RESUMEN
Secondary aorto-duodenal fistula (SADF) is a rare and serious event occurring in up to 45% of aortic prosthesis infections. The clinical manifestations are variable ranging from isolated signs of graft infection such as fever to massive gastrointestinal bleeding. The diagnosis is based on CT scan and is generally oriented by an inconstant association of indirect signs. Despite a high early severe postoperative morbidity and mortality, especially in presence of a preoperative shock, emergency surgery allows for the diagnosis and treatment of SADF with multidisciplinary management allowing favorable midterm outcomes among surviving patients. The images that we present in this manuscript highlight some indirect signs of SADF on CT scan that should alert clinicians to warrant on time surgical management with an illustration of per operative diagnosis of the fistula.

OBJECTIVE: The objective of this study was to evaluate the outcome of endovascular aortic arch repair for chronic dissection with a custom-made branched endograft. BACKGROUND: Acute type A aortic dissections are often treated with prosthetic replacement of the ascending aorta. During follow-up, repair of an aneurysmal evolution of the false lumen distal to the ascending prosthesis can be a challenge both for the surgeon and the patient. METHODS: We conducted a multicenter, retrospective study of consecutive patients from 14 vascular units treated with a custom-made, inner-branched device (Cook Medical, Bloomington, IN) for chronic aortic arch dissection. Rates of in-hospital mortality and stroke, technical success, early and late complications, reinterventions, and mortality during follow-up were evaluated. RESULTS: Seventy consecutive patients were treated between 2011 and 2018. All patients were considered unfit for conventional surgery. In-hospital combined mortality and stroke rate was 4% (n = 3), including 1 minor stroke, 1 major stroke causing death, and 1 death following multiorgan failure. Technical success rate was 94.3%. Twelve (17.1%) patients required early reinterventions: 8 for vascular access complication, 2 for endoleak correction, and 2 for pericardial effusion drainage. Median follow-up was 301 (138-642) days. During follow-up, 20 (29%) patients underwent secondary interventions: 9 endoleak corrections, 1 open repair for prosthetic kink, and 10 distal extensions of the graft to the thoracic or thoracoabdominal aorta. Eight patients (11%) died during follow-up because of nonaortic-related cause in 7 cases. CONCLUSIONS: Endovascular treatment of aortic arch chronic dissections with a branched endograft is associated with low mortality and stroke rates but has a high reintervention rate. Further follow-up is required to confirm the benefits of this novel approach.

OBJECTIVE: To investigate the use of cryopreserved arterial allografts (CAA) as a substitute for infected infrarenal aortic prostheses, and its outcomes. METHODS: A single centre retrospective study of consecutive patients receiving an abdominal aortic CAA after removal of an infected graft was conducted between January 1997 and December 2013. The primary outcome was the rate of allograft related revision surgery. Secondary outcomes were the 30 day mortality rate, survival, primary patency, limb salvage, and infection recurrence. Allograft ruptures secondary to infection and risk factors for allograft failure were also investigated. RESULTS: Two hundred patients (mean age 64.2 ± 9.4 years) were included. In 56 (28%) cases, infection was related to an enteric fistula. The mean follow up duration was 4.1 years. The 30 day mortality rate was 11%. Early revision surgery was needed in 59 patients (29.5%). Among them, 15 (7.5%) were allograft related and led to the death of three patients (1.5%), corresponding to a 7.5% 30 day allograft related revision surgery rate. During the first six months, 17 (8.5%) patients experienced 21 events with complete or partial rupture (pseudo-aneurysm) of the allograft responsible for five (2.5%) deaths, corresponding to a re-infection rate of 8.5%. The multivariable analysis showed that diabetes and pseudo-aneurysm of the native aorta on presentation were predictive factors for short term allograft rupture. After six months, 25 (12.5%) patients experienced long term allograft complications (rupture, n = 2, 1%; pseudo-aneurysm, n = 6, 3%; aneurysm, n = 2, 1%; thrombosis, n = 11, 5.5%; stenosis, n = 4, 2%;) requiring revision surgery resulting in one death. The five year rates of survival, allograft related revision surgery, limb salvage, primary patency, and infection recurrence were 56%, 30%, 89%, 80%, and 12%, respectively. CONCLUSION: CAAs provide acceptable results to treat aortic graft infection with few early graft related fatal complications. Long term allograft related complications are quite common but are associated with low mortality and amputation rates.

