A series of 15 patients with extracranial carotid artery aneurysms: surgical and endovascular treatment.

OBJECTIVES: This is a retrospective review of 15 patients with primary and secondary aneurysms of extracranial carotid arteries treated surgically and endoluminally over 20 years in one centre. PATIENTS AND METHODS: Fifteen aneurysms of extracranial carotid arteries were noticed in the same number of patients: five atherosclerotic, two after previous carotid surgery, six post-traumatic, one inflammatory, one of unknown etiology. All of them were symptomatic. RESULTS: In the group treated surgically some complications occurred in the perioperative time: one haematoma, two transient neurological deficits, one fatal stroke. In the endovascular group of patients no complications occurred after the treatment. One fatal stroke occurred during operation-the patient died on the 43rd postoperative day due to respiratory insufficiency. Two other deaths occurred during the follow-up: one caused by myocardial infarction 10 years after the aneurysm resection, and the second due to a fatal stroke 3 years after aneurysmorraphy. One patient refused treatment and died 9 months after being diagnosed. CONCLUSION: Neurological deficits in patients after neck injuries should arouse the suspicion of the presence of a carotid artery aneurysm. Open repair remains the method of choice in treating carotid artery aneurysms but endovascular procedures create the possibility of treating extracranial aneurysms in selected cases when open surgery is not recommended.

Developmental biomechanics of the cervical spine: Tension and compression.

Epidemiological data and clinical indicia reveal devastating consequences associated with pediatric neck injuries. Unfortunately, neither injury prevention nor clinical management strategies will be able to effectively reduce these injuries or their effects on children, without an understanding of the cervical spine developmental biomechanics. Thus, we investigated the relationship between spinal development and the functional (stiffness) and failure biomechanical characteristics of the cervical spine in a baboon model. A correlation study design was used to define the relationships between spinal tissue maturation and spinal biomechanics in both tension and compression. Eighteen baboon cervical spine specimens distributed across the developmental spectrum (1-26 human equivalent years) were dissected into osteoligamentous functional spinal units. Using a servo-hydraulic MTS, these specimens (Oc-C2, C3-C4, C5-C6, C7-T1) were non-destructively tested in tension and compression and then displaced to failure in tension while measuring the six-axes of loads and displacements. The functions describing the developmental biomechanical response of the cervical spine for stiffness and normalized stiffness exhibited a significant direct relationship in both tension and compression loading. Similarly, the tensile failure load and normalized failure load demonstrated significant maturational increases. Further, differences in biomechanical response were observed between the spinal levels examined and all levels exhibited clinically relevant failure patterns. These data support our understanding of the child cervical spine from a developmental biomechanics perspective and facilitate the development of injury prevention or management schema for the mitigation of child spine injuries and their deleterious effects.

The amelioration of symptoms in cervical spinal stenosis with spinal cord deformation through specific chiropractic manipulation: a case report with long-term follow-up.

OBJECTIVE: To describe the chiropractic management of a patient with paresthesia on the entire left side of her body and magnetic resonance imaging (MRI)-documented cervical spinal cord deformation secondary to cervical spinal stenosis. CLINICAL FEATURES: A 70-year-old special education teacher had neck pain, headaches, and burning paresthesia on the entire left side of her body. These symptoms developed within hours of being injured in a side-impact motor vehicle accident. Prior to her visit, she had been misdiagnosed with a cerebrovascular accident. INTERVENTION AND OUTCOMES: Additional diagnostic studies revealed that the patient was suffering from cervical spinal stenosis with spinal cord deformation. Two manipulative technique systems (Advanced Biostructural Therapy and Atlas Coccygeal Technique) unique to the chiropractic profession and based on the theory of relief of adverse mechanical neural tension were administered to the patient. This intervention provided complete relief of the patient's complaints. The patient remained symptom-free at long-term follow-up, 1 year postaccident. CONCLUSION: There is a paucity of published reports describing the treatment of cervical spinal stenosis through manipulative methods. Existing reports of the manipulative management of cervical spondylosis suggest that traditional manual therapy is ineffective or even contraindicated. This case reports the excellent short-term and long-term response of a 70-year-old patient with MRI-documented cervical spinal stenosis and spinal cord deformation to less traditional, uniquely chiropractic manipulative techniques. This appears to be the first case (reported in the indexed literature) that describes the successful amelioration of the symptoms of cervical spinal stenosis through chiropractic manipulation. More research into the less traditional chiropractic systems of spinal manipulation should be undertaken.

All-terrain vehicle-related maxillofacial trauma in the pediatric population.

