Short- and Mid-Term Outcomes of Bovine Pericardial Patch vs. Saphenous Vein Patch in Femoral Endarterectomy
Takashi Harada, Daisuke Futagami, Yuki Echie, Saeki Watanabe, Hironobu Morimoto, Keijiro Katayama, Shogo Mukai, Masahito Taniguchi
Objectives: Femoral endarterectomy often requires patch angioplasty, and saphenous vein patch (SVP) was the standard. However, bovine pericardial patch (BPP) provides potential advantages, including no requirement for vein harvest, use of the access site for concomitant endovascular procedures, and favorable handling characteristics. We compared the short- and mid-term outcomes of BPP and SVP in femoral endarterectomy.
Methods: This retrospective, single-center study included 42 patients (49 limbs) who underwent elective femoral endarterectomy with patch closure between September 2016 and January 2025. The patients were grouped by patch type as follows: 28 limbs with BPP and 21 limbs with SVP. Primary endpoints included patency and freedom from target lesion revascularization at the endarterectomy site. Secondary endpoints included perioperative complications, limb salvage, and intraoperative arterial clamp time.
Results: No patch-site restenosis or re-intervention occurred in either group. There were no patch infections, and the perioperative complications were similar. Limb salvage at 40 months was 87.5% with BPP vs. 95.0% with SVP (p = 0.42). Intraoperative arterial clamp time was significantly shorter in the BPP group (55.0 vs. 69.5 min, p = 0.01).
Conclusions: BPP represents a safe and valuable alternative option for femoral endarterectomy.

Objectives: The purpose of this study was to evaluate the results of endovascular therapy (EVT) with common femoral artery (CFA) endarterectomy site access for lower extremity artery disease (LEAD). Methods: Records were reviewed retrospectively for patients who underwent EVT with CFA endarterectomy site access from 2014 to 2023 at 7 hospitals. Results: A total of 74 EVT procedures with CFA endarterectomy site access were performed in 65 patients with LEAD. The median [interquartile range] interval between CFA endarterectomy and the first EVT access was 435 [237–1153] days. Technical success of EVT was achieved in 72 procedures (97%). Technical success of the puncture was achieved in all 74 procedures (100%). The median [interquartile range] puncture time and hemostasis time were 4 [2–6] and 13 [10–20] min, respectively. Two cases (3%) had access site hematoma, which was cured with conservative treatment. Conclusions: The CFA after endarterectomy may be a safe and suitable access site for EVT.

Extended Endarterectomy Across the Inguinal Ligament Using Inguinal-Lifting in the Surgery for Critical Limb Ischemia
Anna Tsuji, Shun-Ichiro Sakamoto, Motohiro Maeda, Tomohiro Murata, Atsushi Hiromoto, Kenji Suzuki, Yoshiyuki Watanabe, Yosuke Ishii
This case report presents a case of lower extremity peripheral arterial disease (PAD) with severe calcified lesions extending from the external iliac artery to the bifurcation of the superficial femoral artery, involving the groin region. Owing to the complexity and risk of complications, such as infections and delayed wound healing, revascularization was performed with extensive endarterectomy. The inguinal-lifting technique (ILT) was used to provide safe surgical access and minimize complications. The procedure resulted in successful revascularization with no major wound-related issues. The ILT proved to be an effective approach for safe, extensive endarterectomy in complex PAD cases.

Machine Learning and Abdominal Aortic Aneurysm: A New Paradigm in Prediction and Prognosis after Endovascular Aneurysm Repair
Toshiya Nishibe, Tsuyoshi Iwasa, Shoji Fukuda, Tomohiro Nakajima, Shinichiro Shimura, Masayasu Nishibe, Alan Dardik
Artificial intelligence (AI) and machine learning (ML) are transforming vascular surgery by enabling precise risk stratification, individualized treatment planning, and improved prognostic prediction. In abdominal aortic aneurysm (AAA) management, ML algorithms integrate complex clinical and imaging data to estimate survival, guide procedural decisions, and identify key factors influencing aneurysm remodeling. These models outperform traditional statistical approaches by capturing nonlinear interactions among variables such as nutritional status, immune function, and anatomical features. Despite these advances, challenges remain. Many studies rely on single-center datasets, raising concerns about overfitting and limited generalizability. The use of black-box models can hinder clinical trust due to limited interpretability. However, recent developments in multicenter data collection and explainable AI techniques are improving model robustness and transparency. As these tools continue to evolve, ML is poised to contribute meaningfully to precision vascular care. By supporting more individualized and data-informed decision-making, ML has the potential to enhance long-term outcomes and guide the future of AAA management after endovascular aneurysm repair.

Innominate Artery Transection via Combined Suprasternal and Intercostal Approach Prevents Tracheoinnominate Artery Fistula
Masahide Shichijo, Hiroyuki Morokuma, Nagi Hayashi, Takashi Teishikata, Masafumi Hiratsuka, Keiji Kamohara
Tracheoinnominate artery fistula is a rare but potentially fatal complication of tracheostomy. We report the case of a 22-year-old male at high risk for tracheoinnominate artery fistula due to severe thoracic deformity. To mitigate the risk, a prophylactic transection of the innominate artery was successfully performed using a combined suprasternal and intercostal approach, thereby avoiding limb perfusion. The patient was discharged without complications. This case highlights the effectiveness of the combined approach for safe innominate artery transection in anatomically challenging cases.

