Endovascular treatment of descending thoracic aortic disease. A single center experience.

Aim: Aim of the study was to assess if endovascular treatment is a feasible alternative in patients with descending thoracic aortic disease.

Methods: Seventy-three patients were admitted for stent-grafting of descending thoracic aortic disease during the period 1997-2008. The majority of the patients had aneurysm (35) or type B dissection (21), but also traumas, penetrating ulcers and other conditions were treated.

DynaCT in pre-treatment evaluation of aortic aneurysm before EVAR.

Objective: DynaCT(®) is a method for obtaining computed tomography (CT)-like images using a C-arm system. Our aim was to compare the accuracy of these images to multidetector CT (MDCT) images prior to endovascular aortic repair (EVAR).

Methods: A non-consecutive group of 20 elective patients were prospectively exposed to MDCT and one additional DynaCT before EVAR.

[Recurrence and survival after surgical treatment of lung cancer].

Background: 2500 new cases of lung cancer are diagnosed in Norway annually. Patients with limited disease can be operated, but many will die from the disease despite surgical treatment. The aim of the study was to review survival and recurrence, and factors which affect survival, in patients operated for lung cancer.

DynaCT during EVAR--a comparison with multidetector CT.

Objectives: We have explored the usefulness of an on-table, cross-sectional radiological imaging (DynaCT) in endovascular aortic repair (EVAR). DynaCT images were compared to images from a regular multidetector (16 slice) CT. In the comparison, we tested the accordance of firstly 5 relevant clinical measurements and secondly the visibility of 9 anatomical areas in the two different types of images.

[Nine years' experience with endovascular treatment of abdominal aortic aneurysms].

Background: Endovascular repair of abdominal aortic aneurysm was started nine years ago at our institution. Our purpose was to evaluate the results over this period.

Material And Methods: From 1995 to 2003, a total of 148 patients were treated for infrarenal abdominal aortic aneurysms by endovascular repair.

Combined open and endovascular treatment of complex aortic disease.

The purpose of this article is to report whether combined open and endovascular treatment could be applied in patients with complex aortic disease. A retrospective study including four patients with complex aortic disease was undertaken. In all patients, extra-anatomic bypass to the visceral arteries was made through a laparotomy while the aortic lesion was repaired by stent grafting.

[Interventional radiology in Norwegian hospitals].

Background: In recent years, interventional radiology has gained in importance in patient treatment. In order to assess the impact of this trend, the executive committee of the Norwegian Society for Interventional Radiology made a registration of all interventional procedures in Norwegian hospitals in the year 2000.

Material And Methods: Data were collected by a questionnaire sent to all Norwegian hospitals.

Type III endoleak from a thoracic aortic stent-graft.

Purpose: To present an as yet unreported late complication of an Excluder thoracic endograft.

Case Report: A 78-year-old man underwent surgery for a ruptured type V thoracoabdominal aortic aneurysm in 1996. Four years later, an aneurysm was detected in the proximal thoracic aorta and repaired with 2 Excluder endoprostheses.

Endovascular treatment of type B aortic dissections.

The purpose is to describe our experience with endovascular treatment of type B aortic dissections. Five patients were treated for complications following type B dissections like, false channel aneurysm formation, rupture and arterial obstruction. They were treated in general anaesthesia using a 'homemade' endoprosthesis or a commercially available endoprosthesis (Excluder) deployed during fluoroscopy.

The inflammatory response following treatment of abdominal aortic aneurysms: a comparison between open surgery and endovascular repair.

Objectives: to compare the inflammatory response following endovascular and conventional AAA repair.

Design: prospective study.

Patients And Methods: ten patients were selected for open surgery (OPEN) and ten for endovascular (ENDO) AAA repair.

Endovascular treatment of abdominal aortic aneurysms in Norway: the first 100 patients.

Objectives: to present the first 100 consecutive endograft implantations for abdominal aortic aneurysms (AAAs) in Norway.

