Background: The aim of this report is to describe and discuss a unique case of acute lower limb ischemia presented in a recovered COVID-19 patient treated via percutaneous mechanical thrombectomy and catheter directed thrombolysis. Starting from this singular case a wide literature review regarding COVID-19-related thrombo-embolic complications has been accomplished. Methods: A 47-year-old male was admitted to the emergency unit with acute lower limb ischemia three weeks after testing positive for COVID-19. He had been isolated at home because of minor COVID-19-related symptoms. Angio-CT-imaging showed a segmental occlusion of the common iliac artery coupled with retro-articular popliteal artery and leg vessels thrombosis. The patient was first unsuccessfully submitted to trans-femoral iliac thrombo-embolectomy. Results: Instead of peripheral limb vessel re-thromboembolectomy, a percutaneous mechanical thrombectomy coupled with leg vessel catheter direct thrombolysis was performed. The completion angiography showed the recanalization of the popliteal artery and leg vessels as far as the ankle but with a reduced forefoot vascularization. The fibrinolytic treatment was continued for 8 hours post-operatively. A compartment syndrome complicated the early post-operative course. There was a progressive recovery of ischemic symptoms and at 6-month follow-up, peripheral pulses were palpable with an almost complete normalization of foot and toe perfusion and motility. Conclusion: Acute lower limb ischemia following COVID-19-related arterial thrombo-embolic events represents a severe complication of COVID-19 infection and may result in a high rate of revascularization failure. In these cases, Percutaneous Mechanical thrombectomy coupled with catheter directed thrombolysis might represent a less traumatic and more selective approach.
