Pediatric cerebrovascular trauma: Incidence, management, and outcomes.

BACKGROUND: Pediatric cerebrovascular trauma (CVT) is rare. There is an increasing use of endovascular management in vascular trauma. We studied the incidence, management, and outcomes of CVT in the pediatric population using the NTDB (National Trauma Data Bank). METHODS: The NTDB was queried for CVT in patients less than 18 years of age over a recent three-year period (2017-2019). Demographics, injury mechanism, type and location, Glasgow Coma Score (GCS), length of stay (LOS), surgical approach (open vs endovascular), and morbidity/mortality were evaluated. Statistical analysis included χ2 and student's t-tests or Fisher's exact tests where appropriate. RESULTS: Of 386,918 pediatric trauma cases, 1536 (0.4%) suffered 1821 CVT. Blunt trauma accounted for 69.3%. Patients were predominantly male (65.4%) and white (57.5%), with an mean age of 14 years. There were 998 (55%) carotid artery injuries, including 846 common/internal carotid and 145 external carotid. Other vessel injuries included 141 (11%) intracranial carotid, 571 (31%) vertebral artery and 252 (14%) jugular vein. Mean number of vessels injured was 1.2. Motor vehicle trauma was most common (49.3%) followed by firearm injury (21%). The mean GCS was 11, and mean total LOS was 11.3 days. Majority of interventions were performed in an open fashion (65.7%), whereas 29.7% were performed endovascularly. Stroke rate was 3.1%. Patients with multiple vascular injuries had an overall mortality of 29% (p<0.0001). CONCLUSION: While not accorded as much importance as blunt injury, penetrating CVT comprises of 30% of injuries. Nearly 1/3rd of all cases needing surgical intervention were managed with endovascular techniques. LEVEL OF EVIDENCE: III.

Contemporary outcomes of traumatic popliteal artery injury repair from the popliteal scoring assessment for vascular extremity injury in trauma study.

OBJECTIVE: Traumatic popliteal artery injuries are associated with the greatest risk of limb loss of all peripheral vascular injuries, with amputation rates of 10% to 15%. The purpose of the present study was to examine the outcomes of patients who had undergone operative repair for traumatic popliteal arterial injuries and identify the factors independently associated with limb loss. METHODS: A multi-institutional retrospective review of all patients with traumatic popliteal artery injuries from 2007 to 2018 was performed. All the patients who had undergone operative repair of popliteal arterial injuries were included in the present analysis. The patients who had required a major lower extremity amputation (transtibial or transfemoral) were compared with those with successful limb salvage at the last follow-up. The significant predictors (P < .05) for amputation on univariate analysis were included in a multivariable analysis. RESULTS: A total of 302 patients from 11 institutions were included in the present analysis. The median age was 32 years (interquartile range, 21-40 years), and 79% were men. The median follow-up was 72 days (interquartile range, 20-366 days). The overall major amputation rate was 13%. Primary repair had been performed in 17% of patients, patch repair in 2%, and interposition or bypass in 81%. One patient had undergone endovascular repair with stenting. The overall 1-year primary patency was 89%. Of the patients who had lost primary patency, 46% ultimately required major amputation. Early loss (within 30 days postoperatively) of primary patency was five times more frequent for the patients who had subsequently required amputation. On multivariate regression, the significant perioperative factors independently associated with major amputation included the initial POPSAVEIT (popliteal scoring assessment for vascular extremity injury in trauma) score, loss of primary patency, absence of detectable immediate postoperative pedal Doppler signals, and lack of postoperative antiplatelet therapy. Concomitant popliteal vein injury, popliteal injury location (P1, P2, P3), injury severity score, and tibial vs popliteal distal bypass target were not independently associated with amputation. CONCLUSIONS: Traumatic popliteal artery injuries are associated with a significant rate of major amputation. The preoperative POPSAVEIT score remained independently associated with amputation after including the perioperative factors. The lack of postoperative pedal Doppler signals and loss of primary patency were highly associated with major amputation. The use of postoperative antiplatelet therapy was inversely associated with amputation, perhaps indicating a protective effect.