PURPOSE: Nearly 40% of all-terrain vehicle (ATV) crash-related fatalities involve pediatric patients, with many of these patients dying from head and neck injuries. West Virginia is in a unique position to examine these injuries because of its high rate of ATV use. This study examines craniofacial ATV-related trauma in children. PATIENTS AND METHODS: We conducted a single-center, retrospective, descriptive study of 26 children presenting with a craniofacial injury(ies) resulting from an ATV crash from January 2001 to December 2004. RESULTS: Twenty-six children (65% boys) with a mean age of 13.1 years presented with craniofacial injuries during the study period. Two patients were helmeted. Mortality was 3.8% (n = 1, head injury related, postinjury day 3). Patients were most often drivers of the ATV (65%), although girls were more likely to be passengers (P = .03). Facial contusions, lacerations, and abrasions were highly prevalent (62%, 69%, 65%, respectively), as were fractures of the facial bones and skull (77%). Thirty-five percent sustained closed head injuries, which were significantly associated with mandible fractures (odds ratio 12.8%; 95% CI, 1.15-143). Mean length of hospital stay was 4.6 +/- 5 days, and 36% required an ICU stay (mean, 5.1 +/- 3 days). Twenty-four percent required ventilator support (mean, 107 +/- 43 hours; range, 48 to 168 hours). Operative intervention was required in 72% of patients (n = 18). CONCLUSION: Maxillofacial injury patterns from ATV-related crashes in children suggest a high percentage of significant facial injuries and closed head injuries. As new ATV legislation that addresses operator use is enacted, a decrease in the number and severity of craniofacial injuries may be seen.

Variation in the human cervical neural canal.

BACKGROUND CONTEXT: The dimensions of the cervical spinal canal can impact the likelihood of an individual suffering longtime effects from a spinal neck injury as well as influence recovery time. Most studies have used radiographic studies to compare differences in the neural canal, but few have examined skeletal populations to determine variation in the neural canal dimensions without the presence of soft tissue. PURPOSE: To analyze variation seen in the cervical neural canal (anterior-posterior and transverse diameters) with respect to sex and ancestry and to define cervical canal narrowing in the sample. STUDY DESIGN: Observational. METHODS: Measurements of the anterior-posterior (sagittal) (CAP) and transverse (CTR) diameters were taken from 321 individual skeletons. Comparisons were made between males and females and individuals belonging to different ancestral (racial) groups. RESULTS: CAP was narrowest at the C4 level for African-Americans and at C6 for Caucasians. CTR was narrowest at the C2/C3 level for all groups. Statistical analyses indicated that significant differences in cervical canal dimensions are due first to sexual dimorphism and then to ancestry. CONCLUSIONS: Significant variation in cervical canal dimensions precludes usage of universal definitions to determine spinal stenosis in individuals; definitions should be according to sex and ancestry.

Patient satisfaction after carotid endarterectomy using a selective policy of local anesthesia.

BACKGROUND: Patient satisfaction after carotid endarterectomy has not been specifically studied or reported. Results of carotid endarterectomy using either local or general anesthesia have been widely reported, and outcomes are not significantly different for either technique. Patient satisfaction data were obtained in order to determine whether patients preferred one method of anesthesia over another. Data regarding outcome may be added to the surgical literature as benchmark data when comparing operative carotid endarterectomy to newer techniques. METHODS: During a 30-month period, 186 consecutive carotid endarterectomies were performed on 169 patients by a single surgeon with assistance from senior surgical residents. All patients were offered local anesthesia using a cervical block technique with intraoperative supplementation. Patients for whom local anesthesia was inappropriate or who declined were operated on using general endotracheal anesthesia. Results of operation were tabulated including indication for operation, method of anesthesia, intraoperative and postoperative complications, and mortality, and completion of a patient satisfaction survey form either on postoperative visit or by telephone questionnaire. RESULTS: Of 169 patients who underwent carotid endarterectomy, 151 (89%) completed the satisfaction survey form. One hundred fourteen (62%) had local anesthesia and 71 patients (38%) had general anesthesia. There was 1 stroke (0.5%) and 1 death (0.5%) in the series. Perioperative complications including temporary cranial nerve injury, neck hematoma, myocardial infarction, and restenosis were noted and not significantly different in either the general anesthesia or local anesthesia group. Patient satisfaction data including intraoperative discomfort, postoperative pain, attentiveness of the operating room staff, and length of stay were all tabulated. There was no statistically significant difference in satisfaction between the general anesthesia group and the local anesthesia group (chi-square and Fisher's exact test). Additionally, satisfaction with the procedure was extremely high. CONCLUSIONS: Patient outcome and perception of pain and recovery were not statistically significantly different in patients undergoing carotid endarterectomy using local anesthesia compared with general anesthesia. Overall patient satisfaction was extremely high. Patients should be offered carotid endarterectomy using an anesthesia technique with which the surgeon and patients are both comfortable, having confidence that the outcome is not related to anesthesia technique and that patients will be highly satisfied.

Vascular trauma.

