The Edwards Acumen IQ system using peripheral arterial catheter-based waveforms to estimate cardiac output is not accurate as compared to thermodilution in dogs.

Objective: To assess the agreement between cardiac output (CO) estimated via evaluation of the arterial pressure waveform by a novel monitoring system (Edwards Acumen IQ sensor and HemoSphere Advanced Monitor Platform [HS-IQ]; Edwards LifeSciences) and measured by thermodilution (TD) in anesthetized, normovolemic, and hypovolemic dogs. To assess the agreement between the HS-IQ CO measurements in the radial artery and dorsal metatarsal artery.

Animals: 8 purpose-bred Beagles.

Premature death in dogs with nontraumatic hemoabdomen and splenectomy with benign histopathologic findings.

Objective: To determine whether premature death occurred among dogs with nonmalignant splenic histopathologic findings after splenectomy for nontraumatic hemoabdomen.

Animals: 197 dogs with nontraumatic hemoabdomen that underwent splenectomy and histopathologic evaluation between 2005 and 2018.

Procedures: Information was obtained from electronic medical records, dog owners, and referring veterinarians to determine patient characteristics, histopathologic findings, survival information, and cause of death.

Outcomes of cellophane banding or percutaneous transvenous coil embolization of canine intrahepatic portosystemic shunts.

Objective: To compare clinical outcomes of dogs with congenital intrahepatic portosystemic shunts (CIHPSS) treated with cellophane banding (CB) or percutaneous transvenous coil embolization (PTCE).

Study Design: Dual-institutional retrospective study.

Animals: Fifty-eight dogs with CIHPSS (2001-2016).

Video-assisted extirpation of cranial mediastinal masses in dogs: 18 cases (2009-2014).

OBJECTIVE To characterize clinical findings, surgical procedures, complications, and outcomes in dogs undergoing extirpation of masses from the cranial mediastinum via video-assisted thoracic surgery (VATS) and establish preliminary guidelines for case selection when considering VATS for thymectomy in dogs. DESIGN Retrospective case series. ANIMALS 18 client-owned dogs that underwent extirpation of a cranial mediastinal mass by means of VATS at 5 academic referral hospitals from 2009 through 2014.

Comparison of surgical variables and pain in cats undergoing ovariohysterectomy, laparoscopic-assisted ovariohysterectomy, and laparoscopic ovariectomy.

Laparoscopy is an established modality in veterinary medicine. To date, laparoscopy in feline surgery is rarely reported. The objectives of this study were to compare surgical time, complications, and postoperative pain in a group of cats undergoing laparoscopic ovariectomy (LOVE), laparoscopic-assisted ovariohysterectomy (LAOVH), and ovariohysterectomy via celiotomy (COVH).

Pericardioscopic imaging findings in cadaveric dogs: comparison of an apical pericardial window and sub-phrenic pericardectomy.

Objective: To compare the pericardioscopic cardiovascular anatomy visible between apical pericardial window (PW) and sub-phrenic pericardectomy (SPP).

Study Design: Experimental study.

Animals: Canine cadavers (n = 5).

Evaluation of serosal patch supplementation of surgical anastomoses in intestinal segments from canine cadavers.

Objective: To compare leakage and maximum intraluminal pressures of intestinal anastomoses with and without serosal patch supplementation in dogs.

Sample: Healthy small intestine segments from cadavers of 2 dogs euthanized for reasons unrelated to the study.

Procedures: 12 enterectomy constructs were created by anastomosis of intestinal segments with a standard simple continuous suture pattern.

Outcome evaluation of a thoracoscopic pericardial window procedure or subtotal pericardectomy via thoracotomy for the treatment of pericardial effusion in dogs.

Objective: To evaluate the disease-free interval (DFI) and median survival time (MST) in dogs with idiopathic and neoplastic pericardial effusion surgically treated by a thoracoscopic pericardial window procedure or subtotal pericardectomy via thoracotomy and to compare DFI and MST in dogs with and without a mass on preoperative echocardiography that underwent either surgical technique.

Design: Retrospective cohort study.

Animals: 58 dogs with pericardial effusion.

Evaluation of a novel suture material for closure of intestinal anastomoses in canine cadavers.

Objective: To compare leakage and maximum intraluminal pressures for a novel suture material with pressures for comparable suture material when used in closure of intestinal anastomoses in canine cadavers.

Sample: Healthy intestines from cadavers of dogs euthanized for reasons unrelated to the study.

Procedures: 18 anastomoses were performed on intestinal sections within 72 hours after dogs were euthanized and intestinal samples collected.

Surgical time and severity of postoperative pain in dogs undergoing laparoscopic ovariectomy with one, two, or three instrument cannulas.

Objective: To determine whether number of instrument cannulas is associated with surgical time or severity of postoperative pain in dogs undergoing laparoscopic ovariectomy.

Design: Randomized clinical trial.

Animals: 18 healthy dogs.
