Assessment of Total Incapacity for Work or Incapacity in the Criminal Sense in Case of Penetrating Wounds of the Neck

Penetrating wounds of the neck are often life-threatening. The victims are exposed to vascular and laryngotracheal lesions. The purpose of this work is to report the various aspects of the management of penetrating wounds in our context and to make the medico-legal assessment of incapacity in the criminal sense or total incapacity for work. This is a retrospective study (2002-2014) on thirty-nine (39) cases of penetrating neck wounds, received at the ENT departments of the Aristide Le Dantec and Fann University Hospital Centers. Patients were predominantly male, representing 94% of cases with an average age of 27 years. Seventy (70%) of the accidents occurred in the region of Dakar. In 42% of cases, the circumstance of occurrence was a fight or an assault. The weapon used in most cases by the aggressor was a cutter or a knife. The average waiting time was 37 hours with extremes of 02 and 216 hours. Surgically, all patients had been examined under general anesthesia. In terms of lesions, 37 cases had profound cervical muscle injuries, i.e. 94%. There were 17 vascular lesions (43%). The medico-legal distribution of patients showed that among them, 10% had a total incapacity to work exceeding 21 days. The determination of total incapacity for work is an important medical procedure that requires capability and experience. The doctor must not fall into the trap of the confusion between the TIW on the criminal level and the TIW on the civil level. He must limit medically and should not make judgments.

Management and Prognostic Factors of Penetrating Craniocerebral Wounds at One Teaching Hospital in Benin

Introduction. Penetrating craniocerebral wounds (PCCWs) are a particular lesion in the category of traumatic brain injury (TBI). The objective of this study was to describe the management of these lesions, and to identify signifiant risk factors associated with mortality in patients with a PCCW. Methods. It was a transversal, descriptive and analytical study performed in Departmental Teaching Hospital of Borgou and Alibori in Benin. From January 1, 2015 to June 30, 2020, patients with a PCCW were retained. Risk factors of mortality and morbidity associated to etiological, clinical and surgical parameters were assessed using the chi-square test. p value < 0.05 was considered to be statistically significant. Results. During the study period, 1267 cases of traumatic brain injuries (TBI) were admitted. Of these patients, 77 (6.1%) cases of PCCW were retained. These patients were divided into 66 (85.7%) male and 11 (14.3%) female. The mean age of the patients was 22.6 ± 14.8 years (range from 2 years to 70 years). The circumstances of occurrence were a traffic accident in 42 (54.5%) cases, an assault in 33 cases (42.9%) and a fall 2 (2.6%). The PCCW was unilateral in 71 cases (92.2%). A brain CT-scan was performed in 60 (77.9%) patients. Surgery was performed in 69 (89.6%) patients. Post-operative outcomes were simple in 59 (85.5%) cases. GCS, pupillary abnormalities, motor deficit were a statistically significant risk factor associated with death or sequels (p < 0.0001). Conclusion. The identification of risk factors of mortality or sequels is a major step for an efficient management of PCCWs and a reduction of morbidity and mortality. Whatever strategies are adopted, prevention must remain a priority.

The Application of Bilayer Artificial Dermis Combined with VSD Technology in Chronic Wounds

