

BACKGROUND: The management of penetrating neck trauma remains controversial, with many studies supporting either mandatory exploration or selective conservatism. METHODS AND RESULTS: This is a prospective study of 75 patients with gunshot injuries to zone II of the neck. Forty patients (53.3%) underwent immediate exploration because of clinical indications or positive initial investigations. A 7.5% incidence of unnecessary explorations, a 5% mortality rate, and average hospital stay of 10.5 days were noted. Thirty-five patients with negative clinical or investigational findings underwent observation with constant monitoring. A 5.7% incidence of missed injuries, no mortality, and an average hospital stay of 3.5 days were noted for these patients. CONCLUSIONS: We suggest that conservative management in gunshot injuries confined to zone II of the neck selectively supplemented by appropriate investigations is a viable proposition in this type of injury. Further contemporary studies reporting specifically on this injury will enable us to reach statistically significant conclusions.

[Penetrating injuries of the neck: review of 16 operated cases].

BACKGROUND: Cervical lesions from penetrating trauma in the neck are increasing together with other types of trauma especially in big towns. Nevertheless in Italy a Register of Trauma is still lacking and no guidelines are available. Conservative management is also advocated and is still under discussion. Comparison of diagnostic tools and evaluation of different treatments in case of vascular damage is also expected. PATIENTS AND METHODS: A series of 16 penetrating lesions of the neck including various degrees of severity were treated over a span of 5 year. The penetrating trauma was due to stab wound or similar causes in 11 cases; to gunshot wound in 3 and to traffic accidents in 2 cases. All of them received surgical treatment. In 56% of cases (9/16) of cases vascular structures were involved, in 4 cases the aerodigestive tract was involved (25%), and in 1 the spinal cord was injured (6%) resulting in a Brown-Sequard syndrome. Other patients presented with superficial lesions, and reconstruction of muscles by simple suture or ligature of veins could obtain complete healing. RESULTS: The penetrating trauma brought about death in 2 cases (1 stab wound, 1 gunshot wound), while 1 lesion of carotid artery and 4 lesions of jugular vein were successfully repaired. In 1 case of lesion in zone 3 a serious bleeding from damage to lingual artery was cured in spite of the minimal width of the external injury. Hypopharyngeal lesions could be treated in 2 cases. One was associated with lethal vascular damage. In 1 case of tracheal lesion with cervical hematoma and dyspnea, patency of the airways became the main concern and and a cannula was placed in the trachea. The Brown-Séquard syndrome could improve with rehabilitation therapy in 3 years. All of the minimal cervical lesions healed with uneventful course. CONCLUSIONS: The penetrating trauma in the neck may show various degrees of severity: nevertheless, no cervical penetrating trauma should be underestimated in spite of the minimal width of the lesion. Surgical exploration was invariably the preferred treatment in our experience.

Early management and outcome following soft tissue injuries of the neck-a randomised controlled trial.

A total of 108 consecutive patients presenting to our hospital following a soft tissue injury of the neck from a road traffic accident were included in a prospective trial. Each patient was randomised to either early mobilisation using an exercise regime or 3 weeks treatment in a soft collar followed by the same exercise regime. Patients were assessed clinically at 3, 12 and 52 week intervals from injury. No differences were found between the two groups for pain, range of movement or activities of daily living at any of the follow up intervals. The collar treatment group took significantly longer to return to work after injury (17 days) compared with the early mobilisation group (34 days), P < 0.05. Treatment with a soft collar was found to have no obvious benefit in terms of functional recovery after neck injury and was associated with a prolonged time period off work. This study supports the use of an early mobilisation regime following soft tissue injuries of the neck.

A multidisciplinary, multifactorial intervention program reduces postoperative falls and injuries after femoral neck fracture.

