Extracranial aneurysms of the carotid artery in childhood are rare, and we found just nine cases described in the literature within the last 20 years. We report on the clinical appearance, diagnosis, and therapy of a carotid artery aneurysm in a 12-year-old girl and review the literature.

We report 96 patients (107 legs) with recurrence after varicose vein surgery. We define a recurrent varicose vein as a new transfascial insufficiency after incomplete interruption of the saphenofemoral as well as popliteal junction with reflux in the epifascial venous system. 92 patients underwent external primary surgery. Morphologically an insufficient high ligation of the V. saphena magna (Moszkowicz's operation) led in 30 cases to a recurrent varicose vein. In 47 cases an incomplete isolated, in 29 cases an incomplete saphenofemoral ligation during a Babcock procedure and in one case an incomplete saphenopopliteal ligation for V. saphena parva insufficiency were the reasons for the recurrence. As recurrent surgery we performed 106 ligations of the saphenofemoral junction. In 38 of these cases an isolated saphenofemoral ligation and in 68 cases an additional stage-adjusted ligation of the V. saphena magna were carried out. In one case of recurrent saphenopopliteal insufficiency a repeated ligation of the V. saphena parva was performed. The recurrence is an avoidable complication of a not perfect primary surgery. The main cause is an inadequate access with incomplete saphenofemoral or -popliteal ligation.
A major complication of portal and mesenteric vein thrombosis is acute bowel ischaemia resulting in infarction and requiring immediate resection of the involved segment. Sufficient collaterals can prevent acute haemorrhagic infarction, but bowel stenosis due to chronic ischaemia may develop. We report two cases of ischaemic jejunal stenosis occurring 4 weeks after successful treatment of portal and mesenteric vein thrombosis. Diagnosis of high-grade segmental stenosis of the jejunum was established by contrast medium radiography of the gastrointestinal tract. After laparotomy and resection of the stenosed jejunal segment, both patients recovered well from the operation and were released from hospital. Follow-up examinations revealed an unremarkable state of health. Ischaemic bowel stenosis should be considered in patients with recurring abdominal pain after mesenteric and portal vein thrombosis. A close follow-up of every patient after treatment for mesenteric and portal vein thrombosis should be carried out to ensure early diagnosis of this complication.
