Retrospective Study in 40 Patients of Utility of C-arm FDCT as an Adjunctive Modality in Technically Challenging Image-Guided Percutaneous Drainage Procedures.
To explore the utility of C-arm flat detector computed tomography (FDCT) as an adjunctive modality in technically challenging image-guided percutaneous drainage procedures. ⋯ C-arm FDCT is useful as an adjunctive modality in the interventional suite for technically challenging percutaneous drainage procedures by providing sufficient anatomic detail. Complications of catheter misplacement can be avoided if C-arm FDCT is used prior to tract dilatation. If C-arm FDCT image quality of needle and/or wire placement is poor, conventional CT guidance is recommended.

The Effect of Needle Gauge on the Risk of Pneumothorax and Chest Tube Placement After Percutaneous Computed Tomographic (CT)-Guided Lung Biopsy.
The aim of this study was to evaluate the effect of coaxial guide needle gauge (18 vs. 19 gauge) on the risk of pneumothorax and chest tube placement after CT-guided lung biopsy. ⋯ The use of a 19-gauge coaxial guide needle significantly decreases the risk of pneumothorax and chest tube placement compared with an 18-guage needle.

Case ReportsSelective Embolization of Systemic Collaterals for the Treatment of Recurrent Hemoptysis Secondary to the Unilateral Absence of a Pulmonary Artery in a Child.
The unilateral absence of the pulmonary artery (UAPA) is a rare anomaly. Hemoptysis due to systemic collaterals is one of the most common complications of UAPA. ⋯ Selective embolization of the bronchial systemic collaterals was performed. The patient remained asymptomatic with no recurrence of hemoptysis 8 months after the procedure.

Percutaneous Creation of Bare Intervascular Tunnels for Salvage of Thrombosed Hemodialysis Fistulas Without Recanalizable Outflow.
This study aimed to retrospectively assess the efficacy of a bare intervascular tunnel for salvage of a thrombosed hemodialysis fistula. We examined the clinical outcomes and provided follow-up images of the bare intervascular tunnel. ⋯ Percutaneous creation of a bare intervascular tunnel is a treatment option for thrombosed hemodialysis fistulas without recanalizable outflow in selected patients.

Randomized Controlled Trial Comparative StudyComparison of ultrasound-guided and fluoroscopy-assisted antegrade common femoral artery puncture techniques.
To prospectively compare the procedural time and complication rates of ultrasound-guided and fluoroscopy-assisted antegrade common femoral artery (CFA) puncture techniques. ⋯ Ultrasound-guided technique is faster and safer for antegrade CFA puncture when compared to the fluoroscopic-assisted technique alone.
