Although open repair remains the mainstream treatment for aortic arch dissection, its surgical complexity and perioperative complications are significant. We developed a novel stentgraft system for less-invasive endovascular aortic arch repair. We successfully performed a total percutaneous transfemoral endovascular repair of aortic arch dissection using a novel off-the-shelf endograft system.

- Balloon dilation followed by covered balloon-expandable stent (CBS) implantation is shown to be a highly effective treatment for improving blood flow in patients with coarctation of the aorta (CoA), achieving a 100% procedural success rate in a recent meta-analysis.
- The analysis included 12 studies with 411 patients and found significant improvements in pressure gradients and systolic blood pressure after the procedure, along with low overall complication rates.
- Subgroup results indicated that certain stent types, like BeGraft, were associated with higher complications related to access sites, but overall, CBS implantation is deemed safe and effective for CoA treatment.
Renal cortical blood perfusion CEUS can evaluate the structure and microcirculation of renal cortex, which is expected to provide a safer and more convenient evaluation system for clinicians in the diagnosis and treatment of early renal artery disease.

Article Synopsis
- Compression therapy is gaining recognition in treating lower extremity venous diseases, but there's a lack of common understanding and standards in its application.
- A team used the GRADE approach to assess evidence quality and made 30 recommendations for various venous diseases, focusing on both strong and moderate evidence.
- Among the recommendations, there were 7 strong recommendations and 17 backed by high-quality evidence, underscoring the necessity for more research in compression therapy.
Purpose: This retrospective study aims to evaluate the safety, practicality, and efficacy of the independent retrograde popliteal approach for recanalization superficial femoral artery (SFA) occlusions when the bilateral common femoral artery approach is unavailable, such as after endovascular aneurysm repair or common iliac artery stenting.
Methods: This treatment was considered for patients with contralateral iliac artery occlusion, severe iliac tortuosity, or those who had previously undergone endovascular aneurysm repair or common iliac stenting. Patients with SFA lesions extending into the P1-P2 segment of the popliteal artery or with calcification in the P3 segment were excluded.
Principles of Optimal Antithrombotic Therapy for Iliac VEnous Stenting (POATIVES): A national expert-based Delphi consensus study.
J Vasc Surg Venous Lymphat Disord
March 2024
Objective: Management of antithrombotic therapy in patients undergoing venous stents has not yet reached consensus, and there are not any recommendations from published guidelines. We undertook a Delphi consensus from Chinese experts to develop recommendations regarding the preferred antithrombotic therapy in patients following venous stenting.
Methods: The phase 1 questionnaire was comprised of three clinical scenarios of venous stenting for non-thrombotic iliac vein lesions (NIVL), acute deep vein thrombosis (DVT), and post-thrombotic syndrome (PTS) and was sent to venous practitioners across China.
Objective: Autogenous arteriovenous fistula (AVF) is recommended as the first choice for hemodialysis vascular access. A small-caliber vein is one of the independent risk factors for AVF maturation and patency. However, the specific threshold is still unclear, making it difficult to accurately determine whether these vessels are suitable for AVF creation.

- Recent studies suggest that paclitaxel treatments may increase mortality risk in patients with peripheral artery diseases (PAD), prompting a comparison between drug-eluting stents (DES) and drug-coated balloons (DCB).
- A systematic review of existing studies from 2000 to 2020 included 7 studies involving over 13,000 patients and used a random-effect model to analyze 12-month all-cause mortality rates.
- The findings indicated no significant differences in 12-month mortality, primary patency, or freedom from target lesion revascularization between patients treated with DES and those treated with DCB.
Objective: Iliac branch devices (IBDs) have been used in the treatment of aortoiliac and isolated iliac artery aneurysms. The aim of this systematic review and meta-analysis was to investigate the clinical effectiveness and safety of IBDs.
Methods: A systematic review of the literature was conducted by identifying studies in the Medline, EMBASE, and Cochrane databases regarding the outcomes of IBDs in aortoiliac or isolated iliac artery aneurysms between May 2006 and December 2020.

Article Synopsis
- The study aimed to evaluate the effectiveness of prophylactic cerebrospinal fluid drainage (CSFD) in preventing spinal cord ischemia (SCI) after thoracic endovascular aortic repair (TEVAR) for conditions like aortic dissection (AD) and thoracic aortic aneurysms (TAA).
- A systematic review and meta-analysis of 34 studies involving 3561 patients were conducted, comparing SCI rates between those who received CSFD and those who did not, with a focus on different types of aortic pathologies.
- The results showed that while CSFD reduced SCI rates for AD patients compared to those with aneurysms, there was no significant difference in SCI rates between patients using CSFD and those not
Objective: The comparisons between thoracic endovascular aortic repair for ruptured thoracic aorta (TEVAR) and open surgery (OS) have not been well documented, although both procedures have been widely utilized. We performed a systematic review and meta-analysis to investigate the effectiveness and safety between TEVAR and OS in the repair of ruptured descending thoracic aorta.
Methods: PubMed, Embase, and Cochrane Library databases were searched to find relevant studies to assess TEVAR and OS outcomes.
Background: There is an urgent need for accurate, rapid, inexpensive biomarkers that can differentiate coronavirus disease 2019 (COVID-19) from bacterial pneumonia. We assess the role of the ferritin-to-procalcitonin (F/P) ratio to classify pneumonia cases into those due to COVID-19 vs those due to bacterial pathogens.
Methods: This multicenter case-control study compared patients with COVID-19 with those with bacterial pneumonia, admitted between March 1 and May 31, 2020.
Chronic internal carotid artery occlusion (CICAO) significantly increases the risk of recurrent stroke. Given unfavorable outcomes, revascularization procedures are not generally recommended for CICAO. In the last several years, loads of studies reported successful surgical revascularization for CICAO with promising success rate and favorable short-term outcomes.
