RESUMEN
Background: Size matching between donors and recipients is a major issue in lung transplantation (LTx), especially in patients with restrictive lung disease (RLD). This study aims to evaluate computed tomography (CT) as an additional method for defining the total lung capacity (TLC) in patients with end-stage interstitial disease awaiting LTx. Methods: Clinical data and CT scans from patients who underwent a first LTx from January 2014 to July 2018 in Bichat Hospital, Paris, were prospectively included in a database. CT TLC (ctTLC) was retrospectively calculated after semi-automatic contouring of the parenchyma and compared with measured TLC (mTLC) and predicted TLC (pTLC) values. Results: The study group included 89 patients (male:female =68:21; mean age, 59.5±10.0 years). The time between pulmonary function tests (PFTs) and CT scan was 162±270 days [median, 67 days; interquartile range (IQR), 0-233 days]. ctTLC was inferior to mTLC and pTLC (respectively 2,979±1,001 mL, 3,530±1,077 and 6,381±955 mL, P<0.001). The relative difference between CT lung volume (ctLV) and measured lung volume (mLV) was higher on the left than on the right side (25.4% vs. 16.3%, respectively, P=0.11). After exclusion of two outliers, we found a significant correlation between ctTLC and mTLC (r=0.762, P<0.001). Conclusions: CT volume is a feasible method to assess TLC in patients with end-stage interstitial disease awaiting LTx. This study highlights potential size-mismatch for graft selection before LTx and opens the perspective of a prospective trial evaluating impact of size-matching by donor-recipient (D-R) ctTLC ratio on postoperative outcomes.

For symptomatic buttock arteriovenous malformations (AVMs), embolization techniques and surgical resection have been suggested as treatment options. Our aim was to evaluate the feasibility and long-term results after a single surgical resection. Twelve patients had undergone surgical resection without preoperative embolization. Of the 12 patients, 11 had had incomplete procedures, 9 of whom had undergone arterial embolization 1 to 3 years previously. All the patients were symptomatic. Computed tomography scans showed AVMs located in the cellular spaces with preservation of the gluteal muscle. The median follow-up time was 80 months. On the last follow-up computed tomography scan, 67% had had no residual AVM. The use of preoperative embolization, especially with nonresorbable embolic material (Onyx; Medtronic, Dublin, Ireland), makes AVM resection and imaging follow-up more difficult because of artifacts and should be avoided.
RESUMEN
BACKGROUND: COVID-19 infection is associated not only with venous thromboses but also with arterial thromboses (COV-ATs) in relation with an endothelial dysfunction, a coagulopathy and rhythm disorders. The incidence, the topography, and the prognosis of COV-ATs remain poorly known. The objective of this study was to report the overall experience of the Greater Paris University Hospitals (Assistance Publique - Hopitaux de Paris, AP-HP) during the first pandemic wave of COVID-19 infection. METHODS: After approval by the ethics committee, a study using the AP-HP clinical data warehouse was carried out between March and May 2020. Overall, 124,609 patients had a polymerase chain reaction for COVID-19 in our hospitals, of which 25,345 were positive. From 20,710 exploitable stays, patients tested positive for COVID who presented an episode of acute COV-AT (except coronary and intracranial arteries) were selected on the basis of the French medical classification for clinical procedures codes. The data are presented as absolute values with percentages and/or means with standard deviation. RESULTS: Over the studied period, 60 patients (aged 71±14 years, 42 men) presented a COV-AT at the time of their hospitalization, an incidence of 0.2%. The arterial complication occurred 3±7 days after the COVID infection and was inaugural in 30% of the cases (n = 18). The sites of COV-AT were the lower extremities (n = 35%, 58%), the abdominal aorta (n = 10%, 17%), the thoracic aorta (n = 7%, 12%), the upper limbs (n = 7%, 12%), the cerebral arteries (n = 7%, 12%), the digestive arteries (n = 6%, 10%), the renal arteries (n = 2%, 3%), and the ophthalmic artery (n = 1%, 2%). Multiple COV-ATs were observed in 13 patients (22%). At the time of diagnosis, 20 (33%) patients were in intensive care, including six (10%) patients who were intubated. On computed tomography angiography, COVID lesions were classified as moderate and severe in 25 (42%) and 21 (35%) cases, respectively. Revascularization was attempted in 27 patients (45%), by open surgery in 16 cases, using endovascular techniques in 8 cases and with a hybrid approach in three cases. Six patients (22%) required reinterventions. The duration of hospitalization was 12±9 days. Early mortality (in-hospital or at 30 days) was 30% (n = 18). Nine (15%) patients presented severe nonlethal ischemic complications. CONCLUSIONS: Arterial involvement is rare during COVID-19 infection. The aorta and the arteries of the limbs are the privileged sites. The morbi-mortality of these patients is high. Future studies will have to determine if the systematization of anticoagulation therapy decreases the incidence and the severity of the condition.

