Critical review of pelvic fractures associated with external iliac artery lesion: a series of six cases

Successfully saving a child with destuctive iliac artery damage by hybrid surgery

Non-iatrogenic trauma of the iliac artery is rarely reported but is always life-threatening. In this report, we describe the case of a child with complete transection and partial disappearance of the iliac artery caused by bicycle handlebar impalement. He experienced catastrophic hemorrhage, malignant arrhythmia, and difficulty in exploring transected vessel stumps. Aggressive infusion, blood transfusion in time, and pediatric vascular characteristics help delay the deterioration during anesthesia induction. Eventually he was successfully rescued by performing interventional balloon occlusion and open revascularization after more than 7 h post-trauma. A series of interventions and precautionary methods may benefit such severely injured patients; thus, these methods should be highlighted.

Isolated blunt iliac artery injury successfully treated with endovascular stent

Common or external iliac artery injury due to blunt trauma is unusual without an associated pelvic fracture. Here we report on a 62 years old man that sustained left external iliac artery thrombosis due to blunt trauma following fall from motorbike. There was no immediate circulatory compromise. Contrasted CT of abdomen revealed an associated left lower abdominal wall traumatic hernia. The iliac artery was intervened with an endovascular stent to restore luminal flow and the hernia was repaired electively. The entire clinical course and management dilemma are described in this article.

An extremely rare disconnection of the external iliac artery and novel collateral remodeling in an endometrial stromal sarcoma woman

Background

Injury to the external iliac artery can have serious consequences and can be extremely challenging for surgeons. Here, we report a patient with bizarre disconnection of the external iliac artery during a laparoscopic operation.

Case presentation

On May 27, 2020, during a laparoscopic pelvic lymphadenectomy operation to treat endometrial stromal sarcoma, we encountered an unusual anatomy: abnormal disconnection of the left external iliac artery in a 26-year-old female patient. The proximal and distal ends of the left external iliac artery demonstrated old narrowing without active bleeding, and the distance between the two disconnected ends was more than 3 cm. The scenario was surprising to all the staff in the operating theater. After a comprehensive assessment of skin temperature, arterial pulsation and arterial blood flow, a multidisciplinary team determined that collateral circulation of the left lower limb had been established and could meet the blood supply of the lower limbs, which was also confirmed three times by computed tomography angiography and Doppler ultrasound of the blood vessels in the abdomen and lower limbs. Sixteen months after the operation, the patient had no obvious abnormality, and the daily activities of the left lower limb were not affected. Follow-up after treatment for the patient is still in progress.

Conclusions

We describe the details of the whole case of disconnection of the external iliac artery. We hope to summarize the experience and lessons learned through this case and a relevant literature review to improve the safety and orderliness of our future clinical work.

Efficacy of median sacral artery embolization for treating severe pelvic fractures: a retrospective study

Objective

Transcatheter arterial embolization (TAE) of bilateral internal iliac arteries (IIAs) in patients with a hemodynamically unstable pelvic fracture is associated with a low mortality rate. The persistence of unstable hemodynamics after IIA embolization indicates the involvement of other arteries, such as the median sacral artery (MSA). This study aimed to evaluate the efficacy of MSA embolization.

Methods

In this single-center, retrospective, observational study, medical records of patients who underwent MSA angiography or embolization for pelvic fractures (n = 21) between January 2007 and August 2019 were reviewed. The percentage of patients achieving hemodynamic stabilization by MSA embolization was calculated.

Results

Fifteen patients underwent MSA embolization, and the remaining six underwent MSA angiography. The shock index value was significantly higher after MSA embolization than that before MSA embolization in hemodynamically unstable patients who underwent this procedure. The success rate of MSA selection was 100%. One patient presented with urinary retention because of bladder and rectal disorders after MSA embolization. The 30-day survival rate was 85.7%.

Conclusions

Severe pelvic fractures, such as a Dennis Zone III fracture and suicidal jumper’s fracture due to trauma from a fall, may require MSA embolization.

Hypotensive Anesthesia does not reduce Transfusion Rates during and after Acetabular Fracture Surgery

BACKGROUND

Acetabular fracture open reduction and internal fixation (ORIF) is generally associated with high intraoperative blood loss. Hypotensive anesthesia has been shown to decrease blood loss and intraoperative transfusion in total joint arthroplasty and posterior spinal fusion. In this study, we assessed the effect of reduction in intraoperative mean arterial pressures (MAPs) during acetabular fracture surgery on intraoperative blood loss and need for transfusion.

