Abernethy malformation: A comprehensive review
No full textAbernethy malformation is a rare condition in which portomesenteric blood bypasses the liver and drains into the systemic vein through a partial or complete shunt. It is categorised into two types on the basis of the shunt pattern between the portal vein and systemic vein. Abernethy malformation is associated with multiple congenital anomalies and acquired complications. A detailed understanding of anatomy and embryology is a prerequisite to interpret the imaging findings. Computed tomography and magnetic resonance angiography can delineate the shunt anatomy and evaluate the concomitant malformations. It is essential to differentiate Abernethy malformation from intrahepatic portosystemic shunts and acquired extrahepatic portosystemic shunts. Mild metabolic abnormalities are treated with dietary modifications and medical therapy. Definitive treatment is done in symptomatic patients. Generally, type I Abernethy patients undergo liver transplantation, and type II undergo shunt occlusion by surgery or transcatheter coiling

Evaporative Roof Cooling - A Simple Solution to Cut Cooling Costs
No full textSince the "Energy Crisis" Evaporative Roof
Cooling Systems have gained increased acceptance
as a cost effective method to reduce the high cost
of air conditioning. Documented case histories in
retrofit installations show direct energy savings
and paybacks from twelve to thirty months.
The main operating cost of an Evaporative
Roof Cooling System is water. One thousand
gallons of water, completely evaporated, will
produce over 700 tons of cooling capability.
Water usage seldom averages over 100 gallons per
1000 ft^2 of roof area per day or 10 oz. of
water per 100 ft^2 every six minutes.
Roof Cooling Systems, when planned in new
construction, return 1-1/2 times the investment
the first year in equipment savings and operating
costs. Roof sprays are a low cost cooling
solution for warehouses, distribution centers and
light manufacturing or assembly areas with light
internal loads. See text "Flywheel Cooling.

Abernethy malformation: A case report
No full textCongenital portosystemic shunts are rare congenital vascular malformations characterized by a partial or complete portal blood diversion into the systemic circulation. Congenital extrahepatic portosystemic shunts, known as Abernethy malformations, pose a diagnostic challenge due to their low incidence and clinical presentations.
A 15-year-old male with a history of chronic epigastric pain and nausea, high arterial blood pressure, recurrent nose bleeds, chest pain, dizziness, dyspnea, low exercise tolerance, hematochezia, and itching was diagnosed with Abernethy malformation type Ib. Imaging studies revealed a dilated portal vein conduit flowing into the inferior vena cava, bypassing the porta hepatis. Multiple liver nodules, heart chamber dilatation, myocardial hypertrophy, and pulmonary hypertension were also discovered. Following multidisciplinary panel meetings, liver transplantation was advised due to the severity of the patients symptoms and shunt anatomy.
Furthermore, diagnostic algorithms and other treatment options are discussed

Abernethy malformation: a case report
No full textAbstract Background Abernethy malformation is a very rare congenital vascular malformation defined by diversion of portal blood away from liver. It is commonly associated with multiple congenital anomalies. We present a case of Abernethy malformation, without associated congenital anomalies from India. Case presentation A 5-year-old female child presented with short history of jaundice. A provisional diagnosis of acute viral hepatitis was made in view of clinical presentation and local endemicity of viral hepatitis A. Persistence of jaundice on follow up after 4 weeks led to detailed investigations. Ultrasound and doppler study of abdomen revealed drainage of portal vein into inferior vena cava. CT angiography was performed which confirmed the diagnosis of Type 1 b Abernethy malformation without associated major anomalies. We discuss the common clinical presentations, associated anomalies, diagnostic workup and treatment options of this disorder. Conclusion The treatment of the patients with congenital porto-systemic shunts depends on the site of the shunt, associated congenital anomalies and the extent of liver damage but the prognosis depends on the complications irrespective of anatomical type. However, the extent of associated abnormalities should not deter paediatricians to refer patients for treatment. Whenever possible closure of the shunt should be advised for cure or to prevent complications. Only symptomatic type I patients with absence of possibility to close the shunt may require liver transplant. Long-term follow-up is indicated for all patients.</p