Background: In Marfan syndrome (MFS), an aortic or peripheral arterial dilatation is usually the consequence of aortic dissection. Non-dissecting distal aortic and peripheral aneurysms (DAPA) are barely described. We sought to determine the incidence and prognostic impact of non-dissecting DAPA, requiring a surgical repair in a large population of patients with MFS. Methods: The patients referred to the French MFS reference center were included in a prospective database, and the patients treated for a non-dissecting DAPA between 2013 and 2020 were retrospectively reviewed. The first-line therapy was open surgery. The patients unfit for open repair or experiencing life-threatening complications underwent endovascular repair. Results: Among 1,575 patients with MFS, 19 (1.2%) were operated for 25 non-dissecting DAPA. The mean age was 42.4 ± 11.5 years. Non-dissecting DAPA involved the subclavian or axillary artery (n = 12), the descending or thoracoabdominal aorta (n = 6), the abdominal aorta andiliac arteries (n = 6), and the popliteal artery (n = 1). Open and endovascular repairs were performed in 22 and three cases, respectively. After a median follow-up of 54.2 months, no local recurrence was noticed and no secondary procedure was performed. Eight patients presented a new aortic event, including two aortic dissections and seven new aortic surgeries. Compared to the overall MFS population, the non-dissecting DAPA group presented a significantly higher risk of an aortic event (100 vs. 28%, p < 0.0001), a higher risk of aortic dissection (53 vs. 8%, p < 0.0001), and a higher rate of pejorative genetic mutations (68 vs. 40%, p = 0.011). Conclusion: Among the patients with MFS, the diagnosis of non-dissecting DAPA is infrequent but is associated with a significant adverse outcome, thus, advocating for a specific follow-up.
RESUMEN
We retrospectively reviewed 35 patients with venous malformations located in the forearm and treated by surgery in a single institution during the period 2010-19. The common complaints were pain and swelling (34 patients) and impaired function with contractures of fingers (15 patients). Twenty-four had complete resection and 11 had an incomplete resection. Associated procedures were reconstruction or lengthening of tendons in 17 patients. At the last follow-up (mean 61 months), 32 of the 35 had no residual pain and 27 had no functional sequelae. On MRI follow-up exams, 27 had no residual venous malformations. Venous malformations in the anterior compartment of the forearm can impair the function of the hand. They are developed almost exclusively in the connective tissue around tendons and muscles, deforming the musculotendinous structures and involving nerves. Surgery seems an appropriate option for the condition in this area.Level of evidence: IV.