Open vs Endovascular Treatment of Traumatic Peripheral Arterial Injury: Propensity Matched Analysis.

BACKGROUND: Arterial injuries occur in the setting of blunt and penetrating trauma. Despite increasing use, there remains a paucity of data comparing long-term outcomes of endovascular vs open repair management of these injuries. The aim of our study was to compare outcomes and readmission rates of open vs endovascular repair of traumatic arterial injuries. STUDY DESIGN: The National Readmission Database (2011-2014) was queried for all adult (age ≥ 18 y) patients presenting with peripheral arterial (axillary, brachial, femoral, and popliteal) injuries. Patients were stratified into 2 groups based on intervention: open vs endovascular approach. Propensity score matching (1:2 ratio) was performed. Outcomes measures were complications, length of stay (LOS), 30-day readmission, and cost of readmission. RESULTS: A matched cohort of 786 patients was obtained (endovascular: 262, open: 524). Mean age was 45 ± 17 years, and 79% were males. Median LOS was 4 (range 2-6) days for the endovascular group vs 3 (range 2-5) days for the open group (p < 0.01). The endovascular group had higher rates of seroma (4% vs 2%; p = 0.04) and arterial thrombosis (13% vs 7%; p < 0.01) during index hospitalization. Patients who underwent endovascular repair had higher 30-day readmission (11% vs 7%; p = 0.03) and a higher 30-day open-reoperation rate (6% vs 2%; p < 0.01). On subanalysis of the patients who were readmitted, the median cost of each readmission was higher in the endovascular group $47,000 ($27,202-$56,763) compared with $21,000 ($11,889-$43,503) in the open group. CONCLUSIONS: Endovascular repair for peripheral arterial injuries was associated with higher rates of in-hospital complications, readmissions, and costs. As this new technology continues to undergo refinement, a thorough re-evaluation of its indications, risks, and benefits is warranted.

Five-Year Management of Vascular Injuries of the Extremities in the "Real-World" Setting in Northeastern Greece: The Role of Iatrogenic Traumas.

BACKGROUND: Vascular trauma comprises a diagnostic and surgical challenge. Aim of this study was to present the vascular traumas treated in our Tertiary Hospital during the last 5 years. METHODS: We retrospectively reviewed the surgical records of our vascular department and documented the site and type of vascular injuries of the extremities along with the concurrence of musculoskeletal injuries. The type and outcome of surgical interventions were also recorded. RESULTS: Fifty-eight cases of vascular trauma were recorded (39 in the upper and 19 in the lower extremities). Overall, iatrogenic traumas accounted for 41.3% of cases. The arterial injuries of the upper limb were blunt and penetrating in 27% and 67%, respectively. The most affected artery in the upper limb was the radial artery (37.8%), followed by the ulnar artery (27%) and the brachial artery (24.3%). Orthopedic injuries were recorded in 19% of patients. Management involved simple revascularization, bypass operations, patch arterioplasty and endovascular management in 48.7%, 33.3%, 5.1%, and 5.1%, respectively. The most affected site in the lower extremity was the common femoral artery (36.8%) followed by the popliteal artery (21%). Bone fractures were reported in 5 cases (26.3%). The surgical management involved bypass, simple revascularization, patch arterioplasty in 42.1%, 26.3%, and 21%, respectively. Endovascular management was performed in 10.5%. CONCLUSIONS: A considerable percentage of iatrogenic vascular injuries was recorded, affecting both the upper and lower limbs. Despite the trend toward centralization of vascular services, a basic service of vascular surgery should be available in most sites to ensure that patients with vascular injuries receive fast and appropriate care.

Lower extremity vascular injuries caused by firearms have a higher risk of amputation and death compared with non-firearm penetrating trauma.

