Purpose: To analyze the safety and efficacy of additional venous leak embolization after an initial arterial revascularization to treat patients with combined arteriogenic and venogenic erectile dysfunction (ED).

Materials And Methods: Single-center observational study from October 1, 2019, to September 30, 2022, including 26 patients with ED resistant to phosphodiesterase-5-inhibitors (PDE5i) and without significant clinical benefit after arterial revascularization of erection-related arteries. Additional treatment with venous leak embolization was performed 458 ± 424 days after arterial revascularization.

Background: We hypothesized, that endovenous laser ablation (EVLA) with the highly water specific 1940-nm wavelength laser would reduce ablation-related thrombus extension (ARTE) incidence compared to the less specific 1470-nm laser.

Materials And Methods: Between February 2017 to March 2023 we identified a consecutive series of patients undergoing EVLA from the prospectively ongoing VEINOVA registry. Patients were treated with the 1940-nm or 1470-nm laser.

Current evidence indicates that erectile dysfunction (ED) is an independent risk factor for future cardiovascular events. This study aimed to estimate the cost-effectiveness of screening and subsequent preventive treatment for cardiovascular risk factors among men newly diagnosed with ED from the Swiss healthcare system perspective. Based on known data on ED and cardiovascular disease (CVD) prevalence and incidence costs and effects of a screening intervention for cardiovascular risk including corresponding cardiovascular prevention in men with ED were calculated for the Swiss population over a period of 10 years.

Traditionally, varicose vein treatment is predominately performed during the colder seasons. However, data whether higher outdoor temperatures affect the outcome and/or complication rate of endovenous thermal ablation (ETA) for treatment of symptomatic varicose veins are missing. In this observational study, the medical records of all patients who had ETA of the great saphenous vein (GSV), accessory saphenous vein (ASV), or small saphenous vein (SSV) between September 2017 and October 2020 were reviewed.

Atherosclerotic disease of erection-related arteries is a major reason for erectile dysfunction (ED). Lp(a) has been implied in the pathophysiology of atherosclerosis in the coronary and lower limb arteries. Here, we investigated if Lp(a) plays a specific role in ED due with symptomatic pelvic artery atherosclerosis.

Background: Recurrent varicose veins with neovascularization are a common clinical problem. Although endovenous laser ablation (EVLA) has become the standard treatment modality to treat truncal veins, additional sclerotherapy is required to treat newly formed tortuous veins. A novel laser fiber with an injection channel (nLF) allows for such simultaneous proximal sclerotherapy and offers a potentially more effective treatment option.

Purpose: This all-comers registry aimed to assess safety and early efficacy of venous embolization in patients with venogenic erectile dysfunction due to venous leak in an unselected cohort.

Methods: Between October 2019 and September 2022, patients with venogenic erectile dysfunction resistant to phosphodiesterase-5-inhibitors were treated with venous embolization using ultrasound-guided anterograde access via a deep dorsal penile vein in a single center. A mix of ethiodized oil and modified cyanoacrylate-based glue n-butyl 2 cyanoacrylate (NBCA) monomer plus methacryloxy-sulpholane monomer (Glubran-2, GEM, Italy) was used as liquid embolic agent.

: The extent of arterial disease in patients with erectile dysfunction (ED) non-responsive to intracavernosal injection of Alprostadil is of importance for therapeutic options. However, published evidence, in particular angiographically validated is scarce. Here we investigated arterial lesion patterns in this specific patient cohort by selective angiography.

Article Synopsis
  • The study investigates the practices of thromboprophylaxis and follow-up protocols among physicians in Switzerland performing endovenous thermal ablation (ETA) for truncal varicose veins, emphasizing the increasing global adoption of this treatment.
  • A survey sent to 193 ETA-certified physicians yielded a 62.7% response rate, revealing that most practitioners use pharmacologic thromboprophylaxis, primarily direct oral anticoagulants, immediately post-procedure for varying durations.
  • The results also show that nearly all physicians (99.2%) routinely perform post-ablation duplex ultrasonography, with many conducting multiple follow-up scans to monitor for potential complications like endovenous heat-induced thrombosis.

Objective: The optimal ablation distance from the catheter tip to the common femoral vein during endovenous laser ablation (EVLA) of the great saphenous vein (GSV) is a matter of debate. In this study, we evaluated the feasibility and safety of flush ablation (fEVLA) of the GSV.

Methods: This single-center, retrospective analysis of prospectively collected data included all consecutive fEVLA interventions of the GSV between September 2017 and October 2018.

Aim Of The Study: The objective of this study was to identify the optimal duration of pharmacological thromboprophylaxis after outpatient endovenous laser ablation (EVLA).

Methods: In this multicentre retrospective study in a university hospital, regional hospital and private practices, we collected the demographic, procedural and outcome data of all consecutive patients with varicose veins class C2 to C6 undergoing outpatient EVLA of truncal and accessory veins between February 2009 and December 2015. The cumulative primary efficacy endpoint consisted of endovenous heat-induced thrombosis (EHIT) class 2–4, deep vein thrombosis (DVT) and pulmonary embolism (PE) diagnosed with duplex ultrasound or computed tomography angiography after 1 and 4 weeks of follow-up.

Article Synopsis
  • The study aimed to assess the safety and effectiveness of endovenous laser ablation (EVLA) for treating varicose veins in patients aged 75 and older.
  • Data was collected from 829 patients, comparing outcomes between those under 75 and those 75 and older, focusing on complete vein ablation and instances of complications like thrombosis and bleeding.
  • Results showed similar efficacy and low complication rates between the two age groups, suggesting that EVLA is both effective and safe for elderly patients in an outpatient setting.

Rapid estimates of the central venous pressure (CVP) can be helpful to administer early fluid therapy or to manage cardiac preload in intensive care units, operating rooms or emergency rooms in order to start and monitor an adequate medical therapy. Invasive CVP measurements have inherent and non-negligible complication rates as well as great expenditures. Several noninvasive methods of CVP measurements, like ultrasound-guided techniques, are available, but require trained skills and special equipment which might not be at hand in all situations.

We report a case of a 56-year-old male patient with a life-threatening left common femoral artery bleeding due to tumor erosion. The patient had a history of advanced high-grade pleomorphic leiomyosarcoma of the left groin with pulmonary metastasis. Clinical examination revealed a massive tumor bulking at the left groin with necrosis and phleb- and lymphedema.

Lymphedema is a chronic, progressive, and common but often unrecognized condition. The diagnosis of lymphatic disease on clinical grounds alone remains a challenge. Without proper diagnosis, therapy is often delayed, allowing disease progression.