METHODS

Three hundred and one patients with acetabular fractures who underwent ORIF at an academic Level 1 trauma center were retrospectively reviewed. Patients were separated based on mean intraoperative MAPs (<60 mmHg, 60-70 mmHg, >70 mmHg). Thirteen patients had mean intraoperative MAP <60 mmHg, 95 had MAP 60-70 mmHg, and 193 had MAP >70 mmHg. Rates of intraoperative and postoperative allogeneic blood transfusion were compared.

RESULTS

Mean intraoperative MAPs were significantly different between groups (p < 0.0001). Time from injury to surgery, estimated blood loss, operative time and intraoperative IV fluids were comparable. The proportion of patients who received blood transfusion and mean units transfused intraoperatively and postoperatively were similar between groups. Mean differences in preoperative and postoperative hemoglobin and hematocrit were also similar. There was no difference in hospital length of stay or perioperative complications between the groups. Multivariate logistic regression analysis demonstrated that body mass index > 30 (p < 0.05) and anterior surgical approach (p < 0.01) were independently associated with intraoperative transfusion and an anterior surgical approach (p < 0.001) was independently associated with postoperative transfusion.

CONCLUSION

Decreased intraoperative MAP during acetabular fracture surgery does not reduce blood loss or need for transfusion. On the other hand, no increased end-organ ischemia was seen with hypotensive anesthesia.

LEVEL OF EVIDENCE

Therapeutic Level III.

Incidence rate and topography of intra-pelvic arterial lesions associated with high-energy blunt pelvic ring injuries: a retrospective cohort study

Background

The aim of this study was to determine the rate and topography of intra-pelvic arterial lesions associated with high-energy blunt pelvic ring injuries (PRI).

Methods

This retrospective cohort study was conducted in a level I trauma center serving 500,000 inhabitants. A total of 127 consecutive patients with high-energy blunt PRI were included between January 1st, 2014 and December 31st, 2017. Every patient had a total body or thoraco-abdominal computed tomography scan including contrast enhanced arterial sequences. A board-certified radiologist reviewed all the vascular images and precisely described every intra-pelvic arterial lesion in terms of localization. Complete pelvic series (standard radiographs and fine cut computed tomography images) were reviewed by three board-certified orthopedic surgeons experienced in PRI management, and Young and Burgess and AO/OTA classifications were determined. Demographic, clinical, therapeutic and outcome data were extracted from the institutional severely injured patients’ registry.

Results

Patients’ mean age was 45.3 years and 58.3% were males. Fifteen (11.8%) had a total of 21 intra-pelvic arterial lesions: seven lesions of the obturator artery, four of the superior gluteal artery, three of the inferior gluteal artery, two of the vesical artery, and one of each of the following arteries: internal iliac, internal pudendal, fifth lumbar, lateral sacral, ilio-lumbar. These lesions occurred in 8.6% of lateral compression injuries, 33.3% of anteroposterior compression injuries and 23.5% of vertical shear and combined mechanism injuries (Young and Burgess classification, p = 0.003); and in 0% of type A injuries, 9.9% of type B injuries and 35% of type C injuries (AO/OTA classification, p = 0.001). Patients with an intra-pelvic arterial lesion were more likely to present with pre-hospital hemodynamic instability (p = 0.046) and to need packed red blood cells transfusion within the first 24 h (p = 0.023; they needed a mean of 7.53 units vs. 1.88, p = 0.0016); however, they did not have a worst outcome in terms of complications or mortality.

Conclusions

This systematic study found an 11.8% rate of intra-pelvic arterial lesion related to high-energy blunt PRI. The obturator, superior gluteal and inferior gluteal arteries were most often injured. These findings are important for the aggressive management of high-energy blunt PRI.

Acute external iliac artery thrombosis following pelvic fractures: Two case reports

RATIONALE

Pelvic fractures associated with acute external iliac artery thrombosis is less common, it is easily ignored in clinical practice, and it can result in limb amputation and hemipelvectomy due to prolonged limb ischemia. We present 2 patients with acute external iliac artery thrombosis following pelvic fractures.

PATIENT CONCERNS

Case 1 is a 49-year-old male with occlusion of the right external iliac artery and pelvic fractures. Case 2 is a 52-year-old male with left external iliac artery occlusion and bilateral internal iliac artery rupture following pelvic fractures.

