Purpose: To review the available safety and efficacy data for prostatic artery embolization (PAE) in the treatment of benign prostatic hyperplasia (BPH).
Materials And Methods: PubMed was searched for publications that included PAE for the treatment of BPH through May 2015. Two independent reviewers determined the appropriateness for inclusion of each article and compiled data by using pooled weighted means and standard deviations.
Results: The literature search identified 161 articles, of which 7 studies, with a total of 562 patients, met all inclusion/exclusion criteria. PAEs were performed bilaterally in 85% of patients, unilaterally in 12%, and unsuccessfully in 3%. International Prostate Symptom Score decreased from 24.51 ± 6.12 at baseline to 10.42 ± 5.39 at 6 months. Quality of life score decreased from 4.76 ± 0.98 at baseline to 2.51 ± 1.13 at 6 months. Peak urinary flow rate increased from 8.41 mL/s ± 2.63 at baseline to 15.44 mL/s ± 5.64 at 6 months. Postvoid residual measurement decreased from 105.94 mL ± 76.77 at baseline to 39.57 mL ± 15 at 6 months. Prostate-specific antigen level decreased from 4.79 ng/mL ± 5.42 at baseline to 3.16 ng/mL ± 1.5 at 6 months. None of these parameters showed clinically significant changes from 6 months to 12 months. Total prostate volume decreased from 96.56 cm3 ± 35.47 at baseline to 46.73 cm3 ± 20.51 at 12 months. There were 200 minor complications and 1 major complication.
Conclusions: PAE improves lower urinary tract symptoms caused by BPH, with a favorable short- to midterm safety profile.

Mid-term outcomes of double-balloon technique for balloon aortic valvotomy: Experience from a tertiary care center in India.
Ann Pediatr Cardiol
November 2024
Department of Pediatric Cardiology, Amrita Institute of Medical Sciences, Kochi, Kerala, India.
Article Synopsis
- The study investigates the double-balloon technique's effectiveness in reducing aortic regurgitation (AR) after balloon aortic valvotomy (BAV) in children, with a focus on short- and mid-term outcomes.
- Out of 50 patients (average age 6.5 years), 34% had prior AR, and after the procedure, there was a significant decrease in peak-to-peak gradient and only 20% experienced trivial AR post-BAV, while none had severe AR.
- The technique was found to be safe, with no deaths or emergency surgeries required, suggesting it could be a promising alternative for larger patients, although further long-term studies are needed.
Impact of Arch Disease Pathology on Outcomes of Zone 0 Branched Thoracic Endovascular Arch Repair.

Objective: Zone 0 branched thoracic endovascular arch repair (Z0BTEVAR) has emerged as an alternative to open repair for high-risk patients with aortic arch pathology. However, it is unclear how disease characteristics in this population impacts clinical outcomes. The study aimed to compare Z0BTEVAR according to arch disease pathology and to identify potential predictors of post-operative outcomes.

This study aims to give a comprehensive overview of the one anastomosis gastric bypass (OAGB) and Roux-en-Y gastric bypass (RYGB) during 5 years of follow-up in terms of weight loss, the remission of obesity-associated diseases and complications. We performed a retrospective cohort study, with a 1:1 propensity-score matched (PSM) comparison between all adult patients who underwent a primary OAGB or RYGB in 2016. Patients with a body mass index (BMI) ≥50 kg/m were excluded.

Department of Cardiovascular Surgery, Sapporo Medical University, Sapporo, Japan.
Purpose: Previous clinical studies have reported on the short- and mid-term prognoses of thoracic endovascular aortic repair (TEVAR) using the GORE thoracic aortic graft (TAG) or conformable GORE TAG. We evaluated the long-term prognoses of patients who underwent TEVAR using the GORE TAG or conformable GORE TAG in a real-world setting.
Materials And Methods: This retrospective observational study analyzed the data of all consecutive patients aged 20 years or older who underwent TEVAR using either the GORE TAG or the conformable GORE TAG at a single center.

Department of Vascular Surgery, First Medical Center of PLA General Hospital, Beijing, China.
Purpose: Previous studies have indicated mixed short-term outcomes between drug-coated balloon (DCB) angioplasty and percutaneous transluminal angioplasty (PTA) in the treatment of infrapopliteal lesions. However, the long-term durability of DCB angioplasty remains uncertain. The objective of this study is to present the long-term outcomes of DCB angioplasty for infrapopliteal lesions in patients with critical limb ischemia (CLI).
