An extensive suprarenal inferior vena cava thrombosis successfully treated with catheter-directed thrombolysis in a postpartum 14-year-old girl.

We report a case of extensive early postpartum acute suprarenal inferior vena cava thrombosis in a 14-year-old girl. Management included catheter-directed-thrombolysis, aiming to save renal function and prevent fatal pulmonary embolism. Treatment decisions were mostly based on adult guidelines, as guidelines for the paediatric population are not yet available.

New Insights into Cervicofacial Vascular Anomalies.

Congenital cervicofacial vascular anomalies are extremely rare and present many difficulties in diagnosis and treatment requiring a multidisciplinary approach. Firstly, there is little consensus on this subject among head and neck specialists. There are two main types of vascular anomalies: vascular tumors and vascular malformations. Vascular malformations are also divided into malformations with slow blood flow (veins, lymphatics, capillaries or combined) and malformations with a fast blood flow (arteriovenous malformations and fistula). Vascular tumors like hemangiomas are known for their spontaneous involution with aging, while vascular malformations grow in dimensions with age. It is very important to choose the correct differential diagnosis between cervicofacial hemangiomas and vascular malformations for proper therapy management. Anamnesis and clinical exams help in raising suspicions about the real nature of a cervico-vascular anomaly. Furthermore, imaging brings in-depth details of the anomaly, ranging from ultrasound and contrast CT to MRI scanning and minimally invasive angiography. Angiography with selective embolization is rarely a curative procedure for arteriovenous malformations, being more suitable as a preliminary step before attempted surgical removal. Surgery is clearly necessary when there are aesthetic and functional deficits. Slow-flow vascular malformations present a reduced morbidity, and in cases without involution, the surgical ablation is reserved for the cases with aesthetic dysfunctions or psychological trauma. Lymphatic malformations must undergo surgical ablation when they are associated with mass effects and compression of great vessels or aerial viscera. The prognosis after surgical removal is good, with a low rate of recurrence or morbidity. Fast-flow vascular malformations require a combined approach, with embolization and excision in the next 48 h for safety reasons. Removal may be followed by reconstructive surgery depending on the location and dimensions of the malformation, with a possible secondary recovery of the normal microscopic vessels. Some of the masses may hinder the normal airflow and swallowing. Pathology is the gold standard for confirming the clinical and imaging diagnosis.

Our Experience in Using the Endovascular Therapy in the Management of Hemorrhages in Obstetrics and Gynecology.

(1) Background: A quarter of maternal deaths are caused by post-partum hemorrhage; hence obstetric bleeding is a significant cause of morbidity and mortality among women. Pelvic artery embolization (PAE) represents a minimally invasive interventional procedure which plays an important role in conservative management of significant bleeding in Obstetrics and Gynecology. The aim of this study was to evaluate the effect and the complications of PAE in patients with significant vaginal bleeding with different obstetrical and gynecological pathologies. (2) Methods: We conducted an observational, retrospective study on 1135 patients who presented to the University Emergency Hospital of Bucharest with vaginal bleeding of various etiology treated with endovascular therapy. All the patients included in the study presented vaginal hemorrhage that was caused by: uterine leiomyomas, genital tract malignancies, ectopic pregnancy, arterio-venous mal-formations and other obstetrical causes. We excluded patients with uncontrolled high blood pressure, severe hepatic impairment, congestive heart failure, renal failure or ventricular arrhythmias. (3) Results: Bleeding was caused in 88.19% of cases by uterine leiomyomas (n = 1001), 7.84% (n = 89) by cervical cancer, 2.29% by ectopic pregnancy (n = 26), 1.23% by arteriovenous malformation (n = 14) and 0.52% by major hemorrhage of obstetrical causes. Endovascular procedures were used in all the cases. In patients with uterine leiomyomas, supra-selective uterine arteries embolization was used. In 97% (n = 1101) of patients, bleeding was stopped after the first attempt of PAE. 3% (n = 34) needed a second embolization. In 12 of 14 cases of AVM, PAE was successful, two other cases needed reintervention; (4) Conclusions: Endovascular procedures represent a major therapy method for both acute and chronic hemorrhage in Obstetrics and Gynecology. It can be used in post-partum or post-traumatic causes of vaginal bleeding, but also in patients with chronic hemorrhage from uterine leiomyomas or inoperable genital malignancies or even as a preoperative adjuvant in cases of voluminous uterine fibroids or invasive malignant tumors, aiming to reduce intraoperative hemorrhage.