DIAGNOSES

Case 1 was diagnosed with computed tomography angiography. Case 2 was diagnosed with ultrasound examination and computed tomography angiography.

INTERVENTIONS

Case 1 was performed an open incision to remove thrombus of the right external iliac artery, the right iliac-femoral artery artificial bypass was adopted to restore the blood flow. Case 2 underwent segmental resection of the damaged artery and artificial vascular implantation of left external iliac artery, and angiographic embolization of bilateral internal iliac artery. However, a left hip disarticulation was performed due to osteofascial compartment syndrome at last.

OUTCOMES

Case 1 was cured and discharged smoothly. Case 2 survived but left with a disability after disarticulation.

LESSONS

Acute external iliac artery thrombosis after pelvic fractures is rare and limb-threatening, life-threatening. It is very important to detect and treat this potential complication timely when a patient with a pelvic fracture.

Testicular Dislocation After Unstable Pelvic Ring Injury

Reproductive and genitourinary complications following pelvic ring injuries have been described; however, testicular dislocation is rare and can cause significant morbidity if not managed appropriately. We describe a case of testicular dislocation after pelvic ring injury and outline the subsequent management and outcome, and seek to identify areas of improvement to ensure expedient and appropriate care in the setting of these injuries.

Our case describes a 29-year-old male who presented to a level-one trauma center following a motorcycle collision. An anteroposterior compression type II rotationally unstable pelvic ring was identified on imaging. He was hemodynamically unstable and computed tomography (CT) with angiography was ordered. Arterial extravasation was noted from the bilateral anterior internal iliac arteries, which were subsequently embolized by interventional radiology. However, no concomitant genitourinary injury was identified at the time of CT. After resuscitation, the pelvis was stabilized with an anterior symphyseal plate and bilateral sacroiliac screws. During the anterior pelvic approach, the patient’s dislocated testicle was surprisingly discovered inferior to the pubis. Urology was consulted intra-operatively, and the testicle was successfully relocated. At the final follow-up, the pelvic ring was healed without any noticeable urogenital complication.

While testicular dislocation has been reported in the setting of pelvic ring injury, a paucity of information exists regarding management, implications, and areas for improvement in the identification of these injuries. Therefore, in cases of pelvic ring injury with significant trauma, radiologists, traumatologists, and orthopedic surgeons should adopt a multi-disciplinary approach in diligently attempting to rule out testicular dislocation pre-operatively. Intra-operatively, examination under anesthesia and careful operative technique are important in preventing iatrogenic injury.

Use of anterolateral thigh flap for reconstruction of traumatic bilateral hemipelvectomy after major pelvic trauma: a case report

Background

Major pelvic trauma (MPT) with traumatic hemipelvectomy (THP) is rare, but it is a catastrophic health problem caused by high-energy injury leading to separation of the lower extremity from the axial skeleton, which is associated with a high incidence of intra-abdominal and multi-systemic injuries. THP is generally performed as a lifesaving protocol to return the patient to an active life.

Case report

A 12-year male patient exposed to major pelvic trauma with bilateral THP survived the trauma and multiple lifesaving operations. The anterolateral thigh flap is the method used for wound reconstruction. The follow-up was ended with colostomy and cystostomy with wheelchair mobilization. To the best of our knowledge, there have been a few bilateral THP reports, and our case is the second one to be successfully treated with an anterolateral thigh flap.

Conclusion

MPT with THP is the primary cause of death among trauma patients. Life-threatening hemorrhage is the usual cause of death, which is a strong indication for THP to save life.

[Mechanism and surgical treatment of acetabular roof column fractures with external iliac arterial injury: analysis of 4 cases]

Pelvic arterial injuries caused by pelvic or acetabular fractures are rare (15%-20%), and the complication by external iliac artery (EIA) injuries is even rarer, which can result in a mortality rate as high as 75%-83%. The mechanism of major artery damage caused by pelvic or acetabular fractures remains unclear. We report our experience with surgical treatment of 4 patients with acetabular roof column fracture and EIA injury. All the 4 patients underwent injury control resuscitation and surgery after admission. One patient died of multiple organ dysfunction syndrome (MODS), and the other 3 patients recovered smoothly. In these cases, as we presume, the occurrence of acetabular roof column fracture caused the EIA, which was connected to the iliopsoas muscle through soft tissues such as the iliac fascia, to be pulled into the fracture space along with the iliopsoas muscle and was cut directly by the fracture end; the EIA may also be punctured during transport and fracture reduction. Although acetabular roof column fractures with EIA injuries rarely occur, the consequences can be fatal. In such cases, clinicians should be highly vigilant about the possibility of large vessel injuries, and its early detection using threedimensional vascular reconstruction based on CT vessels or arterial interventional angiography can be critical for implementation of early treatment to save the limbs.

