Low Profile Off the Shelf Multibranched Endografts for Urgent Endovascular Repair of Complex Aortic and Thoraco-abdominal Aneurysms in Patients with Hostile Iliac Access: European Multicentre Observational Study

The aim of the study was to report outcomes of a thoraco-abdominal, custom made, low profile (outer diameter 20 Fr) four branched endograft used as an off the shelf (OTS) solution for urgent juxta/pararenal abdominal aortic aneurysms (J/P-AAAs) and thoraco-abdominal aortic aneurysms (TAAAs) in the presence of hostile femoral/iliac access. Data for patients who underwent endovascular repair for urgent J/P-AAAs and TAAAs with hostile femoral/iliac access by a low profile, four branched endograft in four European aortic centres between 2019 and 2023 were prospectively collected and retrospectively analysed. The investigated device was a custom made endograft with the configuration of a standard T-branch, used as an OTS solution for urgent cases with hostile femoral/iliac access. Access related complications, spinal cord ischaemia (SCI), and 30 day mortality were assessed as primary outcomes. Survival, freedom from re-interventions (FFRs), and iliac limb occlusion (ILO) were evaluated as secondary outcomes. Fifty five cases were enrolled: ruptures, n = 14 (25%); symptomatic, n = 12 (22%); and asymptomatic TAAAs with diameter ≥ 80 mm, n = 29 (53%). The were seven (13%) J/P-AAAs and 48 (87%) TAAAs. The median right and left external iliac artery diameters were 6.7 (interquartile range [IQR] 5.5, 7.9) mm and 7.1 (IQR 6.5, 8.7) mm, respectively. Bilateral hostile femoral/iliac access was reported in 39 patients (71%). Access related complications occurred in five cases (9%). There were four cases (7%) of SCI with two permanent paraplegias. Four patients (7%) died within 30 days. The median follow up was 22 (IQR 11, 33) months. Overall, eight patients (15%) required re-interventions: four within 30 days and four during follow up. No ILO occurred. Estimated one year FFRs and survival was 91% and 87%, respectively. Low profile OTS thoraco-abdominal endograft seems safe and effective to manage urgent J/P-AAAs and TAAAs in the presence of hostile femoral/iliac access. Further larger studies with long term follow up are needed to validate this preliminary experience.

Urgent endovascular repair of juxtarenal/pararenal aneurysm by off-the-shelf multibranched endograft

