“…EVT has been accepted as a minimally invasive procedure for SFA pseudoaneurysm. Authors had described a high long-term primary patency of EVT for SFA pseudoaneurysm, ranging from 77.1% to 100% [1–4] . Placement of a covered stent–graft has become common and is considered a treatment option for traumatic SFA pseudoaneurysm [1,3,7] .…”

“…[ 1 ] Recently, covered stenting has been applied as an alternative to open surgery (OS) to exclude pseudoaneurysm of superficial femoral artery (SFA). [ 2 , 3 ] The main advantages of endovascular treatment (EVT) are low complication rates and excellent short-term outcomes. [ 4 ] Several works have reported acceptable long-term results, with 3-year patency rates ranging from 77.1% to 100%.…”

Fracture of a covered stent–graft due to heterotopic ossification of residual hematoma after endovascular treatment of superficial femoral artery pseudoaneurysm

Rationale: Endovascular treatment (EVT) is considered a preferred procedure of superficial femoral artery (SFA) pseudoaneurysm in recent years. However, heterotopic ossification (HO) after SFA pseudoaneurysm is a rare occurrence, that may cause late stent–graft fracture. Patient concerns: A 58-year-old male who underwent EVT for SFA pseudoaneurysm 8 years ago presented with a progressive mass at the right thigh and claudication. Computed tomography angiography (CTA) showed fracture and occlusion of stent–graft, which was compressed by the deep femoral artery (DFA) pseudoaneurysm and a bone-like body. Diagnosis: According to the CTA images, the stent–graft was fractured and occluded, accompanied by DFA pseudoaneurysm. Interventions and outcomes: Debridement and arterial reconstruction were performed. Pathological analysis showed that the bone-like body was derived from HO. CTA at one-year follow-up showed that the prosthetic vessel was patent and previous hematoma disappeared. Conclusions: This report demonstrates that residual hematoma can induce HO, which may result in late stent fracture, and it should thus be removed timely. Patients with SFA pseudoaneurysm who have undergone EVT should be followed up regularly.

“…13 Another concern is the rate of occlusion of these stents, with reported incidence of up to 17%. 14 Recent technological advances involve endovascular techniques using flow-modulating stents. These stents have multiple layers specifically designed to reduce the velocity of flow in the interior of the aneurysm sac, provoking thrombosis and maintaining the flow through the principal artery and its branches.…”

Resumo Aneurismas de artérias viscerais e renais são raros (0,01 a 2%) e seu risco de ruptura varia entre os diferentes tipos e de acordo com sua anatomia e contexto do paciente (comorbidades, gravidez e histórico de transplante hepático). A mortalidade decorrente da ruptura desses aneurismas é em torno de 25%. Novas técnicas e materiais derivados da neurointervenção parecem alternativas promissoras para o tratamento desses aneurismas. Neste contexto, relatamos um caso de paciente submetida a tratamento endovascular no mesmo procedimento de aneurisma de artéria esplênica e de artéria renal com a utilização de stent Solitaire® (Medtronic, Minneapolis, EUA) e molas de liberação controlada Ruby® (Penumbra, Alameda, EUA). A paciente apresentou boa evolução com ambos aneurismas tratados de forma adequada. Em conclusão, o tratamento endovascular de aneurismas de artéria esplênica e renal no mesmo tempo operatório é exequível e demonstrou segurança e efetividade no caso relatado.

“…2,3 Traditionally surgical repair was the gold standard for these lesions but within the last decade endovascular stenting with stent-grafts has been performed effectively as an alternative. 2,4–8 Endovascular technique is the leading treatment method and surgery has become a complementary technique recently. Treatment method of injured peripheral arteries should be decided on a case-by-case basis according to local expertise.…”

Objectives To evaluate the primary patency rate at three years for the infra-aortic peripheral arterial pathologies treated with polytetrafluoroethylene-covered stent-grafts. Methods Patients treated with self-expandable polytetrafluoroethylene-covered stent-grafts for infra-aortic peripheral arterial aneurysms, pseudo-aneurysms, and arterio-venous fistulas were evaluated retrospectively. A total of 48 patients (35 male, 13 female; mean age: 53.8 ± 13.5) were included with 29.0 ± 16.5 months (median 27, range 4–70) mean follow-up period. The primary objective was to determine the primary patency rate at three years. The secondary objectives were to compare type and localization of pathology, and length and diameter of the stent-grafts with primary patency rate. Kaplan–Meier test was used as the main statistical method. Results Overall mean primary patency rate at three years was 77.10%. Polytetrafluoroethylene-covered stent-graft implantation in aneurysms had worse primary patency rate than pseudo-aneurysms and arterio-venous fistulas (66.6%, P = 0.03; 76.9%, P = 0.03; 88.2%, P = 0.01, respectively). Stent-graft location, length, and diameter are not associated with primary patency rate ( P > 0.05) but stent diameter is associated with better primary assisted and secondary patency rates ( P < 0.05). Conclusions Pathology of the lesion is associated with the long-term primary patency rate of polytetrafluoroethylene-covered stent-grafts but not the stent-graft location, length, or diameter. Stent diameter is associated with primary assisted and secondary patency rates.

ePTFE stent graft in non-steno-occlusive arterial disease: 2 centers retrospective study

Abstract: Endovascular application of Fluency stent graft seems to offer an effective, and durable less invasive alternative to standard surgical techniques for the treatment of peripheral aneurysms, pseudoaneurysms, iatrogenic arteriovenous fistulae and arterial ruptures, or penetrating injuries.
