  • Pre-emptive triple tributary Internal Iliac Vein ligation reduces catastrophic haemorrhage from sacrectomy during pelvic exenterative surgery
    Techniques in Coloproctology, 2017
    Co-Authors: D. J. Coker, K. K. S. Austin, A. A. Eyers, C. J. Young
    Abstract:

    Background The risk of significant haemorrhage in pelvic exenterative surgery requiring sacrectomy has been well described. Patients requiring a sacrectomy above S3 are placed in the prone position, posing an increased challenge to gaining control of haemorrhage when it occurs. We describe a technique of pre-emptive control of the Internal Iliac Vein and its three named tributaries to tame the pelvis prior to sacrectomy. Methods A retrospective, descriptive analysis was performed on a cohort of 25 consecutive patients operated on by one of the authors (AA E) between January 2005 and December 2010; all of whom underwent pre-emptive Internal Iliac Vein triple tributary venous ligation, either unilaterally or bilaterally prior to sacrectomy above the level of S3. Results The cohort of patients was a heterogenous group ranging in age from 20 to 80 (mean 46.2) years, with primary tumours in 19 (76%), and secondary tumours in 6 (24%). Median operating time was 8.5 h (range 2.32–19.67 h). Median blood loss was 5500 mL (range 1600–18000 mL), with associated median transfusion of packed red blood cells of 9 units (range 0–34 units). Average stay in the intensive care unit was 1 day (range 0–10 days), with a median length of hospital stay of 18 days (range 5–148 days). There was no intraoperative mortality, with one death at 30 days secondary to gram-negative septicaemia. Postoperative morbidity occurred in 17 (68%) patients. Conclusion Our results show that pre-emptive triple tributary Internal Iliac Vein ligation is feasible for taming the pelvis prior to sacrectomy in the prone position where control of significant haemorrhage can prove challenging. The technique has broader relevance for visceral resections in the pelvis involving the pelvic side walls.

  • the role of intraabdominal pressure in venous blood drainage from the prostate into the vertebral Vein system
    Japanese Journal of Physiology, 1993
    Co-Authors: Takanori Suzuki, Kohei Kurokawa, Hiroyuki Jimbo, Tetsuo Sekihara, Hirotomo Takahashi, Masamichi Hayashi, Nobuo Kato, Hidetoshi Yamanaka
    Abstract:

    : We investigated venous blood drainage from the prostate into the vertebral Vein system by cineangiography in five mongrel dogs and measured intraabdominal pressure and venous blood pressure in the dog or human to study the role of intraabdominal pressure in the drainage. The averages of intraabdominal pressure and caudal vena caval pressure in the dog were 32.2 +/- 3.0 and 12.8 +/- 1.3 mmHg, respectively, in the supine position, and 39.2 +/- 3.0 and 23.8 +/- 4.0 mmHg, respectively, in the head-up tilt position, when the radiopaque medium injected into the dorsal penile Vein appeared in the vertebral Vein system. Intraabdominal pressure in the head-up tilt position was significantly higher than that in the supine position when the venous drainage into the vertebral Veins happened. In eight continuous ambulatory peritoneal dialysis patients, intraabdominal pressure showed 8.1 +/- 2.4 mmHg in the supine position, 24.6 +/- 4.3 mmHg in the sitting position, and 30.4 +/- 4.9 mmHg in the standing position at rest. During voluntary contraction of the abdominal muscles, the pressure was increased up to 50.6 +/- 21.6 mmHg in the supine position, 69.3 +/- 19.8 mmHg in the sitting position, and 73.8 +/- 19.8 mmHg in the standing position. These pressure values in the human were significantly higher than those observed at the time when the radiopaque medium appeared in the vertebral Veins in both supine and head-up tilt positions in the canine. These results suggest that the increase of intraabdominal pressure causes inflow of prostatic venous blood into the vertebral Veins via the inferior vena cava, common Iliac Vein, or Internal Iliac Vein.

  • correlation between the prostatic Vein and vertebral venous system under various conditions
    The Prostate, 1992
    Co-Authors: Takanori Suzuki, Kohei Kurokawa, Kazuhiko Okabe, Hidetoshi Yamanaka
    Abstract:

    : In dogs, the venous blood from the prostate gland was observed under X-ray fluoroscopy to drain into the vertebral venous system under conditions of abdominal compression, the addition of various intraabdominal pressures, and occlusion of the inferior vena cava by a balloon catheter. Pressure in the inferior vena cava and abdominal cavity were measured simultaneously. The venous blood draining from the prostate gland started to flow from the inferior vena cava into the vertebral Veins at more than 25 mmHg of intraabdominal pressure with the animal in the supine position. The average pressure of the inferior vena cava draining into the vertebral Veins was 12.8 +/- 1.3 mmHg in the supine position and 21.1 +/- 2.7 mmHg in the standing position. The average intraabdominal pressures were 35.5 +/- 3.9 mmHg and 30.1 +/- 2.8 mmHg, respectively. Under conditions of abdominal compression and balloon occlusion of the inferior vena cava, the materials flowed into the vertebral venous system from various routes, such as the Internal Iliac Vein, common Iliac Vein, and inferior vena cava. It was suggested that the inferior vena caval blood easily enters the vertebral venous system in the standing position by adding high intraabdominal pressure, and that the vertebral venous system may be useful for experimental study of drug administration in bone metastasis of prostate cancer.

  • Correlation between the prostatic vessels and vertebral venous system of the dog
    The Japanese Journal of Urology, 1991
    Co-Authors: Takanori Suzuki, Kohei Kurokawa, Kazuhiko Okabe, Tomoaki Hatori, Kyoichi Imai, Hidetoshi Yamanaka
    Abstract:

    : We examined the correlation between the intrapelvic vessels, especially prostatic vessels, and the vertebral venous system in the male dog by radiography. Aorta abdominalis branches the right and left external Iliac arteries at the 6th lumbar vertebra, and is divided into the right and left Internal Iliac arteries and arteria sacralis mediana at the 7th lumbar vertebra. Arteria urogenitalis arises from the Internal Iliac artery at the middle of articulatio iliosacralis, and is divided into arteria vesicalis caudalis cranially and arteria prostatica caudally. Arteria prostatica is divided in the prostatic capsule and distributed to the prostatic parenchyma in which arteries form the network. Vena prostatica is distributed to the prostatic parenchyma, forming the network and entered vena urogenitalis after joining vena vesicalis caudalis. Vena urogenitalis joins the Internal Iliac Vein, and then the common Iliac Vein and vena cava posterior after joining the external Iliac Vein. The anastomosis between the intrapelvic Vein and the vertebral venous system is formed by the vena intervertebralis. The vertebral venous system is anastomosis with the vena cava posterior, the common Iliac Vein, the Internal Iliac Vein and vena pudenda interna.
