Project description:We present a case of a 30-year-old female professional cyclist who presented with right thigh claudication while performing high-intensity efforts. Based on the typical clinical history and the presence of a smooth long segment diffuse narrowing in the right external iliac artery on non-contrast magnetic resonance angiography, a diagnosis of external iliac artery endofibrosis or "cyclist's iliac syndrome" was made.Supplementary informationThe online version contains supplementary material available at 10.1007/s12055-022-01349-8.

Project description:IntroductionIsolated iliac artery dissection (IAD) is a rare form of arterial dissection. The most commonly known causes of non-traumatic isolated iliac dissection are connective tissue diseases. Relapsing polychondritis (RP) is a rare inflammatory and multisystemic disease, typically affecting cartilage and connective tissue. Cardiovascular complications occur in approximately 25% of patients with RP.Case descriptionThe first case of spontaneous isolated bilateral iliac artery dissection in a patient with RP is reported. A 48-year-old woman presented with a two year history of severe right leg intermittent claudication (Rutherford category 3). The complaints were initially attributed to joint pathology associated with RP. However, clinical examination and computed tomography angiography led to a diagnosis of bilateral IAD. A dissection in the left common iliac artery (CIA) began at its origin and ended at the origin of the internal iliac artery, with the true and false lumen both comprising half of the entire lumen. The right CIA was completely occluded from its origin to the origin of the right internal iliac artery. The patient was treated endovascularly by bilateral CIA stent placement with covered stent grafts (Bentley BeGraft), 8 × 57 mm on the right side and 8 × 37 mm on the left. The patient recovered pedal pulses, the stent remained patent, and the patient was asymptomatic at the one month follow-up.DiscussionEarly identification of intermittent claudication is necessary to prevent the progression of complications in patients with RP. Vascular surgeons should be aware of IAD as the potential first presentation of underlying systemic disease. Internists should also keep vascular complications in mind in patients with systemic diseases like RP suffering from unexplained complaints in the lower limbs, undertake a basic vascular examination, and make a vascular referral where appropriate.

Project description:This report describes DeBakey Type I aortic dissection in a middle-aged hypertensive female who had undergone mitral tissue valve replacement a decade previously. The patient had severe abrupt onset tearing pain in her throat, back, and chest, for which she got admitted in a community hospital, where because of no changes in her ECG and biomarkers, the dissection of aorta was missed. She was subjected to coronary angiography more than 6 weeks later for pain in her left shoulder, which demonstrated normal vessels. She then underwent multi-detector computerised tomography aortogram (MD CTA) that revealed aortic dissection involving ascending, the arch, and descending thoracic and abdominal aorta. The patient declined surgical intervention and has been provided medical therapy in the form of high dose oral beta-blocker and losartan. The patient continues to be stable for the past 18 weeks since the index event. The report highlights the importance of detecting aortic dissection by keeping high index of clinical suspicion in a patient with abrupt onset tearing pain in the throat/back and employment of MD CTA.

Project description:ObjectivesVertebrobasilar stenosis is frequent in patients with posterior circulation stroke and it increases risk of recurrence. We investigated feasibility of duplex ultrasonography (DUS) for screening for extracranial vertebral artery stenosis and compared it with CT angiography (CTA).Materials and methodsWe gathered data on 337 consecutive patients who had DUS because of posterior circulation stroke or TIA. Matching CTA studies were retrieved and used as reference. Stenosis on CTA was considered "significant" if >50%, at DUS if Peak Systolic Velocity (PSV) > 140 cm/s for the V1 segment and PSV > 125 cm/s for the V2 segment. We determined the area under the ROC curve (AUROC). In addition, we calculated which PSV cut-off value resulted in highest sensitivity with acceptable specificity.ResultsDUS was able to make an adequate measurement in 378 of 674 V1 segments and 673 of 674 V2 segments. DUS detected a significant stenosis in 52 of 378 V1 segments; 12 were confirmed by CTA (AUROC 0.73, 95% Confidence Interval 0.63-0.83). The optimal DUS PSV cut-off value for this segment was 90 cm/s. For the V2 segment there were too few stenoses to allow reliable assessment of diagnostic characteristics of DUS.ConclusionsAlthough DUS has a fair AUROC for detecting significant stenosis, adequate assessment of the V1 segment is often not possible due to anatomic difficulties. Assessment of the V2 segment is feasible but yielded few stenoses. Hence, we consider usefulness of DUS for screening of extracranial vertebral artery stenosis limited.

