-
three sections of primative abdomen
-
forgut forms
- pharynx
- lower respiratory
- esophagus
- stomach
- part of duodenum
- liver
- biliary
- panc
-
esophageal atresia
- tracheoesophageal fistula
- abnormal deviation of septum posteriorly
- amniotic fluid cant pass to intestines- poly
-
esophageal stenosis
- narrowing of esophagus
- in distal 3rd
- incomplete recanalization in 8th week
-
lesser sac and peritoneal sac communicate through
epiploic foramen
-
duodenal stenosis/ atresia
- narrowing
- atresia- blockage
- 3rd or 4th part
-
hemopoietic formation in what week
- 6th
- increase liver size in 7th-9th
- kuffer cells
-
biliary atresia
interference of blood supply to ducts and infection
-
cystic fibrosis causes
- echogenic fibrous panc and bowel
- autosomal recessive
- panc disease respiratory problems
-
mid gut forms
- small intestines
- cecum
- cloaca exstrophy
- ascending colon
- transverse colon
- sma blood supply
-
meckels diverticulum
- most common midgut malformation
- remant of prox yolk sac fails to degenerate
- 5cm
- looks like appendix from illeum
-
hind gut
- transverse colon
- desending colon
- sigmoid colon
- rectum
- superior anal canal
- bladder
- urethara
- ima blood supply
-
if no stomach
- esophageal atresia
- disphragmatic hernia
- facial cleft
- cns disorder
- swallowing disorder
- oligo from other causes
-
double bubble
- duodenal atresia
- duodenal stenosis
- annular panc
- ladds bands
- prox jejunal atreasia
- malrotation
- diaphragmatic hernia
-
mass in stomach
placetntal abruption with hematoma formation and hemmorage in amnion
-
meconium
- 15-16th week acuumulates in small intestine
- bile, cells, mucoprotiens
meconium stain- gets into fluid and into lungs
-
large bowel distinct from small bowel at
20 weeks
-
which bowel has peristalsis
small
-
-
what lobe bigger
- left due to increased o2 in blood
- revereses at birth
-
liver enlarges with
rh immune disease from increased blood production
-
most common hepatic tumor
- hemangioendothelioma
- rare
- symptomatic and vascular
- can cause immune hydrops
-
-
what situs is more severe
partial
-
-
asplenia
- no spleen
- midline stomach and gb
- more central liver
- so and ivc on same side
- 90-95% death
-
poly spelenia
- more than one spleen
- liver spleen and stomach transposed no gb
- 2 spleens at greater curve of stomach
- 80% death
-
cardiac malformations more common in which situs
asplenia
-
pseudo ascites
- GI obstruction- bowel perforation
- non GI- immune and non immune hydrops, UT obstruction, infection, abd tumor
-
pseduo ascites never
outlines falciform ligament like true ascites
-
cholelitiasis
- stones common in fetus
- resolve in utero ir childhood
- often in high fat diet of premie
-
choledocal cysts
- dilated bile duct
- gb more aterior than duodenum and cyst near gb (bile duct)
-
agenisis of gb in how many cases
20%
-
spleen and liver enlarge in fetus with
rh immune disease
-
esophageal atresia occurs in
1 in 2500 births
-
30% of fetuses with duodenal atresia have
trisomy 21
-
surgery after birth with duod atreasia to
connect stomach to jejunm bypass obstruction
-
what is more common than dudodenal atresia
jejunum illeum or both atresia or stenosis
-
the more distal the bowel obstruction
the less severe the hydraminos and the later it develops
-
echogenic bowel
downs tris 21
-
normal colon increases diameter after 23 weeks but never over
18mm
-
meconium ileus
- small bowel disorder
- thick meconium in distal ileum
- earliest manifest of cystic fibrosis
-
anorectal atresia
- membrane covers anus
- poor prognosis from associated anomolies
-
Hirschsprungs disease
mega colon
-
meconium peritonitis
hydramonis
- sterile peritonistis from bowel perforation
- calcifications with cystic fibrosis
-
hyperechoic bowel
- 2nd trimester
- decreased water content
- hypoperistalsis
- 3 grades
- mild, moderate, very echogenic
-
ascites
- cyst like appearence of abdomen from fluid between unfused omentum
- bowel perforation
- bladder rupture
- outlines falciform ligament
-
cystic masses of abdomen
only a problem in compress organs
