Bipolar radiofrequency-induced thermotherapy of great saphenous vein: Our initial experience.

The incidence of varicose veins in lower limbs is increasing in the Indian subcontinent. With the advent of radiofrequency ablation (RFA), an effective minimally invasive technique is now available to treat varicose veins. RFA can be performed with either unipolar or bipolar probes.

Covered coronary stent grafts as a treatment option for carotid-cavernous fistulas: our initial experience.

Treatment of Type 1 carotid-cavernous fistula (CCF) is complex and endovascular stent grafting is proving to be an excellent technique not only in successful treatment of fistula but also preserving patency of parent artery. We describe our initial experience in the use of covered coronary stent grafts in the treatment of three patients with Type 1 post-traumatic CCF. All patients were successfully treated with placement of stent grafts.

Outcomes of endovascular coiling of anterior communicating artery aneurysms in the early post-rupture period: a prospective analysis.

Background: There have been significant advances in the technical aspects of endovascular therapy of cerebral aneurysms. Anterior communicating artery (Acom A) aneurysms were traditionally treated by surgical clipping. Endovascular coiling has the distinct advantage of being minimally invasive and can be performed anytime during the course of subarachnoid hemorrhage (SAH).

Predilatation of a stenotic ostium of a bronchial artery, followed by embolization in recurrent hemoptysis.

Bronchial artery embolization may be the only life-saving procedure available in a patient presenting with massive hemoptysis. Rarely, selective catheterization of these vessels may be rendered difficult due to a stenotic ostium. This may result in closure of the vessel or absence of forward flow after the stenotic segment is crossed with a diagnostic catheter or a microcatheter.

Technical note: A simple and effective CO 2 delivery system for angiography using a blood bag.

Several angiographic techniques have been developed to image the arterial system, the commonest using iodinated contrast media. Useful as they may be, they are not without disadvantages. One other modality is angiography using CO 2 .

Arterial interventions in gastrointestinal bleeding.

The diagnosis and management of gastrointestinal (GI) bleeding are complicated. A multitude of pathologic processes results in GI bleeding, and often, the bleeding is intermittent in nature. Of the available diagnostic tools, angiography has been the gold standard.
