Methods: This was a national registry based retrospective comparative study using data from the Japanese Registry of all Cardiac and Vascular Diseases Diagnostic Procedure Combination (JROAD-DPC) database, a nationwide claim based database from more than 600 hospitals. Patients admitted to certificated teaching hospitals with rDTAA and rAAA and treated by either ER or OR between 1 April 2012 and 31 March 2015 were identified.

Late-Onset Malignant Neoplasms and Their Prognostic Factors after Abdominal Aortic Aneurysm Repair.

Background: Little is known about late-onset primary malignant neoplasms after repair of abdominal aortic aneurysms (AAAs) despite malignancy being one of the primary causes of late death. We investigated the incidence and prognostic factors related to the occurrence of malignancy after AAA repair.

Methods: We performed a retrospective analysis of 589 patients who underwent AAA repair, including 264 endovascular AAA repairs and 325 open surgical repairs; 482 patients had no history of previous malignancy or concomitant malignancy, 72 had previous malignancy, and 35 had concomitant malignancy in remission at the time of AAA repair.

Cilostazol Improves Wound Healing in Patients Undergoing Open Bypass for Ischemic Tissue Loss: A Propensity Score Matching Analysis.

Background: Few reports have described the effects of medication on the wound healing of ischemic ulcers after revascularization. This study was conducted to investigate the effects of cilostazol on wound healing in patients who underwent infrainguinal bypass for ischemic tissue loss.

Methods: Two hundred sixty-three limbs undergoing de novo infrainguinal bypass for tissue loss from January 2004 to December 2015 were divided into 2 groups based on whether or not cilostazol was administered after surgery.

Aggressive Wound Care by a Multidisciplinary Team Improves Wound Healing after Infrainguinal Bypass in Patients with Critical Limb Ischemia.

Background: A long period is generally required for ischemic ulcer to heal after revascularization. The strategy of postoperative wound care can affect wound healing. This study was conducted to investigate the degree to which aggressive wound care (AWC) by a team of multidisciplinary specialists actually shortens the time to wound healing and increases the rate of wound healing in limbs undergoing surgical bypass for ischemic tissue loss in a real clinical setting.

BubR1 Insufficiency Results in Decreased Macrophage Proliferation and Attenuated Atherogenesis in Apolipoprotein E-Deficient Mice.

Background: Budding uninhibited by benzimidazole-related 1 (BubR1), a cell cycle-related protein, is an essential component of the spindle checkpoint that regulates cell division. BubR1 insufficiency causes early aging-associated vascular phenotypes. We generated low-BubR1-expressing mutant (BubR1) and apolipoprotein E-deficient (ApoE) mice (BubR1-ApoE mice) to investigate the effects of BubR1 on atherosclerosis.

Primary aortoduodenal fistula with a history of distal gastrectomy.

Case: A 69-year-old man was transferred to our hospital because of an aortoduodenal fistula with hematemesis and pre-shock vital signs. He had a history of alcoholism, malnutrition, and distal gastrectomy and Billroth I reconstruction. Endovascular aneurysm repair was successfully carried out; however, the presence of comorbidities affected further radical treatment.

Raison d'etre of Tibial Artery Bypass for Intermittent Claudication in the Era of Endovascular Therapy.

Background: There is currently no positive opinion regarding infrapopliteal revascularization for intermittent claudication (IC) in any guidelines. The aim of this study was to analyze the outcomes of infragenicular bypass and verify the adequacy of tibial artery bypass for IC.

Methods and results: Over a 21-year period, 58 below-knee popliteal artery (BKPOP) bypasses and 35 tibial artery bypasses were performed for IC caused by arteriosclerosis obliterans.

Long-Term Results of a Hybrid Revascularization Procedure for Peripheral Arterial Disease.

Objective: To evaluate the efficacy of hybrid procedure for peripheral arterial disease (PAD), we compared the cases treated using the hybrid procedure with those treated using open revascularization (bypass alone) in our facilities.

Materials And Methods: We retrospectively reviewed 204 patients who underwent revascularization for PAD between 2007 and 2013. We divided the patients into two groups based on the type of procedure.

BubR1 insufficiency inhibits neointimal hyperplasia through impaired vascular smooth muscle cell proliferation in mice.

Objective: BubR1, a cell cycle-related protein, is an essential component of the spindle checkpoint that regulates cell division. Mice with BubR1 expression reduced to 10% of the normal level display a phenotype characterized by progeria; however, the involvement of BubR1 in vascular diseases is still unknown. We generated mice in which BubR1 expression was reduced to 20% (BubR1(L/L) mice) of that in wild-type mice (BubR1(+/+)) to investigate the effects of BubR1 on arterial intimal hyperplasia.

Midterm outcomes of endovascular repair for abdominal aortic aneurysms with the on-label use compared with the off-label use of an endoprosthesis.

Purpose: Endovascular repair of an abdominal aortic aneurysm (EVAR) is sometimes not performed in accordance with the instructions for use (IFU) of the endoprosthesis ("off-label use"). We investigated whether the off-label use of the endograft affected the outcomes of EVAR.

Methods: Demographic, anatomical, intraoperative and follow-up data on 100 patients in whom the endograft was used on-label in EVAR were compared retrospectively with the corresponding data of 50 patients with off-label endograft use.

Evaluation of the paramalleolar bypass for critical limb ischemia patients on hemodialysis with diabetes mellitus and chronic renal failure.

