Management of war-related vascular injuries: experience from the second gulf war

Our experience with blast and gunshot induced traumatic vascular injuries at Somalia's major vascular referral center

Blast and gunshot-induced penetrating traumatic vascular injuries represent a significant portion of patients with vascular trauma in countries where there are higher rates of war-related violence. These injuries are especially challenging in resource-limited countries due to early diagnosis and transfer delays. This report aimed to present our experience regarding the surgical management and outcome of such injuries at a major referral vascular surgery centre in the country. A retrospective descriptive review of 326 patients with blast and gunshot-induced penetrating traumatic vascular injuries managed during a five-year period between April 2018 and April 2023. The demographics, mechanism of injury, type of vascular injury, Anatomical location, time to the operation, length of hospital stay, amount of blood products given, concomitant neuroskeletal injuries, development of Vascular injury associated acute kidney injury, surgical procedures performed and patient outcome were reviewed. In this study, 326 patients with 445 vascular injuries fulfilled the inclusion criteria. Most of the patients were male 92.3%, and the mean age was 28.3 ± 9.9 years. The gunshot mechanism of vascular injury was implicated in 76.1% of the injuries, and explosive-induced injury was 78 (23.9%). 193 (59.2%) of the patients had isolated arterial injuries, 117 (35.9%) patients had combined arterial and venous injuries while 18 (4.9%) patients had isolated venous injuries. The most commonly injured arteries were the femoral artery, followed by Brachial and popliteal artery injuries (26.1%, 23.5% and 19.4%, respectively). The median time to revascularization was 8.8 ± 8.7 h. 46.8% of the patients had Concomitant fractures, while 26.5% had Concomitant nerve injuries. Only three patients had temporary non-heparin-bound shunts during their arrival. The most common surgical intervention in arterial injuries was reversed saphenous vein graft 46.1%. The mortality was 5.8% and 7.7% of the patients needed secondary amputation. The majority of wartime arterial injuries are a result of Blast and gunshot vascular injuries. Frequent need for autologous vein grafts should be considered to manage such injuries. Results are encouraging despite delays in intervention; therefore, all viable limbs should be revascularized, keeping in mind the long-term functionality of the limb.

Combined Supra-Inguinal Fascia Iliaca, Sciatic Nerve, and Posterior Femoral Cutaneous Nerve Blocks in Austere Settings for Hemodynamically Unstable Patients with Vascular Injuries from Weapon Wounds: A Case Series

Purpose

The management of unstable patients with weapon-wounded lower limb vascular injuries presents significant anesthetic challenges. Regional anesthesia blocks, which combine lumbar and sacral plexus blocks, or their respective branches, minimize systemic effects and are deemed appropriate for high-risk patients requiring lower limb surgery. This case series aims to share our preliminary experiences with a combined anesthetic technique-sciatic nerve (SN), posterior femoral cutaneous nerve (PFCN), and supra-inguinal fascia iliaca (SIFI) blocks -in patients sustaining weapon wounds and undergoing lower limb vascular injury repair in austere environments.

Patients and Methods

Seven patients with lower limb vascular injuries resulting from weapons who required surgery at district hospitals supported by the International Committee of the Red Cross were included in this study. Included patients underwent surgery for vascular repair and debridement using a combined nerve block technique involving the SN, PFCN, and SIFI blocks between May and December 2023. The blocks were administered using a 1:1 mixture of 1% lidocaine and 0.5% levobupivacaine.

Results

The combined block technique for the Sciatic Nerve (SN), Posterior Femoral Cutaneous Nerve (PFCN), and the Supra-Inguinal Fascia Iliaca (SIFI) were performed without complications in all patients. Three of the patients received light sedation prior to the initiation of the block procedure. All surgeries were completed successfully without the need for additional analgesics or conversion to general anesthesia.

Conclusion

The combined block technique for the Sciatic Nerve (SN), Posterior Femoral Cutaneous Nerve (PFCN), and the Supra-Inguinal Fascia Iliaca (SIFI) appears to be a safe anesthetic option for unstable or high-risk patients requiring lower limb surgery. Further research with a larger cohort is necessary to validate our findings and to potentially standardize this approach.