Sacral fractures: issues, challenges, solutions

Sacral fractures are a heterogeneous group of fractures occurring in young people following road traffic accidents and falls from height, or in the elderly with osteoporosis following trivial trauma.This heterogeneity, combined with the low incidence of sacral fractures, determines a lack of experience amongst physicians, often leading to misdiagnosis, underestimation and inadequate treatment. The diagnosis should be made by assessing specific features during the clinical presentation, while computed tomography (CT) scan continues to be the choice of investigation.Sacral fractures can be treated non-operatively or surgically. Non-operative treatment is based on rest, pain relief therapy and early mobilization as tolerated. Surgical techniques can be split into two main groups: posterior pelvic fixation techniques and lumbopelvic fixation techniques. Anterior pelvic fixation techniques should be considered when sacral fractures are associated with anterior pelvic ring injuries, in order to increase stability and reduce the risk of posterior implant failure. To improve fracture reduction, different solutions could be adopted, including special positioning of the patient, manipulation techniques and use of specific reduction tools. Patients suffering from spinopelvic dissociation with associated neurologic lesions hardly ever recover completely, with residual lower-limb neurologic sequelae, urinary problems and sexual disfunction.Herein, we present issues, challenges and solutions related to the management of sacral fractures.

Use of the autologous spiral vein graft: a two-stage iliac bypass in a potentially fatal case of pelvic trauma and contaminated tissues

Serious problems may be encountered in arterial or venous reconstruction in cases of severe trauma and contaminated tissues. We report the use of a spiral venous graft (SVG) in a case of two-stage bypass aimed at saving first life, and then the extremity.

Severe open and contaminated injury was present in the lower abdomen and pelvic region of 29-year-old woman brought to the emergency department following a traffic accident. The patient was in shock, and was taken for emergency surgery jointly with the relevant departments. Interposition bypasses with synthetic graft were performed in the first stage. The synthetic grafts were subsequently removed due to problems developing secondary to infection at subsequent follow-up, and revascularization was established with autologous grafts together with SVG.

SVGs are alternative grafts in cases with contaminated tissues and requiring major vessel reconstruction. This technique can add to the therapeutic options available.

Prospective validation of a new protocol with preperitoneal pelvic packing as the mainstay for the treatment of hemodynamically unstable pelvic trauma: a 5-year experience

PURPOSES

Hemodynamically unstable pelvic trauma has been a significant challenge even in most experienced Trauma Centres. In 2011 preperitoneal pelvic packing (PPP) was introduced in our Hospital as the first manoeuvre. This study aims to review overall mortality at 24 h from arrival in the emergency department.

METHODS

A retrospective review of our prospective database was performed considering patients with systolic blood pressure (SBP) < 90 mmHg or with the need for more than 2 Units of packed red blood cells (PRBC) on admission in the emergency department, (ED) and a pelvic fracture. Values were expressed as a median and interquartile range. Continuous variables were compared with the Mann-Whitney test.

RESULTS

Between September 2011 and December 2016, we treated 30 patients. Median age was 51 years (40-65) and Injury Severity Score 36 (34-42). SBP in the ED was 90 (67-99), heart rate was 115 (90-130), Base Excess - 8 (- 11.5/- 4.8), pH 7.23 (7.20-7.28). Median PRBC requirements during the first 24 h (from admission) were 13 Units (8-18.8). Time to emergency treatment was 63 min (51-113). 17 patients (56.6%) underwent angiography after PPP. Overall 24 h mortality was 30%. A comparison between survivors and non-survivors showed no statistically significant differences between groups.

CONCLUSIONS

In our experience, PPP resulted to be quick to perform and effective. No death occurred from direct pelvic bleeding.

