After 16.5 hours of complex surgery, the medical and surgical team of the Saudi Conjoined Twins Program successfully separated the Tanzanian twins “Nancy and Nice” - marking the program’s 71st successful separation surgery in a humanitarian and medical journey spanning more than 35 years. 🇸🇦🩺

This is a brain artery rupturing in the middle of a angio procedure. You see blood actively leaking into brain. It requires urgent airway and external ventricular drain and is 10/10 scary.

I guess this got enough traction

Cryptogenic cirrhosis with chronic PV occlusions and splenectomy - no good route for PVR/TIPS so percutaneous #mesocaval shunt created by #chogazi @drochohan

Percutaneous trans abdominal esophageal varix embolization was something new.

Technique evolves and a lot to learn with every case.

Only 1.5 months left to The Match
Best of luck!

From 3D imaging to therapy

Using our DISCO tissue clearing and whole organ 3D imaging platform, we revealed skull to meninges microchannels connecting calvarial bone marrow with the brain borders in mice (Cai...Ertürk, Nature Neuroscience,2018, https://t.co/FPimQqPwtg). We then extended this biology to humans, discovering distinct skull bone marrow programs and structural skull meninges connections in health and neurological disease (Kolabas...Ertürk, Cell, 2023).

Now, a new study reports a first therapeutic application of this route: intracalvariosseous (calvarial) injection of drug loaded albumin nanoparticles to “hijack” calvarial immune cells, which then migrate via skull meninges microchannels to CNS lesions, bypassing the blood brain barrier and improving outcomes in stroke models, with encouraging clinical feasibility data (Gao et al., Cell, 2026)

We are proud that DISCO enabled biology that is now turning into concrete therapeutic strategies for devastating neurological diseases. More to come.
