Comparative Study
Thoracoabdominal aneurysm repair: hybrid versus open repair.
Hybrid repair of thoracoabdominal aortic aneurysms (TAAA) may reduce morbidity and mortality in high-risk candidates for open repair. This study reviews the outcomes of hybrid TAAA repair for Crawford extent I-III TAAA in high-risk patients in comparison to patients who underwent concurrent open TAAA repair. ⋯ Hybrid TAAA repair in high-risk patients has significant morbidity and mortality suggesting a non-interventional approach may be appropriate in many such patients. The morbidity and mortality of the hybrid TAAA repair was substantial even in lower risk patients (SVS risk score

Open abdomen treatment (OAT) is considered a lifesaving procedure in patients with abdominal compartment syndrome (ACS) after endovascular or open intervention for ruptured abdominal aortic aneurysms (RAAA). Standardized treatment methods and algorithms for its use are still lacking. The high, published mortality rates may reflect difficulties in detecting and treating ACS, especially in patients treated by emergency endovascular aneurysm repair (eEVAR). Presented are standardized algorithms for OAT, including a new technique using the vacuum-assisted closure (VAC) system developed during 10 years of experience with eEVAR for RAAA. ⋯ The use of standardized novel techniques and a treatment protocol and algorithm for OAT after eEVAR for RAAA were feasible and safe. It decreased the workload of the medical and nursing staff, enhanced patient comfort because the need for dressing changes was minimized, and likely contributed to lower overall mortality in RAAA patients. Delayed direct fascial closure was possible in most patients.

To assess the association of perioperative cardiac dysfunction during elective vascular surgery with postoperative outcome. ⋯ The presence of perioperative diastolic dysfunction as assessed with Vp is an independent predictor of postoperative CHF and prolonged length of stay after major vascular surgery. Patient age, gender, type of surgery, and renal failure were also predictors of outcome. Perioperative systolic function was not a predictor of postoperative outcome in our patients.

Open vascular surgical procedures have decreased since the advent of endovascular repair. Advances in spinal fusion techniques and artificial disc replacement have led to an increase in the need for anterior retroperitoneal exposure of the lumbar spine (ARES). Vascular surgeons participate as "exposure surgeons" for these cases due to their unique skills in dealing with retroperitoneal structures. We report a single center experience with this procedure and focus on injury pattern and preservation of open surgical training. ⋯ Vascular expertise is important in anterior retroperitoneal lumbar spine exposure. Minor venous injuries frequently occur during exposure and instrumentation. Significant vascular injuries, while rare, occur during instrumentation, therefore the vascular surgeon should remain present throughout the entire procedure. The vascular manipulations required during exposure of the L4-5 disc offer an excellent opportunity for open vascular surgical experience. Vascular surgeon involvement in these cases allows for prompt repair of vascular injuries and provides opportunities for the vascular surgery resident to augment his/her open surgical training.

Celiac artery compression syndrome (CACS) is an unusual condition caused by abnormally low insertion of the median fibrous arcuate ligament and muscular diaphragmatic fiber resulting in luminal narrowing of the celiac trunk. Surgical treatment is the release of the extrinsic compression by division of the median arcuate ligament overlying the celiac axis and skeletonization of the aorta and celiac trunk. The laparoscopic approach has been recently reported for single cases. Percutaneous transluminal angioplasty (PTA) and stenting of the CA alone, before or after the surgical relief of external compression to the celiac axis, has also been used. We report our 7-year experience with the laparoscopic management of CACS caused by the median arcuate ligament. ⋯ The laparoscopic approach to CACS appears to be feasible, safe, and successful, if performed by experienced laparoscopic surgeons. PTA and stenting resulted in a valid complementary procedure only when performed after the release of the extrinsic compression on the CA. Additional patients with longer follow-up are needed.