OBJECTIVE: Firearm injuries have traditionally been associated with worse outcomes compared with other types of penetrating trauma. Lower extremity trauma with vascular injury is a common presentation at many centers. Our goal was to compare firearm and non-firearm lower extremity penetrating injuries requiring vascular repair. METHODS: We analyzed the National Inpatient Sample from 2010 to 2014 for all penetrating lower extremity injuries requiring vascular repair based on International Classification of Diseases, Ninth Revision codes. Our primary outcomes were in-hospital lower extremity amputation and death. RESULTS: We identified 19,494 patients with lower extremity penetrating injuries requiring vascular repair-15,727 (80.7%) firearm injuries and 3767 (19.3%) non-firearm injuries. The majority of patients were male (91%), and intent was most often assault/legal intervention (64.3%). In all penetrating injuries requiring vascular repair, the majority (72.9%) had an arterial injury and 43.8% had a venous injury. Location of vascular injury included iliac (19.3%), femoral-popliteal (60%), and tibial (13.2%) vascular segments. Interventions included direct vascular repair (52.1%), ligation (22.1%), bypass (19.4%), and endovascular procedures (3.6%). Patients with firearm injuries were more frequently younger, black, male, and on Medicaid, with lower household income, intent of assault or legal action, and two most severe injuries in the same body region (P < .0001 for all). Firearm injuries compared with non-firearm injuries were more often reported to be arterial (75.5% vs 61.9%), to involve iliac (20.6% vs 13.7%) and femoral-popliteal vessels (64.7% vs 39.9%), to undergo endovascular repair (4% vs 2.1%), and to have a bypass (22.5% vs 6.5%; P < .05 for all). Firearm-related in-hospital major amputation (3.3% vs 0.8%; P = .001) and mortality (7.6% vs 4.2%; P = .001) were higher compared with non-firearm penetrating trauma. Multivariable analysis showed that injury by a firearm source was independently associated with postoperative major amputation (odds ratio, 4.78; 95% confidence interval, 2.07-11.01; P < .0001) and mortality (odds ratio, 1.74; 95% confidence interval, 1.14-2.65; P = .01). CONCLUSIONS: Firearm injury is associated with a higher rate of amputation and mortality compared with non-firearm injuries of the lower extremity requiring vascular repair. These data can continue to guide public health discussions about morbidity and mortality from firearm injury.

Assessment of the "Weekend Effect" in Lower Extremity Vascular Trauma.

BACKGROUND: Studies suggest that patients admitted on weekends may have worse outcomes as compared with those admitted on weekdays. Lower extremity vascular trauma (LEVT) often requires emergent surgical intervention and might be particularly sensitive to this "weekend effect." The objective of this study was to determine if a weekend effect exists for LEVT. METHODS: The National and Nationwide Inpatient Sample Database (2005-2014) was queried to identify all adult patients who were admitted with an LEVT diagnosis. Patient and hospital characteristics were recorded or calculated and outcomes including in-hospital mortality, amputation, length of stay (LOS), and discharge disposition were assessed. Independent predictors of outcomes were identified using multivariable regression models. RESULTS: There were 9,282 patients admitted with LEVT (2,866 weekend admissions vs. 6,416 weekday admissions). Patients admitted on weekends were likely to be younger than 45 years (68% weekend vs. 55% weekday, P < 0.001), male (81% weekend vs. 75% weekday, P < 0.001), and uninsured (22% weekend vs. 17% weekday, P < 0.001) as compared with patients admitted on weekdays. There were no statistically significant differences in mortality (3.8% weekend vs. 3.3% weekday, P = 0.209), amputation (7.2% weekend vs. 6.6% weekday, P = 0.258), or discharge home (57.4% weekend vs. 56.1% weekday, P = 0.271). There was no clinically significant difference in LOS (median 7 days weekend vs. 7 days weekday), P = 0.009. On multivariable regression analyses, there were no statistically significant outcome differences between the groups. CONCLUSIONS: This study did not identify a weekend effect in LEVT patients in the United States. This suggests that factors other than the day of admission may be important in influencing outcomes after LEVT.

Is endovascular repair the first choice for all blunt aortic injury? A real-world assessment.

