traumatic coronary artery-cameral fistulas (tcaf) are rare and may present secondary to penetrating injuries (80%) or iatrogenic traumas. early operative intervention remains the recommended treatment modality for accidental traumatic coronary artery fistulas. we report the case of a 17-year-old man who presented with left anterior descending coronary artery-right ventricle fistula following pe...

coronary artery anomalies are rare, with their incidence varying from 1 to 5%. angiography is a commonly used modality for the assessment of coronary artery anomalies. based on previous reports, a majority of coronary artery anomalies are of origin or distribution, with separate ostia of the left anterior descending artery and left circumflex artery. coronary artery anomalies may cause myocardi...

Nowadays, one of the main problems encountered in minimally invasive surgery and telesurgery is the detection of arteries in tissue. In this study, for the first time, tactile detection of an artery in tissue and distinguishing it from the tumor has been modeled by finite element method. In this modeling, three 2D models of tissue have been created: tissue, tissue including a tumor, and tissue ...

Recognizing the arterial variations of human upper extremities is of potential clinical practice because this area is involved in arterial handling and invasive medical procedure. During dissection of the left upper limb of a 35-year-old male embalmed cadaver, we saw brachial artery bifurcation in the middle third of proximal portion of the arm. Its medial branch descended along the medial side...

Introduction: Knowledge of the presence of the alveolar antral artery in the lateral maxillary sinus wall is essential for surgeons who operate in this region. The purpose of this study was to investigate the correlation between alveolar antral artery diameter and lateral maxillary bony wall thickness in dentate patients.   Materials and Methods: Thirty five Cone-Beam Computed Tomography (CBCT)...

our case was a 48-year-old man with cervical pain radiatingto the upper limbs. imaging showed an intradural tumor with extradural component encasing the vertebral artery.thetumor diagnosed asa neurinomaand had been removed surgically.the post operationmagnetic resonance imagingshowed that the tumor was completely removed andthe vertebral arterywas intact at theentire length.the goal of surgery ...

background: according to the angiographic findings, 3%-8% of atherosclerotic coronary artery patients suffer from coronary artery ectasia (cae). we conducted this study to estimate the prevalence of cae among patients who underwent angiography and compared this group with those patients without cae and atherosclerosis in terms of common coronary heart disease (chd) risk factors. methods : this ...

the macroscopic study of 31 adult cadavers proved a variation to matula and lang's study. in 2 cases (6.4%) a prevertebral segment ran up to cy in one of which (3.2%) the middle cervical ganglion was pierced. this, we believe, is significant not only in diagnosis but also in surgical and endovascular treatment.