OBJECTIVE: To report the intra-operative adverse events (IOAEs) and the initial and one year outcomes of retrograde open mesenteric stenting (ROMS) using balloon expandable covered stents for acute and chronic mesenteric ischaemia. METHODS: Clinical data and outcomes of all consecutive patients treated with ROMS for acute and chronic mesenteric ischaemia at an intestinal stroke centre between November 2012 and September 2019 were reviewed. ROMS was performed using balloon expandable covered stents. Endpoints included IOAEs, in hospital mortality, post-operative complications, and re-interventions. One year overall survival, freedom from re-intervention, primary patency and assisted primary patency rates were analysed using the Kaplan-Meier time to event method. RESULTS: During the study period, 379 patients were referred to the centre for acute or chronic mesenteric ischaemia. Thirty-seven patients who underwent the ROMS procedure were included. All the patients had severe atherosclerotic mesenteric lesions. The ROMS technical success rate was 89% in this cohort. The rate of IOAEs was 19% and included four cases of retrograde recanalisation failure. All ROMS failures occurred in patients presenting with flush superior mesenteric artery occlusion and they were treated by mesenteric bypass. Ten patients (27%) underwent bowel resection, four of which resulted in a short bowel syndrome (11%). The in hospital mortality rate was 27%. Post-operative complications and re-intervention rates were 67% (n = 25) and 32% (n = 12), respectively. The median follow up was 20.2 months (interquartile range 29). The estimated one year overall survival for the cohort was 70.1% (95% confidence interval [CI] 52.5% - 82.2%). The estimated freedom from re-intervention at one year was 61.1% (95% CI 42.3 - 75.4). The one year primary patency and assisted primary patency rates were 84.54% (95% CI 63.34 - 94) and 92.4% (95% CI 72.8 - 98), respectively. CONCLUSION: ROMS procedures offer acceptable one year outcomes for mesenteric ischaemia but are associated with frequent stent related complications. Precise pre-operative planning, high quality imaging, and meticulous stent placement techniques may limit the occurrence of such events.

OBJECTIVE: Despite the continuing controversy of covered stents (CS) vs bare metal stents, the use of CS in mesenteric occlusive disease (MOD) has been recommended by expert centers. The aim of this study was to report midterm results with CS of the superior mesenteric artery. METHODS: Between January 2014 and October 2019, patients with MOD with a severe atheromatous stenosis or occlusion of the superior mesenteric artery treated by mesenteric CS were included. Clinical presentation included both acute mesenteric ischemia (AMI), chronic mesenteric ischemia, and asymptomatic patients planned for major surgery. Demographics, procedure details, and follow-up data were prospectively collected and retrospectively reviewed. Study end points included primary patency, primary assisted patency, and secondary patency. RESULTS: During the study period, 86 patients (mean age, 70 ± 9 years; 57% males) were included. Clinical presentation was AMI (n = 42 [49%]), chronic mesenteric ischemia (n = 31 [36%]), and asymptomatic (n = 13 [15%]). The technical success rate was 97%. A total of 96 stents were implanted, including 86 proximal CS (Advanta V12, n = 73; Lifestream, n = 13). The mean length and mean diameter of the CS were 31.5 ± 6.3 mm and 6.9 ± 0.5 mm, respectively. Additional distal bare metal stents were used in 10 patients (12%) to overcome a kinking (n = 9) or a dissection (n = 1) downstream of the CS. All postoperative deaths occurred in patients with AMI (n = 11, 13%). During a median follow-up of 15.6 months (95% confidence interval [CI], 15.6 ± 3.6 months), 12 patients (14%) underwent reinterventions for either stent misplacement (n = 3), stent recoil (n = 3), stent thrombosis (n = 2), de novo stenosis at the distal edge of the CS (n = 2), or gastric ischemia (n = 1). At 1 year, overall the primary patency, primary assisted patency, and secondary patency rates were 83% (95% CI, 83% ± 9%), 99% (95% CI, 99% ± 3%), and 99% (95% CI, 99% ± 3%), respectively. At 2 years, the overall primary patency, primary assisted patency, and secondary patency rates were 76% (95% CI, 76% ± 13%), 95% (95% CI, 95% ± 8%) and 95% (95% CI, 95% ± 8%), respectively. CONCLUSIONS: Mesenteric CS provide very satisfactory midterm results in patients with MOD, with an excellent primary assisted patency rate at 2 years, at the price of a significant reintervention rate.