Blunt thoracic aortic injury (BTAI) represents an infrequently encountered but lethal traumatic injury. Minimal aortic injuries are appropriately treated by medical management, while more severe injuries require endovascular or open repair. Rapidly evolving endovascular technology has largely supplanted open repair as first line operative intervention, however, the complexity of the severely injured blunt trauma patient can complicate management decisions. The development and implementation of an optimal consensus grading system and treatment algorithm for the management of BTAI is necessary and will require multi-institutional study.

Multiple Ligament Injured Knee: Initial Assessment and Treatment.

The multiple ligament injured knee (knee dislocation) is oftentimes part of a multisystem injury complex that can include injuries not only to knee ligaments but also to blood vessels, skin, nerves, bones (fractures), head, and other organ system trauma. These additional injuries can affect surgical timing for knee ligament reconstruction and also affect the results of treatment. This article presents the author's approach and experience to the initial assessment and treatment of the multiple ligament injured (dislocated) knee.

Derivation and validation of thoracic sarcopenia assessment in patients undergoing thoracic endovascular aortic repair.

OBJECTIVE: Sarcopenia, as assessed by computed tomography (CT)-based measurements of muscle mass, is an objective and patient-specific indicator of frailty, which is an important predictor of operative morbidity and mortality. Studies to date have primarily focused on psoas-defined sarcopenia, which may not be valid among patients with thoracic aortic disease. Using psoas sarcopenia as the reference for sarcopenia, the purpose of this study was to create and to validate a new thoracic-level method of measuring sarcopenia as a novel method to assess frailty among patients undergoing thoracic endovascular aortic repair. METHODS: Prospectively collected data of patients undergoing thoracic endovascular aortic repair for thoracic aortic dissection, aneurysm, or injury using a conformable thoracic graft were reviewed. Patients with preoperative abdominal and thoracic CT imaging were included. Thoracic muscle mass was measured on axial images at the T12 level using our newly established standardized computer-assisted protocol. Psoas sarcopenia was measured at the L3 level using standard methods. Optimal sex-specific diagnostic T12 measurements were determined by receiver operating characteristic (ROC) curve analysis. A subset of scans were reviewed in duplicate by two trained observers and intraobserver and interobserver reliability tested by intraclass correlation coefficient. Agreement between T12 and L3 sarcopenia was tested by Cohen κ (scale, 0-1). RESULTS: There were 147 patients included for analysis, including 34 dissection, 80 trauma, and 33 aneurysm patients. ROC curve analysis yielded sarcopenic cutoff values of 106.00 cm2/m2 for women and 110.00 cm2/m2 for men at the T12 level. Based on ROC curve analysis, overall accuracy of T12 measurements was high (area under ROC curve, 0.91 for men and 0.90 for women). Quantitative interobserver and intraobserver reliability yielded excellent intraclass correlation coefficient values (>0.95). Qualitative interobserver reliability yielded nearly perfect Cohen κ values (>0.85). Qualitative intraobserver reliability of calculating sarcopenia at both the T12 and L3 levels was fair for both readers (0.361 and 0.288). There was additionally a general correlation between changes in muscle area at L3 with changes at T12 during 48 months. CONCLUSIONS: Thoracic sarcopenia can be readily and reliably reproduced from CT-derived measurement of T12-level muscle area. This approach may be used as an alternative method to objectively define sarcopenia in patients without abdominal CT imaging. Future studies to assess the predictability of thoracic vs abdominal sarcopenia on postoperative outcomes will enhance the utility of these tools.

Failure of lumbar disc surgery: management by fusion or arthroplasty?

