Feasible Evaluation of PQ Bypass Results with Duplex Ultrasound
2019
Abstract Patients with peripheral arterial disease (PAD) have substantially impaired health-related quality of life (HR-QoL). Chronic lower limb ischaemia due to the atherosclerotic occlusion of infra-inguinal arteries is one of the most important causes of invalidity among smokers over the age of fifty. Historically, these lesions were treated by open bypass surgery. Less invasive endovascular revascularisation methods are available to treat short lesions, while treatment of long lesions are lacking. Fully endovascular trans-venous femoro-popliteal bypass (PQ Bypass, Inc., Sunnyvale, CA, USA) to treat long femoral lesions has been developed recently. The objective of the study was to evalu…
Prediction of N0 Irradiated Rectal Cancer Comparing MRI Before and After Preoperative Chemoradiotherapy
2017
Background: The prediction of lymph node status using MRI has an impact on the management of rectal cancer, both before and after preoperative chemoradiotherapy. Objective: The purpose of this study was to maximize the negative predictive value and sensitivity of mesorectal lymph node imaging after chemoradiotherapy because postchemoradiation node-negative patients may be treated with rectum-sparing approaches. Design: This was a retrospective study. Settings: The study was conducted at a tertiary care hospital. Patients: Sixty-four patients with locally advanced rectal cancer who underwent preoperative chemoradiotherapy and MRI for staging and the assessment of response were evaluated. Mai…
Klinische Erfahrungen mit dem Kensey-Katheter-System - Komplikationen und Ergebnisse
1990
Fifteen procedures have been carried out in 14 patients using the Kensey rotation angioplasty system. Sixteen occlusions of the superficial femoral artery, with an average length of 10.2 cm (3 to 24 cm) and one artery with multiple stenoses were treated. The following results were obtained: creation of a lumen, with subsequent balloon dilatation in eight out of fifteen procedures; in two patients the vessels were occluded shortly after the procedure, due to complications (one obstructive plaque and one haematoma); five perforations, three dissections and one peripheral embolus. The total complication rate was 11 out of 15 cases, clinical improvement was obtained in six out of 15 cases.
Iliac-femoral stent-graft infection after hybrid procedure redo: Case report
2021
Introduction Stent-graft infection in peripheral arteries is rare and potentially dangerous. The use of hybrid procedures, in complicated patients previously treated, involves an increase of infective risk especially in no collaborative patients. Presentation of case We report a case of rare stent-graft infection in a patient treated for a Rutherford IV Multiple Peripheral Arterial Disease (MPAD) involving the right iliac-femoral axis with stenosis on deep femoral artery due to a previously stenting procedure for Superficial Femoral artery (SFA) stenosis. The first simultaneous hybrid intervention consisted of an endovascular iliac stent-graft placement and a surgical common femoral patch a…
Can chemotherapy concomitantly delivered with radiotherapy improve survival of patients with resectable rectal cancer? A meta-analysis of literature …
2010
Summary Background There is clear evidence from two systematic reviews that radiotherapy (RT) reduces the risk of local recurrence in patients with resectable rectal cancer, though the data on survival are still equivocal. Objective To assess the effects of chemotherapy combined concomitantly with radiotherapy (CRT) on the increase of overall survival, and on the prevention of local recurrence and distant metastases. Data sources Computerized bibliographic searches of MEDLINE and CANCERLIT (1970–2008) were supplemented with hand searches of reference lists. Study selection Studies were included if they were randomized controlled trials (RCTs) comparing preoperative or postoperative CRT to p…
The impact of radiotherapy on survival in resectable gastric carcinoma: A meta-analysis of literature data.
2007
Summary Background The benefit of external radiotherapy for gastric carcinoma has been extensively studied, but data on survival are still equivocal. Objective To assess the effectiveness of surgery combined with preoperative radiotherapy or postoperative chemoradiotherapy in the reduction of all-cause mortality in patients with resectable gastric carcinoma. Methods Computerised bibliographic searches of MEDLINE and CANCERLIT (1970–2006) were supplemented with hand searches of reference lists. Study selection Studies were included if they were randomised controlled trials (RCTs) comparing mortality of surgery combined with preoperative radiotherapy or postoperative chemoradiotherapy to surg…
Renal artery denervation for treating resistant hypertension: Definition of the disease, patient selection and description of the procedure
2012
Arterial hypertension is responsible for a significant burden of cardiovascular morbidity and mortality, worldwide. Although several rational and integrated pharmacological strategies are available, the control of high blood pressure still remains largely unsatisfactory. Failure to achieve effective blood pressure control in treated hypertensive patients may have a substantial impact on individual global cardiovascular risk, since it significantly increases the risk of developing hypertension-related macrovascular and microvascular complications. Arterial hypertension is arbitrarily defined as 'resistant' or 'refractory' when the recommended blood pressure goals (clinic blood pressure below…
Duration of breastfeeding as a risk factor for vertebral fractures
2014
Abstract Purpose Among the risk factors for osteoporosis and fractures, gynecological history (fertile period, parity and breastfeeding) play an important part. Changes in calcium metabolism to enable an adequate mineral transfer to the milk have a prominent role in bone loss during breastfeeding. Data on the influence of breastfeeding in postmenopausal osteoporosis are inconsistent. The aim of the present study was to identify any association between duration of breastfeeding and vertebral fractures in postmenopausal women. Methods All patients underwent the following tests: bone mineral density measurements of the lumbar spine (L1–L4) and the total and femoral neck using dual-energy X-ray…
The acute myotoxic effects of bupivacaine and ropivacaine after continuous peripheral nerve blockades.
2003
Bupivacaine causes muscle damage. However, the myotoxic potency of ropivacaine is still unexplored. Therefore, we performed this study to compare the effects of bupivacaine and ropivacaine on skeletal muscle tissue in equipotent concentrations. Femoral nerve catheters were inserted into anesthetized minipigs, and 20 mL of either bupivacaine (5 mg/mL) or ropivacaine (7.5 mg/mL) was injected. Subsequently, bupivacaine (2.5 mg/mL) and ropivacaine (3.75 mg/mL) were continuously infused over 6 h. Control animals were treated with corresponding volumes of normal saline. Finally, muscle samples were dissected at injection sites. After processing and staining, histological patterns of muscle damage…
Antiproliferative Potential of African Medicinal Plants
2013
Increasingly, cancer is recognized as a critical public health problem in Africa. Medicinal plants constitute a good alternative treatment, considering the rich biodiversity of the continent. Scientific evidence of the antiproliferative activity of African medicinal plants is more and more common. The most prominent results reported include the cytotoxic effects of plants of the families Moraceae, Guttiferae, Fabaceae, as well as compounds of the groups of terpenoids and phenolics derived from African plants.
