[The marginal vein-Still a rare entity: case series of 16 patients]. / Die Marginalvene ­ nach wie vor eine seltene Entität: Fallserie von 16 Patienten.

BACKGROUND: The marginal vein (MV) is a congenital, predominantly venous vascular malformation, which is based on a lack of regression of the embryonic venous system in the lower extremities and is associated with a variety of complications. So far, no uniform treatment regimens have been described in the literature. OBJECTIVE: What are the treatment strategies and outcomes in patients with a MV? MATERIAL AND METHODS: In the period from 1 January 2008 to 31 December 2020, all patients treated at the University Hospital Augsburg with MV were retrospectively reviewed. RESULTS: The median age at the time of diagnosis was 14.8 years (3-42 years). Out of 16 patients 12 had a leg length difference, 75% of patients (12/16) already had chronic venous insufficiency (CVI) at the time of diagnosis of MV. Open surgical removal of MV was performed as first-line treatment in 31.3% (5/16) patients. The MV was primarily closed by endovenous laser therapy (EVLT) in 1/16 patients, 15/16 patients were treated with redo procedures and 2.6 ± 2.4 (mean±SD) redo procedures were performed per patient in follow-up. The mean follow-up was 8.1 years. DISCUSSION: In order to prevent/avoid progression of CVI and thrombosis prophylaxis, the MV should be closed/removed promptly after diagnosis. The use of conventional surgical techniques for the removal of MV seems to have an advantage over treatment with minimally invasive procedures in terms of the number of secondary interventions required.

Long-term results after surgical treatment of nonparasitic hepatic cysts.

BACKGROUND: Studies evaluating surgical success in patients with benign liver cysts focus on cyst recurrence. The aim of this study was to evaluate the efficacy of surgical treatment with regard to clinical complaints. MATERIALS AND METHODS: Between 1995 and 2007, 99 patients (M:F 1:7.25) with symptomatic, benign, nonparasitic liver cysts (77 simple liver cysts [SLCs], 22 polycystic liver disease [PCLD]) underwent surgical treatment (77% laparoscopic surgery, 23% open surgery). Perioperative parameters (including morbidity) were evaluated. Moreover, a questionnaire was completed by 65 patients monitoring subjective complaints focusing on abdominal pain, vegetative symptoms, and dyspnea pre- and postoperatively (mean follow-up 76 months). RESULTS: Severe complications occurred in 7 patients. Abdominal pain, vegetative symptoms, and dyspnea were significantly improved in SLC patients. In PCLD patients abdominal pain and dyspnea were significantly decreased, whereas vegetative symptoms were unaffected by surgery. The symptom recurrence rate for SLC patients was significantly lower compared with PCLD patients (41% vs 66.6%). CONCLUSION: Indications for surgical treatment of PCLD should be well considered and limited to a selected group of patients.
