Anatomical Success

Aim: To assess reliability indices of Air Bubble Test (ABT) for anatomical and functional success in external Dacryocystorhinostomy (DCR). Methods: Prospective case series of nasolacrimal duct obstruction underwent DCR. Functional success defined as Munk score 0 & 1 & anatomical success as free irrigation at followup.ABT performed by putting antibiotic drops into eye& asking patient to exhale while keeping nose & mouth closed. Formation of bubbles at punctum considered as positive test. Specificity, sensitivity, positive & negative predictive values calculated. Results: There were 103 DCR in 97 patients(23 male,74 female)with mean age 45.56 yr. Anatomical and functional success was 99.02% & 98.05%, respectively.ABT showed sensitivity 96.07%, specificity 100% for anatomical success after DCR. Sensitivity and specificity were 97.02% & 100% for functional success. Conclusion: As non-invasive procedure ABT is a good tool to assess success of DCR, though lacrimal syringing remains the gold standard. Keywords: Anatomical, Dacryocystorhinostomy & Air Bubble Test.

Venous Access Devices

Persistent withdrawal occlusion is a specific catheter malfunction characterized by inability to withdraw blood through the device while infusion is maintained. The main causes are fibroblastic sleeve and tip malposition (associated or not to venous thrombosis around the tip). All current guidelines recommend infusing vesicant/antiblastic drugs through a central venous port only after assessment of blood return. In PWO, blood return is impossible. We have recently started to assess the intravascular position of the tip and the delivery of the infusion in the proximity of the cavo-atrial junction utilizing transthoracic/subxiphoid ultrasound with the ‘bubble test’. We found that this is an easy, real-time, accurate and safe method for verifying the possibility of using a port for chemotherapy even in the absence of blood return, as it occurs with persistent withdrawal occlusion.

Abstract Background Micro-bubble test by using transcranial color flow imaging (TCCFI) is important as a screening evaluation for diagnosis of paradoxical cerebral embolism which requires the proof of right to left shunt at atrial septum. In addition, high risk features of patent foramen ovale (PFO) that may allow thrombus to easily pass through the PFO itself were previously reported. However, little is known about the association between the degrees on micro-bubble test by TCCFI and the features of high risk PFO. Purpose Our aim is to clarify the relationship between the degree of micro-bubble test in TCCFI and the morphology of PFO from transesophageal echocardiography (TEE). Methods Seventy-seven patients in whom cardiogenic embolism was strongly suspected by neurologists in Showa University from April to December in 2019 were retrospectively studied. 55 patients underwent both TCCFI and TEE with sufficient Valsalva stress. TCCFI grade of micro-bubble test was classified into 3 groups (A: none, B: small, and C: massive), in which signified “none” is no sign of micro-embolic signals (MES) within 30 seconds, “small” is 1 or more MES, and “massive” is so much MES look like a curtain (Figure). Evaluated high risk characteristics of PFO for cerebral embolism as previously reported were as follows; (1) tunnel height, (2) tunnel length, (3) total excursion distance into right and left atrium, (4) existence of Eustachian valve or Chiari network, (6) angle of PFO from inferior vena cava (7) large shunt (20 or more micro-bubbles). Results Of all TCCFI-positive patients (n=32; Group B=19, Group C=13) with cerebral embolism, PFOs were detected in 23 patients in TEE. Therefore, the sensitivity and specificity of TCCFI to PFO were 87% and 63% (AUC=0.75, p<0.001, respectively). Interestingly, all 13 patients (Group C) had manifest PFOs. Moreover, group C include 2 patients with platypnea orthodeoxia syndrome in which hypoxia in the sitting position becomes apparent. Among PFO-positive patients, tunnel height, length, total excursion distance into right and left atrium, and large shunt in TEE were significantly larger in Group C than Group B (p<0.05). Conclusions Micro-bubble test by using TCCFI may have screening advantages in predicting paradoxical cerebral embolism, high-risk morphology of PFO, and platypnea orthodeoxia syndrome.

In einer bevölkerungsbasierten Studie untersuchten Wissenschaftler aus Oxford den Zusammenhang zwischen offenem Foramen ovale (PFO) und kryptogenen Ereignissen. Sie überprüften, inwieweit die kontrastverstärkte transkranielle Doppler-Sonographie zum Nachweis eines wahrscheinlichen PFO bei älteren Patienten mit transitorischer ischämischer Attacke (TIA) oder nichtbehinderndem Schlaganfall geeignet ist.

Pulmonary arteriovenous malformation (PAVMs) in children are rare lesions characterized by abnormal low resistance vascular structures connecting a pulmonary artery to a pulmonary vein, resulting in an intrapulmonary right-to-left shunt. The insidious onset and variable signs and symptoms make diagnosis difficult, especially in children. PAVMs  can be single or multiple, congenital or acquired, and up to 47-80% of cases are associated with hereditary hemorrhagic telangiectasia (HHT).We present the  case of a 12-year-old female teenager referred to our center for epistaxis, headache, fatigue and weakness, with evidence of mild oxygen desaturation.  Bubble test showed a right-to-left shunt and pulmonary angio-CT confirmed the diagnosis. Percutaneous selective embolization was performed with full recovery of normal arterial oxygen saturation. When differentiating between mild oxygen desaturation and exercise intolerance in children and adolescents, physicians should be aware of the possibility of PAVMs as a cause.
