The Efficacy and Long-Term Outcome of Microcoil Embolotherapy for Acute Lower Gastrointestinal Bleeding

Objective

To evaluate the clinical efficacy as well as long-term clinical outcomes of superselective microcoil embolization for lower gastrointestinal bleeding (LGIB).

Materials and Methods

Between 1997 and 2009, 26 patients with intended transcatheter embolotherapy for LGIB were retrospectively reviewed. Embolization was performed only when the catheter could be advanced to or distal to the mesenteric border of the bowel. The main purpose of our study was to assess technical success, recurrent bleeding rate and complications. We also evaluated the long-term clinical outcome, including late recurrent LGIB, bowel ischemia and the survival rate.

Results

Twenty-two bleeding sources were in the territory of superior mesenteric artery and four in the inferior mesenteric artery. Technical success was achieved in 22 patients (84.6%). The target vessel of embolization was vasa recta in seventeen patients and marginal artery in the remaining five patients. Early rebleeding occurred in two patients (7.7%) and bowel ischemia in two patients, of whom the embolized points were both at the marginal artery. Delayed recurrent bleeding (> 30 days) occurred in two angiodysplasia patients. Five patients (19.2%) died within the first 30 days of intervention. Long-term follow-up depicted estimated survival rates of 58.2 and 43.1% after one, and five years, respectively.

Conclusion

Transcatheter embolotherapy to treat LGIB is effective with low rebleeding and ischemic complications. Considering the advanced age and complex medical problems of these patients, the minimal invasive embolotherapy may be used as both a primary and potentially definitive treatment of LGIB.     

Embolotherapy for persistent hemoptysis: The significance of pleural thickening

Elective embolotherapy for recurrent hemoptysis was evaluated for its effectiveness. Forty embolotherapeutic procedures were performed in 30 patients. In the short term, complete hemostasis was achieved in 16 of 40 procedures (40%) and significant improvement in another 16 procedures (40%). Long-term complete hemostasis was achieved in 14 of 34 procedures (41%) and significant improvement in 12 (35%). Embolotherapy was consistently more effective in patients who had no pleural abnormalities compared with those with pleural thickening. Long-term complete hemostasis was achieved in 7 of 10 procedures (70%) for the patients without pleural thickening and only 7 of 24 (29%) in patients with pleural thickening. Thus, pleural abnormalities negatively influence long-term effectiveness of embolotherapy.