PURPOSE: To analyze and clarify conflicting aspects of fusion and total disc replacement (TDR) surgery in literature. METHOD: Using keywords, 23 literature reviews, 41 studies accepted by "importance criteria" from the Internet, and 16 articles "published in 2018" were chosen. Altogether 80 studies. RESULTS: General assessment was mentioned as affirmative for TDR in 40 papers, five were negative, 24 without clear decision. Long term results TDR seven affirmative, four nondecisive. Comparison to fusion (general, ALIF, 3600, BAK cage) 18 found as better, nine equal, one nondecisive. Complications TDR 3-50%. Adjacent disc degeneration disease recognized in 14 papers, denied existence in four. Cost-benefit effective in three papers comparing to fusions, ALIF, 3600. Nonimbursement from the state mentioned as problem in three papers. Salvage surgery seven papers, rare but extremely problematic. Anterior approach 16 challenging surgery, one 10% minor, one 38.5% transient complications, one 1.8% retrograde ejaculations, one 6.6% vascular injuries, two access surgeon needed. Construct judgment two no importance, 22 wear and durability problems, two inadequate biomechanics and biomaterials, three construct and lateral approach. Impact of TDR upon spine surgery is decreasing, currently is less than 2%. CONCLUSION: It is concluded that problems with anterior surgery, imbursement policy, and potential problems with salvage surgery are major reasons for loosing popularity of TDR surgery.

Incidence and management of arterial injuries during pancreatectomy.

PURPOSE: The incidence of intraoperative arterial injury during pancreatectomy is not well described. This study aims to evaluate the incidence, management, and outcome of arterial injuries during pancreatectomy. METHODS: This is a retrospective study of 1535 consecutive patients undergoing pancreatectomy between 2006 and 2016 at Oslo University Hospital. The type of arterial injury and potential contributing factors were analyzed. Short-term outcomes were compared between patients with arterial injury and patients undergoing a planned arterial resection due to tumor involvement. RESULTS: Arterial injury was diagnosed in 14 patients (incidence 0.91%), while planned arterial resection was performed in 22 patients. The injuries were located in the superior mesenteric artery (n = 5), right hepatic artery (n = 5), common hepatic artery (n = 2), left hepatic artery (n = 1), and celiac trunk (n = 2). The artery was reconstructed in all except one patient. In 11 patients with injury, peripancreatic inflammation, aberrant arterial anatomy, close relationship between tumor and injured artery, or a combination of the three were found. Median estimated blood loss was 1100 ml in both groups. Rate of severe complications (≥ Clavien grade IIIa), comprehensive complication index, and 90-day mortality for patients with intraoperative arterial injury vs planned arterial resection were 43 vs 45% (p = 0.879), median 35.9 vs 21.8 (p = 0.287), and 14.3 vs 4.5% (p = 0.551), respectively. CONCLUSION: Arterial injury during pancreatectomy is an infrequent and manageable complication. Early recognition and primary repair in order to restore arterial liver perfusion may improve outcome. However, the morbidity is high and comparable to patients undergoing a planned arterial resection.

Surgical Management of Musculoskeletal Trauma.

Musculoskeletal injuries cause a significant burden to society and can have a considerable impact on patient morbidity and mortality. It was initially thought that these patients were too sick to undergo surgery and later believed that they were too sick not to undergo surgery. The pendulum has subsequently swung back and forth between damage control orthopedics and early total care for polytrauma patients with extremity injuries and has settled on providing early appropriate care (EAC). The decision-making process in providing EAC is reviewed in an effort to optimize patient outcomes following severe extremity trauma.

Pediatric vascular injuries: Are we preparing trainees appropriately to meet our needs?

BACKGROUND: There is no required competency for pediatric vascular injury in surgical training. We sought to describe changes over time for surgical specialists operating on pediatric vascular trauma injuries at a pediatric trauma center. METHODS: Charts were retrospectively reviewed for vascular trauma injuries at a freestanding children's hospital between 1993 and 2015. Data were collected on mechanism, injured vessel(s), operation(s) performed, and specialists performing operation. Surgical specialists were compared over time. RESULTS: Ninety-four patients (median age = 12) underwent 101 pediatric vascular trauma operations. There were significant differences in frequency of types of operations (primary repairs, graft repairs, and ligations) performed by pediatric, vascular, and orthopedic surgeons (P < .001). The proportion of operations performed by vascular surgeons increased and those performed by pediatric surgeons decreased significantly over time. CONCLUSIONS: Various surgical specialists manage pediatric vascular trauma. With expansion of integrated residency programs, surgical specialists managing these patients in the future should be trained in both pediatric and vascular surgery.

