Massive haemorrhage after a low-energy pubic ramus fracture in a 71-year-old woman

Hypotension in the Emergency Department and Contrast Extravasation on Computerized Tomography Predict Blood Transfusion in Low-Energy Pelvic Fractures

INTRODUCTION

Although low-energy pelvic fractures seldom present with significant hemorrhage, early recognition of at-risk patients is essential. We aimed to identify predictors of transfusion requirements in this cohort.

METHODS

A 7-y retrospective chart review was performed. Low-energy mechanism was defined as falls of ≤5 feet. Fracture pattern was classified using the Orthopedic Trauma Association/Arbeitsgemeinschaft für Osteosynthesefragen system as A, B, or C. Primary outcome was transfusion of ≥2 units of packed red blood cells in the first 48 h. Univariable analysis and logistic regression analysis were performed. A P value ≤0.05 was considered significant.

RESULTS

Five hundred forty six patients were included with median (interquartile range) age of 86 (79-91) and median (interquartile range) Injury Severity Score of 5 (4-8). Five hundred forty one (99%) had type A fractures. Twenty six (5%) had the primary outcome and 17 (3%) died. Logistic regression found that systolic blood pressure <100 mmHg at any time in the Emergency Department, Injury Severity Score, and pelvic angiography were predictors of the primary outcome. Seventeen percent of those who had the primary outcome died compared with 2% who did not (P = 0.0004). Three hundred sixty four (67%) received intravenous contrast for computerized tomography scans and of these, 44 (12%) had contrast extravasation (CE). CE was associated with the primary outcome but not mortality.

CONCLUSIONS

Hypotension at any time in the Emergency Department and CE on computerized tomography predicted transfusion of ≥2 units packed red blood cells in the first 48 h in patients with low-energy pelvic fractures.

Can Nondisplacement Osteoporotic Pubic Rami Fracture Be Life-Threatening Injuries? A Case Report, Overview, and Algorithm Protocol for Management

Pubic rami fractures in the geriatric population are usually osteoporotic fractures resulting from low energy trauma and are characterized as stable injuries. Established treatment of these injuries is conservative, including rest, analgesic medication, and progressive active mobilization. These injuries are life-threatened when pubic rami fractures are accompanied by acute bleeding, either from an injury to a vessel (corona mortis) or from medication (anticoagulant or antiplatelet) for comorbidities, then. In this case study, we present the unusual case of an 82-year-old woman admitted to the emergency department 24 hours after a simple fall, causing nondisplacement osteoporotic pubic rami fracture, who, after 48 hours, developed a hematoma on the contralateral side of the pelvis, with progressive anemia and acute abdominal pain. This study has 2 objectives: to increase awareness of this life-threatening injury in the emergency department and to describe diagnosis and treatment modalities.

A Review on Management of Insufficiency Fractures of the Pelvis and Acetabulum

"Insufficiency fractures of the pelvis and acetabulum are occurring at increasing rates. Osteoporosis is the most prevalent risk fracture. Diagnosis begins with plain radiographs followed by advanced imaging with computed tomography and/or MRI. Pelvic ring fragility injuries are classified by the Fragility fractures of the pelvis system. Elderly acetabular fractures may be classified by the Letournel system. Management of these injuries is primarily nonoperative with early immobilization when allowed by fracture characteristics. When warranted, percutaneous fixation and open reduction internal fixation are options for both. Both acute and delayed total hip arthroplasty are options for acetabular fractures."