The word "spasm" has been purposefully omitted as it is essentially a nonentity in vascular trauma. The surgeon's ability to repair and salvage extremities has increased greatly in the last 30 years. Problem areas still exist, especially in those patients with carotid trauma and neurologic deficit and patients with massive trauma to the extremities with involvement of bone, arteries, veins, nerves, and soft tissue. There is a place and a time for primary amputation, but its role in trauma surgery has definitely decreased and should continue to do so, as long as in so doing we do not jeopardize the life of the patient.

Trauma and fibromyalgia: is there an association and what does it mean?

OBJECTIVES: The primary objective is to review current research with respect to the role of trauma in fibromyalgia (FM). A secondary objective is to hypothesize which steps need to be taken, first to determine whether such an association truly exists, and second to clarify what such an association might mean. METHODS: An extensive literature review was undertaken, including Medline from 1979 to the present. RESULTS: The strongest evidence supporting an association between trauma and FM is a recently published Israeli study in which adults with neck injuries had greater than a 10-fold increased risk of developing FM within 1 year of their injury, compared with adults with lower extremity fractures (P= .001). Several other studies provide a hypothetical construct for such an association. These include studies on (1) postinjury sleep abnormalities; (2) local injury sites as a source of chronic distant regional pain; and (3) the concept of neuroplasticity. There are, however, several primary arguments against such an association: (1) FM may not be a distinct clinical entity; (2) FM may be a psychological, rather than physical, disease; (3) the evidence supporting any association is limited and not definitive; (4) the Israeli study, itself, has some methodological limitations; and (5) other factors may be more important than the injurious event in determining chronic symptoms after an acute injury. CONCLUSIONS: Although there is some evidence supporting an association between trauma and FM, the evidence is not definitive. Further prospective studies are needed to confirm this association and to identify whether trauma has a causal role.

Essentiality of the lateral cervical spine radiograph.

Proper interpretation of the lateral cervical spine (C-spine) film is a prime emergency medicine responsibility. Patients with potential neck injury must be identified rapidly and handled carefully; their C-spine films must be interpreted quickly and accurately. We stress the urgency in obtaining a good, readable lateral C-spine film and present a systemic "ABCs" approach to reading this film. This approach includes specific, sequential attention to Alignment, Bony integrity, Cartilaginous structures, and the surrounding Soft-tissue spaces. In the cases of 50 consecutive patients with C-spine injuries (49 adults, one child) seen recently in our emergency medicine program, we have correlated traumatic mechanisms with specific injury patterns. These analyses have been meshed with data from the patients' medical records and radiographs. In a significant number of instances (greater than 25% in this series), objective, careful radiographic interpretation is more important to the patient's objective, careful radiographic interpretation is more important to the patient's welfare than is any other diagnostic modality -- including history and physical examination.

Cricothyrotomy in the emergency department.

Thirty-eight emergency cricothyrotomies were performed over a 3-year period. This was the first airway control maneuver attempted in 5 patients, 3 of whom had facial and/or neck injury, one apneic with upper airway hemorrhage, and one with aortobronchial fistula. The remaining 33 procedures were performed only after other airway management failed. Five indications were identified among these cases: 1) excessive emesis or hemorrhage (11), 2) possible cervical spine injury with airway compromise (9), 3) technical failure (7), 4) clenched teeth (5), and 5) masseter spasm following succinylcholine administration (1). Fourteen immediate complications occurred in 12 patients (32%). The most frequent was incorrect site of tracheostomy tube placement (5), with 4 of 5 misplaced through the thyrohyoid membrane. Others included execution time greater than 3 minutes (4), unsuccessful tracheostomy tube placement (3), and significant hemorrhage (2). Twelve of the 38 patients were long-term survivors. There was one long-term complication, a longitudinal fracture of the thyroid cartilage during forceful placement of an oversized tube (8 mm inner diameter) through the cricothyroid membrane. This required operative repair and left the patient with severe dysphonia.

Cervical spine movement during orotracheal intubation.

We measured cervical spine movement during orotracheal intubation in 16 anesthetized patients without neck injury. Comparisons were made using straight and curved laryngoscope blades without stabilization, Philadelphia collar stabilization, and in-line stabilization by an assistant. There was cervical spine movement in all cases. There was no significant difference in movement without stabilization when comparing straight and curved laryngoscope blades (P = .8536). There was no significant decrease in movement when a Philadelphia collar was applied (P = 1.000). There was a significant decrease in movement when in-line stabilization was applied (P = 0.0056). Although none of the methods tested totally prevented cervical spine movement during orotracheal intubation, the least movement was obtained by the use of in-line stabilization by an assistant. The type of laryngoscope blade used or application of a Philadelphia collar did not reduce movement significantly.

Validity of the Dexter Evaluation System's Jamar dynamometer attachment for assessment of hand grip strength in a normal population.