Complications and revision amputation following trauma-related lower limb loss.

INTRODUCTION: Trauma-related amputations are a common cause of limb loss in the United States. Despite the military and public health impact of trauma-related amputations, distributions of various lower limb amputations and the relative frequency of complications and revision amputations have not been well described. We used the National Trauma Data Bank (NTDB) in order to investigate the epidemiology of trauma-related lower extremity amputations among civilians in U.S. trauma centers. MATERIALS AND METHODS: We conducted a secondary data analysis of the 2011-2012 NTDB research data sets, using means and frequencies to characterize the patient population and describe the distribution of major lower extremity amputations. Multivariable regression models were fit to identify predictors of major post-surgical complications, revision amputation, length of hospitalization, and in-hospital mortality. RESULTS: A total of 2879 patients underwent a major lower extremity amputation secondary to a trauma-related lower limb injury, representing 0.18% of all NTDB trauma admissions from 2011 to 2012. 80.4% were male and 67.6% were white. The three most frequent definitive amputations preformed included trans-tibial (46%), trans-femoral (37.5%), and through foot (7.6%). The average length of hospitalization for all amputees was 22.7days. Patients with at least one revision amputation stayed in the hospital approximately 5.5days longer than patients not needing a revision amputation. 1204 patients (41.8%) required at least one revision amputation. 27.5% of amputees experienced at least one major post-surgical complication. African Americans experienced a 49% higher major post-surgical complication incidence and stayed, on average, 2.5days longer in the hospital compared to whites. Injury severity score, age, hospital teaching status, presence of a crush injury, fracture location, presence of compartment syndrome, and experiencing a major post-surgical complication were all significant predictors of revision amputation. CONCLUSION: We report a high rate of complications and revision amputations among trauma-related lower limb amputees, and identify predictors of surgical outcomes that have not been described in the literature including African American race. Compartment syndrome is a significant predictor of major post-surgical complications, revision amputation, and length of hospitalization.

Patient Experiences of Life Years After Severe Civilian Lower Extremity Trauma With Vascular Injury.

OBJECTIVE: Severe lower limb trauma with arterial injury is often devastating for the individual. Many studies describe how to manage these injuries when they occur. Short-term functional outcome is quite well described, but the patients are often young, and their suffering is physical, mental, and social from a lifelong perspective. The aim of this study was to report patient experiences of their lives several years after their accidents, and to explore mechanisms of how to improve management. METHOD: The Swedvasc registry was searched for participants from 1987 to 2011, living in the region of Uppsala, Sweden. Some amputated participants were added from the Walking Rehabilitation Center. There were five reconstructed patients with an intact limb, and three with amputations. In depth interviews were conducted and systematically analyzed, using A Giorgi's descriptive phenomenological method. RESULTS: Eight patients participated, five with reconstructed and three with amputated limbs. Life affecting functional impairments were described by all patients. The patients undergoing amputation had received more structured follow up and support through the Walking Rehabilitation Center. The satisfaction with the cosmetic result was poorer than expected. All patients had developed strategies of how to cope with their impairments and stated they now lived "normal lives." CONCLUSIONS: Despite substantial physical, psychological, and cosmetic impairments years after severe lower limb trauma, the participants described life as "normal" and mainly satisfactory. Transition to the new situation could have been facilitated by more frequent and continuous follow up after discharge from hospital, in particular among the non-amputated patients who tend to be lost to follow up. Findings also indicate that family members have to be acknowledged, strengthened, and supported.

Racial disparities after vascular trauma are age-dependent.

