Safety and efficacy of superselective angioembolization in control of lower gastrointestinal hemorrhage

Transarterial embolization in acute colonic bleeding: review of 11 years of experience and long-term results

“…Additionally, identifying the source of bleeding has been demonstrated to be very useful to show the radiologist the target artery before the angiography. Recent reports have demonstrated the safety and efficacy of this procedure [22][23][24].…”

Successful endovascular embolisation of a jejunal artery aneurysm

“…(7)(8)(9) However, with the widespread use of CT angiography, there is increased detection of asymptomatic splanchnic artery aneurysms, in which treatment by angioembolisation has been shown to be effective as a first-line treatment with few complications and low recurrence rates. (2,5,(7)(8)(11)(12)(13)(14)(15) First described in 1974, angiographic diagnosis and treatment of gastrointestinal haemorrhage has since progressed significantly with advances in microcatheter technology, digital fluoroscopy and increased experience of interventional radiologists. Numerous reports have documented its safety and high rates of success of over 90%.…”

Long-term results of microcoil embolization for colonic haemorrhage: how common is rebleeding?

“…[24][25][26][27] The decision to use coil embolization over colonoscopy, however, remains limited by the lack of long-term follow-up data that assesses the overall durability of this minimally invasive therapy. Additionally, prior published data on endovascular technique is limited by a majority of studies using a combination of different embolic agents to manage lower GI bleeding, consequently confounding the evaluation for efficacy of any one single agent.…”

“…Additionally, prior published data on endovascular technique is limited by a majority of studies using a combination of different embolic agents to manage lower GI bleeding, consequently confounding the evaluation for efficacy of any one single agent. 4,[11][12][13][14][15][17][18][19]25,27,28 The present study sought to address this concern by examining both early and delayed rebleeding rates in patients managed specifically by superselective microcoil embolization, yielding rates of 11.5% and 15.3%, respectively. These findings take an initial step at showing the ability to achieve long-term haemostasis in most patients treated by endovascular coiling alone.…”

“…Additionally, as most other published literature on transcatheter embolization is confounded by the usage of a variety of embolic agents, the results from this study show the overall low risk of ischaemia when microcoils are used in a superselective manner. 4,[11][12][13][14][15][17][18][19]25,27,28 The belief is that superselective coiling limits the area of embolization to the diseased or actively bleeding segment of large bowel in such a fashion that arrests bleeding but avoids end organ necrosis and ischaemia. 3 This is in contrast to other embolic agents such as particles, gelatin sponge or liquid embolic (i.e.…”
