Papel del cirujano vascular en la fijación anterior de columna / Role of the vascular surgeon in anterior spine fixation

La fijación anterior de columna es una técnica bien implantada en la cirugía espinal. La presencia y necesidad de manipular los vasos principales, la aorta y las ilíacas y el riesgo hemorrágico que ello presenta hacen recomendable la colaboración de un cirujano vascular como cirujano de abordaje durante los procedimientos. Presentamos la experiencia de nuestro hospital en el tratamiento de fijación anterior de columna entre los servicios de traumatología y de cirugía vascular con una serie de 28 casos comprendidos entre el 2017 y el 2021.(AU)

Anterior spinal fixation is a well-established technique in spinal surgery: The presence and need for manipulation of the main vessels, aorta and iliac, and the risk of bleeding that presents, makes it advisable to have a Vascular Surgeon as an approach surgeon during the procedures. We present the experience of our Hospital in the treatment of anterior fixation of the experience of our Hospital in the treatment of anterior of the spine with the traumatology and vascular surgery service with a series of 28 cases between 2017 and 2021.(AU)

Fatal vascular complication due to metallosis.

Metallosis is a well-known complication at the site of total hip and knee arthroplasty. Vascular involvement of this complication is rare and generally results from vascular compression by a mass or pseudotumor. In the present report, we have described a case of lower limb acute arterial ischemia due to arterial injury as a complication of metallosis with a fatal outcome.

Usefulness of aneurysm sac angiography in therapeutic management of an endoleak after endovascular aneurysm repair.

Endoleak treatment after endovascular aneurysm repair (EVAR) can be difficult and complex. The key to success lies mostly in the accurate interpretation of imaging tests. We describe the case of a patient who was urgently operated on due to an episode of acute arterial ischemia in the left lower limb for stent-graft iliac limb thrombosis and a proximal type I endoleak. We highlight the importance of performing aneurysm sac angiography as part of an effective therapeutic strategy.

Duplex mapping of 2036 primary varicose veins.

OBJECTIVE: To produce a comprehensive anatomical and hemodynamic ultrasound scan mapping of the whole limb in patients with primary varicose veins (VVs). DESIGN: An analysis of venous duplex scans performed on patients referred for treatment of primary VVs. METHODS: A total of 2036 limbs were evaluated, looking for the origin of VVs in the saphenous systems and in the perforating vein (PV) systems, as well as for the presence of non-saphenous reflux. RESULTS: The sapheno-femoral junction (SFJ) of the great saphenous vein (GSV) was involved in 1330 limbs (65.3%). We have noted that finding reflux in the groin does not imply that it originates at that point necessarily, as reflux from the pelvis or abdominal wall can also cause primary VVs (SFJ reflux, 41.9% and competent SFJ with reflux from proximal veins, 35.4%). We also noted that analyzing only the presence of reflux in the SFJ of the GSV would miss 10.9% of limbs of reflux in the SFJ of the anterior accessory GSV. In 237 limbs (11.6%), reflux was observed in the popliteal fossa. In the PV system, we distinguished those PVs with retrograde flow that acted as an origin of the VVs, and other PVs that acted as re-entry points. Based on this difference, the location identified as the most frequent origin of VVs in the PV system was the thigh, specifically in the group of PVs of the medial thigh of the femoral canal, with 85 PVs with a total of 238 incompetent PVs identified. Pure non-saphenous reflux was observed in 162 limbs (8%). CONCLUSION: The assumption that the origin of VVs would be exclusively in the sapheno-femoral or sapheno-popliteal junction, is a mistaken attitude and a comprehensive duplex scan mapping is recommended.