We report 8-year experience with vascular access complications (VACs) after percutaneous transfemoral transcatheter aortic valve implantation (TAVI). From January 2010 to January 2018, patients with iliofemoral VAC treated by an intervention following percutaneous transfemoral TAVI were included. Major VAC was defined according to the Valve Academic Research Consortium 2 classification. As first-line strategy, VACs were treated using covered nitinol stents (CS). Among 795 percutaneous transfemoral TAVI, 74 (9.3%) patients (female, 57%; 82 ± 8 years) with VAC treated by CS and/or open repair were included in this study: 59 CS cases and 15 open repair cases. Two CS patients were converted to open repair. Technical success for stent implantation was 97%. The main VAC was a persistent bleeding related to percutaneous closure device failure (72%). Thirty-day mortality in the study cohort was 5.4% (4/74), including 1 VAC-related death. One patient had postoperative lower limb ischemia successfully treated by open repair. No amputation, new-onset claudication or in-stent occlusion was recorded. Endovascular intervention using self-expandable nitinol covered stent is safe and effective as a first-line strategy for the treatment of VAC in percutaneous transfemoral TAVI. However, open repair is needed in case of unfeasibility or failure of endovascular therapy.

The study of vascular anomalies, "angiomas", vascular tumours and vascular malformations is made difficult by the great variety and confusion of the names used in the literature for these diseases, some of which are rare. The great merit of the classification proposed by the International Society for the Study of Vascular Anomalies (ISSVA), adopted in 2014 and modified in 2018, is to propose a unambiguous nomenclature and to try to group these lesions in a logical way, contrasting with the lists of the usual "classifications". This classification is based on the distinction between proliferative lesions (tumours and reactive lesions) and those which are due to a congenital anomaly of vascular morphogenesis (vascular malformations). It incorporates recent data on the molecular causes of these diseases. The major groups of lesions recognised in this classification will be presented and some lesions of interest briefly discussed. This classification aims to be usable by all medical specialties and applicable to all tissues and organs, even if efforts are still needed to integrate organ-specific names in order to unify the nomenclature and eliminate confusion. Even if it does not solve all the problems in this complex field, the unification of the nomenclature is a major contribution of this classification and pathologists are strongly encouraged to refer to it in daily practice.

BACKGROUND: Our aim was to evaluate the benefit of surgical resection of the venous malformations (VMs) of the external female genitalia. METHODS: Over the period of 2009-2019, 18 consecutive females underwent surgical resection for vulvar VM. Evaluations included preoperative Doppler ultrasound, MRI, and pre-and postoperative photographic imaging. The main outcomes were: residual pain, cosmetic distortion, residual VM, and quality of life. RESULTS: Over a 10 year periods, 18 females, mean age 35 years (range 9-71) were included in this study. All patients were symptomatic: 16 had intermittent pain or discomfort, 1 had bleeding and 2 requested cosmetic treatment. Of these cases, there were 5 isolated vulvar VM, 12 associated VM: 3 of the clitoral hood, 3 troncular pelvic vein insufficiency and 12 of the lower limb. Eight patients had undergone previous procedures: 2 sclerotherapy treatments (1-3 sessions), 4 partial surgical resections. There were 18 single resections in the vulva (7 focal, 11 complete), 2 partial resections in clitoral hood and 2 had resection of a VM in the perirtoneovaginal canal at the same time. The mean follow-up was 42. 9 months (range 6-120). Two patients were lost to followup at 6 months. For all patients, elimination of pain and soft tissue redundancy was achieved. Two patients had persistent discomfort and 2 requested cosmetic treatment. CONCLUSION: Surgical resection of vulvar VM can be the best approach with few postoperative complications, good functional and cosmetic results. Appropriate preoperative evaluation is required to identify isolated VM or VM associated with ovarian vein or internal iliac vein insufficiency requiring to be treated before surgery.

