▶ Ep 3 · 13:00
ETV failures occur through four mechanisms: ostomy closure, ostomy narrowing, patent ostomy with membrane formation elsewhere in the third ventricle or basilar cisterns, or insufficient CSF diversion possibly due to mixed communicating hydrocephalus.
clinical · Congenital Aqueductal Stenosis
▶ Ep 3 · 18:00
If a clinician is not comfortable letting a patient go for two weeks without follow-up ultrasound or examination, that is a red flag warning sign that the patient needs shunting rather than continued observation.
opinion · Congenital Aqueductal Stenosis
▶ Ep 2 · 5:00
Serial slow dilation with balloon catheters (such as 3 French Fogarty catheters) can successfully open the majority of the accessible floor of the third ventricle, even in patients with narrow third ventricles.
clinical · Hydrocephalus
▶ Ep 2 · 9:00
The ETV Success Score assigns 30 points for aqueductal stenosis etiology and 50 points for age greater than 10 years, with points translating directly to percentage success rates.

▶ Ep 3 · 0:16
epidemiological Congenital aqueductal stenosis accounts for 5-20% of congenital hydrocephalus etiology, with approximately 600-1500 cases per year in the United States. ↗
▶ Ep 3 · 2:00
clinical Walter Dandy in the 1920s used a crude cystoscope to burn choroid plexus in hydrocephalic patients, with 24 out of 25 patients dying of complications. ↗
▶ Ep 3 · 3:00
clinical Dr. Mixer in 1923 is credited with the modern version of ETV involving fenestration of the floor of the third ventricle using a urethroscope. ↗
▶ Ep 3 · 3:30
clinical Scarf et al. in 1936 published a series of 20 ETV cases with 10 showing long-term improvement, 7 failures, and 3 immediate post-surgical deaths. ↗
▶ Ep 3 · 4:00
clinical ETV technology reached its modern form in the 1980s with advances in camera and endoscope technology, after being relatively quiescent from the mid-1930s due to the invention of VP shunt pressure-regulated valves in the 1950s. ↗
▶ Ep 3 · 5:00
clinical Serial slow dilation with balloon catheters (such as 3 French Fogarty catheters) can successfully open the majority of the accessible floor of the third ventricle, even in patients with narrow third ventricles. ↗
▶ Ep 3 · 6:00
opinion Making the ETV ostomy as large as possible is important in young children because it helps fight against closure in the growing infant brain. ↗
▶ Ep 3 · 9:00
clinical The ETV Success Score assigns 30 points for aqueductal stenosis etiology and 50 points for age greater than 10 years, with points translating directly to percentage success rates. ↗
▶ Ep 3 · 10:00
clinical Patients with aqueductal stenosis who are greater than 10 years old have an 80% chance of ETV success, while those less than 1 month old have success rates in the 30-50% range. ↗
▶ Ep 3 · 10:30
clinical ETV procedures carry risks including hemorrhage, injury to the basilar artery, damage to the fornix (which can cause memory loss), and procedure failure. ↗
▶ Ep 3 · 12:00
clinical Successful ETV patients typically do not show the same degree of ventricular reduction as shunted patients, but developmental outcomes can be very good. ↗
▶ Ep 3 · 12:30
clinical A visible CSF jet stream (appearing black on sagittal MRI) through the ETV ostomy is a reassuring sign of patency, though not required for success. ↗
▶ Ep 3 · 13:00
clinical ETV failures occur through four mechanisms: ostomy closure, ostomy narrowing, patent ostomy with membrane formation elsewhere in the third ventricle or basilar cisterns, or insufficient CSF diversion possibly due to mixed communicating hydrocephalus. ↗
▶ Ep 3 · 17:30
clinical If an ETV works and shows success at 6 months to 1 year, very few patients will have long-term delayed complications, unlike the constantly ticking time bomb of shunt dependency. ↗
▶ Ep 3 · 18:00
opinion If a clinician is not comfortable letting a patient go for two weeks without follow-up ultrasound or examination, that is a red flag warning sign that the patient needs shunting rather than continued observation. ↗
▶ Ep 3 · 18:30
clinical Stented ETV using hardware to hold the ostomy open has not panned out well because foreign body reactions can occur at any time in the patient's life, similar to shunt failures. ↗
