PUMCH: Minimalist Bent-Needle Technique Resolves Recurrent Post-Vitrectomy Hemorrhage

🩸 Diagnostic Dilemma
Recurrent vitreous hemorrhage after vitrectomy is a universal challenge in retinal surgery.
Traditional management often requires a traumatic and costly secondary vitrectomy.
For pediatric patients, conservative observation is excessively slow and severely impairs visual development.

⚙️ Surgical Nuances
The ophthalmology team at Peking Union Medical College Hospital (PUMCH) developed an original bent-needle vitreous cavity lavage to break this dilemma.
As shown in the attached images, the procedure is performed in a supine position using a 25G bent needle combined with a contralateral 30G infusion needle.
The ingenious bending angle allows the drainage needle to be naturally self-retaining against the globe, enabling smooth gravity-assisted drainage.

💡 Clinical Pearls
The core advantage of this trick is replacing a complex secondary surgery with a rapid and ultra-low-cost alternative.
The entire lavage takes only 1 to 2 minutes under local anesthesia.
Postoperatively, there is no gas bubble interference, fundus examination remains unhindered, and the patient requires absolutely no special positioning.

🔬 Take-home Message
Ultimate clinical practicality often stems from minor modifications to conventional instruments.
This technique resolves a complex clinical pain point with minimal anatomical intervention and has been published in the prestigious journal RETINA.
It provides a highly valuable new perspective for outpatient management in resource-limited settings globally.
