Volume 64, Issue 8 (8-2006)
Abstract
Background: A plan for management of infected arterial pseudoaneurysm has evolved from our experience with forty two cases of such aneurysms treated between 1378 and 1382.
Methods: Clinical data of 42 patients with femoral pseudoaneurysm resulting from addictive drug injection who presented in emergency department of Sina Hospital between 1378 and 1383 were retrospectively reviewed.
Results: All patients were men with the mean age of 36.9 years. Twenty eight patients were referred from other medical centers. The mean time of delay in presentation was 17.3 days. The mean duration of drug injection was 14 months. Primary repair and emergent vascular bypass were performed in 3(7.1%) and 2(4.8%) patients, respectively. 5(11.9%) patients undergone delayed revascularization. Thirty two (76.2%) patients returned to their normal lifestyle without any vascular bypass. One patient required amputation and one patient died due to sepsis and acute renal insufficiency.
Conclusion: Management of infected femoral pseudoaneurysms is simple ligation of the external iliac or femoral artery. When Doppler is not available “Operation Room and postoperative Direct Observation” is recommended in such patients to avoid unnecessary revascularization surgery.

Volume 69, Issue 5 (8-2011)
Abstract

Background: Prevalence of Abdominal Aortic Aneurysm (AAA), estimated by various studies, ranged from 4.1% to 14.2% in men older than 60 years. Most cases of AAA are asymptomatic and often discovered incidentally. Approximately the initial presentation in 12% of cases of AAA is sudden rupture with subsequent high mortality. This study was performed to evaluate the prevalence and screening necessity of AAA among Iranian men older than 65 years old.

Methods: In this cross-sectional study, men older than 65 years, who referred for ultrasound examination to three different centers in Tehran, Iran at the year 2008 were included for evaluation of size of the abdominal aorta and presence of AAA.

Results: A total of 240 men older than 65 years enrolled in this study. AAA was found in 24 of the participants with prevalence rate of 10% in the studied population. Mean diameter of detected aneurysms was 3.931.435 cm. In 4 (1.7%) subjects, aneurysms greater than 5.5 cm in diameter were detected. One of these four subjects had the history of coronary artery disease and one was cigarette smoker. Three out of four had history of hypertension.

Conclusion: Considering the estimated prevalence rate of AAA by the current study and the population of Iranian men older than 65, implementing of mass screening for AAA in this group would detect 986 asymptomatic cases each year. Therefore, the authors recommend further studies about the cost-effectiveness of mass screening for AAA among Iranian men above 65 years.

Abstract

Background: Late postpartum hemorrhage (PPH) is defined as uterine bleeding between 24 hours until 12 weeks after delivery. Uterine artery pseudoaneurysm is a rare cause of life-threatening late postpartum hemorrhage (PPH). Emergency uterine artery embolization (UAE) is an appropriate method for control of hemorrhage. The aim of this report was to present a case of uterine artery embolization in late postpartum hemorrhage due to uterine artery pseudoaneurysm.

Case Presentation: A 25-year-old woman with the history of three previous cesarean sections was admitted 35 days after the last cesarean. She had severe vaginal bleeding for 35 days after cesarean section. Because of severe vaginal bleeding 35 days after cesarean section, the patient was at nearly shock state (BP=90.60 mmHg, positive tilt test, tachycardia PR=120/m). In speculum examination, she had severe vaginal bleeding, but there was no lesion in vagina or cervix, also, bimanual examination of the uterus and adnexal area were normal. She reanimated by two liters of normal saline and uterotonic agents (oxytocin and methergine) were administered.

Laboratory data showed severe anemia (Hb=6.5 gr/dl), but coagulation tests were normal. Ultrasonography didn’t show any abnormality. Because of continuation of vaginal bleeding after stabilization of the patient, UAE was planned. During pelvic angiography, a pseudoaneurysm was diagnosed and then it was treated by successful UAE.

Conclusion: Uterine artery embolization is a conservative management for control of late postpartum hemorrhage. It can be a useful and alternative method for uterine and hypogastric artery ligation and hysterectomy, therefore it has an important role in treatment and fertility preservation for young women.

