Among the complications related to the endovascular treatment of the left common iliac vein obstruction, the contralateral deep venous thrombosis consists in a late complication of the procedure. This case series describes the endovascular treatment of four patients with right iliofemoral deep venous thrombosis caused by jailing of the inferior vena cava confluence, due to previous stents implanted in the left common iliac vein. All the four patients were admitted with pain and swelling of the right lower limb, and one patient presented with phlegmasia cerúlea dolens. The patients were evaluated with duplex-scan and angioCT-Scan that confirmed extensive right iliofemoral and femoropopliteal deep venous thrombosis, except for one patient, whose DVT propagated to superficial femoral vein, without popliteal involvement. All patients were submitted to endovascular treatment with pharmacomechanical thrombectomy, previous stent recanalization and stent deployment in the iliocaval confluency. Regarding the post-operative complications, one patient presented with hemoglobinury, which evolved with anuria, and in the first day post-operative with acute kidney failure and necessity of hemodialysis for 8 days, after that evolved with total renal function recovery. During the hemodialysis period, this patient received non-fractioned heparin, instead of enoxaparin. All patients presented with satisfactory improvement on limb edema, in the first day and thereafter in the first week post-operative. The pharmacomechanical thrombectomy technique followed by angioplasty and kissing stenting was a safe and efficient procedure in this case series report.
A case of a woman with cleidocranial dysostosis resulting in upper right limb ischemia is presented. This uncommon condition is an exceedingly rare cause of vascular compression that gives rise to thrombosis of the axillary-subclavian arteries. Only two cases have previously been reported.
Objetivos. Relatar un caso de revascularización de vena cava inferior debido a una trombosis como consecuencia del uso de filtro, investigar en la literatura el número de casos y comparar el diagnóstico y los tratamientos. Resultados. Los trabajos de la literatura describen la colocación de un único stent cubriendo el filtro y kissing stents, con buenas tasas de permeabilidad con el uso de anticoagulación aislada, siendo seguros y eficaces en el seguimiento a mediano plazo, con una mínima morbilidad y tasas de reintervenciones bajas, pero con pocos casos en cada estudio. Conclusión. La recanalización de la vena cava inferior debido a la trombosis de filtro se puede realizar con la colocación de kissing stents, incluso con pacientes trombofílicos, con buena tasa de permeabilidad a mediano plazo.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
