Background: The aberrant origin of the right subclavian artery (ARSA), also known as the lusoria artery, is a congenital malformation with an incidence of 0.5–4.4%. Most cases are incidental due to minimal clinical manifestations. Computer tomography (CT) is important in diagnosing and evaluating these patients. Materials and Methods: We conduct a computerized search in two databases, PubMed and EMBASE, for articles published between 1 January 2022 and 31 December 2023, PROSPERO code: CRD42024511791. Eligible for inclusion were case reports and case series that presented the aberrant origin of the right subclavian artery. The main outcome was the highlighting of the morphological types of ARSA. In this context, we proposed a new classification system of this anomaly. The secondary outcome was the evaluation of the demographic distribution of the lusoria artery. Results: Our search identified 47 articles describing 51 patients with ARSA. The typical course for ARSA is retroesophageal, being registered in 49 out of 51 patients. This malformation is frequently associated with Kommerell diverticulum (15 out of 51), troncus bicaroticus (7 out of 51), and aberrant origins of the right vertebral artery (7 out of 51). We observed a higher incidence of the condition among women (32 out of 51) compared to men (19 out of 51). From a demographic point of view, ARSA is more frequent in the “44 to 57 years” and “58 to 71 years” age ranges. Conclusions: ARSA is a congenital malformation resulting from a defect in the development of the aortic arches. The imaging studies such as computer tomography play a defined diagnostic role.

(1) Background: The aortic arch (AA) branching model is challenging, considering the multiple anatomical variations documented in existing research. The bovine aortic arch (BAA) is the most prevalent anatomical variation among these. This variant of AA branching has long been considered a nonsymptomatic malformation, having been discovered incidentally during imaging investigations for other causes. However, more recent studies have demonstrated that BAA shows a frequent association with coarctation of the aorta (CoA), thoracic aortic disease (TAD), and stroke. At the same time, given the current context of increasing activity in the fields of interventional and surgical procedures in the aorta and its branches, it is very important to know the medical–surgical implications of this anatomical variant. (2) Methods: We conducted a comprehensive review using PubMed and Embase, focusing specifically on randomized trials and cohort analyses that examined the medical–surgical implications of BAA. We assessed information related to studied groups, medical procedures, and study outcomes. Initially, we identified 8454 studies, and after rigorous evaluation, we narrowed down our review to 25 articles. (3) Discussions: The intervention consisted of assessing the risks associated with BAA through different imaging investigation methods such as computer tomographic angiography (CTA), magnetic resonance imaging (MRI), or ultrasonography (US). The following results were evaluated: the prevalence of the BAA, the importance of imaging investigations in establishing the diagnosis and the therapeutic management and monitoring the evolution of patients with the BAA, the association of the BAA with CoA, TAD, and stroke, and the potential risks of interventional treatment in patients with the BAA. (4) Conclusions: The prevalence of the BAA differs both between different ethnic groups and between genders. Advanced imaging methods such as CTA and 4D flow MRI allow detailed descriptions of supra-aortic vascular anatomy and information about blood flow velocities, direction, and turbulence in the AA. US remains an easy and valuable imaging investigation, with the potential to detect and correctly diagnose the BAA and its hemodynamic implications. Anatomical variations in the AA are associated with increased rates of TAD, CoA, and stroke, necessitating early diagnosis and increased supervision of patients with such incidentally observed abnormalities. In addition, there is a need to further develop and refine the surgical techniques used and personalize them to the individual characteristics of patients with the BAA.

Introduction: The triangular recess (TR), also called triangular fossa or vulva cerebri, represents the anterior extension of the diencephalic ventricle, located between the anterior columns of the fornix and the anterior white commissure. Over time, this structure of the third cerebral ventricle generated many disputes. While some anatomists support its presence, others have opposite opinions, considering that it only becomes visible under certain conditions. The aim of the study is to demonstrate the tangible structure of the triangular recess. Secondly, the quantitative analysis allowed us to establish an anatomical morphometric standard, as well as the deviations from the standard.Materials and methods: Our study is both a quantitative and a qualitative evaluation of the triangular fossa. We dissected 100 non-neurological adult brains, which were fixed in 10% formaldehyde solution for 10 weeks. The samples are part of the collection of the Institute of Anatomy, “Grigore T. Popa” University of Medicine and Pharmacy, Iasi. We highlighted the triangular fossa by performing dissections in two stages at the level of the roof of the III ventricle.Results: The qualitative analysis is a re-evaluation of the classical data concerning the anatomy of the fossa triangularis. We proposed an original 3D model of the triangular recess in which we described a superficial part called vestibule and a deep part called pars profunda. We measured the sides of the communication between the two proposed segments, as well as the communication with the III ventricle. By applying the Heron’s formula, we calculated the area of the two communications. Statistical evaluations have shown that these communications are higher than they are wide. In addition, there is a statistical difference between the surfaces of the two communications: 34.07 mm² ± 7.01 vs. 271.43 mm² ± 46.36 (p = 0.001).Conclusion: The outcome of our study is both qualitative and quantitative. Firstly, we demonstrated the existence of the triangular fossa and we conceived a spatial division of this structure. Secondly, the measurements carried out establish an anatomo-morphometric norm of the triangular recess, which is useful in assessing the degree of hydrocephalus during the third endoscopic ventriculoscopy.

