RESUMEN
BACKGROUND AND OBJECTIVES: Considering the absence of integrated vascular surgery residency programs in Saudi Arabia, and the need for planning training pathways, we aim to identify how many medical students are interested in vascular surgery, and the factors affecting students' opinions on pursuing vascular surgery. MATERIALS AND METHODS: A cross-sectional study was conducted using an online questionnaire that was distributed to medical students nationwide via social media and email. Data were collected from 13 February 2022 to 1 March 2022. RESULTS: A total of 408 students participated. Among them, 152 students were interested in general surgery, of which 103 were considering vascular surgery as a possible future fellowship. However, only 29 out of 408 (7.1%) students picked vascular surgery as their 1st choice. The main motivating factors for students to pursue vascular surgery as a career were: an interest in vascular cases (cardiovascular science), the use of emerging technologies, and the endovascular capabilities of vascular surgeons. The negative factors were simply a preference for another specialty, followed by a lack of experience in vascular surgery. CONCLUSION: This study reveals that only 7.1% of students consider vascular surgery their first choice. Both the lack of vascular surgeons and students' experience in vascular surgery affected awareness levels. Interaction with vascular surgeons through virtual rotations for under-served medical schools and the introduction of vascular sciences within the cardiology blocks during basic science years are recommended strategies.

BACKGROUND: The level of awareness of peripheral artery disease (PAD) in Saudi Arabia, especially among populations at high risk, is not currently well known. Therefore, our objective was to assess the existing level of awareness among patients who are at high risk of PAD, as well as their comprehension of the disease. METHOD: An interview-based cross-sectional study included 1035 participants with risk factors for PAD and collected data on demographics and knowledge domains related to PAD. RESULTS: The statistical analysis was performed using t-tests and ANOVA. Overall, participants exhibited poor knowledge, with a mean score of 5.7 out of 26. The highest scores were observed in the risk factor and preventive measure domains, with means of 1.8 out of 7 and 1.8 out of 6, respectively. The factors associated with higher knowledge scores included older age, male gender, higher education, healthcare profession, interviews in vascular settings, previous awareness of PAD, and prior cardio-cerebrovascular interventions. CONCLUSION: This study underscores the inadequate knowledge of PAD among high-risk individuals. Targeted educational initiatives are essential to bridge this knowledge gap, potentially reducing the burden of PAD-related complications and improving patient outcomes. Efforts should focus on raising awareness about PAD, particularly among high-risk populations.
RESUMEN
Carotid body tumors (CBTs) are rare and mostly benign. Research outcomes usually arise from single-center data. We conducted this study to present the characteristics and outcomes of patients who underwent surgical resection of CBT at our hospital over the past 20 years. In this retrospective review, the records of CBTs in our hospital were reviewed between 1998 and 2021. All patients who underwent CBT resection were included. The follow-up period was 12 months. A total of 44 CBTs were treated in our hospital. The male-to-female ratio was 1:2.4. Only 4.5% of patients had Shamblin I tumors. Patients with Shamblin II and III tumors were 56.8% and 38.6%, respectively. Duplex scan was used to diagnose CBT in all of the patients. The majority of our patients (97.7%) did not receive any preoperative embolization despite an average tumor size of 4.9 cm. Cranial nerve injuries were observed in 29.5% of cases. Meanwhile, stroke was reported in only two cases (4.5%). No deaths were encountered. Surgery is the definitive treatment for CBT. Size and local extension appear to be the main reasons for adverse events rather than surgical techniques. Our results are consistent with those of previously published studies. Good outcomes are expected in high-volume centers with appropriate preoperative imaging.

