بررسی محل های شایع تنگی و انسداد در بیماری انسدادی شرایین اندام های تحتانی در 100 مورد آنژیوگرافی DSA

Background: Occlusive disease of lower extremity arteries are so common and cause severe stenosis or complete local obstruction in arteries as it need treatment. The treatment could be surgery or interventional procedures like angioplasty or implant of stent. Sometimes such treatments are impossible because of severity or location of complication and cause amputation.The purpose of this study is an assessment about more common locations of arterial obstruction in lower extremities which is necessary for treatment planning and prediction for efficient supplements. Methods: In this descriptive study from 2000 until 2005, 100 patients with occlusive disease of lower extremity arteries who underwent angiography in medical imaging center of Imam Khomeini hospital in Tehran had been studied according to location of arterial obstructions. In the point of view of homodynamic conditions, obstructions over 70% consider important, so all of these patients had arterial obstruction over 70% up to 100%. Results: Our findings show that the most common locations of arterial obstruction in lower extremity are superficial femoral artery (47%), arteries of leg (21%) and iliac arteries (19%). Conclusion: This study can show appropriate assessment of the most common locations of arterial obstruction in lower extremity to predict supplements that may be needed for treatment of these patients.