Akiyoshi Yamamoto, Shinichiro Shimura, Kenji Kuwaki, Hidekazu Furuya, Sohsyu Kotani, Kimiaki Okada, Keisuke Ozawa, Goro Kishinami, Shigeyuki Ozaki, Yasunori Cho
Objectives: The objective of this study was to compare the adhesive strength and flexibility of 3 surgical sealants—synthetic (Hydrofit; Sanyo Chemical Industries, Kyoto, Japan), albumin-based (BioGlue; Artivion, Kennesaw, GA, USA), and fibrin-based (Beriplast; CSL Behring, Tokyo, Japan)—which are commonly used in cardiovascular surgery but unexplored under identical experimental conditions.
Methods: Adhesive strength was evaluated using a tensile adhesion test on collagen, polyester, and polytetrafluoroethylene substrates. Flexibility was assessed by measuring the maximum stress and elongation at failure in Hydrofit and BioGlue film samples. Beriplast was excluded as it failed to form films.
Results: Hydrofit and BioGlue showed similar collagen–collagen adhesion strengths (p = 0.11), while Beriplast was significantly weaker (p <0.01). Hydrofit outperformed both BioGlue and Beriplast (p <0.01) in collagen–polyester and collagen–expanded polytetrafluoroethylene (ePTFE) adhesions. Hydrofit also demonstrated a significantly higher elongation rate, strength, and maximum stress before rupture than BioGlue.
Conclusions: These surgical sealants possess distinct adhesive and mechanical characteristics. Hydrofit showed stable adhesion across various substrates, with notable flexibility. BioGlue displayed adequate adhesion on collagen surfaces but had restricted flexibility. Beriplast demonstrated reduced adhesion. Although only adhesive strength and flexibility were evaluated, such properties may offer valuable insights into sealant traits contextually. These potentially aid in the selection of appropriate sealants for cardiovascular procedures that require both durable adhesion and tissue compliance. Further in vivo validation is warranted.

Supplement of Clinical Practice Guidelines for Endovenous Thermal Ablation for Varicose Veins 2019: Laser Ablation of Varicose Tributaries
Masayuki Hirokawa, Junichi Utoh, Satoru Sugiyama, Osamu Suzuki, Takashi Yamamoto, Tomohiro Ogawa, Makoto Mo, on behalf of the Guideline Committee, Japanese Society of Phlebology
In the treatment of saphenous varicose veins with endovenous laser ablation, simultaneous treatment of varicose tributaries using stab avulsion or sclerotherapy is commonly performed. To address the limitations of these conventional treatments, laser ablation for varicose tributaries has recently gained widespread acceptance. This guideline, developed by the Japanese Society of Phlebology, outlines appropriate treatment protocols for laser ablation of varicose tributaries. Indications include primary varicose veins requiring concurrent treatment of the saphenous trunk and varicose tributaries. The procedure utilizes slim radial fibers, with puncture and ablation performed using either short- or long-axis approaches. Although rare, adverse events such as skin burns, nerve injury, and fiber breakage have been reported. A learning curve is necessary to ensure the safe execution of the procedure. Further clinical studies are essential to enhance the safety and efficacy of laser ablation for varicose tributaries. (This is a secondary publication from Jpn J Phlebol 2025; 36: 51–58.)

Update on Cardiovascular Echo in Aortic Aneurysm and Dissection
Kazuhiro Nishigami
The majority of aortic aneurysms comorbid with atherosclerosis can be asymptomatic and are discovered incidentally on routine physical examination or on imaging studies for other indications. Transthoracic echocardiography is a basic modality to assess patients with coronary artery disease and can be used for the screening of aortic aneurysm. Acute aortic dissection is a highly lethal cardiovascular emergency and requires prompt recognition. Although cardiovascular echo has a suboptimal accuracy rate for detecting aortic dissection, it is noninvasive, readily available, and easy to use. Recently, the concept of point-of-care ultrasound (POCUS) refers to ...

Updates on Ultrasonography Imaging in Abdominal Aortic Aneurysm
Shinichi Iwakoshi, Toshiko Hirai, Kimihiko Kichikawa
Abdominal aortic aneurysms (AAAs) are life-threatening and are associated with >80% mortality when they rupture. Therefore, detecting these aneurysms before they rupture is critical. Ultrasonography is a non-invasive tool that is used for screening AAAs by measuring abdominal aorta diameter. A recent meta-analysis demonstrated the positive effects of ultrasonography. To date, aneurysm diameter is the most reliable predictor for aneurysm rupture and is used as a criterion for surgical intervention. However, some AAAs rupture at small diameters. Therefore, a better predictor for AAA rupture that is independent of aneurysm diameter is needed. Recently, an aortic wall strain examined using ultrasonography has been reported to have a potential in predicting AAA rupture....

Updates on Computed Tomography Imaging in Aortic Aneurysms and Dissection
Ryoichi Tanaka, Kunihiro Yoshioka, Akihiko Abiko
Computed tomography (CT) is a primary imaging modality for the diagnosis of aortic diseases, because of its minimal invasiveness and agility. Prompt and accurate diagnosis is crucial especially for acute aortic diseases, and the guidelines for acute aortic dissection recommend the use of CT for initial diagnosis. For the follow-up observation of longstanding aortic diseases, the strategy of imaging management by CT must be different from that for emergency and acute phases. In this review, we document the differences in characteristics and clinical course between aortic aneurysm and aortic dissection and explain the use of recent CT techniques in diagnosing short- and longstanding aortic diseases.
