Hemipelvectomy as a Salvage Procedure in Massive Pelvic Trauma.

"Pedestrian struck by train" represents one of the highest magnitude blunt force traumas. Despite the severity of injuries, these patients can have good outcomes. A 25-year-old male presented after being struck by a train. He had several injuries, including extensive complex pelvic fractures, right external iliac artery and vein laceration, and right femur and tibia fracture. He was taken to the operating room for damage control surgery and attempted revascularization of the right lower extremity. The extremity became ischemic and required above knee amputation followed by hip disarticulation and hemipelvectomy. His pelvic wounds were treated with negative pressure wound therapy and gradually closed. He was eventually discharged to a rehab facility for continued recovery. This case highlights the interventions that allowed a young man who was struck by a train to survive. He improved significantly since undergoing hemipelvectomy, indicating that severe pelvic injuries from high energy trauma may necessitate hemipelvectomy.

Jejuno-jejunal intussusception secondary to recurrent/metastatic melanoma.

Intussusception is uncommon in adults, and usually secondary to a neoplasm. Small bowel obstruction (SBO) is prevalent in adults but rarely due to intussusception. A 55-year-old woman with history of melanoma (four years in remission) presented with abdominal pain and melena. Upper and lower endoscopy was normal. She developed bilious emesis and worsening pain, so she presented to the emergency department. CT abdomen/pelvis identified a SBO with transition point at a small bowel intussusception; she was taken to the operating room. A mid-jejunal intussusception was reduced revealing a mass; resection and primary anastomosis was performed. Final pathology demonstrated a 5.5 cm melanoma, likely metastatic. She required no additional therapy and remains in remission eighteen months later. Intussusception due to metastatic melanoma is rare but should be on the differential for patients with SBO and history of melanoma. Knowledge of this history should prompt consideration for oncologic resection to optimize outcome.

Cerebral Fat Embolism via a Patent Foramen Ovale.

Fat embolism syndrome (FES) is a multisystem process predominantly secondary to long bone/pelvic fractures and orthopedic procedures. A 19-year-old man presents after motor vehicle collision with trace right pneumothorax, right grade 3 kidney laceration, left pubic rami, and right femoral shaft fractures. Right femur closed reduction ensued and he underwent intramedullary nailing; his other injuries were managed nonoperatively. Upon awakening in recovery, he was newly aphasic. Despite negative repeat CT brain, he continued to worsen and became tachycardic and hypoxemic. MRI/MRA brain demonstrated innumerable bilateral frontal, parietal, and occipital acute ischemic infarcts in a starfield pattern. Echocardiogram revealed a PFO. With supportive care, he improved and was discharged with planned outpatient PFO closure. One month later, he had complete symptom resolution with return to neurologic baseline. FES is a potentially devastating condition which may include cerebral fat embolism (CFE) with outcomes varying widely from mortality to complete recovery.

Clinical Diagnosis of Infection in Surgical Intensive Care Unit: You're Not as Good as You Think!

Background: Because of the everincreasing costs and the complexity of institutional medical reimbursement policies, the necessity for extensive laboratory work-up of potentially infected patients has come into question. We hypothesized that intensivists are able to differentiate between infected and non-infected patients clinically, without the need to pan-culture, and are able to identify the location of the infection clinically in order to administer timely and appropriate treatment. Methods: Data collected prospectively on critically ill patients suspected of having an infection in the surgical intensive care unit (SICU) was obtained over a six-month period in a single tertiary academic medical center. Objective evidence of infection derived from laboratory or imaging data was compared with the subjective answers of the three most senior physicians' clinical diagnoses. Results: Thirty-nine critically ill surgical patients received 52 work-ups for suspected infections on the basis of signs and symptoms (e.g., fever, altered mental status). Thirty patients were found to be infected. Clinical diagnosis differentiated infected and non-infected patients with only 61.5% accuracy (sensitivity 60.3%; specificity 64.4%; p = 0.0049). Concordance between physicians was poor (κ = 0.33). Providers were able to predict the infectious source correctly only 60% of the time. Utilization of culture/objective data and SICU antibiotic protocols led to overall 78% appropriate initiation of antibiotics compared with 48% when treatment was based on clinical evaluation alone. Conclusion: Clinical diagnosis of infection is difficult, inaccurate, and unreliable in the absence of culture and sensitivity data. Infection suspected on the basis of signs and symptoms should be confirmed via objective and thorough work-up.

