    Lymph drainage of the upper limb and mammary region to the axilla: anatomical study in stillborns
    (2018) CUADRADO, Guilherme de Arruda; ANDRADE, Mauro Figueiredo Carvalho de; AKAMATSU, Flavia Emi; JACOMO, Alfredo Luiz
    Purpose We studied the lymphatic drainage of the upper limb and mammary region directing to the axilla to investigate whether independent pathways can be observed or whether anastomoses and shared drainage occur between them. This analysis aimed to assess the safety of axillary reverse mapping (ARM) in breast cancer treatment and to understand the development of lymphedema after sentinel lymph node biopsy (SLNB) alone. Methods Seven unfixed stillborn fetuses were injected with a modified Gerota mass in the peri-areolar area, palm and dorsum of the hands, formalin fixed, and then submerged in 10% hydrogen peroxide solution. Microsurgical dissection was then performed on the subcutaneous cellular tissue of the upper limb, axillary region, and anterior thorax to expose the lymphatic vessels and lymph nodes. Results The dye injected into the upper limb reached either the lateral axillary group, known to be exclusively responsible for upper limb drainage, or the anterior group, which is typically related to breast drainage. There was great proximity among the pathways and lymph nodes. Communicating lymphatic vessels among these groups of lymph nodes were also found in all studied cases. Discussion Lymphedema remains a challenging morbidity in breast cancer treatment. ARM and SLNB aim to avoid unnecessary damage to the lymphatic drainage of the upper limb. However, our anatomical study suggests that ARM may have potential oncological risks because preserved lymph nodes may harbor malignant cells due their proximity, overlapping drainage pathways, and connecting lymph vessels among lymph nodes.

    Aneurysm of the Fibular Vein: A Case Report
    (2018) SALEH, Samir Omar; ANDRADE, Mauro Figueired Carvalho de; CUADRADO, Guilherme de Arruda; SALEH, Kassem Samir; AKAMATSU, Flavia Emi; JACOMO, Alfredo Luiz
    Background: Aneurysms of the deep veins of the lower limbs are rare and often asymptomatic. Although natural history is unclear, these aneurysms have been associated with deep venous thrombosis and fatal pulmonary embolism events. To our knowledge, this case represents the fifth patient with isolated aneurysm of a calf vein described in the literature and the second one affecting the fibular vein. Methods: We report the case of a 20-year-old white man with an aneurysm of the fibular vein that we believe is the second case in the literature Results: After evaluation and diagnosis, the aneurysm was resected with full recovery of the patient. Conclusions: Treatment of this unusual condition seems to be mandatory for major thromboembolic events can be as high as 71% with 2 deaths, according to a review of 24 patients with popliteal vein aneurysms. Unlike proximal veins, where reconstruction is advisable, calf vein aneurysms can be safely managed by simple excision and ligature. In our patient, aneurysm resection eliminated symptoms, and good result was maintained in long follow-up.
