Visceral Artery Aneurysms

Purpose: To retrospectively report a large single-center experience of visceral artery aneurysms (VAAs) and pseudoaneurysms (VAPAs) treated with covered stenting (CS) as the first therapeutic option vs transcatheter embolization (TE). Methods: One hundred patients (mean age 59±14 years; 58 men) underwent 59 elective and 41 emergent endovascular procedures to treat 51 VAAs and 49 VAPAs. Seventy patients had TE and 30 received CS (27 Viabahn and 3 coronary stent grafts). Both TE and CS were performed in 10 cases. Results: Technical success was 96% (97% CS, 96% TE), and 30-day clinical success was 83% (87% CS, 81.4% TE). Four major complications occurred; 30-day mortality was 7%, mainly due to septic shock following pancreatic surgery. The midterm follow-up was 20.8 months in the total population and 32.8 months in the CS group. More than 6 months after CS all aneurysms remained excluded; stent patency was achieved in 88%. Twelve CS patients with >3 years’ follow-up had maintained stent patency. Conclusion: In endovascular treatment of visceral aneurysms, covered stenting was feasible in 30%. CS showed a slightly better efficacy than TE and good midterm patency. The Viabahn covered stent seems to be suitable for endovascular repair of tortuous visceral arteries affected by true or false aneurysms.

Visceral Artery Aneurysms

Methods: It is a retrospective review of prospectively kept data of patients treated for visceral artery aneurysms in Tribhuvan University Teaching Hospital and Manmohan Cardiothoracic Vascular and Transplant Center from 1997 to 2009.Results: Fifteen patients were diagnosed with 16 visceral artery aneurysms. These consisted of 7 splenic (in 6 patients), 4 hepatic, 2 superior mesenteric, 1 gastroduodenal, and 1 renal artery aneurysms. There were 14 symptomatic patients including 4 who presented with rupture. Commonest presenting symptom was pain abdomen (14/15), followed by gastrointestinal bleed (6/15) and mass abdomen (5/15). The diagnosis was made with the help of CECT of abdomen in 13 patients, which was confirmed by conventional angiography in three patients. In two patients with obscure GI bleeding, diagnosis was clinched by conventional angiogram. Eight patients were treated only surgically, with three mortality. Transcatheter embolization alone was used in 5 patients. Two patients were treated with combination of surgical and endovascular therapy. One patient with superior mesenteric artery aneurysm in whom nothing could be done during laparotomy died six months later. Average follow up duration was one year.Conclusion: Splenic artery remains the most commonly afflicted vessel among the visceral artery aneurysms. The VAAs can be treated surgically or with endovascular means with fair success, although the best mode of treatment needs to be individualized.Journal of Society of Surgeons of NepalVol. 17, No. 2, 2014, Page: 3-6

AbstractEndovascular management of small visceral artery aneurysms is an established treatment with satisfactory outcomes. However, when size exceeds 5 cm visceral aneurysms are considered as “giant” (giant visceral artery aneurysms or GVAAs) and management is significantly more complex. Between August 2007 and June 2019 eleven cases of GVAAs that were endovascularly treated were retrospectively reviewed and included in this single center study. Mean size was 80 mm (± 26.3 mm) x 46 mm (+ \-11.8 mm). Nine of the lesions were true aneurysms, and two were pseudoaneurysms. In 8 patients, the lesion was causing compression symptoms in the surrounding organs, one patient developed a contained rupture while 2 patients were completely asymptomatic. However, all patients were hemodynamically stable at the time of treatment. Technical success was defined as immediate complete exclusion of the aneurysmal sac, and clinical success as complete relief from clinical symptoms. Follow-up was performed with CT angiography, ultrasound and clinical examination. Mean follow-up was 45 months (range 6–84). Technical and clinical success were both 91%. Complications were one lack of control of contained rupture that was subsequently operated, one case of self-limiting non-target spleen embolization and one case of splenic abscess. Three patients died, one due to the contained rupture 15 days after procedure, the other two for other causes and occurred during the long-term follow-up. This series suggests that endovascular treatment of giant visceral artery aneurysms and pseudoaneuryms is a valid minimally invasive solution with very satisfactory immediate and long-term outcomes unless the aneurysm is already ruptured. A variety of endovascular tools may be required for successful treatment.