Post-surgical pseudoaneurysm of the corona mortis artery treated by arterial embolization from two arteries: A case report

Post-surgical pseudoaneurysm in the pelvis is rare. However, when it does occur, it may cause life-threatening hemorrhage. Hemostatic treatment for pelvic pseudoaneurysms may be complicated because the blood vessels in the pelvis may present with various anastomoses. Herein, we describe a case of a pseudoaneurysm that necessitated embolization of two arteries. A 47-year-old woman had undergone a total hysterectomy, a bilateral adnexectomy, and a pelvic lymphadenectomy for endometrial cancer; 13 days after surgery, she complained of sudden abdominal pain. Contrast-enhanced computed tomography revealed a retroperitoneal hematoma and a pseudoaneurysm with contrast leakage. The pseudoaneurysm had two feeding arteries (from the external and internal iliac systems). The first feeding artery was the obturator artery, which arose from the anterior trunk of the internal iliac artery. The second feeding artery was the aberrant obturator artery, which arose from the medial femoral circumflex artery. Both feeders were embolized and hemostasis was achieved. Pseudoaneurysms in the pelvis may have double origins from the external and internal iliac systems, and the aberrant obturator artery may arise from the medial femoral circumflex artery. Therefore, radiologists should be aware of these variations to effectively address post-surgical pseudoaneurysms of the corona mortis artery.

Bleeding Risk Associated With Hemodynamically Stable Low-Energy Pelvic Fracture

Introduction:

Life-threatening hemorrhage associated with low-energy pelvic fracture has been described in single cases in the literature. However, there is limited evidence available on the bleeding risk associated with hemodynamically stable osteoporotic pelvic fractures. The objective of this study was to estimate the bleeding risk associated with low-energy osteoporotic pelvic fractures in the elderly population.

Materials and Methods:

A retrospective review of patients aged > 65 years old with pelvic fractures admitted between 2015 and 2018 was performed. Eighty-two patients were identified: 12 males and 70 females with a median age of 86 years. The median Charlson comorbidity index was 6 (interquartile range = 5-7). Eighty-one fractures were classified as lateral compression I or Tile A2, and 1 fracture was classified as lateral compression II or Tile B2. Forty patients were on concurrent anticoagulation treatment. In 4 patients on warfarin, this treatment was reversed on admission.

Results:

The mean hemoglobin (Hb) level on arrival was 12.36 g/dL (±1.67 g/dL). There were significant drops in Hb levels on day 1 (Hb = 11.22 ± 1.86 g/dL, P < .001) and day 4 (Hb = 10.97 ± 1.6 g/dL, P < .001). Nine percent of patients required a blood transfusion. The mean baseline Hb level pre-transfusion was 8.33 g/dL (±1.15). Preexisting anticoagulation treatment did not predispose patients to greater decreases in Hb levels on day 1 (mean difference = 0.16 g/dL, P = .62) or day 4 (mean difference = 0.29 g/dL, P = .48) post-admission.

Discussion:

An observed mean decrease in Hb level of up to 1.4 g/dL can occur in hemodynamically stable elderly patients with osteoporotic pelvic fractures, reflecting an approximate loss of 1.4 units of packed red blood cells.

Conclusion:

This degree of decrease in Hb may be clinically significant in geriatric patients with chronic anemia and a history of cardiovascular disease.

Pelvic ring fractures in the elderly

Pelvic ring fractures are rare injuries in the elderly though the incidence is increasing due to the increasing age of the population.

Main goal of treatment is the quickest possible re-mobilization to prevent side-effects of immobilization such as osteopenia, pulmonary infections or thromboembolic events.

Isolated anterior pelvic ring fractures are stable injuries and therefore they usually can be treated conservatively, while pelvic ring injuries with involvement of the posterior ring are considered unstable and should undergo surgical stabilization if the patient’s condition allows for it.

Conservative treatment includes adequate analgesia, guided mobilization with partial weight bearing if possible and osteoanabolic medication.

The appropriate surgical procedure should be discussed in an interdisciplinary round considering patient’s pre-injury condition, anaesthetic and surgical risks.

