We performed a 2-stage procedure combining balloon pulmonary angioplasty and pulmonary endarterectomy for a high-risk chronic thromboembolic pulmonary hypertension patient with high pulmonary vascular resistance. First, balloon pulmonary angioplasty was performed for distal lesions to improve hemodynamics and decrease the surgical risk. Subsequently, pulmonary endarterectomy was performed for proximal lesions, and the hemodynamics and symptoms improved dramatically. Our strategy was therefore found to be useful for treating a high-risk chronic thromboembolic pulmonary hypertension patient.

Hybrid Retrograde Celiac Artery Stenting for Acute Mesenteric Ischemia after Gastric Surgery.
Celiac artery (CA) occlusions/stenosis is infrequently associated with liver ischemia due to its unique vascularization, where portal vein provides about 75% of liver's perfusion. Collateral flow from gastroduodenal artery also provides, in most cases, enough blood supply to prevent ischemic hepatitis. In cases where these collateral pathways are compromised, severe liver ischemia can occur. ⋯ Ischemic hepatitis is a rare but serious complication of CA/SMA occlusive disease. Its occurrence is at increased risk after surgeries, where collateral flow is compromised. The endovascular treatment is currently the preferred approach to treat visceral arteries occlusive disease; however, antegrade CA cannulation can be tricky, and in an open abdomen scenario, retrograde approach from the splenic artery can be an additional resource. This case demonstrates the flexibility of endovascular techniques and that they can provide useful solutions even during open surgery.