BACKGROUND: There are limited data regarding potential triggering factors of pulmonary embolism (PE) in coronavirus disease 2019 (COVID-19) patients and its outcomes in comparison with non-infected PE patients. We aimed to identify the contribution of COVID-19 among patients diagnosed with PE and compare risk factors, laboratory results, and outcomes between COVID-19 PE patients and non-COVID-19 PE patients. METHODS: This was a retrospective study of all PE patients between March 2020 and December 2020. The patients were segmented into two groups based on a COVID-19 nasopharyngeal swab result. Statistical analysis was used to determine the differences in risk factors, laboratory values, and outcomes. RESULTS: A total of 58 patients were included. Females comprised 44.8% of the total sample. Overall, 16 patients (27.6%) were COVID-19 positive. Being non-Saudi was observed more in PE COVID-19 patients compared with non-COVID-19 patients (43.7% vs 4.8%, P = 0.001). Intensive care unit (ICU) admission occurred in 50% of COVID-19 PE patients. CONCLUSION: COVID-19 was associated with 27.6% of the PEs in our hospital. Being male or a foreign resident was observed to be associated with COVID-19 PE. Further studies with larger sample sizes are needed, but these results may help the medical community regarding the increased risk of PE among COVID-19 patients and provide evidence of some potentially predictive factors that can be used to identify COVID-19 in high-risk patients.
RESUMEN
Acquired carotid-jugular fistula usually occurs due to neck stab wounds, gunshots, or central vein catheterization. Blunt trauma is a rare cause. These cases usually present with pulsatile swelling, tinnitus, and continued thrills in the neck. Both surgical and endovascular options have been used to manage these fistulas. Coil embolization is also applied in high-flow fistulas. We present a case of a 38-year-old woman free of any pre-existing medical conditions, presenting with a fistula between the external carotid artery and external jugular vein distally and with a high flow. She was treated with fistula embolization using coils while limiting the high flow via a balloon in the jugular vein. Our case highlights the possibility of using coils in high-flow fistulas in anatomically challenging fistulas. Furthermore, relevant literature review is presented to recapitulate unique features and effective management of carotid-jugular fistulas.

OBJECTIVES: To outline our experience with both arterial vascular thoracic outlet syndrome (ATOS) and venous TOS (VTOS). METHODS: This was a retrospective review carried out at King Saud University Medical City, Riyadh, Saudi Arabia, from 1992-2022. All patients were diagnosed based on clinical presentation, imaging, and underwent surgical decompression solely via the supraclavicular approach. The median follow-up period was 18 months (range: 4-36 months). RESULTS: A total of 90 limbs were diagnosed with vascular TOS in 69 patients. Females accounted for 69.6% of the patients and approximately 86.7% had ATOS. All patients were symptomatic and underwent plain thoracic inlet and cervical spine radiography, along with duplex scans in both rest and provocative positions. Total cervical rib resection was carried out in 60% of cases, while 2% had partial resection. First rib resection was carried out in 13.3% of cases and combined cervical and first rib resections were carried out in 23.3%. Vascular procedures were needed for arterial repair in 20% of cases, while venous repair were carried out in 2.2%. No recurrence or post-operative mortality had been reported. Post-operative complications were observed in 18.9% of cases. CONCLUSION: Careful patient selection and diagnosis using advanced, but less invasive radiological imaging coupled with adequate surgical treatment can improve the patient's outcome.

BACKGROUND Coronavirus disease 2019 (COVID-19) has a tremendous impact on the respiratory tract. In severe COVID-19 infections, patients may experience shock and multiple organ failure. We described 4 cases of severe arterial thrombosis induced by COVID-19 with and without other stressors and their responses to treatment measures. CASE REPORT In Case 1, a 61-year-old man was hospitalized for COVID-19 pneumonia 2 weeks prior to the presentation of acute upper-limb ischemia after intravenous forearm line insertion. He was classified as IIB and thus underwent emergency thrombectomy followed by 3 months of enoxaparin. Case 2 was a 41-year-old female patient with granulomatosis who was admitted to the Intensive Care Unit due to COVID-19 pneumonia and developed acute upper-limb ischemia. A medical approach using therapeutic heparin was used. Case 3 was a 65-year-old man who was admitted due to COVID-19-related pneumonia and was otherwise medically and surgically free. We assessed and managed a new onset of the lower-limb IIB acute limb ischemia (ALI). Case 4 was a patient with the first COVID-19 presentation of ALI, which was managed accordingly. CONCLUSIONS The development of a thrombotic event in patients with COVID-19 was previously reported. Moreover, different management options and outcomes have been reported in the literature. Therefore, careful planning is needed for procedures such as cannulation or central line insertion to prevent such events. In addition, short-term anticoagulation therapy might be of clinical benefit when planning a procedure or if the patient exhibits minor arterial complications.