BACKGROUND: Open repair of type II thoracoabdominal aortic aneurysms (TAAAs) remains a challenging procedure. Staged procedures could decrease the incidence and severity of complications after complex aortic repair. In the present report, we have described a strategy using thoracic endovascular aortic repair (TEVAR) for proximal repair, followed by distal open repair. METHODS: From 2014 to 2018, 14 patients had undergone TEVAR, followed by distal open repair, for type II TAAAs. All patients should have a suitable proximal landing zone according to the current guidelines. In cases of chronic dissection, false lumen embolization was performed to achieve total exclusion. RESULTS: The mean patient age was 48 ± 15 years. Of the 14 patients, 5 had had Marfan syndrome (36%) and 6 had undergone previous aortic arch repair (43%). Ten patients had had a chronic dissection. The maximal aortic diameter was 73 ± 12 mm. The TEVAR technical success rate was 100%. The aortic length coverage was 211 ± 63 mm. The number of covered segmental arteries was 6 (range, 4-13). Two endoleaks were observed, one type Ib and one type II. The delay between TEVAR and open repair was 12 ± 8 weeks. Cerebrospinal fluid drainage was used in 13 patients. Six patients had undergone segmental artery reattachment during surgery. No spinal cord ischemic event was observed. One patient had died 5 weeks after open repair of multiple organ failure. During the 32 months of follow-up, no aortic-related deaths had occurred. No new aortic procedure was needed. The type Ib endoleak had resolved during open repair, and the type II TAAA had resolved spontaneously. The mean maximal thoracic aortic diameter had significantly decreased to 49 ± 8 mm (P < .0001). Aneurysmal shrinkage of ≥5 mm was observed in 13 patients (93%). CONCLUSIONS: Staged hybrid repair of type II TAAAs appears to be efficient, with low morbidity and mortality rates. This technique could improve postoperative outcomes after open repair, and TEVAR might have a role in ischemic preconditioning to protect against spinal cord ischemia.

BACKGROUND: The outcome of lung transplantation (LT) is correlated with donor selection. A donor age of 65 years is classically considered a contraindication to lung procurement, and the results of LT from elderly donors remain to be established. METHODS: This was a retrospective study of a prospectively maintained database including all LTs performed in a single institution (Bichat Hospital, University of Paris, Paris, France) from January 2014 to March 2019. Donors65 years of age or older were included in the elderly group, whereas donors younger than 65 years of age were included in the control group. RESULTS: The study group included 241 LTs, including 44 (18%) in the elderly group and 197 (82%) in the control group. As compared with the control group, the elderly group was characterized by the following: donors of shorter stature (166 cm vs 172 cm; P = .04) and with less smoking history (14% vs 40%; P = .001), less bronchoscopic abnormality (20% vs 36%; P = .042), and less chest opacity (16% vs 30%; P = .048); and recipients of shorter stature (166 cm vs 170 cm; P = .04) but with similar diagnoses and gravity. There was no significant difference between the groups in any of the outcomes studied, including primary graft dysfunction, 30-day mortality, 1-year survival, chronic lung allograft dysfunction-free survival, and overall survival. In univariate analysis, the Oto lung donor score was the only factor associated with 1-year survival (score of 6 in alive patients vs score of 7 in dead patients; P = .04); donor age 65 years old or older was not. CONCLUSIONS: Carefully selected lung grafts from donors 65 years of age or older are associated with outcomes similar to those reported with grafts from younger donors Grafts from older donors thus provide an interesting option to expand the donor pool during a shortage.

OBJECTIVES: To report the outcomes of surgical treatment of calf intramuscular venous malformations (IMVMs) on pain, functional limitation, and quality of life. METHODS: We retrospectively reviewed 57 consecutive patients who had surgery for IMVM of the posterior compartment of the leg between 2010 and 2015. Treatments were all done at a single institution. RESULTS: Patients presented with pain (52), muscle contracture (14), or pulmonary embolism (4). Muscle involvement included the soleus muscle (n = 28, 49%), the gastrocnemius muscle (n = 25, 43%), and deep muscles (n = 4, 7%). Complete excision was possible in 52 patients (91%) and partial excision in 5 (9%). Thirty-five of 46 patients who had an MRI follow-up at six months had no residual venous malformation. At the final follow-up (mean 39 months), 32 of 40 patients seen had no residual pain and 37 had no residual functional impairment. CONCLUSION: In cases where IMVM is located in one muscle in the leg, we demonstrated that surgery yielded improvement in pain, function, and quality of life.

