Q

Source of PIVH or GMH

A

highly vascular germinal matrix is part of the primordial tissue located beneath the ependymal lining of the lateral ventricles

Q

Pathogenesis of PIVH / causes

A

GM watershed zone supply by Heubner’s ( ACA) , lateral striate arteries ( MCA) , anterior choroidal artery ( ICA/ MCA )
1 - hypoxia ➡️ RDS ➡️ ⬇️ o2 metabolic GM active ➡️ ischmic to endothelial cell BV ➡️ infarction ➡️ disruption
2 - ⬆️ co2 ➡️ ⭕️ dilatation BV➡️ sudden 🔺 ⬆️ prefusion ➡️ rupture BV
3- ⬆️ venous pressure ➡️ venous pressure GM ➡️ bleeding 🩸
4- dehydration followed by rapid resuscitation➡️⬆️ intravascular volume ➡️⬆️ BP GM ➡️ rupture

Q

RF PIVH

A

1- ⬆️ CBF & CPP➡️ asphyxia, ⬆️co2 , rapid volume expansion , seizure , pneumothorax, cynotice HD , ventilation , anemia , ⬇️ RBS , A - line , 🩸🔺 BP
2- young GA early preterm 👶 < 32 or late preterm34-36
3- LBW < 1500 g
4- flaiure to give sterile within 48 hr befor preterm delivery
5- APGAR <4 at 1 m , < 8 at 5 m
6-acute amnionitis
7- acidosis
8- coagulopathies
9- GA for CS
10- extracorporeal membrane oxygenation (ECMO): due to heparinization in addition to increased CPP
11- 🤰🏼 cocaine or ASA

Q

Prevention PIVH

A

Avoid preterm delivery 🚚

antenatal corticosteroids

indomethacin vasoconstriction ⬇️ 🔺 CO2 , ⬇️ CBF , ⬆️ o2 ⬇️ PDA
A antenatal vitamin K given IM > 4 hrs prior to delivery decreases PIVH from 33% to 5%

delaying umbilical cord clamping by 30–120 seconds➡️ ⬆️hct,⬇️ PIVH

using surfactant to reduce RDS

  1. minimizing external stimulation

steroids to stabilize the GM vessels

Presentation PIVH

A

Asymptomatic ➡️⬇️ HC , developmental delay , ⬇️ HCT ➡️ 70 % have 6 m survival

Subacute presentation ➡️ irritability, ⬇️ motor activity , abnormal 👀 movement
Acute ➡️
🔺 tone ➡️ decerebrate or decorticate or flaccid paralysis, seizure , tens AF , ⬇️ BP , 🔺Cushing ( apnea,bradycardia)

Q

Pathophysiologic effects of PIVH

A

1- destruction GM
2- direct injury to brain from hematoma ➡️ porencephaly or cystic lesions
3- pressure of hematoma and ⬆️ ICP ➡️⬇️ CBF
4- hypoxia
5- ⬇️CPP periventricular leukomalacia (PVL) and cerebral infarction
6- periventricular hemorrhagic infarction

Q

TX aim

A

Optimize CPP
Normal MAP and pco2
Tx HC

17
Q

Indication for intervention

A

progressive ventriculomegaly
⬆️ ICP split sutures, tense AF

18
Q

Serial lumbar tap

A

10 ml / kg/ tap

temporizing mangment
🚫 < 800 g not tolerated LP alternative ventricular tap

19
Q

VP shunt not reconsider weight less than < 2000g

A

⬆️ infection rate

20
Q

Temporary ventricular access device (TVAD)

A

+➡️ avoid shunt , clear protein and cellular debris, avoid brain penetration,posit for medication , risk of EVD dislodged,25% will not need shunt
- nesurosurgen , infection , csf leak , bleeding, over drainage

21
Q

Serial tap

A

5-20 cc qod to 15 cc TID for tense AF

22
Q

Risk of serial tap

A

⬇️ na

23
Q

Follow up PIVH

A

Serial US on 3rd and 5 days then weekely then bi weekly
CT befor shunt insertion

24
Q

Indication for Vp shunt in PIVH

A

Sx HC
Extubated
Weight > 2000 g
No NEC
CSF protein < 100mg/ dl to avoid blockages

Shunt low or very low pressure
