ABSTRACT
Considering the prioritization of life-threatening injuries in trauma care, secondary dysfunctions such as ventilator-induced diaphragmatic dysfunction (VIDD) are often overlooked. VIDD is an entity induced by muscle inactivity during invasive mechanical ventilation, associated with a profound loss of diaphragm muscle mass. In order to assess the incidence of VIDD in polytrauma patients, we performed an observational, retrospective, longitudinal study that included 24 polytraumatized patients. All included patients were mechanically ventilated for at least 48 h and underwent two chest CT scans during their ICU stay. Diaphragmatic thickness was measured by two independent radiologists on coronal and axial images at the level of celiac plexus. The thickness of the diaphragm was significantly decreased on both the left and right sides (left side: -0.82 mm axial p = 0.034; -0.79 mm coronal p = 0.05; right side: -0.94 mm axial p = 0.016; -0.91 coronal p = 0.013). In addition, we obtained a positive correlation between the number of days of mechanical ventilation and the difference between the two measurements of the diaphragm thickness on both sides (r =0.5; p = 0.02). There was no statistically significant correlation between the body mass indexes on admission, the use of vitamin C or N-acetyl cysteine, and the differences in diaphragmatic thickness.
ABSTRACT
The incidence of isolated iliac artery aneurysms is approximately 2% and common iliac artery pseudoaneurysms are even rarer. A pseudoaneurysm is a localized hemorrhage as opposed to an actual aneurysm, which affects the entire vascular wall. They are typically asymptomatic and only detectable accidentally while looking for other causes. If large and symptomatic, they typically exhibit pressure symptoms as a result of the compression of the structures around them. Common symptoms include generalized stomach pain, urological problems, gastrointestinal bleeding, and neurological symptoms such as leg paralysis or sciatica-like back pain. Rarely, they may exhibit hemodynamic instability together with an aneurysm rupture, which has a high fatality rate. Due to the unique presentation, the diagnosis is typically rarely made and there is little experience with treating it. We report two cases of common iliac artery pseudoaneurysm found in two patients who had no notable medical history and who we chose to repair through the endovascular technique in the first case, an approach that has gained more ground for vascular repair worldwide, making it the current go-to method, and for the second case we chose a more traditional approach, through open surgery.
ABSTRACT
Introduction: The treatment of blunt splenic injuries showed major evolutionary changes, from fundamental/ basic splenectomy to nonoperative and endovascular treatment, "catheter surgery". Currently, in Trauma Centers, splenic angioembolization is considered the first-line intervention in trauma. This article presents the Bucharest Emergency Clinical Hospital experience in the use of splenic angioembolization, a therapeutic solution in accordance with contemporary practice and literature. Methods: This retrospective study includes patients with splenic trauma by blunt mechanism, in which diagnostic / therapeutic angiography was performed, hospitalized in the Clinical Emergency Hospital Bucharest between January 2006 and December 2019. The main endpoints of the study were: post-traumatic mortality, the need for surgery (laparoscopic/classic) to resolve splenic bleeding, the number of days of hospitalization, the need for hospitalization for more than 1 day in the intensive care unit, the day when the platelet count began to increase, the evolution of laboratory parameters (hospitalization, preangiography, postangiography/embolization, discharge). A secondary endpoint of the study was the frequency of complications that did not require surgery. Results: During the mentioned period in 64 patients treated nonoperatively, diagnostic angiography was performed (27 cases, group B) or therapeutic angiography (37 cases, group A). 26.56% of cases were 55 years old (55-81 years old), the predominance of males being obvious (62.5%). The mean value of the ISS was 21.7 +- 10.4, and 71.87% of cases presented ISS 16. The mean value of the ISS was 21.7 +- 10.4, and 71.87% of cases presented ISS 16. The degree of splenic injury (American Association for the Surgery of Trauma-Organ Injury Scale) presented the mean value 2.95. The degree of splenic lesion was statistically significantly more severe in group A (p 0.001) and preangiography hemoglobin values were significantly lower compared to hospitalization values (p 0.001) indicating the persistence of hemorrhage. Procedural failures occurred in 4.68% of cases, with zero mortality. Conclusions: Splenic interventional radiology is a safe, effective and rational procedure. The development of therapeutic protocols is necessary to allow maximum use of this procedure.

OBJECTIVE: The primary aim of this article was to establish the actual prevalence of transposition and duplication of the inferior vena cava and to increase awareness about them. METHODS: A meta-analysis of prevalence was conducted of cases obtained from PubMed, Web of Science, and Scopus databases. RESULTS: A total of 48 studies contained data that allowed us to estimate the prevalence of these variants (39 for duplication and 32 for transposition). The overall prevalence of duplication was 0.7%, with a 95% confidence interval between 0.5% and 0.9%; for transposition, the prevalence was 0.3%, with a 95% confidence interval between 0.2% and 0.5%. The publication bias was minimal. Duplication prevalence was significantly higher in anatomy studies compared with imaging and surgery studies; for transposition, there were no statistically significant differences by detection technique. CONCLUSIONS: The overall prevalence of duplication of the inferior vena cava is 0.7%; for transposition, it is 0.3%. Even if they are obviously rare conditions, their presence must be suspected by practitioners as they can have important clinical consequences, may require changes in the surgery protocol, or can be associated with other congenital abnormalities.

INTRODUCTION: Postmortem CT angiography is the method of choice for the postmortem imaging investigations of the cardiovascular (CV) system. However, autopsy still remains the gold standard for CV measurement. Nevertheless, there are not any studies on CV measurements on the multi-phase postmortem angiography (MPMCTA) which includes comparisons with autopsy. Therefore, the aim of this study is to compare CV measurements between the native CT scan and the three phases of the MPMCTA to find out which of these modalities correlate the best with autopsy measurements. METHODS: For this study, we selected retrospectively 50 postmortem cases that underwent both MPMCTA and autopsy. A comparison was carried out between the CV measurements obtained with imaging (aorta; heart cavities and cardiac wall thicknesses; maximum cardiac diameter and cardiothoracic ratio) and at the autopsy (aorta; cardiac valves, ventricular thicknesses, and weight). RESULTS: Our results show that the dynamic phase displays an advantage for the measurement of the aortas. However, the MPMCTA is not accurate to measure the cardiac wall thicknesses. The measurements of the heart cavities show no correlation with the heart valves. The cardiothoracic ratio measured by the MPMCTA shows no correlation with the heart weight. Nevertheless, the maximum cardiac diameter exhibits a correlation with the latter on the venous and dynamic phase. CONCLUSIONS: These results show that only few CV parameters measured with imaging correlate with measurement obtained at the autopsy. These results indicate that in order to better estimate values obtained at the autopsy, we need to define new reference values for the CV measurement on MPMCTA.
