Midterm Results of a Surgeon-Modified Device to Preserve the Flow of the Internal Iliac Artery During Endovascular Repair of Aneurysm: Single-Center Experiences. Ann Vasc Surg 2023; 91:117-126. [PMID: 36503023 DOI: 10.1016/j.avsg.2022.11.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Revised: 10/24/2022] [Accepted: 11/06/2022] [Indexed: 12/13/2022]
Abstract
BACKGROUND During endovascular aneurysm repair (EVAR), commercial iliac branch devices (IBDs) have become an inescapable alternative for preserving antegrade internal iliac artery (IIA) blood flow. Due to the different morphological features of aneurysms, commercial IBDs may not be suitable for all patients. Reported experience with the implantation of the new surgeon-modified IBD (sm IBD) is limited. This investigation describes the indications, efficacy, and safety of the sm IBD. METHODS Data from consecutive elective implantations of IBDs in patients between March 2011 and May 2021 in a single center were incorporated. The sm IBDs were indicated in patients with common iliac artery aneurysms (CIAAs) and with a challenging anatomy and in those patients with or without abdominal aortic aneurysm (AAA). RESULTS Fifteen patients (15 male, mean age 67.6 ± 7.9 years) were included. Fifteen sm IBDs were implanted in 1 procedure (100%). Fourteen (93.3%) patients had simultaneous endovascular aneurysm repair (EVAR) and 1 (6.7%) patient previously had a bilateral CIAAs repair by EVAR. The mean common iliac artery (CIA) diameter was 36.6 ± 12.5 mm. Technical success was obtained in all patients (100%). The median operation time was 189.7 ± 78.6 min, with a median fluoroscopy time of 45.3 ± 15.9 min. Axillary artery access was used in 11 (73.3%) procedures. The mean total hospital stay was 5.6 ± 2.8 days, and the postoperative follow-up was 35.4 months (range 2-120). The estimated IIA bridge stent patency at 1 year after operation was 100% and 85.7% ± 13.2% 5 years postoperatively. One (6.7%) IIA branch was occluded, and this patient remained asymptomatic. One patient (6.7%) needed reintervention, and another (6.7%) patient had type II leakage, which is currently under close surveillance. CONCLUSIONS Using an IBD to maintain the pelvic blood flow is an effective and feasible intravascular technique, especially for patients with an abnormal iliac artery anatomy. This novel technique has similar midterm procedural success rate compared to the use of commercial IBDs. Therefore, these devices are more suitable for patients with certain anatomic challenges and can be used as an alternative treatment.

Abstract
Objective: The combination of isolated common and internal iliac artery aneurysms (CIIAA) are rare, life-threatening, abnormal conditions with relatively complex treatment. This study aimed to evaluate the clinical characteristics and treatment outcomes of CIIAA. Methods: We retrospectively reviewed 26 patients with CIIAA consecutively treated between January 2010 and August 2020 at Peking Union Medical College Hospital. Demographic, clinical characteristic, treatment strategy and outcome data were collected and analyzed. Results: Twenty-six patients (24 men and 2 women) with a mean age of 70 years were included. There was a total of 72 aneurysms, and the mean diameters of the common iliac artery aneurysms (CIAA) and internal iliac artery aneurysms (IIAA) were 36 and 38 mm, respectively. Ten patients (38%) presented with bilateral CIAA and unilateral IIAA, and eight (31%) had CIAA with ipsilateral IIAA. All patients were treated with endovascular repair, and the overall primary technical success rate was 100%. The surgical techniques mainly included combined bifurcated stent grafting and embolization (n = 11), combined straight stent grafting and embolization (n = 8), and internal iliac artery (IIA) reconstruction (n = 7). There were no patient deaths or reintervention during hospitalization. The mean follow-up time was 43 months, and the patency rate of the stent was 96.2%. The overall reintervention rate was 7.7%. During the follow-up period, there were no aneurysm-related deaths. Conclusions: Endovascular repair involving stent graft placement, coil embolization and IIA revascularization is a safe and effective treatment for isolated CIIAA.

Morphology-Related Limitations of Endovascular Aneurysm Repair Applicability in the Treatment of Abdominal Aortic Aneurysm in West-Central Poland. Ann Vasc Surg 2018; 52:49-56. [PMID: 29772324 DOI: 10.1016/j.avsg.2018.02.032] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2017] [Revised: 02/12/2018] [Accepted: 02/28/2018] [Indexed: 12/20/2022]
Abstract
BACKGROUND Morphology is one of the most important factors influencing the long-term durability of endovascular repair of an infrarenal abdominal aortic aneurysm (AAA). The knowledge of morphological characteristics of AAA that may differ in various populations seems to be important for further development of a technology of endovascular repair as well as for planning of treatment strategies. To analyze the current applicability of endovascular aneurysm repair (EVAR) in patients with an infrarenal AAA with an indication for elective treatment in west-central Poland. METHODS Computed tomography angiograms of 100 consecutive patients with infrarenal AAA deemed to require treatment were analyzed with an OsiriX DICOM viewer in 3D-multiplanar reconstruction mode. Proximal neck diameter, length, angulation, shape, the presence of thrombus and calcification, distal neck diameter, and morphology of the iliac arteries were determined. Three sets of morphological criteria were established. The optimal criteria consisted of a nonconical proximal neck without moderate or severe calcification or thrombus, with a diameter of 18-28 mm, length of ≥15 mm, and β angulation of <60%; a distal neck with a diameter of ≥20 mm; a landing zone in the common iliac arteries (CIAs) with a length of ≥10 mm and diameter of ≤20 mm; and external iliac arteries with diameters of ≥7 mm. The suboptimal criteria included proximal neck diameters of 18-32 mm, neck lengths ≥10 mm, infrarenal neck angulations of up to 75°, and CIA diameters of up to 25 mm. Finally, the extended suboptimal criteria included proximal neck diameters of 16-34 mm and infrarenal neck angulations ≤90°, without limits in the maximal diameter of the CIAs. RESULTS The median maximum aneurysm diameter was 61 mm. The optimal, suboptimal, and extended suboptimal criteria were met by 23%, 32%, and 53% of patients, respectively. The most common deviations were wide, conical, and angulated proximal necks and aneurysmal iliac arteries. CONCLUSIONS The majority of patients with AAA deemed to be candidates for elective repair do not meet the most favorable criteria for EVAR. Availability of better endovascular solutions for conical, angulated, and wide necks and aneurysmal iliac arteries would likely expand EVAR applicability. Open repair remains a valid option.

