Patent Ductus Arteriosus Differential Diagnosis A great number of conditions show signs and symptoms similar to that of a PDA. Differential Cyanosis; Cyanosis seen only in the lower part of the body; Causes: interrupted aortic arch or critical coarctation of the aorta in the presence of a patent ductus arteriosus (PDA) due to right to left shunt to the lower part of the body (Figure A) TOF 2. Differential cyanosis classically occurs in PDA with reversal of shunt when raised PA pressures /PVR is able to supersede the systemic Aortic pressure and drive the blood from LPA to descending Aorta bringing down the lower limb saturation. https://www.ahajournals.org/doi/10.1161/circulationaha.105.592063 Differential cyanosis and clubbing is typical of PDA with Eisenmenger's syndrome. Differential Cyanosis. Pulmonary valve atresia with the intact ventricular septum 1. Ebstein’s anomaly 3. Differential cyanosis, meaning cyanosis and clubbing of the lower extremities with normal upper extremity nailbeds, is diagnostic of PDA with pulmonary hypertension. A 12-year-old Chinese girl with a 10-year history of heart murmur and differential cyanosis was referred to our institution for minimally invasive transthoracic PDA closure. Familial clustering of congenital deafness, patent ductus arteriosus, Eisenmenger complex, and differential cyanosis: A case report All causes of central cyanosis can also cause peripheral cyanosis. Cardiopulmonary causes and hemoglobin abnormalities are the common causes of central cyanosis. Differential cyanosis can be seen in patent ductus arteriosus with pulmonary hypertension. Differential Cyanosis • Asymmetrical cyanosis between upper and lower extremities, usually lower limbs more than the upper limbs. Q. Transposition of great arteries 1. It is the term used for conditions where the Cyanosis is present in certain parts and absent in others. T.M. Reverse Differential Cyanosis: In some cases, neonates can present with reverse differential cyanosis (defined as higher saturation in lower extremities compared to upper extremities) from right to left shunting at the PDA in cases of D-TGA with coarctation, D-TGA with pulmonary hypertension or D-TGA with interrupted aortic arch (IAA). Furthermore, differential cyanosis (ie. Pathophysiology. The clinical finding of differential cyanosis as outlined above is pathognomonic for a large untreated PDA associated with Eisenmenger syndrome (shunt reversal into a right-to-left shunt due to progressive pulmonary vascular disease). On transfer to the cardiovascular intensive care unit, the patient was responsive and noted to have differential cyanosis, with decreased oxygen levels in … Critical coar… Differential cyanosis is caused by the location of the PDA, which shunts right to left from the pulmonary artery into the descending aorta. Interrupted aortic arch 3. Differential cyanosis (PDA) Ammonia level; Urinary amino acid and organic acid screen; CMV, HSV PCR; Cranial ultrasound; c) Approach to management, which is very generic: Assess the need for endotracheal intubation. Doceri is free in the iTunes app store. It may suggest a problem with the lungs or heart. On echocardiography there was evidence of severe pulmonary hypertension and a large patent ductus arteriosus (PDA) with … As clinically suspected, a large patent ductus arteriosus (PDA) was found (marked with asterisk in Panel D ). The clinical finding of differential cyanosis as outlined above is pathognomonic for a large untreated PDA associated with Eisenmenger syndrome (shunt reversal into a right-to-left shunt due to progressive pulmonary vascular disease). TOF with pulmonary atresia 4. DOI: 10.1056/NEJMicm1008597. Differential cyanosis is a characteristic examination finding in animals with reverse PDA. 14, 15 Desaturated blood from the ductus enters the aorta distal to the left subclavian artery, sparing the brachiocephalic circulation. Since PDA is usually identified in infants, it is less common in adults, but it can have serious consequences, and is usually corrected surgically upon diagnosis. cyanotic in the lower extremities) is a manifestation of an extreme pre- to post-ductal PaO 2 gradient, which can occur in PPHN with interrupted aortic arch, and coarctation of the aorta. - At this stage, senior assistance from somebody expert in paediatric critical care is required, as the intubation may be difficult. Adults with undiagnosed PDA may present with signs and symptoms of heart failure, atrial arrhythmia (due to progressive left atrial enlargement) or even differential cyanosis limited to the lower extremities, indicating shunting of deoxygenated blood from the pulmonary to systemic circulation. A … The typical continuous murmur is absent. Differential cyanosis refers to the situation where upper limb saturation is higher than lower limb and it is well documented to be caused by persistent pulmonary hypertension in newborn (PPHN) or patients with patent ductus arteriosus and Eisenmenger syndrome in adults [2-4]; Table 1. Lin TW(1), Tseng CW, Huang CY, Wang KY, Liang KW. Hypoplastic left heart syndrome 2. 1. Robert Edward Gross, MD performed the first successful ligation of a patent ductus arteriosus on a seven-year-old girl at Children's Hospital Boston in 1938. Truncus arteriosus 2. Total anomalous pulmonary venous return without obstruction 3. The conditions associated include Co-Arctation of the Aorta (CoA), Patent Ductus Arteriosus, Persistent fetal circu-lation, Persistent pulmonary hypertension (PPHTN). In addition, perfusion of the kidneys with deoxygenated blood causes excessive release of erythropoietin and subsequent polycythemia. Differential cyanosis is the bluish coloration of the lower but not the upper extremity and the head. At that time, there was differential cyanosis with clubbing and lower oxygen saturations in the toes (82%) compared with her fingers (95%). This video screencast was created with Doceri on an iPad. 1) Differential cyanosis: Often cyanosis is associated with clubbing Cyanosis only in lower limbs: PDA with reversal of shunt (Eisenmenger PDA or reverse PDA) Mechanism: Desaturated blood from the ductus enters the aorta distal to the left subclavian artery, sparing the … It is the term used for conditions where the cyanosis is present in certain parts and absent in others. CYANOSIS ‐ TYPES – Central – cyanotic CHD – Peripheral – hypothermia, CCF – Mixed Cyanosis – CHD in Shock – Differential cyanosis – PDA with reversal – Reverse differential cyanosis – TGA with PDA with reversal – Intermittent Cyanosis – Ebsteins anomaly – Circumoral cyanosis • This finding suggested of Rt.