Decompressive Hemicraniectomies as a Damage Control Approach for Multilobar Firearm Projectile Injuries: A Single-Center Experience.

BACKGROUND: While firearms projectile injuries to the head carry a high rate of morbidity and mortality, current literature in clinical management remains controversial. Decompressive hemicraniectomy (DHC) has been previously described in the neurosurgical literature for traumatic brain injuries, with positive results in the reduction of mortality. Here we aim to assess DHC as a damage control approach for multilobar firearm injuries to the head and compare our results with what is present in the literature. METHODS: A retrospective review of patients who sustained multilobar firearm injuries to the head admitted to our center from January 2009 to April 2021 was performed. Exclusion criteria were a Glasgow Coma Scale (GCS) score <5, and/or brain stem dysfunction that persisted despite stabilization and medical therapy for intracranial hypertension. RESULTS: A total of 20 patients were analyzed, with an average GCS on admission of 8.35. The 60-day mortality rate for all 20 patients was 20% with a total of 4 deaths, 1 of which was due to pulmonary sepsis in the critical postoperative care unit. The mean hospital stay of surviving patients was 22 days. CONCLUSIONS: DHC should be considered as a damage control strategy for young patients with multilobar firearm injuries and GCS >5, having yielded favorable results in this study when compared to current literature.

Minimally invasive keyhole supraorbital craniotomy as treatment option for penetrating foreign body through orbital roof.

Intraorbital foreign body is a rare condition, especially when extending into the intracranial compartment. When facing this scenario in the ER, the neurosurgeon must carefully choose the optimal point of surgical access in order to reduce morbidity. The authors hereby report the case of a 66 year-old male with a penetrating trauma to the orbit reaching the anterior cranial base through the orbital roof and associated with an intracerebral hematoma. The removal of the foreign body was performed by a dual approach: an 'eyebrow' supraorbital keyhole craniotomy and an intra-orbital extra-ocular exploration, with later microsurgical drainage of the hematoma and evisceration of the eye 48 hours later. The patient developed a pseudomeningocele, which was treated with lumbar puncture and compressive dressing. After proper intravenous antibiotic prophylaxis, the patient was discharged 21 days after hospital admission.

Acute Hydrocephalus Following a Spontaneous Ventriculoperitoneal Shunt Catheter Fracture With Scrotal Migration.

Genitalia-related complications of ventriculoperitoneal shunts, such as scrotal migrations, are rare and most frequently presenting during the first year of the system placement, usually in the pediatric population, due to several factors, including vaginal process patency and increased abdominal pressure. Despite being typically benign, hernias, hydroceles, perforations, and catheter migration to the scrotum can lead to permanent disabilities and lethal complications, such as ventriculoperitoneal shunt dysfunction. We report a case of a late-onset, atraumatic, ventriculoperitoneal shunt fracture and catheter migration to the scrotum in a 22-year-old male, six years after its implantation, presenting in the emergency department due to acute hydrocephalus symptoms.

Inadequate request of transthoracic echocardiography according to the guidelines of the Brazilian Society of Cardiology.

BACKGROUND: Guidelines from medical societies suggest recommendations for the appropriate request of tests. In 2009, the Brazilian Society of Cardiology (BSC) published new guidelines for transthoracic echocardiography (TTE) request. OBJECTIVE: To evaluate the prevalence of Class III requests for TTE, as defined by the BSC Guidelines and analyze these requests profile comparing a public university hospital (PUH) with a private cardiology hospital (PCH). METHODS: We prospectively evaluated 779 consecutive outpatient TTE requests: 391 from the PCH and 388 from the PUH between December 2009 and May 2010. The indications studied were classified accordingly to the BSC guidelines. Request distribution was compared by Chi-square test. Statistical significance was set at p < 0.05. RESULTS: Of the 779 requests, 61 (7.8%) were considered Class III. Of these 14 were from the public and 47 from the private hospital. The distribution of requests was statistically different between institutions (p < 0.001). Check-up in asymptomatic patients was the main inadequate indication, with 37 cases (33 in the private institution- 89.18%), followed by evaluation after angioplasty in 9 cases (8 in the private institution - 88.88%); ventricular function monitoring in patients with stable heart failure in 6 cases (4 in the public institution - 66.66%), post-bypass surgery in 5 cases (4 in the private institution- 80%), and evaluation of nonspecific electrocardiographic abnormalities in 4 cases (4 in the public institution - 100%). CONCLUSION: Asymptomatic patients' assessment was the main cause of inadequate TTE requests, which differs between institutions: routine check-up in the private and heart failure in the public hospital.