OBJECTIVES: In lung transplantation (LT), femoral venoarterial extracorporeal membrane oxygenation (VA-ECMO) usually requires an open approach that may be associated with severe groin wound infection. In endovascular aortic procedures, preclosing of the femoral artery (PFA) with vascular closure devices allows the percutaneous insertion and withdrawal of large-bore cannulae. We sought to evaluate whether this innovative technique could be applied in the specific setting of LT to achieve total percutaneous VA-ECMO and decrease groin wound infection. METHODS: We conducted a retrospective study of a prospective database including patients who underwent LT in our centre from January 2011 to December 2017. Patients who underwent peripheral VA-ECMO using the PFA technique after January 2014 (PFA group, n = 106) were compared to those who underwent peripheral VA-ECMO using open cannulation and/or decannulation before January 2014 (non-PFA group, n = 48). The primary end point was the rate of technical success defined as total percutaneous VA-ECMO. Secondary end points included groin wound infections and delayed vascular complications. RESULTS: The PFA technique was technically successful in 98 patients (92.5%). As compared with the non-PFA group, the PFA group was characterized by a similar rate of vascular complications (16.6% vs 11.3%, P = 0.360) and a decreased rate of groin wound infection (18.9% vs 0%, P < 0.001). In multivariate analysis, risk factors associated with vascular complications following PFA included female sex, peripheral arterial disease and ECMO duration. CONCLUSIONS: In LT patients, PFA is associated with a high rate of total percutaneous VA-ECMO, thus preventing the occurrence of groin wound infection.

BACKGROUND: The aim of this study was to evaluate outcomes of extensive iliofemoral reconstruction combining both iliac covered kissing stents (ICKS) with stenting of the external iliac artery (SEIA) and/or surgical femoral endarterectomy (SFE). METHODS: From November 2010 to November 2017, patients with extensive iliofemoral occlusive disease-classified as Trans-Atlantic Inter-Society Consensus class D-treated by ICKS in combination with SEIA and/or SFE were included. Patients received ICKS + SEIA, ICKS + SFE, or ICKS + SEIA + SFE. Demographics, procedure details, and postoperative outcomes were recorded. Primary end points were primary patency (PP), primary assisted patency (PAP), and secondary patency (SP). Long-term patency was assessed by annual clinical and ultrasonographic examination. RESULTS: Among 156 consecutive ICKS procedures performed during the study period, 59 patients were included (81% men; median age, 65 years). In all, 32 patients (54%) underwent ICKS + SEIA, 17 (29%) patients underwent ICKS + SFE, and 10 (17%) patients underwent ICKS + SEIA + SFE. Operative indication was either disabling claudication (n = 46, 78%) or critical limb-threatening ischemia (n = 13, 22%). A total of 92 limbs were revascularized, including 121 covered balloon-expandable stents and 65 self-expanding nitinol stents, with 100% technical success. Thirty-day mortality was 3% (2/59) and 5 (8%) patients suffered from local complications, with no early reintervention. Long-term patency rates were as follows: at 2 years, overall PP, PAP, and SP were 82%, 86%, and 96%, respectively; at 5 years, overall PP, PAP, and SP were 73%, 79%, and 95%, respectively. After a mean follow-up of 34 ± 29 months, 25% (15/59) patients underwent late reinterventions for either de novo iliac or femoral stenosis (n = 9), iliac occlusion (n = 4), or external iliac in-stent restenosis (n = 2). CONCLUSIONS: Treatment of extensive iliofemoral occlusive disease involving ICKS in combination with SEIA and/or SFE is safe and effective, providing satisfactory long-term secondary patency, at the price of a significant reintervention rate.

OBJECTIVE: In Marfan syndrome (MFS) patients, endovascular repair carries a risk of aortic wall injury, which may result in retrograde aortic dissection, dilatation, or false aneurysm at the landing zones. It was hypothesised that potentially these complications may be avoided using modified practices. This study aimed to describe experience of a specific protocol for endovascular aortic repair in patients with MFS. METHODS: All MFS patients treated by aortic endovascular repair between February 2015 and August 2018 were included prospectively. The following rules were applied: (i) excluding stent grafts with bare stents and barbs, (ii) proximal landing in a pre-existing graft, or (iii) minimising proximal oversizing when landing in the proximal native aorta (<10%), and (iv) distal undersizing for chronic dissection cases. RESULTS: In eighteen patients (55% men, mean age: 47 ± 17 years), the index procedures were initial endovascular aortic repair (n = 10), elephant trunk completion (n = 6), and anastomotic pseudo-aneurysm after thoracic open repair (n = 2). The technical success rate was 100%. Proximal landing was in the native aorta in 11 patients (61%), with a mean proximal oversizing of 2.4 mm (8% oversized). Distal landing in the native aorta was performed in 16 cases (89%), with a mean distal undersizing of 8.9 mm (- 23%). No mortality, spinal cord ischaemia, stroke, or retrograde aortic dissection occurred post-operatively. One type 1b endoleak was observed. The mean follow up was 21.4 months. Aortic aneurysm related mortality was 5% (n = 1) and occurred after distal thoraco-abdominal surgery planned from the outset (prior to endovascular repair). Another patient presented a proximal landing zone complication with aortic enlargement. The mean maximum aortic diameter decreased significantly from 59 mm to 45 mm (p = .0005) after treatment. CONCLUSION: The specific protocol described in this study seems to optimise the results of endovascular aortic repair in MFS patients with significant aortic remodelling.