-to-Lt. Shunt from PDA Differential Cyanosis Cause1 -PPHN with PDA -PDA with severe pulmonary hypertension (Eisenmenger Syndrome) -Interrupted aortic arch -Severe coarchtation of aorta with VSD and PDA after prolonged rupture of membranes with varying degrees of pulmonary hypoplasia are at higher risk of developing pulmonary hypertension. In considering differential cyanosis, the upper body is cyanotic reflecting the presence of a cardiac condition leading to hypoxemia of the upper extremities. A PDA is graded as large when signs of pulmonary hypertension have developed. Perfusion of the kidneys with hypoxemic blood leads to secondary polycythemia and hyperviscosity, with the PCV gradually increasing to 65% or greater. Reversed differential cyanosis may occur with complete transposition of the great vessels associ-ated with pulmonary hypertension and a patent ductus arteriosus. This DC is seen when right-to-left shunting occurs from the pulmonary artery to the descending aorta through a patent ductus arteriosus (PDA). Patent ductus arteriosus (PDA) is a common congenital heart defect in dogs, and it occurs less commonly in cats. Persistence of a normal fetal structure (ductus arteriosus) after birth allows for shunting of blood from the descending aorta to the pulmonary artery, leading to volume overload and subsequently left heart failure. Familial clustering of congenital deafness, patent ductus arteriosus, Eisenmenger complex, and differential cyanosis: A case report. Anoop, M.D., and K.C. The newborn can experience two types of differential cyanosis (DC). Patients with a large ductus develop progressive pulmonary vascular disease, and pressure overload of the right ventricle occurs. Only of lower limbs: due to patent ductus arteriosus (PDA) with reversal of shunt. Only of lower limbs- Patent ductus arteriosus (PDA) with reversal of shunt. George, M.D. Patent ductus arteriosus (PDA) is a defect in which there is an open connection between the aorta and pulmonary artery. Differential cyanosis and clubbing is typical of PDA with Eisenmenger's syndrome. Learn more at http://www.doceri.com List of authors. Only of upper limbs- PDA with reversal of shunt in transposition of great vessels. The second type of DC, reversed differential cyanosis (RDC), occurs when oxygen saturation is lower in the right hand than in the foot. PDA associated PAH. It is most easily seen where the skin is thin, such as the lips, mouth, earlobes and fingernails. The common type of DC occurs when oxygen saturation in the right hand is greater than in the foot. [citation needed] It results when the deoxyhemoglobin exceeds 5.0 g/dL. The differential diagnoses for PDA includes ensuring the absence of conditions such as: Physical examination revealed differential cyanosis with oxygen saturation in the upper and lower extremity of 95 and 86%, respectively. This is seen in patients with a patent ductus arteriosus. Familial clustering of Eisenmenger PDA and congenital deafness is rare. Grade 4 patients are mostly adults with Eisenmenger syndrome. Cyanosis indicates there may be decreased oxygen attached to red blood cells in the bloodstream. Total anomalous pulmonary venous return (TAPVR) Differential cyanosis/O2 differential Refers to the appearance of cyanosis in both lower extremities with pink right upper extremity Pre- and postductal difference of more than 20 torr in PaO2 or at least 5% difference in oxygen saturation Of course, this can be undone by the presence of any other intra-cardiac shunts or aberrant left subclavian that arising from the desaturated … Cyanosis in the left arm and legs is ob- served occasionally in persistent ductus ar- teriosus and severe pulmonary arterial hyper- tension,is When an aberrant subclavian artery is present, a paradoxical type of differential cyanosis, i.e., cyanosis of the right arm and legs … Differential cyanosis, in which the oxygen saturation of the feet is lower than that of the right arm, is typically seen. Differential Clubbing and Cyanosis. Cyanosis refers to a bluish-purple hue to the skin. The common type of DC is observed in normal transitional pulmonary hypertension … In this dog, the absence of differential cyanosis, a typical clinical finding in patients with r-PDA, was misleading. Differential cyanosis refers to the situation where upper limb saturation is higher than lower limb and it is well documented to be caused by persistent pulmonary hypertension in newborn (PPHN) [1] or patients with patent ductus arteriosus and Eisenmenger syndrome in adults [2-4]; Table 1. The clinical finding of differential cyanosis as outlined above is pathognomonic for a large untreated PDA associated with Eisenmenger syndrome (shunt reversal into a right-to-left shunt due to progressive pulmonary vascular disease). Only of upper limbs: due to PDA with reversal of shunt in transposition of great vessels. This phenomenon is observed in transposition of the great arteries (TGA) with patent ductus arteriosis (PDA) and elevated pulmonary vascular resistance or in TGA with PDA and preductal aortic interruption or coarctation. Shunt reversal causes deoxygenated blood from the RV to be shunted to … N Engl J Med 2011; 364:666. Further studies are warranted to define possible genetic links. Cyanosis is due to inadequate oxygenation of blood. Adult. What is Differential Cyanosis? Hence, it is necessary to diagnose PDA accurately in order to ensure that appropriate medical care is administered to a baby. Oxygenated blood from the left ventricle passes into the pulmonary artery and throughthepatentductusarteriosustothedescend-ing aorta, while systemic venous blood flows from Differential cyanosis can be seen in patent ductus arteriosus with pulmonary hypertension. February 17, 2011.
