Abstract. Background: Effectiveness of vascular closure devices during endovascular procedures requiring a direct puncture of a vascular prosthesis placed in the inguinal region is unknown. Patients and methods: The retrospective analysis included 134 patients with a history of polyethylene terephthalate (PETE) graft implantation in the inguinal region. In 20 (15 %) patients, haemostasis was achieved with manual compression, in 21 (16 %) with the StarClose™, and in 93 (69 %) with the AngioSeal™ device. Results: The incidence of vascular complications in the manual compression group was higher (at a threshold of statistical significance) than in the device closure group (45.0 vs. 24.5 %, p = 0.059). The difference was considered statistically significant when manual compression was compared with the AngioSeal™ closure group (45.0 vs. 13.9 %, p < 0.01). The vascular complication rate in the StarClose™ group was significantly higher than in the AngioSeal™ group (71.4 vs. 13.9 %, p < 0.000001). While haematomas were the only vascular complications observed after application of AngioSeal™, both haematomas and pseudoaneurysms were found in the StarClose™ group. Conclusions: The AngioSeal™ vascular closure device provides better local haemostasis than the StarClose™ device or manual compression during endovascular interventions requiring a direct puncture of PETE grafts

We have attempted to dehydrate the lung interstitium to determine the nature of forces holding water in that compartment. We administered furosemide with and without bovine albumin intravenously to rabbits (n = 21) 1813;24 h before they were anesthetized with pentobarbital sodium. Renal pedicels were ligated and 51Cr-labeled EDTA was injected to estimate lung interstitial water volume. After a period of equilibration the thorax was rapidly opened, and left atrial pressure was measured by direct puncture. 125I-labeled albumin was injected to label the lung vascular volume, and the rabbits were killed 3 min later. Lungs were removed and drained of blood, and extravascular water volume, interstitial volume, and dry weight were determined. Results from these rabbits were compared with a group of normal (n = 4) and overhydrated (n = 6) rabbits. We have found that lung interstitial water is removed in proportion to the change in intravascular forces. We estimate interstitial compliance to be 1.76% cmH2O-1. Our results are compatible with the hypothesis that removal of water is opposed by an increase in interstitial colloid osmotic pressure and not by a fall of hydrostatic pressure. This implies that in the normally hydrated state interstitial hydrostatic pressure is ambient.

Abstract Background The access site for endovascular therapy (EVT) is often limited because of multi-vascular diseases. Prior lower limb bypass can potentially limit the availability of common femoral artery access when EVT is required. Case summary An 88-year-old woman who presented with non-healing ulceration in the dorsalis pedis of the left foot despite treatment for several months was admitted to our hospital. She had undergone axillo-bilateral femoral bypass surgery for right critical limb ischaemia 3 years previously. Ultrasound and contrast computed tomography demonstrated bypass graft occlusion, left superficial femoral artery (SFA)-popliteal artery long chronic total occlusion from the origin with severe calcification and severe stenosis in the bilateral common femoral artery close to the anastomotic site. EVT for the left SFA occlusion was necessary to save the left foot, but access sites for EVT were limited. We decided to puncture an occluded axillo-femoral prosthetic bypass graft. It is difficult to cross the wire with only an antegrade approach. Therefore, it was necessary to use a bi-directional approach with dorsalis pedis artery puncture and the Rendez-vous technique. Finally, angiogram demonstrated improved blood flow to the wound site, and haemostasis at the puncture site could be achieved by manual compression. The ulceration healed within a month. Discussion Direct puncture of a prosthetic bypass graft and additional techniques resulted in complete revascularization. Thus, direct puncture of a bypass graft could be a useful EVT strategy for patients with complex and extremely long chronic total occlusion.

Abstract The autosomal recessive transmission of Glanzmann's thrombasthenia (GT) and Bernard-Soulier syndrome (BSS), together with requests of families who already had children with these diseases, prompted us to investigate the feasibility of their antenatal diagnosis. The preliminary step leading to the early detection of GT or BSS was to characterize, in the normal human fetus, the platelet antigens and glycoproteins (GPs) and to define their normal amounts on the membrane surface. Blood samples from 32 fetuses between 18 to 26 weeks of gestation were collected by direct puncture of the umbilical vein using an ultrasound-guided needle. Polyclonal antibodies from human origin directed against PLA1, Leka antigens, and the GPIIb IIIa complex (IgGL), or murine monoclonal antibodies specific for GPIb (AN51, 6D1), GPIIIa (AP-3), or GPIIb IIIa (AP-2) were studied using platelet suspension immunofluorescence tests. The binding of each antibody was quantified using a cytofluorograph (Ortho 50H). PLA1 and Leka antigens were expressed in normal amounts on fetal platelets as early as 16 weeks of intrauterine life. The GPIIb IIIa complex quantified by polyclonal or monoclonal antibodies was in the same range in fetuses (IgGL = 427 +/- 23 AUF, AP-2 = 459.5 +/- 8.5; AP-3 = 536 +/- 14) and in adults (IgGL = 420 +/- 30; AP-2 = 498 +/- 11; AP-3 = 515 +/- 13). The platelet binding of antibodies that recognized GPIb was higher in fetuses (AN51 = 491.5 +/- 14; 6D1 = 479 +/- 15) than in adults (AN51 = 426.5 +/- 9; 6D1 = 449 +/- 8.7). These results suggest that immunological techniques can be applied as early as 18 weeks of gestation for the antenatal diagnosis of GT and BSS.

Transvenous Approach

Carotid-ophthalmic fistula is a rare disease, which can be treated by transvenous endovascular embolization. Here, we report a unique case with draining vein thrombosed, making a transvenous approach impossible. An old but valuable technique, direct transcutaneous puncture of the superior ophthalmic vein, was used to save the patient's right eye. The old technique, direct puncture of the superior ophthalmic vein, retains its irreplaceable usefulness in this special situation. Thus, interventional neuroradiologists should equip themselves with this essential technique.