Background: Bilayer artificial dermis promotes wound healing and offers a treatment option for chronic wounds. Aim: Examine the clinical efficacy of bilayer artificial dermis combined with Vacuum Sealing Drainage (VSD) technology in the treatment of chronic wounds. Method: From June 2021 to December 2023, our hospital treated 24 patients with chronic skin tissue wounds on their limbs using a novel tissue engineering product, the bilayer artificial dermis, in combination with VSD technology to repair the wounds. The bilayer artificial dermis protects subcutaneous tissue, blood vessels, nerves, muscles, and tendons, and also promotes the growth of granulation tissue and blood vessels to aid in wound healing when used in conjunction with VSD technology for wound dressing changes in chronic wounds. Results: In this study, 24 cases of chronic wounds with exposed bone or tendon larger than 1.0 cm2 were treated with a bilayer artificial skin combined with VSD dressing after wound debridement. The wounds were not suitable for immediate skin grafting. At 2 - 3 weeks post-treatment, good granulation tissue growth was observed. Subsequent procedures included thick skin grafting or wound dressing changes until complete wound healing. Patients were followed up on average for 3 months (range: 1 - 12 months) post-surgery. Comparative analysis of the appearance, function, skin color, elasticity, and sensation of the healed chronic wounds revealed superior outcomes compared to traditional skin fl repairs, resulting in significantly higher satisfaction levels among patients and their families. Conclusion: The application of bilayer artificial dermis combined with VSD technology for the repair of chronic wounds proves to be a viable method, yielding satisfactory therapeutic effects compared to traditional skin flap procedures.

Double-nylon purse-string suture in closing postoperative wounds following endoscopic resection of large(≥3 cm)gastric submucosal tumors

BACKGROUND Endoscopic full-thickness resection(EFTR)of gastric submucosal tumors(SMTs)is safe and effective;however,postoperative wound management is equally important.Literature on suturing following EFTR for large(≥3 cm)SMTs is scarce and limited.AIM To evaluate the efficacy and clinical value of double-nylon purse-string suture in closing postoperative wounds following EFTR of large(≥3 cm)SMTs.METHODS We retrospectively analyzed the data of 85 patients with gastric SMTs in the fundus of the stomach or in the lesser curvature of the gastric body whose wounds were treated with double-nylon purse-string sutures after successful tumor resection at the Endoscopy Center of Renmin Hospital of Wuhan University.The operative,postoperative,and follow-up conditions of the patients were evaluated.RESULTS All tumors were completely resected using EFTR.36(42.35%)patients had tumors located in the fundus of the stomach,and 49(57.65%)had tumors located in the body of the stomach.All patients underwent suturing with double-nylon sutures after EFTR without laparoscopic assistance or further surgical treatment.Postoperative fever and stomach pain were reported in 13(15.29%)and 14(16.47%)patients,respectively.No serious adverse events occurred during the intraoperative or postoperative periods.A postoperative review of all patients revealed no residual or recurrent lesions.CONCLUSION Double-nylon purse-string sutures can be used to successfully close wounds that cannot be completely closed with a single nylon suture,especially for large(≥3 cm)EFTR wounds in SMTs.

Eyelid Wounds: Epidemiological, Clinical and Etiological Aspects

Purpose: The aim is to show epidemiological, clinical and etiological characteristics of palpebral wounds. Methodology: This was a retrospective study focusing on patients with an eyelid wound, over a 10-year period from 2012 to 2021. We collected and analyzed the data using Excel. Results: The frequency of eyelid wounds was 0.1%. The average age of our patients was 19.38 years with a range of 1 and 62 years. The sex ratio was 3.7. Eighty-one percent of patients lived in Dakar. Fifty-seven percent (57%) of patients consulted less than 24 hours after the trauma and 7% of patients on D1. The circumstances were brawls (11%), domestic accidents (9%), road accidents (6%), and work accidents (6%). We noted 1 case of dog bite. Thirteen patients presented with post-traumatic decreased visual acuity. Involvement of the isolated upper eyelid was noted in 40% of cases and both eyelids in 15% of cases. Involvement of the lacrimal ducts was noted in 17% of cases, and that of the free edge in 21% of cases. Eyelid wounds were associated with eyeball damage in 21% of cases. Various associated lesions were observed. Ninety-one percent of patients received surgical treatment. Three cases of superinfections, 1 case of conjunctival granuloma and 1 case of phthysis of the eyeball with postoperative retinal detachment were noted. Conclusion: Eyelid sores are relatively common in our context. They require rapid surgical treatment in order to preserve the functional and aesthetic prognosis. .

