Provisional side-branch stenting is currently the most widely accepted percutaneous technique for the treatment of bifurcation lesions. However, abrupt closure of the side branch may occur after main vessel stent implantation. Resolving side-branch stenosis under these conditions may pose major technical difficulties. We describe a new technique to resolve uncrossable side-branch occlusion foll...

Epidermolysis bullosa is a genetically transmitted skin disorder that typically manifests with trauma-induced skin blistering, scarring and in some cases mucosal involvement. Esophageal webs, strictures or stenosis can be found in about a third of the patients with the recessive dystrophic type of this disease. We report a six-year-old girl with recessive dystrophic epidermolysis bullosa and pr...

Cryoablation of pulmonary veins (PV)s to treat paroxysmal atrial fibrillation (PAF) is well established, however there are limited choices in balloon sizes for cryoablation. Data have recently been collected on a new cryoballoon system with novel capability deliver cryoablation standard 28mm diameter or an expanded 31mm diameter, using the same catheter. Demonstrate clinical utility expandable ...

Congenital or nonatherosclerotic dolichoectasia is a rare condition; its etiology, natural history, and indications and technique of treatment are not yet clarified. During a workup for recent headaches and left-sided paresthesia in a 48 year-old female patient, brain MR imaging and cerebral angiography showed a large dolichoectasia of the P2 segment of the right posterior cerebral artery (PCA)...

To date, no ideal endovascular strategy has been established for traumatic arterial occlusion. Here, we report the outcomes of a combination of endovascular recanalization techniques applied in two patients with high risk of leg amputation. A 33-year-old man with popliteal artery occlusion due to blunt trauma was treated by balloon angioplasty with long inflation time and aspiration thrombectom...

We report a clinical course of a patient who developed severe ischemic liver injury and total occlusion of the celiac artery (CA). A 40-year-old man presented with abdominal pain. Computed tomography indicated total occlusion of the CA. Laboratory data demonstrated markedly elevated hepatic enzymes. An exploratory laparotomy was not necessitated due to absence of peritonism. The patient was suc...

Measurements of dynamic lung compliance (Cdyn) were made on 42 occasions in a group of 15 intubated very low birthweight infants with respiratory distress syndrome, using an oesophageal balloon and pneumotachograph system. Values of Cdyn were compared with those of total respiratory system compliance (Crs) using an occlusion technique. Ten very low birthweight infants with no respiratory diseas...

Endovascular coil embolization for ophthalmic artery (OphA) aneurysms has a risk of occlusion of the OphA, which can lead to loss of vision. The authors report a patient with unruptured OphA aneurysm which treated with endovascular coiling and were complicated by blindness due to OphA thromboembolic occlusion after the procedure. The OphA successfully recanalized using local intra-arterial fibr...

Planning therapy is difficult for giant intracranial aneurysms, especially those of the vertebral-basilar circulation, which account for 8% of all giant intracranial aneurysms [1]. Using therapeutic neuroangiographic techniques, it is now possible to evaluate clinical tolerance of the occlusion of the afferent vessel to the aneurysm and to determine whether such an occlusion would effectively e...

Patients, methods, and results Over two years 30 patients were referred to this unit for the management of variceal bleeding with a balloon in position. Technical factors that we considered important for controlling bleeding were for the gastric balloon to be positioned close to the gastro-oesophageal junction and for it to be adequately inflated (in excess of 100 ml). Factors that we believed ...