ObjectiveTo report outcomes of urgent juxtarenal/pararenal aneurysms (J/P-AAAs) managed by off-the-shelf multibranched thoracoabdominal endografts (Cook, T-branch). MethodsIn this observational, multicenter, retrospective study, patients with J/P-AAAs treated by urgent endovascular repair by T-branch in 23 European aortic centers, from 2013 to 2023, were analyzed. Contained J/P-AAAs rupture, presence of related symptoms, and aneurysm diameter of >70 mm were considered as indication for urgent repair. Technical success (TS), spinal cord ischemia (SCI), and 30-day/hospital mortality were assessed as early outcomes. Survival, freedom from reinterventions, and target artery instability (TAI) were evaluated during follow-up. ResultsOverall, 197 patients (J-AAAs, n = 64 [33%]; P-AAAs, n = 95 [48%]; previous failed endovascular aneurysm repair (EVAR), n = 38 [19%]) were analyzed. The mean age and aneurysm diameter was 75 ± 8 years and 76 ± 4 mm, respectively. The American Society of Anesthesiologists score was 3 and 4 in 118 (60%) and 79 (40%) patients. Rupture, symptoms, and diameter of >70 mm were present in 51 (26%), 110 (56%), and 53 (27%) patients, respectively. An adjunctive proximal thoracic endograft was used in 28 cases (14%). The mean aortic coverage between the upper portion of the endograft and the lowest renal artery was 154 ± 49 mm. Single-stage repair and cerebrospinal fluid drainage were reported in 144 (73%) and 53 (27%) cases, respectively. TS was achieved in 182 (92%) cases (rupture, 84% vs no rupture, 95%; P = .02). Failures consist of TA loss (11 [6%]: renal artery, 9; celiac trunk, 2), type I to III endoleaks (2 [1%]), and 24-h mortality (2 [1%]). Rupture was a risk factor for technical failure (P = .02; odds ratio [OR], 3.8; 95% confidence interval [CI], 1.1-12.1). Overall, 15 patients (8%) had persistent SCI (rupture, 14% vs no rupture, 5%) with 11 (6%) , of paraplegia (rupture, 10% vs no rupture, 5%; P = .001). Rupture (P = .04; OR, 3.1; 95% CI, 1.1-8.9) and adjunctive proximal thoracic endograft (P = .01; OR, 4.1; 95% CI, 1.3-12.9) were risk-factors for SCI. Twenty-two patients (11%) died within 30 days or during a prolonged hospitalization. Previous failed EVAR (P = .04; OR, 3.6; 95% CI, 1.1-12.3), paraplegia (P < .001; OR, 9.9; 95% CI, 1.6-62.2) and postoperative mesenteric complications (P = .03; OR, 10.4; 95% CI, 1.2-93.3), as well as cardiac (P = .03; OR, 8.2; 95% CI, 2.0-33.0) and respiratory (P < .001; OR, 10.1; 95% CI, 2.9-35.2) morbidities were associated with 30-day/hospital mortality. The mean follow-up was 19 ± 5 months. The estimated 3-year survival and freedom from reinterventions was 58% and 77%, respectively. TAI occurred in 27 patients (14%) (occlusion, 15; endoleak, 14) with an estimated 3-year freedom from TAI of 72%. ConclusionsUrgent repair of J/P-AAAs by T-branch is feasible and effective with satisfactory TS and 30-day/hospital mortality in high-risk patients. However, extensive aortic coverage is necessary, leading to a non-negligible SCI rate, especially in case of aortic rupture or when adjunctive thoracic endografts are necessary. Previous failed EVAR and postoperative mesenteric complications, as well as cardiac and respiratory morbidities were associated with 30-day/hospital mortality and should be subjected to more research for the purposes of improving outcomes.

Multicenter Outcome With the Chimney Technique After Urgent Endovascular Repair of Ruptured Abdominal Aortic Aneurysms

Systematic Review and Meta-analysis of Short-term and Mid-term Outcomes After Use of t-Branch Off-the-shelf Multibranched Endograft for Elective and Urgent Treatment of Thoracoabdominal Aortic Aneurysms.