There are several instruments available to measure grip strength, but some instruments are costly, time-consuming to use, or have questionable reliability. The purpose of this study is to examine the concurrent validity of the Dexter Evaluation System with Jamar dynamometer attachment (Dexter) compared with the reference-based criterion of the Jamar adjustable hand dynamometer (Jamar) for measurement of maximal hand grip strength among normal subjects. Sixty-two subjects between the ages of 20 and 50 years, who had no history of hand, arm, shoulder, or neck injuries, were tested with the Jamar in the second handle position and, during the same visit, with the Dexter in the identical position. The Jamar was found to be highly reliable (ICC [3,1] = 0.98) and valid (ICC (2,K) = 0.99) for measuring hand grip strength. In this study, the Dexter was shown to be valid when compared to the Jamar dynamometer for measuring hand grip strength.

Long term results of diaphragmatic plication for unilateral diaphragm paralysis.

OBJECTIVES: To examine whether diaphragmatic plication is an effective and lasting treatment option for non-malignant diaphragmatic paralysis. METHODS: Nineteen patients who had undergone diaphragm plication (1983-1990) were recalled for interview, pulmonary function testing and chest X-ray. RESULTS: There were 13 men and six women aged 24-73 (mean 55). Diaphragm paralysis was idiopathic (n=9), postsurgical (n=3), related to cervical spondylosis (n=4) and neck injury (n=2). Patients presented with breathlessness (18/19) or orthopnoea (1/19). Symptoms had lasted 3-60 months (mean 24 months). All patients had a raised hemidiaphragm on chest X-ray with paradoxical movement on ultrasound. Mean preoperative FVC was 71% predicted (range 38-93, SD 12.9) and mean FEV(1) was 67% predicted (range 33-90, SD 10.8). Supine lung volumes were 81% (mean) of sitting values. There were six right plications and 13 left. There were no postoperative deaths. One patient required re-plication. Follow-up (18/19 of original operated patients) ranged from 7-14 years (mean 10 years). Three patients had died of unrelated causes and one patient failed to attend long term follow-up, leaving 15 patients of the original 19 operated on. Positional change in lung volumes was not affected by surgery at early (6 week) or late (>5 year) follow-up. FVC, FEV(1), FRC and TLC improved by 10.1*, 11.8*, 16.9* and 9.2*%, respectively, at early follow-up and 11.8*, 15.4*, 26 and 13.3*% at late follow-up (*P<0.005 signed rank). Dyspnoea scores at long term follow-up improved 1 point (n=5), 2 points (n=5) and 3 points (n=2), remained unchanged (n=1) or dropped 1 point (n=2). Of the 15 patients followed up all but one who had been employed returned to work. 14/15 patients expressed satisfaction with their surgery. CONCLUSION: Diaphragm plication is an effective procedure with lasting results.

Use of the electrothermal vessel sealing system versus standard vessel ligation in thyroidectomy.

OBJECTIVE: The electrothermal vessel sealing system (LigaSure) facilitates operative haemostasis by fusing blood vessel walls to form a collagen seal. The LigaSure is currently used in a variety of gastrointestinal, gynaecological and urological operations. We report our experience with LigaSure for thyroidectomy to test the hypothesis that it reduces operating time without increasing complications compared with standard vessel ligation. METHODS: This non-randomized, retrospective review included 234 consecutive patients who underwent thyroidectomy by one surgeon. Standard vessel ligation was used in 99 patients between 1997 and 2000, and the LigaSure was used in 135 patients between 2001 and 2003. The following data were collected: patient demographics, thyroid pathology, type of operation (total thyroidectomy vs lobectomy), operating time, complications (transient or permanent hypocalcaemia, <or=8 mg/dL), recurrent or superior laryngeal nerve injury, neck haematoma, wound complications, prolonged intubation), incision length and hospital stay. RESULTS: The two groups had similar demographics, thyroid pathology, types of operations and complication rates. The LigaSure group had lower operating times and incision lengths. CONCLUSION: We found that the LigaSure was as safe as standard vessel ligation for thyroidectomy, with the benefit of reduced operating time. A future prospective study has been designed.

A case of strangulation by a vehicle seat belt.

A healthy 23-year-old man wearing a three-point seat belt suffered from a roll-over traffic accident. When the man was found, the fastened seat belt had loosened and the diagonal belt was tightened against the neck. Autopsy findings revealed ligature marks on the surface of the neck, hemorrhages in the muscles of the neck, petechial hemorrhages in palpebral conjunctivae and viscera, dark red liquid blood in the heart cavities and visceral congestion. We concluded that the man died of strangulation by the seat belt. In this case, the loose belt allowed the body to move and subsequently the diagonal belt applied external pressure to the neck while the car was rolling over. Although there have been several reports of neck injuries due to diagonal belts, this is the first report of strangulation by a properly used three-point belt in a roll-over vehicle accident.
