Objectives: Since 2018, we have routinely placed an Amplatzer vascular plug (AVP) in the proximal left subclavian artery (LSCA) to prevent embolic events during thoracic endovascular aortic repair with arch vessel debranching (d-TEVAR). Type II endoleaks of LSCA origin were observed in two patients (20%), and the coil-in-plug (CIP) method, i.e., microcatheter insertion through the plug and addition of coil embolization, which has been used since August 2019, was performed. This study aims to evaluate the effectiveness of the CIP method for LSCA embolization...

Objectives: It is unclear whether patients with acute pulmonary thromboembolism (PE) with and without residual deep vein thrombosis (DVT) have different prognoses, and there is debate over whether inferior vena cava filters (IVCFs) should be used in conjunction with oral anticoagulants in patients with venous thromboembolism (VTE). Materials and Methods: The J'xactly involved 1,016 patients and was a multicenter, prospective, observational research. In this subanalysis, 419 patients with PE with or without residual DVT who received rivaroxaban with or without IVCFs between February 2016 and April 2018 in Japan were examined...

We herein present a case involving an 86-year-old man with abdominal aortic aneurysm complicated by symptomatic disseminated intravascular coagulation (DIC). The patient received preoperative treatment for DIC using recombinant human soluble thrombomodulin (rTM) followed by open surgical repair of the aneurysm. The patient's coagulopathy cleared quickly after the start of rTM, and the intraoperative and postoperative course went smoothly. The patient was followed without anticoagulant medication, and there was no recurrence of DIC during 14 months of follow-up...

A 53-year-old man suddenly developed chest and back pain while driving, resulting in an accident. Computed tomography revealed acute type A aortic dissection with malperfusion of the left lower extremity, retroperitoneal extravasation, hematoma in the anterior mediastinum, and ascites in the rectovesical pouch. Exploratory laparotomy before aortic repair revealed intestinal perforation and retroperitoneal bleeding, which were repaired, and an ascending aortic replacement was performed. Visceral trauma with active bleeding should be treated with priority, even if the need for systemic heparinization accompanies acute type A aortic dissection during surgery for aortic dissection...

Objective : Due to the potential of thrombus blockage and aneurysm rupture, saphenous veins with varicose veins are not advised for use as bypass grafts. However, if no other autologous vein is accessible for use as a conduit in lower-limb bypass; varicose vein transplants may be employed. Few reports have studied the clinical results of lower-limb bypass using varicose vein grafts. We therefore investigated whether or not acceptable patency rates of varicose vein graft for lower-limb bypass could be achieved...

After previous earthquakes, high prevalence of cardiovascular diseases including venous thromboembolism (VTE) has been reported. We performed venous screening at the site of Hokkaido East Iburi Earthquake which happened at 6th September 2018. VTE screening using ultrasound sonography was performed for total 7 days at Atsuma town, Mukawa town and Abira town (total 9 shelters). Deep vein thrombosis (DVT) was found in 19 of 195 evacuees (9.7%), including 8 fresh thrombus cases (4.1%). On multivariable analysis of evacuees and shelter environment factors, systolic blood pressure, use of cardboard bed and toilet environment were significant predictor of DVT...

Objective: This study aimed to clarify the features and causes of dependent edema (DE) in the legs of patients in geriatrics. Patients and Methods: We retrospectively reviewed 224 patients with DE, aged ≥65 years, who visited our clinic from April 2009-March 2022. DE was defined as bilateral leg edema in patients without known systemic edemagenic conditions, venous insufficiency confirmed by duplex venous scanning, or a cancer treatment history in the pelvic/inguinal lesions. Results: The median patient age was 77 years (range: 65-94 years), where 74% were female...

Objectives: In this study, we aim to assess the efficacy of revision using distal inflow (RUDI) in patients with symptomatic dialysis access-associated steal syndrome (DASS). Materials and Methods: All consecutive patients who were diagnosed with grade 3 or 4 DASS and have undergone RUDI in 4 years were included in this study. Results: In total, 35 patients were included in this study; participants had a mean age of 47.5±7.52 years and 54% (n=19) were males. As per our findings, significant improvement was noted in terms of paresthesia (81...

A 65-year-old Japanese man without medical history presented with sudden onset lower abdominal pain to our emergency department. Contrast-enhanced computed tomography (CT) revealed dissections of the inferior mesenteric artery and left renal artery with false lumen thrombosis without aortic dissection. He was immediately hospitalized, and conservative treatment was administered. However, on the third-day post-onset, the patient reported severe upper abdominal pain and contrast-enhanced CT showed a new superior mesenteric artery dissection...

