Aneurysmal rupture of the costo-cervical trunk in a patient with neurofibromatosis type 1: A case report.

INTRODUCTION: Rupture of blood vessels associated with neurofibromatosis type 1 (NF-1) is a rare but life threatening complication. We report the first case of an aneurysmal rupture from the costocervical trunk in a NF-1 patient treated by endovascular embolisation. PRESENTATION OF CASE: A 43 year-old gentleman with a past medical history of NF-1 presented with sudden onset left sided neck swelling. A computed tomography (CT) revealed a large cervical haematoma, which was causing airway compromise, requiring the patient to be intubated. Percutaneous embolisation of the bleeding vessel from the costo-cervical trunk was performed with successful haemostasis and no immediate complications. A repeat CT scan showed a reduction in the original cervical haematoma. However, six days post embolisation, the patient arrested with complete whiteout of the left hemithorax. DISCUSSION: CT angiography is the gold standard for diagnosis of an aneurysmal rupture in NF-1 patients, and percutaneous embolisation is the preferred modality in patients who are haemodynamically stable due to arterial fragility and high intra operative mortality rates. The increasing haemothorax could be explained by the original cervical haematoma draining down into the pleural space, or the possibility of a new second bleed. CONCLUSION: This is the first reported episode of bleeding from the costocervical trunk in NF-1 patients. Ruptured aneurysms require urgent CT angiography, if haemodynamically stable, and further input from the vascular surgeons and vascular radiologists.

Chronic groin sinus: an unusual complication of sterilisation clips.

We report the case of a patient presenting with a chronic groin sinus secondary to a tubal ligation clip migration (Filshie clip) 21 years after the laparoscopic sterilisation took place. Our case report adds to the small number of cases describing tubal clip migration with resultant local sepsis. Although this is a rare complication, it should be borne in mind for women who have undergone tubal clip ligation and present with recurrent or chronic groin, perineal or peri-anal sepsis.