INTRODUCTION: This study evaluates whether a postoperative multidisciplinary, intervention program, including systematic assessment and treatment of fall risk factors, active prevention, detection, and treatment of postoperative complications, could reduce inpatient falls and fall-related injuries after a femoral neck fracture. METHODS: A randomized, controlled trial at the orthopedic and geriatric departments at Umeå University Hospital, Sweden, included 199 patients with femoral neck fracture, aged >or=70 years. RESULTS: Twelve patients fell 18 times in the intervention group compared with 26 patients suffering 60 falls in the control group. Only one patient with dementia fell in the intervention group compared with 11 in the control group. The crude postoperative fall incidence rate was 6.29/1,000 days in the intervention group vs 16.28/1,000 days in the control group. The incidence rate ratio was 0.38 [95% confidence interval (CI): 0.20 - 0.76, p=0.006] for the total sample and 0.07 (95% CI: 0.01-0.57, p=0.013) among patients with dementia. There were no new fractures in the intervention group but four in the control group. CONCLUSION: A team applying comprehensive geriatric assessment and rehabilitation, including prevention, detection, and treatment of fall risk factors, can successfully prevent inpatient falls and injuries, even in patients with dementia.

A case of cerebellar infarction caused by vertebral artery injury from a stab wound to the neck.

Vertebral artery injuries are the least common arterial injuries because of the deep location of the vessel in a bony canal. Injury of this vessel has not been associated with neurological deficits, and it is thought that many of these injuries are not recognized. The incidence of vertebral artery injury occurring after a penetration wound to the neck varies from 1.0% in gunshot wounds to 7.4% in stab wounds. However, even with vertebral artery injury in penetration wounds of the neck the association with cerebellar infarction is a rare occurrence. We describe a case of cerebellar infarction caused by vertebral artery injury from a stab wound that severed the vessel between the transverse processes of C3 and C4 with a hypoplastic contralateral vertebral artery. The patient ultimately suffered infarction of the cerebellum due to the lack of preservation of the posterior inferior cerebellar artery blood flow. Management is discussed and the medical literature is reviewed.

Anesthesia in the emergency setting: Part II. Head and neck, eye and rib injuries.

Anesthesia for procedures of the head and neck includes ear field blocks, supraorbital and supratrochlear nerve blocks, infraorbital, mental, mandibular and posterosuperior alveolar nerve blocks. Topical ophthalmic anesthesia is useful in treating a variety of ocular injuries, including corneal abrasion and laceration, chemical/thermal burns, and injuries caused by foreign bodies and contact lenses. The intercostal nerve block is used to manage the pain of rib fractures, thus improving patient comfort, tidal volume and ventilation, and pulmonary toilet.

Physical examination alone is safe and accurate for evaluation of vascular injuries in penetrating Zone II neck trauma.

BACKGROUND: Optimal management of patients with Zone II penetrating neck trauma for vascular injury remains controversial. Retrospective studies have demonstrated that physical examination alone may be as accurate as arteriography in detecting significant cervical vascular injuries requiring operative repair. This study was undertaken to evaluate prospectively the safety and accuracy of physical examination in determining the management of patients with penetrating Zone II neck trauma. STUDY DESIGN: During a 22 month period, 66 consecutive patients presented to our Level I trauma center with penetrating neck trauma. Determination of the vascular status of these patients was based on physical examination alone if the injury was located in Zone II and there was no definite sign of vascular injury. Patients were observed for at least 23 hours. Patients admitted during the first year of the study underwent ultrasound examination of the carotid artery within 48 hours to assess for injuries. RESULTS: Thirty-six patients met admission criteria. Two patients had large lacerations requiring operative debridement and closure. Six patients underwent arteriography because of the proximity of the vertebral arteries to the injury tract, the trajectory also included Zone I or III, or there were equivocal signs of vascular injury. Each arteriogram was negative. Of the remaining 28 patients, none had any evidence of a vascular injury during hospitalization or follow-up period (mean of 1.8 months). Eighteen of the 28 patients had carotid ultrasounds, none of which showed injuries requiring operative intervention. CONCLUSIONS: Patients with Zone II penetrating neck injuries and no definite signs of vascular injury can be safely and accurately managed on the basis of physical examination alone. Arteriography or ultrasonography are not needed to identify vascular injuries.

[Surgical management of war injuries involving soft tissue defects].

