Combined Endovascular Treatment with Distal Radial Artery Coil Embolization and Angioplasty in Steal Syndrome Associated with Forearm Dialysis Fistula.

Purpose: The present study was performed to define the results of the endovascular treatment with angioplasty and distal radial artery embolization in ischemic steal syndrome associated with forearm arteriovenous accesses.

Method: The cases referred to our interventional radiology unit with symptoms and physical examination findings suggestive of ischemic steal syndrome were retrospectively evaluated first by Doppler ultrasonography, and then by angiography. Cases with proximal artery stenosis were applied angioplasty, and those with steal syndrome underwent coil embolization to distal radial artery.

Effect of radiological extent and severity of bronchiectasis on pulmonary function.

Background: The aim of this study was to ascertain the effect of the extent and severity of bronchiectasis as determined with high-resolution computed tomography (HRCT) on lung function in patients with pure bronchiectasis, bronchiectasis and asthma, and bronchiectasis and chronic obstructive pulmonary disease (COPD).

Methods: One hundred nineteen patients (71 with pure bronchiectasis, 25 asthmatic patients with bronchiectasis, and 23 COPD patients with bronchiectasis) underwent HRCT and pulmonary function tests. Computed tomography features were scored by the consensus of 2 radiologists.

Ergotamine-induced lower extremity arterial vasospasm presenting as acute limb ischemia.

Ergotamine-induced limb ischemia is rare and usually results from an accidental overdose. Several agents, including erythromycin and tetracycline, raise serum ergotamine levels and augment its effect. We present a case of acute lower limb ischemia with characteristic angiography findings of diffuse arterial spasm resulting from use of ergotamine and an erythromycin derivative, clarithromycin.

Compression ratios were compared with those of 34 age- and sex-matched asymptomatic subjects.

The prevalence and clinical predictors of incidental atherosclerotic renal artery stenosis.

Objective: To evaluate the prevalence of incidental renal artery stenosis due to atherosclerosis and associated risk factors in patients with peripheral arterial disease (PAD).

Materials And Methods: To determine renal artery stenosis, aortofemoropopliteal digital substraction angiographies (DSA) of 629 consecutive patients with PAD were prospectively reviewed. Angiographies were performed as catheter angiography with automated pump injection.

Laparoscopic management of gallbladder duplication.

Gallbladder duplication is a rare condition. Because laparoscopic cholecystectomy is the primary treatment modality for the diseased single gallbladders, it should be the choice of treatment for double gallbladders. However, preoperative imaging methods may be unsatisfactory for the correct diagnosis.

Iliac vein compression syndrome: outcome of endovascular treatment with long-term follow-up.

Objective: To retrospectively evaluate technical success and long-term outcome of endovascular treatment in patients with iliofemoral deep vein thrombosis (DVT) due to iliac vein compression syndrome (IVCS).

Materials And Methods: Between March 2003 and September 2006, 36 consecutive patients (26 women [72%], 10 men, mean age 50+/-18 years) with acute or chronic iliofemoral deep vein thrombosis due to iliac vein compression syndrome were evaluated for outcome of endovascular treatment. Stent patency was estimated by using the Kaplan-Meier method.

Ultrasonographic diagnosis of iliac vein compression (May-Thurner) syndrome.

Iliac vein compression syndrome (IVCS), also known as May-Thurner syndrome, is the result of compression of the left common iliac vein between the right common iliac artery and overlying vertebrae. The most common clinical presentation is left lower extremity deep vein thrombosis. Rarely, a patient with IVCS can present with obstruction of venous outflow, without deep vein thrombosis.
