Pedicled abdominal flap using deep inferior epigastric artery perforators for forearm reconstruction: A case report

BACKGROUND Pedicled abdominal flaps are a widely used surgical technique for forearm reconstruction in patients with soft tissue defects.However,some drawbacks include restricted flap size,partial flap loss,and donor-site morbidity.To address these concerns,we present a case of a pedicled abdominal flap using the deep inferior epigastric artery perforators(DIEP)for forearm reconstruction in a patient with a large soft tissue defect.CASE SUMMARY A 46-year-old male patient was admitted to our hospital with forearm injury caused by a pressing machine.A 15 cm×10 cm soft tissue defect with complete rupture of the ulnar side structures of the forearm was found.One week after orthopedic management of the neurovascular injury and fractures using the first stage of Masquelet technique,the patient was referred to the plastic and recon-structive surgery department for wound coverage.Surgical debridement and negative-pressure wound therapy revealed a 20 cm×15 cm soft tissue defect.A pedicle abdominal flap with the DIEP was used to cover the defect.Three weeks later,the flap was detached from the abdomen,and the abdominal defect was directly closed.Subsequently,the second stage of Masquelet technique was performed at the fracture site at week 10.Finally,all donor and recipient sites healed without complications,such as flap dehiscence,infection,hematoma,or necrosis.Fracture site osteosynthesis was achieved without complications.CONCLUSION Pedicled abdominal flap using the DIEP provides a reliable option for forearm reconstruction in patients with large soft tissue defects.

Missed diagnosis of femoral deep artery rupture after femoral shaft fracture: A case report

BACKGROUND Vascular injury is a rare complication of femoral shaft fractures,and rupture of the deep femoral artery is more difficult to diagnose because of its anatomical location and symptoms.Despite its low incidence,deep femoral artery rupture can lead to life-threatening outcomes,such as compartment syndrome,making early identification and diagnosis critical.CASE SUMMARY A 45-year-old male patient was admitted to our hospital due to right lower limb trauma in a car accident,with complaints of severe pain and swelling on his right thigh.X-ray demonstrated a right femoral shaft fracture.During preparation for emergency surgery,his blood pressure and blood oxygen saturation dropped,and sensorimotor function was lost.Computed tomography angiography was performed immediately to confirm the diagnosis of rupture of the deep femoral artery and compartment syndrome,so fasciotomy and vacuum-assisted closure were performed.Rhabdomyolysis took place after the operation and the patient was treated with appropriate electrolyte correction and diuretic therapy.Twenty days after the fasciotomy,treatment with the Hoffman Type II External Fixation System was planned,but it was unable to be immobilized internally based on a new esophageal cancer diagnosis.We kept the external fixation for 1 year,and 3 years of follow-up showed improvement of the patient’s overall conditions and muscle strength.CONCLUSION For patients with thigh swelling,pain,anemia,and unstable vital signs,anterior femoral artery injury should be highly suspected.Once diagnosed,surgical treatment should be performed immediately and complications of artery rupture must be suspected and addressed in time.

Fatal complication, rescue therapy;covered stent for coronary artery perforation

Introduction: Although coronary perforation is a rare complication observed during intervenetional procedures, it has a considerably high mortality rate. The prevelance of coronary perforation has been reported to be 0.20%-0.6%. Its sudden development, the patient’s agitation and development of rapid collapse render intervention difficult. Materials and Method: The presence of perfusion balloon and covered stent in clinics is life-saving. In the present study, we retrospectively reviewed 17 cases with coronary artery perforation that were treated between 2009 and 2012. Of these patients, 10 (58.8%) were men and 7 (41.2%) were women;the median age was 62.8 ± 8.3 years. The coronary artery perforation resulted from guide wire in 23.5%, balloon dilatation in 58.8% and stent implantation in 17.6%. All the lesions were either type B or C lesions. Results: The extensiveness of perforation was Ellis grade I in 23.5%, grade II in 47.1% and grade III in 29.4% of the cases. In the treatment of the perforation, polytetrafluoroethylene-covered stent graft was implemented in 9 (52.9%) patients, whilst conventional and emergency surgical therapy was performed in 8 (47.1%) patients. Grade I perforations occurred due to the guide wire and were managed with conventional therapy (p < 0.05). Grade II and III perforations resulted from balloon and stent. The majority of these patients were inserted Graft Stent (stent graft in 52.9% and conventional therapy in 23.5% of the cases (p < 0.05). Although all the stent grafts were successfully implanted, the complete control of bleeding was achieved only in 77.7% of the patients. Mortality was not observed in grade I perforation, whilst all cases resulted in mortality had grade III perforation. Conclusion: These data indicate that there is a need for further advanced technology in the coronary artery perforation despite of currently available therapeutic options.