Uterine Artery Embolization Combined with Subsequent Suction Evacuation as Low-Risk Treatment for Cesarean Scar Pregnancy.

OBJECTIVE: The aim of this study is to propose a standardized management of care for patients diagnosed with cesarean scar pregnancy (CSP). There are two types of CSP: Type 1 (on the scar) vs. type 2 (in the niche). To date there is no international standard to predict the extent of invasion or the optimal management of CSP. MATERIALS AND METHODS: We used intramuscular methotrexate injection followed by uterine artery embolization combined with suction evacuation as a conservative approach for the treatment of seven patients diagnosed with CSP. Our inclusion criteria, to be satisfied simultaneously, were established as follows: (1) patients with CSP; (2) early gestational age ≤ 9 weeks, and (3) written consent of the proposed treatment of the patient. RESULTS: This course of treatment produced a positive outcome in all cases. We did not have any complications (e.g., emergency hysterectomy, perforation of the uterine cavity, severe hemorrhage, or endometritis) during the procedures or in the follow-up. The most important predictors of successful management are early diagnosis of CSP and orientation of the invasive trophoblast opposite to the scar. CONCLUSIONS: The main finding from this series of cases is that associating systemic methotrexate and uterine artery embolization provides efficient and low-risk management of CSP. This treatment regime is adequate for both types of CSPs. We consider that early localization diagnosis of pregnancy following a cesarean delivery is mandatory for CSP morbidity prevention.

Stress cardiomyopathy misinterpreted as ST-segment elevation myocardial infarction in a patient with aneurysmal subarachnoid hemorrhage: a case report.

Cardiac abnormalities are frequently reported in acute subarachnoid hemorrhage (SAH) patients. However, frank ST-elevation and myocardial dysfunction mimicking acute coronary syndrome is a rare occurrence. Systemic and local catecholamine release mediate myocardial injury and may explain raised troponin levels, concordant regional wall motion abnormalities and systolic dysfunction. These findings can pose a significant problem in the acute setting where "time-is-muscle" paradigm can rush clinicians towards a "rule-in" diagnosis of acute myocardial infarction. We present the case of a 60-year-old male who arrived at a regional emergency department with loss of consciousness, chest pain and headache. His ECG showed ST-elevation in precordial leads with corresponding region wall motion abnormalities and dynamically elevated troponin levels which supported a diagnosis of acute myocardial infarction. Percutaneous coronary intervention was attempted but found no hemodynamically significant lesions and the patient was managed conservatively with antithrombotic treatment. Further work-up for his headache led to the diagnosis of aneurysmal SAH and subsequent endovascular coiling. The patient was discharged with a good clinical outcome. We discuss the potential catastrophic consequences of interpreting neurologic myocardial stunning as STEMI. Use of potent antithrombotic therapies, like bridging thrombolysis, in this setting can lead to dismal consequences. Clinical history should still be carefully obtained in the acute setting in this era of sensitive biomarkers.

Failed Attempt of Total Hip Arthroplasty in a Patient with Klippel-Trenaunay Syndrome: A Case Report.

CASE: A 41-year-old man with Klippel-Trenaunay syndrome presented with pain and limited range of motion in his left hip due to secondary hip osteoarthritis. After preoperative assessment, which also included tomography and conventional arteriography, total hip arthroplasty by direct anterior approach was attempted, but rapid blood loss occurred during surgery and the procedure had to be stopped. CONCLUSIONS: Total hip arthroplasty should be undertaken with great caution in a patient with Klippel-Trenaunay syndrome. Preoperative conventional arteriography alone may not reveal the true extent of vascular malformations, which may lead to catastrophic results.