Hybrid Endovascular Aortic Aneurysm Repair: Preservation of Pelvic Perfusion with External to Internal Iliac Artery Bypass. Ann Vasc Surg 2017; 42:162-168.

Abstract
BACKGROUND Diminished pelvic arterial flow as a result of intentional coverage/embolization of internal iliac arteries (IIA) during isolated endovascular common iliac artery aneurysm (CIAA) repair or endovascular repair of abdominal aortic aneurysms (EVAR) may result in symptomatic pelvic ischemia. Although generally well tolerated, in severe cases, pelvic ischemia may manifest as recalcitrant buttock claudication, vasculogenic impotence, or perineal, vesicle, rectal, and/or spinal cord ischemia. Branched graft technology has recently become available; however, many patients are not candidates for endovascular repair with these devices. Therefore, techniques to preserve pelvic arterial flow are needed. We reviewed our outcomes of isolated endovascular CIAA repair or EVAR in conjunction with unilateral external-internal iliac artery bypass. METHODS Single-center, retrospective review of 10 consecutive patients who underwent hybrid endovascular abdominal aortic aneurysm (AAA) or CIAA repair with concomitant external-internal iliac artery bypass between 2006 and 2015. Demographics, index procedural details, postoperative symptoms, hospital length of stay (LOS), follow-up imaging, and bypass patency were recorded. RESULTS The cohort of 10 patients was all men with a mean age of 71 years (range: 56-84). Hybrid repair consisted of contralateral IIA coil embolization followed by EVAR with external iliac artery-internal iliac artery (EIA-IIA) bypass. All EIA-IIA bypasses were performed via a standard lower quadrant retroperitoneal approach with a prosthetic bypass graft. Technical success was 100%, and there were no perioperative deaths. One patient developed transient paraplegia, 1 patient had buttock claudication on the side of his hypogastric embolization contralateral to his iliac bypass, and 1 developed postoperative impotence. 20% of patients sustained long-term complications (buttock claudication and postoperative impotence). Mean LOS was 2.8 days (range: 1-9 days). Postoperative imaging was obtained in 90% of patients, and mean follow-up was 10.8 months (range: 0.5-36 months). All bypasses remained patent. CONCLUSIONS Although branched graft technology continues to evolve, strategies to maintain adequate pelvic circulation are necessary to avoid the devastating complications of pelvic ischemia. We have demonstrated that a hybrid approach combining EVAR or isolated endovascular common iliac artery exclusion with a unilateral external-internal iliac bypass via a retroperitoneal approach is well tolerated with a short LOS and excellent patency rates.

Outcome after Interruption or Preservation of Internal Iliac Artery Flow During Endovascular Repair of Abdominal Aorto-iliac Aneurysms. Eur J Vasc Endovasc Surg 2016; 52:621-634. [PMID: 27600731 DOI: 10.1016/j.ejvs.2016.07.081] [Citation(s) in RCA: 89] [Impact Index Per Article: 11.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2016] [Accepted: 07/19/2016] [Indexed: 11/25/2022]
Abstract
AIM The aim was to conduct a systematic review of the literature investigating outcomes after interruption or preservation of the internal iliac artery (IIA) during endovascular aneurysm repair (EVAR). METHODS A systematic review was undertaken using the MEDLINE and EMBASE databases to identify studies reporting IIA management during EVAR. The search identified 57 articles: 30 reported on IIA interruption (1468 patients) and 27 on IIA preservation (816 patients). RESULTS The pooled 30 day buttock claudication (BC) rate was 29.2% (95% CI 24.2-34.7). Patients undergoing bilateral IIA interruption had a higher incidence of BC than patients with unilateral IIA interruption (36.5% vs. 27.2%, OR 1.7, 95% CI 1.11-2.6, p = .01). During a median follow up of 17 months, the pooled rate of persistent BC was 20.5% (95% CI 15.7-26.2). Of the patients, 93.9% underwent an endovascular revascularization procedure for IIA preservation. Most patients (87.6%) had an iliac branched device, and technical success was 96.2%. Within 30 days of EVAR, 4.3% of internal iliac branches occluded. During a median follow up of 15 months, the pooled occlusion rate at the site of IIA revascularization was 8.8% (95% CI 6.8-11.3). In patients treated with an iliac-branched device, 5.2% of internal iliac branches and 1.7% of external iliac arteries occluded. The pooled BC rate on the side of the IIA revascularization during follow up was 4.1% (95% CI 2.9-5.9). Pooled rates of late device related endoleak type I or III and secondary procedures on the side of the previous IIA revascularization were 4.6% (95% CI 3.2-6.5) and 7.8% (95% CI 5.7-10.7) respectively. CONCLUSION Unilateral or bilateral IIA occlusion during EVAR seems to carry a substantial risk of significant ischemic complications in nearly one quarter of patients. Bilateral IIA occlusion was related to a significantly higher rate of BC. IIA preservation techniques represent a significant improvement in the treatment of aorto-iliac aneurysms and have been associated with high technical success and low morbidity.
