- OBJECTIVE: to evaluate preoperative duplex as the sole investigation prior to lower limb reconstruction. Design retrospective analysis. MATERIALS AND METHODS: between January 1995 and December 1999, 157 of 329 surgical interventions for chronic infrainguinal arterial or aneurysmal disease were performed without preoperative angiography. RESULTS: in patients undergoing femoral artery endarterectomy, the extent of the stenosis and the status of the distal deep femoral artery were correctly diagnosed with duplex scanning in all but one patient. Duplex scan findings in patients undergoing infrainguinal bypass procedures were in agreement with the findings obtained from on-table angiography in regard to the selection of optimal outflow anastomotic sites in 123 (98%). Duplex scanning correctly evaluated the status of runoff in 113 (90%). There were no significant differences in 30-day occlusion rate and patency at 12 months between reconstructions performed with and without preoperative angiography. CONCLUSION: in patients with conclusive duplex scan findings there is no need to perform angiography prior to lower limb reconstruction.

- AIM: To evaluate the role of duplex scanning in the selection of patients with infrainguinal arterial occlusive disease for percutaneous transluminal angioplasty (PTA). MATERIAL AND METHODS: From January 1995 through May 2000, 702 patients (952 limbs), with chronic lower extremity ischemia due to infrainguinal atherosclerotic disease diagnosed by duplex scanning, were retrospectively studied. Diagnostic angiography (130 limbs) or infrainguinal PTA (108 limbs) was performed in 238 limbs. Two investigators retrospectively analyzed the duplex examinations and angiographies in a blinded manner and used similar criteria for the interpretation of lesions suitable or not suitable for PTA. RESULTS: The superficial femoral, popliteal and crural artery lesions were correctly selected for PTA in 85%, 66% and 32%, respectively. The accuracy, sensitivity, specificity, negative predictive value and positive predictive value of duplex scanning to appropriately categorize femoropopliteal lesions as suitable or unsuitable for PTA were 89%, 83%, 92%, 94% and 78%, respectively. The accuracy of duplex scanning for predicting the performance of infrainguinal PTA was 83%. CONCLUSION: Duplex scanning has an important impact on the selection of treatment modalities in limbs with infrainguinal arterial occlusive disease. Femoropopliteal lesions can be reliably selected to PTA according to duplex scan findings.

Surgical reconstruction without preoperative angiography in patients with aortoiliac occlusive disease

- The objective of this study was to evaluate the feasibility of performing surgical reconstructions in patients with aortoiliac occlusive disease with findings obtained solely from duplex scanning. Between January 1995 through December 1999, among 112 patients who underwent surgical intervention due to aortoiliac occlusive disease, 44 were operated on with findings obtained solely from preoperative duplex scanning. Deviations from preoperatively planned surgical interventions according to duplex scan findings and the outcome were analyzed. Our results showed that surgical reconstructions for treatment of aortoiliac occlusive disease can be safely performed by using duplex scanning as the sole preoperative diagnostic modality in patients with conclusive duplex scan findings.

Effekter av vinterdäck : en kunskapsöversikt

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Choice of winter tyres has, from mainly being a matter of safety and economic costs for wearing of road pavements, during later years also become a matter of inhalable particles formed during pavement wear from studded tyres and their negative effects on public health. Further, the tyres' effects on environment and noise have been illustrated in several studies. The issue is also complicated by the fact that tyre choice effects on traffic safety have several components, including such diverging parameters as friction and behaviour. Finally all aspects have to be evaluated from a socioeconomic point of view for society to be able to decide which kind of distribution of tyre types that is the most profitable. This report is a summary of current knowledge in this complex research field.
