The Angelchik prosthesis causes long-term dysphagia in a high proportion of patients, severe enough in one-quarter to necessitate its removal. Its continued use cannot, therefore, be recommended.

Even though horsechestnut seed extract is likely to attenuate the pathogenesis of venous insufficiency and, in turn, facilitate venous ulcer healing, the current study did not statistically support such a claim. However, taking into account the small sample and insufficient power of the trial, and the significant improvement in wound slough and visit frequency, it appears that it may be useful in the management of venous leg ulcers.
