KLA had a series of characteristic intra-abscess features; septal breakage, turquoise-like structure, hairball-like content, air-fluid level, and no enhanced rim. When turquoise/hairball sign or air-fluid level is present in abscess, KLA would be a probable diagnosis in the clinical field.

The Angio-Seal is a widely used arterial closure device that helps achieve faster hemostasis and provide early ambulation to patients. However, it can cause various complications in clinical practice. We present the uncommon complication of popliteal artery occlusion following Angio-Seal deployment, and describe an effective interventional approach to its treatment. Because fluoroscopy-guided Fogarty embolectomy has the advantages of complete removal of the embolus without fragmentation, and clear visualization of the exact location of the embolus during the procedure, it is a suitable method for treating this complication.

We describe a simple but useful technique for improving the visualization of the needle during ultrasound-guided percutaneous nephrostomy, especially suitable for obese patients.
