PURPOSE: To summarize and analyze the early treatment of multiple injuries combined with severe pelvic fractures, especially focus on the hemostasis methods for severe pelvic fractures, so as to improve the successful rate of rescue for the fatal hemorrhagic shock caused by pelvic fractures. METHODS: A retrospective analysis was conducted in 68 cases of multiple trauma combined with severe pelvic fractures in recent 10 years (from Jan. 2006 to Dec. 2015). There were 57 males and 11 females. Their age ranged from 19 to 75 years, averaging 42 years. Causes of injury included traffic accidents in 34 cases (2 cases of truck rolling), high falling injuries in 17 cases, crashing injuries in 15 cases, steel cable wound in 1 case, and seat belt traction injury in 1 case. There were 31 cases of head injury, 11 cases of chest injury, 56 cases of abdominal and pelvic injuries, and 37 cases of spinal and limb injuries. Therapeutic methods included early anti-shock measures, surgical hemostasis based on internal iliac artery devasculization for pelvic hemorrhage, and early treatment for combined organ damage and complications included embolization and repair of the liver, spleen and kidney, splenectomy, nephrectomy, intestinal resection, colostomy, bladder ostomy, and urethral repair, etc. Patients in this series received blood transfusion volume of 1200-10,000 mL, with an average volume of 2850 mL. Postoperative follow-up ranged from 6 months to 1.5 years. RESULTS: The average score of ISS in this series was 38.6 points. 49 cases were successfully treated and the total survival rate was 72.1%. Totally 19 patients died (average ISS score 42.4), including 6 cases of hemorrhagic shock, 8 cases of brain injury, 1 case of cardiac injury, 2 cases of pulmonary infection, 1 case of pulmonary embolism, and 1 case of multiple organ failure. Postoperative complications included 1 case of urethral stricture (after secondary repair), 1 case of sexual dysfunction (combined with urethral rupture), 1 case of lower limb amputation (femoral artery thrombosis), and 18 cases of consumptive coagulopathy. CONCLUSION The early treatment of multiple injuries combined with severe pelvic fractures should focus on pelvic hemostasis. Massive bleeding-induced hemorrhagic shock is one of the main causes of poor prognosis. The technique of internal iliac artery devasculization including ligation and embolization can be used as an effective measure to stop or reduce bleeding. Consumptive coagulopathy is difficult to deal with, which should be detected and treated as soon as possible after surgical measures have been performed. The effect of using recombinant factor VII in treating consumptive coagulopathy is satisfactory.

Elevating thin flaps has long been a goal of reconstructive surgeons. Thin flaps have numerous advantages in reconstruction. In this study, we present a surgical method for elevating a thin flap and demonstrate the safety of the procedure. A retrospective review was performed of the electronic medical records of patients who underwent thin flap elevation for lower extremity reconstruction from April 2016 to September 2016 at the Department of Plastic Surgery of Asan Medical Center. All flaps included in this study were elevated above the superficial fascia. A total of 15 superficial circumflex iliac artery free flaps and 13 anterolateral thigh free flaps were enrolled in the study. The total complication rate was 17.56% (n=5), with total loss of the flap in one patient (3.57%) and partial necrosis of the flap in four patients (14.28%). No wound dehiscence or graft loss at the donor wound took place. Elevation above the superficial fascia is not inferior in terms of flap necrosis risk and is superior for reducing donor site morbidity. In addition to its safety, it yields good aesthetic results.

May-Thurner syndrome, also known as iliac vein compression syndrome, is an anatomically variable condition that is characterized by left common iliac vein compression by the right common iliac artery and the lumbar vertebra. This chronic and pulsatile venous compression by the right common iliac artery can cause local intimal injury, inflammation, scarring, and fibrosis, leading to venous outflow obstruction and increased intraluminal pressure. This can cause several complications, such as venous insufficiency, venous claudication, deep vein thrombosis, and very rarely extraperitoneal hematoma due to spontaneous iliac vein rupture. In particular, in middle aged women, hormonal imbalance coupled with these mechanical and inflammatory factors can cause further weakening of the venous wall integrity and develop spontaneous and potentially lethal venous rupture. This paper reports an extremely rare case of a 58-year-old woman with May-Thurner syndrome with acute and extensive deep vein thrombosis of the left lower extremity and a spontaneous extraperitoneal hematoma caused by utero-ovarian vein rupture.

