Placenta Accreta Spectrum — When the Placenta Refuses to Let Go (OBGYNX 2025 Edition)

Intro — The Clingiest Relationship in Medicine

Most placentas know how to detach.

This one?

This one shows up with emotional baggage and a drill.

Placenta Accreta Spectrum (PAS) is when the placenta invades too deeply into the uterus —

sometimes through it — like it missed the concept of boundaries in embryology class.

And the worst part?

You won’t know it’s there until the OR looks like a Quentin Tarantino scene.

🔹

Step 1: The Family Tree of Horror

Mnemonic: “A-I-P = Attached, Invasive, Perforating.”

• Accreta: Placenta adheres to the myometrium.
  (Like Velcro — hard to peel, but possible.)

• Increta: Placenta invades into the myometrium.
  (Like a bad tenant drilling into the walls.)

• Percreta: Placenta perforates through the uterus and into nearby organs (hello, bladder).
  (At this point, everyone in the OR panics in 4K.)

💬 OBGYNX humor:

If the placenta’s trying to shake hands with the bladder, that’s not “friendly,” it’s “percreta.”

🔹

Step 2: The Risk Factors — Who Invited the Drama?

Mnemonic: “SCARFACE.”

S — Scars from previous C-sections

C — Curettage or uterine surgery

A — Advanced maternal age

R — Repeat placenta previa

F — Fibroids (especially lower segment)

A — ART (assisted reproduction)

C — Cesarean hysteria history

E — Endometrial damage

In short:

“If the uterus has been through stuff — expect trouble.”

💡 OBGYNX pearl:

“Every C-section is a love letter from the placenta to your next pregnancy.”

🔹

Step 3: The Ultrasound Signs — When the Placenta Starts Acting Weird

You’ll know when you see it.

The image doesn’t lie — it screams.

1. Loss of the clear retroplacental zone.

The normal smooth interface between placenta and uterus disappears — like a missing safety line.

2. Thinning of myometrium (<1 mm).

When the wall looks paper-thin, it’s not shy — it’s invaded.

3. Placental lacunae (a.k.a. “Swiss cheese sign”).

Irregular, turbulent, scary black lakes inside the placenta.

They look peaceful until you turn on Doppler — then it’s Niagara Falls.

4. Bridging vessels.

Color Doppler shows vessels crossing from placenta into bladder.

That’s your “call the team NOW” moment.

5. Bulging of uterine contour.

If the uterus looks pregnant and possessed — that’s percreta.

Mnemonic: “L-T-L-B-B = Lost zone, Thin wall, Lacunae, Bridging, Bulging.”

💬 OBGYNX humor:

If your Doppler looks like Christmas lights inside the bladder, it’s not festive — it’s fatal.

🔹

Step 4: The MRI — Because Sometimes You Need the Sequel

MRI is for when ultrasound says:

“Something’s wrong, but I’m too polite to describe it.”

MRI helps confirm invasion depth and bladder involvement.

Look for dark intraplacental bands and uterine bulging.

OBGYNX line: “MRI — because sometimes you just need a second opinion from physics.”

🔹

Step 5: The Clinical Clues — The Placenta That Never Says Goodbye

Classic story:

• Patient with previous C-sections.

• Placenta previa or low-lying.

• At delivery, placenta refuses to separate.

• Bleeding starts like an action movie.

Mnemonic: “The 3 D’s — Dense, Deep, Deadly.”

Dense adherence, Deep invasion, Deadly bleeding.

🔹

Step 6: The Management — Think Before You Touch

Rule number one: Do not pull.

You’re not delivering the placenta — you’re summoning chaos.

Mnemonic: “If It Sticks, Stop!”

• Suspected Accreta → Planned C-section + hysterectomy (preferably with a calm, caffeinated team).

• Blood ready. Like, a lot of it.

• Urology on standby if bladder is involved.

• No manual removal attempts.

• Conservative management only if patient stable + wants future fertility + expert center.

💡 OBGYNX truth:

“If you think it’s accreta and still pull — you’re not delivering, you’re detonating.”

🔹

Step 7: The Surgical Theater — The Moment of Truth

You walk in. The placenta stares back.

Anesthetist sweating.

Urologist lurking.

Everyone pretending they’re fine.

If you see:

• Placenta bulging through the lower segment,

• Bladder invaded,

• Or bleeding that defies physics —

you know it’s that case.

💬 OBGYNX line:

“If the bladder is crying blood and the uterus looks possessed — it’s not postpartum hemorrhage, it’s percreta.”

🔹

Step 8: The OBGYNX Mnemonics — Because Panic Needs Structure

“STUCK.”

S — Scarred uterus

T — Thin myometrium

U — Unclear retroplacental zone

C — Crazy Doppler

K — Keep your hands off

And the survival mantra for residents:

“If it looks accreta, don’t be a hero — be a witness.”

⚠️

Step 9: The Scary Truth (and Why You Still Need Humor)

Placenta accreta spectrum is one of the top three causes of maternal mortality globally.

It’s not rare anymore — it’s the new “frequent flyer.”

So yes, it’s terrifying.

But laughter gives you oxygen in chaos — and you need oxygen to think.

That’s why OBGYNX teaches with sarcasm: because if you can laugh at the fear, you can control it.

“Scan with precision. Plan with caution. Deliver with respect.”
