Superior mesenteric artery dissection as a complication of an endovascular attempt to treat aneurysms of the pancreaticoduodenal arteries.

A case of iatrogenic dissection of the superior mesenteric artery (SMA) in a 42-year old woman during an attempt of endovascular treatment of aneurysms of the pancreaticoduodenal arteries coexisting with a stenosis of the coeliac trunk is presented. The dissection occurred most probably during insertion of an introducer sheath into the SMA. The patient at that moment reported a short-lasting abdominal pain and after that remained asymptomatic.

Abdominal aorta aneurysm: Case report of high radiation dose during stent-graft implantation.

This study is a case report regarding a possible problem of high radiation dose during stent-graft implantation. Before deciding on how to treat an aneurysm (stent grafting or traditional surgery), possible complications such as difficult anatomical conditions and diseases of the aorta and iliac arteries should be considered to avoid potentially high doses of radiation. In case of this patient, it was very difficult to introduce a guidewire through the contralateral limb into the body of the graft due to tortuosity and kinking of iliac arteries.

Patients' radiation doses during thoracic stent-graft implantation: the problem of long-lasting procedures.

Background: This article investigates patient radiation doses during implantation of thoracic stent-graft. Aortic stengraft implantation can be disturbed by many factors, which, in turn, lead to prolongation of the procedure time and, as a consequence, increase the radiation dose.

Methods: Measurements of radiation length (fluoroscopy and exposure), air kerma (AK) in grays, and dose-area product in grays·square centimeters were conducted simultaneously in 100 patients.

Clinical factors increasing radiation doses to patients undergoing long-lasting procedures: abdominal stent-graft implantation.

Background: An important negative factor of EVAR is the radiation acquired during long-lasting procedures. The aim of the study was to document the radiation doses of EVAR and to discuss potential reasons for prolongation of radiological procedures.

Material/methods: Dose-area product (DAP) (Gy cm²) and air kerma (AK) (Gy) obtained during EVAR from 92 patients were analyzed retrospectively in regards to body mass index (BMI), angulations of aneurysm neck, length of aneurysm neck and occurrence of tortuosity of iliac arteries.
