Bleeding In Late Preg Flashcards
-What is late preg
- causes
- dd
- 24:40
- • obs causes ( commen~> less commen)
- abruption
- placenta previa
- vasa previa
•
Gynecological
- vaginal erosion, lesion : as bleeding after sexual intercourse
- bengin or malignant tumour
•
Systemic or general
- anticoagulant as heparin , clexane
- itp
- htn uncontrolled
Dd
Urinary tract bleeding: in severe uti or renal stone
Rectal bleeding: in bleeding piles
Placenta previa
- incidence
- def
- risk factor
- moa
- types
- 2nd most common
- abnormally implanted in lus
1- previous previa
2- + cs : proportion to it especially deeply invaded previa
3- + placental size as in gdm, multifetal
4- + age , parity
5- malpresentation - stretching of lus ( shearing between placenta , lus ) that nay be
• gradully ~>mild reccurent bleeding at 3rd tri
• sudden ~> severe bleeding
- Grade 1 : lateralis ~> > 2cm from os
Grade 2 : marginalis ~> < 2cm
Grade 3 : incomplete centralis ~> partially covering cervix
Grade 4 : complete ~> completely covering
Placenta previa
- cp
- comp
- sym : RECUURENT PAINLESS CAUSELESS bleeding
- general sign : anemia or hypovolemic shock
- abd sign :
fl= amenorrhea
No tender ut
Malpresetations breech or transverse - pv : CONTRA UNTIL PREVIA IS EXCLUDED ( not tvs )
- 1- hge
2- postpartum hge : due to acqired vascularity on lus by placenta , placental fragments
3- PAS (4)
1-
• acreta : adherent to myometrium with plane of cleavage
• increta : invasion to myometrium and short of serosa
• percreta : invasion of myometrium , serosa, othr organs as ub ~> HEMATOURIA
2- diagnosis generally
• us is the gold standard ~> no plane
3- diagnosis on labor
Part of placenta is retained
4- management
Classical cs with hysterectomy increta, percreta
افتح من فوق بالطول اطلع البيبي اقفل واقوم شايلة كل الرحم مينفعش من تحت في invasion
4- fetal comp : + morbidity, mortality due to iugr, massive blood loss
5- increased risk of cs hysterectomy
Previa
- inv
- management
-us : to exclude accidental , know type of previa
- TAS/TVS : is the best to determine type of previa due to best measure of distance between os , placenta
Maternal : cbc , liver , kidney, coagulation progile
Fetal : nst , bpt , ua doppler velocimetry studies, amniotic fluid index
Management
*
Termination if
• reached maturity
• labor pain
• maternal or fetal comp
*Otherwise conservative with steroid to acclerate fetal lung maturity
*Termination by cs except lateralis
*Shock manage
*Comp ttt
Placenta abruption
- incidence
- def
- risk factors
- moa
- types
- the commenst of both ante and intrapartum
- normally implanted
- • pih
• trauma
• ROM with polyhydrominos
• smoking
• APS - In pih : blood ~> inbetween myometrium dissecting it ~> tender hard ut ~> couvelaire( concealed) ~> atong pphge
In trauma ~> normal soft cervix , myometrium) ( revealed )
Types : revealed ( margin) ~>the commenst
Concealed ( center ~> retroplacental hge) ~>Least common but most serious Mixed ~> 2nd most common
Accidental
- cp
- comp
Sym : abd pain with bleeding except in concealed
Genral sign : shock ( hypotension masked by raised bp that soon become hypotension)
Abd : TENDER UT , fl > amenorrhea in concealed
Pv is contra until exclusion
- 1-dic : due to thromboplastin from fetal tissue , massive hematoma ( hypofubringrnmia)
3- couvlaire : in concealed due to retroplacental hge dissecting ut ~> bruise like lesion ~> failure of ut contra , atony
3- sheehan syndrome ( acute necrosis of pituitary gland ) due to severe bleeding
4- HELLP
5- hge
6- fetal comp : + morbidity, mortality due to iugr, iufd
Accidental
- inv
- management
- us : diagnosis of abruption
- speculum : to exclude gynecological ( vaginal erosion ) if abnormal
-Maternal : cbc , liver , kidney, coagulation progile
Fetal : nst , bpt , ua doppler velocimetry studies, amniotic fluid index
Management
*Termination if
• reached maturity
• labor pain
• maternal or fetal comp
* Otherwise conservative with steroid to accelerate fetal lung maturity
* termination by vd unless severe bleeding or cs indications
* shock management
* comp ttt
When tender ut
- accidental hge
- adenomyosis
- septic abortion
What is placental migration
- before 24 w , placenta may migrate on lus but with lus development a relative upward migration occurs with resolution
Vasa previa
(5)
- very rare
- fetal origin
- occur when umbilical cord vessels criss over the internal os as in velamentous insertion of cord or bilobed placenta
- during labor ~> progressive dilation of cervix ~> ruptue , bleeding
- emergency cs
