Background: Endovascular aneurysm repair (EVAR) has become increasingly prevalent for treating asymptomatic abdominal aortic aneurysms (AAA). This study compares the early and late outcomes between EVAR and open aneurysm repair (OAR) in asymptomatic AAA patients.

Methods: A retrospective observational cohort study was conducted involving 564 patients (445 EVAR, 119 OAR) who underwent AAA repair from January 2010 to June 2022.

Background: This study compared outcomes of endovascular (EVAR) and open aneurysm repair (OAR) in patients with infective native abdominal aortic aneurysms (INAAAs), evaluating perioperative and in-hospital mortality, antibiotic treatment duration, complications, overall survival rates, and reintervention-free times at 10 years.

Methods: A retrospective cohort study of 125 INAAA patients (80 EVAR, 45 OAR) diagnosed between January 2004 and December 2019 was conducted. Patients were categorized as fit or unfit for open surgery based on cardiac, respiratory, and renal status, following the guidelines established in the EVAR-1 and EVAR-2 trials.

Background: Treating an abdominal aortoiliac aneurysm (AAIA) with endovascular methods can be challenging when the internal iliac artery (IIA) is involved. Embolizing the IIA and extending the limb to the external iliac artery (IIAE + EE) to prevent a type 2 endoleak may lead to pelvic ischemic complications. To avoid these complications, strategies that preserve the IIA, such as the bell-bottom technique (BBT) and the iliac branch device (IBD), have been proposed.

Objective: This study was conducted to investigate in vitro proangiogenic and anti-inflammatory phenotypes and functions and the in vivo efficacy and safety of quality and quantity (QQ) media-cultured mononuclear cells (MNCs) compared with standard cultured MNCs from the peripheral blood of patients with chronic limb-threatening ischemia (CLTI) with atherosclerotic risk factors.

Methods: Peripheral blood MNCs (PBMNCs) from patients with CLTI were cultured in QQ culture media or standard culture media. Phenotypic analysis of progenitor cells (CD34CD133), M2 macrophages (CD206), and inactivated T regulatory cells (CD4CD25CD127), colony-forming assay, and tube formation assay of QQ media-cultured MNCs (QQMNCs) and PBMNCs, were conducted.

Objective: The aim of the present study was to investigate the prevalence and predictors of combined >50% iliocaval venous obstruction (ICVO) and superficial venous reflux (SVR) in patients with chronic venous insufficiency (CVI) with a healed (C5) or an active (C6) venous leg ulcer (VLU).

Methods: We conducted a retrospective review of prospectively collected data from patients with CVI with CEAP (Clinical, Etiology, Anatomy, Pathophysiology) class C5 (healed ulcer) or C6 (active ulcer) with SVR who had been treated at our institution from February 2017 to January 2018. The demographic, clinical, and surgical data and duplex ultrasound and computed tomography venography findings were collected.

Background: Infected abdominal aortic and/or iliac aneurysm (AAIA) is a rare condition with a high mortality rate when treated with open surgery. In the past decade, the condition has increasingly been treated with endovascular aneurysm repair (EVAR). However, early and late outcomes, including the continued need for antibiotic treatments and predictors of persistent infection, are poorly understood.

Background: Cyanoacrylate closure (CAC) is a minimally invasive surgery to treat incompetent saphenous veins. This study aimed to investigate the incidence, the risk factors for, and the management of thrombus extension after cyanoacrylate closure (TEACAC) of incompetent saphenous veins in patients with chronic venous disease.

Methods: This retrospective study included patients aged >18 years who were diagnosed with chronic venous disease with superficial venous reflux in the great saphenous vein, anterior accessory saphenous vein, or small saphenous vein, and who were treated with CAC at Siriraj Hospital (Bangkok, Thailand) during January 2017 to December 2018.

Background: Quality and Quantity culture media (QQ culture media) was reported to enhance vasculogenesis and angiogenesis function of mononuclear cells (MNCs) from healthy volunteers. In this study, MNCs from chronic limb-threatening ischemia (CLTI) patients were cultured in QQ culture media, and then investigated for angiogenesis-related phenotype and function.

Methods: Patients aged ≥ 18 years with CLTI caused by atherosclerosis of the lower extremities were prospectively recruited at Siriraj Hospital (Bangkok, Thailand) during July 2017-December 2018.

Objective: Local intramuscular transplantation of granulocyte colony-stimulating factor (G-CSF)-mobilised peripheral blood mononuclear cells (PB-MNC) has been shown to be effective for treating patients with no-option critical limb ischaemia (CLI) who are not considered suitable to undergo surgical bypass or percutaneous transluminal angioplasty. The aim of this study was to investigate the effectiveness and safety of PB-MNCs as a treatment for no-option CLI patients.

Method: This prospective cohort study was conducted between April 2013 and December 2017.

Background: Abdominal aortic aneurysm with severe infrarenal neck angle (>60°) has long been thought to be an obstacle to endovascular aneurysm repair. However, some previous studies reported endovascular aneurysm repair to be safe and efficacious for treating abdominal aortic aneurysm in patients with severe neck angulation. The aim of this study was to investigate the early and late outcomes of endovascular aneurysm repair to treat abdominal aortic aneurysm compared between patients with severe and non-severe infrarenal neck angulation.

Objective: Endovenous radiofrequency ablation (RFA) is one of the most popular techniques for correcting superficial vein reflux. However, the effectiveness of RFA of superficial vein reflux in patients with active or healed venous leg ulcer (VLU) is unknown. Accordingly, the objective of this study was to evaluate the healing rate, the recurrence rate, and the factors significantly associated with healing and recurrence in patients with active or healed VLU who had superficial venous reflux treated with RFA.

Objective A randomized clinical trial was performed to compare the effectiveness of unmarked bandages and customized bandages with visual markers in reproducing the desired sub-bandage pressure during self-bandaging by patients. Method Ninety patients were randomly allocated to two groups ("customized bandages" and "unmarked bandages") and asked to perform self-bandaging three times. The achievement of a pressure between 35 and 45 mmHg in at least two of the three attempts was defined as adequate quality.

Compression bandaging is a major treatment of chronic venous ulcers. Its efficacy depends on the applied pressure, which is dependent on the skill of the individual applying the bandage. To improve the quality of bandaging by reducing the variability in compression bandage interface pressures, we changed elastic bandages into a customised version by marking them with circular ink stamps, applied when the stretch achieves an interface pressure between 35 and 45 mmHg.
