Importance: A modified percutaneous dilational tracheostomy (PDT) is a relatively new alternative method of performing PDTs in which tissues overlying the trachea are dissected, but needle entry is still performed blindly. Many centers use bronchoscopy-assisted PDT, but the necessity of bronchoscope assistance for modified PDTs has not been examined. Discontinuing bronchoscopy for this procedure could potentially decrease cost and increase efficiency with similar outcomes compared with bronchoscopy-assisted PDT.
Objective: To evaluate the necessity of bronchoscopy in placement of PDT.
Design, Setting, And Participants: A single-center, retrospective cohort study of 149 patients who underwent PDT, with or without bronchoscope assistance, was conducted between May 1, 2007, and February 1, 2015, in a tertiary care facility. Data analysis was performed from April 15, 2015, to May 1, 2015.
Interventions: Modified PDT with or without bronchoscopy.
Main Outcomes And Measures: The primary outcomes of interest were postprocedural complications and length of stay during the hospitalization at which the tracheostomy was placed.
Results: Of the 149 patients who underwent modified PDT during the study period and met the inclusion criteria, 107 were in the no-bronchoscope cohort (66 [61.7%] were men; mean [SD] age, 56.0 [18.7] years) and 42 were in the bronchoscope-assisted cohort (26 [61.9%] were men; mean [SD] age, 58.0 [15.7] years). Complications with PDT were significantly associated with use of a bronchoscope (odds ratio, 6.7; 95% CI, 1.3-43.4; P = .04). The rate of complications was 1.9% in the no-bronchoscope cohort and 11.9% in the bronchoscope-assisted cohort (P = .05). The mean (SD) length of hospital stay was not significantly different between the 2 groups (51.4 [49.4] days in the no-bronchoscope cohort vs 46.9 [28.6] days in the bronchoscope-assisted cohort; P = .58).
Conclusions And Relevance: Percutaneous dilational tracheostomy can be performed with similarly low complication rates with or without the use of bronchoscopy. Discontinuing the use of bronchoscopy in these procedures appears to be a safe, cost-effective alternative with reassuring outcomes and low complication rates.

Objective: This study aimed to examine the effect of drug-coated balloons (DCBs) on vascular luminal dilatational remodeling (VLDR) following simple balloon angioplasty.
Methods: A retrospective cohort study was conducted using data from patients diagnosed with intracranial atherosclerotic stenosis (ICAS), who were treated exclusively with balloon angioplasty at Henan Provincial People's Hospital between June 2019 and April 2023. Inverse probability weighting (IPW) was used to create balanced cohorts of patients who underwent drug-coated balloon angioplasty (DCBA) and plain old balloon angioplasty (POBA).
Epidemiology, timing, technique, and outcomes of tracheostomy in patients with trauma: a multi-centre retrospective study.

Background: Tracheostomy is performed in patients with trauma who need prolonged ventilation for respiratory failure or airway management. Although it has benefits, such as reduced sedation and easier care, it also has risks. This study explored the unclear timing, technique, and patient selection criteria for tracheostomy in patients with trauma.

Article Synopsis
- Percutaneous dilational tracheostomy (PDT) is often favored for critically ill patients, particularly when using rigid bronchoscopy guidance, which enhances airway safety and ventilation.
- A study of 104 patients from 2008 to 2023 at Beth Israel Deaconess Medical Center revealed that many had risk factors like high BMI and prolonged mechanical ventilation, but the procedure was generally safe with no significant complications.
- The findings suggest that RBG-PDT can be effectively performed by skilled Interventional Pulmonologists, broadening the scope of patients who can benefit from this procedure.

Background: Detailed reports are scarce on minimally-invasive tracheostomy (MIT) techniques for critically ill patients with challenging anatomy or complex coagulopathies. In such high-risk patients, conventional percutaneous dilatational tracheostomy (PDT) may lead to severe complications.
Methods: Aiming to broaden the scope of MIT for patients previously excluded due to high risks, we developed a new care bundle (MIT technique), specifically designed for intensive care specialists.
Percutaneous dilational tracheostomy following anterior cervical spine fixation - a retrospective propensity-matched cohort study.

Purpose: In patients with traumatic, infectious, degenerative, and neoplastic surgical indications in the cervical spine, commonly the anterior approach is used. Often these patients require a tracheostomy necessary due to prolonged mechanical ventilation. The limited spinal mobility and proximity to the surgical site of anterior cervical spine fixation (ACSF) could pose an increased risk for complications of percutaneous dilational tracheostomy (PDT.
