[Treatment of Renal Artery Perforation with Covered Stent after Percutaneous Biopsy of Pancreatic Head].

History And Clinical Finding: In a 67-year-old female patient with upper abdominal pain, computed tomography showed a partly calcified swelling of the pancreatic head and wall thickening of the duodenum.

Examinations: Inpatient physical examination findings were normal. Laboratory showed increased pancreatic enzymes (amylase 210 U/l [Standard range: 28-100 U/l], lipase 2115 U/l [Standard range: 23-300 U/l]) and inflammation values (CRP 11.

Percutaneous retrograde revascularization of chronic occlusions of the superior mesenteric artery via collaterals of the celiac artery.

Purpose: To evaluate the technical success of percutaneous retrograde revascularization of the superior mesenteric artery (SMA) via the celiac artery (CA) in patients with chronic mesenteric ischemia (CMI).

Methods: We performed a retrospective review of three patients with chronic total occlusions (CTOs) of the origin of SMA which were recanalized retrograde via collaterals of the CA after frustrating attempt of antegrade revascularization from the abdominal aorta in our institute between May 2019 and June 2020.

Results: All technical procedures of retrograde revascularization of CTOs of SMA via collaterals of the CA were successful.

[Acute right-sided upper abdominal pain in a 46-year-old woman].

A 46-year-old woman presented with acute abdominal pain in the right upper quadrant. Esophagogastroduodenoscopy revealed a duodenal stenosis within the horizontal part of the duodenum. Based on the findings of abdominal computed tomography (CT), endosonography, Doppler duplex sonography and angiography, the diagnosis of an aneurysm of a branch of the inferior pancreaticoduodenal artery was established.

[Unusual postoperative fistula of the abdominal wall, caused by an ingested wooden spit perforating the intestine and lodging itself in the abdominal wall].

Abdominal fistula caused by an ingested wooden spit, which penetrated the intestinal wall and remained in the abdominal wall: a laparascopy was performed in a 41-year-old man suffering from acute appendicitis and an inflamed Meckel's diverticulum. After removal of the appendix and the diverticulum, a fistula developed in the excision channel of the left quadrant of the abdominal wall post-operatively. Despite repeated incision of the abscess in the course of 2 months, the fistula did not heal.