Life Threatening

Background: With estimated prevalence of 1% of the general population, visceral artery aneurysms are not a frequent pathology, however, their rupture is a life-threatening occurrence with mortality rate ranging from 10% to 25%, up to 75% in case of pregnant women. Therefore, the identification and treatment of visceral artery aneurysms is of great importance in the prevention of early rupture. Purpose: To assess the effectiveness and safety of treatment of visceral artery aneurysms with various endovascular methods focusing on technical aspects, complications and long-term clinical outcome. Materials and Methods: 60 patients with visceral artery aneurysms were treated percutaneously. Various techniques were used: coiling (23), covered stents (15), thrombin (7), and other mixed techniques. Aneurysm characteristics, size and localization, procedural data, peri-procedural complications, technical success, 90- and 180-day clinical success and follow-up period (aneurysm exclusion, patency of the artery and complications) were prospectively analyzed. Results: Te procedure was performed in 57 of 60 patients. In 56 of 57 patients aneurysms ware effectively excluded. Te success rate was 93.3% (56 of 60 enrolled patients). Technical success after the intervention was 82.4%, after second 98.2%. Embolization with covered stents ware characterized by highest efficiency. Serious complications occurred in 1.8% of cases. Conclusions. The minimally invasive endovascular treatment of visceral artery aneurysms is characterized by high efficacy and safety. Good treatment results depend on proper assessment of the aneurysm’s morphology as well as on selection of the appropriate vascular approach and endovascular technique.

Purpose To evaluate the safety and efficacy of transbrachial and transfemoral approaches combined with visceral protection for the endovascular treatment of juxtarenal aortoiliac occlusive disease (AIOD) over an average 19-month follow-up period. Methods In this retrospective analysis, all patients with juxtarenal AIOD at a single institution were reviewed from June 2015 to January 2020. Patient characteristics, angiographic results, and follow-up outcomes were retrospectively recorded. The indications for treatment were critical limb threatening ischemia in 12 patients and bilateral claudication in five patients. Percutaneous access via the left brachial artery was first obtained to recanalize the infrarenal occluded lesions. After that, femoral accesses were achieved. A 4-Fr catheter, a 4 mm balloon, or a 6-Fr 90-cm-long sheath was used to complete visceral artery protection. Results A total of 17 juxtarenal AIOD patients (14 males; mean age, 63.4 ± 8.1 years) underwent endovascular treatment. The technical success rate was 100%. Complete reconstruction was achieved in 15 (88.2%) patients. The infrarenal aorta was reconstructed with kissing covered stent grafts ( n = 7), kissing bare-metal stents ( n = 2), covered stent grafts ( n = 2), bare-metal stents ( n = 1), or the off-label use of iliac limb stent grafts ( n = 5). Renal embolization was found in 3 (17.6%) patients during intraoperative angiography. There was 1 (5.9%) case of distal runoff embolization after CDT and 1 (5.9%) case of left iliac artery rupture. One (5.9%) death occurred due to acute myocardial infarction 20 days after the operation. The average follow-up period was 19.3 ± 16.7 months (range, 1–54 months) in the remaining 16 cases. The renal artery patency rate was 100%. The estimated cumulative primary patency rates were 92.3% at 12 months and 59.3% at 36 months according to the Kaplan–Meier method. Conclusions Transbrachial and transfemoral approaches combined with visceral protection offer a safe and effective alternative to open revascularization for the endovascular treatment of juxtarenal AIOD.