Median arcuate ligament (MAL) syndrome usually involves the celiac artery (CA) only. Far less frequently, both the CA and superior mesenteric artery (SMA) are compressed, leading to chronic mesenteric ischemia. We report the case of a 46-year-old woman with a 4-year history of permanent nausea, postprandial abdominal pain, and asthenia. A clear epigastric bruit was observed on physical examination. Duplex ultrasound and computed tomography angiography revealed an occlusion of the CA and a highly compressed proximal SMA by the MAL, with an important collateral mesenteric network. Laparoscopic release of the MAL using a transperitoneal retrorenal approach was performed, with excellent postoperative outcomes. Compression of the SMA by the MAL is a rare cause of chronic mesenteric ischemia. Laparoscopic release of the SMA from the MAL using a transperitoneal retrorenal approach is safe and effective. Long-term outcomes need to be further assessed.

OBJECTIVE: Failure of thoracic endovascular aortic repair (TEVAR) in chronic aortic dissections can be partially explained by retrograde false lumen (FL) flow through distal re-entry tears. After implantation of a thoracic stent graft, FL thrombosis occurs in less than 50% of the cases. The objectives of this study were to describe the feasibility and outcomes of FL embolization in patients with chronic aortic dissections. METHODS: Between June 2015 and January 2018, 27 patients (mean age, 61 ± 14 years) with chronic aortic dissection underwent FL embolization as an adjunct during or after TEVAR placement procedure. Indications for embolization were (1) symptomatic chronic aortic dissections with pain or rapid growth of aortic diameter (≥5 mm/y) requiring rapid exclusion of the aneurysm, (2) aneurysmal dilatation with persistent FL retrograde flow after TEVAR, and (3) large FL aneurysms (≥55 mm) that might lead to persistent retrograde flow. Twenty patients presented with type B chronic aortic dissections (74.1%) and seven presented a residual type A chronic aortic dissections (25.9%). Eight patients had a previous aortic arch replacement (29.6%). Six patients had previous repair with TEVAR (22.2%). The delay between the onset of dissection and the first endovascular repair was 47 months (range, 3-144). Spinal fluid drainage was used in 74.1% of cases (20/27 patients). Embolization devices included coils and vascular plugs. RESULTS: The technical success rate was 100% (27/27). Complete spinal cord ischemia was observed in one patient (3.7%). There was one hospital death from pneumonia after zone 1 supra-aortic trunk debranching with TEVAR and embolization. After the index procedure, FL thrombosis was observed in 81.5% of patients (22/27) on late phase computed tomography angiography. Five patients required two or more embolization procedures, leading to a high rate of complete FL thrombosis (92.6%). One patient presented a type IB endoleak and one patient presented a type II endoleak. Radiologic follow-up was 20 ± 10 months. The maximum thoracic aortic diameter significantly decreased from 63 mm to 54 ± 10 mm (P < .001). CONCLUSIONS: Embolization of the FL of chronic aortic dissections is technically feasible with a low morbidity rate. The FL thrombosis is observed in the majority of case and promotes favorable thoracic aortic remodeling. Longer follow-up is needed to confirm these good results on the thoracic aorta and this technique may, therefore, improve the results of TEVAR in chronic aortic dissections.
