1. 1. The role of duplex scanning in the management of carotid artery disease

   Författare :Karl Logason; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Duplex scanning; Doppler spectral analysis; duplex criteria; Doppler angle of insonation; carotid artery stenosis; carotid endarterectomy; spontaneous cervical artery dissection; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

   Sammanfattning : Extracranial carotid artery disease, mainly due to atherosclerosis, is a common cause of stroke. The risk for future stroke can be reduced in selected patients by carotid endarterectomy (CEA). Duplex scanning has been increasingly used for diagnosis of carotid artery disease. LÄS MER

3. 2. The impact of duplex scanning in the management of chronic lower limb arterial disease

   Författare :Annika Boström Ardin; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Duplex; Ultrasound; lower extremity; arterial; chronic ishemia; selection; surgery; PTA; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

   Sammanfattning : In patients with chronic lower extremity ischemia in which endovascular or surgical intervention is considered non-invasive evaluation by duplex scanning provides important anatomical and hemodynamic information. The aim of this thesis was to evaluate the impact of duplex scanning in the selection of various therapeutic alternatives in limbs with lower extremity arterial insufficiency. LÄS MER

4. 3. Varicose Veins : Aspects on Diagnosis and Surgical Treatment

   Författare :Lena Blomgren; David Bergqvist; Gunnar Johansson; Lars Norgren; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Varicose veins; Venous insufficiency; Surgery; Duplex; Quality of life; Cost analysis; Kirurgi; Surgery; Kirurgi;

   Sammanfattning : Treatment for varicose veins (VV) is insufficiently evidence based and recurrence rates are high. The aim of this thesis was to study the long-term results after VV surgery, risk factors for recurrences and the effect of preoperative duplex scanning on recurrence rate, quality of life (QoL) and costs.

5. 4. Infrainguinal Percutaneous Transluminal Angioplasty in Limbs with Severe Lower Limb Ischaemia

   Författare :Anne-Marie Löfberg; Wojciech Cwikiel; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; infrainguinal; chronic ischaemia; percutaneous transluminal angioplasty; duplex; bypass grafts; Onkologi; Oncology; Onkologi; radiologi; Radiology;

   Sammanfattning : Infrainguinal bypass grafting is an established method in the treatment of patients with femoropopliteal and crural occlusive disease leading to critical lower limb ischaemia (CLI). However, complications related to surgical procedure are not negligible and percutaneous transluminal angioplasty (PTA) has emerged as an alternative. LÄS MER

7. 5. Texture based duplex-board layer segmentation

   Författare :Arash Fayyazi; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : A serial scanning electron microscopy images of paper was obtained by a slicing procedure The slicing procedure leads to misregistrations that have to be corrected. Two methods for registration of consecutive images are presented here.Duplex-board is used mainly for packaging liquids. It has a triple layer structure. LÄS MER