Purpose: To review a single-center experience with fenestrated and branched endovascular aneurysm repair (f/bEVAR) in patients with challenging iliac anatomies. Materials and Methods: A retrospective review of the department’s database identified 398 consecutive patients who underwent complex endovascular repair f/bEVAR between January 2010 and June 2018; of these, 67 had challenging accesses. The strategies implemented to overcome access issues were reviewed, using a dedicated scoring system to evaluate the access (integrating diameter, tortuosity, calcification, and previous open or endovascular repair). Results: In this subgroup of patients, the most common graft design was a 4-vessel fenestrated endograft (27, 40.3%). Hostile access was due to small diameter (<7 mm) in 25 patients (37.3%) and/or concentric calcifications in 19 patients (26.9%). Mean iliac diameter was 5.5±2.6 mm on the right side and 6.0±2.5 mm on the left side. Previous open or endovascular aortoiliac repair had been performed in 15 patients (22.4%), and 20 patients (29.9%) had a stent previously implanted in at least 1 iliac artery, resulting in the inability to perform standard fenestrated repair with access from both sides. Five patients (7.5%) had a single patent iliac access. Eight distinctive strategies were identified to overcome these access issues, including the use of preloaded renal catheters in the endograft delivery system, angioplasty, graft modification (branches instead of fenestrations or 4 preloaded fenestrations), a conduit via a retroperitoneal approach, iliac artery recanalization, and/or the multiple puncture technique. Technical success was achieved in 62 cases (92.5%). Four patients had access complications and 1 died in the early postoperative period of multiorgan failure. Median follow-up was 24.6 months (IQR 7.2, 41.3). Clinical success at the end of follow-up was achieved in 57 patients (85.1%). During follow-up, 14 patients died, including 4 from an aorta-related cause. Conclusion: Dedicated strategies can be implemented to overcome hostile iliac access in patients with complex aneurysms when f/bEVAR is required. Typically, these maneuvers are associated with favorable outcomes.

Abstract Purpose Visceral artery aneurysms are subdivided into true aneurysms and pseudoaneurysms. Visceral artery pseudoaneurysms (VAPAs) are uncommon in clinical practice but may have serious clinical outcomes up to death. Endovascular management is a safe effective alternative option to traditional surgical procedures. This study assesses the outcome of different embolic materials and techniques used in the endovascular management of visceral artery pseudoaneurysms. Materials and methods This is a multicentric prospective analysis of endovascular embolisation of 46 VAPAs with a mean pseudoaneurysm size of 13 ± 11.35 mm. Management using coils only was done in 28/46 patients (60.87%), NBCA glue only in 16/46 patients (34.78%), combined coils and NBCA glue in 1/46 patient (2.17%), and Amplatzer plugs only in 1 patient (2.17%). The management techniques were sac packing in 9/46 patients (19.57%), inflow occlusion in 28/46 patients (60.87%) and trapping in 9/46 patients (19.57%). Results The overall clinical success rate was 93.48%, the overall perioperative complication rate was 15.22% and 30-day mortality was zero. For the coil subgroup (n = 28), the clinical success was 92.86%, while the subgroup of NBCA glue (n = 16) showed clinical success of 93.75%. There was no significant statistical difference between clinical success among coil, and NBCA glue subgroups (P > 0.05). The technical success rate was 100%. Effectiveness of the procedures during the follow-up was 97.83%. Target lesion re-intervention rate was 2.17%. Conclusion Transarterial embolisation can provide high technical and clinical success rates with low perioperative complication and re-intervention rates, as well as satisfactory procedure effectiveness in the management of VAPAs.

Purpose: To report a case of paradoxical emboli to multiple visceral vessels treated with both mechanical (AngioJet device) and pharmacological (urokinase) thrombolysis. Methods and Results: A 72-year-old man presented with a 48-hour history of symptomatic right renal ischemia, which was treated with heparinization. Five days later, an abrupt creatinine elevation prompted arteriography, which demonstrated thromboembolism of the superior mesenteric artery (SMA) and both renal arteries. The AngioJet aspiration device was employed to successfully remove the clot from the SMA; urokinase infusion restored flow to the left kidney. At the 16-month follow-up evaluation, the patient was normotensive without medication and had a stable creatinine (1.4 mg/dL). Conclusions: Because of its speed and minimal morbidity, the AngioJet device may be an attractive alternative to surgical embolectomy or pharmacological thrombolysis in highly selected cases of acute visceral artery thromboembolism.
