BACKGROUND Hemorrhagic complications during EUS-guided pseudocyst drainage can occur, because the vessels on the internal wall of the pseudocyst might be compressed by the fluid and thus not visible on color Doppler or even power Doppler EUS. CASE PRESENTATION We report a case of an immediate internal spurting arterial bleeding precipitated during EUS-guided pseudocyst drainage which stopped ...

Extracranial carotid artery dissection may manifest as arterial stenosis or occlusion, or as dissecting aneurysm formation. Anticoagulation and/or antiplatelet therapy is the first-line treatment, but because it is effective and less invasive than other procedures, endovascular treatment of carotid artery dissection has recently attracted interest. We encountered two consecutive cases of trauma...

To evaluate the potential utility of a self-expandable intratracheal nitinol stent with flared ends for the treatment of tracheal collapse in dogs, endotracheal stenting therapy was performed under fluoroscopic guidance in four dogs with severe tracheal collapse. During the 4 to 7 month followup, after stent implantation, clinical signs, including dyspnea and respiratory distress, dramatically ...

Introduction Tracheobronchial stenoses or fistulas caused by benign or malignant diseases are life-threatening and present as respiratory distress symptoms.Airway stent insertion is an effective and widely used method to manage this condition. When the stenoses or the fistulas exist in the lower trachea,main carina, and main-stem bronchi, the insertion of one hinged stent or angled stent, or tw...

BACKGROUND Because transcatheter implantation of pulmonary valve is indicated for limited-size dysfunctional right ventricular outflow tract only as a balloon-expandable stent, we investigated the feasibility of a large-diameter self-expandable valved stent and the durability of the valve after >6 months. METHODS We made a nitinol-wire-based, self-expandable valved stent with leaflets made fr...

To address elastic recoil of vessel wall and intimal dissection that can follow balloon angioplasty, stents have been designed and these appear to produce more effective relief of obstruction. Of the two types of stents, namely, balloon expandable and self expandable, balloon expandable stents are most commonly used in children. The usefulness of stents in the management of vascular obstructive...

(VADA) necessitates an urgent treatment to prevent a fatal early rebleeding (1-3). The endovascular procedure has been suggested as a rational approach in the management of acute ruptured VADAs (1-4). Although stent-assisted coil embolization has been introduced as an effective endovascular procedure for both durable aneurysmal occlusion and parent artery preservation, some limitations were rep...

Esophageal perforation has a high rate of mortality. Many strategies have been advocated for its management. Therapeutic options are surgical repair or resection, endoscopic placement of self-expandable metallic stents or, in selected cases, conservative management.We describe a case of a 75-year-old man admitted to our hospital for forceful vomiting since 24 hours. The patient was treated with...

OBJECTIVE To evaluate the feasibility and satefy of transcatheter aortic valve implantation in animals by using a new balloon-expanding valved stent. METHODS The balloon-expandable stent is made from cobalt-based alloy material and designed with a tubular, slotted structure. Fresh bovine pericardium was treated, sutured and fixed on the balloon-expandable stent. Ten healthy sheep (five males ...
