Intra-aortic balloon pump [IABP] was applied to 12 patients between July, 1987, and September, 1990. The 12 patients included 8 who were assisted with IABP intraoperatively; 4 patients used IABP postoperatively. 8 patients could not be withdrawn from cardiopulmonary bypass [CPB], but 6 of them [75%] were able to separate from CPB with IABP. They all were withdrawn from the balloon. Four [50%] of them are hospital survivors, and alive at the time of this report. 4 additional patients were assisted with IABP, postoperatively. 2 of them [50Yo] were withdrawn from the balloon but died. The overall survival and balloon weaning rates are 33.3% [4/12] % 66.7% [8/12], respectively. IABP was most effective when applied early to patients who had transient and reversible injury to the myocardium.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) has been accepted as an adjunct procedure for non-compressible torso hemorrhage in patients with hemorrhagic shock. With appropriate indications, REBOA should be performed for resuscitation regardless of the physician's specialty. Despite its effectiveness in traumatized patients with hemorrhagic shock, performing REBOA has been challenging due to physicians' lack of experience. Even though training in endovascular skills is mandatory, many physicians cannot undergo sufficient training because of the limited number of endovascular simulation programs. Herein, we share simulation video clips, including those of a vascular circuit model for simulation; sheath preparation; long guidewire and balloon catheter preparation; ultrasound-guided arterial access; sheath insertion or upsizing; and balloon positioning, inflation, and migration. The aim of this study was to provide educational video clips to improve physicians' endovascular skills for REBOA.

We have reported that oral administration of Saiko-Ka-Ryukotsu-Borei-To (SRB), a traditional Chinese formulation, inhibited the intimal thickening in carotid artery after balloon injury in cholesterol-fed rats. To elucidate its mechanism, the effects of SRB on migration and proliferation of vascular smooth muscle cell (VSMC) were examined in vivo and in vitro.

Budd-Chiari syndrome is an uncommon condition characterized by hepatic outflow obstruction. Direct suture of the injured Inferior vena cava in a patient with blunt hepatic trauma also may cause an equivalent condition. However, early diagnosis is possible with common symptoms and radiologic evaluation. Moreover, a transluminal approach with balloon angioplasty could prevent long-term complications of Budd-Chiari syndrome without repeated abdominal surgery.

Renal artery injury is a rare complication in blunt trauma, but can cause devascularization of the kidney, leading to renal failure. It requires early diagnosis and management. The treatment of renal artery injury still remains controversial, but recent studies have reported the successful treatment outcome with endovascular stent placement. Nevertheless, there is no standard treatment strategy in cases of pediatric patients. We report a case of a 16-year-old girl with right renal artery occlusion associated with a grade IV liver laceration. She was treated with only balloon angioplasty, and the kidney showed marked improvement of parenchymal perfusion with normalized renal function. Treatment with only balloon angioplasty can be a treatment option in pediatric patients with renal artery injury.

The pathobiologic process of arterial stenosis following balloon angioplasty continues to be an enigmatic problem in clinical settings. This study investigates the ability of demethoxycurcumin, a curcuminoid isolated from Radix Curcumae, to attenuate balloon injury-induced neointima(NI) formation in the rat carotid artery. It was found that demethoxycurcumin induced inducible heme oxygenase(HO-1) expression and inhibited dose-dependently cellular proliferation in rat vascular smooth muscle cells. Perivascular application of demethoxycurcumin immediately following injury significantly reduced NI area and NI thickness 2 weeks post-injury. Interestingly, treatment with tin-protoporphyrin IX, a HO inhibitor, reversed the effects of demethoxycurcumin on NI formation. These results implicate demethoxycurcumin as a potent new therapeutic agent that is capable of reducing post-angioplasty arterial stenosis through induction of the HO-1 expression.

Damage control surgery (DCS) is an abbreviated laparotomy procedure that focuses on controlling bleeding to limit the surgical insult. It has become the primary treatment modality for patients with exsanguinating truncal trauma. Herein, we present the case of a 47-year-old woman with liver, kidney, and superior mesenteric vein (SMV) injuries caused by a motor vehicle collision. The patient underwent DCS following resuscitative endovascular balloon occlusion of the aorta (REBOA). In this case report, we discuss the importance of priority setting in DCS for the treatment of multisystem damage of several abdominal organs, particularly when the patient has incurred a combination of major vascular injuries. We also discuss the implications of damage control of the SMV, perihepatic packing, and right-sided medial visceral rotation. Further understanding of DCS, along with REBOA as a novel resuscitation strategy, can facilitate the conversion of uniformly lethal abdominal injuries into rescuable injuries.

Purpose: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an emergency procedure and extremely time-dependent, and the proficiency of the physician is important. Due to a lack of REBOA education programs in Republic of Korea, few physicians have been trained in the procedure. In this study, we examined how REBOA education affects clinical outcomes in a single center. Methods: A retrospective study conducted from February 2017 to June 2020 at a regional trauma center. We collected data of patients who underwent REBOA and analyzed the factors that influenced the outcome. The patients were divided into the educated and non-educated groups (based on REBOA training received by their physicians), and the success and failure groups. Results: A total of 24 patients underwent REBOA during the study. There were eight patients in the success group and 16 patients in the failure group. There are no significant differences between the educated and non-educated groups in sex, age, ISS, shock, injury-to-REBOA time, injury mechanism, injury sites, arrest, access site, type of catheter, type of REBOA, target Zone, mortality, and the result of REBOA. The non-educated group had a higher risk for failure compared to the educated group in multivariate analysis (odds ratio [OR] 154.64, 95% confidence interval [CI] 1.11-22.60). Conclusions: Failure in REBOA is harmful to patients. The risk of failure is increased in the non-educated group. Physicians working in the trauma center or emergency department need to complete the REBOA education program.
