Introduction: Vascular compromise causes hand pain, and physical examination requires to differentiate vascular causes from isolated ulnar nerve compression. Diagnostic studies visualize vascular abnormalities such as CT scans, MRA scans, and AV fistulograms. Ulnar artery aneurysms are quite rare discoveries, related to repetitive trauma, vasculitis, anatomic abnormalities, or infections. It is...

Obstructive hypertrophic cardiomyopathy (obstructive HCM) is a hereditary disease characterized by septal hypertrophy and dynamic left ventricular outflow tract (LVOT) obstruction. Other than hypertrophy, mitral valve abnormalities are also quite common in patients with obstructive HCM, which may contribute to systolic anterior motion (SAM) of the LVOT Surgical myectomy standard treatment achie...

SUMMARY Serial histologic sections of the atrioventricular (A-V) conduction system were studied in four hearts with persistent common A-V canal, and the anatomic findings were related to the abnormal ECG pattems. Two hearts were examples of the partial form and two of the complete form of A-V canal. The major anatomic abnormalities were: (1) postero-inferior displacement of the A-V node; (2) re...

BACKGROUND In patients with recurrent persistent atrial fibrillation (AF), vulnerability to AF persists indefinitely despite presumed completion of reverse electrical remodeling within days of return to normal sinus rhythm. Atrial electrical and anatomic remodeling and reverse remodeling were studied in a canine model of chronic AF. METHODS AND RESULTS Chronic AF was induced in 8 dogs by crea...

PurposeTo characterize growth abnormalities after surgical treatment of tibial spine fractures and to investigate risk factors for these abnormalities.MethodsA retrospective analysis children who underwent between January 2000 2019 was performed, drawing from a multicenter cohort among 10 tertiary care children’s hospitals. The entire surgically treated analyzed incidence disturbance. stratifie...

We report on a case of juvenile granulosa cell tumor of the testicle in a neonate, a rare testicular tumor in children. No genital ambiguity, anatomic abnormalities, nor sex chromosome aneuploidy was noted in this patient. In our case, despite positive staining for alpha-fetoprotein which is most consistent with yolk sac tumors, all clinical, gross anatomic, histologic, and other immunohistolog...

Patellar instability is a complex pathoanatomical phenomenon that requires an intricate understanding in order to properly treat patients. Often, the etiology of this entity is multifactorial, combining a series of physiologic and anatomic variables. A thorough history and physical as well as correct radiographic examinations are critical in both establishing the diagnosis and instituting the c...

The anatomic abnormalities observed by cineangiographic axial techniques of 12 patients with tetralogy of Fallot were correlated with anatomic details noted at necropsy. Right ventricular angiograms made in the right anterior oblique view best demonstrated the severity and type of infundibular obstruction and also permitted differentiation of the perimembranous, infundibular muscular and subart...

BackgroundRetroaortic innominate vein (RAIV) is an extremely rare anomaly of systemic venous return. The prevalence RAIV has been estimated to be 0.02% in individuals without congenital heart disease and 0.5% those with disease. Previous studies have demonstrated association between both conotruncal abnormalities right aortic arch. Our center specializes surgical procedures for patients pulmona...