A surgical alternative of fusiform penetrating keratoplasty for the management of severe infectious keratitis

AIM:To describe the surgical procedure of fusiform penetrating keratoplasty(FPK)using multiple trephines of different sizes for treating patients with severe infectious keratitis.METHODS:Fourteen eyes underwent FPK,and 15 eyes received conventional penetrating keratoplasty(PK)were included in the study.The best-corrected visual acuity(BCVA),refractive outcomes,endothelial cell density,and postoperative complications were recorded.RESULTS:The FPK group was followed for an average of 15.3±2.1mo,whereas the PK group was followed for 16.1±1.9mo.The corneal ulcers were elliptical-shaped in all 14 eyes in the FPK group.The mean BCVA(logMAR,0.26±0.13)showed no statistically significant differences from that in the PK group(logMAR,0.21±0.12,P>0.05)at 1y after surgery.But the mean curvature,mean astigmatism,and mean spherical equivalent in the FPK group were lower than those in the PK group(P<0.05).Peripheral anterior synechia was observed in one patient in the FPK group,whereas 6 patients in the PK group.Suture loosening and neovascularization were observed in 4 and 5 eyes in the PK group,respectively.No graft immune rejection or elevation of intraocular pressure was observed in the two groups.CONCLUSION:For patients with elliptical-shaped corneas or corneal ulcers,FPK can avoid disrupting of corneal limbus,reduce the risk of postoperative complications,and can result in satisfactory visual quality.

3D-bioprinted tri-layered cellulose/collagen-based drug-eluting fillers for the treatment of deep tunneling wounds

Tunneling wounds create passageways underneath the skin surface with varying sizes and shapes and can have twists and turns,making their treatment extremely difficult.Available wound care solutions only cater to superficial wounds,and untreated tunneling wounds pose major health concerns.This study aims to fulfill this challenge by fabricating tunnel wound fillers(TWFs)made of natural polymers that mimic the dermal extracellular matrix.In this study,cellulose microfibers(CMFs)derived from banana stem and fish skin-derived collagen were used to formulate bio-inks with varying CMF contents(25,50,and 75 mg).Tri-layered(CMFs,primary and secondary collagen coatings),drug-eluting(Baneocin),and cell-laden(human mesenchymal stem cells)TWFs were three-dimensional(3D)-printed and extensively characterized.CMFs showed the most suitable rheological properties for 3D printing at 50 mg concentration.The Alamar Blue data showed significantly increased cell proliferation from Day 1 to Day 7,and scratch tests used to evaluate in vitro wound healing revealed that the best coverage of the wound area was achieved using CMFs in combination with collagen and alginate.Finally,the TWF showed promising capability and tunability in terms of wound shape and size upon testing on a chicken tissue model.The results demonstrate the tremendous potential of TWFs in treating deep tunneling wounds with unique advantages,such as patient-specific customization,good wound exudate absorption capability while releasing wound healing drugs,and the inclusion of stem cells for accelerated healing and tissue regeneration.

Study on the effect of Shixiang plaster on the expression of CD31,serum FN,and VEGF in a rat model with chronic wounds

