Internal iliac artery occlusion using a stent-graft tunnel during endovascular aneurysm repair: a new alternative to coil embolization.

Purpose: To report a new endovascular technique for internal iliac artery (IIA) occlusion during stent-graft treatment in patients with aortoiliac aneurysm.

Technique: Stent-grafts measuring 20 to 28 mm in diameter and 37.5 mm long were deployed at the iliac bifurcation to occlude the IIA at its origin.

Distal internal iliac artery embolization: a procedure to avoid.

Objectives: Internal iliac artery (IIA) coil embolization as an adjunct to endovascular stent grafting (ESG) is common practice for treating abdominal aortic aneurysm (AAA) in patients with a substantially enlarged common iliac artery requiring extension of the stent-graft limb into the external iliac artery. The literature describing pelvic ischemia in association with IIA coil embolization contains conflicting reports of symptom severity. We studied IIA occlusion outcome as a function of coil placement in the IIA.

Bell-bottom aortoiliac endografts: an alternative that preserves pelvic blood flow.

Objective: Dilated common iliac arteries that complicate aortic aneurysm stent grafting usually have been managed with endograft extension across the iliac artery bifurcation with internal iliac artery (IIA) occlusion. We studied 25 patients with significant common iliac artery (CIA) dilation treated with two methods: endograft extension across the iliac bifurcation or a new approach with a flared cuff within the CIA that preserves the IIA.

Methods: Of 86 patients with abdominal aortic aneurysm (AAA) who underwent bifurcated endovascular stent grafting (ESG), 25 (29.

Transient radicular irritation (TRI) after spinal anaesthesia in day-care surgery.

Background: A high incidence of backache with radiating pains to the lower extremities, termed transient radicular irritation (TRI), has been reported following the use of 5% hyperbaric lidocaine. This has been attributed to a neurotoxic reaction.

Methods: A retrospective audit has been carried out in our hospital on the postoperative anaesthetic records of all patients from the 1st of January 1993 to the 1st of September 1996, who received spinal anaesthesia with either hyperbaric lidocaine or hyperbaric bupivacaine for day-care surgery.
