Transcatheter embolization of bronchial arteries in the treatment of haemoptysis

Abstract

Background. Massive haemoptysis is a clinical state characterized by the expectoration of blood at a rate of 300-600 mL/24 h, thus causing life-threatening asphyxia. The aim of our study is to review use of transcatheter bronchial artery embolization (BAE) in the treatment

Percutaneous transcatheter arterial embolization in haemodynamically stable patients with blunt splenic injury

“…The distal splenic artery embolization is the method of choice for the management of a haemorrhage which originates from a distal branch of the splenic artery. This type of embolization is usually performed with microcoils and/or gelatin sponge pledgets that are injected through a microcatheter 2,8–11. This technique achieves haemostasis to the injured parts while preserving the perfusion to the remainder of the spleen.…”

“…Although the nonsurgical management of stable blunt splenic injuries in adults has gained popularity in recent years, the initial choice of surgical versus nonsurgical management remains controversial. However, embolization is also wildly used for another indications with much less controversial results 2,3. The controversy of the splenic arterial embolization has been attributed to the relatively high failure rate of such a treatment (10–31%), with a resultant need for secondary splenectomy, and to the potential of missing other intra-abdominal injures that require laparotomy.…”

“…The most widely accepted indication for TAE is evidence of the arterial injury on a computed tomography (CT) scan. In cases of the arterial injury, embolization is performed with microcoils or gelfoam particles as distally as possible, in a small arterial branch that supplies the segment in which the extravasation is detected, to preserve perfusion to the remaining splenic parenchyma 1,2. We report on a patient with blunt splenic trauma who was successfully treated by the supraselective embolization with microspheres.…”

The splenic transcatheter arterial embolization (TAE) has been proposed to reduce the risk of nonsurgical management failure in adults and children.…”