In this article, the authors emphasize that the knowledge of terminal ballistics is important for understanding of the pathophysiology of war wounds. They present their own experiences in the treatment of war wounds in 126 casualties, treated in the Institute of Plastic and Reconstructive Surgery, Department of Surgery, Clinical Hospital Center, Zagreb. About 96% of the wounded sustained extremity injuries, while head, neck and thoracoabdominal injuries appeared in a significantly smaller number of cases. War wound were divided into four main categories with regard to type of injury and extension of soft-tissue defect, thus showing the differences in primary excision and in reconstruction of the wounds; 78.6% of head and neck injuries were treated by primary or early primary reconstruction (within three to five days after the injuries have been sustained), while 45.4% of thoracoabdominal injuries were treated by a secondary closure. The greatest number of sophisticated reconstructions were used in extremity injuries (15 wound were reconstructed by local flaps, while free flaps were used in 8 cases). The authors emphasize the importance of proper primary treatment which enables an early reconstruction. This results in significantly shorter hospitalization, so that 87.5% of patients were treated within 20 days and then transferred to early rehabilitation.

Carotid artery injury produced by blunt neck trauma.

Three patients with extracranial carotid artery injury are presented. The trauma to the neck was blunt and nonpenetrating. Two patients showed the progressive neurologic signs of an intracranial lesion three and seven days respectively after head injuries. Injury to the neck did not appear to be a factor in one and, at most, a minor factor in the other. The provisional diagnostic impression in each instance was subdural hematoma. The third case was found in a patient with brain contusion, fractured mandible, and severe neck contusion, who was investigated by contrast study when he failed to respond. All three patients showed compromise of the lumen of an extracranial internal carotid artery on arteriography and on exploration. Two reacted promptly and well to surgical intervention. The third recovered slowly from the brain contusion, but we believe that additional complications were averted by appropriate intervention.

The management of long bone fractures in the head-injured polytrauma patient.

The polytrauma patient who sustains a significant head injury (head and neck Abbreviated Injury Scale of 3 or greater) will require prolonged and technically demanding operative intervention for musculoskeletal and associated soft tissue trauma. The presence of a head injury may delay the immediate surgical intervention for long bone injuries, which has proven to have major advantages for patient care and well-being. This retrospective review of the Sunnybrook Health Science Centre experience between January 1, 1986, and June 1, 1988, identified 153 polytrauma patients with a significant head injury. Forty-five died from complications unrelated to their long bone injuries or treatment thereof, not surviving long enough to reach the operating room for stabilization of their long bone fractures. The 108 survivors sustained 188 long bone injuries, 63 of which were open fractures. Twenty patients were treated nonoperatively. The 88 patients treated operatively had 12 complications: one peroneal nerve palsy; five cases of sepsis (three in open fractures and all resolving with removal of fixation devices); three malunions; and three cases of delayed union. Sixty-nine patients (78%) were available for long-term follow-up, 64 (93%) making a full recovery. Seven required additional surgery to achieve this goal and another patient awaits an ankle arthrodesis. Examining the head and neck AIS and Injury Severity Score of this group showed that 50 (46%) of these patients were expected to die and 22 (44%) made a full recovery.(ABSTRACT TRUNCATED AT 250 WORDS)

Influence of the crash pulse shape on the peak loading and the injury tolerance levels of the neck in in vitro low-speed side-collisions.

The aim of the present in vitro study was to investigate the effect of the crash pulse shape on the peak loading and the injury tolerance levels of the human neck. In a custom-made acceleration apparatus 12 human cadaveric cervical spine specimens, equipped with a dummy head, were subjected to a series of incremental side accelerations. While the duration of the acceleration pulse of the sled was kept constant at 120 ms, its shape was varied: Six specimens were loaded with a slowly increasing pulse, i.e. a low loading rate, the other six specimens with a fast increasing pulse, i.e. a high loading rate. The loading of the neck was quantified in terms of the peak linear and angular acceleration of the head, the peak shear force and bending moment of the lower neck and the peak translation between head and sled. The shape of the acceleration curve of the sled only seemed to influence the peak translation between head and sled but none of the other four parameters. The neck injury tolerance level for the angular acceleration of the head and for the bending moment of the lower neck was almost identical for both, the high and the low loading rate. In contrast, the injury tolerance level for the linear acceleration of the head and for the shear force of the lower neck was slightly higher for the low loading rate as compared to the high loading rate. For the translation between head and sled this difference was even statistically significant. Thus, if the shape of the crash pulse is not known, solely the peak bending moment of the lower neck and the peak angular acceleration of the head seem to be suitable predictors for the neck injury risk but not the peak shear force of the lower neck, the peak linear acceleration of the head and the translation between head and thorax.