Camel-related major vascular injuries: A 20-years' experience

BACKGROUND

Majority of human animal-related injuries in the United Arab Emirates are caused by camels. These may involve major vessels and can be life-threatening. We aimed to study the biomechanism, injured regions, management, and outcome of major camel-related human vascular injuries.

METHODS

We retrospectively studied all patients who were admitted to Al-Ain Hospital with camel-related major vascular injury during January 2001 to January 2020. Studied variables included demography, mechanism of injury, injured structures, clinical presentation, vital signs on arrival, associated injuries, surgical management, ICU stay, length of hospital stay, complications, and outcome.

RESULTS

Seven patients were studied; all were males having a median age of 26 years. Five out of six bite injuries (83%) occured during the camel rutting season. The injuries were severe and life-threatening. A camel bite causes four small elliptical wounds of the canine teeth which resembles two stab wounds of 8 cm long, penetrating deeply and injuring major vessels. Four involved the carotid artery, one the femoral artery and vein, one the external iliac vein and one the aorta which was due to a fall from a camel. Although the standard of surgical care was high, the outcome was poor. Six patients were admitted to the ICU for a median of 5 days. One patient died, one became vegetative, and one had arm paralysis.

CONCLUSIONS

Major camel-related vascular injuries have a poor clinical outcome. This is related to the biomechanism of injury which combines penetrating, crushing and blunt trauma. Neck wounds of camel bites can be closed primarily after debridement.

Combat injuries sustained by troops on counter terrorism and counter-insurgency operations in North east Nigeria: Implications for intervention

Background

Understanding the epidemiology of battlefield casualties is required for plans and coordinated efforts towards improved combat trauma care (CTC) performance and outcome. The engagement of the Armed Forces of Nigeria (AFN) in containing Boko Haram Terrorism (BHT) and insurgency in Northeast Nigeria has increased the risk of combat injuries to the troops. This study determined the characteristics of combat injuries sustained by soldiers on counter terrorism and counter-insurgency operations to contain BHT.

Methods

A retrospective cross-sectional study of combat casualties managed in 7 Division (Field) Hospital, [an equivalent of UN Level 2 facility] Maiduguri, Northeast Nigeria between November 2013 and October 2014. Using data obtained from a designed Operational Casualty Card that contains their sociodemographic characteristics, categorization (as Combat Arm, Combat Support Service, Civ-JTF), nature, mechanism and sites of injury as well as inpatients records. The data were collated and analysed using SPSS version 20.

Results

A total of 209 casualties were treated. The age of the casualties ranged from 18 to 57 years with a mean of 30.6 ± 7.7 years and males constituting 99%. Over two-third (71.3%) casualties had gunshot injuries while 14.3% and 8.1% sustained improvised explosive device (IED) and fragments injuries respectively. Over three-quarter (77.5%) sustained injuries on the upper and lower extremities while 17 (7.7%) and 12 (5.7%) had injuries on thorax/abdomen and head/neck respectively. Nineteen (9.1%) casualties resulted from friendly forces/colleagues.

Conclusion

The study revealed that gunshot and IED/blasts on the extremities were the most frequent mechanism and pattern of injuries sustained with less than a tenth of the casualties resulting from friendly forces. Training health personnel on CTC, deployment of combat lifesavers to improve pre-hospital CTC, employment of skilled Orthopaedic Surgeon and other relevant surgical subspecialties and timely air evacuation of critical cases from the Field Hospital to the Base Hospital are recommended.

Limb-Salvage Outcomes of Arterial Repair Beyond Time Limit at Different Lower-Extremity Injury Sites

Background

The purpose of this study was to analyze the outcomes of revascularization exceeding 12 h after arterial injury at different sites of the lower extremity.

Materal/Methods

From January 2009 to April 2017, 58 patients with 58 lower-limb arterial injuries who underwent revascularization over 12 h after trauma were included in our study. Outcomes measured, including mortality, amputation, complications, and other parameters (gait, length discrepancy, the range of movement of the knee and ankle joint, and muscle wasting) were analyzed.