Devastating complication of negative pressure wound therapy after deep inferior epigastric perforator free flap surgery:A case report

BACKGROUND Thermal injuries on free transferred or replanted tissues resulting from loss of sensibility are an infrequent occurrence.They require immediate and appropriate management before they progress to an irreversible condition.Although negative pressure wound therapy(NPWT)can prevent wound progression by increasing microcirculation,the inappropriate application of NPWT on complicationthreatened transferred and replanted tissues can induce an adverse effect.CASE SUMMARY A 48-year-old woman who underwent immediate breast reconstruction with a deep inferior epigastric artery perforator free flap.While applying a heating pad directly to the flap site,she sustained a deep second to third-degree contact burn over 30%of the transferred flap on postoperative 7 d.As the necrotic changes had progressed,we applied an NPWT dressing over the burned area after en-bloc debridement of the transferred tissues on postoperative 21 d.After 4 d of NPWT application,the exposed fatty tissues of the flap changed to dry and browncolored necrotic tissues.Upon further debridement,we noted that the wound gradually reached total necrosis with a collapsed vascular pedicle of deep inferior epigastric artery.CONCLUSION Although NPWT has been shown to be successful for treating various wound types,the significant risk of NPWT application in short-lasting reconstructed flap wounds after thermal injury should be reminded.

Gelfoam embolization for distal, medium vessel injury during mechanical thrombectomy in acute stroke: A case report

BACKGROUND Arterial perforation has inevitably increased as endovascular treatments have become more common for intracranial large vessel occlusions,and even distal,medium vessel occlusions.A distal,medium vessel has a tortuous course and thinner wall compared to large arteries,making it more susceptible to damage.Here,we review the treatment strategies for arterial perforation during mechanical thrombectomy,and we report the case of a patient treated with gelfoam embolization.CASE SUMMARY A 63-year-old woman presented to the emergency department with sudden neurologic symptoms of right hemiparesis and global aphasia.The initial National Institutes of Health Stroke Scale score was 15.Computed tomography(CT)and CT angiography revealed hyperacute infarction and emergent arterial occlusion of the left middle cerebral artery M2-3 portion.During endovascular mechanical thrombectomy,arterial rupture occurred.The patient’s vital signs were stable,but delayed angiography showed persistent active bleeding.Therefore,selective embolization of the injured artery was performed using gelfoam.Subsequent left vertebral and internal carotid angiography was performed to confirm hemostasis.A localized subarachnoid hemorrhage(SAH)was confirmed on a follow-up CT scan.A repeated CT scan after 12 d showed resolution of the SAH,and rebleeding did not occur.CONCLUSION Rescue embolization with gelfoam could be considered an additional option in distal,medium vessel perforation.

