A Hybrid Approach That May Facilitate the Repair of Traumatic Popliteal Artery Pseudoaneurysms.

PURPOSE: Traumatic popliteal pseudoaneurysms may occur in accidents or as an iatrogenic complication of a total knee arthroplasty. Complications often arise in open repair because of distorted anatomy. Up to 22% of the patients may suffer above-knee amputation. Endovascular treatment has proven to be an effective solution. However, the long-term performance of stents at the hinge point of the popliteal artery is questionable. We present a hybrid technique that was used successfully in 2 cases. TECHNIQUE: Our approach takes advantage of both open and endovascular techniques. At first, we apply a stent graft at the side of the injury to cover the arterial trauma and stop blood leakage to the aneurysm sac. This allows for a safer dissection and open repair. We clamp the artery proximally and distally, open the sac, extract the stent graft, and extend to a longitudinal arteriotomy. We then reconstruct the entire area with a standard in lay end-to-end anastomosis using a vein graft. This hybrid technique may reduce the risk of uncontrollable bleeding and allow for a safer nerve decompression. CONCLUSIONS: Repair of such injuries is technically demanding. A hybrid approach may reduce the risk of complications and offer excellent long-term outcomes. CLINICAL IMPACT: The hybrid approach to the treatment of traumatic popliteal pseudoaneurysms combines the advantages of both open and endovascular approaches. It may be possible to make an acute operation just as safe as an elective operation by implementing the proposed strategy. The procedure can be performed by surgeons of all levels, and patients may benefit from a safer surgical dissection with fewer complications and blood loss. This smart combination of standard techniques may prove invaluable in a hostile surgical environment where limb loss is likely.

Conservative treatment vs thrombus removal for Iliofemoral vein thrombosis in patients with congenital abnormalities of the inferior vena cava: a case report and systematic review of the literature.

Congenital abnormalities of the Inferior Vena Cava (IVC) should be suspected in cases of Deep Venous Thrombosis (DVT), especially in young patients, with no other risk factors and apparent causes. Currently, there is no guidance regarding the management of such patients. We report a case of Iliofemoral vein thrombosis in a young patient with congenital absence of the IVC that was successfully treated with catheter-directed thrombolysis (CDT) and perform a systematic review of the literature to identify evidence about the epidemiology, clinical presentation, management, and prognosis of this rare cause of DVT. A total of 42 studies reporting on 56 cases were included in the review. The mean age of the patients at the presentation of their first DVT episode is 23.6 years, 83.9% of patients were males, conservative management with anticoagulation was used in 68% of the reported cases, and thrombolysis was used in 32% of the cases. Only 10.7% of patients presented with PE potentially justified by the abnormal anatomy of the deep veins which makes the propagation of thrombi into the pulmonary arteries less possible. Comparing the long-term outcomes of the two treatment groups; 42.3% of the patients treated conservatively vs 15.4% of the patients treated with thrombolysis developed chronic symptoms (residual heaviness, pain, swelling, and cramping). 11.5% of patients who received conservative treatment developed post-thrombotic syndrome. None of the patients treated with thrombolysis developed post-thrombotic syndrome. There were no procedure-related complications and thrombolysis was well tolerated by the entirety of the thrombolysis treatment group. Recurrence of DVT occurred in 13% of the patients treated conservatively and in 7.7% of patients treated with thrombolysis. Thrombus removal by means of thrombolysis is the recommended treatment and can offer excellent short and long-term results. Anticoagulation with NOACs may be prescribed for life to prevent recurrence or for at least 6 months and then reconsidered following further evaluation of patients' bleeding risk. It may be of value to organise an international registry for such patients. Guidelines issued by the relevant scientific societies will then be able to make a clear recommendation about the management of such patients.

EndoVenous-assisted invaginated stripping of the great saphenous vein: A pilot and feasibility study.

Objective: By incorporating an endovascular component into Great Saphenous Vein stripping, EndoVenous-assisted Invaginated Stripping (EVIS) aims to make the procedure minimally invasive. A study was conducted to investigate the surgical intervention. Methods: Sketches and videos were used to illustrate the technical aspects of EVIS. A prospective cohort study included 20 patients with chronic venous insufficiency (CVI). Results: EVIS is performed as a day-surgery. Technical success was 100%, and no complications were recorded. The mean operative time was 45 minutes, intraoperative pain score was 4.8, post-operative pain was 2.5, 1.8, 1.2, 0.5 at 48 hours, 1, 4, and 12 weeks, respectively. The mean blood loss was 15 mL, and the mean length of the GSV strapped was 19 cm. The follow-up duplex showed a reduction in the diameter of the residual GSV stump. Conclusions: EVIS is a combination of standard techniques that may prove valuable in managing CVI.