Background:Chronic wounds pose a significant surgical challenge,often requiring traditional treatments with limited efficacy.This study explores the promising impact of Shixiang plaster,a classic Chinese ointment,on wound healing.We investigated the cluster of differentiation 31(CD31)expression,serum fibronectin(FN),and vascular endothelial growth factor(VEGF)levels in SPF rats with induced wounds to elucidate the mechanism behind Shixiang plaster’s effectiveness.We investigated the effect and explored the role of Shixiang plaster on the expression of CD31,serum FN,and VEGF in chronic wounds.Methods:The study involved 36 SPF rats divided into model,rb-bFGF,and Shixiang plaster groups.Penicillin was injected into the rats before modelling for 3 days to prevent infection.The skin was excised 2 cm below the horizontal line of the inferior border of the shoulder bone in the middle of the rat column up to the deep fascial layer and inoculated with a certain concentration of Staphylococcus aureus;the wound was covered aseptically for 3 days.The trauma area of the rats was observed at 3,7,and 14 days,respectively.Histopathology was observed using haematoxylin eosin and Masson staining.CD31 expression was detected using immunohistochemistry staining.FN and VEGF expression was detected using serum ELISA.Statistical analyses were carried out by the method of SPSS.Results:Regarding wound morphology,at 3 days,the recovery area of the Shixiang plaster group was larger than that of the other two groups,at 7 days,the wound healing rate of the Shixiang plaster group was significantly higher,and at 14 days,the wounds of the Shixiang plaster group had been mostly healed,with a healing rate of 98.3%.Haematoxylin eosin staining revealed a large amount of granulation tissue at 3 days in the Shixiang plaster group,and the epidermal scales disappeared at 14 days,with thinner epidermal thickness at 1 lesion and a large reduction in inflammatory cell infiltration.Masson staining showed that at 3,7,and 14 days,blue staining was the most abundant and deeper in the Shixiang plaster group,with richer collagen and a compact tissue matrix.Immunohistochemical testing showed strong positive expression of CD31 in the Shixiang plaster group,with abundant neovascularisation and large official lumens extending towards the surface of the wound.Statistically significant elevated expression of FN at 7 and 14 days was determined by ELISA in the Shixiang plaster group,and VEGF expression was significantly increased at 7 days,but expression had been expressed at a low level at 14 days.Conclusion:Shixiang plaster exhibits remarkable efficacy in healing chronic wounds.The proposed mechanism involves FN’s promotion of angiogenesis and cell proliferation,VEGF’s impact on angiogenesis and inflammation,and CD31’s regulatory role in inhibiting inflammation while promoting angiogenesis.

Enhancing the vertical resolution of lunar penetrating radar data using predictive deconvolution

The Yutu-2 rover onboard the Chang’E-4 mission performed the first lunar penetrating radar detection on the farside of the Moon.The high-frequency channel presented us with many unprecedented details of the subsurface structures within a depth of approximately 50 m.However,it was still difficult to identify finer layers from the cluttered reflections and scattering waves.We applied deconvolution to improve the vertical resolution of the radar profile by extending the limited bandwidth associated with the emissive radar pulse.To overcome the challenges arising from the mixed-phase wavelets and the problematic amplification of noise,we performed predictive deconvolution to remove the minimum-phase components from the Chang’E-4 dataset,followed by a comprehensive phase rotation to rectify phase anomalies in the radar image.Subsequently,we implemented irreversible migration filtering to mitigate the noise and diminutive clutter echoes amplified by deconvolution.The processed data showed evident enhancement of the vertical resolution with a widened bandwidth in the frequency domain and better signal clarity in the time domain,providing us with more undisputed details of subsurface structures near the Chang’E-4 landing site.

Non-Hodgkin's lymphoma involving chronic difficult-to-heal wounds:A case report

BACKGROUND Non-Hodgkin's lymphoma(NHL)is a malignant tumor that originates from the lymphoid tissues and can potentially affect numerous organs within the body.Among these,the skin stands out as one of the primary sites affected by NHL,often presenting with multiple extra-nodal manifestations.In this report,we present an unusual case of NHL involving chronic wounds in the lower extremities that were difficult to heal.The scars were successfully treated using radiotherapy in combination with extended excision debridement and peroneal artery perforator flap grafting,resulting in satisfactory outcomes.CASE SUMMARY A 19-year-old male patient presented with ulceration of the skin on the left calf near the ankle accompanied by purulent discharge.Subsequent pathologic biopsy confirmed a diagnosis of NHL(extranodal NK/T-cell lymphoma,nasal type).Initial treatment comprised local radiotherapy and wound care;however,the wound exhibited prolonged non-healing.Consequently,the patient underwent a series of interventions including radiotherapy,wound enlargement excision debridement,and peroneal artery perforator flap grafting.Ultimately,successful healing was achieved with favorable postoperative outcomes characterized by good texture of the flap without any signs of rupture or infection.CONCLUSION The combination of radiotherapy,wound enlargement excision debridement,and peroneal artery perforator flap grafting may present a favorable treatment modality for chronic non-healing lower leg wounds resulting from NHL.

