Arterial Embolization and Methylene Blue Injection into the Aberrant Artery in Two Infants with Intralobar Sequestration.

Bronchopulmonary sequestration is a rare congenital lung dysplasia. An intralobar sequestration (ILS) is a nonfunctional mass within the lung parenchyma without bronchial communication and with aberrant systemic arterial blood supply. Surgical resection or close observation can be proposed in the management of asymptomatic and low-risk ILS, but there is a lack of consensus. Endovascular embolization before thoracoscopic resection of ILS has been described to limit perioperative bleeding. Another technique previously reported is the injection of methylene blue in the feeding artery to macroscopically mark the sequestration from the healthy lung. In that way, a nonanatomical resection can be performed instead of a lobectomy without the risk of leaving abnormal lung tissue in place. We describe the first two cases of these two techniques combined: a 3-year-old girl with an ILS in the right lower lobe with an artery originating from the abdominal aorta, and a 14-month-old girl with an ILS in the right lower lobe with an artery coming from the celiac trunk. The combination of embolization and injection of methylene blue in the aberrant artery leads to a clear macroscopic demarcation of the blue-colored ILS from the healthy lung parenchyma and allowed safe nonanatomical resection of the ILS without risk of bleeding or compromising normal lung tissue.

Superior vena cava syndrome without thrombosis revealing Behçet's disease: Two cases.

Superior vena cava (SVC) thrombosis is a rare but well-recognized manifestation of Behcet's disease, whereas SVC syndrome due to vasculopathy, without evidence of thrombosis, has only been described a single time in the literature. We report two cases of this exceptional association. The two patients presented with swelling of the face and oral aphtosis, the SVC stenosis was evidenced by angio-CT and classical cavography. In each case, a combination of anticoagulant and immunosuppressive (corticosteroids and azathioprine) treatments allowed a significant improvement of SVC diameter. In one of the patients, an angioplasty of SVC was also performed. We believe there is a continuum between non-obstructive and obstructive vasculopathy (thrombosis) of SVC. Inflammatory vascular injury secondary to vasculitis is considered to be the primary reason for thrombosis in Behcet's disease. Thickening of the venous wall observed in our patients probably reflects this inflammatory vascular injury. In conclusion, Behcet's disease should be considered in the differential diagnosis of SVC syndrome not related to thrombosis.

Case report: cerebral vein thrombosis after subarachnoid analgesia for labour.

PURPOSE: We report a case of sagittal sinus thrombosis occurring after spinal analgesia for labour to highlight the difficulty of such diagnosis in the presence of postpartum atypical headache following regional anesthesia/analgesia. CLINICAL FEATURES: A previously healthy 21-yr-old, primiparous, preeclamptic parturient was admitted to the hospital at 37 weeks gestation for uterine contractions. Before pregnancy she was taking no medication other than oral contraceptives and was a non-smoker. Spinal analgesia was established on the first attempt at 8 cm of cervical dilation, in the setting of rapid progression of labour. Following an uneventful delivery, on the third day postpartum, the patient experienced gradual onset of an atypical headache with unclear postural character, followed by focal neurological signs five days later. Emergency neuroimaging revealed direct evidence of thrombosis in the posterior sagittal venous sinus. Anticoagulation was initiated with iv heparin (500 UI x kg(-1) x day(-1)). The patient's headache decreased progressively and full motor recovery was noted by day 14 postpartum. After 24 days, the patient was discharged without any neurological disability. Common inherited thrombophilic dispositions were absent, with the exception of a decrease in protein S level. CONCLUSION: Central venous thrombosis, while rare, is a recognized cause of puerperium stroke. The present case highlights the importance of considering the diagnosis in the presence of postpartum atypical headache following spinal anesthesia/analgesia. Early intervention with systemic heparinization is critical when the diagnosis is confirmed.

Percutaneous treatment of iatrogenic iliocaval fistula related to endograft placement for abdominal aortic aneurysm.

The authors report a case of iatrogenic dissection occurring during endovascular treatment of an abdominal aortic aneurysm. The dissection was related to catheterization maneuvers that led to the development of a symptomatic arteriovenous fistula, which was successfully closed by coil embolization.
