Isolated common iliac artery dissection and aneurysm

Abstract

DESCRIPTIONA 49-year-old man, with a history of well-controlled hypertension, presented with sudden left lower quadrant abdominal pain after defaecation. The severity of the pain was scaled as 1-2 over 10 and the pain was continuous. There were no digestive symptoms. On admission, vital signs were as follows: blood pressure 130/70 mm Hg, pulse rate 70 bpm, respiratory rate 18 breaths/min, SpO 2 97% and body temperature 37.4°C. On physical examination, the abdomen was soft and flat and the bowel sound was normal. There was tenderness on the left side of the umbilicus. Neither rebound nor guarding was noted. Pulses in the peripheral arteries were well palpable and equal. There were no specific signs suggestive of any connective tissue diseases such as Marfan syndrome. Laboratory data were within normal limits. Contrast-enhanced CT revealed a dissection and aneurysm formation in the left common iliac artery (figure 1). The patient was diagnosed as having isolated left common iliac artery dissection.Isolated common iliac artery dissection is a very rare disease; we are aware of only a few case reports. In those articles, the possible causes included atherosclerosis, fibromuscular dysplasia, connective tissue disease, trauma and pregnancy.

Effectiveness of the conservative therapy for spontaneous isolated iliac artery dissection: Preliminary results

“…Although multiple case reports have been performed previously in patients with SIIAD, 5,11–15 the underlying causes and etiology of SIIAD are still unclear. 12–16 According to this study, SIIAD occurred in 90.9% male patients with the mean age of 71.1 ± 7.8 years, 63.6% patients have been smoking, and 45.5% patients have hypertension. Previous reports have also identified several risk factors for SIIAD, including atherosclerosis, vascular type Ehlers–Danlos syndrome, fibromuscular dysplasia, cystic medial degeneration Erdheime–Gsell.…”

“…Previous reports have also identified several risk factors for SIIAD, including atherosclerosis, vascular type Ehlers–Danlos syndrome, fibromuscular dysplasia, cystic medial degeneration Erdheime–Gsell. 5,11–15 Although 11 patients were included in this study, there was no patient was approved with vascular type Ehlers–Danlos syndrome, fibromuscular dysplasia, cystic medial degeneration Erdheime–Gsell. The statistical analysis of potential risk factors was not possible in our study because of the small sample size.…”

Acute onset of lower limb claudication as a manifestation of a spontaneous common iliac artery dissection

“…Ehlers-Danlos syndrome (type IV), Marfan syndrome, Loeys-Dietz syndrome, Lukasz Hapka, Grzegorz Halena, Acute onset of lower limb claudication as a manifestation of a spontaneous CIA dissection fibro-muscular dysplasia [8,9] are all examples of such genetic mutations.…”