The research status of continuous nursing of patients with chronic wounds is reviewed.Since the research on continuous nursing of chronic wound patients in China is still in the initial stage,if necessary,learn from foreign experience,improve relevant systems,develop corresponding evaluation tools,actively implement telemedicine,and carry out hospital-community linkage models,etc.to provide high-quality nursing services for patients with chronic wounds.

Ballistic performance of spherical fragments penetrating PCrNi3MoV target plates

PCrNi3MoV steel is a medium-carbon,low-alloy quenched and tempered steel that finds its applications in military gun barrels due to the high wear resistance and ablation resistance.To study the penetration and failure modes of PCrNi3MoV plates impacted by tungsten spheres,tungsten spheres of various diameters(5 mm,8 mm,and 10 mm)were used to impact PCrNi3MoV steel plates with thicknesses of 6 mm,9 mm,and 14 mm.The penetration performance of the spheres was analyzed for different velocities,and the ultimate penetration velocity of the plate was obtained.It was found that the primary failure modes of the PCrNi3MoV plate were compression pitting failure and shear failure.Using the dimensional analysis method,a relationship between the bulge height of the steel plate and the fragment velocity,an equation for the ultimate penetration velocity,and a relationship between the target penetration energy and the fragment velocity were obtained.Then,a projectile-target action index was proposed to describe the process of tungsten spheres with different velocities impacting target plates.The results suggested that under the same thickness of the target plate,a larger-diameter fragment required more kinetic energy to obtain the same ultimate penetration effect as a smaller-diameter fragment.The equations obtained through dimensional analysis predicted values that agreed well with experimental values,indicating that these equations can be applied to engineering applications.

Transplantation of a pectoralis major flap for the repair of myiasis wounds

Myiasis is a disease caused by the invasion and colonization of human tissues and organs by the larvae of flies.This is manifested by the formation of necrotic tissue in the lesion,the colonization of fly eggs and the spread of fly larvae.This disease is mostly found in areas with poor sanitary conditions.Poor wound care,necrotic tissue formation,reduced immunity,and frequent contact with flies are risk factors for this disease.Myiasis can be divided into obligate and facultative parasitism,^([1])while some scholars have classified myiasis according to its location.^([2])In addition,some cases of myiasis are secondary to wound infection or poor surgical maintenance.^([3,4]).

Platelet-rich plasma treatment for chronic wounds:A case report and literature review

BACKGROUND Wound healing is a complicated process that can be heavily influenced by patient comorbidities,in some cases leading to a chronic non-healing wound.Evidence presented in the medical literature supporting the clinical use of autologous platelet-rich plasma(PRP)in treatment of such wounds is becoming increasingly compelling.Mechanisms involved include complex interactions between the patient’s thrombocytes,cytokines,and growth factors.CASE SUMMARY We present a case of a 72-year-old male patient with a long-standing chronic wound and multiple comorbidities.Over the course of more than 7 months,the patient was unsuccessfully treated with all routinely used measures,including different dressing approaches.Multiple antibiotic regimens were administered for wound infection,with repeated evaluation of microbiological swab results.Finally,after three PRP applications,the wound showed clinical improvement with complete restitution of the epithelial layer of the skin.CONCLUSION PRP treatment may be beneficial to reduce healing time in chronic wounds.

