Article Abstract
Background: Adrenal vein sampling (AVS) is the preferred method for subtyping patients with primary aldosteronism, while the procedure is technically challenging. This study evaluated the feasibility and effectiveness of a single-catheter approach for AVS.
Methods: A retrospective analysis of 106 consecutive patients who underwent AVS was performed to determine the procedural success and complication rates. Bilateral AVS procedures were performed using a single 5-Fr Tiger catheter with repeated manual reshaping.
Results: We successfully advanced the catheter into the bilateral adrenal veins of all patients and reached a 90.6% procedural success rate of AVS. The procedural period was 33.0 ± 8.2 min, the fluoroscopy period was 5.8 ± 1.7 min, and the diagnostic contrast used was 17.3 ± 5.5 ml. Only one patient (0.9%) had a hematoma at the femoral puncture site. No other complications were observed. The operation period gradually shortened as the cumulative number of operations increased. The number of procedures required to overcome the learning curve was about 33 cases.
Conclusions: The single-catheter approach is feasible and effective for AVS. Moreover, this approach required a relatively short learning curve for an inexperienced trainee.

Laser-interstitial thermal therapy (LITT) is a minimally invasive technique used in neurosurgery for ablation of epileptic foci and malignant lesions, especially for glioma located in regions that pose high surgical risk. Current research mainly focuses on maximizing the safety of the procedure and proving the non-inferiority compared to open resection of glioma. However, data regarding the current applicability in real-time cohorts are lacking.

Background: Pulsed field ablation (PFA) is a novel non-thermal energy source. Recently, we developed a tailored and streamlined pulmonary vein isolation (PVI) approach utilizing a pentaspline PFA catheter via a single access, single catheter approach. This study was aimed at comparing safety, efficacy, and follow-up of this approach with a conventional approach.

Background: Retrobulbar hematoma after blowout fracture surgery is a devastating complication that can lead to permanent vision loss. When such complications occur, emergency interventions like lateral canthotomy are often required, resulting in additional tissue trauma. This study presents a novel dual-catheter drainage technique designed to prevent postoperative orbital hematoma formation.
