Arteropathies, Microcirculation and Vasculitis
Published in Mary N. Sheppard, Practical Cardiovascular Pathology, 2022
Endofibrosis is a rare disease affecting mainly highly trained cyclists. However, it is now found in many other endurance athletes of both genders. Exercise-induced arterial endofibrosis was first described in competitive cyclists in 1985. It was previously known as ‘external iliac artery endofibrosis’ as this was affected in 90% of the cases.9 The term was changed later since other locations were affected such as the common iliac artery, the common femoral artery, the profunda femoris and quadricipital artery. It consists of intraluminal nonatheromatous fibrous thickening and is due to repeated trauma associated with vigorous exercise. The internal elastic membrane, media and adventitia are usually normal, but the elastic membrane may be duplicated. It is now treated primarily with drug-coated balloon angioplasty.9

Repair of isolated iliac artery aneurysms was traditionally performed with open surgery. However, advances in endovascular technology have allowed for more minimally invasive options, avoiding the challenges of operating deep within the pelvis. Hybrid procedures, including both open and endovascular components, can be used as well. The most appropriate mode of repair should consider the extent and distribution of aneurysmal disease and patient characteristics in order to develop a suitable operative plan (Figure 18.1).5,11
Placement of Balloon-Expandable Intraluminal Stents in Iliac Arteries: First 171 Procedures

Inclusion/Exclusion Criteria Indications for stent placement were inadequate immediate post-angioplasty response, restenosis after prior iliac balloon angioplasty, and total iliac artery occlusion. Contraindications to stent placement were extravasation of contrast after initial balloon angioplasty, marked tortuosity of the iliac arteries, and dense, extensive arterial calcification. Additional relative contraindications included concomitant iliac artery aneurysms, severe hypertension, impaired pain sensation, stenosis of the common femoral artery, and poor distal arterial outflow.

Twelve months later, the patient was readmitted to our unit following intermittent claudication. During that time he still suffered from the loss of consciousness, but notably the frequency was decreasing. Then the ultrasound examination revealed a severe stenosis of the right common iliac artery. DSA confirmed the stenosis of at least 80%, and a stent was successfully implanted. In this process, we also rechecked the left vertebral artery. Although the stenosis still exist, another collateral circulation involving thyrocervical trunk was found supplying flow to the left vertebral artery (V3 segment) (Figure 3a, b). Furthermore, the collateral circulation fed by external carotid collateral branches (occipital artery) was constructed more better than before (Figure 3c). In this process, the frequency of loss of consciousness gradually decreased with the collateral circulation construction.
Profile of the Ovation ALTO abdominal stent graft for the treatment of abdominal aortic aneurysms: overview of its safety and efficacy

The Ovation iX and Ovation ALTO endografts comprise of a Nitinol stent, responsible for supra-renal fixation and polymer injected fabric more inferiorly, responsible for sealing of the aneurysm sac. The separation of the endografts’ stent and the polymer-injected fabric allows the device to fit within a low profile sheath, with an outer diameter of 15 French [31]. A study of one-year outcomes following treatment with the Ovation iX device included 50 patients with maximum iliac diameter of less than 6 mm and achieved 100% treatment success [35]. A larger five-year follow up study of 1296 patients included a further 231 patients with iliac artery diameters of less than 6 mm [36]. The study reported high rates of percutaneous access (69% of female patients and 63% male patients), with a low incidence of access site complications (7.2% of female patients, 3.7% male patients). The authors of both studies suggest that the Ovation iX device has the potential to increase overall patient eligibility with regard to iliac access up to 90% for men and 70% for women; basing their assessment on data extrapolated from Sweet et al.’s regression analysis of iliac artery diameter [35,36].

The majority of the complications listed in Table 3 occurred due to partial or complete coverage of a visceral aortic branch by the endograft, or limb occlusion. There were four reported cases of acute limb ischemia, requiring intervention, of which three were within 2 days of the primary procedure [12,13], and the fourth patient presented on day 14 post procedure due to endograft limb occlusion [16]. Internal iliac artery occlusion reported in 12 patients (planned in one only) had mild buttock claudication symptoms and required no intervention. One author reports an ipsilateral external iliac artery occlusion occurring due to damage from the delivery system [7]. There were two reported cases of bowel ischemia, one managed conservatively [13], and the other patient died due to bowel infarction found on laparotomy [12]. Out of the four patients reported to have renal impairment, only one required renal artery stenting [13], but none of them required any renal support.