The Role of Transcatheter Arterial Embolization in Traumatic Pelvic Hemorrhage: Not Only Pelvic Fracture

Purpose: The most common life-threatening complication of pelvic trauma is bleeding. Arterial bleedings frequently require active management, preferably with transcatheter arterial embolization (TAE). Hemodynamic instability and/or contrast extravasation at computer tomography (CT) examination are reliable indicators of arterial injury. Unstable pelvic fractures are much more hemorrhagic than stable fractures. Nevertheless, an absent or isolated pelvic fracture does not exclude pelvic hemorrhage.

Materials and Methods: A retrospective study was conducted on our institutional database by collecting data of patients who underwent pelvic angiography and/or embolization due to pelvic blunt trauma in the period between August 2010 and August 2015.

Results: In a period of five years, 39 patients with traumatic pelvic bleeding underwent angiography at our institution. Thirty-six of the 39 (92%) patients did show CT signs of active pelvic bleeding. Nineteen of 39 (49%) patients were hemodynamically unstable at presentation. Three of the 39 patients did not require embolization. Technical success was 35/36 (97%), and overall mortality was 3/39 (8%). Notably, 5/39 (13%) patients did not have any pelvic fracture at presentation, and 18/39 (46%) had only isolated or stable pelvic ring fracture.

Conclusions: TAE is an effective technique to treat arterial pelvic bleeding after trauma. The absence of a major pelvic fracture does not exclude the risk of active bleeding requiring prompt treatment.

Management of Life-Threatening Arterial Hemorrhage Following a Fragility Fracture of the Pelvis in the Anticoagulated Patient: Case Report and Review of the Literature

Background:

Life-threatening arterial bleeding from fragility fractures of the pelvis are very rare but associated with significant mortality, especially in anticoagulated patients.

Case Description:

We report the successful interdisciplinary management of a 78-year-old woman under anticoagulation and antiplatelet therapy who had life-threatening arterial hemorrhage from the pubic rami following a fragility fracture of the pelvis. Our management strategy included early hemorrhage control by means of selective arterial embolization followed by surgical fracture stabilization and surgical hematoma evacuation.

Literature Review:

We identified 6 cases within the English literature, all involving females older than 70 years. All patients under anticoagulation developed hemorrhagic shock, and in 2 cases selective embolization contributed to survival of the patient. However, a combined management including fracture stabilization and hematoma evacuation has not been reported, allowing an excellent clinical outcome and discharge to geriatric rehabilitation.

Clinical Relevance:

This case illustrates that elderly patients with apparently benign pelvic fragility fractures might develop severe hemorrhage due to arterial injury, especially when under dual anticoagulation, and stresses the importance of a high index of suspicion. If bleeding is suspected, detailed imaging studies are necessary to determine the source of bleeding and immediate angiographic or surgical interventions in combination with volume resuscitation and coagulation therapy should be readily available.

Fragility fractures of the sacrum: how to identify and when to treat surgically?

The increasing prevalence of fragility fractures of the sacrum (FFS) occurring predominantly in osteoporotic individuals poses a diagnostic and therapeutic challenge. The clinical presentation varies from longstanding low back pain without the patient remembering a traumatic event to immobilized patients after suffering a low-energy trauma. FFS are often combined with a fracture of the anterior pelvic ring; hence they are classified as a part of fragility fractures of the pelvis (FFP). If not displaced, the patients are treated with weight bearing as tolerated and analgesics; however, we advocate to treat displaced fractures surgically according to the fracture personality and the patient’s comorbidities. Surgical options include minimal invasive sacro-iliac screws, trans-sacral bar osteosynthesis, open reduction and internal fixation, or spinopelvic stabilization. In the light of the high complication rate associated with immobilized patients, an operative approach often is indicated to accelerate the patient’s mobility.