OBJECTIVE: Different racial disparities exist between white and black all-cause trauma patients depending on their age group; however, the effects of race and age on outcomes after vascular trauma are unknown. We assessed whether the previously described age-dependent racial disparities after all-cause trauma persist in the vascular trauma population. METHODS: Vascular trauma patients were identified from the Nationwide Inpatient Sample (January 2005 to December 2012) using International Classification of Diseases-Ninth Edition codes. Univariable and multivariable analyses were used to compare in-hospital mortality and amputation for blacks vs whites for younger (16-64 years) and older (≥65 years) age groups. RESULTS: Black patients (n = 937) were younger, more frequently male, without insurance, and suffered from more penetrating and nonaccidental injuries than white patients (n = 1486; P < .001). On univariable analysis, blacks had a significantly higher risk of death (odds ratio, [OR], 1.78; 95% confidence interval [CI], 1.16-2.74) and a significantly lower risk of amputation (OR, 0.54; 95% CI, 0.38-0.77), but these differences were not sustained after adjusting for baseline differences between groups. When stratified by age, there were significant racial disparities in mortality and amputation on univariable analysis. After risk adjustment, these differences persisted in the older group (mortality: OR, 5.95; 95% CI, 1.42-25.0; amputation: OR, 4.21; 95% CI, 1.28-13.6; P < .001) but not the younger group (mortality: OR, 1.31; 95% CI, 0.71-2.42; amputation: OR, 0.92; 95% CI, 0.58-1.46; P = not significant). Differences in survival and amputation after vascular trauma appear to be related to a higher prevalence of nonaccidental penetrating injuries in the younger black population. Race was the single greatest predictor of poor outcomes in the older population (P ≤ .008). CONCLUSIONS: Older black patients are nearly five-times more likely to experience death or amputation after vascular trauma than their white counterparts. Contrary to reports suggesting that younger white patients have better outcomes after all-cause trauma than younger black patients, racial disparities among patients with traumatic vascular injuries appear to be confined to the older age group after risk adjustment.

Management of Vascular Injury during Current Peaceful Yemeni Revolution.

BACKGROUND: To provide a complete review of our experience on the observed vascular injuries patterns during contemporary Yemeni revolution, management strategies used in the care of injuries and to highlight lessons learned from that period. METHODS: From February 2011 to January 2012, all casualties evaluated at Yemen International Hospital, were prospectively entered into a database and retrospectively reviewed. Data collected included site, type, and mechanism of vascular injury, associated trauma, type of vascular repair; initial outcome, amputation rate, and complication. RESULTS: Of 2,200 injured patients evacuated from field hospital, vascular injuries occurred in 63 patients, and these patients comprised the study group. Fifty-one (80.9%) patients were wounded by gunshots high velocity, 6 (9.5%) were wounded by gunshots low velocity, and 6 (9.5%) experienced explosive devices injury. Most of injuries 55 (87%) occurred in the extremities 45 (71%) in the lower extremities and 10 (16%) in the upper extremities, 3 (5%) in carotid arteries, 3 (5%) in internal iliac arteries, and 2 (3%) in internal jugular vein. Nearly half 31 (49%) of the patients sustained complex vascular injuries (arterial and venous injuries), isolated arterial injuries 28 (45%), and isolated venous injuries 4 (6%). Twenty (32%) of the patients underwent complete revascularization and 11 (15%) just arterial repair with venous ligation. According arterial management 32 (51%) of patients underwent revascularization with venous graft, 18 (29%) repaired by end-to-end anastomosis, 1 (2%) polytetrafluorethylene, 7 (11%) thrombectomy, and 5 (8%) arterial ligation. Vascular injuries were associated with bony fracture in 33 (52%) of patients. Postoperative wound infection occurred in 9 (14%) patients. Of those, 7 had venous ligation. Secondary amputation and mortality rates during the study period were 3 (5%) and 4 (6%), respectively. CONCLUSIONS: This report represents the first analysis of vascular injuries during contemporary Yemeni revolution in Taiz city. Vascular injuries occurred in 3% of revolution-related injured patients. Our secondary amputation rate of extremities was 5%. Management of arterial repair with autologous vein graft remains the treatment of choice. Ligation of venous injured in a watershed area, such an iliofemoral and popliteal vein should be avoided to prevent leg phlegmasia.