Where and what arteries are most likely injured with pelvic fractures?: The Influence of Localization, Shape, and Fracture Dislocation on the Arterial Injury During Pelvic Fractures

Blood vessels passing through pelvic region come into intimate contact with pelvic bone and can be injured by the sharp edges of the dislocated fracture fragments. The aim of the study was to evaluate the influence of localization, shape, and dislocation of individual pelvic ring bones' fractures on arterial injuries. The study group consisted of 474 patients enrolled in a 1-year prospective multicenter study. The pattern of pelvic fracture lines was characterized and recorded on a planar diagram of the subjected side of the pelvis. The diagram was subdivided into 11 designated areas. Frequency of injury at each 11 areas was recorded. The course of individual arteries in the 11 areas was also recorded in relation to each type of pelvic fractures. Out of the 474 investigated patients, the highest proportion of fractures occurred in the areas of the superior (62%) and inferior (59%) ramus of the pubis as well as in the lateral part of the sacrum (19%). These locations can be associated with injuries of the external iliac, obturator, internal iliac, and aberrant obturator arteries. The highest risk of arterial injuries was associated with vertically displaced fractures in the middle part of the superior and inferior pubic rami, along the ischial ramus, in the apex of the greater sciatic notch and in the vicinity of the ventral part of the sacroiliac joint, where the artery runs at a distance of less than 1 cm from the bone.

Traumatic Hemipelvectomy with a Contralateral Unstable Pelvis and Acetabular Fracture: A Case Report and Review of the Literature

CASE

A traumatic hemipelvectomy (THP) is a rare life-threatening injury, with limited reports in the civilian population. We present the case of a patient who sustained a massive pelvic injury with an incomplete unilateral THP, a contralateral unstable pelvis, and a fracture of the acetabulum.

CONCLUSION

With advancements in resuscitative techniques, carefully timed and planned surgical interventions, and a coordinated multidisciplinary approach, a greater number of patients may be able to survive a massive pelvic injury.

Intra-pelvic pressure changes after pelvic fracture: A cadaveric study quantifying the effect of a pelvic binder and limb bandaging over a bolster

INTRODUCTION

Unstable pelvic fractures can be life-threatening due to catastrophic haemorrhage. Non-invasive methods of reducing and stabilising these injuries include pelvic binder application and also lower limb bandaging over a knee-flexion bolster. Both of these methods help close the pelvic ring and should tamponade bleeding. This study aimed to quantify the intra-pelvic pressure changes that occurred with 3 different manoeuvres: lower limb bandaging over a bolster; a Trauma Pelvic Orthotic Device (T-POD) pelvic binder, and a combination of both.

METHODS

Following a pilot study with 2 soft embalmed cadavers, a formal study with 6 unembalmed cadavers was performed. For each specimen an unstable pelvic injury was created (OA/OTA 61-C1) by dividing the pelvic ring anteriorly and posteriorly. A 3-4cm manometric water-filled balloon was placed in the retropubic space and connected to a 50ml syringe and water manometer via a 3-way tap. A baseline pressure of 8cmH₂O (equating to the average central venous pressure) was used for each cadaver. Steady intra-pelvic pressures (more reliably reflecting the pressures achieved following an intervention) were used in the subsequent statistical analysis, using R statistical language and Rstudio. Paired t-test or Wilcoxon's rank sum test were used (depending on the normality of the dataset) to determine the impact of each intervention on the intra-pelvic pressure.

RESULTS

The mean steady intra-pelvic pressures were significantly greater than the baseline pressure for each intervention. The binder and limb bandaging over a bolster alone increased the mean steady pelvic pressures significantly to 24 (SE=5) (p<0.036) and 15.5 (SE=2) (p<0.02)cmH₂O respectively. Combining these interventions further increased the mean steady pressure to 31 (SE=7)cmH₂O. However, this was not significantly greater than pressures for each of the individual interventions.

DISCUSSION

Both lower limb bandaging over a bolster and pelvic binder application significantly increased intra-pelvic pressure above the baseline pressure. This was further increased through combining these interventions, which could be useful clinically to augment haemorrhage control in these fractures.

CONCLUSION

Lower-limb bandaging over a bolster, and pelvic binder application, both significantly increased intra-pelvic pressures, and were greatest in combination. These findings support the use of these techniques to facilitate non-surgical haemorrhage control.