Project description:A 64-year-old man with a history of right external iliac artery stenosis after stenting with a self-expandable stent was admitted for repetitive in-stent restenosis (ISR). To treat ISR, we selected a balloon expandable stent (BES) that was prepared with negative suction before being inserted into the sheath. BES dislodged when the stent balloon was incompletely inflated and was simultaneously deformed in a funnel shape. When BES was retrieved using a short noncompliant balloon, it dislodged again because of an imbalanced proximal inflation of the balloon. We finally retrieved BES using a long noncompliant balloon and deployed it with dog-bone inflation without any additional devices. <Learning objective: To report an easy method for retrieving and redeploying a deformed, dislodged stent without using an additional device. Retrieving a relatively large peripheral stent that becomes deformed and dislodged is difficult and may require surgery. Balloon catheter retrieval is a useful strategy to salvage and redeploy the dislodged stent. However, a large size short noncompliant balloon catheter had the risk for dislodging the retrieved deformed stent again. To retrieve and salvage a deformed and dislodged stent, a long balloon and dog-bone inflation may be useful.>.

Project description: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.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.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.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.

Project description:Bilateral absence of the common iliac artery is an extremely rare congenital vascular malformation in which the distal aorta divides directly into two external iliac arteries and two internal iliac arteries. In the case of the presence of this vascular malformation in association with an aortic aneurysm, preservation of the internal iliac artery flow during endovascular aortic repair represents a technical challenge. We have reported a case in which the bilateral absence of the common iliac artery associated with an infrarenal abdominal aortic aneurysm was successfully treated by endovascular aortic repair using commercially available iliac branched devices to maintain pelvic perfusion.

Project description:As vascular calcification is common in kidney transplant candidates, aorto-iliac vessel imaging is performed for surgical planning. The aim of the present study was to investigate whether a novel non-contrast enhanced computed tomography-based quantification technique for aorto-iliac calcification can be used for cardiovascular risk stratification prior to kidney transplantation. In this dual-center cohort study, we measured the aorto-iliac calcium score (CaScore) of 547 patients within three years prior to transplantation (2005-2018). During a median (interquartile range) follow-up of 3.1 (1.4, 5.2) years after transplantation, 80 (14.7%) patients died, of which 32 (40.0%) died due to cardiovascular causes, and 84 (15.5%) patients had a cardiovascular event. Kaplan-Meier survival curves showed significant differences between the CaScore tertiles for cumulative overall-survival (Log-rank test p < 0.0001), cardiovascular survival (p < 0.0001), and cardiovascular event-free survival (p < 0.001). In multivariable Cox regression, the aorto-iliac CaScore was associated with all-cause mortality (hazard ratio 1.53, 95%CI 1.14-2.06, p = 0.005), cardiovascular mortality (2.04, 1.20-3.45, p = 0.008), and cardiovascular events (1.35, 1.01-1.80, p = 0.042). These independent associations of the aorto-iliac CaScore with the outcome measures can improve the identification of patients at risk for (cardiovascular) death and those who could potentially benefit from stringent cardiovascular monitoring to improve their prognosis after transplantation.

Project description:Arterial calcification is associated with cardiovascular morbidity and mortality. To improve the understanding of the pathogenesis involved with iliac artery calcium (IAC), we sought to examine the associations between the burden of IAC with adiposity measures and peripheral artery disease (PAD). Participants (n = 1,236, 52% women, mean age 60 years) were drawn from the Framingham Heart Study Offspring cohort who underwent multidetector computed tomography. The extent of IAC was quantified based on calcified atherosclerotic plaques detected in the iliac arteries. High IAC was defined based on gender-specific 90th percentile cut-off points from a healthy referent subsample. PAD is defined as an ankle-brachial index < 0.9, intermittent claudication, and/or history of lower extremity revascularization. The association between PAD and IAC was assessed using multivariable-adjusted logistic regression models. The burden of high IAC was 20.5% in women and 25.5% in men. High IAC was not associated with generalized (body mass index) or area-specific (waist circumference, and volumes of thoracic periaortic, abdominal subcutaneous, and visceral adipose tissue) adiposity measures (all p ≥0.22). High IAC was associated with increased odds of PAD (odds ratio 10.36, 95% confidence interval 4.28 to 25.09). This association persisted even after additionally adjusting for coronary artery calcium (odds ratio 11.25, 95% confidence interval 4.29 to 29.53). Burden of IAC was associated with an increased risk of PAD.