Quadrilobed superior gluteal artery perforator flap for sacrococcygeal defects

Background Perforator flaps are used extensively in repairing soft tissue defects. Superior gluteal artery perforator flaps are used for repairing sacral defects, but the tension required for direct closure of the donor area after harvesting of relatively large flaps carries a risk of postoperative dehiscence. This research was to investigate a modified superior gluteal artery perforator flap for repairing sacrococcygeal soft tissue defects. Methods From June 2003 to April 2010, we used our newly designed superior gluteal artery perforator flap for repair of sacrococcygeal soft tissue defects in 10 patients （study group）. The wound and donor areas were measured, and the flaps were designed accordingly. Wound healing was assessed over a follow-up period of 6-38 months. From January 1998 to February 2003, twelve patients with sacrococcygeal pressure sores were treated with traditional methods, VY advancement flaps or oblong flaps, as control group. Results After debridement, the soft tissue defects ranged from 12 cm× 10 cm to 26 cm× 22 cm （mean 16.3 cm× 13.5 cm）. Four patients were treated using right-sided flaps ranging from 15 cm × 11 cm to 25 cm × 20 cm （mean 18.2 cm × 14 cm）. Four patients were treated using left-sided flaps, and two were treated using both right- and left-sided flaps. Suction drains were removed on postoperative Days 3-21 （mean 5.9） and sutures were removed on postoperative Days 12-14. Each flap included 1-2 perforators for each of the donor and recipient sites. Donor sites were closed directly. All flaps survived. In eight patients, the wounds healed after single-stage surgery. After further debridement, the wounds of the remaining two patients were considered healed on postoperative Days 26 and 33, respectively. The rate of first intention in the study group （80%, 8/10） significantly increased than that of control group （（25%, 3/12）, X2=4.583, P=0.032）. Follow-up examinations found that the flaps had a soft texture without ulceration. In the two patients without paraplegia, the range of motion of the hip joints was not affected. Conclusion The use of the quadrilobed superior gluteal artery perforator flap can overcome the disadvantages of traditional perforator flaps and represents an improved approach for repairing soft tissue defects in the sacrococcygeal region.

Management of coronary artery perforation by embolization:nursing experience from 3 cases

INTRODUCTION With the development of economy and improvement of life quality,the incidences of hypertension,hyper-cholesterolemia,diabetes,obesity and smoking have been increased in China,which has led to a significant increase in the morbidity and mortality of coronary artery disease（CAD）~1.Since it was introduced into China in 1984,coronary intervention（PCI）has developed rapidly and has become the major treatment of CAD because of its unique characteristics of minimal invasive and effective outcome.

Clinical outcomes of percutaneous coronary intervention for chronic total occlusion lesions in remote hospitals without on-site surgical support

Background The safety of percutaneous coronary intervention （PCI） for chronic total occlusion （CTO） lesions in remote hospitals without surgical facilities remains unknown. This study aimed to evaluate three-year outcomes after CTO for PCI in ten centers around China where no on-site coronary artery bypass grafting （CABG） support was available. Methods A total of 152 patients from 10 Chinese hospitals without on-site surgical facilities were prospectively studied. Intra-procedural and in-hospital events were assessed. Angiographic follow-up was indexed eight months after the initial procedure. Clinical follow-up was extended to three years. The primary outcome was the rate of major adverse cardiac events （MACE）, defined as cardiac death, myocardial infarction and target-vessel revascularization （TVR）. Results The incidence of CTO was 7.9% in patients who underwent PCI, Successful recanalization was achieved in 132 patients （86.8%）. Compared with patients in the PCI success group, patients with PCI procedural failure had longer lesion lengths （（42.32±22.08） mm vs （27.61±22.85） mm, P=0.023）, a higher rate of perforation （25.0% vs 0, P=0.014）, and a greater need for pericardial puncture. There were significant differences in MACE in-hospital and at one year and three years between the failure （10.0%, 30.0% and 35.0%） and the success （3.0%, 12.1% and 14.4%） groups （P=0.037, 0.034 and 0.040, respectively）. These led to a significant decrease in the MACE-free survival rate at one and three years in the failure group, compared with the success group （P=0.031 and 0.023, respectively）. Stump was the only predictor of recanalization success （HR 0.158, 95% Cl 0.041-0.612, P=0.008）, whereas procedural failure （OR 13.023, 95% CI 6.67-13.69, P=0.002）, incomplete revascularization （OR 9.71, 95% CI 2.93-5.59, P=0.005）, and total stent length （OR 6.02, 95% Cl 1.55-11.93, P=0.027） were three independent predictors of MACE. Conclusions PCI for CTO was unsafe in remote hospitals without CABG facilities. Paying attention to coronary perforation is important for successful procedures.