Traumatic pelvic fractures in children and adolescents

Although traumatic pelvic fractures in children are relatively rare, these injuries are identified in about 5% of children admitted to level 1 trauma centers after blunt trauma.^1-4 Such injuries differ from adult pelvic fractures in important ways and require distinct strategies for management. While the associated mortality rate for children with pelvic fractures is much lower than that for adults, the patient may require urgent surgical intervention for associated life-threatening injuries such as head trauma and abdominal injury. Unstable pelvic ring fractures should be acutely managed using an initial approach similar to that used in adult orthopedic traumatology. Although very few pediatric pelvic fractures will ultimately need surgical treatment, patients with these injuries must be followed over time to confirm proper healing, ensure normal pelvic growth, and address any potential complications. The trauma team suspecting a pelvic fracture in a child must understand the implication of such a finding, identify fracture patterns that increase suspicion of associated injuries, and involve pediatric or adult orthopedic specialists as appropriate during the management of the patient.

Fracture of the acetabulum with femoral artery injury presenting late: A case report

This study reports a rare case of both column acetabulum fracture with femoral artery injury that presented late and was managed with arterial reconstruction and fracture fixation.

A thirty-one year old man sustained both column acetabular fracture on the left in a motor vehicle accident. On admission there was no obvious neuro-vascular deficit. During surgery for the fracture after 7 days of the injury the femoral artery was found to be severely crushed with no blood flow. The anterior column of the acetabulum was stabilised followed by resection and reconstruction of the femoral artery. The post-operative period was uneventful and he was discharged normally. At 6 months from injury the fractures had united well with excellent limb circulation and good lower limb function.

Femoral artery injury with acetabular fracture is rare and late presentations are unreported hitherto. The results of fracture stabilisation and vessel reconstruction seem to be excellent. Literature of similar injuries is reviewed.

Combat-Related Hemipelvectomy: 14 Cases, a Review of the Literature and Lessons Learned

OBJECTIVES

Trauma-related hemipelvectomy is a rare and often fatal injury that poses a number of challenges to the treating surgeon. Our objective was to identify patient and injury characteristics that have proven difficult to treat, and to describe management techniques.

DESIGN

Retrospective review.

SETTING

Level II trauma center.

PATIENTS

Thirteen consecutive patients who underwent 14 combat-related hemipelvectomies between 2001 and 2013.

INTERVENTION

We reviewed our prospective trauma registry, along with the patients' medical records, radiographs, and clinical photographs.

MAIN OUTCOME MEASUREMENTS

Injury severity scores, required surgical procedures, ambulatory status, and bowel and bladder function.

RESULTS

Hemipelvectomy was indicated for insufficient soft tissue coverage, complicated by life-threatening local infection and/or a dysvascular hemipelvis. Five patients underwent resection for angioinvasive fungal infections. All patients sustained a genitourinary injury, with 7 requiring suprapubic catheters and all undergoing diverting colostomy. After a median of 2 years of follow-up, 2 patients had normal urinary continence and 3 regained fecal continence. The surviving patients required a mean of 44 operations. One patient returned to community ambulation.

CONCLUSIONS

This is the largest published series of trauma-related hemipelvectomies. Our lessons learned may benefit civilian surgeons who are confronted with high-energy open injuries to the pelvic girdle. Although the decision to perform hemipelvectomy should not be taken lightly, this procedure can be lifesaving and should be performed in a timely fashion when indicated.

LEVEL OF EVIDENCE

Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Femorofemoral bypass allowed limb preservation after late diagnosis of left common iliac artery thrombosis due to blunt trauma: A case report

Objective:

Acute common iliac artery occlusion which results from blunt abdominal trauma is rare and potentially leads to a late diagnosis.

Methods:

We report a case of a 58-year-old patient who suffered a late diagnosed acute left common iliac artery occlusion secondary to abdominal trauma. An emergency exploratory laparotomy was performed to stop intra-abdominal bleeding, while his left limb ischemia was not noticed until 32 h later and femorofemoral bypass was then successfully performed for revascularization. Compartment syndrome was observed postoperatively, and fasciotomy was performed promptly. The wound was temporarily covered with Vaccum Sealing Drainage due to high skin tension. Patient underwent skin-grafting after leg swelling subsided.

Results:

The follow-up turned out that these managements were valid in the preservation of the limb viability.

Conclusions:

This case highlights the prudent recognition of the acute lower extremity ischemia in the abdominal trauma and immediate remedy for acute iliac artery occlusion after a late diagnosis.