Background and Objectives: Diabetic foot (DF) disease is one of the myriad complications of diabetes. Positive outcomes are expected through a multidisciplinary approach as provided by primary care providers (PCPs). This study aimed to assess the knowledge of DF and attitude of physicians in primary healthcare settings toward DF diagnosis and prevention in Saudi Arabia. Materials and Methods: This observational cross-sectional study used a self-administered questionnaire that was completed by family medicine consultants, residents, and general practitioners working in primary care settings in Riyadh. Results: Of the 152 physicians who completed the survey, (43.4%) completed more than 10 h of diabetes continuing medical education (CME) over the past three years. Most (96.1%) PCPs educate patients about foot self-inspection, and only (64.5%) perform foot inspection at every visit in high-risk diabetic foot patients. PCP knowledge about diagnosing and managing diabetic foot infection was suboptimal. Only 53.9% of participants reported performing a probe-to-bone in DF patients with open wounds. Conclusions: We identified knowledge and action gaps among PCPs. Physicians had acceptable knowledge about preventive measures. However, deficits were found regarding diagnosing and management of DF infections. We recommend addressing these knowledge gaps by incorporating DF lectures and workshops within family medicine conferences and residency programs.

INTRODUCTION: Patients with peripheral artery disease (PAD) are often underdiagnosed and undertreated. This study aimed to assess the knowledge of the recommended target levels of blood pressure, low-density lipoprotein cholesterol, glycosylated hemoglobin A1C, and knowledge and attitude about PAD risk reduction therapies among physicians working in primary care settings in Saudi Arabia. METHODS: This observational cross-sectional study included family medicine consultants, residents, and general practitioners working in a health cluster in the capital city of Saudi Arabia using a self-administered questionnaire. RESULTS: Of the 129 physicians who completed the survey, 55% had completed PAD-related continuing medical education hours within the past 2 years. Despite this, the knowledge score of the recommended target levels was high in only 13.2% of the participants. Antiplatelet therapy was prescribed by 68.2% of the participants. CONCLUSION: Here we identified the knowledge and action gaps among primary care providers in Saudi Arabia. Physicians had an excellent attitude about screening for and counseling about risk factors. However, they showed less interference in reducing these risk factors. We recommend addressing these knowledge gaps early in medical school and residency programs.

