“…In pigs, auricular and femoral SAP, MAP, and DAP measurements were very similar to each other across a wide measurement range (Bass et al. ). A previous study in three isoflurane anesthetized rabbits reported SAP on average 31 mmHg lower, MAP 9 mmHg lower and DAP 1 mmHg higher when compared to pressures measured in the carotid artery (Imai et al.…”

“…Indirect BP measurement has been widely applied to monitor BP in animals due to its convenience and non-invasiveness. However, in agreement of ACVIM guideline, validation of indirect BP measurement method is necessary to prevent misinterpretation of the anesthetized patient's condition [2,3]. Therefore, the present study focused on the validation of the agreement between direct and indirect BP measurements in the minipigs under different postures, in accordance with ACVIM guideline.…”

Blood pressure (BP) measurement plays a pivotal role in veterinary medicine for diagnosing cardiovascular disorders and monitoring anesthesia of animals. Although indirect BP measurement has been widely applied to monitor BP because of its convenience and non-invasiveness, it is still unclear whether indirect BP measurement is compatible with direct BP measurement in minipigs. In addition, the effect of animal posture during BP measurement is not well understood in minipigs despite its importance to cardiovascular performance. Therefore, both systolic and diastolic arterial BPs in minipigs were measured via femoral artery catheterization for direct BP measurement and using a compressive cuff as an indirect BP measurement under the dorsal or right lateral recumbent postures. Numerical values were processed by the Bland-Altman method to calculate the bias ± SD and the limits of agreement (LOA). In accordance with the American College of Veterinary Internal Medicine guidelines, the results between direct and indirect BP measurements were determined as apparent disagreements in both systolic and diastolic arterial BPs under all postures because of large bias ± SD and wide LOA. The results of the present will help prevent misinterpretation of the anesthetized patient's condition during monitoring of BP by indirect measurement.

“…Another less serious problem associated with transfemoral access is that repeat angiography is not straightforward due to anatomical disarrangement and surgical occlusion of the femoral artery resulting from the initial transfemoral approach. In comparative studies on auricular and femoral artery approaches to cardiovascular experimentation (3), pressure monitoring (10), and hepatic angiography (5), the transauricular arterial access has been reported to be as good as or better than the femoral approach in terms of reducing the time to complete the procedure. Carotid angiography of the right side with forceful injection of contrast media into the left auricular artery has been reported in multiple follow-up studies to be straightforward in a rabbit aneurysm model (2).…”

Cerebral angiography using transauricular access in a rabbit model: a new technique

Background Cerebral angiography in a rabbit model is widely used in the field of interventional radiology. Conventionally, the femoral artery is used for cerebral angiography in radiology departments. However, angiographic studies require surgical cutdown of the femoral artery, which is technically difficult. Purpose To evaluate a new cerebral angiography technique involving a transauricular approach in a rabbit model. Material and Methods In each of 10 rabbits, central auricular arteries were punctured in the right or left ear with a 20-gauge i.v. catheter. A microcatheter (2.0 F) with a 0.016-inch guide wire was introduced through the i.v. catheter and advanced to the aortic arch. The microcatheter and guide wire were advanced selectively into cerebral arteries and angiography was performed. Results Central auricular arteries were successfully punctured with 20-gauge i.v. catheters. After approaching the aortic arch, microcatheter tips and guide wires were advanced manually to cerebral arteries on both sides. Difficulties in selecting the carotid arteries were resolved by using a looping technique within the cardiac chamber. Microcatheter loops within the cardiac chamber disappeared or remained during artery superselection. Conclusion Transauricular cerebral angiography appears to be a feasible technique for brain or carotid intervention studies in rabbits. In addition, vertebral angiography using a transauricular approach is possible using the looping technique. Selection of carotid or vertebral arteries on each side was not difficult when the microcatheter and guide wire were looped within the cardiac chamber. The ear chosen for the initial puncture does not appear to be important.