Pelvic Insufficiency Fractures

Pelvic insufficiency fractures may occur in the absence of trauma or as a result of low-energy trauma in osteoporotic bone. With a growing geriatric population, the incidence of pelvic insufficiency fracture has increased over the last 3 decades and will continue to do so. These fractures can cause considerable pain, loss of independence, and economic burden to both the patient and the health care system. While many of these injuries are identified and treated based on plain radiographs, some remain difficult to diagnose. The role of advanced imaging in these cases is discussed. In addition to treating the fracture, medical comorbidities contributing to osteoporosis should be identified and corrected. Specific attention has been given to 25-OH serum vitamin D screening and repletion. Treatment generally consists of providing pain control and assisting patients with mobilization while allowing weight bearing as tolerated. In those unable to do so, invasive techniques such as sacroplasty as well as internal fixation may be beneficial. The role of operative fixation in insufficiency fractures is also discussed.

Haemorrhage in fragility fractures of the pelvis

INTRODUCTION

Fragility fractures of the pelvis (FFP) are one of the most visible and debilitating consequences of osteoporosis. In contrast to pelvic ring fractures of the young, fragility fractures are caused by falls from a standing height or even by repetitive physiological loads. Even though haemorrhage is rarely found in fragility fractures of the pelvis, one must be aware of the potential risk.

MATERIALS AND METHODS

In a computer literature search, we identified eight papers about patients with haemorrhage and/or haemodynamic instability as a complication of a low-velocity pelvic ring fracture, all of which were case reports.

CONCLUSION

In our review, an overview of the case reports is provided, risk factors identified and a recommendation for the treatment and clinical observation given.

Delayed bleeding and pelvic haematoma after low-energy osteoporotic pubic rami fracture in a warfarin patient: an unusual cause of abdominal pain

Introduction. Acute abdominal pain may be the presenting symptom in a wide range of diseases in the elderly. Acute abdominal pain related to a delayed bleeding and pelvic haematoma after a low-energy pubic rami fracture is rare and can have important consequences; to the best of our knowledge, only one case has been previously described. Case Report. We present an unusual case of an 83-year-old woman taking warfarin for atrial fibrillation, admitted to the Emergency Department (ED) with acute abdominal pain and progressive anemia related to a delayed bleeding and pelvic haematoma 72 hours after a low-energy osteoporotic pubic rami fracture. Warfarin was withheld, anticoagulation was reversed by using fresh frozen plasma and vitamin K, and concentrated red blood cells were given. Haemoglobin level gradually returned to normal with a progressive resorption of the haematoma. Conclusion. Delayed bleeding and pelvic haematoma after osteoporotic pubic rami fracture should be considered in the differential diagnosis of acute abdominal pain in the elderly. This case indicates the need for hospital admission, careful haemodynamic monitoring, and early identification of bleeding in patients with "benign" osteoporotic pubic rami fracture, especially those receiving anticoagulants, to provide an adequate management and prevent severe complications.

Massive haemorrhage following minimally displaced pubic ramus fractures

BACKGROUND

Fractures of the pubic rami are the most frequent osteoporotic pelvic fracture. Although generally innocuous, epidemiologic research demonstrated a decreased survival in patients with pubic rami fractures compared to healthy controls. Sporadic cases of potentially lethal bleedings have been reported. The aim of this study was to report a consecutive series and review of the literature of patients with severe bleeding following minimally displaced pubic ramus fractures.

MATERIALS AND METHODS

We report on four cases who presented at our emergency department in 2012 and 2013. A systematic review was performed to find other cases of pubic ramus fracture with severe bleeding from the literature.

RESULTS

Four elderly patients presented with severe bleeding following os pubis fracture after trivial falls from ground level. Successful arterial embolisation was performed in two cases. These patients were discharged in good clinical condition. Two other patients were refrained from further treatment due to a pre-existing poor prognosis. Twenty-two additional cases were found in the literature. Successful arterial embolisation was performed in 20 cases, of whom 17 survived.

CONCLUSIONS

Severe bleeding, mostly secondary to corona mortis avulsions, is a rare but potentially lethal complication of pubic ramus fractures. Physicians should be aware of this complication and actively look for symptoms of bleeding. Super-selective arterial embolisation seems safe and highly effective to control bleeding secondary to pubis rami fractures in elderly patients.

