דימות מערכת כלי-הדם מתבסס בעיקר על צינתור, תוך הסתייעות בחומר-ניגוד הבנוי על תרכובות המכילות יוד. ההתפתחות הטכנולוגית בתחום התהודה המגנטית מאפשרת דימות מדוייק של כלי-הדם המרכזיים וההיקפיים לאחר הזרקת חומר-הניגוד גדוליניום, באיכות המתחרה בצינתור, וזאת מבלי לחשוף את הנבדק לסכנות הכרוכות בצינתור ובהסתייעות בתרכובות היוד. הצגתו של אמצעי דימות חדיש זה והכרה שלו, על יתרונותיו וחסרונותיו, לרופאים שאינם רופאי דימות, ישפר את איבחון החולים הלוקים במחלות כלי-הדם.

The traditional treatment of acute colonic obstruction, usually caused by malignant tumor, is a 2-stage surgical procedure. The first operation is emergent and includes primary tumor resection and end colostomy followed by scheduled colostomy closure. These operations are associated with high mortality and morbidity. Recently, insertion of self-expanding metallic stents for temporary colonic decompression has been was introduced. With this new technique colostomy can be avoided in the acute phase.

In advanced colonic cancer stent-insertion is the only palliative treatment. It is done in the radiology department under fluoroscopic guidance. We present 2 cases of malignant colonic obstruction treated successfully by stent insertion.

Percutaneous endovascular techniques are well established procedures in the management of peripheral vascular disease and visceral arterial stenosis. They are now being adapted for use in the carotid artery as well. 8 patients with 9 extracranial carotid artery stenoses were successfully treated by percutaneous angioplasty, following which in 4 of them 5 stents were inserted. The stenotic lesions were situated in the proximal internal carotid artery and in its bifurcation and also in the common carotid artery. The indications for angioplasty in these patients were the same as for surgery. There were no major complications. 1 patient had transient hemiparesis lasting a few hours, and another had bradycardia following balloon dilatation in the region of the carotid body. Percutaneous endovascular treatment of carotid artery stenosis is becoming a safe, feasible alternative to surgery.