Results

External iliac artery injury (EIAI) or femoral artery injury (FAI) was affected in 4 patients, superficial femoral artery injury (SFAI) in 18, and popliteal artery injury (PAI) (including proximal gastrocnemius muscle vascular (PGMV) and proximal gastrocnemius muscle vascular [PGMV]) in 36. The median time of arterial injury was 72 h (interquartile range, 59.5). No mortality was found. Amputations were performed in 16 patients due to non-viable limbs, progressing infection, or muscle necrosis. All patients were followed up (median, 52 months; interquartile range, 5.5). Of the 42 limb-salvage patients, most had a limp, muscle wasting, or ankle and knee dysfunctions, and 26 patients with knee or ankle dysfunction underwent secondary surgery.

Conclusions

Although limited recanalization of blood vessels may lead to limb complications or amputations over time, the high success rate of limb salvage still merits the surgeon’s best efforts.

Barriers to managing and delivery of care to war-injured survivors or patients with non-communicable disease: a qualitative study of Palestinian patients' and policy-makers' perspectives

BACKGROUND

Improving access to optimal quality of care is a core priority and ambitious health policy goal in spite of impediments, threats and challenges in Palestine. Understanding the factors that may impede quality of care is essential in developing an effective healthcare intervention for patient with non-communicable disease (NCD) or war-injured survivors.

METHODS

Qualitative interviews were performed using a purposive sampling strategy of 18 political-key informants, 10 patients with NCD and 7 war-injured survivors from different health facilities in Gaza Strip. A semi-structured interview guide was developed for data collection. The interviews were audio recorded and transcribed verbatim. Important field notes of the individual interviews were also reported. Thematic-driven analytic approach was used to identify key themes and patterns.

RESULTS

From the policy maker's perspective, the following important barriers to accessing optimal healthcare for patients with NCD or war-injured survivors' treatment were identified; 1) organizational/structural 2) availability 3) communication 4) personnel/lack of staff 5) financial and political barriers. Patient with NCD or war-injury had similar experiences of barriers as the policy makers. In addition, they also identified socioeconomic, physical and psychological barriers for accessing optimal healthcare and treatment.

CONCLUSIONS

The main perceived barriers explored through this study will be very interesting and useful if they are considered seriously and handled carefully, in order to ensure efficient, productive, cost-effective intervention and delivery of a high-standard quality of care and better disease management.

Surgical restoration of drop-hand syndrome with tendon transfer in patients injured in the Syrian civil war

BACKGROUND

The radial nerve is one of the most common war-related injury sites due to penetrating cutting tool injuries or gunshot wounds, resulting in drop-hand syndrome. The aim of this study was to evaluate the outcomes of tendon transfer in patients with drop-hand syndrome who had been injured in the Syrian Civil War.

METHODS

This level-II, prospective, comparative study included 13 civilians injured in the Syrian Civil War 2015 and 2017. The palmaris longus tendon was used for transfer to the extensor pollicis longus for thumb extension. The pronator teres was transferred to the extensor carpi radialis brevis for wrist extension. The flexor carpi radialis was transferred to the extensor digiti communis for 2nd, 3rd, 4th, and 5th finger extension. All outcomes of thumb abduction and extension, wrist extension, wrist flexion, and finger extension were assessed.

RESULTS

There was a high level of radial nerve injury in all patients included in the study. The time from injury to treatment ranged from 1.5 months to 9 months. The mechanism of injury most commonly observed was a gunshot wound, which was observed in 8 patients (61.5%), followed by a penetrating cutting tool injury (n = 3; 23.1%) and humerus fracture (n = 2; 15.4%).

CONCLUSIONS

In radial nerve injuries, successful results can be achieved with tendon transfer. All patients regained thumb abduction of up to approximately 60°. All the patients were able to bend the wrist, grip, and extend the fingers while in wrist flexion, neutral wrist and wrist extension positions. Although the reason for the radial injury varied, the postoperative outcomes were good for all patients, and the rehabilitation period progressed successfully in patients who underwent tendon transfer repair within 90 days of injury.