Massive haemorrhage from the internal iliac artery following a low energy superior pubic ramus fracture in a 73-year-old man

We report a case of a 73-year-old man with a background of aspirin use who fell and sustained a minimally displaced right superior pubic ramus fracture. He subsequently developed hypotension that necessitated fluid resuscitation, associated with a significant drop in blood haemoglobin levels that required a packed red blood cell transfusion. CT scans revealed the presence of two pelvic haematomas, with ongoing bleeding. An angiogram demonstrated bleeding from the superior vesical branch of the anterior division of the right internal iliac artery, which was successfully embolised with gelfoam slurry. The patient recovered uneventfully thereafter. This is a unique case involving an unexpected injury to the superior vesical branch of the anterior division of the internal iliac artery following low energy trauma to an elderly man. We recommend that patients who develop hypotension following a seemingly-benign isolated pubic ramus fracture be evaluated for concomitant arterial injuries with the relevant CT imaging and angiography.

Delayed presentation of hypovolemic shock after a simple pubic ramus fracture

Although trauma-induced simple pubic ramus fracture is common in the emergency department (ED), it can result in life-threatening hemorrhagic shock. We describe a 58-year-old woman with closed minimally displaced simple pubic ramus fracture. Hemodynamic instability became apparent 2 hours later. She was successfully treated with transarterial embolization and discharged uneventfully 10 days later. Literature review showed involvement of the superior pubic ramus in all reported cases probably because of hemorrhage from “corona mortis” with delay in shock presentation mostly within 6 hours, suggesting at least an equivalent observation period for these patients, particularly those at high risk for hemorrhage.

Corona mortis artery avulsion due to a stable pubic ramus fracture

A 70-year-old woman with osteoporosis fell at home and presented to our emergency department with intense left hip pain. Radiographs revealed a left iliopubic rami fracture and nondisplaced right ischiopubic rami fracture. She was discharged after a 24-hour observation with no clinical changes. Seventy-two hours later, she was readmitted with a painful abdominal mass, progressive oliguria, tachycardia, hypotension, and profuse perspiration with generalized pallor. On physical examination, a painful mass in the hypogastrium and intense inflammation in the thigh and the proximal portion of left knee were found.Emergent multiphase contrast computed tomography revealed a large nonhomogeneous hematoma neighboring the fractured left iliopubic rami, and contrast extravasation indicated arterial bleeding. Selective angiography showed an active hemorrhage from the distal portion of a small branch of the left obturator artery. After embolization of the arterial vessel, the patient was hemodynamically stable. The fracture was rotationally and vertically stable.These fractures are common, especially among the elderly. This type of injury is usually treated conservatively and with active mobilization once the acute pain has subsided. Supraselective embolization after localization of the bleeding vessels by arteriography is recognized as a minimally invasive procedure with excellent outcomes in hemorrhagic complications of pelvic fractures. An apparently benign pubic rami fracture in the setting of hemodynamic instability should raise the suspicion of a corona mortis injury, especially in elderly and anticoagulated patients.

Bladder rupture following osteoporotic pubic ramus and sacral insufficiency fractures

We present a case report of an 86-year-old lady with pubic ramus and sacral insufficiency fractures who developed extra-vesical bladder rupture following displacement of the pubic ramus fracture, a very unusual complication.

Haemodynamic instability secondary to minimally displaced pubic rami fractures: a report of two cases

We report 2 patients with haemodynamic instability secondary to minimally displaced pubic rami fractures following a fall. Both complained of pain and swelling in the abdomen and groin, and had abdominal distension and bruising in the abdomen, groin, and perineum. All these may be early signs of severe vascular injury and should be treated promptly. Both patients were treated with embolisation of the injured vessels using emergency angiography.