As compared with pressure injuries, the mechanism the development of medical device related pressure ulcers (MDRPU) is not revealed enough. According to studies on severity and frequent site of occurrence, MDRPUs are surmised to occur the surface of the skin. In this study, we assess theoretical and experimental analysis by two-dimensional mechanical model for elastic stockings (ES) wear the lower limbs with or without dug into the skin by the wrinkles and curling up of ES. The Finite Element Method (FEM) was used to calculate the stress on the skin and subcutaneous tissue, because of elucidating the mechanism of MDRPU...

In this study, we present a case of 59-year-old man with a posterior tibial artery (PTA) aneurysm. Mostly, PTA aneurysm is caused by trauma, infection, and iatrogenic injury. The patient had a history of ankle trauma that occurred 2 years ago. Computed tomography and ultrasonography showed a 7×14 mm PTA aneurysm. The aneurysm was resected and primary end-to-end anastomosis was performed. So far, there are only few reported cases of PTA aneurysm. Herein, we describe the surgical strategy and provide detailed intraoperative images...

Objectives: To estimate the effectiveness of balloon aortic valvuloplasty (BAV) for severe aortic stenosis (SAS) in patients scheduled for open surgery for chronic limb-threatening ischemia. Materials and Methods: Clinical data of patients from 2012 to 2018 were retrieved and summarized. The early outcomes and survival after BAV and open bypass were retrospectively investigated. Results: BAV was performed on seven dialysis patients. One patient died of mesenteric infarction 3 days after BAV; however, six patients were able to undergo open bypass at an average of 10 days (7-19 days) after BAV...

A 40-year-old female, who underwent transcatheter arterial embolization due to acute bleeding from an iliolumbar artery, was subsequently genetically diagnosed with vascular Ehlers-Danlos syndrome. She experienced chronic anemia for many years due to the easy bruising of her whole body. The bruising improved with oral administration of celiprolol hydrochloride. There were no cardiac or vascular events during the 7 years following the transcatheter arterial embolization. Vascular Ehlers-Danlos syndrome requires specialized treatment that is scientifically proven to prevent a major vascular event...

Peripheral venous thromboembolism is a well-known complication of hormonal contraception, but reports on its association with visceral vein thrombosis is limited. We report the case of left renal vein thrombosis (RVT) associated with oral contraceptives (OCs) and concurrent smoking. The clinical presentation of this patient was acute left flank pain. Computed tomography revealed left RVT. The OC was discontinued, and we initiated anticoagulation with heparin and switched to edoxaban. Computed tomography 6 months later showed complete resolution of the thrombosis...

Objectives: This study aimed to investigate the clinical features of arterial thrombosis and venous thromboembolism (VTE) in coronavirus disease 2019 (COVID-19). Methods: The CLOT-COVID Study was a retrospective, multicenter cohort study that enrolled 2,894 consecutively hospitalized patients with COVID-19 among 16 centers in Japan from April 2021 to September 2021. We compared the clinical features of arterial thrombosis and VTE. Results: Thrombosis was observed in 55 patients (1.9%) during hospitalization...

Objective: The relationship between nutritional status and morbidity and death in a number of diseases and disorders has garnered considerable attension. In patients having endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAA), we assessed the prognostic value of nutritional markers of albumin (ALB), body mass index (BMI), and geriatric nutritional risk index (GNRI) for long-term mortality. Materials and Methods: Retrospective data analysis was done on patients who had undergone elective EVAR for AAA more than 5 years earlier...

Objectives: Concerns among susceptible individuals, especially those with vascular malformations, have been raised by reports of thromboembolism following the administration of the SARS-CoV-2 vaccination against coronavirus disease 2019 (COVID-19). This study's goal was to assess any negative side effects that patients with vascular malformations who received the SARS-CoV-2 vaccine reported after receiving it. Materials and Methods: Through the three patient groups for vascular malformations in Japan in November 2021, a questionnaire was distributed to patients with vascular malformations who were 12 years of age or older...

We report perioperative management and open surgery to treat a case of infrarenal abdominal aortic aneurysm with essential thrombocythemia (ET), a chronic myeloproliferative disorder associated with arterial or venous thrombosis, idiopathic bleeding, and heparin-resistant diathesis. Following careful preoperative management, including assessment of heparin resistance, open surgery was successfully performed to treat the aortic aneurysm of our patient. This report shows that optimal preparation for surgery is important to safely perform abdominal aortic aneurysm repair and prevent perioperative thrombosis and bleeding in patients with abdominal aortic aneurysm with ET...

We report a case of recurrent internal iliac artery aneurysm previously treated with a combination of stent graft placement and coil embolization in an 85 year-old male patient. The patient was scheduled for the direct puncture embolization of the superior gluteal artery. The patient was placed in a prone position under general anesthesia. An 18G-PTC needle was inserted into the superior gluteal artery under ultrasonographic guidance. A 2.2F microcatheter was inserted through an outer needle and advanced to the aneurysmal sac...