Amputação foi necessária em 6,9% e a mortalidade foi 7,93%. Conclusão: distâncias superiores a 200km foram associadas à internação prolongada e maior probabilidade de amputação de membros. Foi encontrada correlação significativa entre a ocorrência de óbito e o fato de haver lesão arterial, lesão vascular na topografia cervical e lesão vascular na topografia torácica.

The burden of war-injury in the Palestinian health care sector in Gaza Strip

Background

War-related injury is a major public health concern, and a leading cause of mortality, morbidity, and disability globally, particularly in low and middle-income countries such as Palestine. Little is known about the burden of war-related injury in the Palestinian context. The objective of this study was to characterize the incidence and pattern of injuries, associated with war in Gaza Strip, from July 8 to August 26, 2014.

Methods

This was a descriptive study based on an injury registry at hospital facilities in the Gaza Strip. A total of 420 victims records from 2014 Gaza war injuries were randomly selected, proportionate to the size of the study population estimated across five Gaza governorates. Simple descriptive statistics were calculated to explore the frequency and percentage distribution of study variables and injury data. A chi-square test (X²) was used. The significance level was derived at p < 0.05. The data were analyzed by IBM SPSS software, version 23.

Results

Males (75.5%) have experienced more war-related injuries than females (24.5%), constituting a male: female ratio of 3.1:1. Almost half (49.5%) of the injured victims were of the age group 20–39, followed by children and adolescents (< 20 years), accounting for 31.4%. More than half of victims were single (53.6%), 44.3% were married and the rest were widowed or divorced. The overall number of injuries was 6.4 per 1000 population, though it varied among regions. North Gaza reported the highest number of injuries (9.0) and Rafah the lowest (4.7) per 1000 population. Blast and explosion were found to be the most common causes of war injuries (72.9%). The highest proportion of injuries were reported in the upper body. Multiple body shrapnel wounds and burns (39.3%) were most frequent. Other types of injuries were multiple organ injury (24.3%), fractures (13.6%), internal organ injury and bleeding (9.8%), amputation (4.5%), abrasions/lacerations and contusions (4.8%), vision or hearing loss or both (1.9%) and respiratory problems (1.9%). The highest percentage of injuries were classified as mild (46.9%), and the rest ranged from moderate-to-severe. Almost 26% of individuals had sustained disability, and most of them had physical/motor impairment.

Conclusion

War-related injuries constitute a major problem to public health discipline and clinical medicine as well. A better surveillance system using ICD codes, and development of a comprehensive electronic data network are necessary to make future research easier and more timely.

Vascular trauma in the Amazon - the challenge of great distances

OBJECTIVE

to evaluate the incidence of unfavorable outcomes in vascular trauma patients and their possible correlation to the distance between the city where the injury was sustained and the hospital where the patient received definitive treatment.

METHODS

descriptive and retrospective study. Data were collected from medical records of patients submitted to surgical procedures for arterial or venous injuries from February 2011 to February 2013 at the only trauma center providing vascular surgery in a vast area of the Amazon region. Trauma date, patient gender and age, mechanism and anatomic topography of injury, surgical management, need for surgical re-intervention, hospitalization period, postoperative complications, mortality and limb amputation rates were analyzed. The incidence of unfavorable outcomes was assessed according to the distance between the city where the vascular injury was sustained and the trauma center.

RESULTS

One hundred seventy-three patients with 255 vascular injuries were analyzed; 95.95% were male (p<0.05), mean age of 28.92 years; 47.4% were caused by firearm projectiles (p<0.05); topographic distribution: 45.66% lower limbs (p<0.05), 37.57% upper limbs, 6.94% abdominal, 5.2% thoracic and 4.62% were cervical vascular injuries; 51.42% of patients required hospitalization for seven days or less (p<0.05); limb amputation was necessary in 15.6% and the overall mortality was 6.36%.

CONCLUSION

distances greater than 200 Km were associated to longer hospitalization period; distances greater than 300 Km were associated to increased limb amputation probability; severe vascular trauma have an increased death probability when patients need to travel more than 200 Km for surgical treatment.