Objective: To assess the influence of diabetes mellitus (DM) and end-stage renal failure on hemodialysis (HD) on the healing time of tissue lesions and blood flow to the foot following a paramalleolar bypass in patients with critical limb ischemia (CLI).

Methods: Consecutive patients with CLI and tissue loss (24 limbs) were followed up retrospectively after paramalleolar bypass, and the healing time of tissue lesions, graft patency, limb salvage and survival rates were analyzed. The blood flow to the foot was assessed by skin perfusion pressure (SPP) pre- and postoperatively.

Ex vivo generation of highly purified and activated natural killer cells from human peripheral blood.

Adoptive immunotherapy using natural killer (NK) cells has been a promising treatment for intractable malignancies; however, there remain a number of difficulties with respect to the shortage and limited anticancer potency of the effector cells. We here established a simple feeder-free method to generate purified (>90%) and highly activated NK cells from human peripheral blood-derived mononuclear cells (PBMCs). Among the several parameters, we found that CD3 depletion, high-dose interleukin (IL)-2, and use of a specific culture medium were sufficient to obtain highly purified, expanded (∼200-fold) and activated CD3(-)/CD56(+) NK cells from PBMCs, which we designated zenithal-NK (Z-NK) cells.

Endovascular aneurysm repair for an abdominal aortic aneurysm and a left ruptured common iliac artery aneurysm in a patient with hepatocellular carcinoma: report of a case.

A 68-year-old male presented with acute lower abdominal pain. Abdominal computed tomography (CT) showed a 4.

DVC1-0101 to treat peripheral arterial disease: a Phase I/IIa open-label dose-escalation clinical trial.

We here report the results of a Phase I/IIa open-label four dose-escalation clinical study assessing the safety, tolerability, and possible therapeutic efficacy of a single intramuscular administration of DVC1-0101, a new gene transfer vector based on a nontransmissible recombinant Sendai virus (rSeV) expressing the human fibroblast growth factor-2 (FGF-2) gene (rSeV/dF-hFGF2), in patients with peripheral arterial disease (PAD). Gene transfer was done in 12 limbs of 12 patients with rest pain, and three of them had ischemic ulcer(s). No cardiovascular or other serious adverse events (SAEs) caused by gene transfer were detected in the patients over a 6-month follow-up.

Clinico-pathological features and management of lung cancer patients with atherosclerotic vascular diseases.

Purpose: Increased numbers of patients with both lung cancer and atherosclerotic vascular disease (AVD) may be expected in the future. The aim of this study was to report the incidence of lung cancer in patients with AVD and to discuss patient characteristics and management.

Method: A total of 638 patients who underwent AVD treatment were investigated.

BioKnife, a uPA activity-dependent oncolytic Sendai virus, eliminates pleural spread of malignant mesothelioma via simultaneous stimulation of uPA expression.

Malignant pleural mesothelioma (MPM) is highly intractable and readily spreads throughout the surface of the pleural cavity, and these cells have been shown to express urokinase-type plasminogen activator receptor (uPAR). We here examined the potential of our new and powerful recombinant Sendai virus (rSeV), which shows uPAR-specific cell-to-cell fusion activity (rSeV/dMFct14 (uPA2), named "BioKnife"), for tumor cell killing in two independent orthotopic xenograft models of human. Multicycle treatment using BioKnife resulted in the efficient rescue of these models, in association with tumor-specific fusion and apoptosis.

Clinical Results of Endovascular Abdominal Aortic Aneurysm Repair in Patients with Renal Insufficiency without Hemodialysis.

Objective: Chronic renal insufficiency may be a relative contraindication to endovascular aneurysm repair (EVAR) for the use of contrast enhanced mediums. It is thought that more contrast enhanced media are needed in patients who are not anatomically suitable for EVAR, because of procedural difficulties. We reviewed a 2 year EVAR experience at our institution to determine whether the procedure and use of contrast enhanced mediums has any deleterious effect on renal function in patients with pre-existing chronic renal insufficiency.

Mid-term clinical outcome of critical limb ischemia after infrapopliteal bypass surgery.

Objective: Critical limb ischemia caused by peripheral arterial occlusive disease of the infrapopliteal segment is best managed by bypass surgery with an autogenous vein conduit. Yet there remains confusing heterogeneity in the strategy, utilization, techniques, and outcomes in current practice. We reviewed our 7-year experience of infrapopliteal bypass surgery to analyze early and mid-term clinical outcomes.

Reduced proliferation of aged human vascular smooth muscle cells--role of oxygen-derived free radicals and BubR1 expression.

Background: Aging is a risk factor for atherosclerosis. Recent studies suggest cell cycle events as well as reactive oxygen species (ROS) contribute to vascular cell dysfunction associated with aging. Mice expressing low levels of the spindle assembly checkpoint protein BubR1 develop aging-associated vascular changes at a young age, including decreased smooth muscle cells and increased reactive oxygen species (ROS) production.

Fibromuscular dysplasia of the lower extremities.

Fibromuscular dysplasia (FMD) is a nonatherosclerotic, non-inflammatory vascular disease that mainly affects the renal and internal carotid arteries. Involvement of other sites, including arteries of the extremities, is uncommon, and only a few histologically confirmed cases have been reported. FMD of the arteries of the extremities can result in ischemia requiring surgical or endovascular reconstruction.