To conduct a meta-analysis to assess the safety and efficacy of t-Branch off-the-shelf multibranched endograft for the treatment of thoracoabdominal aortic aneurysm (TAAA). PubMed, Embase, and Web of Science. Online databases were searched from June 2012 to March 2023. The data were pooled together using a random-effects model of proportions. The outcomes overall included technical success, spinal cord ischemia, target vessel occlusion, type I or III endoleak, reintervention, early mortality (30-day), and mid-term outcomes. Subgroup meta-analyses and meta-regression were performed to explore variation among studies. A total of 15 studies containing 1238 patients were included in the meta-analysis. The overall study quality assessment was found to be moderate to good. The pooled technical success was 97.0% (95% confidence interval [CI]=95.5-98.6, I2=53.01%, 1185/1238 cases, 15 studies). Overall, early mortality was 7.3% (95% CI=4.4-10.1, I2=74.48%, 124/1238 cases, 15 studies). Early spinal cord ischemia was 13.4% (95% CI=9.6-17.2, I2=67.24%, 160/1238 cases, 15 studies), and early type I or III endoleak was 6.0% (95% CI=3.4-8.5, I2=53.71%, 68/1032 cases, 9 studies). Mid-term outcomes showed target vessel occlusion was 4% (95% CI=1.4-6.5, I2=65.18%, 28/528 cases, 10 studies, 5-21.2 months), type I or III endoleak was 4.7% (95% CI=2-7.5, I2=49.74%, 38/512 cases, 10 studies, 5-21.2 months), reintervention was 11.2% (95% CI=8.1-14.3, I2=31.06%, 85/650 cases, 10 studies, 5-21.2 months), and pooled mortality was 13.9% (95% CI=7.2-20.7, I2=76.32%, 84/550 cases, 11 studies, 5-21.2 months). Meta-regression found a significant linear association between higher technical success and earlier publication year (p=0.014) and studies with anatomic inclusion criteria (p=0.037). Urgent patients (p=0.021) and later publication year (p=0.048) were significantly associated with higher early mortality. The use of the off-the-shelf t-Branch multibranched endograft for elective or urgent endovascular TAAA repair is associated with high technical success rates and proved to be safe and effective at early and mid-term follow-up. However, the heterogeneity between the included studies is high, and prospective, randomized studies along with future larger studies with long-term follow-up are needed. The Zenith t-Branch (Cook Medical, Bloomington, Ind) was approved as a commercially available device in Europe in June 2012. Although a decade has past, the outcomes of t-Branch have rarely been synthesized at the global level. This meta-analysis included 15 studies containing 1238 patients. The meta-analyses included technical success, major adverse events, reintervention, early mortality, and mid-term outcomes. The outcome was very meaningful and representative for the use of t-Branch. It is helpful for endovascular surgeons to make decisions on the treatment of TAAA patients.

Transcarotid thoracic endovascular aortic repair for rupture of the aortic isthmus due to high energy blunt trauma: A case report

Introduction: Blunt thoracic aortic injury (BTAI) is associated with very high mortality, and managing currently favors thoracic endovascular aneurysm repair (TEVAR) if feasible, especially BTAI due to high energy force, where patients usually suffer from polytrauma, which requires rapid discover and treat spontaneously. However, a remarkable group of patients is contraindicated for the transfemoral route- the established first-line approach in endovascular interventions of the aorta. Here, we report a successful case in which the carotid artery was used to perform TEVAR. Case presentation: A young female was transferred to our emergency department after injuries sustained by falling from the fifth floor. Her vital signs were stable on admission. Pan CT scan revealed multiple injuries: A grade III injury of the aortic isthmus, a grade III liver injury without active bleeding, and fracture of the sternum, multiple ribs, T12-L1 vertebral body, and pelvic ring. However, her hemodynamics became unstable, and we decided to perform an urgent endovascular repair. During preparations for TEVAR, we found that the diameter at the proximal landing zone was 17.1mm, so it cannot be accommodated by any of the available thoracic endograft devices. Under the emergency condition, we decide to perform TEVAR by abdominal aortic device and access via the carotid to suit the device's length. After inpatient rehabilitation, she was discharged without neurologic sequelae. Conclusion: Transcarotid TEVAR is feasible and could be considered as an alternative approach in some specific patients with BTAI.

Urgent Juxtarenal Aortic Aneurysm Repair With Modified Off-the-shelf Endograft to Preserve Intercostal Arteries and Branch Incorporation by Transfemoral Access.

To demonstrate the feasibility of the modification to preserve intercostal arteries of the t-Branch Endograft (Cook Medical, Bloomington, IN) in an urgent setting, associated with a less invasive approach for branch incorporation from percutaneous femoral access with steerable sheaths. A 73-year-old female patient presented at our institution with intense abdominal pain. Angiotomography showed a 50-mm juxtarenal aortic aneurysm, with no signs of rupture. Urgent endovascular repair was indicated due to abdominal symptom with an off-the-shelf multi-branched endograft. To limit descending thoracic aortic coverage, we performed t-Branch modification to preserve intercostal arteries and minimize the risk of spinal cord injury, associated with a percutaneous transfemoral approach and branch incorporation with steerable sheaths to avoid the risks associated with a superior axillary or brachial access. Control angiotomography showed adequate aneurysm sac exclusion with patency of all four visceral vessels. t-Branch-modified endograft to limit aortic coverage is an alternative option in urgent cases to diminish the risk of spinal cord injury, and association of steerable sheaths with branch incorporation is leading complex aortic repairs to an even less invasive procedure. This paper highlights the possibility of performing complex endovascular aortic repair in an urgent setting with modification of an off-the-shelf multi branched endograft limiting intercostal arteries coverage, thereby diminishing the risk of spinal cord ischemia. This technical innovation provides an alternative for clinicians when treating large, rapidly expanding, or symptomatic juxtarenal, pararenal, paravisceral or type 4 thoracoabdominal aortic aneurysms that could not wait for a custom-made device and do not need extensive thoracic aortic coverage that an off-the-shelf device provides. In summary, expand the possibilities of an endovascular repair of complex aortic aneurysms.