BACKGROUND: General practitioners (GPs) and family medicine physicians (FMPs) have a vital role to play in co-ordinating the care for mental disorders. The objective of this study was to determine the perception of GPs and FMPs on the use of cognitive-behavioral therapy (CBT) for depression in Saudi Arabia, and the barriers against the implementation of CBT in such settings. MATERIALS AND METHODS: All physicians working in Primary Healthcare Centers and Family Medicine Clinics in Saudi Arabia were targeted and invited to participate in this cross-sectional study. A self-administered online questionnaire was sent via E-mail through the Saudi Commission for Health Specialties and the Saudi Society of Family and Community Medicine. Data was collected using an existing validated questionnaire and was modified to fit the objectives of current study. RESULTS: A total of 469 FMPs and GPs completed the survey; the mean age of respondents was 38 years. More than half of the FMPs' and GPs' (53%) showed a positive perception of the use of CBT in primary healthcare settings. Most participants (91.9%) were willing to use CBT if they had adequate education and training. More than half of the participants (59.5%) thought it was time-consuming, while 39% thought that CBT training was a very time-intensive process. CONCLUSION: We conclude that more than half of the physicians clearly had a good perception of the effectiveness of CBT administration in primary healthcare settings. Younger physicians were more perceptive. The most agreed-on barrier to CBT implementation was the lack of training and education.
RESUMEN
ABSTRACT: The coronavirus disease of 2019 (COVID-19) pandemic significantly affected different life aspects, including healthcare communities and academic institutes. We aimed to assess the level of stress and risk factors among medical students and interns during the COVID-19 pandemic in the setting of the middle east respiratory syndrome -CoV endemic area.A questionnaire-based cross-sectional study was conducted on a randomly selected sample of medical students and interns. The questionnaire was anonymously self-administered to indicate perceive hygienic practice change, importance of viral prevention domestic hygiene, perceive adequacy of received information, perceived agreement to facilitators to alleviate covid stress, self-reported stress level, and generalized anxiety disorder score.A total of 322 returned the questionnaire (69.7% response rate). Participants had good knowledge regarding severe acute respiratory syndrome -CoV2 in multiple aspects, with an average score of 13.8 out of 14. Two-thirds (62.4%) of the students experienced mild anxiety, (23.9%) had moderate anxiety, (6.8%) had clinically high anxiety level, and another (6.8%) had a clinically very high anxiety level. The stress level, as reported by the respondents (on a 1-10 scale), showed a correlation with the Generalized Anxiety Disorder scale. We observed an increased level of social avoidance and hygienic practice facilitated by availability of hand sanitizers. Majority of the students receive information regarding COVID-19 from reliable and official resourcesMost students reported mild to moderate levels of anxiety, and was associated with enhancement of their universal precaution measures. The availability of alcohol-based hand sanitizers and the off-campus study were great relievers. The importance of reliable pandemic resources in educating students during pandemics is emphasized. Furthermore, this study indicate the importance of students' support services to address mental health and students' wellbeing in the era of pandemics.

OBJECTIVES: To determine the prevalence of vasculopathic diabetic foot and the associated factors in a Saudi tertiary center. Methods: This retrospective chart review included adult patients (≥18 years) diagnosed with diabetic foot between May 2015 and July 2019 in King Saud University Medical City, Riyadh, Kingdom of Saudi Arabia. Based on clinical presentation and laboratory results, the patients were categorized into 2 groups namely, "vascular induced diabetic foot group" and "non-vascular induced diabetic foot group". RESULTS: A total of 404 diabetic patients were enrolled in the study. The mean age of the patients was 62.03±12.30 years; 61.9% were males. Most of the diabetic foot cases had a non-vascular etiology (n=327, 80.9%), while 77 cases (19.1%) were due to vasculopathy. Patient in the vascular group had a significantly higher incidence of coronary artery disease (32.5% versus 14.4%; p greater than 0.001), and a higher incidence of peripheral artery disease (PAD) in the unaffected limb (22.1% versus 2.1%; p less than 0.001). Conclusion: Most cases of diabetic foot were due to non-vascular causes. Old age, history of coronary artery disease, or PAD in the unaffected limb were factors that were significantly associated with diabetic foot due to arterial disease.