Design: retrospective study of 100 consecutive graft implantations, performed at five University Hospitals during 1995 to 1997.

Material: one hundred patients with a median age of 70 years were included.

Endovascular Treatment of Aortic Disease.

A review is given of endovascular treatment for AAA, thoracic aortic aneurysms, dissections as well as complications following previous aortic surgery. In several of these conditions endovascular treatment has advantages like a reduced operative trauma, shorter stay in hospital, and the possibility of treating patients who would have been unfit for open surgery. On the other hand, problems like endoleak, deformation of the endoprosthesis, retrograde filling of the aneurysmal sack, and graft limb occlusion need to be solved before the place of endovascular treatment can be defined.

[Endovascular treatment of thoracic aortic aneurysm].

Two patients with aneurysms of the descending thoracic aorta were treated by endovascular technique. One of the patients was also treated for an infrarenal aortic aneurysm by open surgery during the same procedure. The other patient had chest pain, probably caused by an impending rupture.

Ultrasound imaging during endovascular abdominal aortic aneurysm repair using the Stentor bifurcated endograft.

Purpose: To evaluate different ultrasound modalities during implantation and follow-up of endovascular grafts for abdominal aortic aneurysm (AAA) exclusion.

Methods: Between February 1995 and May 1996, 18 patients (14 men; aged 49 to 80 years, mean 67) were treated with endovascular intervention for infrarenal AAA. Seventeen patients received Mialhe Stentor bifurcated grafts, while one patient was treated with a straight graft for pseudoaneurysm.

Regional anesthesia for endovascular treatment of abdominal aortic aneurysms.

Purpose: To investigate the feasibility of regional anesthesia for endovascular repair of abdominal aortic aneurysms (AAAs).

Methods: Since February 1995, 21 patients (17 men and 4 women; median age 67 years, range 49 to 80) have been treated with endovascular technique for true infrarenal AAA using Mialhe Stentor bifurcated grafts. A single dose of spinal anesthesia combined with epidural anesthesia was used in all procedures.

[Endovascular treatment of abdominal aortic aneurysms].

Eight patients, six men and two women (mean age 67.3 years) were treated for infrarenal abdominal aortic aneurysm by endovascular technique. A bifurcated graft (Mialhe Stentor, Min Tec, France) was used in all cases.

Catheter malfunction and thrombus formation on double-lumen hemodialysis catheters: an intravascular ultrasonographic study.

Intravascular ultrasound imaging (IVUS) is a new method that permits in vivo visualization of central venous catheters with hitherto unknown image resolution. It provides information not only about thrombus formation, but also about catheter movement, catheter malposition, and vessel wall injuries. In the present investigation the method was applied to evaluate the frequency of thrombus formation on double-lumen hemodialysis catheters and its significance for catheter malfunction.

Angiographic and intravascular ultrasonographic findings after endovascular stent implantation.

The study was an attempt to evaluate the benefit of intravascular ultrasound imaging (IVUS) as a supplement to follow-up angiography after endovascular stent implantation. A consecutive series of 15 patients underwent stent implantation in the peripheral or coronary arteries. Ten Palmaz stents, 3 Palmaz-Schatz stents and 2 Wallstents were used.

[Medial femoral neck fractures treated with hip compression screw. A product control study].

311 medial femoral neck fractures (213 of them displaced) treated with a hip compression screw were studied retrospectively. 90 patients were treated with a primary hemiprosthesis during the same period. Fixation was lost in the case of seven fractures within three months after the operation.

Sarcoma following irradiation for breast cancer. Report of three unusual cases including one malignant mesenchymoma of bone.

Three cases of sarcoma developing after irradiation for breast cancer are reported. A malignant mesenchymoma in the sternum--a combination of osteogenic sarcoma and rhabdomyosarcoma--is the first documented case of its kind occurring after radiation therapy. Of the other two tumors one was an extraskeletal osteogenic sarcoma in the soft tissues of the thoracic wall and one a rhabdomyosarcoma in the axilla.