Urgent endovascular aorta repair for a rupture of a traumatic infrarenal aortic dissection: Case report and review of literature

Traumatic aortic injury is a life-threatening condition usually followed by blunt trauma with damage at the thoracic aorta. Abdominal aortic injuries are rare and usually seen with seatbelt trauma. Timing and approach of treatment are associated with significant morbidity and mortality. This case concerns a 66-year-old man with a high impact trauma after a fall from height. Upon presentation in our level two trauma center, he was conscious but hemodynamically unstable. Computer Tomography scan revealed multiple rib, spine and pelvic fractures with bilateral lung contusions warranting a transfer to a level one trauma center. However, an infrarenal aortic dissection with a retroperitoneal rupture and active bleeding necessitated acute surgical intervention. He was treated endovascularly with an off-the-shelf aortic stent graft which is meant for aortic aneurysm repair. Surgery was performed percutaneously under local anesthetic. Other fractures were treated conservatively. Postoperatively, the patient made a swift recovery without any complications in follow-up. As this case demonstrates, urgent endovascular repair of a traumatic infrarenal aortic injury can be done quickly with a minimally invasive approach with conventional stent graft systems thereby reducing the high morbidity and mortality rates associated with this life-threatening condition.

The management of patients with popliteal artery aneurysms presenting with acute limb ischemia

ObjectiveEndovascular popliteal artery aneurysm (PAA) repair has acceptable outcomes compared with open repair for elective therapy. Endovascular repair for urgent PAA causing acute limb ischemia (ALI) has not been well-studied. This project compares outcomes of urgent endovascular and open repair of PAA with ALI. MethodsThe Vascular Quality Initiative database for peripheral vascular interventions (PVIs) and infrainguinal bypass were reviewed for PAAs with ALI from 2010 to 2021. Only patients entered as having symptoms of ALI in the PVI module and ALI as indication in the infrainguinal bypass module were included. In addition, patients undergoing elective treatment were excluded and the sample analyzed was restricted to patients undergoing urgent and emergent open and endovascular repair. Patient demographics and comorbidities as well as procedural details were compared between the two groups. Perioperative complications up to 30 days were compared as well as long-term outcomes including major amputation and mortality at 1 year. ResultsUrgent PAA repair for ALI constituted 10.5% (n = 571) of all PAAs. Most urgent repairs were open (80.6%; n = 460) with 19.4% (n = 111) endovascular. The proportion of endovascular repair significantly increased from 16.7% in 2010 to 85.7% in 2021. Patients undergoing endovascular repair were older (71.2 ± 12.5 vs 68.0 ± 11.8; P = .011) than patients undergoing open repair. They were also more likely to have coronary artery disease (32.4% vs 21.7%; P = .006). Open PAA repair was associated with more bleeding complications (20.8% vs 2.7%; P < .001), longer postoperative length of stay (8.1 ± 9.3 days vs 4.9 ± 5.6 days; P < .001), and less likelihood of discharge to home (64.9% vs 70.3%; P = .051). Perioperative major amputation rate was 7.5% with no difference between the two treatment strategies up to 1 year. However, patients receiving endovascular repair had higher inpatient (1.1% vs 0%; P < .001), 30-day (6.3% vs 0.4%; P < .001), and 1-year (16.5% vs 8.4%; P = .02) mortality. Multivariable regression analysis suggested that endovascular repair was possibly associated with increased 30-day mortality, but not 1-year mortality. ConclusionsEndovascular PAA has exponentially increased from 2010 to 2021. Endovascular repair is associated with decreased complications and hospital length of stay. The increased perioperative mortality seen in this group is likely due to selection bias.

