laparoscopic renal surgery after spontaneous Retroperitoneal Hemorrhage
The Journal of Urology, 2003Co-Authors: Fernando Hernandez, Peter A. Pinto, Louis R. KavoussiAbstract:ABSTRACTPurpose: We assessed the role of laparoscopic management in patients following spontaneous Retroperitoneal Hemorrhage from a renal tumor.Materials and Methods: A retrospective chart review revealed 4 patients with spontaneous Retroperitoneal Hemorrhage treated at our institution in the last 2 years. After conservative management elsewhere patients were referred for definitive therapy. Patient characteristics and tumor size were examined and correlated with ease of surgical dissection and surgical outcome. No patient had any history of trauma. Computerized tomography was used to identify the initial extent of Hemorrhage in all patients.Results: All patients underwent successful laparoscopic exploration without the need for open conversion. Three patients underwent radical nephrectomy and 1 underwent laparoscopic partial nephrectomy. Renal Hemorrhage extending outside of the renal capsule was associated with significantly more adhesions than renal Hemorrhage confined to the renal capsule. Mean patie...

Laparoscopic renal surgery after spontaneous Retroperitoneal Hemorrhage.

Three patients underwent radical nephrectomy and 1 underwent laparoscopic partial nephrectomy. Renal Hemorrhage extending outside of the renal capsule was associated with significantly more adhesions than renal Hemorrhage confined to the renal capsule. Mean patient age was 56 years (range 36 to 70). Mean Retroperitoneal tumor size was 5.3 cm (range 2.5 to 10). Three renal hematomas were extracapsular and 1 was subcapsular. Mean operative time was 182.3 minutes (range 59 to 235). Average estimated blood loss was 800 cc (range 150 to 2,100). Nontraumatic Retroperitoneal Hemorrhage of renal origin may be managed using traditional laparoscopic techniques with results similar to those achieved with open renal exploration. These cases may prove technically challenging due to fibrosis and associated tissue plane loss.

Delayed Retroperitoneal Hemorrhage during veno‐venous extracorporeal membrane oxygenation: a case report
Acute medicine and surgery, 2019Co-Authors: Gaku Sugiura, Ayumu Yamaoka, Hiroki Okuda, Hirotoshi Mizuno, Naofumi Bunya, Masato Saito, Hiroyuki Inoue, Eichi NarimatsuAbstract:Case There are several reports of Retroperitoneal Hemorrhage induced by percutaneous femoral cannulation for extracorporeal membrane oxygenation (ECMO). However, there are no reports of delayed Retroperitoneal Hemorrhage, which develops a few days after ECMO initiation and is unrelated to the ECMO cannulation. Herein, we report a rare case of delayed Retroperitoneal Hemorrhage during veno‐venous extracorporeal membrane oxygenation (VV‐ECMO).

Delayed Retroperitoneal Hemorrhage during veno-venous extracorporeal membrane oxygenation: a case report.
Acute medicine & surgery, 2019Co-Authors: Gaku Sugiura, Ayumu Yamaoka, Hiroki Okuda, Hirotoshi Mizuno, Naofumi Bunya, Masato Saito, Hiroyuki Inoue, Eichi NarimatsuAbstract:There are several reports of Retroperitoneal Hemorrhage induced by percutaneous femoral cannulation for extracorporeal membrane oxygenation (ECMO). However, there are no reports of delayed Retroperitoneal Hemorrhage, which develops a few days after ECMO initiation and is unrelated to the ECMO cannulation. Herein, we report a rare case of delayed Retroperitoneal Hemorrhage during veno-venous extracorporeal membrane oxygenation (VV-ECMO). A 54-year-old man was referred to our hospital because of severe acute respiratory distress syndrome. We initiated VV-ECMO. The patient had severe delirium and was confined to a long-term supine position to maintain circuit safety. On day 13, computed tomography unexpectedly revealed a large Retroperitoneal Hemorrhage spreading around the psoas muscle. Delayed Retroperitoneal Hemorrhage can develop during VV-ECMO management a few days after its initiation. Anticoagulant use and forceful muscular strain could be risk factors of delayed Retroperitoneal Hemorrhage.

massive Retroperitoneal Hemorrhage associated with femoral vein cannulation
Journal of Clinical Anesthesia, 1998Co-Authors: Takashi Akata, Tetsuzo Nakayama, Tadashi Kandabashi, Kenji Kodama, Shosuke TakahashiAbstract:Abstract The right external iliac artery was inadvertently punctured during attempted right femoral vein catheterization. Severe hypotension developed several minutes after the arterial puncture. Concurrently, a large right lower abdominal quadrant swelling (≈5 cm in diameter) became apparent. Laparoscopic observation of the Retroperitoneal region immediately revealed massive Retroperitoneal Hemorrhage. Abdominal computerized tomographic scan indicated development of a huge (≈10 cm in the maximum diameter) Retroperitoneal hematoma along the right psoas muscle from the level of the right external iliac vessels up to the level of the upper pole of the right kidney. Consideration of the anatomy of the "right" femoral and Retroperitoneal vessels ( ie , mediolateral relationship between the vein and artery) led us to conclude that the site for insertion of the needle was too proximal and the angle for advancement of the needle too low in our patient, allowing the needle to reach and injure the "incompressible" external iliac artery, thereby causing massive Retroperitoneal Hemorrhage. Although femoral vein catheterization has generally been considered a relatively safe method of intravenous access, a life-threatening serious complication can occur with the inappropriate technique used in our case.
