Yun Jeong Huh, Jeong Tae Kim, Jae Young Choi
Clin Exp Pediatr. 2005;48(2):216-220.   Published online February 15, 2005
Pulmonary arteriovenous fistulas(PAVFs) is a rare disorder that occurs in two to three children per 100,000 population. It is presented as absence of intervening capillary beds between the pulmonary artery and vein with resultant persistent right to left shunt. Other causes include trauma, liver cirrhosis, malignancy and schistosomiasis. It is mostly asymptomatic, but it may present with respiratory difficulty, cyanosis,...

Jung Hun Yew, Young Deuk Kim, Byung Seok Shin, Hong Ryang Gil
Clin Exp Pediatr. 2005;48(2):212-215.   Published online February 15, 2005
Renal artery stenosis is a major cause of renovascular hypertension and the most common cause of treatable secondary hypertension. There are several methods to treat renal artery stenosis, including surgery, percutaneous transluminal renal angioplasty(PTRA), and renal artery stenting(RAS). But, renal artery embolization can be tried in atherosclerotic stenosis, multiple stenosis, microaneurysm, and stenosis difficult to try PTRA or RAS. We...

Clin Exp Pediatr. 2004;47(11):1220-1224.   Published online November 15, 2004
Fetal alcohol syndrome can be suspected in infants born to mothers with a prenatal history of alcohol abuse if the child exhibits characteristic facial features, together with intrauterine growth retardation, multiple neurological abnormalities, and multiorgan defects. If only a few of the above criteria are satisfied, the term fetal alcohol effects is used. We experienced a neonate who presented with...

Jae Ju Cho, Woo Sung Park, I-Seok Kang, Tae-Gook Jun, Mi-Jin Jung
Clin Exp Pediatr. 2004;47(10):1114-1118.   Published online October 15, 2004
Congenital pulmonary vein stenosis(CPVS) with anatomically normal connection, a rare anomaly, usually leads to progressive pulmonary hypertension, cardiac failure in infancy, and death if untreated. Most are combined with other anomalies, particularly left to right shunt lesions. Very often, the detection of CPVS is overlooked on the initial cardiac echocardiogram, because it may be mild in its severity initially, but...

Pathophysiology of Persistent Pulmonary Hypertension of the Newborn
Yong Hoon Jun
Clin Exp Pediatr. 2004;47(7):707-715.   Published online July 15, 2004
Persistent pulmonary hypertension of the newborn(PPHN) is a disorder characterized by persistence of the pattern of fetal circulation after birth due to a sustained elevation of pulmonary vascular resistance. The two primary events in the pathophysiology of neonatal pulmonary hypertension are hypoxic pulmonary vasoconstriction(HPV) and hypoxic pulmonary vascular remodeling(HPR). Chronic hypoxemia may cause increased muscularity of the pulmonary arteries and...

Henoch-Shonlein purpura(HSP) is a systemic small-vessel vasculitis that primarily affects the skin, gastrointestinal tract, joints, and kidneys. The nervous system may be involved, less commonly than other organs. When the central nervous system(CNS) was involved, headache, changes in mental status, seizures, and focal neurologic deficits have been reported. Hypertension, uremic encephalopathy, metabolic abnomalities, electrolyte abnormalities, or cerebral vasculitis were suggested...

Mira Lee, Kil Soon Choi, Nam Su Kim, Myung Kul Yum, Yong Joo Kim, In Jun Sul
Clin Exp Pediatr. 2003;46(6):610-614.   Published online June 15, 2003
Pulmonary hypertension may be associated with variable conditions such as the hyperkinetic state or pulmonary vascular obstruction. In these, stenosis of the individual pulmonary veins without any cardiac or vascular malformation is very rare. We experienced stenosis of individual pulmonary veins in a 10 months old boy who was admitted with recurrent dyspnea and cyanosis and then underwent angiogram and...

Hemodynamic Effect of Nitric Oxide Inhalation in the Acute Hypoxic Pulmonary Hypertension Induced Newborn Piglet
Yun Cil Chang, Won Soon Park, Jung-Hwan Choi, Chong Ku Yun
Clin Exp Pediatr. 1997;40(10):1394-1409.   Published online October 15, 1997
Purposes : Nitric oxide(NO) is classified as toxic gas in native states, but in most biologic systems NO acts as a messenger molecule. NO is known as endothelium derived relaxing factor that modulates tone of vascular smooth muscle. Inhaled NO has been reported to act as a selective pulmonary vasodilator and we expect that NO inhalation can be used as a successful treatment modality...
