A unique case of Lemierre's syndrome status post blunt cervical trauma.

BACKGROUND: Lemierre's syndrome is a rare but potentially fatal condition. The course is characterized by acute tonsillopharyngitis, bacteremia, internal jugular vein thrombosis, and septic embolization. There have been some cases secondary to penetrating trauma to the neck. Literature review has yielded no cases secondary to blunt neck trauma in the absence of oropharyngeal injury. We aim to shed light on this unique cause of Lemierre's syndrome, so as to raise the index of suspicion for clinicians working up patients with blunt cervical trauma. METHODS: We present a case of a 25-year-old male restrained driver who presented with left neck and shoulder pain with a superficial abrasion to the left neck from the seatbelt who was discharged same day by the Emergency Room physicians. He returned to the Emergency Department two days later with abdominal pain. As a part of his repeat evaluation, a set of blood cultures were sent and was sent home that day. The patient was called back to the hospital one day later as preliminary blood cultures were positive for Gram positive cocci and Gram negative anaerobes. Computerized tomography scan of the neck revealed extensive occlusive left internal jugular vein thrombosis and fluid collections concerning for abscesses, concerning for septic thrombophlebitis. The patient continued to decompensate, developing severe sepsis complicated by disseminated intravascular coagulation. RESULTS: The patient underwent a left neck exploration with en bloc resection of the left internal jugular vein, drainage of abscesses deep to the sternocleidomastoid, and washout/debridement of necrotic tissue. Direct laryngoscopy at the time of surgery revealed no injury to the aerodigestive tract. Wound cultures were consistent with blood cultures and grew Fusobacterium necrophorum, Staphylococcus epidermidis, and Methicillin-resistant staphylococcus aureus. The patient underwent two subsequent operative wound explorations without any evidence of residual infection. The patient was discharged home on postoperative day 13 on a course of antibiotics and aspirin. CONCLUSION: This case illustrates the importance of diagnosis of Lemierre's syndrome after an unconventional inciting event (blunt cervical trauma) and appropriate treatment.

Novel endovascular techniques for repair of traumatic bilateral axillary artery disruption with long-term follow-up.

We describe a case of innovative endovascular techniques to repair traumatic bilateral axillary artery disruption. A 36-year-old male construction worker fell eight stories from a scaffold and sustained bilateral axillary artery injuries. The injuries between the brachial and axillary arteries were bridged using long bare self-expanding stents (Zilver). To the best of our knowledge, this is a novel case report from a level-one trauma center where endovascular techniques were employed to repair bilateral axillary arteries with long-term follow-up.

Postcarotid endarterectomy pseudoaneurysm treated with combined stent graft and coil embolization--a case report.

Pseudoaneurysm formation is a rare complication following carotid endarterectomy (CEA); however, its occurrence is associated with significant risk of morbidity. The patient in this report presented 2 years following CEA with headache and lateral neck mass. The diagnosis of a 3.5 x 3.0 cm carotid artery bifurcation pseudoaneurysm was made by using magnetic resonance angiography (MRA). Endovascular exclusion of the aneurysm was accomplished with coil embolization of the external carotid artery followed by deployment of a 7 x 50 mm wall stent graft into the common carotid artery-internal carotid artery (CCA-ICA). The patient's symptoms improved and at 6-months postexclusion, duplex ultrasound demonstrated a significant reduction in pseudoaneurysm size. This case highlights the feasibility and safety of using endovascular techniques in the treatment of post-CEA pseudoaneurysm.

Is carotid angioplasty and stenting more cost effective than carotid endarterectomy?

OBJECTIVE: Carotid angioplasty and stenting (CAS) has been advocated as a minimally invasive and inexpensive alternative to carotid endarterectomy (CEA). However, a precise comparative analysis of the immediate and long-term costs associated with these two procedures has not been performed. To accomplish this, a Markov decision analysis model was created to evaluate the relative cost effectiveness of these two interventions. METHODS: Procedural morbidity/mortality rate for CEA and costs (not charges) were derived from a retrospective review of consecutive patients treated at New York Presbyterian Hospital/Cornell (n = 447). Data for CAS were obtained from the literature. We incorporated into this model both the immediate procedural costs and the long-term cost of morbidities, such as stroke (major stroke in the first year = $52,019; in subsequent years = $27,336/y; minor stroke = $9419). We determined long-term survival rate in quality-adjusted life years and lifetime costs for a hypothetic cohort of 70-year-old patients undergoing either CEA or CAS. Our measure of outcome was the cost-effectiveness ratio. RESULTS: The immediate procedural costs of CEA and CAS were $7871 and $10,133 respectively. We assumed major plus minor stroke rates for CEA and CAS of 0.9% and 5%, respectively. We assumed a 30-day mortality rate of 0% for CEA and 1.2% for CAS. In our base case analysis, CEA was cost saving (lifetime savings = $7017/patient; increase in quality-adjusted life years saved = 0.16). Sensitivity analysis revealed major stroke and death rates as the major contributors to this differential in cost effectiveness. Procedural costs were less important, and minor stroke rates were least important. CAS became cost effective only if its major stroke and mortality rates were made equivalent to those of CEA. CONCLUSION: CEA is cost saving compared with CAS. This is related to the higher rate of stroke with CAS and the high cost of stents and protection devices. To be economically competitive, the mortality and major stroke rates of CAS must be at least equivalent if not less than those of CEA.
