Background Deep venous thrombosis after any surgical operations is considered a preventable complication. Lower extremity bypass surgery is a commonly performed operation to improve blood flow to lower extremities in patients with severe peripheral arterial disease. Despite advances in endovascular surgery, lower extremity arterial bypass remains the gold standard treatment for severe, symptomatic peripheral arterial disease. The purpose of this study is to identify the clinical risk factors associated with development of deep venous thrombosis after lower extremity bypass surgery...

Introduction.Listeria monocytogenes is a rare etiology of infectious endocarditis with only 30 cases of prosthetic valve and about twice as many native valve infections described in the literature. We describe an unusual presentation of an endovascular embolic phenomenon with associated lower extremity mycotic aneurysm due to Listeria monocytogenes prosthetic aortic valve and aortic endograft infection. Case presentation. This is a case of an elderly gentleman with prior history of bioprosthetic aortic valve placement and aortic arch repair who was admitted with several weeks of constitutional symptoms and left lower leg pain...

OBJECTIVE: Readmission rates are expected to have an increasing effect on both the hospital bottom line and physician reimbursements. Safety net hospitals may be most vulnerable. We examined readmissions at 30 days, 90 days, and 1 year in a large safety net hospital to determine the magnitude and effect of short and long-term readmission rates after lower extremity infrainguinal bypass in this setting. METHODS: All nonemergent extremity infrainguinal bypass performed at a large safety net hospital between 2008 and 2016 were identified...

OBJECTIVE: Technical progress in angioplasty expanded its application to very distal arterial lesions of the lower extremity. In cases of unsuccessful angioplasty tibiodistal bypass surgery may be required for limb salvage. We investigated the long-term outcome of this technique in patients with critical limb ischemia. The purpose of this study was to evaluate whether tibiodistal bypasses done after unsuccessful tibial angioplasty had inferior patency, limb salvage, or survival rates compared with primary tibiodistal bypasses...

OBJECTIVE: The effect of diabetes type and insulin dependence on short- and long-term outcomes after lower extremity revascularization for chronic limb-threatening ischemia (CLTI) warrants additional study and more targeted focus. We sought to address this paucity of information by evaluating outcomes in insulin-dependent and noninsulin-dependent patients after any first-time revascularization. METHODS: We reviewed all limbs undergoing first-time infrainguinal bypass grafting (BPG) or percutaneous transluminal angioplasty with or without stenting (PTA/S) for CLTI at our institution from 2005 to 2014...

BACKGROUND: The posterior cerebral artery (PCA) is involved in approximately 30% of moyamoya disease (MMD) cases. However, there have been insufficient reports describing revascularization techniques in the posterior portion of the brain, particularly of direct anastomosis. OBJECTIVE: To perform a technical assessment in patients with MMD who underwent either occipital artery (OA)-PCA bypass or OA-middle cerebral artery (MCA) bypass. METHODS: A total of 428 revascularization procedures in 368 patients were retrospectively assessed by reviewing clinical charts and radiological data...

Chronic expanding hematoma (CEH) after coronary artery bypass grafting (CABG) is extremely rare. We reported a case of successful surgical repair of CEH through lower partial sternotomy approach. The patient was a 73-year-old man who underwent CABG. Fifteen years after the operation, he was admitted to referral hospital because of dyspnea on exertion. Echocardiography and computed tomography revealed a giant intrapericardial mass, which was pressing on the inferior wall of the ventricle. To avoid injury of the aorta and the patent bypass graft in the reentry of the chest, we selected lower partial sternotomy approach...

INTRODUCTION/OBJECTIVES: Endovascular repair of a proximal anastomotic pseudoaneurysm of an end-to-side aortobifemoral bypass (ABF) can lead to pelvic ischemia. We present a novel application of branched aortic endograft to repair such pseudoaneurysm while preserving flow into the ABF and native aortoiliac system. METHODS: A 71 year old male with history of aortoiliac occlusive disease resulting in lifestyle limiting claudication was treated with an aortobifemoral bypass in 1999...

BACKGROUND: Among patients undergoing non-cardiac surgery, major vascular surgery is associated with a high risk of perioperative myocardial infarction (MI). Currently there are no perioperative MI risk calculators accounting for intraoperative and postoperative risk factors in vascular surgery patients. We aimed to investigate specific risk factors for perioperative MI after major open vascular surgery to determine which patients are at highest risk of MI, and the association of perioperative MI with perioperative transfusion...

OBJECTIVE: Venous thromboembolism (VTE) is reported to occur in up to 33% of patients undergoing major vascular surgery. Despite this high incidence, patients inconsistently receive timely VTE chemoprophylaxis. The true incidence of VTE among patients receiving delayed VTE chemoprophylaxis is unknown. We sought to identify the association of VTE chemoprophylaxis timing on VTE risk, postoperative transfusion rates, and 30-day mortality and morbidity in patients undergoing major open vascular surgery...

Objective Postoperative pain following lower extremity revascularization procedures is traditionally controlled with narcotic administration. However, this may not adequately control the pain and puts the patient at risk for complications from opiate use. Here we report an alternative strategy for pain management using a continuous catheter-infused local anesthetic into the operative limb. Design Retrospective case-control study. Methods Patients undergoing lower extremity revascularization procedures using continuous catheter-infused local anesthetic were compared to similar patients undergoing similar procedures during the same time period who did not receive continuous catheter-infused local anesthetic...

OBJECTIVE: Lower extremity bypass (LEB) operations have high rates of surgical site infections (SSI). Phenylephrine is a commonly used vasoconstrictor which may reduce skin blood flow and increase the likelihood of SSI in these patients. We studied the potential effect of phenylephrine infusion during LEB surgery on SSI. METHODS: LEB cases and their demographic data were identified through the Vascular Quality Initiative registry. SSI in this population was identified using the hospital epidemiology surveillance database...

Objectives The use of postoperative anticoagulation is not uncommon for patients undergoing lower extremity arterial procedures as adjunctive therapy. Longer postoperative length of stay is necessary to achieve adequate therapeutic international normalized ratio with traditional protocols that call for the use of unfractionated heparin and warfarin therapy. We hypothesized the direct oral anticoagulants are an attractive alternative to provide adequate anticoagulation in patients who undergo lower extremity arterial procedures...

Multidrug resistance (MDR) is a huge obstacle in cancer chemotherapeutics. Overcoming MDR is a great challenge for anticancer drug discovery. Here, DNA binding and cytotoxicity of Schiff base L1 and L2 were explored to assess their efficiency in fighting cancer and overcoming the MDR. L1 and L2 could treat extremely chemoresistant MCF-7/ADR cell as drug-sensitive cell, with drug resistance index (DRI) <2.13, showing high potential in overcoming the MDR. The apoptotic ratio induced by L1 and L2 was low for both MCF-7 and MCF-7/ADR cells...