OBJECTIVE: Treatment of renal artery aneurysms (RAA) remains controversial. Endovascular treatment has increased for main trunk and for very distal aneurysms, whereas for lesions located at the bifurcation surgical treatment seems to be a valid option. The goal of this study was to describe the technique of direct reconstruction of RAA and to report on outcomes. METHODS: This study comprised single centre prospective collection of data with retrospective analysis (January 2015 to August 2018) of patients operated on for distal RAA using direct reconstruction. RESULTS: A total of 24 RAA in 21 patients (seven men and 14 women, mean age 59 ± 13 years) was included. History of hypertension was found in 15 patients and renal insufficiency was present in one. Mean pre-operative systolic and diastolic blood pressures were 134 ± 21 mmHg and 74 ± 10 mmHg, and mean pre-operative rates of creatinine and glomerular filtration rate were 67 ± 13 µmol/L and 93 ± 49 mL/min/1.73 m2, respectively. Indications for repair were a diameter >20 mm in seven cases (mean diameter = 25 ± 2 mm) or rapid growth in one case, symptomatic aneurysm in 12 cases (hypertension, haematuria, pain), and a concomitant lesion in four cases (splenic aneurysm, abdominal aortic aneurysm, occlusive visceral artery lesions). All lesions were distal, main artery bifurcation in 22 cases and hilar in two cases. The main aetiology was fibromuscular dysplasia (16 cases) followed by atherosclerosis (seven cases) and one case of Ehlers Danlos Syndrome. In situ reconstruction was possible for 22 RAA, while two cases required kidney autotransplantation. The mean renal ischaemia time was 18 ± 5 min. At two years, the patency rate was 100%, and mean systolic blood pressure decreased (134 mmHg-122 mmHg, p = .047). Renal function was stable from 93 ± 49 pre-operatively to 95 ± 35 mL/min/1.73 m2 in the post-operative course (p = .56). CONCLUSION: Direct reconstruction appears to be efficient for most RAA. This technique is complementary to ex vivo autotransplantation and endovascular treatment.

We report the case of a young man who developed a lower limb claudication associated to a lower limb discrepancy secondary to a closed traumatism during childhood that had never been explored. Fifteen years later, we managed to get the young man get rid of his crippling claudication, but it was unfortunately too late to correct the lower limb asymmetry.

BACKGROUND: Soft tissue malignancy of lower limb can involve femoral triangle by direct tumoral invasion or secondary to ganglionic metastasis. Secondary arterial complications can appear during follow-up after initial tumoral resection and local radiation therapy. The aim of this study is to report our experience of secondary extra-anatomical lower limb revascularization following lower limb oncological resection with femoral bifurcation involvement. METHODS: This is a retrospective monocentric study including patients who underwent extra-anatomical iliopopliteal bypass, with a previous treated neoplasia involving homolateral femoral bifurcation. Proximal anastomosis was performed on the iliac artery, tunnelization was made through iliac wing, and distal anastomosis was done on distal superficial femoral or popliteal artery. RESULTS: Five patients underwent extra-anatomic iliopopliteal bypass for oncological purpose from 2008 to 2018 at our institution. Mean age at surgery time was 52 years (standard deviation = 19.3). Prosthetic graft was used in all cases. Primitive tumor involved Scarpa triangle in 3 cases (soft tissue sarcomas) and ganglionic metastasis involved Scarpa triangle in 2 cases (epidermoid carcinoma). Clinical presentation was ischemic in 4 cases and hemorrhagic in 1 case. One patient died during hospitalization. Of the 4 survivors, 3 patients had a patent bypass at the end of follow-up (2 had bypass thrombectomy, 1 patient had major amputation). CONCLUSIONS: Secondary iliopopliteal bypasses through the iliac wing following lower limb tumoral resection have acceptable results. It is a valid option for limb salvage especially after local radiation therapy and tumoral resection. Multidisciplinary management is necessary to obtain acceptable results and follow-up is mandatory.

