Background:
Head and neck lymphoedema secondary to jugular lymphadenectomy is a severe issue, without efficient solution. Successful treatment of lymphoedema of the upper and lower limbs has become possible with supermicrosurgical lymphaticovenular anastomosis. The technique based on two end-to-side anastomosis is named π-shaped lymphaticovenular anastomosis. We have evaluated this method for chronic head and neck lymphoedema.
Methods:
From November 2010 to April 2011, four patients with a chronic head and neck lymphoedema were treated by π-shaped lymphaticovenular anastomosis. Three patients had a unilateral lymphoedema, and one patient had a bilateral lymphoedema. The mean age of the patients was 63.2 years (range, 46-77 years). The mean duration of the lymphoedema was 2.6 years (range, 1-5). Every patient was operated under local anaesthesia through a face-lift skin incision. One π-shaped lymphaticovenular anastomosis was performed at each operative site.
Results:
The average operative time to perform one π-shaped lymphaticovenular anastomosis was 1.9 h (range, 1.8-2.5). The calibre of lymphatic vessels used for lymphaticovenular anastomosis ranged from 0.3 to 0.7 mm (average, 0.5). A venous back-flow was found in seven lymphaticovenular anastomosis (70%). Three patients (75%) had a qualitative improvement of skin tissue and a significant circumferential reduction after surgery. The average circumferential differential reduction rate was 3.7% (range, 0.6-7.8) (p=0.006). The average cross-sectional area differential reduction rate was 7.2% (range, 1.2-15.1) (p=0.007). The average volume differential reduction rate was 6.9% (range, 2-14.8) (p=0.05).
Conclusions:
The authors present a new option to treat head and neck lymphoedema. π-Shaped lymphaticovenular anastomosis is an effective method to reduce the severity of skin tissue fibrosis and lymphoedema volume. Further studies with larger groups of patients are required to confirm the outcome of this preliminary study. EBM Level=level 4.

The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
