Arterial puncture closure using a collagen plug, II. (VasoSeal).

Various vascular closure devices have come into common usage by most angio/interventional radiologists and cardiologists over the past 6 or 7 years. This has occurred despite the "real angiographers hold their own punctures" mindset that many of us learned in training. In our practice, we tried a number of different devices, but began using VasoSeal as our primary closure method in mid-1998. Since then, we have performed approximately 2400 procedures in which the VasoSeal device was deployed. The purpose of this article is to review the technique of VaseSeal closure of percutaneous arteriotomy sites.

[The scope and value of translumbar puncture of the renal pelvis (author's transl)].

Percutaneous translumbar pyelography is indicated when excretory urography has failed to demonstrate the cause or site of obstructive uropathy and retrograde pyelography is impossible, undesirable or contraindicated. Under prophylactic treatment with antibiotics translumbar antegrade pyelography is safe, simple and accurate and in selected cases the only diagnostic method to establish exact diagnosis without which appropriate therapy cannot be planned. The method is described and the results of 30 percutaneous translumbar pyelographies obtained from 2680 renal angiographies and 230 punctures of space-occupying lesions over 13 years are reported.

Lumbar puncture.

Lumbar puncture is the original neurological procedure. The technique is learned by the student first through observation then performance under supervision by a physician who has mastered the technique. It is one of the more difficult procedures in medicine because success is not only dependent on the skill of the physician but also the size, anatomy, and comfort of the patient. The technique, complications, contraindications, and treatment of the complications are reviewed. A discussion of the composition of normal cerebrospinal fluid (CSF) is included, as well as tables for diagnostic CSF studies for infectious, inflammatory, and neoplastic central nervous system disorders.

Pneumatosis cystoides intestinalis: confirmation of diagnosis by endoscopic puncture a review of pathogenesis, associated disease and therapy and a new theory of cyst formation.

Pneumatosis cystoides intestinalis (PCI) is the term for the formation of intramural gas filled cysts of unclear pathogenesis in the wall of the gastrointestinal tract. We report two patients with PCI where the diagnosis was confirmed by endoscopic puncture of a lesion, resulting in a complete deflation of the cyst, and two patients who underwent surgery. Endoscopy offers a safe and quick way to confirm the diagnosis of PCI. The immunohistochemical study revealed histiocytic cells and foreign body giant cells in the cystic wall, corresponding to a secondary histiocytic organization of gas-filled pseudocysts rather than to the widespread theory of gas-filled lymph vessels.

[In vitro and in vivo images of puncture devices in real time ultrasound. 2. Plastic instruments].

The article reports on a systematic sonographic examination of plastic puncture instruments in a water-bath and in an animal model. The plastic instruments used showed visualization of the lumen in a horizontal (longitudinal) cross-section. In an oblique longitudinal cross-section of an instrument filled homogeneously with water, only one echo generated at the tip of the instrument could be demonstrated. It was possible to achieve contrast enhancement of the plastic instrument by roughening its exterior or interior surfaces, by insufflation of air bubbles or by inhomogenization, using various plastic-cum-metal constructions. The effects produced in the water-bath were found to be similar to those observed in vivo.

[Cystic degeneration of the adventitia of the popliteal artery: ultrasound angiography-aided puncture].

A filiform stenosis of the popliteal artery was examined by sonography and the reason for the cystic lesion in the arterial wall was found to be an uncommon type of cystic degeneration of the adventitia. The narrow lumen could be demonstrated by sonography and the lesion was punctured under ultrasound control. A viscous secretion was removed and the patient's claudication was cured without recourse to surgery.

[Technique and tactics of biopsy including puncture].

The biopsy is the key for the exact diagnosis of bone and soft tissue sarcomas. However the biopsy implicates risks that eventually may significantly interfere with the prognosis. The steps of the biopsy can be differentiated in tactical and technical aspects. Tactical aspects include laboratory examinations (e.g. blood count, immunological, chemical tests) in order to establish the prebiopsy differential diagnosis, basic imaging procedures (bone scan, magnetic resonance imaging) and to discuss with the pathologist questions as which region of the tumor might be most informative, how should the material be preserved and whether a frozen section might be useful and allow for initiation of therapy as early as possible. Furthermore the site of the biopsy has to be carefully chosen, the compartments that need being passed through or opened up during biopsy must be considered. The technical aspects refer to the approach and tissue handling during the biopsy itself. Fine needle aspiration allows only for a cytologic, core biopsies for a histologic examination (however only of a small sample), while the open biopsy provides more material for more analyses. Any biopsy (open biopsy as well as percutaneous puncture) contaminates the path with tumor cells and increases the risk of systemic seeding. In order to keep these risks as small as possible the most careful technique and tissue handling is mandatory. The biopsy path has to be completely ('en bloc') resected later for local tumor control.

