Treatment Outcome of Traumatic Subclavian Artery Injuries.

BACKGROUND: Traumatic subclavian artery injuries are associated with high morbidity and mortality. Thoracic cage and clavicle provide a well protection of the underlying subclavian vessels and nerves and also cause a very limited operation space during open surgery. The endovascular modality is less invasive and alternative to conventional open surgical reconstruction. PURPOSE: The purpose of this study was to analyze the different therapeutic effects on limb salvage. METHODS: A retrospective review of patients who presented with blunt or penetrating injuries to the subclavian arteries between March 2012 and March 2021. RESULTS: Endovascular and open repairs were both effective for traumatic subclavian artery injury. There was no statistical difference in the limb salvage, mortality, procedure-related complication, reintervention rate and in-hospital medical complications. Intraoperative blood loss, red blood cell transfusion requirement and length of hospital stay were significantly lower in the endovascular intervention group. CONCLUSION: Endovascular treatment represents an attractive alternative to the traditional surgical approach for the treatment of traumatic injuries in the subclavian.

What are the strongest indicators of intracerebral hemorrhage in mild traumatic brain injury?

BACKGROUND: Although there are eight factors known to indicate a high risk of intracranial hemorrhage (ICH) in mild traumatic brain injury (TBI), identification of the strongest of these factors may optimize the utility of brain CT in clinical practice. This study aimed to evaluate the predictors of ICH based on baseline characteristics/mode of injury, indications for brain CT, and a combination of both to determine the strongest indicator. METHODS: This was a descriptive, retrospective, analytical study. The inclusion criteria were diagnosis of mild TBI, high risk of ICH, and having undergone a CT scan of the brain. The outcome of the study was any type of ICH. Stepwise logistic regression analysis was used to find the strongest predictors according to three models: (1) injury pattern and baseline characteristics, (2) indications for CT scan of the brain, and (3) a combination of models 1 and 2. RESULTS: There were 100 patients determined to be at risk of ICH based on indications for CT of the brain in patients with acute head injury. Of these, 24 (24.00%) had ICH. Model 1 found that injury due to motor vehicle crash was a significant predictor of ICH, with an adjusted OR (95% CI) of 11.53 (3.05 to 43.58). Models 2 and 3 showed Glasgow Coma Scale (GCS) score of 13 to 14 after 2 hours of observation and open skull or base of skull fracture to be independent predictors, with adjusted OR (95% CI) of 11.77 (1.32 to 104.96) and 5.88 (1.08 to 31.99) according to model 2. DISCUSSION: Open skull or base of skull fracture and GCS score of 13 to 14 after 2 hours of observation were the two strongest predictors of ICH in mild TBI. LEVEL OF EVIDENCE: III.

A Life Saving Emergency Department Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) with Open Groin Technique.

A 53-year-old male pedestrian was hit by a car and arrived at our hospital with a blunt abdominal injury and hemorrhagic shock. Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) was performed in a timely fashion using the open groin technique in the emergency room. The procedure resulted in rapid improvement of hemodynamic status while the bleeding source was controlled. Recently, REBOA is a proper adjunctive procedure in major non-compressible torso hemorrhage patients. The procedure requires a portable X-ray or fluoroscopic machine in the ER to confirm the balloon's position. This method has likely limited the use of REBOA in developing countries. The procedure with open groin technique, using anatomical landmarks and physiologic change to confirm the position of the balloon, has been developed to address these concerns. Here we report on the treatment's success with this technique and believe that it can benefit trauma patient care.

Sandwich EVAR occludes Celiac and Superior Mesenteric Artery for Infected Suprarenal Abdominal Aortic Aneurysm Treatment.

Introduction. Infected aortoiliac aneurysms are rare, representing only 1% to 2% of all aortic aneurysms; we present a case of infected suprarenal aortic aneurysm with a nearly occluded celiac artery and superior mesenteric artery treated using an endovascular technique to preserve collateral in the retroperitoneal space from the inferior mesenteric artery for supplying visceral organs.

Prognostic Factors for Large Symptomatic Gists: a Pragmatic Study of Experiences From a University Hospital Over 10 Years

Background: Gastrointestinal stromal tumors (GISTs), which are mesenchymal neoplasms in the gastrointestinal (GI) tract account for 0.2% of all GI tumors. Several factors have been reported (mostly from studies conducted in Western countries) to be associated with survival in GISTs cases such as tumor site, staging, and tumor size. We conducted a pragmatic study, looking at a 10-year period, aimed at understanding the prognostic factors related to GISTs in a university hospital. The study population consisted of patients with large symptomatic GISTs. Methods: This was a retrospective study conducted at the Department of Surgery in the Khon Kaen University Hospital (Thailand). All patients diagnosed with GISTs that were treated between 2006 and 2015 were consecutively enrolled. The diagnosis of GISTs was made by examining the pathological section and immunohistochemistry results. The outcome of this study was the rate of survival after surgical treatment. Prognostic factors were determined using Cox regression analysis. Results: There were 124 GISTs patients treated at the university hospital during the 10-year period of the study. The median age of all patients was 54 years (range 24-83 years). Of those, 119 (95.9%) were symptomatic. Rectosigmoid GISTs accounted for 20.2% of all tumors. The median tumor size was 8 cm. A total of 68 patients (54.8%) died. The median survival time for all patients was 7.18 years (1st -3rd quartile range 6.48-7.89). There were three significant factors associated with death including male gender, liver metastasis, and peritoneal metastasis. Conclusion: Male gender, liver metastasis, and peritoneal metastasis were prognostic factors for large symptomatic GISTs.

Patency of vascular accesses for Thai hemodialysis patients.

OBJECTIVE: Vascular access for hemodialysis is the mode of renal replacement therapy for chronic renal failure patients. The present study reports patency rates of arteriovenous fistula (AVF) and graft (AVG). MATERIAL AND METHOD: Between July 2008 and June 2011, 336 vascular accesses were performed in 293 patients in Department of Surgery, Faculty of Medicine, Khon Kaen University. The patient was follow until June 2012. A retrospective review was conduct to analyze patency rate. RESULTS: Two hundred ninety three patients underwent 286 AVFs and 50 AVGs. Patency rate was analyzed with the Kaplan-Meier method. Primary patency rate of AVF at one, two, and three-year was 78.69%, 70.43%, and 60.72%, respectively Assisted primary patency of AVF at one, two, and three-year was 88.24%, 75.63%, and 40.34%, respectively. Secondary patency rate of AVF at one and two-year was 71.46% and 71.46%, respectively. Primary patency rate of AVG at one, two, and three-year was 63.94%, 43.93%, and 36.60%, respectively. Assisted primary patency of AVG at one-year was 100%. Secondary patency rate of AVG at one-year was 46.30%. Graft infection was the major complication ofAVG (12%). CONCLUSION: The authors' results of vascular access surgery were comparable to results from a review of literature.
