Cardiac arrest with retropharyngeal hematoma caused by minor facial injuries from a ground level fall.

Background: Traumatic retropharyngeal hematoma followed by airway obstruction is extremely rare. In this report, we show unique images from two cases of out-of-hospital cardiac arrest due to airway obstruction caused by massive retropharyngeal hematoma after a minor facial injury.

Case Presentation: Case 1: A 78-year-old man was transferred to our emergency department due to cardiac arrest.

Minimally invasive surgery technique for unstable pelvic ring fractures with severe vertical shear displacement: A retrospective study.

Background: Unstable pelvic fractures, especially vertical shear fractures, require surgery for correct reduction, rigid fixation, and improved postoperative outcomes. Herein, we assess the effectiveness of our minimally invasive procedure for the management of unstable pelvic fractures.

Hypothesis: We hypothesized that this procedure would be useful for the management of unstable pelvic fractures.

Retrospective high volume comparative study suggests that patients on aspirin could have immediate surgery for hip fractures without significant blood loss.

Purpose: This study aimed to investigate the effects of aspirin on peri-operative hidden blood loss during hip fracture surgery by adjusting for possible factors affecting blood loss using a propensity score matching method.

Methods: We retrospectively collected data from a cohort of isolated hip fracture patients (aged ≥ 65 years)who underwent surgery from January 2010 to December 2019. The study's primary outcome was blood loss from admission to the day after surgery in the aspirin and control groups.

Evaluating the need for and effect of percutaneous transluminal angioplasty on arteriovenous fistulas by using total recirculation rate per dialysis session ("clearance gap").

The functioning of an arteriovenous fistula (AVF) used for vascular access during hemodialysis has been assessed mainly by dilution methods. Although these techniques indicate the immediate recirculation rate, the results obtained may not correlate with Kt/V. In contrast, the clearance gap (CL-Gap) method provides the total recirculation rate per dialysis session and correlates well with Kt/V.