Late corneal ectasia after penetrating and deep anterior lamellar keratoplasty for keratoconus

AIM:To investigate tomographic features of late corneal ectasia after keratoplasty for keratoconus and compare penetrating keratoplasty(PK)and deep anterior lamellar keratoplasty(DALK)in terms of incidence,time of onset and risk factors of corneal ectasia.METHODS:Sixty eyes with PK and 30 eyes with DALK operated between 1999 and 2021 were analyzed.Final Pentacam scans were evaluated together with vision and previous topographies.Main outcome measures were vision,K values,apparent thinning on graft-host cornea and the difference between opposing quadrants in the thinnest point measurements.Anterior segment optic coherence tomography was performed for further evaluation.RESULTS:Mean follow-up was 127.2mo(24–282mo)in PK,and 64.3mo(24–144mo)in DALK.K max was higher in DALK(60.6 vs 56.7 D,P=0.012).Inferior recipient was thinner(595.9μm)in PK than DALK(662.2μm,P=0.021),due to longer follow-up.Overall corneal ectasia rate was 20.0% within 24y.Ectasia rate was the same(6.7%)in DALK 2/30 and in PK 4/60 in 10y and 13.3%in 12y(4/30 and 8/60,respectively).It increased to 23.3%(14/60)in PK over 24y.While ectasia was not seen before 7y in PK,it could be seen in DALK starting from the 5^(th) year.The intervals between keratoplasty and ectasia were 144.5mo in PK and 99mo in DALK.Inferior recipient was significantly thinner in 18 eyes with ectasia(502.7μm)compared to 76 non-ectasia(649.1μm,P=0.000).Inferior graft was thinner(561.0 vs 620.4μm,P=0.006),K max(63.3 vs 56.5 D,P=0.000),and anterior elevation was higher in ectasia(89.1 vs 48.6μm,P=0.002).Accelerated crosslinking was performed on 5 eyes.CONCLUSION:Inferior-superior recipient and inferior graft thinning on tomography,with high K max and anterior elevation emerge as the most reliable criteria for the diagnosis of late ectasia.The incidence of corneal ectasia increases with the time.

Nanoskin®-ACT—The Impact of Natural Membrane & Soft with Chronic and Untreated Wounds

Bacterial cellulose (BC) is a versatile biomaterial with unique properties that make it promising for various biomedical applications, including wound healing. The extracellular matrix (ECM) plays a crucial role in wound healing, providing a structural scaffold and signaling cues for cell migration and proliferation. This study investigates the potential of BC as a scaffold for ECM production and its effect on in vivo wound healing. In this work, the bacterial cellulose fermentation process is modified by the addition of Green Propolis and Usnic acid to the culture medium and natural materials before the bacteria are inoculated. In vivo behaviour using natural membranes for regenerative medicine is presented and it is in edit. Overall, our findings demonstrate the potential of BC as a scaffold for ECM production and its beneficial effects on in vivo wound healing. BC-based dressings may offer a novel approach to promoting wound healing and tissue regeneration in clinical settings. Further studies are warranted to optimize BC-based therapies and explore their full potential in regenerative medicine.

Steel bar penetrating cervical spinal canal without neurological injury:A case report

BACKGROUND We report a rare case of cervical spinal canal penetrating trauma and review the relevant literatures.CASE SUMMARY A 58-year-old male patient was admitted to the emergency department with a steel bar penetrating the neck,without signs of neurological deficit.Computed tomography(CT)demonstrated that the steel bar had penetrated the cervical spinal canal at the C6–7 level,causing C6 and C7 vertebral body fracture,C6 left lamina fracture,left facet joint fracture,and penetration of the cervical spinal cord.The steel bar was successfully removed through an open surgical procedure by a multidisciplinary team.During the surgery,we found that the cervical vertebra,cervical spinal canal and cervical spinal cord were all severely injured.Postoperative CT demonstrated severe penetration of the cervical spinal canal but the patient returned to a fully functional level without any neurological deficits.CONCLUSION Even with a serious cervical spinal canal penetrating trauma,the patient could resume normal work and life after appropriate treatment.