Uncommon indication for an Octopus technique in a symptomatic infected thoracoabdominal aneurysm after thoracic endoprosthesis

Emergent thoraco-abdominal aneurysms (TAAA) repair remains challenging. Endovascular treatment should be considered in patients unfit for open surgery. Octopus technique is an off-the-shelf solution suitable for selected situations. We describe the successful treatment of a symptomatic and infected TAAA. A 66-year-old man presented to the emergency department with an infected 92mm TAAA with impending rupture due to Type 1b endoleak following previous TEVAR. 18FDG-PET-CT ruled out an endograft infection but diagnosed an aortitis.. Considering the emergent setting and his comorbidities, the patient was treated with the Octopus technique. Both renals were sacrificed and the celiac trunk was previously occluded, leaving the superior mesenteric artery the only target vessel. Treatment was successful and patient went home with a lifelong oral antibiotherapy. The 6-months angio-CT confirmed the absence of endoleak and patent superior mesenteric artery. The Octopus procedure can be used in selected cases for urgent endovascular TAAA repair in patients who are unfit for open repair.

The Management of Popliteal Artery Aneurysms With Acute Limb Ischemia in the Vascular Quality Initiative

Endovascular popliteal artery aneurysm (PPA) repair has acceptable outcomes compared with open repair for elective therapy. However, endovascular repair for urgent PAA causing acute limb ischemia (ALI) has not been well studied. This project compares the outcomes of urgent endovascular and open repair of PAA presenting with ALI.

Endovascular Procedure in Patient with Ruptured Abdominal Aortic Aneurysm after High-Risk Early Percutaneous Coronary Intervention

Abstract Purpose The aim of the study is to present the success of an endovascular procedure for ruptured abdominal aortic aneurysm (AAA) patient with high-risk non-ST elevation myocardial infarct (NSTEMI) after early percutaneous coronary intervention (PCI). Case Report A 56-year-old man came to our emergency room with a history of early PCI in the previous hospital and received dual antiplatelet therapy (DAPT). His COVID-19 test result was unknown. This patient was then being re-examined and was diagnosed with ruptured AAA. Despite his pending COVID-19 laboratory results, we decided to perform an urgent endovascular aortic repair (EVAR) in this patient, considering his DAPT consumption history. The procedure was successful and the patient's condition after EVAR showed improvements. Conclusion In patients with ruptured AAA with high-risk NSTEMI who just underwent early PCI and recently received DAPT, endovascular procedure can be considered as the treatment of choice since open surgery repair is contraindicated.

Multiple Parallel Grafts for Urgent Endovascular Repair of a Ruptured Mycotic Aortic Aneurysm.

A 73-year-old woman underwent urgent endovascular repair of a ruptured mycotic aortic aneurysm. A thoracic stent graft was employed as the main endograft, while the celiac trunk and superior mesenteric artery were revascularized by the chimney technique and the renal arteries through the periscope technique. Postoperative computed tomography revealed a Type A1 gutter, treated by detachable coils and peripheral occlusion devices. Six-month follow-up revealed patency of the stent grafts, without endoleak or stent graft infection signs.