Investigating Clinical and Cost Burdens of Law Enforcement-Related K9 Injuries: The Impact of "the Bite" on a Community Hospital.

The decision to introduce canines (K9s) to a law enforcement (LE) agency does not typically involve the evaluation of the fiscal or clinical impact on local hospitals. This study compared injury, cost, and care associated with K9s to a common nonlethal force method, the Thomas A Swift Electrical Rifle (TASER), to highlight the cost and resources required to treat both patient types. Patients treated for LE-related K9 and TASER injuries at a Level I community-based trauma center (2011-2016) were evaluated for level of care required (e.g., surgeon/specialist), clinical interventions, proxy medical costs, and length of stay (LOS). Nearly one-third of K9 patients required tertiary-level medical care. The cost of treating the K9-inflicted injuries (n = 75) was almost twice as costly as care for patients subdued with a TASER (n = 80); the K9 patients had significantly (one-tailed t tests) higher medical costs (P = 0.036), required more medical procedures (P = 0.014), and had longer LOS (P = 0.0046) than the TASER patients. Patients with K9 injuries had higher acuity and were significantly more expensive to treat with longer LOS than TASER injuries. LE agencies considering establishing and operating a K9 unit should initiate discussions with their local medical first responders and health-care facilities regarding the capabilities to treat severe K9 injuries to ensure adequate resource allocation.

Necrotizing Fasciitis Resulting from an Anastomotic Leak after Colorectal Resection.

One of the most feared complications in colorectal surgery is an anastomotic leak (AL) following a colorectal resection. While various recommendations have been proposed to prevent this potentially fatal complication, anastomotic leaks still occur. We present a case of an AL resulting in a complicated and fatal outcome. This case demonstrates the importance of high clinical suspicion, early recognition, and immediate management.

Inclusion of the Acute Care Surgeon in the Difficult Airway Protocol: A Nine-Year Experience.

An emergency surgical airway is a lifesaving intervention required in the event of airway loss or respiratory failure when conventional endotracheal intubation cannot be performed. The Acute Care Surgery/Trauma Service is a critical component in the angioedema/difficult airway protocol at our institution. We conducted a retrospective review (2007-2016) to analyze the role our service has in managing patients requiring an emergency surgical airway. Cases were analyzed for preexisting conditions, hospital location of procedure, techniques, complications, and mortality. Our protocol involves early coordination between anesthesia and the Acute Care Surgery/Trauma Service for patients with a potentially difficult airway. If anesthesia is unable to intubate the patient, a surgical airway is performed. Patients are preemptively taken to the operating room (OR) if stable for transport. There were 43 surgical airways performed during the study period. All patients had a failed attempt with oral endotracheal intubation. The most common factors associated with these patients were history of tracheostomy, angioedema, or difficult anatomy. Nineteen (44%) of the surgical airways were performed in the OR. Three deaths (7%) occurred from cardiac or respiratory arrest despite the emergency procedure. No immediate deaths occurred in the patients taken to the OR. Early coordination in patients with a difficult airway is another hospital resource that the acute care surgeon can provide to improve patient outcomes.

Intraoperative rescue extracorporeal membrane oxygenation and damage control during repair of a traumatic aortic injury.

A 21-year-old male involved in a motorcycle crash presented with abdominal hemorrhage and a widened mediastinum on chest radiograph. He required an initial exploratory laparotomy for mesenteric injuries. An aortic injury was confirmed on computed tomography imaging and he subsequently underwent attempted endovascular repair. During that procedure, the patient experienced massive thoracic hemorrhage with cardiac arrest and profound respiratory failure. Damage-control thoracic surgery and rescue extracorporeal membrane oxygenation were successfully utilized with a favorable outcome.

Delayed Stroke following Blunt Neck Trauma: A Case Illustration with Recommendations for Diagnosis and Treatment.