[Treatment of recurrent corneal erosion by puncture of Bowman's membrane].

16 patients (18 eyes) with a recurrent corneal erosion have been treated with anterior stromal punctures. The pain disappeared in 15 patients and remained unchanged for one patient. No recurrence was observed over a 18 months follow-up period (maximum 39 months) and no patient was complaining of glare. The technique is simple, effective, cheap and easily performed without special instrumentation.

[Embolization of a pseudoaneurysm of the hepatic artery with hemobilia by direct percutaneous puncture].

Haemobilia is a rare cause of gastrointestinal bleeding that carries a high mortality. It occurs as a complication of percutaneous trans-hepatic biliary drainage in up to 6% cases. The cause is usually a pseudo-aneurysm of the hepatic artery, which can be treated by trans-catheter embolisation. If this fails, direct puncture and embolisation of the aneurysm is a possible alternative to surgical ligation of the hepatic artery.

[Experience with sonographically controlled fine-needle punctures with permanent visual control (author's transl)].

With our new biopsy-device it is now possible to perform fine-needle punctures of lesions in the abdomen, thoracic cage, cervical region and extremities under continuous visual control. This intervention can easily be done with low risk for the patient and can be repeated whenever necessary. It has proven its advantages for amniocentesis as well, especially in cases with a low amount of amniotic fluid. Moreover, our new device allows the combination of sonographical and radiological interventions, for example of the kidneys.

[Retrograde catheterization of the ureter and pyelography using bladder puncture with a special trocar following Cohen's procedure for anti-reflux surgery].

The advancement technique according to Cohen has proved to be a simple and reliable antireflux procedure. Its major drawback is the impossibility of catheterization of the ureter following this operation because of the transverse position of the ureter. I propose a technique of retrograde catheterization of the ureter by bladder puncture with a special trocar in order to facilitate the insertion of the catheter and to avoid trauma of the ureteral mucosa.

Influence of anaesthetic agent on limb abnormalities observed following amniotic sac puncture.

In all of our previous studies into the effect of amniotic sac puncture (ASP) carried out on day 13 of pregnancy in mice, we have used intraperitoneal Avertin (tribromoethanol) as the general anaesthetic. In the present study, we used an inhalational anaesthetic (a mixture of halothane, oxygen and nitrous oxide in a ratio of 2:3:3). The principal difference between these two regimens is that even under optimal post-operative conditions when Avertin is used it can take between 45 and 90 min before complete recovery is achieved; when the inhalational anaesthetic is used, complete recovery is usually achieved within about 3-5 min. Because the experimental conditions were otherwise identical, this allowed the influence of the anaesthetic employed during ASP and the incidence of abnormalities induced on survival rate to day 19 of pregnancy to be studied. The survival rate was slightly higher when the inhalational anaesthetic was used, as was the incidence of limb abnormalities, although the overall incidence of gross abnormalities involving the palate, limbs and tail was not significantly different. The most marked difference, however, was in the incidence of syndactyly, which was significantly lower when the inhalational compared to the intraperitoneal anaesthetic was used: 26.6% v. 70.2% of the abnormal limbs analysed. A possible hypothesis is presented to explain this difference.

Ketamine anesthesia with or without diazepam premedication for bone marrow punctures in children with acute lymphoblastic leukemia.

Ketamine is a drug widely used for analgesia and sedation of children for diagnostic and therapeutic procedures. The authors investigated in a randomized controlled clinical trial if diazepam premedication would have a beneficial effect on side effects related to ketamine anesthesia for bone marrow punctures (BMPs) in children with acute lymphoblastic leukemia (ALL). Sixteen children 4 years or older at the time of BMP were eligible. The first 2 BMPs after complete remission was obtained were studied. BMPs were performed under ketamine anesthesia (1.0-1.5 mg/kg i.v.), as usual. Patients were randomized to receive 1 h before the first BMP blinded, either diazepam or placebo orally and before the second BMP the other way round. Blood pressure, heart rate, and oxygen saturation were monitored, and patients were observed for signs of anxiety, pain, and other side effects. The patients were interviewed after each BMP and asked for their preference 1 week after the second BMP. Ketamine anesthesia appeared as safe and effective after diazepam premedication as after placebo premedication. From the interviews and questionnaires, it was clear that half of the children preferred diazepam premedication because of less awful dreaming and more gradual falling asleep and waking up. Diazepam premedication may be useful for selected children with ALL receiving ketamine anesthesia for BMPs.