Multi-Branched Thoracoabdominal Endovascular Aortic Repair With Branch Access Through a Left Thoracotomy and Descending Thoracic Aortic Conduit: A Novel and Effective Alternative Access

Purpose: To demonstrate an alternative access to perform directional branch catheterization during complex endovascular aortic repair. Technique: Urgent endovascular aortic repair was indicated to treat a symptomatic post dissection thoracoabdominal aneurysm with large infrarenal dilatation with an off-the-shelf t-Branch endograft (Cook Medical, Bloomington, IN, USA). Traditional proximal arterial accesses were not suitable due to a previous aortic arch endograft. A novel approach was performed through a left postero-lateral thoracotomy, isolation of the descending thoracic aorta and anastomosed a polyester graft conduit to allow sheaths passage to the thoracoabdominal aorta with subsequently directional branch catheterization. Conclusion: The descending thoracic aortic conduit technique is an effective alternative for directional branch catheterization and should be considered whenever traditional proximal arterial accesses are not suitable and other endografts configurations not considered due to anatomic limitations.

Calcium Rim Sign in Plain Abdominal Radiograph: An Underrated Alert for Unstable Abdominal Aortic Aneurysm

Abdominal pain is a common presentation in the emergency department, and constipation is one of the commonest causes in elderly patients. We report a patient with a ruptured abdominal aortic aneurysm (AAA) who presented with features mimicking acute bowel obstruction. The abdominal radiograph, which showed a calcium rim sign, raised the suspicion of AAA. It was confirmed with contrast-enhanced computed tomography, which showed a large ruptured AAA. The patient was transferred immediately to a vascular center for urgent endovascular repair of AAA and made a complete recovery. This case highlighted the usefulness of plain abdominal radiography in diagnosing abdominal pain, which should not be taken for granted as it can aid in raising concerns of AAA. This case sends an important message, particularly to junior doctors, that symptoms of abdominal pain, vomiting, and total constipation can mask the possibility of AAA. Immediate treatment of a ruptured aortic aneurysm requires a high index of clinical suspicion.

Urgent endovascular repair of thoracoabdominal aneurysms using an off-the-shelf multibranched endograft.

Our goal was to report outcomes of the endovascular repair of urgent thoracoabdominal aortic aneurysms (TAAAs) using the Cook Zenith t-Branch off-the-shelf multibranched endograft. Between 2010 and 2020, we collected patients with TAAAs who received an urgent endovascular repair using the Cook Zenith t-Branch (had a rupture, symptoms or diameter >80 mm). Thirty-day mortality, spinal cord ischaemia (SCI) and clinical success were assessed as early outcomes. Freedom from reintervention, target visceral vessel patency and survival were considered during follow-up. Sixty-five cases were managed using the Cook Zenith t-Branch for 27 (42%) TAAA ruptures, 8 (12%) symptomatic TAAAs and 30 (46%) asymptomatic TAAAs with a diameter >80 mm. Crawford's extent I-II-III and IV were noted in 54 (83%) and 11 (17%), respectively. Eleven (17%) patients had SCI with 3 (5%) cases of permanent paraplegia. Postoperative dialysis (P = 0.04) and ruptured TAAAs (P = 0.05) were associated with SCI. Sixteen (25%) patients had reinterventions within the first 30 days postoperatively. The 30-day mortality was 14% (9). Ruptured TAAAs (P = 0.05) and technical failures (P = 0.01) were correlated with in-hospital mortality. Clinical success was 78% (51 patients). The mean follow-up was 18 ± 14 months. Survival at 24 months was 47% with no late TAAA-related deaths. Patients with ruptured TAAAs had lower survival than those who did not have ruptured TAAAs (52% vs 60% at 1 year; P = 0.05). Target visceral vessel patency and freedom from reintervention at 24 months were 89% and 60%, respectively. An off-the-shelf multibranched endograft is safe and effective for treating urgent TAAAs. Postoperative SCI and 30-day mortality are satisfactory for this challenging clinical scenario. The early reintervention rate is not negligible. Midterm survival is low, especially in patients with a ruptured TAAA; therefore, accurate patient selection is mandatory.