BACKGROUND: The objective of the study was to evaluate the feasibility and early outcomes of complex aortic aneurysm repair in high-risk patients with hostile anatomies using both parallel stents and physician-modified stent graft (PMSG) techniques to address the renovisceral arteries. METHODS: Consecutive patients with complex suprarenal (SRA) and thoracoabdominal aortic aneurysms (TAAAs) undergoing endovascular repair using combined parallel stents technique and PMSG between September 2013 and November 2015 were evaluated. All patients required prompt aneurysm treatment. Fenestrations to preserve branch vessels were created in thoracic stent grafts. Depending on the anatomy, chimney or snorkel stents were deployed in renal or visceral arteries as complementary technique to overcome severe angulations or preexisting suprarenal stent. Preoperative, intraoperative, and postoperative data were recorded by means of a prospectively maintained database. RESULTS: Six high-risk patients with TAAA (type I: n = 2, type III: n = 1) and SRA (n = 3) underwent endovascular repair using both parallel stents technique and PMSG. Indications were painful aneurysms (n = 1) and >70-mm rapidly enlarging aneurysms (n = 5). Ten thoracic components were used, of which 6 were modified intraoperatively. Twenty-one renovisceral arteries were revascularized, using dedicated fenestrations (n = 10, 47.7%), chimney (n = 7, 33.3%), and snorkel stents (n = 4, 19%). The mean operative time was 326 ± 82 min including the device modification time. The mean time for graft modification was 90 ± 15 min. In 1 patient, a rescue chimney stent intended to the superior mesenteric artery was deployed because of failed cannulation through the dedicated fenestration. Technical success rate was 83.3%. One patient died during the early postoperative course from severe stroke. Among surviving patients, 3 required early reinterventions for iliac occluder-related type II endoleak (n = 1), type Ia endoleak (n = 1), and gastroduodenal artery embolization (n = 1). The mean follow-up was 14.2 ± 4.8 months. One early gutter-related type I endoleak resolved during follow-up. No other complications occurred, and all target vessels remained patent. CONCLUSIONS: PMSG combined with parallel stent provided acceptable short-term results in specific presentation of SRA and TAAA with hostile anatomies in selected high-risk patients with contraindication for standard fenestrated/branched grafts. More reliable outcomes require larger population and follow-up.

BACKGROUND: Cryopreserved arterial allografts are vascular substitutes used for arterial reconstructions in a septic field. Their use remains however limited by the shortage of donors. One of the possibilities to address this lack of grafts is to multiply the sources of retrieval. The objective of this preliminary study was the evaluation of the early clinical results and the microbiological safety of arterial grafts retrieved after death. METHODS: In addition to the standard conditions of arterial sampling, the criteria of inclusion for postmortem retrieval comprised the refrigeration of the body of the donor within 4 hr following the death, a 24-hr time limit from the death, and the availability of an adapted place for retrieval (surgical unit or death chamber respecting the required aseptic conditions). We only retrieved the femoral axes (FAs) and the aortoiliac bifurcation. The conditions of retrieval, transportation, preparation, and conservation were identical to those of cryopreserved arterial allografts harvested during standard multiple organs retrieval. We evaluated the bacteriological risk of contamination and the patency of the grafts in the short and medium term. RESULTS: In 2015 and 2016, 6 donors were included. Eleven FAs and 2 aortic bifurcations were harvested. The bacteriological samples done on arrival in bank and after thawing were negative in the 6 donors, but one of the 6 donors presented a bacterial contamination of other removed tissues, and the arterial grafts obtained from this donor were destroyed as a precaution (3 grafts). The quality of the grafts evaluated by the surgeon during harvesting was good in all the cases. The indications of allografts were arterial reconstruction in a septic field (n = 8) and aorto-hepatic bypass during hepatic transplantation (n = 1). One graft was unhopefully thawed without being used. At the end of the follow-up, 8 out of 9 grafts were patent. Two ruptures occurred in a context of locally persistent sepsis (crural abscess due to Salmonella typhi and persistent groin wound disunion with a polymicrobial flora). One allograft thrombosis was observed (aorto-hepatic bypass for transplantation). These complications were unrelated to the mode of graft harvesting. No aneurysmal evolution was observed. CONCLUSIONS: The preliminary results of this protocol are encouraging because the immediate quality of the grafts was good with a risk of microbiological contamination identical with that of the usual harvesting mode. This mode of harvesting looks promising to reduce the shortage in arterial allografts and could be extended to harvest thoracic aortic allografts. However, results at a larger scale are necessary to confirm these data.

