Purpose: Transjugular intrahepatic portosystemic shunt (TIPS) creation is used to treat portal hypertension complications. Often the most challenging and time-consuming step in the procedure is the portal vein (PV) puncture. TIPS procedures are associated with prolonged fluoroscopy time and high patient radiation exposures. We measured the impact of transabdominal ultrasound guidance for PV puncture on duration of fluoroscopy time and dose.
Methods: We retrospectively analyzed the radiation dose for all TIPS performed over a four-year period with transabdominal ultrasound guidance for PV puncture (n=212, with 210 performed successfully and data available for 206); fluoroscopy time, dose area product (DAP) and skin dose were recorded.
Results: Mean fluoroscopy time was 12 min 9 s (SD, ±14 min 38 s), mean DAP was 40.3±73.1 Gy·cm2, and mean skin dose was 404.3±464.8 mGy.
Conclusion: Our results demonstrate that ultrasound-guided PV puncture results in low fluoroscopy times and radiation doses, which are markedly lower than the only published dose reference levels.

Optimized workflow with hybrid (very) high-power short-duration radiofrequency ablation renders point-by-point pulmonary vein isolation as fast and effective as cryoballoon ablation.

Introduction: A hybrid approach with very high-power short-duration (vHPSD) posteriorly and ablation-index guided HPSD (50 W) anteriorly seems to be an optimal balance between efficiency and effectiveness for point-by-point pulmonary vein isolation (PVI). The aim of the current study is to compare vHPSD/HPSD ablation to cryoballoon ablation (CBA) in patients with symptomatic atrial fibrillation (AF).
Methods And Results: In this retrospective single-center study, we identified 110 consecutive patients who underwent their first PVI with either vHPSD/HPSD (n = 54) or CBA (n = 56).
The US4ABL Strategy: A Systematic Ultrasound-Guided Approach for Left Atrial and Ventricular Ablation Procedures.

: The safety and efficacy of electrophysiological (EP) procedures using ultrasound (US) guidance are being increasingly studied. We investigated if a systematic workflow with ultrasound guidance (the US4ABL), comprising four steps (transesophageal echocardiography (TEE) for left atrial thrombus exclusion, US of the groin vessels to guide femoral access, TEE-aided transseptal puncture, and transthoracic echocardiography (TTE) for exclusion of pericardial tamponade after the procedure), reduces the number of complications and fluoroscopy duration and dose. : A total of 212 consecutive patients underwent left-sided ablations using the US4ABL workflow and were compared to a group of 299 patients who underwent the same type of ablations using post-procedural TTE to exclude tamponade (standard group: venous and/or arterial access by palpation and fluoroscopy, and pressure guided transseptal puncture).

Objective: To determine the feasibility, yield, and safety of fluoroscopic-guided aspiration of the acutely dislocated total hip arthroplasty (AD-THA).
Materials And Methods: IRB-approved, retrospective review of fluoroscopic-guided aspirations of AD-THA (January 2005-December 2023) was performed. Data from electronic charts and fluoroscopy images/reports were obtained.
The comparative efficacy and safety of Tiger II versus judkins catheters in coronary angiogram via the radial artery access: a meta-analysis.

Department of Cardiovascular Medicine, Yale University School of Medicine, New Haven, CT, USA.
Background: Trans-radial coronary angiogram (TR-CAG) has gained popularity due to lower complication rates compared to transfemoral access. Operators can use either conventional catheters, such as Judkins, or single dedicated catheters, such as Tiger-II. This meta-analysis compared the safety and efficacy of Tiger-II versus Judkins catheters in TR-CAG.

Background: An all-inside endoscopic flexor hallucis longus (FHL) tendon transfer is indicated for the treatment of chronic, full-thickness Achilles tendon defects. The aim of this procedure is to restore function of the gastrocnemius-soleus complex while avoiding the wound complications associated with open procedures.
Description: This procedure can be performed through 2 endoscopic portals, a posteromedial portal (the working portal) and a posterolateral portal (the visualization portal).
