A delayed secondary open conversion (SOC) after endovascular aneurysm repair may be necessary due to a failing graft. Many surgical techniques can be performed, and one such approach is partial explantation of the graft with resuturing of a new graft to the retained components of the endograft. No guidelines exist ...

During parental development, the umbilical cord is physiologically and genetically part of the fetus and, in humans, normally contains a pair of arteries and a vein. The umbilical vein (UV) supplies the fetus with oxygenated, nutrient-rich blood from the placenta. In contrast, the fetal heart pumps deoxygenated, nutrient-depleted blood through ...

Despite advances in neonatal care, diaphragmatic hernia still inflicts significant morbidity and mortality on affected neonates. Abnormal embryologic events disrupt the formation of the diaphragm allowing the abdominal viscera to occupy the intrathoracic space. This interrupts normal pulmonary development with resulting pulmonary hypoplasia and pulmonary hypertension in neonatal survivors. This ...

A brachiocephalic arteriovenous fistula was complicated by a central venous stenosis, which could not be relieved. A cephalojugular bypass was performed using an interpositoned graft, which later developed tight stenoses at both ends of the graft. This was successfully treated with endovascular intervention, extending the longevity of the vascular access.

Mitral valve operations are increasingly performed through minimally invasive approaches such as the right anterior minithoracotomy. To facilitate exposure with this technique, a diaphragmatic suture may be implemented. We describe a liver laceration caused by the diaphragmatic suture in minithoracotomy mitral repair and its successful nonoperative management with arterial embolization.

Stenosis is the most frequent vascular access complication and is responsible for access thrombosis and thus long-term patency limitation. Regular arteriovenous graft (AVG) examination by ultrasonography and preemptive balloon angioplasty prolong AVG cumulative patency according to some, but by far not all trials. This was why the routine use of ...

Endovascular approach is now the first option for the treatment of most intracranial aneurysms (IA). However, remaining limitations are the suboptimal stability of aneurysm occlusion and the treatment of complex IA. The use of conventional and flow diverter stents has partially addressed these limitations. Nevertheless, as intraluminal devices, stents require ...