Predictors of Outcome in Urgent Endovascular Aneurysm Repair for Ruptured Abdominal Aortic Aneurysm in Octogenarian Patients: Abdominal Aortic Aneurysms

Introduction: The introduction of endovascular aneurysm repair (EVAR) for ruptured abdominal aortic aneurysms (rAAAs) has led to a significant overall amelioration of both peri-operative and 30 day mortality; however, octogenarians with rAAAs remain an extremely high risk group, even if treated with EVAR. The aim of this study was to evaluate the efficacy of urgent EVAR (uEVAR) in patients aged > 80 years with rAAAs.

Endovascular Management of a Subclavian Arterial Injury During Central Venous Catheter Placement for Hemodialysis.

Subclavian artery injuries after central venous catheter placement constitute a rare but potentially fatal complication. The surgical repair of a subclavian artery trauma is a real challenge, associated with a high rate of morbidity and mortality. The role of endovascular treatment for vascular trauma, including injury to the subclavian artery, continues to evolve. In this manuscript, we report the case of an urgent endovascular repair by a covered stent graft of a subclavian artery perforation following the placement of a central venous catheter for dialysis in a 52-year-old patient, having a chronic kidney failure stage 5, with multiple comorbidities. The present case suggests that attention needs to be paid to preventing iatrogenic arterial cannulation during central vein catheterization to avoid potentially devastating complications. Endovascular treatment using a covered stent should be attempted as a first-line therapeutic option.

Stent Graft Modification to Preserve Intercostal Arteries Using Thoracoabdominal Off-the-Shelf Multibranched (t-Branch) Endograft

Purpose: To demonstrate an off-the-shelf multibranched (t-Branch) modification to allow intercostal arteries preservation during juxtarenal, pararenal, paravisceral, and extent IV thoracoabdominal aortic aneurysm repair. Technique: The t-Branch is an off-the-shelf device not customized for specific patient anatomy and may be offered for urgent endovascular repair for patients with complex aortic aneurysms. However, a concern when treating patients who do not aneurysms extending above the celiac axis is that the more proximal extension which is required with this device may render patients at high risk for spinal cord injury. We report a novel technique with t-Branch modification performing a 180° fabric back windows at the first 2 sealing stents that allow perfusion to the intercostal arteries. Conclusion: T-Branch-PIA (preserving intercostal arteries) modification limits intercostal arteries coverage while optimizing proximal seal zone in juxtarenal, pararenal, paravisceral, and extent IV thoracoabdominal aneurysms, thereby may decrease the risk of spinal cord injury.

Urgent Endovascular Treatment of Iliac Artery Pseudoaneurysm in Patient with Ehlers-Danlos Syndrome: A Case Report

BACKGROUND: Ehlers-Danlos syndrome (EDS) type IV is a heritable disorder of connective tissue that is mainly associated with vascular maladies such as aneurysms, pseudoaneurysms, and dissections with or without spontaneous rupture. Historically, vascular complications in EDS IV have been treated conservatively whenever possible, due to the high morbidity and mortality after vascular interventions, whether open or endovascular. We present a case of a ruptured pseudoaneurysm of the right common iliac artery in a 18-year-old male, who was successfully treated by endovascular approach and later diagnosed with EDS type IV.&#x0D; CASE PRESENTATION: A 18-year-old male patient was admitted in ER with sharp pain in the right hypogastrium, hypotensive and with reduced blood parameters. Multiphasic modern computed tomography (MDCT) scan of abdomen and pelvis revealed massive ride sided pelvic and retroperitoneal hematoma. The presence of pseudoaneurysms on both common iliac arteries (CIA) was detected, with small ulcer on the right side and a focal dissection on the left side. An urgent endovascular repair of the ruptured pseudoaneurysm on the right CIA with covered stent was performed. Patient’s laboratory parameters and clinical status improved significantly within the next few days.&#x0D; CONCLUSIONS: Vascular repair in EDS-IV patients carries significant risk and should be indicated very carefully. Endovascular treatment for these patients is feasible and should be considered as an alternative to open surgery in some challenging cases as this one.
