Materials and Methods: All women who underwent UAE for obstetric-related hemorrhage during a 52-month period culminating in April 2009 were included. Clinical success was defined as obviation of hysterectomy. Blood product requirements before and after UAE were calculated. Statistically significant associations between subject characteristics and clinical success were evaluated. The two subgroups of women with uterine artery pseudoaneurysms and women who underwent cesarean section were examined separately as well. Results: Sixty-six women (mean age, 33 years; range, 17-47 y) underwent UAE, with an overall clinical success rate of 95% (98% for primary PPH, 88% for secondary PPH, and 94% for PPH associated with cesarean section) and an overall complication rate of 4.5%. Mean pre-and postembolization transfusion requirements were 3.1 U and 0.4 U of packed red blood cells, respectively. The only significant characteristic identified for the cases that necessitated hysterectomy was an increased transfusion requirement after UAE (increase of 1.0 U Ϯ 0.5; P ϭ .02). Uterine artery pseudoaneurysms were associated with secondary PPH (P ϭ .01) and cesarean section (P ϭ .03). Conclusions: The threshold for UAE in women with PPH should be low, as it is associated with a high clinical effectiveness rate and a low complication rate. Uterine artery pseudoaneurysms should be suspected in women presenting with secondary PPH after cesarean section. ABBREVIATIONS PPH ϭ postpartum hemorrhage, PRBCs ϭ packed red blood cells, UAE ϭ uterine artery embolization Despite advances in medical, surgical, and endovascular therapy, which have decreased the maternal mortality rate by 99% during the past century in the United States (1), obstetric hemorrhage continues to be a leading cause of maternal morbidity and mortality. The incidence of obstetric hemorrhage varies depending on the definition used. Postpartum hemorrhage (PPH), defined as blood loss exceeding 500 mL, is a common entity that complicates as many as 18% of all deliveries (2,3). More severe obstetric hemorrhage, defined as blood loss in excess of 1,000 mL, may occur in 1%-5% of all deliveries (4). Obstetric hemorrhage continues to be the single most important cause of maternal mortality worldwide, accounting for 25%-30% of all maternal deaths, and it represents the most common maternal morbidity in the developed world (2,5,6). Since its introduction as a treatment for PPH in 1979 (7,8), UAE has been shown to be associated with high technical success rates and good clinical outcomes for the treatment of primary and secondary PPH (9-12). However, optimal patient selection and the appropriate position of UAE in the treatment decision tree for PPH remain to be elucidated. Current studies in the literature lack standardization in patient selection as well as embolization techniques, and there is a lack of randomized controlled trials comparing pharmacologic, surgical, and endovascular interventions (9,13). Moreover, it appears that, despite encouraging results in the literature and its potential role in

Adenocarcinoma is even rarer accounting for 9% of primary vaginal carcinomas. (1, 2, 4) Presentation with secondary involvement including metastatic disease or direct extension of extravaginal tumours being far more frequent. (3) Historically these cancers are more common in elderly and postmenopausal women. (2) Human papillomavirus, particularly subtypes 16 and 18, has been implicated as a causative agent of malignancy, increasing incidence in the younger population. (3) Vaginal cancer is most frequently diagnosed with physical examination and pelvic biopsy. It usually results in painless vaginal bleeding and discharge. MR imaging (MRI) is the modality of choice for initial local staging and follow up of vaginal cancer. Due to its superlative soft tissue contrast and high-resolution multiplanar imaging. Case report A 57-year-old postmenopausal female patient, multipare, presented with abnormal vaginal bleeding of two years duration. This was complicated by dysuria just four months prior to presentation.

It is a predisposing factor of recurrent pancreatitis. In this case report, we describe a case of a 24-year-old male suffering from an ansa pancreatica with a non-patent major papilla, diagnosed on magnetic resonance cholangiopancreatography (MRCP).The ansa pancreatica was revealed by an episode of acute pancreatitis attacks in chronic pancreatitis. Endoscopic retrograde cholangiopancreatography (ERCP) confirmed important abrupt dilation in the main pancreatic duct with an ansa loop in the pancreatic duct in the head of the pancreas, and a sphincterotomy of the minor papilla was performed. The procedure was difficult and the placement of a long-term pancreatic stent during the ERCP was impossible, thus a surgical pancreatico-jejunostomy was proposed as a treatment of an ansa pancreatica with a non-patent major papilla.

The main mechanism is a direct invasion of the bladder by the tumor. Intraluminal bladder metastases from distant primary tumors remain exceptional. Patient: We report the case of a 56-year-old patient without any particular medical history initially admitted for an occlusion caused by a transverse colic tumor. The patient did not have clinically haematuria and the initial scan did not show a location or abnormality in the bladder. Initial surgical exploration did not find peritoneal or bladder abnormalities. The patient's evolution will be marked by the appearance of bladder thickening at a distance from the primary tumor and peritoneal carcinosis. The immunohistochemical study in addition to the anatomopathological examination resulted in positive marking of the chorion tubes by anti CDX2 and anti CK 20 and positive marking of s...

Ovarian vein thrombosis (OVT) is a very serious and rare disease. In this study, we report tow rare case of women with coronavirus who were hospitalized with a right ovarian vein thrombosis mimicking acute abdomen who progressed well on anticoagulation. Our report adds further document in Side effects and rare localisation of obstruction of veins and arteries in patient with corona virus. Keywords Coronavirus disease • Ovarian vein thrombosis • Acute abdomen Highlights • In the first case, our patient was diagnosed with an idiopathic OVT because no risk factors for OVT were found, the patient's abdominal pain subsided few days after starting anticoagulation. • In the second case, the patient had no risk factors for OVT other than childbirth, It is noteworthy that we did not see any evidence of venous thrombosis in previous deliveries before COVID-19 and the biological assessment for thrombophilia or autoimmune disease was negative, consequently, it is thought that such acute thrombosis taked place during COVID-19 disease.