Volume 77, Issue 9 (12-2019)
Abstract
Background: Cerebral aneurysm disease causes intracranial hemorrhage by rupturing, which can eventually, lead to organ failure or death. For this reason, it is important to anticipate the reasons for rupturing of a cerebral aneurysm from biomechanical point of view. Investigating this disease may even help the physicians to find treatments and predict the patient’s situation. This research was conducted to understand risks of development and rupture of a patient-specific cerebral aneurysm.
Methods: In a computational simulation, fluid-structure interaction method has been used for a patient-specific case. Also, considering the speed of the systole as the initial condition of the problem, the blood fluid domain has been solved in three types of fluid mathematical models (Newtonian, non-Newtonian Carreau, and non-Newtonian power-law). Then, the pressure results on the wall have been transmitted to ANSYS software, version 15.0 (ANSYS Inc., Canonsburg, PA, USA) and the structure has been solved based on three material models (linear elastic, hyperplastic Neo-Hookean and hyperplastic Mooney-Rivlin, with 5 parameters). The study was done in University of Tehran, Iran, from October 2016 to September 2018.
Results: Shear stress, pressure, flow velocity, wall displacement and von-Mises stress have been extracted from the simulations. The average wall displacement of the aneurysm was 1.8 mm. Also, no significant difference was found in the amount of arterial wall displacement, with constant wall material model and different blood models. However, a significant difference has been observed in the case of considering constant blood model and different wall material models in the value of displacement.
Conclusion: With regard to the amount of displacement of the aneurysm wall in this particular patient, with the geometry and location of the specific aneurysm, the brain nerves 3 and 6 were under stress and exposed to damage. The minimum shear stress was in the aneurysm neck, which stimulates the endothelial cells in the area of aneurysm. In addition, the blood model didn’t had a significant effect on the displacement calculations, while the wall material model played a more decisive role.

Zohreh Shalchi, Katayoun Borhani, Hamid Eshaghi, Mahmoud Khodabandeh,
Volume 79, Issue 2 (5-2021)
Abstract
Background: Purulent cervical lymphadenitis presents with different manifestations such as fever and Erythema of the skin at the site of infection. The appropriate treatment for purulent lymphadenitis are antibiotics. If there is no response to antibiotic treatment, other causes should be considered, including uncommon infectious causes (for example Mycobacterium infections or fungal infections), malignancy and Kawasaki diseases, etc. This study aimed to introduce a child with suspected purulent cervical lymphadenitis, who was initially presented with purulent lymphadenitis and was treated with broad-spectrum antibiotics. Due to the lack of response to treatment, further laboratory and clinical examinations were performed for him, then he was diagnosed with Kawasaki disease.
Case Presentation: A 10-year-old boy with fever and severe cervical lymphadenitis was referred to Tehran Children's Medical Center Hospital in May 2018. He had leukocytosis in his lab test and the acute reactant phase was high. He was diagnosed with purulent lymphadenitis and he was treated with broad-spectrum antibiotics. But no therapeutic response was observed, the patient's fever continued and erythrocyte sedimentation rate (ESR) increased in the laboratory tests. The patient's knee developed arthralgia, and Inflammation of the neck spread to the chest wall. Therefore echocardiography was performed. The patient's left anterior descending artery (LAD) had ectasia in echocardiography (LAD>2/5 SD). The patient was diagnosed with atypical Kawasaki disease, therefore the appropriate treatment was started for him and a dramatic clinical response was seen. His fever stopped and the patient's cervical lymphadenitis had completely improved. In the follow-up, the patient's left anterior descending artery (LAD) ectasia was resolved.
Conclusion: Kawasaki disease is one of the causes of cervical lymphadenitis in children. If a patient with suspected purulent lymphadenitis is treated with appropriate antibiotics but no adequate response is seen, Kawasaki disease should be considered and the patient must be re-evaluated for Kawasaki disease.

Volume 81, Issue 6 (9-2023)
Abstract
Background: Splenic artery aneurysm is seen in less than 0.1% of the population. Aneurysm of the splenic artery is more common in pregnant women. One of the life-threatening complications of splenic artery aneurysm is the spontaneous rupture of the aneurysm, which causes hemorrhagic shock. This complication is more common in pregnant women than other people in the society and has more mortality and morbidity. In this study, a pregnant patient with spontaneous rupture of splenic artery aneurysm is reported.
Case Presentation: The patient is an 18-year-old woman, 20 weeks pregnant, who came to the Emergency department of Bentolhoda Hospital in Bojnurd with diffuse  sudden onset of abdominal pain in the September of 2023. On examination, the patient's vital signs were unstable, which was due to the presence of hemorrhagic shock. In the examination of the patient's abdomen, or generalized tenderness and rebound tenderness? was evident, suggesting peritonitis. According to the ultrasound report, abundant free fluid and fluid containing blood was drained from the abdomen under ultrasound guidance. The patient underwent surgery with the diagnosis of hemorrhagic shock with a midline incision of the abdomen above and below the umbilicus. In the performed surgery, evidence of splenic artery aneurysm rupture was evident. For the patient, ligature and resection of splenic vessels (artery and vein) and splenectomy were performed. After surgery and stabilization of the patient's condition, fetal health ultrasound was performed, and the fetus had no heartbeat. Therefore, medical induction of abortion was performed, and after 48 hours, the fetus was completely expelled, and then mother was transferred to the ward. And four days after the surgery, she was discharged with general improvement. No remarkable adverse effects were observed after surgery.
Conclusion: One of the rare diseases is splenic artery aneurysm, which is difficult to diagnose due to its asymptomatic rupture and high mortality rate.