Blunt cerebrovascular injury (BCVI) to the carotid artery is a relatively rare injury that is difficult to identify even with imaging. Any symptoms or neurological deficits following blunt neck injury mandate evaluation and consideration of BCVI. In an effort to highlight this issue, we report the case of a 31-year-old male patient who presented with left-sided weakness consistent with transient ischemic attack (TIA) and concussion. The patient's symptoms occurred within 24 hours of a blunt neck injury sustained by a knee strike during a basketball game. An initial computerized tomography (CT) scan of the brain was normal; a CT angiogram (CTA) of the neck and carotids did not reveal obstruction, dissection, stenosis, or abnormalities of the carotid or vertebral vessels and the patient was subsequently discharged. A magnetic resonance imaging (MRI) of the brain obtained four days after the initial injury demonstrated an acute infarct in the right middle cerebral artery (MCA) territory. Thus, despite initial negative imaging, neurological deficits must be aggressively pursued in order to prevent stroke in BCVI cases.

Duplicate Vas Deferens Encountered during Inguinal Hernia Repair: A Case Report and Literature Review.

Duplication of the vas deferens is a rare anomaly, defined as the presence of two distinct vasa deferentia within one spermatic cord, with only 28 cases reported worldwide since 1959. We report the case of a 63-year-old man with a duplicate vas deferens, presenting with abdominal pain from bowel obstruction secondary to incarcerated inguinal hernia. Spermatic cord dissection during hernioplasty revealed duplication of the vas deferens within the right spermatic cord. Doppler ultrasonography confirmed absence of waveforms in both vasa deferentia with arterial signal in the accompanying vessel. The hernia was repaired without complication. This report emphasizes recognition of duplicate vas deferens in avoiding iatrogenic injury and optimizing surgical outcome.

Congenital Renal Fusion and Ectopia in the Trauma Patient.

We present two separate cases of young male patients with congenital kidney anomalies (horseshoe and crossed fused renal ectopia) identified following blunt abdominal trauma. Despite being rare, ectopic and fusion anomalies of the kidneys are occasionally noted in a trauma patient during imaging or upon exploration of the abdomen. Incidental renal findings may influence the management of traumatic injuries to preserve and protect the patient's renal function. Renal anomalies may be asymptomatic or present with hematuria, flank or abdominal pain, hypotension, or shock, even following minor blunt trauma or low velocity impact. It is important for the trauma clinician to recognize that this group of congenital anomalies may contribute to unusual symptoms such as gross hematuria after minor trauma, are readily identifiable during CT imaging, and may affect operative management. These patients should be informed of their anatomical findings and encouraged to return for long-term follow-up.

Traumatic Lung Herniation following Skateboard Fall.

Lung herniation (LH) is a rare clinical entity involving the protrusion of lung outside the thoracic cage. It has a variety of etiologies and clinical presentations, making diagnosis difficult. We present a case of a 20-year-old male who reported pleuritic pain after falling from a skateboard. Evaluation through computed tomography (CT) scanning of the chest revealed an anterior lung hernia associated with rib fractures. This case emphasizes the need for clinicians to include lung herniation in the differential diagnosis of patients with trauma and inexplicable or persistent pulmonary issues.

Medical and Surgical Management of Postpartum Hemorrhage in a Woman with Factor XIII Deficiency.

Factor XIII deficiency is a rare inherited coagulopathy. Factor XIII is the last clotting factor in the coagulation cascade to insure strength and stability to fibrin clots. Without this enzyme, the fibrous clot is unstable and nonresistant to fibrinolysis. Gravid women with this congenital disease are especially at risk for complications including miscarriages and hemorrhage without appropriate interventions. We present a case of a woman in her 20s with Factor XIII deficiency who was treated with cryoprecipitate and had a successful normal spontaneous vaginal delivery; subsequently, patient suffered from postpartum hemorrhage and consumptive coagulopathy due to consumption of Factor XIII, requiring emergency surgical intervention. Intraoperative management was challenged by an ethical dilemma involving the patient's religious beliefs about not receiving blood. This paper will discuss the mechanism of Factor XIII and the medical and surgical management involved with this patient.

A unique case of venous air embolus with survival.

Venous air embolus (VAE) occurs when gas, specifically atmospheric air, enters into the vascular system. Although rare, they can be fatal due to risk of cardiovascular collapse. In this report, we present a unique case of a 66-year-old female trauma patient with an inferior vena cava air embolism. An overview of the potential cause is presented, along with a review of the management of VAE.
