Changing pattern of major lower limb amputations in Seinäjoki Central Hospital 1997-2000.

Background And Aims: There is rather limited recent information on major amputations in Finland. Our objective was to describe the incidence of major lower limb amputations in a defined central hospital, the demographic characteristics of the amputees, diagnosis and situations leading to amputation, level of amputations and survival of the amputees after one year.

Material And Methods: A retrospective study was undertaken on 156 patients with 169 lower limb major amputations from 1997 to 2000 at the Seinäjoki Central Hospital and Ahtäri District Hospital.

In vivo detection of intervertebral disk injury using a radiolabeled monoclonal antibody against keratan sulfate.

Unlabelled: In the intervertebral disk, proteoglycans form the major part of the extracellular matrix, surrounding chondrocytelike disk cells. Keratan sulfate is a major constituent of proteoglycans.

Methods: We have radioiodinated a monoclonal antibody raised against keratan sulfate.

Magnetic resonance imaging angiography in patency evaluation of bronchial artery revascularization grafts.

In this report we present our experience of non-invasive magnetic resonance imaging (MR) angiography and selective catheter angiography in assessing the patency of bronchial artery revascularization grafts after an en bloc double-lung and heart-lung transplantation. We studied 8 patients who had undergone pulmonary transplantation with direct bronchial artery revascularization. Catheter angiography was performed 10 days to 63 months postoperatively.

The effect of nitecapone on early graft function in experimental single lung transplantation.

Nitecapone is an antioxidant molecule which has been shown to protect the heart against ischemia-reperfusion injury. We investigated whether a similar effect could be detected on lung graft preservation in a porcine model of single lung transplantation. Donors received either nitecapone or placebo in a modified Euro-Collins pulmonary flush solution.

Laser Doppler flowmetry detects early risk of tracheal anastomotic complications after lung transplantation.

Healing of tracheal anastomosis after en bloc double-lung or heart-lung transplantation was analysed with the aid of endoscopic laser Doppler flowmetry in 7 patients (group I) with successful bronchial artery revascularization (BAR) and in 5 patients (group II) without or with failed BAR. Fifteen patients undergoing coronary surgery served as a control group. Airway anastomotic index (AAI) was used to express the ratio of Doppler flowmetry values between donor and recipient airway.
