Pulmonary sling is a rare congenital condition in which the left pulmonary artery arises from the right pulmonary artery forming a sling around the trachea causing tracheal compression. Many cases are associated with cardiovascular and tracheo-bronchial anomalies. When combined with complete tracheal ring, it is called "ring-sling complex". The average onset of symptoms is 2 months and about ha...

PURPOSE The purpose of this study is to report a case of nontuberculous mycobacterial infection after frontalis sling surgery. METHOD A 65-year-old man presented with bilateral painful, erythematous lesions in the brow and upper eyelids. He had a history of frontalis sling surgery for myopathic ptosis 2 years back and all lesions were found localized to the tract of the silicone rod used in t...

Introduction In corrected transposition of the great arteries (CTGA), the presence of 2 atrioventricular nodes (twin AVNs), their Purkinje systems, and a specific conduction system (Mönckeberg sling) connecting them to each other has been demonstrated using histologic and electrophysiological techniques.. Twin AVNs can induce supraventricular tachycardia (SVT) as a preoperative, perioperative, ...

Pulmonary artery sling is frequently accompanied by tracheal anomalies other than local compression, including focal/segmental or extensive stenosis (ring-sling complex). Recent advances in computed tomography technology, such as multidetector computed tomography with 3-dimensional imaging (3-D) and virtual bronchoscopy (VB), offer important and accurate information of the entire tracheobronchi...

We were very interested to read the recent study by Welk and Herschorn, and the related commentary by Steele, regarding the role of autologous rectus fascial slings for complex recurrent female stress urinary incontinence (SUI).1,2 The authors report that, on mediumterm follow-up of 33 women with previous failed continence surgery, pubovaginal sling was associated with a significant reduction i...

Pulmonary sling is the anatomic variant defined by the aberrant origin of the left pulmonary artery from the right pulmonary artery. This patient presented with a mimic of pulmonary sling as a result of an extremely rare condition, arterial tortuosity syndrome (ATS). The patient was first diagnosed with pulmonary sling on prenatal echocardiogram performed by cardiology. Computed tomography angi...

Surgical exploration of a 7-week-old infant with a diagnosis of 'pulmonary artery sling' (left pulmonary artery arising from the right) revealed the true nature of the abnormality to be persistence of the ductus arteriosus which connected the right pulmonary artery to the aortic isthmus. This malformation has not been described previously. It has the same symptomatology as 'pulmonary artery sli...

An approach is presented to investigate the 1:2 internal resonance of sling and beam a suspension sling–beam system. The was taken as geometrically linear Euler beam, considered be nonlinear. dynamic equilibrium equation structures derived using modal superposition method, D’Alembert principle Hamilton principle. nonlinear equations free vibration forced oscillation were solved by multiple-scal...