Traumatic injury of the left common carotid is a rare but severe disease, and is an uncommon situation in emergency units. Thoracic aortic lesions are often associated with other injuries, making their treatment challenging. We report the case of a successful hybrid approach to treat this lesion using a total supra aortic vessel debranching and a thoracic endovascular graft to cover the rupture, in a 38-year-old polytraumatized patient. After aortic, abdominal, and orthopedic surgery, the patient recovered well. The 1-year follow-up showed a good result of this hybrid treatment. This technique should be considered in polytraumatized patients with aortic arch lesions.

Fibromuscular dysplasia (FMD) is known as rare cause ischemic stroke and usually involves the internal carotid or vertebral arteries in middle age women. A poorly known type of FMD located at the carotid bulb is called atypical fibromuscular dysplasia. We present the case of 3 young black patients suffering from recurrent ischemic strokes in the same middle cerebral artery territory. Computed tomographic angiography and arteriography showed a moderate diaphragmatic stenosis of the carotid bulb. After surgical removal of the dysplasia, postoperative course was uneventful without any recurrence. Pathologic examination confirmed atypical FMD. Carotid-bulb atypical FMD is a rare cause of stroke and concerns mostly young black patients. Surgical approach should be recommended to avoid recurrent stroke.

Objective: The treatment of complex aortic disease has been described with various retrograde visceral bypass techniques. An original technique with a single stem retrograde visceral graft (SSRVG) is presented. Methods: This was a single centre retrospective study including 16 patients between 2015 and 2019. Patients were treated for aortic dissection (AD; type A and acute or chronic type B), thoraco-abdominal aortic aneurysms (TAAAs), and visceral occlusive disease. Surgery consisted of visceral vessel debranching from the native infrarenal aorta or from an aortic graft. In the case of AD, surgical fenestration was performed. Additional thoracic endovascular aneurysm repair (TEVAR) completed the treatment when indicated, during the same procedure or later. Patient outcomes and reconstruction patency were studied. Results: The mean patient age was 64 years (median 68 ± 12.6). Ten (62%) patients were treated for AD, three (19%) for TAAA, and three (19%) for occlusive disease. Sixty-nine target vessels were debranched with this SSRVG technique. Aortic surgical fenestration was performed in eight cases and TEVAR in four. During their hospital stay, three (19%) TAAA patients died, seven cases of renal insufficiency (44%), four cases of pneumonia (25%), and three colonic ischaemia cases (19%) were noted. After a mean follow up of 21 months, no other deaths occurred. All vessels (except two inferior mesenteric arteries) were patent and no endoleak was noted. Conclusion: The SSRVG technique can be offered in various complex aortic diseases. The use of a single graft is feasible and reduces the volume of multiple branch assembly in the retroperitoneal space. The observed patency rate is high.

Aorto-cutaneous fistula and false aneurysm of the ascending aorta in patients who previously underwent Stanford Type A acute aortic dissection are rare and severe complications. Surgical correction remains a demanding challenge. In a case of false aneurysm rupture during redo sternotomy, selective cannulation of the right axillary and left carotid arteries allowed an efficient method of cerebral perfusion.
RESUMEN
We report 4 cases of off-pump ascending aorta wrapping combined with ascending aorta stenting in retrograde Stanford A acute aortic dissection (SAAD). Since 2008, 18 patients have undergone wrapping of the ascending aorta at our institution. Four patients had a persistent circulating false lumen in the ascending aorta after wrapping, with a threat to the aortic root. We chose an endovascular approach with ascending aorta stenting. Follow-up computed tomography showed a reapplication of the intimal flap in the reinforced aorta. Ascending aorta stenting after aortic wrapping for retrograde SAAD is a safe and efficient technique to prevent proximal progression of the dissection.
