An explanation of the progression of stenotic lesions was sought in animal experiments. After surgical decrease of the lumen of arteries, progressive ingrowth of fibrous connective tissue led to the development of stenosis with changes in the artery that resembled those of coaretation. These changes are explained by the action of local blood pressures. Phenomena such as progressive stenosis, va...

Prenatal sonographic features of the rare anomaly of complete duplication of the urinary bladder and urethra are described in this case report. A coronal scan of the fetal pelvis at 29 weeks of gestation revealed two pyriform cystic structures. The umbilical arteries coursed around both of them. They emptied independently of each other. Postnatally the newborn had two vulvae, two anal openings,...

Fatal haemopericardium occurred in a 14-year-old boy after rupture of a pulmonary artery aneurysm. Persistent ductus arteriosus with severe pulmonary hypertension was confirmed by cardiac catheterisation when he was 4 weeks old. Attempted closure of the ductus at 4 years had not been possible because of apparent high pulmonary resistance. Exercise tolerance had been good enough to permit compet...

BACKGROUND Double gallbladder (GB) is a rare congenital anomaly of the biliary system characterized by the presence of an accessory GB. CLINICAL FINDINGS A 38-year-old female presented with a history of right upper quadrant (RUQ) pain. Computed tomography (CT) showed a lobulated cystic mass involving the center portion of liver. Magnetic resonance imaging (MRI) additionally revealed a tubular...

BACKGROUND Acute pulmonary exacerbations are associated with progressive lung function decline and increased mortality in cystic fibrosis. The role of pulmonary vascular disease in pulmonary exacerbations is unknown. We aimed to assess the association between pulmonary artery enlargement (defined as pulmonary artery diameter to ascending aorta diameter [PA:A] ratio >1), a marker of pulmonary va...

The levo-transposed aorta has previously been considered diagnostic of corrected transposition of the great arteries and hence ventricular inversion in situs solitus. Increasing experience with conotruncal abnormalities has shown that an abnormally leftward aorta may be found in patients with normally related ventricles (D-ventricular loop) and hemodynamically complete transposition of the grea...

double-j (dj) stents are the main tools used in urological practice for prevention and treatment of obstruction. stenting is also mandatory after complicated ureteroscopy or tul (transureteral lithotripsy). known complications are upper migration of dj stents into the kidney and lower migration to the bladder. in a man with an impacted right lower ureteral stone, a dj stent was placed because t...

Double right coronary artery (RCA) is an extremely rare coronary artery anomaly. We aimed to report an atherosclerotic double RCA which appeared after primary percutaneous intervention performed to treat acute inferior myocardial infarction. This is the first case in the literature, which the coronary arteries that can be accepted as double RCA have been hidden by total atherosclerotic occlusio...

Angiographic evidence of thrombosis in more than one coronary artery at the same time is uncommon patients with acute myocardial infarction, and this hard to identify routine electrocardiography. Patients may manifest high-degree atrioventricular block, cardiogenic shock, or sudden cardiac arrest, all which are potentially fatal outcomes. This case study focuses on a patient who experienced blo...
