Surgical removal of self-expanding stents from the carotid artery: does the type of stent make a difference?

Purpose: To evaluate the degree of difficulty in surgically removing 2 different stent models placed in the canine carotid artery.

Methods: In 5 dogs, each carotid artery was stented with a braided Elgiloy self-expanding stent (BESES) on one side and a surface-spanning micro stent (SSMS) on the other. After 4 weeks, an arteriogram was obtained, and the stents were removed via direct surgical exposure.

Spontaneous recanalization of arterial occlusions: an unusual mechanism for symptomatic improvement.

Objective: Patients with infrainguinal occlusive disease may experience spontaneous symptomatic improvement. This is generally thought to be from augmented collateral circulation. This study reports another mechanism.

Overt colon ischemia after endovascular aneurysm repair: the importance of microembolization as an etiology.

Objective: The purpose of this study was to analyze the incidence, severity, and etiologic factors of the development of colon ischemia after endovascular aortoiliac aneurysm repair (EVAR).

Methods: During the last 9 years we performed 278 elective EVARs using a variety of grafts. To facilitate these repairs, one hypogastric artery (HA) was coil embolized in 109 patients and both HAs were coil embolized in 13 patients.

Single-layer continuous suture for gastrojejunostomy.

A variety of techniques are available for the construction of a gastrojejunostomy. Little information is available regarding the influence of anastomotic technique on functional outcome, particularly delayed gastric emptying and other postgastrectomy syndromes. Twenty-seven cases were reviewed in which single-layer continuous suture was used for gastrojejunostomy.
