RESUMO
This study reports the case of an 87-year-old woman who presented with a nonresolving haematoma 13 weeks following tibiotalar arthrodesis surgery on her right ankle using a retrograde nail. This was revealed by angiography to be a pseudoaneurysm of the anterior tibial artery. The patient subsequently underwent endovascular stenting of the pseudoaneurysm and has had a successful recovery. This case highlights the need for awareness of both the normal arterial supply to the leg and ankle as well as the potential for anatomical variations. Arterial variation may be as high as 6.7% based on published findings from cadaveric studies. As pseudoaneurysm is a rare complication, a high index of suspicion is needed in order to avoid a missed or delayed diagnosis. We urge surgeons to keep in mind the potential for pseudoaneurysm when a patient presents with a nonresolving haematoma and arrange appropriate further investigations as needed.
RESUMO
Retrieval of polyps during colonoscopic procedures can be technically difficult and time consuming. This is particularly the case when attempting to retrieve large polyps intact through the anal canal of an anxious patient with a hypertonic sphincter. In this paper, we describe a simple technique that permits the complete removal of a large polyp intact by using a readily available theater instrument. The success rate of this procedure can be improved with the aid of simple instrument like a proctoscope.

A case of primary malignant melanoma in the mediastinum presenting as recurrent laryngeal nerve palsy is reported. Tissue biopsy at mediastinotomy yielded a diagnosis of malignant melanoma. The mass was fixed to the left aspect of the trachea and to the upper border of the left main bronchus and could not be removed surgically. Further extensive clinical and radiological investigations revealed no evidence of tumor elsewhere in the body.
