Angiosarcoma is a rare subtype of malignant vascular tumours which has been only anecdotally described in patients submitted to lower limb revascularization.
This paper reports a patient previously submitted to a femoropopliteal bypass using autologous great saphenous vein (GSV). Nine years after the initial surgery, a primary angiosarcoma of the thrombosed vein graft was diagnosed, requiring surgical resection. Rampant metastatic spread was documented despite primary tumour surgical resection with a dismal outcome within months.
Malignant transformation of autologous vein for lower limb revascularization is extremely rare and anecdotally described in the literature. It is a poorly studied complication with an aggressive behaviour. This report further reinforces the need for early recognition of this pathology.
血管肉瘤是一种罕见的恶性血管肿瘤亚型，仅在接受下肢血运重建的患者中偶有描述。
本文报告了 1 例先前接受自体大隐静脉（GSV）股腘旁路移植术的患者。在初次手术后 9 年，诊断出血栓形成的静脉移植物原发性血管肉瘤，需要手术切除。尽管对原发性肿瘤进行了手术切除，但仍有广泛的转移性播散，数月内预后不佳。
自体静脉用于下肢血运重建的恶性转化极为罕见，在文献中也有描述。这是一种研究甚少但具有侵袭性的并发症。本报告进一步强调了早期识别这种病理的必要性。
