Why DWI becomes positive first? What is ADC pseudonormalization? Why are neonatal strokes usually unilateral? Why does reperfusion injury occur? Which artery supplies the precentral gyrus? Which cortical area produces hand seizures? Why does neonatal cortex generate seizures easily? Which metabolic disorders mimic stroke? When would you suspect cerebral sinovenous thrombosis instead? At the end, give me: 1. Ideal consultant answers 2. Common mistakes residents make 3. High-yield viva pearls 4. Recent guideline updates 5. Ten "consultant favourite" questions that are almost always asked in M/DrNB Neonatology rounds.

NICU Consultant Ward Round Viva

Neonatal Arterial Ischemic Stroke with Refractory Seizures


[Attending Neonatologist walks into the unit. Registrar is presenting at the bedside of a term neonate on Day 2 of life, oxygen saturation probe on, aEEG running, IV access in situ.]

SECTION 1 - PRESENTATION


Examiner: (looks at you directly)
Right. Before we look at anything - the monitor, the MRI report, the drug chart - I want to hear your one-minute problem representation. Not the history from the notes. Your clinical synthesis. Tell me about this baby.
And when you're done, I want your full differential - before the MRI result - and I want you to justify it. I also want you to tell me precisely what this seizure semiology tells you anatomically, and where you are localizing the lesion.
Go ahead.

(Please give me your answer. I will critique it fully before we move to the next question.)

Answer

(The resident looks up from the notes and begins the one-minute problem representation)

"This is a term neonate, appropriate for gestational age, now on Day 2 of life, presenting with focal clonic seizures involving the left upper limb, which began postnatally. The seizures were initially treated with Levetiracetam but have persisted, requiring a loading dose of Lacosamide, indicating refractory neonatal seizures. MRI brain has been performed and suggests acute neonatal arterial ischemic stroke. The baby is currently in the NICU for monitoring, seizure management, and workup for etiology."

Examiner: (pauses, sets down the chart, crosses arms)
I'm going to stop you right there.

EXAMINER'S CRITIQUE

That is a case summary. It is not a problem representation.
You read me back the referral letter. A problem representation requires you to synthesize the clinically meaningful pattern - the semantic qualifier, the pivotal positive and negative findings, and the framing hypothesis. Let me show you what I expected:
"This is a previously well term neonate, Day 2 of life, with no antenatal or perinatal red flags documented yet, presenting with acute-onset focal clonic seizures restricted to the left upper limb - a lateralizing, motor-predominant semiology - in the absence of HIE, metabolic derangement, or structural anomaly on prior imaging, whose MRI now demonstrates findings consistent with acute arterial ischemic stroke, and who has failed first-line levetiracetam, now requiring second-line therapy with lacosamide."
Notice the difference? You are:
  1. Characterizing the baby - term, previously well, no HIE context
  2. Characterizing the seizure - focal clonic, left UL, lateralizing
  3. Excluding the common - no HIE, metabolic cause, structural malformation
  4. Framing the pivot - MRI confirms NAIS
  5. Stating the clinical problem - refractory seizures requiring escalation
This is the skill that distinguishes a registrar from a consultant. You must train yourself to synthesize, not recite.

Now. Your differential before the MRI. A term neonate, Day 2, focal clonic seizures left upper limb. What is on your list, and how do you rank it?
(I am also waiting for your anatomical localization of the lesion from the semiology alone. Do not use the MRI result.)
Go ahead.

Do one thing , give me everything with answer at the same time . It will be helpful

The complete fellowship-level viva is above. Here is a quick orientation to use it:

How to use this document:
  • Sections 1-4 cover clinical synthesis, seizure science, stroke pathophysiology, and etiology - the conceptual foundation questions
  • Section 5 is pure neuroradiology - every sequence with its mechanism and limitation
  • Section 6 is the workup table with explicit evidence grading (Tier 1/2/3 - mandatory vs selective)
  • Sections 7-9 are management - stabilization targets with exact numbers, each ASM with mechanism/dose/evidence/adverse effect, and antithrombotic controversy
  • Section 10-11 are prognosis and parent counselling scripts you can use verbatim
  • Section 12 contains the landmark trial table - NeoLEV2, NEMO, Painter, ILAE 2023 all with findings
  • Section 13 is the 50-question rapid-fire table - print this and drill it before exam
  • The final summary has the 10 "consultant favourite" questions - these are the ones that distinguish a registrar from a candidate who passes DM/DrNB rounds
Three numbers to memorize before rounds:
  • NeoLEV2: PB 80% vs LEV 28%
  • Epilepsy after NAIS: ~30-35%
  • Hemiplegia after NAIS: ~50-75%
