Filter by:This is a Belgian prospective multicentre registry on the performance of the Smart stent in the superficial femoral artery according to the new tasc II-classification.
We seek to determine if the use of the SafeSeal(TM) topical hemostasis patch is associated with reductions in time to hemostasis and time to ambulation compared to standard manual compression after arterial sheath removal following percutaneous coronary and peripheral intervention. We further seek to assess the safety of the SafeSeal patch compared to manual compression.
The purpose of this first-in-man study is to evaluate the safety and performance of the Dynalink®-E everolimus eluting peripheral stent system for the treatment of patients with atherosclerotic de novo or restenotic native superficial femoral and proximal popliteal lesions. Abbott Vascular is ceasing data analysis of the STRIDES Clinical Trial after 2 years. The decision to discontinue the study is not related to any safety concern. The rationale for this proposal is based on the following considerations: The performance of DYNALINK-E from STRIDES shows no device- or procedure-related deaths and no stent fractures, and the rate of additional revascularizations has been stable since approximately 14 months after the procedure. Evaluations of the bare metal nitinol DYNALINK and ABSOLUTE stents in the clinical literature show low rates of death, reintervention and stent fracture, which are consistent with STRIDES and demonstrate the safety of the nitinol stent platform of the DYNALINK-E. Long-term animal studies show no concerns with the drug or polymer coating of DYNALINK-E - everolimus tissue concentration drops below the quantifiable limit by approximately 17 months after implant, and vascular response to the coating is normal with widely patent lumens and struts incorporated into vessel tissue. The safety and performance of the DYNALINK-E has been substantiated by its clinical and pre-clinical data, and by the clinical data of similar products. Given the demonstrated mechanical integrity of the stent along with the evidence of a healthy long-term vascular response, there is a reasonable expectation of continued low event rates.
The purpose of this study is to investigate the performance of paclitaxel-coated balloon expandable stainless steel coronary stent for the treatment of infrapopliteal stenoses and occlusions in patients with critical limb ischemia compared to percutaneous transluminal balloon angioplasty (PTA).
Diabetes is a very common illness. Approximately 4% of British Columbians have diabetes. However, at least 20% of people admitted to acute care hospitals have diabetes. People with diabetes are at a higher risk for developing complications after surgery including infection and prolonged hospital stay, especially if blood sugars are high. The researchers are testing a Diabetes Action Team to see if their involvement in patient care after surgery improves blood glucose control, duration of stay in hospital, and infection rates.
Physicians tend to always use the lowest dose of statins to initiate therapy even in subjects who require large reductions in cholesterol. The study evaluates if selecting the starting dose based on baseline and target LDL-C cholesterol would provide better results (ie proportion of subjects resching target)

To evaluate a new vascular sealant compared to control for the control of suture line bleeding after vascular reconstructive surgery.
The purpose of this study to compare balloon angioplasty (PTA) vs. cutting balloon angioplasty (CB-PTA) in terms of patency and postintervention inflammation in peripheral artery disease.
Critical limb ischemia is a condition where the blood circulation in the limbs, in most cases the legs, is decreased so that pain and non healing wounds ensue. Mostly, this is a sequel of arteriosclerosis and/or diabetes. If surgical and other methods for the improvement of blood supply for the leg have failed or are not possible, most of these patients will proceed to amputation of the leg. Bone marrow contains cells which can induce and augment the growth of new, small arteries called collateral arteries. It has been shown in animals and in some case series that the transplantation of a concentrate of the patient's own bone marrow with stem cells into the ischemic limb can improve the blood circulation via the induction of collateral growth. However, it is not known if this bone-marrow stem cell induced collateral growth is sufficient to avoid otherwise necessary amputations. Therefore, we conduct a study to compare the efficiency of concentrated bone marrow cells injected into the critically ischemic limb compared to a placebo procedure where only saline is injected. We think that the transplantation of autologous bone marrow will reduce the number of necessary leg amputations, reduce pain and induce wound healing. In this investigation, patients with limb threatening ischemia are randomly allocated either to the bone marrow group or to the placebo group. Patients in the bone marrow group will have their bone marrow harvested under sedation, and the bone marrow cells are concentrated. The cell concentrate will then be injected directly into the muscle of the diseased leg. Patients in the placebo group will undergo sedation as well but no bone marrow harvest is done, and saline is injected into the ischemic leg. The procedure will require about 1.5-2 hours, and the subjects will be admitted to a participating vascular Centre. Monthly examinations up to three months after the bone-marrow or placebo procedure are done. After the follow-up of three months, the rate of death and amputations and the wound healing process are compared between groups. Adverse and serious adverse events will be recorded during this time period. Diagnostic studies will be obtained to measure blood flow in the treated leg during the follow up period and include skin oxygen measurements, pressure recordings in the leg and arteriography. Also, quality of life, pain and wound healing will be assessed. After completion of the three months study participation, subjects who have been treated with placebo will be able to receive open-label bone marrow transplantation therapy.