Management of Penetrating Cranioencephalic Trauma Caused by Sharp Metal Objects—Therapeutic and Evolutionary Aspects: 12 Cases at the Renaissance University Hospital in N’Djamena

Introduction: Cranioencephalic trauma caused by bladed weapons is rare, and that caused by sharp objects is exceptional. The aim of our study was to describe the clinical, therapeutic and evolutionary aspects. Materials and method: This was a descriptive and analytical study over a 48-month period at CHU la Renaissance from January 1, 2018 to December 31, 2021, concerning patients admitted for penetrating cranioencephalic trauma by pointed object. Results: Twelve cases, all male, of penetrating cranioencephalic sharp-force trauma were identified. The mean age was 34 ± 7 years, with extremes of 11 and 60 years. Farmers and herders accounted for 31% and 25% of cases respectively. The average admission time was 47 hours. Brawls were the circumstances of occurrence in 81.2% of cases. Knives (33%), arrows (25%) and iron bars (16.6%) were the objects used. Altered consciousness was present in 43.8% of cases, and focal deficit in 50%. Scannographic lesions were fracture and/or embarrhment (12 cases), intra-parenchymal haematomas (6 cases) and presence of object in place (4 cases). Surgery was performed in 11 patients. Postoperative outcome was favorable in 9 patients. After 12 months, 2 patients were declared unfit. Conclusion: Penetrating head injuries caused by sharp objects are common in Chad. Urgent surgery can prevent disabling after-effects.

Delayed Pseudoaneurysms of Vertebral Artery Post Penetrating Trauma: A Case Report

Objective: Vascular injuries usually present immediately after the penetration, but the delayed onset of vascular symptoms caused by vessel dissection or aneurysm after a traumatic event is extremely rare. Vertebral artery injury is a low-frequency but high-mortality injury. We aim to report evidence of delayed onset of vascular symptoms following penetrating trauma in the neck. Materials and Methods: A case report. Results: A 19-year-old boy was referred to our hospital and complained of a mass in the right part of his neck (right mandibular angle). He gave a history of penetrating trauma to his neck 2 months ago. The mass was expanding during these 2 months and doesn’t respond to antibiotic therapy. In the examination, 3 × 3 cm, firm, nonmobile, and without tenderness and pain mass was palpated in the second level of his neck. Doctors ordered a Doppler sonography in the hospital where a yin-yang pattern was reported. A 36 × 43 × 40 mm heterogeneous, solid, and hypodense area close to C1-C2-C3 with vascular flow was discovered in the right submandibular area after computed tomography (CT)-angiography. The patient was referred to an interventional neurologist for angiography and due to the lack of flow at the distal of the V3 segment, he decided to sacrifice this artery by two coils. Conclusion: Penetrating neck injuries are usually asymptomatic, but these injuries are often accompanied by hemorrhage, neurological symptoms, dysphagia, odynophagia, and windpipe. Penetrating lesions of the vertebral artery are rare and very difficult to diagnose. Also, these lesions are challenging for surgeons due to complex anatomy and difficult surgical exposure. So, endovascular treatment was used to treat the patient.

Diagnosis and treatment of penetrating anorectal wounds

Objective： To research the diagnosis and effective treatment of penetrating anorectal wounds. Methods： Retrospective analysis was done in 16 cases of penetrating anorectal wounds from 1985 to 2004. Dehridement and suture of anorectal and vesical wounds, effective diversion of fecal and urinary stream and sufficient presacral drainage were performed in all cases. Results ： All the 16 cases were cured. Among them, 2 cases with infection in presacral space were cured by sufficient drainage after operation, one case was cured by secondary repair after anal sphincter was repaired unsuccessfully and one case with rectovesical fistula was cured with conservative treatment. None of them suffered from complications such as anal stenosis, dysuria or importence etc. Conclusions： For penetrating anorectal wound, to master early recognition of concomitant injures, to select appropriate surgical intervention and to strengthen perioperative treatment are the keys to improve the curative effects.