Lower limb varicose veins are a common vascular disorder producing pain and disability when truncal vein reflux is present. Endovenous laser ablation (EVLA) of the great saphenous vein (GSV) is a safe and effective method for treating this condition. An unintended complication of this procedure is endothermal heat-induced thrombosis (EHIT) of common femoral vein. A retrospective outcomes analysis of patients who underwent EVLA of the GSV at King Khalid University Hospital from June 2006 to November 2018 was conducted to identify the risks factors and incidence of EHIT. Patients were assessed by clinical examination and duplex ultrasound imaging after the EVLA, and patient demographic characteristics and procedural factors predictive of EHIT were determined. Following EVLA, 11,070 duplex ultrasound examinations were performed for 1,230 limbs, and EHIT was detected in 65 (5.3%) limbs in 60 (6.8%) patients. Essentially all EHIT cases were detected in the first week (n = 63; 96.9%) and clot regression occurred over a period of 1-4 weeks. There were no significant differences in patient demographic characteristics or procedural factors between the EHIT and non-EHIT groups, except for the percentage of women (86% v 73%; P = .02), maximum GSV diameter (6.7 ± 2.7 mm v 6.0 ± 2.1 mm; P = .04), and percentage of patients with a competent saphenofemoral junction (41% v 37%; P < .001). EVLA is a safe treatment for great saphenous vein reflux, but EHIT can occur and was associated with female sex, large maximum GSV diameter, and competent saphenofemoral junction. Venous duplex imaging after EVLA is recommended because EHIT is asymptomatic in most patients.

BACKGROUND: This study aims to evaluate the effectiveness of ultrasound-guided thrombin injection versus ultrasound-guided compression repair in the management of iatrogenic femoral artery pseudoaneurysms. METHODS: Between June 2006 and December 2015, a total of 29 consecutive patients (15 males, 14 females; mean age 54 years; range 26 to 81 years) with a femoral pseudoaneurysm treated by ultrasound-guided thrombin injection were retrospectively analyzed. These patients were compared with a historical group of 36 patients (21 males, 15 females; mean age 44 years; range 32 to 65 years) who underwent ultrasound-guided compression repair between February 1999 and May 2006. Medical records and vascular laboratory findings of all patients were reviewed. Successful treatment was defined as complete cessation of flow into the false lumen with preservation of flow in the femoral artery. RESULTS: The ultrasound-guided thrombin injection showed a success rate of 100%, whereas ultrasound-guided compression repair had a success rate of 80.5%, which was possibly affected by anticoagulant therapy, hypertension, and an aneurysm size of >6 cm. However, none of these factors did not affect the success of thrombin injections. CONCLUSION: Ultrasound-guided thrombin injection is a highly successful, easy to perform, accepted, and well-tolerated method by patients. It is more effective compared to compression therapy in patients with hypertension, large aneurysms, and who are on anticoagulant therapy.
RESUMEN
BACKGROUND: Arterial pseudoaneurysms are a well-known complication resulting from procedures requiring arterial wall puncture. Previously, surgical repair was the definitive treatment option for arterial pseudoaneurysms despite being relatively invasive and time-consuming. Ultrasound-guided thrombin injection (UGTI) has become the standard of care since its initial description back in 1997. We aimed to evaluate the safety and efficacy of UGTI for the treatment of arterial pseudoaneurysms at the King Khalid University Hospital Vascular Lab. METHODS: A retrospective analysis of prospectively maintained data was conducted on all patients diagnosed with arterial pseudoaneurysms by Doppler ultrasound between 2006 and 2019. Patients with large arterial pseudoaneurysms (>1.5 cm) qualified for thrombin injections. Individuals with a known hypersensitive to thrombin were excluded. All included patients were treated with UGTI until resolution and were followed at postoperative days 7 and 30. RESULTS: In all, 35 patients qualified for thrombin injections. The mean age of the included patient population was 56.5 (range, 24-81) years. The majority of them were hypertensive (N.=26, 74.3%), and a quarter of them were on anticoagulant treatment (N.=9, 25%). The mean thrombin injection dose was 1000 U (range, 500-1500 U). In 34 of 35 (97.1%) patients, a thrombin injection resulted in complete thrombosis of the pseudoaneurysm lumen within a few seconds. There were no complications or recurrence of pseudoaneurysm after UGTI during the follow-up period. CONCLUSIONS: Throughout the study period of 14 years, we did not encounter any procedural complications or arterial pseudoaneurysm recurrence. This is attributed to a safe procedural technique and proper patient selection. UGTI for arterial pseudoaneurysms is a safe, successful, and convenient treatment for both patients and surgeons.