PURPOSE: To evaluate patients who underwent surgical or endovascular treatment after vascular injury related to posterior lumbar disc surgery. MATERIALS AND METHODS: We retrospectively reviewed seven cases of vascular injuries (four lacerations, one arteriovenous fistula [AVF], and two pseudoaneurysms) related to lumbar disc surgery by a posterior approach from January 1997 to December 2016 at Chonnam National University Hospital. Information of patient characteristics, diagnosis, treatment strategies, and outcomes were analyzed. RESULTS: Five out of seven cases were inhospital cases. In three laceration cases, each patient instantly became hypotensive and a life-threatening arterial injury was suspected. Therefore, the patient was immediately turned to the supine position and surgical repair was performed. The patients with pseudoaneurysm and AVF were treated by endovascular intervention. Remaining two were referred cases under the impression of vascular injuries. One laceration case of them was in preshock condition, and the left common iliac artery was surgically repaired. The other referred patient showed pseudoaneurysm which was treated with stent graft insertion. There was no surgery or endovascular intervention related death and none of the patients suffered any sequela related to vascular injury. CONCLUSION: Vascular injury associated with posterior lumbar disc surgery is not common, but can be fatal. Early recognition, diagnosis, and prompt treatment are essential to prevent fatal outcomes. Recently, endovascular intervention is increasingly and preferably used because of its low morbidity and mortality. However surgery is still the best option for the patients with unstable vital sign and endovascular approach can be applied to stable patients.

Vascular complications are uncommon, but it may pose a serious problem in posterior spinal surgery. Vascular injury during lumbar spinal surgery should be suspected if symptoms of circulatory instability are noted. If vascular injury is suspected, a contrast enhanced computed tomography should be checked and proper management, i.e., interventional treatment or surgery should be performed. To date, there have only been a few reports regarding vascular injuries during posterior lumbar spinal surgery. Clinicians should pay attention to signs of vascular injury during posterior spinal surgery, and accordingly, promptly perform treatment. In two patients with retroperitoneal hemorrhage, extravasation of the common iliac arteries was successfully repaired. One patient with pseudoaneurysm was treated by stent placement.

Blunt traumatic injuries to the superior gluteal artery are rare in clinic. A majority of injuries present as aneurysms following penetrating trauma, fracture pelvis or posterior dislocation of the hip joint. We reported a rare case of superior gluteal artery pseudoaneurysm following blunt trauma presenting as large expanding right gluteal hematoma without any bony injury. The gluteal hematoma was suspected clinically, confirmed by ultrasound and the arterial injury was diagnosed by CT angiography that revealed a large right gluteal hematoma with a focal contrast leakage forming a pseudoaneurysm within the hematoma. Pseudoaneurysm arose from the superior gluteal branch of right internal iliac artery, which was successfully angioembolized. The patient was discharged on day 4 of hospitalization with resolving gluteal hematoma. This report highlighted the importance of considering an arterial injury following blunt trauma to the buttocks with subsequent painful swelling. Acknowledgment of this rare injury pattern was necessary to facilitate rapid diagnosis and appropriate treatment.

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 treat- ment 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.

In patients presenting with gunshot wounds, a high clinical suspicion of injury to vasculature and viscera remote from the projectile track is paramount. We present a case of a 17 year old male who sustained a gunshot wound to his abdomen and subsequently developed a right external iliac artery contusion requiring surgery as an indirect effect of the pressure wave from the bullet.

A 36-year-old male presented with progressive exertional dyspnea over months. Physical examination showed jugular venous distension, lung crecipitations, femoral bruit and pitting pedal edema. Echocardiogram showed a dilated right ventricle with severe pulmonary hypertension and a non collapsing inferior vena cava (IVC). On right heart catheterization, IVC oxygen saturation was noted at 92% suggesting arterial mixing; a computed tomography of the abdomen showed a fistula between the right common iliac artery to the right common iliac vein at L4 level and a massive IVC; this was linked to trauma from a disectomy done 16 years ago at L4–L5 level. Endovascular sealing with a 16 × 60 mm bifurcated stent graft (S & G Biotech, Seoul, Korea) was performed which led to complete resolution of the patient’s dyspnea. Iatrogenic vascular injury during lumbar disc surgery, although rare, can lead to high output cardiac failure developing over months to years.
