Background Endovascular stent grafting has emerged as an option to treat traumatic aorta injuries with reported significantly low mortality and morbidity. Stent collapse is one of the complications that can occur in this type of treatment. The aim of this article is to analyze the expected cause of stent collapse and to draw attention to the importance of the surveillance follow-up, as this phenomenon may occur late postdeployment. Methods A retrospectively collected dataset from the two highest volume trauma centers in Saudi Arabia was analyzed between April 2007 and October 2012. A total of 66 patients received stent grafts for traumatic aortic injury and were included in the study. We apply Ishimaru's anatomical aortic arch zones and Benjamin's aortic injury grading systems. There were 35 patients with aortic injury at zone 2, 26 patients in zone 3, and 5 patients in zone 4. About 96% (63) of the injuries were grades 2 and 3, including large intimal flap or aortic wall pseudoaneurysm with change in wall contour. The technical success rate, as defined by complete exclusion of lesions without leaks, stroke, arm ischemia or stent-related complications, was 90%. Results Proximal stent collapse occurred in 4.5% of patients (3 of 66 inserted stents) during follow-up of 4 to 8 years (mean, 6 years). Patients with stent collapse tended to have an acute aortic arch angle with long-intraluminal stent lip, when compared with patients with noncollapsed stents. Intraluminal lip protrusion more than 10-mm increased collapse (p < 0.001). Stent-grafts sizes larger than 28 mm also demonstrated a higher collapse rate (p < 0.001). Conclusions The risk of stent collapse appears related to poor apposition of the stent due to severe aortic arch angulation in young patients and to large stent sizes (>28 mm). Such age groups may have more anatomical and aortic size changes during the growth. Clinical and radiological surveillance is essential in follow-up after stent-graft treatment for traumatic aortic injury.
The study aims to summarize the updated evidence regards, epidemiology, causes, clinical manifestations, and management of paralytic ileus. Lower abdominal surgical procedure, particularly big open cuts and increased bowel operations, is linked with an increased hazard of bowel obstruction. Though, numerous risk issues have been revealed to upsurge the probability and resistance of intestinal obstruction, such as prolonged abdominal / pelvic surgery, lower gastrointestinal (GI) surgery, open surgery, retroperitoneal spine surgery, opioid use, cancer peritoneal, intra-abdominal inflammation (sepsis / peritonitis), delayed enteral nutrition or nasogastric (NG) tube placement, and hypokalemia. Signs of intestinal obstruction are tachycardia caused by any interruption of movement, absence of abdominal pain, abdominal distention and tenderness, shortness of breath, and hypovolemia. Bowel sounds disappear and flatulence is not discharged, leading to gastric stasis, which can cause hiccups, discomfort, and easy vomiting. Preventive measures include avoiding unnecessary exposure and over-processing of the intestine or traction of the mesentery. Treatment is conservative, as this condition is mostly self-limited. Pharmacologic Therapy have little place, but there are some exceptions of adequate values.
Cervical spondylosis is a term that encompasses a wide range of progressive degenerative changes that affect all components of the cervical spine (i.e., intervertebral discs, facet joints, Luschka joints, flava ligaments, and laminae). It is a natural aging process and occurs in most people after the age of five. Most people with radiographic spondylotic changes in the cervical spine remain asymptomatic, and 25% of those under 40, 50% of those over 40, and 85% of those over 60 show some evidence of degenerative changes , including changes in the environment. Uncovertebral joints, facet joints, posterior longitudinal ligament (PLL) and yellow ligament lead to narrowing of the spinal canal and intervertebral foramina. As a result, the spinal cord, spinal vasculature, and nerve roots can become compressed, leading to the three clinical syndromes that occur with cervical spondylosis: axial neck pain, cervical myelopathy, and cervical radiculopathy. Cervical spondylosis is usually diagnosed for clinical reasons only, but imaging is also required. Treatment for cervical spondylosis can be medical or surgical, depending on whether the patient has symptoms of myelopathy, radicular pain, or neck pain.