Cystic lymphangioma of nasopharynx in a 54-year-old man - case report. A new histogenetic hypothesis.

Lymphangiomas are enough rare benign congenital tumors of the lymphatic vessels, frequently encountered during childhood. They are found in the head and neck region, the isolated localization in the nasopharynx is very rare. We present the case of 54-year-old man admitted in the Department of Ear, Nose and Throat (ENT), Emergency University Hospital of Bucharest, Romania, with a nasopharynx tumor certificated by computed tomography (CT) scan with significant bleeding to a previous incisional biopsy temptation rising angiofibroma suspicion. We performed the radical surgical excision of mass by transoral approach. Postoperative bleeding imposed angiography with right internal maxillary artery embolization. Histopathological evaluation showed the diagnosis of lymphangioma. After three years, the patient is without recurrence.

Advanced Atherosclerosis with Leriche Syndrome, in a Patient with Carney Complex.

Carney complex (CNC) is a rare autosomal dominant syndrome. Spotty skin pigmentation is the major clinical manifestation of CNC, followed by cardiac myxomas, benign tumors that usually present with features from the classical triad of obstructive cardiac, embolic and non-specific constitutional symptoms (NCS). NCS are caused by the overproduction of interleukin-6 (IL-6), a pro-inflammatory cytokine which mediates the induction of intercellular adhesion molecule 1 (ICAM-1) and promotes endothelial dysfunction and atherosclerosis. Thus, myxomas may be directly linked to an increased risk of atherosclerotic events. We report here a case of a 74-year-old woman with left atrial myxoma, skin pigmentary abnormalities, thyroid disorder and extensive atherosclerosis, with non-embolic occlusion of infrarenal abdominal aorta.

Transient Global Amnesia After Cerebral Angiography With Iomeprol: A Case Report.

Transient global amnesia is now considered a very rare complication of cerebral angiography. Various etiological mechanisms have been suggested to account for this complication, but no consensus has been reached yet. This case report documents one of the few reported cases of cerebral angiography-related transient global amnesia associated with magnetic resonance imaging (MRI) evidence of unilateral hippocampal ischemia, most probably as a consequence of a transient reduction in regional hippocampal blood flow. However, the possibility of a direct neurotoxic effect of the nonionic contrast media Iomeprol on the Cornu ammonis - field 1 neurons cannot be firmly ruled out.We describe the case of a 54-year-old woman admitted to our department for left upper limb weakness with acute onset 8 days before. The brain computed tomography (CT) scan performed at admission revealed subacute ischemic lesions in the right watershed superficial territories and a right thalamic lacunar infarct. Diagnostic digital subtraction cerebral angiography was performed 4 days after admission with the nonionic contrast media Iomeprol. A few minutes after completion of the procedure, the patient developed symptoms suggestive for transient global amnesia. The brain MRI performed 22 hours after the onset of symptoms demonstrated increased signal within the lateral part of the right hippocampus on the diffusion-weighted imaging (DWI) sequences, associated with a corresponding reduction in the apparent diffusion coefficient (ADC) and increased signal on the fluid-attenuated inversion recovery (FLAIR) sequences, consistent with acute hippocampal ischemia and several T2/FLAIR hyperintensities in the right watershed superficial territories and in the right thalamus, corresponding to the lesions already identified on the CT scan performed at admission. A follow-up MRI, performed 2 months later, demonstrated the disappearance of the increased signal within the right hippocampus on the DWI, T2/FLAIR, and ADC sequences.The precise mechanism of transient global amnesia related to cerebral angiography is still unclear, and further studies aimed to determine the definite pathophysiology of this syndrome and consequently to establish specific preventive measures are needed. Although the condition itself is considered to be self-limited, the long-term prognosis and the risk of recurrence in the cases where subsequent angiographic procedures are performed are not established yet.
