Minimally invasive spine surgery (MISS), including percutaneous pedicle-screw fixation (PPSF), mini-open transforaminal lumbar interbody fusion (m-open TLIF), vertebroplasty, and stentoplasty, allows the preservation of neurological function and the restoration of spine stability, while reducing associated risks and complications. This study aimed to analyze the safety and efficacy of MISS in elderly patients suffering from degenerative or traumatic thoracolumbar diseases. Forty-five patients (28 females), with a mean age of 73 years (range 65-89), suffering from osteoporotic vertebral fractures (24), degenerative spondylolisthesis (15), and lumbar canal stenosis with instability and/or de novo scoliosis (6) were included...

Endovascular repair has evolved to become a viable mainstream treatment for aortic pathology in both acute and elective settings. As technology advanced, traditional anatomical barriers were progressively tackled using new devices and novel procedures, and there are now multiple options available to the vascular surgeon. In the abdominal aorta, advances in endovascular aneurysm repair have been in the treatment of hostile aortic necks using new sealing concepts and ancillary procedures, and in branch preservation using fenestrations and snorkels...

Unresectable liver metastases of colorectal cancer can be treated with systemic chemotherapy, aiming to limit the disease, extend survival or turn unresectable metastases into resectable ones. Some patients however, suffer from side effects or progression under systemic treatment. For patients with metastasized uveal melanoma there are no standard systemic therapy options. For patients without extrahepatic disease, isolated liver perfusion (IHP) may enable local disease control with limited systemic side effects...

To apply endovascular aortic repair for arch or thoracoabdominal pathology, it is essential to reconstruct the branches originating in the treatment area. In cases that a stentgraft has to reach ascending aorta we perform "in situ fenestration with squid capture technique".During the procedure cerebral circulation is maintained by percutaneous cardiopulmonary bypass. After deploying the stentgraft we stab it by a needle while squeezed by snare wire and stick a covered stentgraft eventually. Unlike chimney technique which also can be applied for zone 0 thoracic endovascular aortic therapy( TEVAR),this method has no risk of gutter leak...

Endovascular aneurysm repair (EVAR) has become the predominant method of treatment for abdominal aortic aneurysms (AAA). The use of conscious sedation with local anesthesia and percutaneous femoral access has further decreased the morbidity of the procedure. Current devices can more effectively manage increasingly "hostile" aneurysm necks, while chimney grafts or dedicated fenestrated stent-grafts can be used for juxta-renal disease with favorable results. However, endovascular repair does present a new set of challenges, and endoleaks remain an area of concern...

BACKGROUND: Percutaneous femoral vascular access is frequently used for aortic endovascular procedures, with a local access complication rate of 5% to 16%. Fenestrated endovascular aneurysm repair (FEVAR) has recently emerged as a new technique for the repair of short-neck and juxtarenal abdominal aortic aneurysms. The safety and effectiveness of percutaneous access for FEVAR has not been established to date. METHODS: Since United States Food and Drug Administration approval of the Zenith fenestrated aortic endograft (Cook Medical, Bloomington, Ind), 94 patients (60 Zenith fenestrated, 6 p-Branch, and 28 custom-made devices) have undergone FEVAR...

Non-traumatic acute thoracic aortic syndromes (AAS) describe a spectrum of life-threatening aortic pathologies with significant implications on diagnosis, therapy and management. There is a common pathway for the various manifestations of AAS that eventually leads to a breakdown of the aortic intima and media. Improvements in biology and health policy and diffusion of technology into the community resulted in an associated decrease in mortality and morbidity related to aortic therapeutic interventions. Hybrid procedures, branched and fenestrated endografts, and percutaneous aortic valves have emerged as potent and viable alternatives to traditional surgeries...
