Objective:
Tracheostomy is a necessary procedure for patients admitted to the neurosurgery intensive care unit (ICU) with severe brain injury, because mechanical ventilation must be maintained for a long time following neurologic failure. The purpose of this study was to compare conventional surgical tracheostomy (CST) and percutaneous dilatational tracheostomy (PDT) performed at the bedside in critically ill neurosurgery patients requiring tracheostomy to determine which procedure has comparative advantages.
Methods:
This retprospective study was conducted between January 2019 and December 2020. PDT was performed on 52 patients and CST was performed on 44 patients. The baseline characteristics, procedural characteristics, and clinical outcomes were recorded.
Results:
The mean operative time in the CST group was 25.5±6.5 minutes and that in the PDT group was 15.1±2.5 minutes; the difference was statistically significant (p<0.01). Four patients in the CST group and none in the PDT group experienced bleeding requiring transfusion. However, there was no significant difference in total ICU mortality or length of hospital stay. There were no statistical differences in the individual complication categories between the 2 study groups.
Conclusion
There were fewer procedure-induced complications among patients receiving PDT than among those receiving CST. In addition, the treatment time for PDT was shorter than that for CST treatment.

Persistent primitive trigeminal artery (PPTA) is the most common carotid-basilar anastomosis; on the other hand, persistent primitive otic artery (PPOA) is extremely rare. PPTA is often misdiagnosed as PPOA on cerebral angiography. We present a case of PPTA that mimicked PPOA on cerebral angiography. We further describe the utility of brain computed tomography angiography for differential diagnosis of PPTA from PPOA, together with a review of previous literature.

This study was performed to radiographically examine the prevalence of aspiration sites and to evaluate their atomical correlation with the bronchial pattens. Ten healthy beagle dogs were repeatedly radiographed, at weekly intervals, in the left and right lateral, ventrodorsal (VD) and dorsoventral (DV) positions. Three mililiters of iohexol distilled with same volume of saline was infused into the tracheal inlet. Which lung lobe was aspirated was decided upon by the presence of a significant alveolar pattern due to the contrast medium. Alveolar patterns were identified at the left (100%) and right cranial lung lobes (77%) with the dogs in dependant lateral recumbency, at the right caudal lung lobe (71%) with the dogs in VD recumbency and at the right middle lung lobe (59%) with the dogs in DV recumbency, respectively. The anatomical correlation was evaluated by performing computed tomography. The right principal bronchus (165.8 +/- 1.6 degrees) was more straightly bifurcated than was the left principal bronchus (142.7 +/- 1.8 degrees, p < 0.01). In VD position, the right side lung had a greater opertunity to become aspirated. The ventrally positioned right middle lobar bronchial origin was more easily to be aspirated the other laterally positioned ones. We think that these anatomical characteristics can be one of the causes for aspiration pneumonia to occur more frequently in the right side lung.

Lateral spinal artery (LSA) aneurysms are extremely rare lesions that can rupture and cause subarachnoid hemorrhage (SAH) even though the spinal arteries communicate directly with the subarachnoid space. To date, six cases of LSA aneurysms have been reported in the literature. Herein, three such cases are reported. All patients presented to the emergency department with headaches. The patients in the first two cases were confirmed to have SAH and LSA aneurysms on a brain computed tomography (CT) angiography performed at the hospital. Two patients had prior instances of cerebral infarction and coronary disease, respectively, and were undergoing antiplatelet therapy. The antiplatelet medication was stopped for 2 weeks and 1 week, respectively, while conservative care was provided. Subsequently, a suboccipital craniectomy was performed, followed by aneurysm clipping. Following the surgery, both patients were discharged without any significant neurological deficits. Regarding the third patient, no aneurysm was found on brain CT angiography, and cerebral angiography was performed during the patient’s hospital stay. She was hospitalized, where she received medication and conservative care, and was discharged with an improvement in bleeding without neurological symptoms. Subsequently, a LSA aneurysm was identified on a brain CT angiography performed at an outpatient clinic; however, the patient was transferred because she wanted to be treated at another hospital. LSA aneurysms are difficult to visualize using CT angiography; therefore, careful angiographic studies are required. Surgical clipping is the treatment of choice if the aneurysm is inaccessible by the endovascular treatment.

PURPOSE: Divided end-loop colostomy is recommended in some cases of unresectable rectal cancer or anal incontinence, because a conventional loop colostomy is difficult to managing due to bulky stoma volume for a long period. In such case of the divided end-loop colostomy, severe inflammation may occur at the stoma site by poor conditions of the patient so that cause to be retracted or detached, and distal loop may be disrupted. To avoid these problems, we designed subtotally divided end-loop colostomy and studied its clinical effectiveness retrospectively. METHODS: About a 3 cm diameter, round skin incision as presumed colostomy size was made at the left lower abdomen, and entered the abdominal cavity by splitting the rectus muscle fibers. The caudal side of colon can be identified by confirming the fusioned taenia at the rectosigmoid colon level. After pulling out the colonic loop, the distal colon far from the lesion was subtotally divided by a GIA staple or manual suture, which cut obliquely 80% or 90% from the antimesenteric side of the distal loop while maintaining the 10% or 20% mesenteric side of the colonic loop. Then an end-loop colostomy is matured with a small fistularization of the distal loop as the undivided mesenteric side of colon. RESULTS: In 8 cases, subtotally divided colonic loop using a GIA staple. But in 9 cases, divided manually because of makedly thickened, edematous colonic wall resulting from prolonged obstruction. There were several mild complications, i.e. transient dermatitis in 5 cases, transient bulky stoma due to edema in 4 cases, mild retraction of stoma in 2 cases, and mild prolapse of stoma in 1 case. There were no major functional abnormalities during the follow-up period. CONCLUSIONS: Although we need to get further clinical experiences, the subtotally divided end-loop colostomy seems to be a useful alternative surgical procedure for unresectable rectal cancer.

PURPOSE: Fever is one of the most common symptoms in children visiting the emergency department. When oral antipyretics use is limited, IV antipyretics may be necessary for control of fever. In this study, we examined the current status of use and antipyretic effect of propacetamol, a precursor of acetaminophen, in fever management for children of age younger than 15 in an emergency center. METHODS: We reviewed medical records of 101 patients who were prescribed IV propacetamol from September 1st to December 31st in 2013. Among these patients, 59 children received propacetamol via intravenous injection for control of fever. We investigated variable data including age, sex, weight, chief complaint, reason for use of intravenous propacetamol, history of liver disease, and body temperature before the injection. In addition, to examine the antipyretic efficacy of IV propacetamol, we thoroughly investigated administration dose, number of injections, use of other antipyretics, other antipyretic therapy (ex. like tepid massage or ice bag), fever clearance time, etc. RESULTS: Intravenous propacetamol at a dose of 26.16 mg/kg was used in 59 patients and fever was controlled under 38degrees C within 2 hours in 39 patients (66.1%). Fever was relieved under 38degrees C within 4 hours or general condition was improved in 49 patients (83.0%). CONCLUSION: In this study, we examined the antipyretic efficacy of intravenous propacetamol in management of fever for children younger than 15 years of age in an emergency center. Optimized uses of intravenous propacetamol according to age and weight were effective for pediatric patients with fever who cannot swallow oral medications.
