1. Clinical presentation, prognostic factors and epidemiology of ischemic bowel disease in the very old
Sammanfattning : Background: Acute ischemic bowel disease (AIBD) is a potentially death-threatening vascular emergency predominantly affecting the elderly (>65 years). The prognosis is dismal and early diagnosis and treatment is of vital importance for the outcome. Clinical presentation is unspecific. The five studies were retrospective. LÄS MER
2. Percutaneous Nephrostomies : Planning for an Optimal Access, Complications, Follow-up and Outcome
Sammanfattning : Percutaneous nephrostomy (PCN) is a well-established intervention performed to divert urine from the collecting system in ureteric obstruction or as a prelude to interventional procedures such as stent placement or percutaneous nephrolithotripsy (PCNL). The aim of this thesis is to enhance planning for an optimal insertion of PCN, investigate complications, long-term management, follow-up and outcome in patients with PCN treatment and to increase accuracy in CT-guided punctures.

3. Optimisation of radiographic imaging by means of factorial experiments
Sammanfattning : In the optimisation process of radiographic imaging, factorial designed experiments can be applied. The parameters (factors) are varied together instead of one at a time, making it possible to discover interactions between the factors as well as main influences of them on the result variable.