Introduction. The pneumatized cavities of the skull are characterized by the presence of numerous anatomical variants. Among these, the aberrant pneumatization of the middle turbinate is noteworthy, both in terms of prevalence and in terms of clinical resounding. The identification of this anomaly can be achieved clinically through anterior or posterior rhinoscopy, but the diagnostic gold standard is represented by spiral computer tomography (CT) and cone-beam computed tomography (CBCT) scans. Our study aims to determine the prevalence of concha bullosa (CB) in the Romanian population and to observe the distribution of the anomaly according to sex and age groups. Secondarily, we propose a new clinical classification based on the morphological appearance of concha bullosa. The selected cases will be distributed according to this new classification. Thirdly, we will study the association of concha bullosa with rhinosinusitis. Materials and methods. Our retrospective randomized study included 105 CT scans of non-traumatic patients (mean 60.34 ± 20.48 years) who underwent cranio-cerebral examinations between 01.07.2023 - 31.12.2023 in the Iasi Clinical Rehabilitation Hospital. Results. Concha bullosa was identified in 57 patients out of 106 (53.77%). Among them, 30 (28.3%) had the bilateral form and 27 (25.47%) the unilateral form. The applied statistical tests demonstrated a uniform distribution by age and gender groups. Within the classification proposed by us, we have identified all nine subtypes. Between subtypes I (A, B, C) and subtypes II (A, B, C), we recorded statistical significance (p = 0.00092), with the predominance of the lamellar type over the bulbous type. Conclusions. Concha bullosa has a high prevalence in the studied cohort. It does not show variations related to age or sex, which supports the malformative origin. The classification proposed by us ensures a better picture of the local mass effect determined by CB.

Background and Objectives: Haller Cells (HCs) represent the abnormal migration of ethmoid cells that are located below the ethmoid bulla at the level of the upper wall of the maxillary sinus. Through their placement, the cells can exert a mass effect on the infundibulum of the maxillary sinus. The aim of our study is to investigate the prevalence of Haller cells in the Romanian population and to evaluate the relationship between this anatomical variation and chronic rhinosinusitis. Secondly, we want to morphometrically evaluate the impact of Haller cells’ presence in the drainage paths of the maxillary sinuses. Materials and Methods: We conducted a randomised retrospective study that included 255 consecutive multi-detector computed tomography (MDCT) scans of the head. To carry out a comparative evaluation of the association of Haller cells with chronic rhinosinusitis, we divided the patients into two subgroups, a seasonal-based sample, between November 2022 and January 2023, and June 2023 and August 2023, respectively. We report the mean ± standard deviation for the continuous variables. To compare the results, we used the following statistical tests: a chi-squared test and a paired Student’s t-test (one-tail). Results: Our study identified a high prevalence of Haller cells, namely in 128 out of 255 patients (50.2%). There were no statistically significant associations between the presence of HCs and the age and the gender of the sample, respectively. The unilocular morphotype predominates in unilateral shapes and in bilateral shapes as well (p = 0.002). Our study identified the correlation between the Haller cells and the chronic rhinosinusitis in both research samples: “Winter group” and “Summer group” (p = 0.0002 and p = 0.0001, respectively). Conclusions: It was determined that for 40 out of 42 patients, the presence of HCs changes the morphometric pattern of the infundibular maxillary sinus.

Background: Articular damage is a marker of hereditary hemophilia, especially affecting the large joints of the upper and lower limbs. This retrospective study aimed to emphasize that hereditary coagulopathies, specifically hemophilia A and B, require a multidisciplinary approach due to their complex nature. The primary objectives of the paper are to determine the prevalence of hemophilic arthropathy among individuals with hemophilia in the northeastern region of Romania, identify the most frequently affected joints, and assess whether there is a correlation between the development of hemophilic arthropathy, the type of hemophilia, and the treatment received. The secondary objectives of the work are to identify a series of particularities regarding the occurrence of the comorbidities depending on the type of hemophilia and the treatment and severity of arthropathies. Materials and Methods: We conducted a retrospective study that included 36 adults with hemophilia A and B. The status of the osteoarticular system was evaluated using the modified Hemophilia Joint Health Score (mHJHS). Twelve joints were evaluated using the following parameters: swelling, duration of swelling, muscle atrophy, joint pain, crepitus on motion, flexion loss, and extension loss. Results and Discussions: The most severe damage was found in the joints of the knees, ankles, elbows, and wrists. In the knees, severe damage was noted significantly more frequently in the right knee (50% vs. 33.3%; p = 0.001). In the ankles, a higher frequency of mild damage to the left ankle was noted (44.4% vs. 27.8%; p = 0.002). The severe form of hemophilia was correlated with severe joint damage (p < 0.05). Comorbidities like cardiovascular disease, obesity, viral infection (HCV infection), and gastrointestinal disease were found in the hemophilia population of our study. All patients with HCV infection had severe joint damage, while 38.5% of patients without HCV infection had mild joint damage, and 30.8% had no joint damage (p = 0.001). In all patients with HCV virus infection, the treatment was short-term substitution (intermittent prophylaxis), while in 53.8% of patients without HCV virus infection, the treatment consisted of continuous prophylaxis (p = 0.001). Conclusions: It is currently essential to determine methods for comprehensive hemophilia care that involves multidisciplinary medical services necessary for the diagnosis, treatment, and management of the condition and its complications and comorbidities.
