“…The aberrant obturator artery (AOA) is a common arterial variant that occurs in more than half of the population and, if present in pelvic fractured patients, is commonly injured. 25 , 26 Thirdly, pre-injury medical conditions, such as anticoagulation treatment, are risk factors for external iliac artery injury. 24 Lastly, direct violence to the groin region as reported in the current study is a high risk factor for injury of the external iliac artery and its branches.…”

PurposeTo enhance the awareness of rare complications of pelvic fracture and describe the correct diagnosis and effective treatment.MethodsA total of 188 cases of pelvic fractures were retrospectively reviewed, and four patients who suffered from four types of rare pelvic fracture complications were described, namely ureteral obstruction caused by retroperitoneal hematoma-induced abdominal compartment syndrome (ACS), bowel entrapment, external iliac artery injury, and open scrotal sac injury.ResultsWe demonstrated that combined measures should be employed to prevent the occurrence of ACS following major pelvic fractures. Ureteral catheter support may be a good option at an early stage when ACS occurred. Contrasted computed tomography examination and sufficient awareness are keys to a correct diagnosis of bowel entrapment following pelvic fractures. Recognition of risk factors, early diagnosis, and prompt treatment of suspected injury of the external iliac artery are keys to patient survival and to avoid limb loss. Scrotal and/or testicular injury complicated by pelvic fractures should be carefully treated to maintain normal gonad function. Additionally, establishment of a sophisticated trauma care system and multi-disciplinary coordination are important for correct diagnosis and treatment of rare complications in pelvic fractures.ConclusionsRare complications of pelvic fractures are difficult to diagnose and negatively impact outcome. Recognition of risk factors and sufficient awareness are essential for correct diagnosis and prompt treatment.

“…We searched for such case reports through PubMed using the keywords “corona mortis,” “aberrant obturator artery,” “pelvic pseudoaneurysm,” and “pubic ramus fracture” with no date limits but with English-language restriction. However, there are few cases of pubic ramus fracture requiring such embolization reported in the literature to date [ 3 , [10] , [11] , [12] , [13] , [14] , [15] ].…”

“…Blood vessels in the pelvis may present with various anastomoses; an anastomosis occurring between the external and internal iliac systems is known as corona mortis (crown of death) and may cause uncontrolled bleeding [3] . The prevalence of arterial corona mortis ranges from 17%-45% [4] , [5] , [6] , [7] , [8] , [9] , but few cases of bleeding in the corona mortis artery require embolization of the external and internal iliac systems [ 3 , [10] , [11] , [12] , [13] , [14] , [15] ]. An aberrant obturator artery arising from the medial femoral circumflex artery is extremely rare, with an estimated prevalence of <0.43% [17] , and it may complicate arterial embolization.…”

“…An aberrant anastomotic connection between the obturator artery and the inferior epigastric artery is known as the corona mortis (Fig 9) (Movie 6). It is the most important anatomic variation and is present in up to 30% of patients (43)(44)(45). The corona mortis should be considered as a bleeding source if the internal iliac angiogram does not reveal a pelvic source of the bleeding at digital subtraction angiography (DSA).…”

Pelvic vascular injuries are typically caused by high-energy trauma. The majority of these injuries are caused by motor vehicle collisions, and the rest are caused by falls and industrial or crush injuries. Pelvic vascular injuries are frequently associated with pelvic ring disruption and have a high mortality rate due to shock as a result of pelvic bleeding. Morbidity and mortality resulting from pelvic vascular injury are due to pelvic hemorrhage and resultant exsanguination, which is potentially treatable and reversible if it is diagnosed early with multidetector CT and treated promptly. The pelvic bleeding source can be arterial, venous, or osseous, and differentiating an arterial (high-pressure) bleed from a venous-osseous (low-pressure) bleed is of paramount importance in stratification for treatment. Low-pressure venous and osseous bleeds are initially treated with a pelvic binder or external fixation, while high-pressure arterial bleeds require angioembolization or surgical pelvic packing. Definitive treatment of the pelvic ring disruption includes open or closed reduction and internal fixation. Multidetector CT is important in the trauma setting to assess and characterize pelvic vascular injuries with multiphasic acquisition in the arterial and venous phases, which allows differentiation of the common vascular injury patterns. This article reviews the anatomy of the pelvic vessels and the pelvic vascular territory; discusses the multidetector CT protocols used in diagnosis and characterization of pelvic vascular injury; and describes the spectrum of pelvic vascular injuries, the differentiation of common injury patterns, mimics, and imaging pitfalls.
